(under subclass 375) Device wherein proper timing of the tool stroke with respect to the clamp actuation is assured by provision of means responsive to a predetermined travel of a clamp jaw or to predetermined developed clamping force, which means generates a signal or impulse which causes or permits initiation of a tool stroke.
(1) Note. The sequencing means, as defined in this subclass, is a specific application of an "interlock" (for which in general see subclasses 399+).
(2) Note. Mere timed actuation of clamp and tool in sequence, as by properly phased cranks or cams, does not meet the definition of "sequencing means".
