UNITED STATES PATENT OFFICE.
LOUIS PRAHAR, OF NEW YORK, N. Y.
IMPROVEMENT IN FEED DEVICES FOR PUNCHlNG-MACHINES.
Specification forming part of Letters Patent No. 180,924, dated August 8, 1876; application filed July 11, 1876.
material forward to the cutting-tool as it is,
required, and which shall be simple in construction. convenient in use, and readily applied to the press.
The invention will first be described in connection with the drawing, and then pointed out in the claim.
Similar letters of reference indicate corresponding parts.
Aare the legs. B is the bed-plate. O is the pedestal. D is the pendulum. E is the toolholder. F is the tool-holder guide. G is the tool, and H is the die, about the construction of all of which parts there is nothing new. 1
- is the pivot, which is attached to the pendulum D, and works in bearings in the pedestal C. To the pivot I is attached an arm, J, to the outer end of which is pivoted a connecting-rod, K, the lower end of which is pivoted to a small crank, L. The crank L is pivoted to the journal of the upper feed-roller M, and
to said crank is pivoted a pawl, N, which is held down by a spring, 0, and engages with the teeth of a gear-wheel, P, attached to the upper feed-roller M. The teeth of the gearwheel P mesh into the teeth of a gear-wheel, Q, attached to the lower end of the feed-roller M, so that the said rollers M may move together, and in opposite directions, to carry forward the material to be operated upon. The feed-rollers M are pivoted to a small frame attached to the bed-plate B.
With this construction the movement of the pendulum D will operate the feed-rollers M, to carry the material forward to the cutting-tool G, the rapidity of the feed being regulated by the size of the gear-wheels P Q.
The arm J may be connected with the pivot of the pendulum, as herein shown and described, with the pendulum itself, or with the tool-holder, as may be most convenient.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of pivot I, having pendulum D and arm J, with the pivoted rod K, the crank L, having spring-pawl N, and the gearwheels P, as shown and described, to form an improved mechanism for operating the feedrolls of a punching-machine.
