DEFINITION

Classification: 83/223

(under subclass 202) Device in which a mechanism, driven by movement of either the tool or the work-feed means, is caused to accumulate potential energy which is later released to actuate the other of the two means.

(1) Note. This arrangement is found in many small hand-actuated machines, wherein, for example, a tool-retracting spring is stressed during the tool cutting stroke and part of its stored energy is utilized, during the

return of the tool, to advance the work into position for the next cut.

229, for work-feed means driven by tool or tool support on return movement of tool.

582+, for a constantly urged tool, especially subclasses 588+ for return-stroke-biased tools.
