DEFINITION

Classification: 83/297

(under subclass 296) Device in which the means to vary the frequency of the tool-action-starting mechanism includes at least two means, one of said means comprising an element which, when activated, effects the initiation of the tool action, the other of said means comprising a plurality of pin members moving in a closed path, one or more of which pin members along the closed path may be selectively positioned so as to describe a second closed path (parallel to the first

named path) which intersects the location of such element at the selected position(s) along the first named path, whereby the positioned pin member(s) will intermittently or periodically engage and move, or otherwise activate, the element in the desired frequency of occurrences.

(1) Note. The positionable pins may be mounted on a wheel or endless chain for movement in the first named closed path, and any selected pin may be shifted into the second closed path either manually or by mechanical means.
