12, with which it is adapted to directly coact with the cutting edge of a blade 10
positioned at the inner portion of the working face of a movable jaw 12. The blade 10 is
oppositely beveled to provide an elongate cutting edge 14, which has cutting coaction
with the face 9 of the anvil 7. The face 9 extends on a line oblique to the jaw face 6
while the edge 14 is substantially parallel to the jaw face 11 of jaw 12.
In the embodiment of Petersen's invention illustrated in Figure 3, the blade 24
carried by the jaw 25 is substantially the same as the jaw 12 as embodied in Figures 1
and 2. Coacting with the blade 24 is a cutter member 26 which is also disposed beyond
the working face of the jaw in the same manner as the anvil 7 in Figures 1 and 2. The
cutting edge b of member 26 is in direct alignment with the cutting edge c of the blade
24. In the embodiment of Petersen's invention illustrated in Figure 4, the cutting blade
or member 27 carried by the jaw 28 is reduced by cutting away as at 29, a portion of the
side face of the jaw 28 inwardly so that the same may have close contact with the
cutting blade or member 30 carried by the stationary jaw 31 of the wrench.
After the scope and content of the prior art are determined, the differences
between the prior art and the claims at issue are to be ascertained. Graham v. John
Deere Co., 383 U.S. 1, 17-18, 148 USPQ 459, 467 (1966).
