cavity 140.
. . . .
An alternative embodiment as shown in Figure
16, where the invention is substantially the same as
the preferred embodiment, except that the tracing
assembly consists of a cube 345 attached to assembly
support 300, in turn connected to the plate 55, as
shown in Figure 1. Disposed on either side of the
cube 345 are movable links 350 and 355. Attached to
the movable links 350 and 355 are rollers 360 and
365. Rods 310 and 320 having threads 330 and 335
extend through the assembly support 300 so that when
the distance between the links 350 and 355 and the
assembly support 300 is increased or decreased by
turning rods 310 and 320, the rollers 360 and 365
are raised or lowered, adjusting the cutting depth
of the cutter 305. Locknuts 340 lock rods 310 and
320 in place.
. . . .
In another alternate embodiment as shown in
Figure 19, the invention is substantially the same
as that shown in the preferred embodiment, except
that the upright and horizontal members of the
tracing assembly are replaced with upright cam 595
and horizontal cam 590. The cams 595 and 590, like
the upright and horizontal members of the preferred
embodiment are adjustable via adjusting rods 510 and
515.
We observe that the specification defines "a sliding support
means" as follows (page 7, lines 20-25):
The [sliding] support consists of parallel bars 65
and 70 (not shown) (See also Figure 15) oriented at
an angle. It may be desired, but not limited
thereto, to use a 45 degree angle to the plane
