This patent application describes improvements to the design of semi-automatic pistols to enhance safety. Key features include making the pistol double action only, using roller bearings to support trigger and sear assemblies for a constant pressure trigger pull, blocking the firing pin from reaching the cartridge until the firearm is fully locked, and only allowing the sear to engage the firing pin when the trigger is pulled rearward. The design aims to eliminate accidental discharge from dropping or impact by requiring the trigger to be pulled for each shot.
This patent describes a firearm with a readily interchangeable bolt face. The bolt face is normally an integral part of the firearm's slide but restricts the firearm to a specific caliber. The invention removes the bolt face area from the slide and replaces it with separate bolt face inserts. This allows a single slide to be used with different caliber barrels by changing the bolt face insert. The insert has an external shape that fits into the slide and an internal shape designed for a specific caliber. Extractor grooves and ejector slots allow the insert to work with the firearm's extractor and ejector. This reduces inventory costs and allows a firearm to readily change calibers without replacing the entire slide.
The patent describes a cartridge ejector mechanism for firearms. It consists of an ejector slide mounted inside the barrel pivot block that is spring-loaded to move between a seated and eject position. The slide has a finger that engages the rim of the cartridge casing when seated. A sear engages a catch on the slide to hold it in the seated position against the force of the spring. Opening the breech causes a release to pivot the sear, allowing the slide to snap to the eject position and throw the casing out of the breech. This ejects the casing automatically instead of requiring manual removal.
This patent describes an extractor mechanism for a double barrel derringer firearm that can extract rimless cartridges. It includes a T-shaped extractor element supported in a T-shaped slot in the firearm barrel. The extractor engages extraction grooves in rimless cartridges in the cartridge chambers. A locking strap that pivots on the barrel locks it closed and can also partially extract both cartridges when opened. The extractor can then move laterally to release the partially extracted cartridges to be removed from the chambers.
The document describes a trigger mechanism for a firearm. The mechanism includes a hammer, sear, and disconnect rest. The sear translates along an axis between a rest position and break point, and then rotates around another axis from the break point to a disconnect position. As the sear moves from rest to break point, it rotates the hammer from a seated to a cocked position. Past the break point, the hammer spring forces the sear to disconnect, allowing the hammer to strike.
This document describes improvements to a single shot handgun. It details an improved locking mechanism for the receiver that securely locks it in the firing position. A longitudinal slot is cut into the receiver and a matching slot is cut into the frame. A lug inserted into the frame slot locks into the receiver slot, eliminating play. Finger tabs on the lug allow two-finger unlocking to pivot the receiver open for reloading. An improved hammer mounting and handle mounting incorporating a coil spring are also described.
The document describes a concealable firearm. The firearm is designed to be narrow in width for concealability, with the width not exceeding the minimum needed to safely contain the ammunition. The sides of the firearm are shaped to provide friction against the body to help maintain its position when concealed. A special trigger and hammer mechanism prevents accidental discharge if dropped or impacted.

The document describes a pistol with an improved firing bolt firing mechanism. Key points:
- The insert piece forms an open internal cavity containing guide surfaces for the firing bolt. This allows for a simpler design that is easier and cheaper to manufacture than prior concentric firing bolt/spring assemblies.
- The firing bolt has mating surfaces that rest on the guide surfaces, defining a free space for the firing spring between the bolt and barrel slide cover wall. This provides more space for a stronger spring.
- The firing spring is supported at its ends by the firing bolt and an opposing bearing surface in the insert piece. This eliminates the need for extra parts.
The new design results in a more reliable pistol that operates
This patent describes a firearm with a pivotally mounted barrel that can open to load cartridges. A hammer is cocked back manually and held in place by a latch connected to the trigger. Pulling the trigger releases the latch, allowing the spring-loaded hammer to fire the cartridge. Locking mechanisms prevent opening the barrel when cocked or cocking the hammer when the barrel is open, improving safety. The latch functions as both a sear to release the hammer and a hammer block except when the trigger is pulled, providing an optimal trigger pull for accuracy.
The document is a patent application for a less-lethal ballistic projectile launcher. It describes a lightweight, handheld launcher configured with two barrels in an over/under configuration that pivots between an open loading position and closed firing position. Each barrel has a metal sleeve insert and the device uses a traditional single-action firing mechanism to alternatively discharge rounds from each barrel to prevent simultaneous firing from both barrels.
