Machine for threading fasteners into workpieces

摘要

Hanger bolts are delivered one-by-one from a hopper and each is picked up by a reciprocating holder which shifts the bolt laterally and broadwise into alinement with a power-rotated chuck. The bolt then is pushed endwise into the chuck by a furniture leg and is threaded into the leg as an incident to being turned about its own axis by the chuck. A shelf, a gate and an escapement coact to effect delivery of the bolts from the hopper to the holder in timed relation with the reciprocation of the holder.
