Abstract
Apparatus is disclosed for interconnection of threaded members such as nuts and bolts. Components can be used in combination whereby nuts and bolts are automatically supplied, properly aligned, and threaded together for rapid assembly on parts having preformed openings for the bolts.
Claims17
An apparatus for assembling a first member having a central channel with internal threads and a second member having a shank with external threads, by interconnection of the threads, said apparatus comprising:
- a. a thrust rod having a longitudinal axis, said rod being rotatable and moveable back and forth on said axis yet stabilized against lateral movement with respect thereto,
- b. holding means mounted on one end of said thrust rod, said holding means having a gripping end that meshes with said first member,
- c. a spindle which extends through said holding means and through said first member enmeshed by said gripping end of the holding means, said spindle having an outermost tip which contacts said second member and which retracts through said first member upon interconnection of the two members by means of their threads, and
- d. thrusting means whereby said shank of the second member is urged axially toward said central opening of the first member.

Apparatus for assembling threaded nuts on threaded bolts which comprises:
- a. a first magazine for holding a supply of nuts,
- b. a second magazine for holding a supply of bolts,
- c. a nut holding means having an axially retractable, outwardly projecting nut spindle,
- d. a bolt thrusting means for driving bolts out of the second magazine and toward an outermost tip on said spindle, and
- e. a thrust rod that is both rotatable and moveable back and forth on its longitudinal axis for conveying said spindle axially through the central opening of a nut held in the first magazine, for conveying said holding means into engagement with said nut, and for screwing said nut onto a bolt driven from said second magazine by said bolt thrusting means.
