Musical Gigarette Lighter.
1, Gui Do REUGE, a Swiss citizen, residing at No 21, sue des Rasses,
Ste-Croix, Canton de Vaud in the Confederation of Switzerland, do
hereby declare the invention, for which I pray that a patent may be
granted to me, and the method by which it is to be performed, to be
particularly described in and by the following statement:-
The present invention refers to a musical cigarette lighter.
According to the present invention there is provided a lighter
comprising a casing, a spring driven musical movement therein, cover
means for the wick of the lighter, the cover means being pivoted to
said casing, and means for winding the spring of the musical movement,
the winding means being arranged to be actuated by displacing said
cover means.
For a better understanding of the invention and to show how the same
may be carried into effect reference will now be made to the
accompanying drawings, in which each of Figs 1 to 4 is a cross-section
of a different embodiment of the musical Xighter.
The same numerals are employed for designating the same members in all
of the embodiments of Figs 1 to 4 The numeral 1 in Fig 1 designates
the outer casing of the lighter the interior of which contains the
musical movement 2, numeral 3 being the body of the lighter
incorporating the ignition device The arrangement comprises an

actuating lever 4 pivotably mounted at 5; one end of the lever 4 is
formed so as to cover the ignition wick when the lighter is not in use
(normal position).
The lighter also contains means for winding the spring of the musical
movement when the actuating lever 4 is pressed down to ignite the wick
These means comprise a push rod 7 passing through the interior of the
body 3 of the lighter, the lower end of rod 7 S connected to the
winding lever 785,954 No 23 '25,55.
8, rigidly fixed to the axle 9 on which the spring of the musical
movement 2 is mounted The upper end of the push rod 7 engages with the
actuating lever 4 The push rod 7 is connected with the lever 850
through a pin 9 ', which latter is slidable in a slot in the lever 8.
To actuate the lighter, the lever 4 is depressed, this pushes the rod
7 downwards the lever 8 is caused partially to rotate til 155 it is in
the position indicated by the dotted lines in Fig 1, in this position
the spring is fully wound On the lever 4 being released, the musical
movement is set in operation and the lever 8 returns to its 6 initial
position and at the same time the push-rod is moved upwards, the upper
end being in contact with the actuating lever 4.
In the embodiment of the invention represented in Fig 2, the lower end
of the 65 push-rod 7 is provided with a rack 10 engaging with a pinion
11 The pinion 11 is provided on the spindle or axle 9 on which the
spring of the musical movement is mounted The upper end of the
push-rod 70 7 is in contact with the lever 4, the operation being
similar to that described above, relating to Fig 1.
The lighter represented in Fig 3 comprises a cover 12, pivotally
attached to the 75 case 1 at 13, and normally held in position when
closed by means not shown in the drawing A push rod 7 ' passing
through the interior of the body 3 of the lighter is connected at its
upper end with the cover g 12 by means of a pin that can slide in a
slot 14 in the cover The lower end of the push rod is connected to a
lever 8 ' in a similar way as the lever 8 in Fig 1.
The spring of the musical movement is 85 wound up when closing the
cover 12 The push rod 7 ' is pushed downwards and actuates the lever 8
' till it reaches the position indicated by the dotted lines, the
spring is then fully wound up 90 (Price 3/6) 785,954 By releasing the
catch of the cover 12 the latter is opened by the action of the push
rod 7 ', which is pushed up by the lever 8 ' as the spring unwinds and
the musical movement plays Once the lid 12 is open, the wick 15 can be
ignited in the usual way from the serrated wheel 16.
In a further variation of the embodiment of the invention, the spring
of the musical movement can be mounted within the usual cylinder
provided with pins which co-operate with the vibrating blades of the
movement.

