DEFINITION

Classification: 92/13.7

(under subclass 13) Apparatus in which there is provided means for transmitting motion to or from the working member comprising at least one element (e.g., cam, gear, link, etc.), which is mechanically associated with and movable relative to the working member; the selectively positionable or movable means for changing the extent of working member movement being operatively associated with said relatively movable transmission element to either (1) limit the motion of said element for changing the extent or varying the end limits of working member or (2) change the driving relationship of said element relative to the working member or another element of the transmission for the purpose of changing the extent or varying the end limits of working member movement.
