Double pedal arrangement for reciprocating machine tool control

The speed of movement of a drive is determined by the position of two pedals (1,2) rigidly coupled together so as to move in opposite directions. The lever (3) connecting the pedals together is spring-biased (9, 10) against two widely spaced pivot points (11, 12) where electrical contacts determine...

Zusammenfassung:	The speed of movement of a drive is determined by the position of two pedals (1,2) rigidly coupled together so as to move in opposite directions. The lever (3) connecting the pedals together is spring-biased (9, 10) against two widely spaced pivot points (11, 12) where electrical contacts determine the direction of tilt. An e.g. inductive sensor (14) midway between the pivots detects the variation in position of the lever, and controls a stepless hydrostatic or electrohydraulic drive. A brake is applied by pressure on a treadle (16) between the pedals.