In the embodiment depicted in Fig 4, the winding lever is integral
with the barrel of the spring (not shown) which is rotatable instead
of being attached to the spindle of the spring In this case the
musical movement is set in motion when the actuating lever is operated
This embodiment comprises a push rod 7, one end of which engages with
the actuating lever 4 The other end co-operating with a winding lever
17, pivoted at 18 and under the action of a tension spring 19 The
lever 17 is pivotably attached to a crank lever 20 which in its turn
is connected with a lever 21 rotatably mounted on a stationary axle 22
This lever 21 is provided with a ratchet pawl 23.
The pawl 23 engages with a ratchet wheel 24 rigidly attached to the
barrel of the spring The wheel 24 engages with a retaining ratchet 25
When the lever 4 is depressed, the push rod moves downwards and the
ratchet 23 is moved in the counter clockwise direction, as seen in Fig
4, the wheel 24 is thus rotated through a preselected angle required
to wind up the spring When the actuating lever 4 returns to its
position indicated in the drawing, the spring 19 assures the return of
the winding lever 17 and its associated members into the position
shown in the drawing The ratchet wheel 24 is retained in its new
position by the ratchet pawl 25.
In the latter stage of the downward movement of the push rod 7, this
rod engages with a lever 26 which releases the musical movement Thus
by actuating the lever 4 the spring of the musical movement is wound,
and at the end of the path of travel of the lever, the musical
movement is set in motion by a mechanism, of which only the lever 26
is shown in the drawing.
SS In order to prevent overwinding the spring of the musical movement
when the lighter will not ignite, the spring in the barrel is mounted
with a friction device The spring may be rigidly fixed to a ring which
latter is in frictional contact with the wall of the barrel As long as
the tension of the spring is maintained within certain limits, the
ring is rotated when the barrel is rotated, thereby tensioning the
spring When the tension in the spring exceeds this predetermined
limti, the ring slips in the barrel.
In another varation of the invention in which the members for the
ignition of the wick can be actuated by means of a movable member of
the lighter, a push-button can 70 be mounted on the casing to start
the musical movement and at the same time means can be provided to
ignite the wick.
Each of the described embodiments can also be combined with a watch
movement 75 with a gearing means between the winding mechanism of the
watch movement and the actuating mechanism of the lighter The musical
movement can be provided separately or in combination with the watch
80 movement.

In order to spare the spring of the watch movement, the winding means
can be provided with an automatic winding mechanism like those which
are used in wrist watches, 83 i.e the spring of the wrist watch being
wound in consequence of any movement of the arm upon which the watch
is carried.

Improvements relating to Axial-flow Air Compressors.
We, GENERAL MOTORS CORPORATION, a Company incorporated under the laws
of the State of Delaware in the United States of America, of Grand
Boulevard in the City of Detroit, State of Michigan, in the United
States of America (Assignees of JOHN B. WHEATLEY), do hereby declare
the invention for which we pray that a patent may be granted to us and
the method by which it 1 ois to be performed, to be particularly
described in and by the following statement: -
This invention relates to axial flow air compressors such as those

suitable for aircraft gas turbine engines, and is more particularly
concerned with air bleed valve apparatus for such compressors.
The scope of the invention is defined by the appended claims; how the
invention may be carried out is particularly described below with
reference to tile accompanying drawings in which:
Fig 1 is a side elevation of an aircraft gas turbine engine
incorporating the invention; Fig 2 is an enlarged partial section
through an intermediate stage of the compressor portion of the engine
taken substantially on the plane indicated by the line 2-2 of Fig l;
and Fig 3 is a partial section taken substantially on the plane
indicated by the line 3-3 of Fig 2.
Referring now to the drawing and more particularly to Fig 1, the gas
turbine engine shown includes a multi-stage axial flow air compressor
10 that discharges through a diffuser 12 into combustion chambers 14
which are supplied with fuel by a fuel manifold 16 An axial flow
turbine 18 for drivX 4 ing the compressor 10 receives the products of
combustion from the combustion chambers 14 and discharges them to
atmosphere through an exhaust nozzle 20.
To vent compressed air from an intermediate stage to improve
compressor performance during starting and low speed operation, an air
bleed valve apparatus is provided Referring to the remaining figures,
the compressor 10 includes a cylindrical outer casing formed by four
arcuate (quad 50 rantal) sections 22 that are retained in assembled
relation by longitudinal rows of bolts 24 and nuts 26 A rotor 28 is
housed in the casing and carries axially-spaced annular rows of blades
30 Stator vane assem 55 blies are supported on the cylindrical inner
surface of the compressor outer casing in alternating relation with
the rows of rotor blades.
Each of the stator vane assemblies in 60 cludes four arcuate
(quadrantal) outer shroud strips 32 each carrying an arcuate row of
stator vanes 34 and an arcuate inner shroud strip 36 An assembled
stator vane assembly therefore comprises inner and 65 outer shroud
rings joined by an annular row of radial vanes An intermediate one of
the stator vane assemblies is provided with a circumferentially
extending annular row of radial air-bleed apertures 38 that extend 70
through each of the outer shroud strips 32 between the vanes 34 The
inner surface of the outer casing is recessed to receive the edges of
each of the intermediate shroud strips 32 through peripheral tongue
and 75 groove connections 40 and 42 and also to define, with the outer
surfaces of the intermediate shroud strips, a peripheral chamber 44
that communicates with the compressor interior through the shroud
strip apertures 80 38 A circumferentially extending row of radial
air-bleed apertures 46 extends through the arcuate outer casing
sections 22 to place the chamber 44 in communication with the exterior

