Abstract
A mechanism for selectively rotating pocket assemblies between first and second limit positions. The mechanism comprises a cam follower block mounted on the shaft of the pocket assembly for limited movement relative to the shaft in a predetermined plane and direction. Biasing means normally urges said cam block toward the first limit position. Upper and lower cam followers have centers of rotation to one side of and parallel to said predetermined plane. A profile cam is mounted on the shaft and rotatable relative to the cam block having two diametrically opposed shoulders and arcuate profile surfaces connecting the shoulders. The spring biasing means normally biases the cam block and the profile cam to a position where one of the cam followers engages a shoulder to prevent rotation of the cam block and therefore the pocket assembly and wherein the other cam follower is spaced from the profile cam. The other cam follower is engagable with a profile cam track comparable to displace the cam follower block upwardly to disengage the first cam follower and effect rotation of the profiled cam and pocket assembly.
