Claims
- 1. A cartridge for storing fasteners from which fasteners are obtained and fed to a fastener installation tool, comprising:
- an elongated cartridge body, having an internal opening which extends along the length thereof, the opening having dimensions slightly greater than the dimensions of the fastener;
- an opening at the lower end of the cartridge body for exit and entry of fasteners; and
- a latch connected to the cartridge body and having a bias action tending to move the latch to a first position relative to the cartridge body, the latch being movable between the first position and a second position, wherein in the first position, the latch includes a portion thereof which extends over the opening at the bottom of the cartridge, preventing fasteners from moving through the opening and wherein, when the latch is forced away from the first position against the bias to the second position, the portion of the latch is moved relatively away from the opening, permitting fasteners to move therethrough.
- 2. A cartridge of claim 1, including a mounting element located near the bottom of the cartridge, adapted to cooperate with a clamp for the cartridge mounted such that when the clamp is holding the cartridge in place, a portion of the clamp moves against the latch, forcing the latch from its first position to its second position.
- 3. A cartridge of claim 1, including means for maintaining the relative orientation of the fasteners during entry and exit of fasteners from the cartridge.
- 4. A cartridge of claim 1, including a magnet positioned at the lower end of the cartridge adjacent the internal opening and a follower element which rides on top of the uppermost fastener in the cartridge, moving downwardly as the fasteners move from the cartridge means, maintaining time fasteners in proper relationship, wherein the magnet captures the follower element when the follower element comes into proximity with the magnet, preventing the follower element from moving through the opening at the lower end of the cartridge.