of the casing 85 A small amount of radial clearance is provided in the
chamber 44 between the casing sections 22 and the intermediate shroud
strips 32 to support for circumferential sliding movement, four
arcuate slide go 1 Price $,) l#At No 33245/55.
v-alves 48, each made of thin flexible metal strip Each slide valve 48
has an arcuate row of radial valve Dorts 50 which are regisrable with
the apertures 46 to bleed off rressurized air from the intermediate
comnression stage of the compressor when required.
Each of the slide valves 48 is provided with an actuating means for
shifting it circumferentially in the casing to open and close the
valve passages 46 Each actuating means includes a rack 52 slidably
mounted an a housing 54 secured on the respective casing section 22
and a worm 56 rotatably mounted in the housing in engagement with the
rack Radial pin portions 58 project from the racks 52 and engage the
respective slide valves 48 to shift the same circumferentially on
rotation of the worms 56 Flexible drive cables 60 extend around the
compressor casing and interconnect the worms 56 for simultaneous
operation and any one of the flexible cables may be driven to
accomplish simultaneous actuation of the four valve members As shown
in the drawings.
the worms 56 are each rotatable about an axis approximately tangential
to the circumference of the outer casing 22.
The valving arrangement described above gives high quantity air
bleed-off when open due to the large number of valve ports, and
reduces air leakage when closed as the valve strips are then tightly
seated against the cylindrical internal surface of the compressor
casing by the air pressure within the compressor The slide valves, the
stator vane assemblies and the casing are parted radially into similar
arcuate sections to simplify their assembly with the compressor rotor.

COMPLETE SPECIFICAT 1 ON Improvements relating to Suitcases, Brief
Cases and other Hand Luggage.
1, ARTHUR BATES, Chevet House, Newnifilerdam, Wakefield, Yorkshire,
British, do hereby declare the invention, for which 1 pray that a
patent may be granted to me, and the method by which it is to be
performed, to be particularly described in and by the following
statement: -
This invention relates to suitcases, brief cases and other hand
luggage and provides a supporting strap of woven fibre or leather or
other durable and pliable material generally of a width of
approximately threequarters of an inch, but alternatively of such
other width as is convenient and appropriate to the weight to be
carried, which is disposed between two opposing sliding buckles,
provided with links or loops and attached to the hand luggage.
The strap is fitted in a manner described below so that the movement
of the buckles along the strap causes the effective length of strap to
be variable at will between maximum extension, when the strap can be
used to support the luggage from the shoulder, to maximum retraction,
when the strap lies taut along the upper surface of the luggage with
that portion of the strap between the sliding buckles lying in three
or more overlying and contiguous folds.
The ends of the strap are secured to links which are rivetted or
otherwise attached close to the outer angles of the upper surface of
the luggage and its length is so adjusted that -when the strap is
fully retracted the buckles are approximately half an inch from the
securing links.
The buckles are, generally, of a normal commercial type such as is
used for the se4 curing of the side adjustment straps of the
waistbands of trousers which are self-locking when tension is applied
to the strap, but are here used in opposing pairs and additional inner

