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 patent describes a cartridge strip advancing mechanism for a powder driven fastening tool. The mechanism uses a trigger that is movable between a first and second position to actuate both a firing mechanism and to automatically index a strip of explosive powder cartridges. An advancing lever, with a strip engagement portion that extends into the tool's magazine channel, is pivotally coupled to the tool. An advance link is cammingly engaged with the advancing lever and is operationally associated with the trigger such that the strip engagement portion has a first position in the channel when the trigger is in the first position, and a second position when the trigger is in the second position. This allows the trigger motion to automatically advance the cartridge strip without requiring additional operator

This patent describes an improved double action hammer trigger mechanism for firearms. It includes a transfer bar connected to the trigger that performs two functions. First, it engages a sear pin to pivot the sear and release a cocked hammer for single action firing. Second, it engages a pin on the hammer to initially draw the hammer back against a spring as the trigger is pulled, before moving to release the hammer to fire for double action operation. This allows the mechanism to provide both single action and double action firing modes using a simplified design compared to prior 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 rifle with two safety mechanisms. It has a barrel containing a striker that is spring-loaded and fired by a firing mechanism. The first safety is a manual bolt lever that can retract the striker and lock it in a non-firing position. The second is an automatic firing mechanism that retains the striker and needs to be activated externally to allow firing. When loaded, this mechanism keeps the rifle from discharging unless a safety catch is moved to the firing position. The rifle thus has both a manual and automatic safety to prevent accidental firing.

The document discloses a powder driven fastener setting tool with an improved magazine strip indexing mechanism. It contains a lever cam coupled to a reciprocating sleeve of the tool's firing mechanism. An indexing lever is pivotally mounted to the tool and has a magazine engagement portion that extends into the tool's magazine channel. The indexing lever also has a cam follower portion engaged with the lever cam. As the sleeve reciprocates between first and second positions, the lever cam causes the indexing lever to move its magazine engagement portion between different positions in the magazine channel. This movement indexes the magazine strip forward through the channel with each operation of the tool.

This document is a patent application for a pistol with a firing mechanism that can be easily adapted to operate in different modes. It describes a basic pistol design that functions in a double-action only (DAO) mode. The firing mechanism can be modified slightly to enable single-action (SA) or double-action/single-action (DA/SA) modes of operation. The application contains detailed drawings and descriptions of the components of the firing mechanism and how they interact for DAO, SA, and DA/SA modes. The goal is to provide a modular pistol design that reduces production costs by enabling different operation modes using a common basic design and components.

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 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.

This document describes a patent for a target firearm with a blowback breech bolt mechanism and safety latch. It consists of a frame with a barrel mounted at the front and a tubular receiver at the back. A recoil spring operated breech bolt moves between a forward firing position and rearward loading positions. A safety latch holds the breech bolt in the loading position, while a trigger actuated sear holds it in the cocked position. The design uses few parts and allows for quick reloading without manually opening the chamber.
Deadfalls and Snares
This document provides instructions for building various types of deadfall traps using locally available materials like saplings, poles, rocks, and stakes. It describes the basic pole deadfall, emphasizing the importance of a small animal pen, trigger system, and use of bait. Additional deadfall designs are presented for small animals. Trappers are advised to carefully construct pens, cover traps with natural materials, and consider weighting falls for smaller saplings. Deadfalls are praised for requiring no investment, avoiding injury to fur, and killing animals quickly and quietly.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
