Abstract
190,708. Makarewiez, M. Dec. 20, 1921, [Convention date]. Boring-bar machines.-An apparatus for boring the ccnnecting-rods and bearings of internal combustion engines comprises a frame which holds the rod or bearing and also carries a hand-operated boring-bar. The frame a is provided with adjustable cones v, x, which engage the small end of the connecting-rod and are carried in a longitudinal slot in the frame, setting being facilitated by a scale 1. The other end of the rod is secured by clamping screws t. The boring-bar b, driven by a hand-wheel, carries a tool r radially adjustable by means of a screw p having a graduated head, and is fed longitudinally by a differential gear ccmprising a pinion slidably keyed to the bar engaging a larger pinion d which carries with it a pinion e gearing with a larger pinion attached to a nut h on the bar. The nut is split for effecting withdrawal of the bar. When boring bearings, the cones and clamping screws are removed and the bearing is held in the square to the longitudinal slot in the frame by screws d, d<1>.
