Appeal No. 1994-4016
Application No. 07/793,824
as follows (page 9, lines 13-17 and 19-26, and page 10, line
1):
The tracer subassembly 150, having upright member
185 and horizontal member 190, is supported by
sidewalls 165 and 170, which are fastened at right
angles to assembly support 175. The assembly
support 175 is attached perpendicularly to plate 55.
. . . .
In the preferred embodiment shown in Figure 7,
the tracer subassembly 150 is a two piece apparatus
consisting of an upright member 185 and a horizontal
member 190, so that when fitted together, the pieces
have a predominately L-shaped configuration. The
surfaces on the outside of the L, 195 and 200 are
rounded, while the inside surface 205 of the upper
member 185 is beveled at an angle pointing towards
the top of the L. The upright member 185 and
horizontal member 190 have excess material removed
from them to form a cavity 210 so as to accommodate
a roller 155.
We observe that the specification defines “a means for
adjusting the tracing means” as follows (page 10, lines 11-
21):
The tracer subassembly 150 is secured into
position with tracing adjustment assembly 160. The
tracing adjustment assembly 160 consists of two
extensible rods 230 and 235 extending through
threaded bores in assembly support 175. The rods
have threads 240 and 245 so that when rods 230 and
235 are turned, the distance between the end of the
rods 260 and 265 and the assembly support 175 can be
varied. The end 265 of rod 235 is positioned so
that it makes contact with the beveled portion 205
