Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
184 words
In a broaching machine having a fixture holding device adapted for movement along a longitudinal path into a broaching machine and a hopper having a supply of said fixtures spaced from the broaching machine, the improvement of a device for use in transferring said fixtures from said hopper to said fixture holding device, comprising dual supports in spaced apart relation, each of said supports having receptive bushings; a hub mounted between said supports, said hub having extensional shafts each of which is rotatably mountEd in one of said bushings; disks mounted in spaced apart relation on said hub, each of said disks having a peripherally receptical in alignment with one another, both of said recepticals adapted for receptive engagement of a fixture from said hopper; cam actuated mechanical means for holding a fixture in said receptical; means for providing rotary motion to said hub in order to place said latter fixture in position for engagement by said fixture holding device, and means associated with the fixture holding device for releasing the fixture from said receptical, and securing the fixture in the fixture holding device.
