  • Patent number: 7614140
    Abstract: An apparatus includes a cartridge for storing C-clips. The cartridge includes two lateral members and a lower member extending between the lateral members. The lateral members extend beyond the lower member by at least the thickness of the C-clips so that first one of the C-clips can be moved past the lower member. A saddle is movably connected with the lower member for carrying some of the C-clips. The saddle includes a slope for contact with the first one of the C-clip. Thus, the saddle is moved as the first one of the C-clips is moved. A pocket is connected with the cartridge below the saddle for receiving a pin. A pusher is put movably in the cartridge for pushing the C-clips. An elastic element biases the pusher. A shell receives the cartridge. A hammering device forces the first C-clip onto the pin against the slope.
