International ClassesB27B 019/09B23D 049/16 B23D 051/16 AbstractA method of reciprocating a spindle of a reciprocating saw, including the steps of reciprocating the front end of the spindle along a first path during the cutting stroke and along the same first path during the return stroke, and adjusting the saw such that the front end reciprocates along a second path during the cutting stroke and along the same second path during the return stroke, the second path being oblique to the first path. The present invention also provides a method of reciprocating a spindle of a reciprocating saw, including the steps of moving the front end along a first cutting path during the cutting stroke, the first cutting path characterized by movement at least partially in a first cutting direction, returning the front end along a return stroke (e.g., along the first cutting path), and adjusting the saw such that the front end moves along a second cutting path during the cutting stroke, the second cutting path characterized by movement at least partially in a second cutting direction.Field of SearchPROCESSESWith reorientation of tool between cuts With means to reciprocate saw In uniplanar compound path Including connecting rod articulated with saw blade or support Affixed to work SPOONS Hammer head reciprocates along fixed transverse axis Arcuate or rotary movement selectively releasable or variable independent of reciprocation Hammer head moves in arcuate path or rotates Arcuate or rotary movement transmitted to tool With means to reciprocate tool DRIVE BY MEANS REACTING TO ROTATING ECCENTRIC MASS | |
