DEFINITION

Classification: 83/746

(under the class definition) Device having a cutting tool comprising a member of substantial length having a work cutting edge extending along its length, said member being adapted to move such that each point along the elongated cutting edge has a component of motion to-and-fro and generally parallel to said work cutting edge, and including a means for supporting a means for supporting or guiding said cutter to move to and fro.

(1) Note. In the definitions of the subclasses indented hereunder, the phrase "cutting span" will be used to designate that portion of the moving cutting edge which is transiently in engagement with the work.

(2) Note. A device having means to guide a reciprocable-along-elongated-edge type tool while it moves toward and/or through the work (i.e., infeed) and which relates to a reciprocable type tool, is placed in subclasses 746+ rather than subclasses 821+, since these devices function to guide the tool during its basic movement (i.e., to-and-fro reciprocations) and in addition, function to determine the direction of tool infeed movement and/or provide support for the tool.
