Abstract

Abstract A device for driving anchoring members is formed of a casing containing a barrel axially movable within the casing and having an axially extending bore. A grip member is secured to the casing and forms a duct communicating with a cartridge chamber in the rear end of the barrel. A cartridge magazine is positioned within the duct and means are arranged within the casing and the grip member for moving cartridges in the magazine into alignment with the cartridge chamber in the end of the barrel. By moving the barrel axially rearwardly the cartridges are loaded into the cartridge chamber.

Claim 6
Dependent Claim 59 words
A device, as set forth in claim 4, wherein an ejector member is positioned on the rearward end of said hammer piston in axial alignment with the cartridge member in said barrel and is arranged for ejecting spent cartridges from the cartridge chamber when said hammer piston is displaced to the rearward end of said barrel by said lever.
Claim 7
Dependent Claim 94 words