The document describes a patent for a small, lightweight two-shot pistol. The pistol has two barrels arranged in an over/under configuration. It has a single double action trigger.

This patent document describes improvements to a gun design, including an improved barrel locking mechanism and a rebounding hammer mechanism. The barrel locking mechanism allows the barrel to be securely locked to the frame while accounting for manufacturing tolerances. The rebounding hammer mechanism uses a torsion spring to automatically return the hammer to a position where it is not in contact with the firing pins after firing, preventing accidental discharge when loading the gun. The document provides detailed drawings and descriptions of these mechanisms.
The document discusses a revolver with a separate firing control housing made of a lightweight non-metallic material such as polymer. This allows more of the component support structure to be made from a lighter material, reducing the overall weight of the revolver compared to all-metal designs. The polymer housing provides equal strength to aluminum but at half the weight. It also allows for an aesthetically interesting appearance compared to uniform metal frames.
This patent describes a barrel retaining device for an automatic pistol that allows for easy disassembly. The device has a single locking element that, when depressed, unlocks both the connection between the barrel and stock and the connection between the trigger arm and the firing pin driver. Depressing the locking element releases the trigger finger, allowing the trigger arm to move forward and cam downward to disengage from the firing pin driver. This single movement releases both the barrel and breech for removal from the stock.
The patent describes a firearm with a revolving barrel that unlocks from the bolt after firing. The barrel rotates slightly due to recoil, allowing an unlocking recess on the barrel to slide under locking protrusions on the bolt. This unlocks the barrel from the bolt. The firearm can be switched between single-shot and double-shot modes using a safety catch and separate draw bars connected to the trigger.
1) The document describes improvements in automatic rammer mechanisms for guns.
2) It aims to provide a fully automatic rammer that uses free-flight delivery of ammunition into the gun breech to minimize the time between rounds and protect the ramming mechanism from damage from premature breech closure.
3) Free-flight delivery also allows more accurate insertion of rounds into the breech under varying conditions like pitch and roll of the gun.
The patent describes a locking handle and pawl assembly that is mounted on a removable memory cartridge (RMC) to securely attach the RMC to a removable memory cartridge bay (RMC Bay). The assembly includes a handle base pinned to one or two locking pawls. Rotating the handle arm upward releases the pawls from catches on the RMC Bay, allowing the RMC to be removed from the bay with one hand while preventing displacement during shocks or vibrations.
The patent describes a steamer device comprising a body containing a steam generation unit. The device has first and second side panels attached to the body that provide wrapping locations for storage of a power cord and steam supply hose. The wrapping locations are formed between the body and side panels and allow the cord and hose to be neatly wrapped and stored when not in use.
This patent describes a mechanism for a semi-automatic pistol that blocks the firing pin except just before firing. It includes a rotatable firing pin blocking piece mounted in the frame. A trigger bar connected to the trigger engages the blocking piece just before firing to rotate it and unblock the firing pin. A sear associated with the blocking piece allows the mechanism to operate in single action, double action, and re-set modes. The blocking piece returns to the blocking position after firing to block the firing pin during other non-firing conditions.
The patent describes an apparatus and method for automatically retracting an awning. A sensor detects wind-induced acceleration of the awning and generates a signal corresponding to the acceleration. If the signal exceeds a sustained threshold for a set period of time or exceeds a peak threshold at any time, the awning is retracted. This protects the awning from damage during high winds.

[57] ABSTRACT
The safety of semi-automatic pistols and like ?rearms is
improved by making them double action only combined
with novel features that include use of roller bearings
for support of trigger and sear assemblies, structuring
them for constant pressure trigger pull, automatic
blocking the ?ring pin from reaching the cartridge until
the ?rearm is fully locked in the battery position and
structuring operation of the sear so it can engage the
firing pin only when the trigger pulls it rearward.

TRIGGER ASSEMBLY FOR A FIREARM
’ BACKGROUND OF THE INVENTION
1. Field of the Invention
This application relates to semi-automatic ?rearms
with improved safety features. More particularly it
concerns hand-held or shouldered semi-automatic guns
of the double action only type.
