| Abstract:
I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings.
Claim:
The general combination and arrangement of the respective parts of the before described machine, in which the blanks to be nicked are held in a blank wheel, operated upon by friction rollers; and made to revolve through the intermedium of endless screws, and toothed wheels substantially in the manner described, while the nicking is effected by means of a revolving cutter. I do not intend to claim either of the individual parts in its separate character, but only as above described, the combined operation of these parts so as to produce the intended effects. |
