An electrical make-break connection for an apparatus having a recoiling portion and a non-recoiling portion may include a non-recoiling assembly fixed to the non-recoiling portion and a recoiling assembly fixed to the recoiling portion. Each of the non-recoiling and recoiling assemblies may include a mounting bracket and an electrical contact assembly disposed in the mounting bracket. Each contact assembly may include one or more electrical conductors. The non-recoiling contact assembly may float in its mounting bracket. Part of the mating surface of the recoiling contact assembly may be more elastic than part of the mating surface of the non-recoiling contact assembly. Elastic deformation of the recoiling mating surface by the non-recoiling mating surface may provide a fluid seal for the make-break connection.

Fluid-isolating, self-aligning make-break electrical connection

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

An out-of-battery lock for a primer feed mechanism having a drive shaft and a drive shaft housing surrounding the drive shaft, the out-of-battery lock including a housing having an opening therethrough for attachment to the drive shaft; a pair of wings disposed on opposite sides of the housing; a plunger slot formed in the housing; a plunger movably disposed in the plunger slot, the plunger including a central bore therein and a pair of tabs disposed on opposite sides of the plunger; and a compression spring disposed in the central bore in the plunger, the compression spring providing a force to bias the plunger towards the drive shaft housing.

Out-of-battery lock for automatic primer feed mechanism

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.