2. Description of Related Art
It is well known by police, military and other users of
semi-automatic handguns that their accidental dis
charge is a very serious problem. Accidental discharge,
often with fatal results, occurs by someone handling a
weapon which was “supposed” to be on safety or, alter
natively, which had its magazine removed and was
supposed to be empty. Accordingly, much attention has
been given, by designers, manufacturers and others
skilled in the art of manufacture and use of semi
automatic ?rearms, to their construction or adaptation
so as to avoid or mitigate the danger of accidental or
inadvertent ?ring.
The present invention further addresses this problem
and provides the art with unique improvements in ?re
arm construction that accomplishes this desired result.
The majority of semi-automatic pistols in use, includ
ing those used as side-arms by the armed forces of the
United States of America, are of the essentially single
action type in which a ?ring pin, typically impacted by
a hammer, is cocked into ?ring position by recoil of a
slide when the weapon is discharged by pull of the
trigger (see U.S. Pat. Nos. 984,519 and 4,754,689). Some
of these weapons may be double action on loading of
the ?rst round, but single action thereafter for all rounds
in the magazine, i.e., they are not double action only
weapons.
Such single action pistols are notorious for accidental
discharge and'various embodiments have been devised
to improve their safety. This has included modi?cation
of the sear mechanism to reduce potential for move
ment on dropping or other impact of the weapon (see
U.S. Pat. No. 4,646,619) and disablement of the trigger
upon removal of the magazine (see U.S. Pat. No.
4,420,899).
Double action type pistols are those in which the
?ring pin is not cooked by slide recoil, but wherein
trigger movement both cocks and releases the firing pin
for weapon discharge (see U.S. Pat. No. 3,857,325).
Since such pistols are not “armed” until trigger pull,
they have less potential for accidental discharge upon
being dropped or impacted. Still, accidental discharge is
possible in such ?rearms and embodiments of them have
been created to improve their safety, e.g., disablement
of the trigger upon removal of the magazine (see U.S.
Pat. No. 4,031,648). The present invention improves
upon the inherent safety features of double action type
?rearms by provision of improvements thereto that
virtually eliminate the possibility of their accidental
discharge by dropping or impact or because there was a
cartridge in the chamber of a gun from which the maga
zine had been removed.
One manner in which better safety in use and aiming
of pistols has been attained by this invention is to im
10
2
pin mechanisms. This appears to be a new innovation in
construction of pistols.
Another manner in which the invention improves
upon double action ?rearms is to interlock the slide and
barrel into a system that is not dependant on the frame
or frame side rails for proper alignment or function.
This has been done by utilizing rotary barrel and slide
interlock lugs (see U.S. Pat. Nos. 1,427,966 and
4,522,107) in a novel arrangement.
A further manner of the invention for improvement
of semi-automatic, double action pistols or other ?re
arms is through the use of an elongated, pivoted linkage
' unit between the trigger and the sear. Such linkages
25
35
40
45
55
prove tactile aspects of trigger operation so that the '
operator can have positive, constant “feel” control of
discharge. However, this is accomplished without sub
stantially increasing trigger pull effort by the use of
roller bearings in structuring of trigger, sear and ?ring
65
have been used in prior ?rearms (see U.S. Pat. Nos.
566,513; 1,395,455; 2,139,203; 4,301,609; 4,358,987 and
4,825,744), but the present invention provides novel
forms of such know type of ?rearm units to create the
new, improved semi-automatic, double action only
guns.
OBJECTS
A principal object of the invention is the provision of
new semi-automatic ?rearms with improved safety fea
tures.
Further objects include the provision of:
1. Improved hammerless pistols or other semi
automatic hand-guns wherein a ?ring pin is both cocked
and released for ?ring by a trigger mechanism in con
trast to the predominate type of semi-automatic guns in
which a ?ring pin or related hammer is cocked by the
recoil of the gun.
2. New semi-automatic hand-guns having triggers,
sears and ?ring pins that operate with relative low and
more constant friction as compared with prior known
hand-guns.
3. Such hand-guns that include a unique plunger as
sembly for positioning of the gun slide.
4. Such hand-guns that provide for a constant,
smooth trigger pull.
