Abstract
763,855. Counting-apparatus. SPERRY GYROSCOPE CO., Ltd. June 8, 1955 [June 8, 1954], No. 16827/54. Class 106 (1). A revolution counter comprises a first-order indicating disc 1 driven by a pinion 4 through gearing 5-10 and a second order indicating disc 3 driven by continuous transfer mechanism 13, 14, 15, 16 from the shaft 12 of the first order disc 1. Integral with the disc 1 is a snail cam 22 which co-operates with one arm 25 of a bellcrank lever 24, the other arm 23 of which is connected by a pin-and-slot connection 26, 28 with a cursor member 21, 27. The arrangement is such that during substantially a complete revolution of the disc 1 the cursor 21, 27 moves with the appropriate graduation of the disc 3 and at the end of the revolution-when the arm 25 moves along the steep incline of the cam 22 the cursor is moved suddenly in the appropriate direction to the succeeding graduation on the disc 3. Incorrect reading of the counter is therefore avoided. The counter may comprise more than two orders and the discs may be replaced by drums. Re-setting of the discs 1, 3 is effected by rotating knob 19.