links are fitted as necessary.
4, The sliding buckles shown are one type only of the many types in
commercial use which can be used in conjunction with this arrangement
of buckles and strap.
When it is necessary to use the strap for the purpose of supporting
luggage from the shoulder both of the sliding buckles are 50 moved
along the strap by hand towards the centre of the case This lessens
the length of strap contained in multiple layers between the two
sliding buckles and increases the length contained in a single layer
be-55 tween the securing end links of the strap and the two sliding
buckles, and the effective overall length of the strap is thereby
increased so that the strap may be slung over the shoulder and the
weight of the lug 60 gage supported thereon.
In Figs 1 and 2 on the accompanying drawings a typical arrangement is
shown in which only one inner link, at ' d ' on each of the sliding
buckles is employed and three 65 layers of strap connect the two
buckles Any convenient odd number of layers can however be used by
adding further inner links at ' d ' to each buckle.
In Fig 4 on the accompanying drawings a 70 sketch plan of the reverse
side of the buckles is shown with two inner links 'd' to each buckle
and five layers of strap between.
The strap is there shown diagrammatically by a narrow band in order to
indicate more clearly the arrangement of the strap and buckles.
In Fig 2 on the accompanying drawings the strap is threaded in the
following man 80 ner: If the left and right side sliding buckles are
lettered respectively 'X' and Y' then the strap is passed under the
bar a' of buckle 'X,' over the sliding grip b,' under the bar 'c,'
and, passing under 85 the link or link 'd,' passes along the ton
surface of the case and under and through the link 'd' of buckle 'Y'
and is then brought back along the top surface of the luggage and lies
along and over the first 90 layer to the buckle 'X' and passed under
(Price 316) 785,956 and through the link 'd,' and returned again to
the buckle 'Y' where it passes over the moveable link 'd,' under the
inner bar 'c,' over the moveable grip 'b' and under the outer bar 'a '
The two ends of the strap are then secured to the links attached near
the outer angles of the upper surface of the luggage with the sliding
buckles as near to these links as is possible and convenient.
Fig 3 on the accompanying drawings shows typical arrangements of the
strap fitted to a suitcase and to a brief case.

Improvements in or relating to Electric Circuit Interrupters.
Wve, W/ESTINGHOUSE ELECTRIC INTERNATIONAL COMPANY, of 40 Wall Street,
New York 5, State of New York, United States of America, a Corporation
organised and existing under the laws of the State of Delawvare in

said United States of America, do hereby declare the invention, for
which we pray that a patent may be granted to us, and the method by
which it is to be performed, to be particularly described in and by
the following statement:-
This invention relates generally to circuit interrupters and, more
particularly, to arcextinguishing structures therefor.
The chief object of the present invention is to provide an improved
circuit interrupter in which improved and more efiective
arcextinguishing action takes place.
With the above object in view, the invention consists primarily in an
electric circuit interrupter comprising means for establishing an arc,
a magnet structure including an elongated or oblongs shaped core and
pole plate portions for assisting in the extinction of the arc,
magnetic blowout coil means encircling the core to establish a
magnetic Held therein, a transfer arc horn spaced away from a long
side of the core, one terminal of said blowout coil means being
Unconnected to said transfer arc horn, and a relatively long transfer
arc-extinguishing structure disposed between said transfer arc horn
and a long side of the core to effect extinction of a portion of said
arc.
According to another aspect of the present invention there is provided
an electric circuit interrupter comprising means for establishing an
arc, a magnet structure including an elongated or oblong shaped core
and pole plate portions for assisting in the extinction of the arc, a
plurality of serially related magnetic blowout coils encircling the
core to establish a maanetic field therein, a pair of transfer arc
horns, one of said 4 transfer arc horns being spaced away from one of
the long sides of said core and con nected to one of said blowout
coils and the other of said transfer arc horns being space-; away from
the opposite long side of satc I core and connected to another of said
blow 50 out coils, and a relatively long transfer areextinguishing
structure disposed between a long side of the core and each transfer a
2.
horn to effect extinction of a portion of said arc 55 In order that
the invention may be more clearly understood and readily carried inlo
effect, reference will now be made to the accompanying drawings, in
which:
Fig 1 is a side elevational view, partially 6 C 7 in vertical section,
of a circuit interrupter embodying the principles of the present
irvention, the contact structure being shown in the closed-circuit
position.
Fig 2 is a plan sectional view of the cir 65 cuit interrupter of Fig
1, taken along the line II-II thereof; Fig 3 is a vertical sectional
view taken along the line III-III of Fig 1; Fig 4 is a side