5. Such hand-guns in which‘the ?ring pin is positively
blocked and prevented from reaching the cartridge
until the barrel has been safely locked in battery posi
tion.
6. A hand-gun mechanism that insures the trigger has
moved into a full-forward position before the sear can
reengage the ?ring pin for subsequent discharge of the
weapon.
7. Semi-automatic hand-guns having a dual purpose
sear which functions to make the weapon drop safe.
8. Semi-automatic and-guns having an interrelated
slide, barrel and cam block independent of the gun
frame so that the frame is not subjected to any loads
induced on it by locking and unlocking of the slide and
barrel. _
Other objects and further scope of applicability of the
present invention will become apparent from the de
tailed descriptions given herein; it should be under
stood, however, that the detailed descriptions, while
indicating preferred embodiments of the invention, are
given by way of illustration only, since various changes
and modi?cations within the spirit and scope of the
invention will become apparent from such descriptions.
SUMMARY OF THE INVENTION
The objects are accomplished in accordance with the
invention by the provision of semi-automatic, double
action only pistols or like ?rearms that comprise (a) an
9. 5,050,480
3
elongated frame having a generally U-shaped, axial
cavity and an axial slideway de?ning an upwardly fac
ing longitudinal opening therein and (b) an elongated
slide mounted on the frame for movement along the
slideway between a slide battery position and a slide
recoil position.
There is (c) a drive spring assembly housed in the
cavity biasing the slide into the slide battery position,
(d) a barrel is rotatably and slidingly carried in the slide
and (e) cam means rotates the barrel between a barrel
battery position and a barrel recoil position.
The barrel can slide axially in the slide when in the
barrel recoil position and (f) integral lugs extend later
ally from the barrel to prevent its axial movement in the
slide when in the barrel battery position. A barrel bush
ing releasably ?tted to the muzzle of the pistol slideably
centers the barrel in the slide.
The pistol additionally has (g) a ?ring pin assembly
including a ?ring pin carried in the slide for axial move
ment between a retracted position and a ?ring position
through a safety position and (h) a ?ring pin safety
block assembly that positively prevents the ?ring pin
from reaching the ?ring position until the barrel has
fully rotated into the barrel battery position including a
stop lever pivoted on the slide.
In preferred embodiments, the pistol has (i) a trigger
assembly that includes a trigger that reciprocates axially
in the frame, a sear pivoted to the trigger for reciproca
tion therewith, and roller bearings supporting the trig
ger and sear in the frame for such reciprocation. Addi
tionally, the ?ring pin assembly includes a roller bearing
at least partially supporting the ?ring pin in the slide.
The trigger assembly also includes (j) means that
permits the sear to engage the ?ring pin when the sear
moves away from the ?ring pin ?ring position, but
prevents the sear from engaging the ?ring pin when the
sear moves toward the ?ring pin ?ring position. Such
means includes a plunger that holds the sear out of
contact with the ?ring pin when the sear moves toward
the ?ring pin ?ring position.
Preferably the sear comprises an elongated flat strip
member having a ?rst leg extending from its distal end
plus an upper second leg and lower third leg extending
from its proximal end, a ?ring pin engagement lug that
extends laterally from the second leg, and a cam surface
on the third leg. The frame carries a roller cam that
engages the cam surface to cause the sear to pivot
downward as the sear approaches the end of the move
ment of the sear away from the ?ring pin ?ring position
and the sear is pivoted to the trigger by the ?rst leg.
Advantageously, the frame includes a plunger that is
spring biased to move normally relative to the slide to
engage with an indentation in the slide to thereby aid in
the full closing of the slide into the slide battery posi
tion.

DESCRIPTION OF THE PREFERRED
EMBODIMENTS
With reference in detail to the drawings, the semi
automatic, double action only pistol 2 basically com
prises frame 4, slide 6, barrel 8, trigger assembly 10,
?ring pin assembly 12, sear 14, ejector 15, drive spring
assembly 16, magazine 18, magazine release unit 20,
barrel bushing 22, cam block 24 and slide stop unit 26.
The elongated frame 4 has a generally U-shaped,
axial cavity 28 along which the axial slideway 30 de?nes
an upwardly facing longitudinal opening 32. The slide
way 30 consists of right and left parallel channels 34
machined into the top sides 36 of the frame 4.
