Application No. 09/368,781
36. The tool according to claim 35, wherein said second lever arm includes a
cutting end having a flat surface that is generally perpendicular to said insert,
and wherein said flat surface is configured such that, when said first and second
lever arms come together, said insert comes into contact with said flat surface to
sever a material.
The teachings of Root have been set forth above in our discussion of claim 37.
Petersen's invention relates to a wrench of a toggle type provided with wire
cutting means making it possible to cut very heavy wire ordinarily impossible to sever by
a squeezing action. An object of Petersen's invention was to provide a tool including
relatively movable jaws one of which carries an anvil and the other having a cutting
edge opposed to the anvil wherein the anvil is provided with a flat working surface
whereby the necessity of keeping the anvil and cutting edge in perfect sidewise
alignment in order to effect the cutting of a wire is eliminated.
In the embodiment Petersen's invention illustrated in Figures 1 and 2, A denotes
an elongated handle member. The outer end portion of the handle A is provided with a
stationary jaw 5 with a serrated working jaw face 6. Partially extending within the
handle A and partially overlying the inner or adjacent end portion of the working face 6
is an anvil 7. The body of the anvil 7 projects a predetermined distance beyond the
working face 6 and has a longitudinally flat working face 9 directed toward the other jaw
