摘要:
A hammer for a portable firearm, such as automatic pistol, which hammer is at least partially exposed and has a hammer piece (1), arranged for firing a bullet cartridge by striking action and an end piece (2) extending a given distance for facilitating grasping of the hammer piece and preferably connected to the hammer piece (1) in a flexible manner, where either the end piece (2), extends a given distance on the hammer piece (1), is mounted via a flexible connection, or the end piece (2) is made of a flexible material.
摘要:
An automatic pistol, with at least a barrel (1) and a slide (2) that move relative to the rest of the firearm and to each other, whereby the barrel extends through an alignment channel (3) in the slide. The weapon included means (4) of centering the barrel around at least one axis through the slide such that the barrel will not jam. The means are elastic and resilient and rest lightly against the inner surface of the channel before the weapon is discharged.

Safety devices for use with a handheld firearm are disclosed. The safety devices include a lever that can be pivoted into the travel path of the hammer of the firearm to preclude the hammer from striking a firing pin. In an example, the lever is connected to the trigger such that the safety device is released when the trigger is pulled. In another example, the lever protrudes into the magazine shaft of the firearm such that the safety device is only released when a magazine is inserted into the shaft.

Slides and methods for finishing a lock surface of a slide in a firearm are disclosed. A disclosed method of finishing a lock surface comprising a rearward facing wall adjacent an ejection window of a slide of an automatic firearm includes: (a) pointing a laser at at least one of the lock surface and a material surface bordering the lock surface; and (b) heating the at least one of the lock surface and the material surface bordering the lock surface with a laser beam to harden the lock surface.

An unlocked self-loading pistol and a conversion kit for modifying a locked self-loading pistol adapted for firing normal and powerful cartridges into an unlocked self-loading pistol capable of firing weak cartridges as well as normal and powerful cartridges is disclosed. The unlocked self-loading pistol includes a return spring which is closely surrounded on the outside by a sleeve composed of an elastomer material. The length of the elastomer sleeve corresponds approximately to the length of the compressed return spring. The sleeve absorbs a part of the movement energy of the breech and passes it on into the grip. The conversion kit can be used to convert a locked self-loading pistol into an unlocked self-loading pistol as stated above and vice versa. The disclosed conversion kit includes: an alternate barrel which does not come into locked engagement with the breech, the abovementioned elastomer sleeve, and, optionally, a substitute return spring. The locked self-loading pistol and the conversion kit together form a weapon system which can be used to assemble a locked self-loading pistol or an unlocked self-loading pistol, as desired. The unlocked self-loading pistol can fire very lightly filled ammunition and normally filled ammunition without malfunction, and additionally ensures that the breech will withstand the firing of heavily filled ammunition.

The invention discloses a hand-held firearm with a barrel assembly (2, 18, 36, & 54) moving back and forth essentially in or opposite the direction the weapon is fired in between a forward and a rear stop (44, 48, & 50) on or in a frame or grip assembly (12). A breech assembly (6 & 32) that moves back and forth essentially in the same direction as the barrel assembly between a forward and closed position and a rear and open position, moving out of the closed position and into the open position against the force of a closure spring (16) and, at the end of its return stroke, the frame or grip assembly or a component (64 or 64') resting off it. A buffering spring (66) tensions the barrel assembly toward the forward stop (44 or 50) and buffers its contact with the rear stop (44 or 48). The closure spring (16) and the buffering spring (66) are correlated to ensure that the breech assembly will strike the frame or grip assembly or the component supported off it essentially at the instant the barrel assembly comes into contact with the forward stop.
摘要:
A firearm is described which has a trigger mechanism, a cock and a cocking actuator that is separate from the cock. A striker spring acts on the cocking actuator to drive the cock. A cocking actuator safety mechanism, which is independent of the trigger mechanism, is provided for securing the cocking actuator in its cocked position. The illustrated safety mechanism has an operating handle which sits next to the lug of the cock, so that the safety mechanism can optionally be operated together with the cock.
摘要:
A gas-pressure loading arrangement for a self-loading rifle includes a gas cylinder fluidly connected to the bore of the rifle barrel and a gas piston received in the gas cylinder to define a gas chamber. The gas piston has piston ring members seated thereon in engagement with the inner surface of the gas cylinder under tension. The piston ring members allow the gas piston to be loosely received in the gas cylinder while preventing gas leakage around the piston. The piston ring members also scrape gas deposits off the inner wall of the gas cylinder during piston movement so that the inner wall remains clean.
