AUTOMATIC PRIMER FEED MECHANISM

摘要

An automatic primer feed mechanism (20) for use with a carrier assembly (10) of a large caliber artillery piece, which includes mechanical assemblies for automatic primer loading after full breech closure and allows for spent prjimer 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 (20) includes a body member (23) that mounts the automatic feed mechanism (20) to the carrier (10) 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 (23) includes a cam surface member (22), which provides a path for movement of an injection arm member (24). The tray member (21) has guide rails for engagement with the body, which slides in relation thereto.
