Abstract

8109. Alexander, G. H. March 31. Boring - bar machines. - Multiple - spindle machines are constructed to permit adjustment to a small spindle pitch. The spindle brackets b, adjustable laterally on the bed by handoperated rack-and-pinion mechanism, overlap as shown, are steadied by a bridge d, and contain separate gear trains driven from a common worm shaft j. The work table q is traversed by a screw r driven at s from a worm through reducing-gear and a clutch x connected to an automatic stop-mechanism actuated by a dog 7 on the table. Hand-traverse is provided by a wheel y and gearing z, 2, 3.