The frame 4 also comprises a trigger guard 38, right
and left grip portions 40, trigger slideway 42, saddle 44
for the cam block 24, magazine chamber 46, a cut-out
portion 48_to receive the stop unit 26, a bore 50‘to jour
nal the hub 52 of the stop unit 26 and pin bores 54 & 56.
The elongated slide 6 mounts on the frame 4 for
movement along the slideway 30 between a slide bat
tery position as shown in FIG. 5 and a slide recoil posi
10. 5,050,480
5
tion as shown in FIG. 10 by having its axial channel
portions 57 (see FIG. 12) engage the axial channels 34 of
the frame 4. The drive spring assembly 16 is housed in
the cavity 28 to bias the slide 6 into the slide battery
position.
The slide 6 additionally comprises a bore 58 and
channel 60 to receive the ?ring pin assembly 12, a rear
sight 62, a cartridge ejection opening 64, cartridge ejec
tor 66, semi-circular barrel lug locking channel 68, axial
barrel lug slide channels 70, retention pin bore 72, grip
serrations 74, complex axial channel 76 and a semi-cir
cular channel 78 to receive lugs 80 of the barrel bushing
22.
The barrel 8 is rotatably and slidingly carried in the
slide 6. It comprises ri?ing 82, lateral lugs 84, breech 86,
muzzle 88, bevel 90 and cam 92. In the barrel battery
position (see FIG. 9), the lugs 84 lock in the slide lock
ing channel 68, while in the barrel recoil position (see
FIG. 10), the lugs 84 slide in the slide channels 70.
Cam means 24 rotates the barrel 8 between barrel
battery position and a barrel recoil position. Thus, in the
assembled pistol 2, the barrel cam 92 rests in the cam
slot 94 and as the slide 6 begins to recoil interaction
between cam 92 and slot 94 causes the barrel 8 to rotate
clockwise (as viewed from the breech) about 10° so the
lugs 84 turn out of the channel 68 and into the channels
70. Conversely, as the slide 6 nears battery position,
movement of the cam 92 in slot 94 rotates the barrel 8
counter-clockwise so the lugs 84 turn into the channel
68 to prevent its axial movement in the slide when in the
barrel battery position.
As seen in FIGS. 15-20, the cam means 24 includes an
internal, longitudinal channel 96, external longitudinal
channels 98, bevel 100, lock bar 102, lock lever 104,
right shoulder 106 and left shoulder 108. In the assem
bled pistol 2, the shoulders 106 and 108 rest on the
saddle 44 of frame 4 and in this position, the channels 98
form a part of the slideway 30.
The bevel 100 serves as a guideway in loading a car
tridge from the magazine 18 into the breech 86.
_ FIGS. 16, 17 & 19 show the lock bar 102 and lever
104 in the slide lock position, while FIGS. 18 & 20 show
them in the slide unlock position which permits the slide
6 to move forward and out of the slideway 30 for disas
sembly of the pistol 2. Thus, as seen in FIG. 19, in the
lock position, the lock bar 102 closes the entrance into
the cam slot 94 to thereby prevent the barrel lug 92 for
moving out of the slot 94, but in the unlock position
(FIG. 18), the shape of the lock bar 102 is such that
entrance to the cam slot 94 is open and the lug 92 can
pass to permit the barrel 8 and slide 6 to move forward
on the slideway until they become free of the frame 4.
The trigger assembly 10 includes the trigger 110 that '
reciprocates axially in the frame 4 and the sear 14 piv
oted to the trigger 110 for reciprocation therewith.
Additionally, the assembly 10 comprises a longitudinal
portion 112, depending ?nger portion 114, plunger 116
and roller bearings 118. The portion 112 has an axial
bore 120 that slideably receives the plunger 116 and
contains a coil spring 122 to urge the plunger out of
portion 112. The frame 4 has a pair of axial grooves 124
juxtaposed to the trigger slideway along which the
roller bearing run when the trigger is pulled (see FIGS.
6-8).
The trigger assembly further has a second pair of
roller bearings 126 carried on the pin 128 ?xed in the
post 130 that extends up from the assembly portion 112.
The bearings 126 run in the cam means channel 96.

