Abstract
A shearing apparatus comprising an index portion, a thumb portion, and a ripping portion. The index portion has an index blade arcuately movable in a first direction defining an arc about a pivot. The thumb portion is pivotably connected to the index portion at the pivot, and has a thumb blade arcuately movable in a second direction that is substantially opposite the arc of the first direction. The ripping portion is disposed on the thumb blade or the index blade, and has a ripping blade manually movable in a third direction at an angle, parallel or perpendicular to a line parallel to at least one of the index blade and the thumb blade.
Claims14
A shearing apparatus comprising:
- an index portion (12) having a finger hole and an index blade (12′) accurately movable in a first direction (A) defining an arc about a pivot (14), wherein the finger hole and the index blade are disposed on opposite sides of the pivot;
- a thumb portion (16) pivotably connected to the index portion (12) at the pivot (14), the thumb portion (16) having a thumb hole and a thumb blade (16′) accurately movable in a second direction (B), wherein the second direction is substantially opposite the arc of the first direction, and wherein the thumb hole and the thumb blade are disposed on opposite sides of the pivot;
- and
- a ripping portion (18) disposed on and movable with one of the thumb blade (16′) or the index blade (12′), wherein the ripping portion (18) is a separate component that is secured to the thumb blade (16′) or the index blade (12′), further wherein the ripping portion (18) includes a main portion (19) secured to the index blade (12′) or the thumb blade (16′), and a leg (21) that extends away from the main portion (19), further wherein the main portion (19) of the ripping portion (18) is provided with a channel (42) for placement over a lower edge of the thumb blade (16′) or the index blade (12′), further wherein the ripping portion (18) has a ripping blade (20) manually movable in a third direction (C) at an angle, parallel or perpendicular to a line (L) parallel to at least one of the index blade (12′) and the thumb blade (16′), further wherein the ripping blade (20) is disposed between the main portion (19) and the leg (21), further wherein the index blade or the thumb blade includes a tab portion (17) being inserted in a recess (66) of the ripping portion (18), the tab (17) extends substantially perpendicular to the first direction (A), the second direction (B) and the third direction (C) of the index portion (12), the thumb portion (16) and the ripping blade (20) respectively, and wherein the ripping portion (18) is disposed at an end of the index blade (12′) or the thumb blade (16′) that is remote from the finger hole or the thumb hole on a side of the pivot opposite the finger hold or the thumb hole.
