A primer feed mechanism mounted on a carrier of an artillery piece includes a body assembly for mounting the primer feed mechanism on the carrier, the body assembly having guide rails and a follower plate; a tray assembly that is movable on the guide rails of the body assembly, the tray assembly including a housing and an injector arm assembly; an actuator drive link connected to the carrier; a quick release link connected to the actuator drive link; and a drive link assembly connected to the quick release link and to the injector arm assembly; wherein one end of the injector arm assembly includes a push pin that reciprocates in the housing to inject a primer and another end of the injector arm assembly includes a follower that travels in the follower plate of the body assembly.

Automatic primer feed mechanism

A remote firing mechanism enables an operator to fire a weapon remotely, from a position other than from behind the breech, in order to minimize firing hazards to the operator. The remote firing mechanism is secured to a carrier assembly mounted on, or near the breech, for enabling an operator to fire the weapon from the right side of the weapon. The carrier assembly includes a connector secured to a linkage mechanism of the remote firing mechanism. In turn, the linkage mechanism is connected to a lanyard that enables the operator to initiate the firing operation. The linkage mechanism and the lanyard are positioned remotely from the breech.

Remote firing mechanism to enable firing remotely from a weapon breech

A safety latch assembly locks a firing tray mechanism and prevents it from firing a primer prematurely if a breech is not safely closed. The safety latch assembly includes a latch body, a latch hook for locking a firing mechanism tray, and a shaft that connects the latch body to a housing. A torsion spring is secured to the shaft, to bias a first pin towards the firing mechanism tray. A second pin couples a circular rack to the firing mechanism tray.

Safety latch assembly for use in a weapon breech

An automatic primer feed mechanism for use with a carrier assembly of a large caliber artillery piece, which includes mechanical assemblies for automatic primer loading after full breech closure and allows for spent primer cartridges to be extracted before opening of the breech to maximize safety, thereby allowing the gun crew to perform artillery piece misfire, sticker and check fire operations before the breech is opened. The mechanism includes a body member that mounts the automatic feed mechanism to the carrier of the artillery piece so as to interface with the carrier to position the mechanism on one side of the breech of the artillery piece. The body member includes a cam surface member, which provides a path for movement of an injection arm member. The tray member has guide rails for engagement with the body, which slides in relation thereto. A magazine containing a plurality of primer cartridges, which inserts in a receiver channel located in the tray member. The mechanism provides improved safety wherein live primers stored in a magazine are at a distance from the firing chamber hole that prevents flame from reaching a live charge before a fresh primer is injected therein.
