Abstract
Abstract A device for transmitting accurate movements from a rotary input shaft to two separate axis-movable members comprises a first member which is guided for movement along one axis and a second member which is guided on the first member for movement along a second axis. The shaft carries a separate cam for driving each member which is adjustably connected to at least one of the members so that the controlled movement may be adjusted for each shaft rotation. The adjustable connection advantageously includes a lever with a roller follower which is guided by the cam and an arm which carries a shiftable pivot connection to a slideway carried on one of the movable members.
