Description: |
| This patent is an improvement on patent #9,250X.
Abstract:
In my improved machine the rod or bar is passed directly in between the gripping-dies, and is cut off by a cutter on a level with and at the outer end of said dies. It was found impracticable, also, in the machine us originally constructed to draw out and distribute the metal by the action of the segment-dies used in that machine so as effectually to fill the space between the gripping-pieces, and thereby to give the metal the proportionate thickness and width requisite in its different parts. In my improved machine this difficulty is obviated by giving to the swages a somewhat greater extent of motion than is given in the same time to the sliding frame, by which means they exert a rubbing or drawing power on the metal, drawing it from the cutting end toward the rear, and thereby fill the space between the gripping-dies. In my original plan the machine by which the iron was grooved and punched was distinct from that by which the rolling and drawing were effected. In my improved machine both of these operations are performed in succession on the same machine, thereby greatly diminishing the time required for their performance; preventing the loss of heat, and insuring greater accuracy in the work.
Claim:
The manner of combining and arranging the cutters and gripping dies in the said machine so that the former be in the same plane with the latter, thereby allowing the bar of iron to be passed directly in between them. |
