Abstract

412,076. Variable - speed ratchet gearing. HURTH, C., HURTH, H., HURTH, F., HURTH, L., and SCHIEFELBEIN, D., (trading as HURTH MASCHINENFABRIK, C.), 19, Holzstrasse, Munich, Germany. Sept. 28, 1933, No. 26759. Convention date, Nov. 4, 1932. [Class 80 (ii).] Variable-speed ratchet gearing applicable to the feed mechanism of a milling machine comprises a slotted lever working on a slidable pivot for varying the throw of the lever, the pivot being stationary during working. A constantly rotating shaft 2, carries an eccentric 3 which reciprocates an arm 4 pinned to the end of a lever 5. The latter pivots about a pin 12 mounted on a rack and pinion operated slide and moves, through a connecting link 9 pivoted at 8, the pawl 10 of a ratchet feed wheel 1 fixed to a screw spindle.