elevational view of one 70 of the plates utilised in the
arc-extinguishing sections; Fig 5 is a side elevational view of or of
the transfer arc-extinguishing plates; Fig 6 is a sectional view taken
substan-7 r tially along the line VI-VI of Fig 7; and Fig 7 is an
enlarged fragmentary sectional view taken substantially along thse
line VII-VII of Fig 3.
Referring to the drawings, and more par 8 ticularly to Fig 1 thereof,
the reference numeral 1 generally designates a circuit irterrupter of
the air-break type.
Generally, the circuit interrupter 1 includes contact structure 2
operable to establish an 85 arc, which is moved upwardly into an
arcchute structure 3, including a pair of arcextinguishing sections 4
and 5 of substantially identical construction.
One terminal L 1 of the circuit interrupter 50 (Price 316) 785,957 is
connected to a stationary contact 6, and another terminal L 2 of the
interrupter is electrically connected to the movable contact 7 If
desired, suitable bridging and secondary contacts may be employed to
relieve the stationary and movable arcing contacts 6, 7 from carrying
the current in the fully closed circuit position shown in Fig 1.
During the opening operation, the moving loarcing contact 7 moves away
from the stationary arcing contact 6 to establish an arc 8, as shown
by the dash line of Fig 1 This arc may be considered as being composed
of three sections 8 a, 8 b and 8 c The arc 8, Of course, bows upwardly
because of the natural convection current of air, which is heated by
the arc, and also because of the magnetic forces set up by the arc
which act to expand the loop of the arc, as well understood by those
skilled in the art.
Adjacent the top and central position of the arc 8 is a pair of
transfer are horns 10.
11, between which is disposed a transfer arc-extinguishing means,
generally designated by the reference numeral 13 The arc portion 8 a
extends between the movable arcin contact 7 and the transfer arc horn
The arc portion Sb extends within the transfer arc-extinguishing means
13 between the transfer arc horns 10, 11 The arc portion 8 c extends
between the stationary arcng contact 6 and the transfer arc horn 1.
The function of the transfer arc-extinguishing means 13 is to
interrupt the arc portion 8 b and so bring into series circuit the
pair of serially related, centrally disposed blowout coils 15, 16, the
locations of which are more clearly shown in Fig 2 of the drawings
Such coils, of course, have insulated windings As mentioned, the
centrally disposed blowout coils 15, 16 are connected together in
series, this being effected as by a connection 17 at the top of the
coils (Figs 1 and 3), and the other lower ends 18, 19 of the blowout
coils 16 15 respectively are secured to the transfer arc horns 10, 11

