Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
A high-speed feedstock cutting and forwarding device for use with and adaptable to a bolt nut forming machine, said device comprising a cutter for cutting feedstock, said cutter including means for driving said cutter in a reciprocal manner; and a transferring and conveying disc for conveying cut nut blanks away from the cutter, said disc operatively connected to and driven in a rotary motion by suitable driving means and being structurally adapted and provided at a suitable position in relationship to said cutter for receiving nut blanks cut thereby, 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 means to return the resultant blank the same distance to a suitable position for introduction to the said disc.
Claim 2
Dependent Claim
142 words
A high-speed feedstock cutting and forwarding device for use with and adaptable to a bolt nut forming machine, said device comprising a cutter for cutting feedstock, said cutter including means for driving said cutter in a reciprocal manner; and a transferring and conveying disc for conveying cut nut blanks away from the cutter, said disc operatively connected to and driven in a rotary motion by suitable driving means and being structurally adapted and provided at a suitable position in relationship to said cutter for receiving nut blanks cut thereby, 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 means to return the resultant blank the same distance to a suitable position for introduction to the said disc.
Claim 3
Dependent Claim
225 words
A device as set forth in claim 1 wherein the cutter consists of a blade having an indentation in the shape of one half of the external shape of the product to be formed, said blade being mounted on one end of a shaft, the other end of which is operatively connected to a roller which in turn is mounted on at least one bearing; a cam cooperating with the roller for the purpose of driving the shaft in a reciprocal motion through a suitable distance; a pressure contact spring for holding the blank in a suitable position; said transferring and conveying disc comprising a rotary disc with suitable indentations along its periphery for holding cutoff blanks and coacting with suitable driving means to drive said disc in a rotary motion for the purpose of transferring and conveying said blanks in a like motion, said rotary disc being provided at a suitable position in relationship to the cutter for receiving cutoff nut blanks cut off thereby; said device characterized in that after a blank has been cut off, the blank will be drawn back to its original position where the blank will be pushed from the blade of the cutter into a properly aligned indentation of the rotary disc by virtue of the forward advancement of the feed material used to produce the nut blanks.
