ABSTRACT:
A motorized wire-drawing machine for manufacturing precious metal wire. A clasp plate is slidably supported by two support rods extending from the draw plate support block to a motor support block. Mounted parallel to the support rods and passing through a threaded hole in the clasp plate with threads matching the threaded rod is a threaded rod. Thus, when the threaded rod is rotated, the clasp plate moves longitudinally on the support rods and the threaded rod. The threaded rod passes through a hole in the motor support block to a motor drive shaft, connected to the shaft by means of an adjustable shaft that drives the threaded rod under normal resistive load from the wire but slides, disengaging the motor from the threaded rod, during high resistive loads. The clutch is adjustable to accommodate wire of various sizes and materials.
