Abstract

175,328. Adams, G. R. Oct. 1, 1920. Boring-bar machines.-In a machine for boring internal-combustion engine cylinders, the boring- bar is worm-driven at 8, Fig. 2, and drives a feathered plate-cam 14, Fig. 4, which rocks a link 18 thereby intermittingly engaging a pawl with a ratchet-toothed feed-nut 22, the latter being mounted on the threaded portion of the bar and adapted normally to rotate with it. The push-rod 19, Fig. 3, is adjustable in the link 18 for varying the feed-intervals and carries a stop 27a engaging a slot in the pawl 20, which is normally held in engagement with the feed-nut by means of a spring 27. The halves of the divided feed-nut 22, Fig. 5, are held together by a garterspring 29. The boring-bar is balanced by a hanging weight 50, Fig. 2, and is returned to lifted position by a hand-crank 49 and pinion and rack 48, 47, after the feed-nut segments have been removed.