The sear 14 comprises an elongated ?at strip member
having a ?rst leg 132 extending to its distal end 134 plus
an upper second leg 136 and lower third leg 138 extend
ing to its proximal end. The sear is pivoted at its end 134
on the pin 128 ?xed to the trigger post 130.
A ?ring pin engagement lug 140 extends laterally
from the _second leg 136 and there is a cam surface 142
‘and a lateral lug on the third leg.
The frame 4 carries several items essential to the
proper operation of the sear 14, namely (1) a roller cam
146 that engages the cam surface 142 to cause the sear to
pivot downward as the sear approaches the end of its
movement away from the ?ring pin ?ring position (see
FIG. 4), (2) plunger 148 that reciprocates normal to the
plane of movement of the sear 14 and (3) plunger 150
with bias spring 152 that reciprocates in the plane of
movement of the sear 14. The interaction of these items
as explained later by reference to FIGS. 4-8 permits the
sear to engage the ?ring pin when the sear moves away
from the ?ring pin ?ring position, but prevents the sear
from engaging the ?ring pin when the sear moves
toward the ?ring pin ?ring position.
The roller 146 rotates on a pin carried in the frame
bore 56. The plunger reciprocates in the frame bore 54
which carries a bias spring (not shown) similar to spring
152.
The ?ring pin assembly 12 comprises a cylindrical
case 154, a bracket 156 that extends laterally from case
154 to hold a roller bearing 158, the ?ring pin 160 and a
spring unit 162.
The spring unit 162 has a coil spring 164 captured
between a front guide member 166, the tip of which
extends though a hole in the front of case 154, and a rear
guide member 168, the end of which carries a ledged
cap 170. The members 166 & 168 telescope together
when the spring 164 is ‘compressed by pull of the trigger
110.
When the pistol 2 is assembled, the case 154 of ?ring
pin assembly 12 ?ts into the slide bore 58 and the
bracket 156 and bearing 158 ?t into the slide channel 60.
An end plate 172 slips into grooves (not shown) in the
rear of the slide 6 and the end of cap 170 protrudes
though a hole in the plate 172 to lock these parts in
place. When so assembled in the pistol 2, the ?ring pin
assembly 12 is carried in the slide 6 for axial movement
between a retracted position (FIG. 4) and a ?ring posi- '~
tion (FIG. 5) through a safety position (FIG. 6).
Pistol 2 has a ?ring pin safety block assembly 174 that
positively prevents the ?ring pin 160 from reaching the
?ring position until the barrel 8 has fully rotated into the
barrel battery position. This assembly 174 includes a
stop lever 176 pivoted on the slide pin 72 and biased into
the ?ring pin blocking position (see FIG. 10) by a spring
178. The bevel 90 on barrel 8 allows lever 176 to pivot
into the blocking position when the barrel is rotated into
its recoil position, but when the barrel rotates into its
battery position the bevel 90 moves aside and the full
outside diameter of the barrel breech 86 pushes lever
176 up so the ?ring pin case 154 can clear it permitting
the ?ring pin 160 to engage and ?re a cartridge.
The drive spring assembly 16, which is housed in the
U-shaped, axial cavity 28 of the slide 6, serves to return
the slide to the battery position after recoil upon dis
charge of the pistol 2. This assembly 16 comprises a
longitudinal guide rod 180 surrounded by an inner drive
' spring 182 and an outer drive spring 184. The springs
are captured between a contoured cap 186 pinned to the
rear end of rod 180 and the washer 188 that is slideable
11. 5,050,480
7
on the rod 180, but prevented from sliding off rod 180
by the enlarged end 190.
The drive spring assembly 16 is captured in the cavity
28 by the barrel bushing 22 which comprises, in addi
tion to the lugs 80, the barrel chambering bore 192, the
drive spring chambering bore 194 with the hole 196 in
its forward end, the front sight 198, locking plunger 200
with land 204 and its bias spring 206 plus retainer pin
208.
