Abstract

1,271,010. Cams. HONEYWELL Ltd. 2 Dec., 1970 [30 Dec., 1969], No. 63273/69. Heading F2K. [Also in Division H1] A cam assembly for operating switch contacts through cam followers comprises a stack of discs 30 each provided with three equally spaced conical projections 36 on one side and corresponding recesses or holes on the other. Each disc has a central hole 32 and the stack is mounted on a shaft 40 between an end disc 10 having only projections 16, which is force fitted to the shaft 40 by a chord portion engaging a flat 41, and a disc 20 having only holes to receive projections 36. A resilient washer 53 holds the stack together and applies axial pressure which engages the projections in the holes to ensure correct positioning of the cam discs. The assembly is driven at a constant speed by a motor 54 through gearing 55 engaging a gearwheel portion 14 of the disc 10. In some cases alternate intermediate discs may have projections or recesses on both faces.
