Appeal No. 2003-1472
Application No. 09/606,955
a track (or, means) for selectively changing the first
path of travel of the end to another path of travel, said
another path of travel having a second cutting stroke and
a second return stroke,
wherein the first path of travel is characterized by
movement at least partially in the first cutting
direction during the first cutting stroke, and wherein
said another path of travel is characterized by movement
at least partially in the second (opposite) cutting
direction during the second cutting stroke.
Thus, each of the independent claims on appeal in one way or
another calls for a spindle that is capable of moving along a first
path of travel and another path of travel, wherein the first path
of travel is characterized by movement of the spindle end at least
partially in a first cutting direction during a first cutting
stroke, and wherein the said another path of travel is
characterized by movement of the spindle end at least partially in
a second opposite cutting direction during a second cutting stroke.
Enders, the examiner’s primary reference in each of the
rejections under 35 U.S.C. § 103(a), is directed to a jig saw
wherein the spindle has an adjustable path of travel. More
particularly, Enders discloses a spindle 28 mounted in a pivoting
bearing 30 for allowing both sliding and pivoting motion of the
spindle relative to the tool housing. Crank pin 25, 26 engages a
transverse slot in yoke member 27 carried by the spindle so that
when the crank in rotated, a reciprocating motion is imparted to