respectively, as shown more -clearly in Fig I of the drawings.
Because of the reactance of the blowout coils 15, 16 it is difficult
to force current to flow through them because of the countervoltage
set up in the coils The transfer arc-extinguishing means 13 is
therefore, desirable to assist in this transfer into series circuit of
the blowout coils 15, 16 by extinguishing the arc portion 8 b
Generally, the transfer arc-extinguishing means 13 includes a
plurality of spaced insulating plates 21, the configuration of which
is more t O clearly shown in Fig 5 of the drawings It will be noted
that each insulating plate 21 has a slot 22 provided therein which
tapers inwardly to one side of the center line 23 of the plate The
plates 21 are spaced laterally apart by asbestos rope spacers 21 a as
more clearly shown in Fig 2 of the drawings Adjacent plates 21 may be
positioned oppositely so that the slots 22 are alternately on opposite
sides of the center line of the plates and provide a zigzag path for
the arc 70 Referring to Fig 1 it will be noted that a plurality of the
plates 21 are disposed between the arc horns 10, 11 and a single-turn
shading coil 25 The shading coil 25 in turn encircles the core or yoke
portion 26 which 75 magnetically interconnects the Pole plate portions
27, more clearly shown in Fig 2 of the drawings.
Referring more specifically to Fig 7 of the drawings, it will be noted
that the arc 80 portion or section 8 b moves upwardly to strike the
lower end 28 of the shading coil to establish two serially related
arcs 29.
which are electrically in series These arcs move upwardly within the
slots 22 of 85 the insulating transfer plates 21 to become
extinguished.
Following extinction of the arc portion Sb within the transfer
arc-extineuishing means 13, the blowout coils 15 and 16 are seriall 90
connected into the circuit, and the enercization of these coils 15 16
sets up a magnetic flux within the magnetic circuit 24 which includes
the pair of side magnetic pole plates 27 and the interconnecting yoke
26 Pre 95 ferably, the pole plates 27 are formed of vertically
extending sheets of a suitable magnetic material to form a laminated
structure.
more clearly shown in Fig 2 of the drawings Magnetically
interconnecting ihe side 100 pole plates 27 is the central
interconnecting core or yoke portion 26, about which encircles the two
serially related blowout coils and 16.
As will be obvious to those skilled in the 105 art, the H-type of
magnetic circuit 24 shown, upon the energization thereof, causes
magnetic flux to flow between the pole plates 27 in the manner
indicated by the arrows 20 in Fig 2 This magnetic flux extending 110
transversely between the pole plates 27 causes upward movement of the

arc portions 8 a, 8 c into the arc-extinguishing sections 4.
of the arc-chute structure 3.
The left hand end of the arc portion 8 a 115 as viewed in Fig 1,
quickly transfers to the outer arc horn 12, the lower end of which is
connected, as shown, to the movable arcing contact 7 and hence to the
lower terminal L 2 of the device Also the right hand 120 end of the
arc portion 8 c quickly transfers to the right hand arc horn 9 of the
device.
which is electrically connected to the stationary contact 6 by the
connection 9 a and hence to the upper terminal LI of the inter 125
rupter.
The current path through the interrupter (as viewed in Fig 1) may then
be traced, beginning at line LI, through connection 9 a.

hlald miain extinguigliilg wition i to the transfer arc horn or plate

the connection 17 at its upper t( end of the rear blowout coil 16,

plate or horn 10, through the e arc in main left hand extinguishing
section t 4 to the arc terminal plate or horn 12 and s thence to line
L 2.
Disposed within each of the arc-extin a guishing sections 4, 5 is a
plurality of spaced, a slotted, ceramic plates 40, the configuration v
of which is more clearly shown in Fig 4 of the drawings As shown, each
ceramic d Mate 40 has a slot 41 provided therein, the upper closed end
42 of which is slightly offcenter The plates 40 are staggered during
assembly so as to form a horizontally disposed, zigzag arc passage 43
throughout the length of the arc-chute sections 4, 5 which quickly
brings about extinction of the arc portions 8 a, 8 c The plates 40 are
spaced laterally apart, as shown more clearly in Fig 2, by sections of
asbestos rope 44 cemented between the plates 40 adjacent the outer
edges thereof, the method being identical to that previously referred
to in spacing apart the insulating plates 21 of the transfer
arc-extinguishing means 13.
Proper operation of the transfer arc extinguishing means 13 is
necessary to ensure rapid blowout-coil transfer, and it is an
important aspect of the invention to provide a more effective transfer
arc-extinguishing means 13, while at the same time providing a more
compact and effective structure It was found that with relatively
short transfer arc-extinguishing plates below the yoke the -40
transfer arc portion 8 b extending between the transfer arc horns 10,
11 sometimes flashed over across the top of such short transfer
arc-extinguishing plates and prevented the blowout coils 15, 16 being
inserted into series circuit.

