Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
336 words
A tool for applying a strap having a lock portion and end portion to a bundle of wires or similar object, said tool comprising: a tool body having a generally pistol-like configuration with a nose portion, a rear portion, and a handle portion; an opening in said body nose portion communicating with an interior passageway in said body for receiving the end portion of a strap; a gripping mechanism reciprocable along said body for engaging said strap end portion and pulling said end towards said body rear portion to thereby place said strap end portion under tension; an operating lever mounted on said body for movement relative thereto and having a normal working stroke between first and second positions; a tension release mechanism for operatively connecting said operating lever to said gripping mechanism when the tension in said strap end portion is below a predetermined value, and for operatively disconnecting said operating lever from said gripping mechanism when the tension in said strap end portion reaches said predetermined value; a cutoff member mounted on said body for movement relative thereto and having a blade means disposed adjacent said opening in said body nose portion, said cutoff member being inoperative during the normal working stroke of said operating lever; selector means located on said body and movable between first and second settings; means for limiting the movement of said operating lever to its normal working stroke when said selector means is at said first setting; and means for permitting movement of said operating lever beyond its normal working stroke to a third position when said selector means is at said second setting, said operating lever having means for actuating said cutoff member when moved to said third position; whereby said tool is operative to apply a strap to a predetermined tension when said selector means is at said first setting, and is operative to apply a strap to a predetermined tension and to sever the strap end portion when said selector means is at said second setting.

Claim 3
Dependent Claim
65 words
A tool for applying a strap as set forth in claim 1 wherein said gripping mechanism has an elongated slot formed therein, a depression formed in said slot, and wherein said tension release mechanism comprises roller means normally positioned within said depression, said roller means being movable out of said depression and into said slot upon the tension in said strap reaching said predetermined value.
Claim 4
Dependent Claim
50 words
A tool for applying a strap as set forth in claim 2 wherein said tension release mechanism further comprises shoulder means positioned for engaging stop means located on said tool body for limiting movement of said tension release mechanism when the tension in said strap is below said predetermined value.
Claim 5
Dependent Claim
63 words
A tool for applying a strap as set forth in claim 1 wherein said cutoff member has roller means mounted thereon and wherein said operating lever includes cam means for engaging said roller means when the operating lever is moved from its second position to its third position to thereby move said cutoff member and said blade means to effect a severing operation.
Claim 6
Dependent Claim
40 words
A tool for applying a strap as set forth in claim 4 wherein said operating lever includes a pair of joined slots and wherein said selector means includes a member disposed for movement within one of said pair of slots.
Claim 7
Dependent Claim
61 words
A tool for applying a strap as set forth in claim 5 wherein one slot of said pair of slots is shorter than the second slot of said pair, said one slot being operative to limit movement of said operating lever to its normal working stroke whereas said second slot permits movement of said operating lever to its said third position.
Claim 8
Dependent Claim
29 words
A tool for applying a strap as set forth in claim 4 further comprising anvil means disposed opposite said blade means for cooperation therewith to effect the severing operation.