When assembled in the pistol 2, the washer 188 of
assembly 16 abuts the front end of the bore 194 in bush
ing 22 and the end 190 of rod 180 protrudes through
hole 196. Thus, with the bushing 22 locked on the slide
6 by its lugs 80 plus plunger 200, the forward end of
barrel 8 is slideably carried in bore 192 and the forward
endof drive spring assembly is captured in the bore 194
(see FIG. 6). When the pistol 2 is discharged, the slide
6 recoils and moves back along the barrel 8 as its front
portion slides in bore 192 of bushing 22 (see FIG. 10).
At the same time, the springs 182 & 184 of assembly 16
are compressed until the slide 6 reaches the full recoil
position (not shown) whereupon the springs 182 & 184
return the slide to the battery position. This, in turn,
causes the barrel 8 to be moved into its battery position
by action of cam block 24 as previously described.
The recoil of the slide 6 as described discharges a
spent casing from the pistol 2 though the ejection open
ing 64 and loads a new cartridge (not shown) from the
magazine 18 into the barrel breech 86, but since the
pistol 2 is a double action only ?rearm, the recoil does
not cock the ?ring pin 160 which remains in its safety
position (see FIG. 9) throughout the entire recoil move
ment of the slide 6. This safety improvement in the new
semi-automatic pistol is attained by the unique features
and mode of operation of the trigger assembly 10 and
sear 14 which can be described with reference to FIGS.
4-8.
The safety position of the ?ring pin assembly 12 is
shown in FIG. 6 where the rear end of ?ring pin en
gagement lug 140 of sear 14 engages the front ledge 210
of ?ring pin assembly bracket 156. Also, roller cam 146
engages cam surface 142 of leg 138 while plunger 148 is
disengaged. Thus, as the trigger 110 begins to be pulled,
engagement of lug 140 with ledge 210 causes the ?ring
pin assembly 12 to be moved rearward (see FIG. 7)
while cam surface 142 continues to run along roller 146,
but plunger 148 is by-passed and begins to ride behind
leg 138 with the sear 14 biased upwardly by plunger
150. Further pull of trigger 110 eventually moves the
?ring pin assembly 12 to its rearmost position just be
fore the sear disengages (see FIG. 8). At this point, cam
roller 146 riding on the cam surface 142 forces the sear
14 downward overcoming the bias of plunger 150 and
two things immediately occur, namely, (l) the engage
ment lug 140 on sear 14 disengages from the ledge 210
of the ?ring pin assembly 12 and (2) the plunger 148
moves laterally across the top of sear leg 138(see FIG.
4). Immediately, the ?ring pin assembly ?ies toward the
?ring pin battery position (see FIG. 5). Also, as soon as
?nger pressure on the trigger 110 is released, the sear
moves forward, but plunger 148 continues to ride on the
top ofcam surface 142 of leg.138 thereby preventing the
sear 14 from moving upward until it reaches its full
forward position and clears the plunger 148 (see FIG.
6). This insures safety in the pistol 2 by requiring the
trigger 110 to move fully forward before the sear lug
140 can reengage the ledge 210 of the ?ring pin assem
bly 12 for subsequent shots of the pistol 2.

There are other features built into the ?ring pin as
sembly 12, trigger assembly 10 and sear 14 that combine
with the described novel sear action to provide the
improved safety to the new pistols of this invention.
Thus, the tactual characteristics of trigger action in the
new pistols serve to increase safety ofoperation. Firstly,
the use of roller bearings 118 & 126 for support of the
trigger and sear reduce friction and operate in a straight
motion not having to cam or lever any other trigger
part signi?cantly. This results in a substantially constant
tactual sensation to the pistol operator spread over a
recognizable period of time and eliminates accidental,
unintentional discharge of the weapon by a “nervous
?nger” gun user.
Secondly, the spring 164 in assembly 12 is a low-rate
type which combines with the roller bearings to pro
vide for the constant, smooth trigger pull that eliminates
unintentional discharge of the weapon via trigger pull
per se.
A third feature contributing to safety in the new
pistols of the invention is the inclusion in the frame 4 of
plunger 212 that is biased by spring 214 to move nor
mally relative to the slide 4 to engage with matching
detent 216 in the slide 4 to aid in the full closing of the
slide into its battery position insuring that the pistol 2 is
ready to ?re. The amount of pressure required to over
come the initial opening resistance of the slide 4 is con
trolled by regulation of the tension in spring 214. Incor
poration of plunger 212 in pistol 2 is a preferred option.