It has been found that by making the yoke portion 26 somewhat longer
and narrower than previous constructions of this type, yet having the
same cross-sectional area, there was adequate space on both sides of
the shading coil 25 for the relatively long transfer arc-extinguishing
plates 21.
This is all obtained without increasing the overall size of the arc
chute 3 As shown in Fig 7, with this arrangement the transfer stack is
made of substantially full length plates 21 and divided into two
sections 31, 32 and placed in the spaces between the transfer horns
10, 11 and the shading coil 6025 The transfer arc 8 b divides into two
sections 29, 30 with the shading coil 25 forming a common terminal
between them.
This change accomplishes a number of desirable results Whereas
formerly an arc t 5 to the shading coil shorted out the transfer "stk
and resulted in uncatiffictory perfoiilrce, in the present arrangement
the arc is -.ill confined to the stack Also, the ability ) use longer
plates 21 in the transfer stack ermits the use of a more efficient
slot shape 70 rd the length of the plates 21 beyond the nds of the
slots 22 eliminates the tendency tward flashing over the top of the
transfer tack.
Aside from improving transfer perform 75 Lnce, this new construction
results in two additional distinct improvements First, it vill be seen
that the transfer arc-extinguishng means 13 is not disposed so close
to the contact structure 2 which results in ade 80 luate space being
available for a desired nitial looping effect of the arc Thus, the arc
8 is able to get away faster from the contact structure 2 resulting in
less ionization in the region of the contact structure 85 2, which
reduces the tendency to restrike.
Secondly, by disposing the transfer plates 21 above the fire plates
33, the latter need not be grooved to support plates below the shading
coil 25, which was used in con 9 G structions heretofore The strength
of the fire plates 33 is, consequently considerably improved,
resulting in a stronger structure.
To support the coils 15, 16 rigidly within the apertures 34 disposed
in the insulating 95 arc chute jacket 35, coil washers or plates 36 of
insulating material are employed surrounding the yoke 26 and
maintained separated by the shading coil 25, as more clearly shown in
Fig 2 100 Also, an insulating spacer plate 38 is preferably utilized
between the pole plate portions 27 and the blowout coils 13 14 for
insulation purposes.
It will be noted that there is an open 105 space indicated at "A" in
Fig 7 This space may be left open, as shown, so that the initial arc
portion 8 b may move rapidly upwardly within this space "A" to contact
the lower end 28 of the shading coil 25 resulting 110 in the two arc

portions 29, 30, the extinction of which occurs in the manner
heretofore described However, for certain applications, it may be
desirable to interpose within the space "A" additional insulating 115
plates of shorter length to assist in the extinction of the arc 8 b,
particularly during low current values and the present invention is
intended to cover such a modification.
For higher current values, the central por 120 tion of the arc 8 b
would move through such shorter plates, contacting the shading coil
and being extinguished in the manner as set forth above.
The foregoing construction has been ex 125 perimentally tested in the
laboratory, and has been found to give greatly improved results over
prior constructions in which relatively short transfer
arc-extinguishing plates were utilized Thus, the use of long 130
785,957 transfer plates 21 having mnore suitable slot configuration
greatly speeds up interruption of the transfer arc 8 b, thereby
rapidly inserting the series blowout coils 15 16 into the circuit to
quickly set up the desired magnetic field within the arc chute

