Abstract

An improved linesman pliers preferably includes a lower handle, a lower jaw, a pair of link plates and a combination upper handle and jaw. The lower handle includes a lower handle portion and a lower pivot portion. The lower jaw preferably includes a lower jaw portion, a pivot boss, a stripper projection and a crimp projection. At least one upper stripper cavity is formed in the stripper projection, which is aligned with the at least one lower stripper cavity formed in the lower pivot portion. The pivot boss is pivotally engaged with the lower pivot portion. A pair of link plates pivotal engage the combination upper handle and jaw with the lower handle. The combination upper handle and jaw includes the upper handle portion and an upper jaw. The upper handle portion is pivotally engaged with the lower jaw portion.

Claims

1. An improved linesman pliers comprising:

a lower handle includes a first end, at least one lower stripper cavity is formed in said first end;

a lower jaw is pivotally engaged with said first end of said lower handle at a first pivot point, a stripper projection extends from said lower jaw adjacent said first pivot point, at least one upper stripper cavity is formed in said stripper projection, wherein said at least one lower stripper cavity is aligned with said at least one upper stripper cavity;

an upper handle includes an upper handle portion and an upper jaw, said upper jaw extends from a first end of said upper handle portion, said lower jaw is pivotally engaged with said upper jaw at a second pivot point; and

at least one link plate having one end pivotally engaged with said first end of said lower handle at a third pivot point and an opposing end pivotally engaged with said first end of said upper handle portion at a fourth pivot point;

wherein the lower stripper cavity is located on the lower handle substantially between the first and third pivot points.

2. The improved linesman pliers of claim 1 wherein:

a crimp cavity is formed in a top of said upper handle portion, adjacent said upper jaw; and

a crimp projection extends from said lower jaw, said crimp projection includes a crimp extension, said crimp extension extends from a side of said crimp projection, said crimp extension is sized to be received by said crimp cavity, when said improved linesman pliers is closed.

3. The improved linesman pliers of claim 1 wherein:

a jaw relief slot is formed between said upper jaw and said upper handle portion, said jaw relief slot is sized to receive a portion of said lower jaw.

4. An improved linesman pliers comprising:

a lower handle having a lower handle portion and a lower pivot portion;

a lower jaw pivotally engaged with said lower handle at a first pivot point passing through the lower pivot portion, said lower jaw includes a crimp projection extending upward from said lower jaw away from said first pivot point, said crimp projection includes a substantially cylindrical crimp extension extending laterally therefrom, said crimp extension having a central cylindrical axis which is substantially parallel to the axis of said first pivot point;

an upper handle includes an upper handle portion and an upper jaw, said upper jaw extends from a first end of said upper handle portion, a second pivot point pivotally engaging said lower jaw with said upper jaw, a crimp cavity is formed between said upper handle and said upper jaw opposite said lower jaw and said lower handle, said crimp cavity is sized to receive said crimp extension; and

at least one link plate having one end pivotally engaged with said lower pivot portion at a third pivot point and an opposing end pivotally engaged with said first end of said upper handle.

5. The improved linesman pliers of claim 4 wherein:

at least one lower wire stripper cavity is formed in an edge of said lower pivot portion; and

said lower jaw includes a stripper projection, at least one upper wire stripper cavity is formed in said stripper projection.

6. The improved linesman pliers of claim 4 wherein:

a jaw relief slot is formed between said upper jaw and said upper handle portion said jaw relief slot is sized to receive a portion of said lower jaw.

7. An improved linesman pliers comprising:

a lower handle includes a first end, at least one lower stripper cavity is formed in said first end;

a lower jaw is pivotally engaged with said first end of said lower handle at a first pivot point, a lower cutting edge is formed on said lower jaw, a stripper projection extends from said lower jaw adjacent said first pivot point, at least one upper stripper cavity is formed in said stripper projection, wherein said at least one lower stripper cavity is aligned with said at least one upper stripper cavity;

an upper handle includes an upper handle portion and an upper jaw, said upper jaw extends from a first end of said upper handle portion, said lower jaw is pivotally engaged with said upper jaw at a second pivot point, an upper cutting edge is formed on said upper jaw; and

at least one link plate having one end pivotally engaged with said first end of said lower handle at a third pivot point and an opposing end pivotally engaged with said first end of said upper handle portion at a fourth pivot point;

wherein the lower stripper cavity is located on the lower handle substantially between the first and third pivot points.

8. The improved linesman pliers of claim 7 wherein:

a crimp cavity is formed in a top of said upper handle portion, adjacent said upper jaw; and

a crimp projection extends from said lower jaw, said crimp projection includes a crimp extension, said crimp extension extends from a side of said crimp projection, said crimp extension is sized to be received by said crimp cavity when said improved linesman pliers is closed.

9. The improved linesman pliers of claim 7 wherein:

a jaw relief slot is formed between an upper jaw and said upper handle portion, said jaw relief slot is sized to receive a portion of said lower jaw.
