DEFINITION

Classification: 24/640

Including slidably connected and guided element on receiving member:

(under subclass 633) Operator* including an element connected to a remaining stationary component of the receiving member by two distinct, rigid* formations which (1) are each integral with or fixedly attached to the element and the component, and (2) have mutually cooperating surfaces both (a) sliding relative to each other and (b) restricting the relative motion of the element to substantively a single primary direction.
