DEFINITION

Classification: 83/241

(under subclass 240) Means to vary the length or amount of work fed toward the tool at each one of the series of stops and starts of the work which characterize the operation of a device of the type of subclass 202, without necessitating the replacement of any machine part to bring about such variation.

(1) Note. This subclass includes adjustment of work-feed by varying the effective length of a link or shape of a cam, where such link or cam is not part of the actual drive to the work-feed means, but is only a control element.

SEE OR SEARCH THIS CLASS, SUBCLASS:

69, for machine which stops after cutting a predetermined number of products.

203+, for unicyclic machine.

208, for work-length-determining means driven by the work (e.g., measuring wheel). 233, for devices which inherently permit the selection of a length of stock to be cut (within a limit) by feeding the amount desired and then reversing the feed lever to cause cutting to occur.

234, for means to vary the number of work-feed increments between tool strokes.

268, for feed limited by work stop.

399+, for a work-feed actuator or controller which can be manipulated in a direction to lock the work-feed means and permit or cause actuation of a tool.
