Abstract
824,083. Cam mechanism. BRITISH THOMSON-HOUSTON CO. Ltd. April 24, 1957 [April 24, 1956], No. 12532/56. Class 80 (3). A rotatable cam 7 actuating a follower 7<SP>1</SP> has in different transverse planes different contours such as 11, 12 which are automatically successively rendered effective by axial movement of the rotating cam shaft 1. The contour may change abruptly or progressively between successive planes, and the cam may comprise a single or a composite member. As shown the shaft 1 carries three cams 7, 8, 9 each having two different contours and a cam 10 having a conical surface. A spring-loaded detent 5 engages an internally threaded portion 4 of the shaft 1 so that as the shaft rotates it moves telescopically into its driving shaft 2 against the restoring force of a spring 3 and changes the effective contours of the cams. At the end of a cycle, or at any other desired time, the detent 5 is disengaged so that the shaft 1 returns to its original position under the action of the spring 3. Stops 6 limit the shaft movement. It is stated that the restoring force may be provided by a suspended weight instead of the spring 3. The cam mechanism is applicable to the control of a valve in the effluent-neutralizing apparatus described in Specification 824,081, [Group XXXVI].