Improvements relating to Motor Vehicles We, DAIMLER-BENZ
AKTIENGESELLSHAFT, of Stuttgart-Untertiirkheim, Germany, a Company
organised under the laws of Germany, do hereby declare the invention,
for which we pray that a patent may be granted to us, and the method
by which it is to be performed, to be particularly described in and by
the following statement: -
This invention concerns motor vehicles, particularly large vehicles
such as omnibuses, coaches and the like It relates to improvements
upon or modifications of the invention claimed in our Patent No
746,169.
According to claim 1 of that Patent, on the one hand, a rigid front
axle sprung by helical springs or similar non-guiding springs is
abutted against the frame by a triangular stay system so as to be
capable of pivoting in all directions and by a separate transverse
abutment device, for example a transverse link, for the purpose of
taking up transverse forces and, on the other hand, a rigid rear axle
is guided and sprung in relation to the frame by longitudinally
extending leaf springs.
As described and illustrated in the Specification of the above Patent,
the steering gear is disposed outside the vertical transverse plane
containing the axis of swinging of the stay system For the purpose of
obtaining correct steering geometry, the steering gear is arranged to
actuate through a link an intermediate lever which is mounted
approximately in the said transverse plane so as to rock about an axis

extending transversely of the direction of travel and is in turn
connected to a steering arm at the front axle by a link performing
substantially the same swinging movement as the stay system Such
mechanism is, however, not suitable for all vehicle constructions,
because the lever occupies relatively considerable space in the
vertical direction The present invention seeks to obviate this
disadvantage.
According to the invention, in a motor vehicle as claimed in claim 1
of Patent No.
746,169 and comprising steering gear disposed outside the vertical
plane containing the transverse horizontal axis of swinging of the
stay system by which the front axle is abutted lPice 3 s 6 d l against
the frame, the said axis is located between the steering gear and the
front axle and steering linkage connecting the said gear to the wheels
on the said axle includes an intermediate lever which is located
approximately in the said plane, is mounted so as to be rockable about
an approximately vertical axis on the sprung part of the vehicle and
is connected by a link directly to the steering arm of one of the said
wheels in such a manner that the said link does not cross the axle The
linkage can then be made relatively flat, so that it can be
satisfactorily accommodated even when there is little space available
vertically.
The steering geometry is substantially unimpaired by the vertical
disposition of the lever axis.
One embodiment of the invention by way of example is shown
diagrammatically and in perspective in the accompanying drawing.
The front wheels 10 of a motor vehicle are supported by an axle 11 by
means of steering pivots 12 The axle 11 is resiliently abutted by coil
springs 13, against a transverse member 14 and is connected to the
said member by a transverse link or stay 15 At points 16, the member
14 is connected possibly with the inter-position of rubber cushions
(not shown) to the main frame of the vehicle, which may be combined
with the body, in such a manner that the member 14 together with the
axle 11, the wheels 10 and the springing 13 ' can be removed as a unit
from the frame.
The axle 11 is abutted against the frame so as to be capable of
pivoting in all directions For this purpose, the triangular stay
system 17 is connected to a bracket 1 '8 on the frame by a joint,
incorporating rubber cushions or the like, which permits movement in
all directions On vertical deflection of the wheels, the axle 11
swings about the horizontal transverse axis x-x.
The steering wheel 19 transmits steering movement through steering
gear 20 to a drop arm 21 ' connected by a link 22 to one arm of an
intermediate lever 23 which is supported from the frame so as to be

rockable about a vertical axis 24.
The axis 24; is disposed in the vertical transverse plane of the
vehicle which contains the transverse axis x-x of swinging for the
stay system 17 The other arm of the lever 23 is connected by a further
link 25 to a steering arm 26 connected to the steering pivot 12.
A track rod 27 connects together the steering arms of the two opposite
wheels.
When the axle 11 deflects about the axis x-x, the rod 25 performs a
swinging movement which corresponds substantially to that of the stay
system 17, so that the steering is not unduly and undesirably affected
by sprung movements of the wheels.
The rear axle (not shown) of the vehicle will be guided and sprung in
the manner described and illustrated in Patent No 746,169.
In the above described arrangement, it will be seen that the steering
gear 20 is disposed outside of the vertical plane containing the axis
x-x, which is located between the said gear and the front axle 11 The
intermediate lever 23 is located approximately in the said plane and
is mounted on the sprung part of the vehicle so as to be rockable
about an approximately vertical axis The lever 23 is directly
connected by a link 25 to the steering arm 26 The link 25, does not
cross the axle 11.
