the spindle. The Enders jig saw further includes an adjustable
guide channel 35, 35a which receives the yoke member for guiding
the movement thereof. As can be seen from Figures 5A-5D, by
changing the angle of inclination of the guide channel, the path of
travel of the spindle can be adjusted. More particularly, Fig 5A
illustrates a first position of the guide channel that causes the
saw blade 31 to move along a first path of travel wherein the saw
blade reciprocates with no movement in the cutting direction during
the cutting and return strokes, whereas Figs 5B-5D illustrate
gradually increasing angles of inclination of the guide channel
wherein the saw blade reciprocates in second, third and fourth
paths of travel, each characterized by movement of the saw blade
toward the workpiece W during the cutting (ascending) stroke and
away from the workpiece during the return (descending) stroke.
Ketchpel, the examiner’s secondary reference in each of the
rejections under 35 U.S.C. § 103(a), is directed to a reciprocating
saw. An aim of Ketchpel is to provide a new and improved saw blade
holder (generally, element 120) “for selectively holding a saw
blade in a vertical position with the saw blade teeth at either the
upper or lower edge of the saw blade or in a horizontal position
with the saw blade teeth at either the right side or left side of
the saw blade” (column 1, lines 17-21). Figure 4 shows the saw
