Abstract
Abstract A combination tool comprises first and second handles movably pivoted together at a pivot axis, with respective first and second shanks extending from the pivot axis and joined to the corresponding handle. A tool member is joined substantially normal to each shank, and substantially parallel with the pivot axis, each tool member having a flat end surface substantially parallel with the corresponding shank. The upper surface of the tool members have opposing indentations therein, serving as a recess for receiving wire for stripping purposes. When the opposing surfaces of the tool members abut one another, the end surfaces of the tool member define a flat hammer face.

Claim 1
Independent Claim
221 words
A combination tool comprising: a first handle; a second handle movably joined with said first handle at a pivot axis; a first shank extending from said pivot axis and joined with said first handle; a second shank extending from said pivot axis and joined with said second handle; a first tool member joined and substantially normal to said first shank, and substantially parallel with said pviot axis, said tool member having a first flat end surface substantially parallel with said first shank; a second tool member joined and substantially normal to said second shank, and substantially parallel with said pivot axis, said tool member having a second flat end surface substantially parallel with said second shank; said first and second tool members having opposing surfaces with corresponding openings therein substantially parallel with said shanks and substantially normal to said pivot axis, one of said openings comprising an oblong opening; a protrusion extending from one of said tool members into said oblong opening; means for changing the dimension of said protrusion into said oblong opening; and wherein said first and second end surfaces define a flat hammer face with said opposing surfaces of said tool members abutting each other, and said openings define means for stripping insulation from wire extending between said tool members in a direction substantially parallel with said shanks.
Claim 2
Dependent Claim
221 words
A combination tool comprising: a first handle; a second handle movably joined with said first handle at a pivot axis; a first shank extending from said pivot axis and joined with said first handle; a second shank extending from said pivot axis and joined with said second handle; a first tool member joined and substantially normal to said first shank, and substantially parallel with said pviot axis, said tool member having a first flat end surface substantially parallel with said first shank; a second tool member joined and substantially normal to said second shank, and substantially parallel with said pivot axis, said tool member having a second flat end surface substantially parallel with said second shank; said first and second tool members having opposing surfaces with corresponding openings therein substantially parallel with said shanks and substantially normal to said pivot axis, one of said openings comprising an oblong opening; a protrusion extending from one of said tool members into said oblong opening; means for changing the dimension of said protrusion into said oblong opening; and wherein said first and second end surfaces define a flat hammer face with said opposing surfaces of said tool members abutting each other, and said openings define means for stripping insulation from wire extending between said tool members in a direction substantially parallel with said shanks.
Claim 3
Dependent Claim
62 words
The tool recited in claim 1 wherein said dimension changing means comprises: one of said first and second tool members having a threaded hole extending threin substantially transverse to said oblong opening, with said protrusion extending through said threaded hole and into said oblong opening; means for retaining said protrusion in said threaded hole; and a screw fitted into said threaded hole.
Claim 4
Dependent Claim
41 words
The tool recited in claim 1 wherein: each said tool member further includes a tapered portion extending away from the corresponding one of said shanks; and wherein said tapered portions define a pointed extension adapted to pull staples and the like.
Claim 5
Dependent Claim
17 words
The tool recited in claim 3 wherein said tapered portions are substantially parallel with said pivot axis.
Claim 6
Dependent Claim
52 words
The tool recited in claim 3 further comprising: each shank defining a cutting blade opposing a line cutting blade on the other one of said shanks; and wherein said cutting blades define means for cutting wire or the like inserted between said shanks in a direction substantially parallel with said pivot axis.
