Abstract
Abstract A device for automatically presenting fasteners in a predetermined disposition comprising a container for the fasteners which presents the fasteners to a rotary drum which raises the fasteners upwardly for deposit into a chute. The fasteners are fed down the chute to a ramp which positions individual fasteners in a predesired position in a feed barrel for receipt by a fastener tool. An escapement mechanism is positioned between the chute and the ramp so that a single fastener at one time falls down the ramp into the feed barrel.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
140 words
A device for automatically positioning a fastener in a predetermined, desired disposition and automatically inserting the fastener into an application tool comprising: a. support means; b. a housing mounted on said support means for receiving a bulk quantity of fasteners; c. a vertically disposed rotary drum adapted to receive fasteners from said housing and having means to transport the fasteners upwardly during rotation of said drum; d. platform means carried on said support means and adapted to receive fasteners from said transport means; e. chute means coacting with said platform means and adapted to transport the fastener; f. a ramp means for receiving the fastener from said chute means and placing the fastener in a predetermined, desired disposition in a feed barrel; and g. drive means coacting with said feed barrel to automatically insert the fastener into the application tool.
Claim 2
Independent Claim
140 words
A device for automatically positioning a fastener in a predetermined, desired disposition and automatically inserting the fastener into an application tool comprising: a. support means; b. a housing mounted on said support means for receiving a bulk quantity of fasteners; c. a vertically disposed rotary drum adapted to receive fasteners from said housing and having means to transport the fasteners upwardly during rotation of said drum; d. platform means carried on said support means and adapted to receive fasteners from said transport means; e. chute means coacting with said platform means and adapted to transport the fastener; f. a ramp means for receiving the fastener from said chute means and placing the fastener in a predetermined, desired disposition in a feed barrel; and g. drive means coacting with said feed barrel to automatically insert the fastener into the application tool.
