Title: Improvements in Pawl and Ratchet Gearing.
Inventor: BENNITT WILLIAM BRABINER
IPC: G05G5/02
Filed: 1916-03-04
Abstract: 102,195. Bennitt, W. B. March 4, 1916. Controllers, actuating-mechanism for.-A shaft for operating electric motor controllers, circular dial switches, &c., is rotated in a series of steps by ratchet gearing, stops being provided to prevent rotation beyond definite positions which are different for each tooth of the ratchet, so that the position of the operating-handle will show through how many steps the shaft has been rotated. Fig. 1 shows an arrangement with two pawls and sets of teeth for rotating the shaft in either direction. The pawls 17, 18 are carried by the handle 13, and the teeth 3, 4, 7, 8 by the shaft to be rotated. The teeth in each set are placed in succession nearer to the axis of rotation. On moving the handle 13 to the left, the pawl 18 engages the outermost tooth 42 and rotates the shaft until a projection on the pawl meets a fixed stop 34. The handle is then retracted until the pawl engages the next tooth 7. A fixed cam 43 engaged by a projection on the back of the pawl prevents the engagement of any other tooth in the series. On again moving the handle to the left, the pawl 18, being nearer the axis of the shaft, misses the stop 34 and engages the stop 35, rotating the shaft through another step. Subsequent steps are affected in a similar manner. During these movements, the pawl 17 is held out of contact with the teeth 3, 4 by a fixed cam 26 engaged by a projection 21. Similar cams and stops 45, 30, 31 enable the shaft to be rotated in the opposite direction by the pawl 17. The shaft is returned to its zero position by shoulders 15, 16 moved by the handle to engage a projection 41 on the plate carrying the ratchet teeth. Stops 38, 39 limit the movement of the handle.
