[Also in Division D1] A tapered cam comprising a concentric surface 11 and three arcuate surfaces 12, 13 and 14 is rotatably mounted on a spindle 9 and is driven by bevel gears 3, 4 from a shaft 2. Manual rotation of a graduated cover 22 allows a plunger 33, which is spring-urged upwardly against the inclined face 38 of an annulus projecting from under the cover, to move the follower axially of the cam to change the follower movement derived from the cam. |