The magazine 18 is carried in the grip portion 40 of
the frame 4 and may be released from therefrom by
pressing on either the right or left side of the release
button 218 that extends laterally through the grip por
tion 40 and forms part of the release assembly 20 which
additionally comprises contoured plunger 220, maga
zine latch bar 222 and spring 224. Movement of button
218 in either direction froin its rest position depresses
plunger 220 causing latch bar 222 to move against the
bias of spring 224 out of the slot 226 in the magazine 18
freeing it for withdrawal from the grip portion 40 of
pistol 2. Other less complex arrangements may be used
for magazine release, e.q., a system (not shown) that
only releases from one side, but is changeable for right
or left handed users.
The slide stop unit 26 serves to lock the slide 4 in the
full recoil position when the magazine 18 is empty. This
is an added safety feature that warns a shooter that the
next pull of the trigger 110 will not result in ?ring of the
pistol. In addition to post 52, unit 26 includes lever 230,
cantilever wire spring 232, spring housing 234, hook
portion 236 and lug 238 that functions with ledge 240 on
the cartridge plunger 242 of magazine 18. The lug 238 is
sized so that it does not engage cartridges (not shown)
loaded in the magazine 18, but does engage the ledge
240 when plunger 242 is pushed to its top position by
spring 244. When this occurs, on the next recoil of slide
4, the hook portion 236 locks into the notch 246 in slide
4 and prevents the slide from returning to its battery
position. Removal of the empty magazine automatically
returns lever 230 to its lower position to unlock the slide
4 under the action of spring 232. The tension of spring
232 is less than the tension of magazine spring 244 per~
mitting the lever 230 to be raised against the downward
pressure of spring 232 when the magazine is emptied. '
The ejector 15 functions to eject spent cartridges
from the pistol 2 through the opening 64 following
discharge of the pistol and as the slide 6 recoils. It com
prises ?nger 248, body 250 and depending mount 252

containing hole 254. When assembled in the pistol 2, the
post 52 extends through the hole 254 to ?x ejector 15 in
the frame 4 to ride in the complex channel 76 in the slide
6 as the slide reciprocates.
The pistol 2 may be provided with a long barrel (not
shown) identical to barrel 8, but about 1 inch longer in
length to function with longer barrel bushings 22a and
/or 22b. Both longer bushings have a pair ofgas exhaust
slots 256 therein and are essentially the same except for
position of mount of the front sight 198 or 19817 and the
spacing of the exhaust slots 256.
A pistol 2 equipped with both short and long barrel
and regular and longer barrel bushings may be operated
in four different modes, namely (1) standard service
mode with short barrel 8 and regular bushing 22 as
shown in FIGS. 1 & 2, (2) compensated mode with
short barrel 8 and longer bushing 22a or 22b, (3) target
shooting mode with long barrel and longer bushing 220
or 22b and (4) silencer mode with regular bushing 22
and longer barrel having a silencer ?tted to the exposed
mussle of the longer barrel. In the compensated mode,
gas discharging through the slots 256 assists the shooter
to hold the gun muzzle down against the upward thrust
on recoil.
The pistol 2 is easy to maintain and service. Thus, it is
easily disassembled by swinging the lever 104 down as
seen in FIG. 3. The permits the barrel lug 92 to exit the
cam slot 94 and the slide to move forward and off the
slideway 30, provided the magazine 18 has been re
moved from the grip portion 40. With the slide re
moved, drive spring assembly 16 drops off the slide 6.
The barrel 8 is removed from slide 6 by rotation of
bushing 22 to unlock its lugs 80 from the slide groove
78.
Firing pin assembly 12 is removed from slide 6 by
pressing in cap 170 on assembly 12 and sliding the re
tainer 172 off the slide 6. Trigger assembly 10, sear 14
and cam block 24 are pulled off the saddle 44 as a unit
and when free of the frame 4, cam block 24 can be
separated from the trigger assembly 10 and sear 14.
Removal of slide 6 also permits stop unit 26 and ejector
15 to be pulled off the frame 4.
Servicing of several parts, e.g., items 146, 148 & 174
require the removal of retention small pins by use of
tools, but otherwise, the pistol may be assembled and
disassembled by hand without use of tools.
