Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 188 words
A high-speed feedstock cutting and forwarding device for use with a bolt nut forming machine comprising: a cutter for cutting feedstock, said cutter having an aperture in the configuration of the external shape of the product to be formed for receiving and holding the feedstock; means for driving said cutter in a reciprocal manner; means for returning said cutter and resultant cut nut blank to the normal position of said cutter after the feedstock has been cut; a transferring and conveying disc structurally adapted and provided at a suitable position in relationship to said cutter for receiving nut blanks cut thereby and for conveying cut nut blanks away from the cutter; and driving means operatively connected to said disc to drive said disc in a rotary motion, said device being characterized in that the cutter is driven through a moving distance by said cutter driving means only about one half of the distance through the feedstock to achieve cutting thereof, and said return means returns said cutter and resultant nut blank the same distance to a suitable position for introduction of the resultant nut blank to said disc.
Claim 2
Dependent Claim 188 words
A high-speed feedstock cutting and forwarding device for use with a bolt nut forming machine comprising: a cutter for cutting feedstock, said cutter having an aperture in the configuration of the external shape of the product to be formed for receiving and holding the feedstock; means for driving said cutter in a reciprocal manner; means for returning said cutter and resultant cut nut blank to the normal position of said cutter after the feedstock has been cut; a transferring and conveying disc structurally adapted and provided at a suitable position in relationship to said cutter for receiving nut blanks cut thereby and for conveying cut nut blanks away from the cutter; and driving means operatively connected to said disc to drive said disc in a rotary motion, said device being characterized in that the cutter is driven through a moving distance by said cutter driving means only about one half of the distance through the feedstock to achieve cutting thereof, and said return means returns said cutter and resultant nut blank the same distance to a suitable position for introduction of the resultant nut blank to said disc.
Claim 3
Dependent Claim 29 words
A device as set forth in claim 1 wherein said cutter comprises a blade and said aperture is disposed on said blade adjacent to one edge of said blade.
Claim 4
Dependent Claim 56 words
A device as set forth in claim 2 wherein said means for driving said cutter includes a shaft supporting said blade on one end thereof, a roller operatively connected to the other end of said shaft, and a driven cam cooperating with the roller for driving said shaft in a reciprocal manner through a suitable distance.
Claim 5
Dependent Claim 19 words
A device as set forth in claim 3 wherein said return means comprises a spring disposed about said shaft.
