JAMES WHITELAYV, OF ST. LOUIS, MISSOURI.

PERFORATOR.

SPECIFICATION forming part of Letters Patent No. 380,614, dated April 3, 1888.

Application filed May 31, 1887. Serial No. 239.770. (No model.)

To all whom it may concern.-

Be it known that I, JAMES WHITELAW, of St. Louis, Missouri, have made a new and useful Improvement in Perforators, of which the followingis a full, clear, and exact description.

A series of punches, in number corresponding to the letters, numbers, or characters to be cutout, is held, and the punches are adapted to be operated vertically in an overhanging guide at the front of the machine, and in the base-plate, beneath the punches, is a corresponding series of dies. In the upper part of the machine, in the rear of and parallel with the guide, is abar upon which is journaled the lever used to depress the punches. The lever can also he slipped upon the bar to bring it, as desired, over or in line with any one of the punches. In addition to the lever a frame is hung and adapted to he slipped upon the bar, and it is preferably connected with the lever, to be moved wit-h it as the lever is slipped upon the bar. The frame carries the paper-holder as well as an escapement mechanism for feeding the paper-holder as the paper is perforated, and the lever, in addition to operating the punches, is constructed to operate the escapement mechanism, by which means, after the paper has been inserted in the holder, the operator can manipulate the entire machine and complete the perforating by means of the lever only.

In the annexed drawings, making part of this specification, the most desirable mode of carrying out the improvement is exhibited.

Figure 1 is a plan of the machine. Fig. 2is a vertical cross-section on the line 2 2 of Fig. 1. Fig. 3 is a view in perspective from the rear of the sliding mechanism. Fig. 4 is a detail, being a view in perspective from the rear of the punch and escapement-operating lever. Fig. 5 is a view in perspective from the front of the machine, and Fig. 6 is a plan of the paper-holder slide.

The same letters of reference denote the same parts.

A represents the base-plate.

B B represent uprights at the ends a a, respectively,of the base-plate and projecting upward therefrom to bring their upper ends into position to support theguideCabove the front a of the base-plate.

D D, 8w, represent the series of punches. They are of the usual shape, are adapted to be moved vertically in the guide, are each upheld by a spring, E, and are adapted to be thrust downward by means of the lever F, which, when the handlefof the lever is depressed, forces the punch downward, and thereby effeet-s the perforating of the paper, which is held in the holder G above the dies H in the baseplate.

I represents the bar upon which the lever F turns and slides. It is conveniently upheld, as shown, in the uprights B B. The move ments of the lever are indicated by the broken lines in Figs. 1, 2, respectively.

J represents the frame which carries the paper holding and feeding mechanism. It is suspended from the bar I by means of the lugsjj, which encircle the bar at the ends,respectively, of the lever-sleeve f, and it is stayed in an upright position by means of the guide-bar K.

An upright shaft, L,is journaled in the frame at Z, and is provided with the ratchet Z and the gear I. The paper-holder G is attached to a. slide, M,which in turn is held at m and adapted to be slipped longitudinallythat is, in the direction of the length of the machine-in the frame J. The slide is provided with a rack, N, which engages with the gear 2'. The lever F is extended atf and is provided with the fixed projection f and the pivoted dog f which lastnamed parts coact with the ratchet Z. A coil-spring, P, whenever the ratchet is released, acts to effect the rotation of the shaft L and gear Z in the direction of the arrow as, Fig. 1. A spring, Q, serves to draw down the inner end of the lever F, and to bring the projection f out of and the dog f into engagement with the ratchet whenever the outer end of the lever F can rise.

The operation of the improvement is as fol lows: The paper R to be perforated is suitably inserted in the holder G to bring that part of the paper which is to be' perforated beneath the opening 9 in the holder. The slide M is then moved in the frame J into its posit-ion shown in the full lines in Fig. 1. This movement of the slide M, by means of the rack N and gear 2', effects the winding of the coilspring 1?, and but for the engagement of the lever-dog with the ratchet the slide, by reason of the tendency of the coil-spring to unwind, would return to its original position. (Indicated by the broken lines, Fig. 1.) The leverdog, however, prevents the return of the slide, and the entire sliding mechanism, including the lever, the frame J, the slide M, paperholder, and paper, is, by means of the lever, slipped upon the bar I until the lever is brought over that punch which it is desired to use, whereupon the handle end of the lever is depressed and the punch beneath it caused to act. In this position of the lever its projectionf is in engagementwith the ratchet Z, and the slide M remains stationary in the frame J; but as soon as the handle end of the lever is raised, as it must be in order to. depress another or even the same punch, the projectionf passes downward out of the plane of the ratchet. The coil-spring P then acts to move the slide M in the direction of the arrow as", Fig. 1, until the lever-dogf encounters the stopf The paper-holder moves with the slide N, and the paper in consequence is moved the proper distance for the next perforation, whereupon the lever is again moved to above the desired punch and again depressed, and the paper is shifted another space, and so on until the desired number of perforations has been made.

I claim a 1. The combination, in a perforator, of the sliding paper-holder G, held above the base plate, the slide M, to which the holder is attached, having the rack N, the gear Z connected with the upright shaft L, the frame J to which the slide is secured, and the lever F, extended at f having projection at f, the dog f, the ratchet Z, and the spring P, substantially as described.

2. The combination of the lever F, movable on bar I, the punches D, actuated by said lever, and the paper-holder slide provided with the rack, with the frame J, the shaft L, the gear I, the coilspring P, and escapement mechanism connected with said shaft, substantially as described.

3. The combination of the paper-holder slide provided with the rack, with the frame J, the shaft L, the gear Z, the coil-spring P, the ratchet Z, the lever F, extended and provided with the projection and dog, and the rod I, on which said lever turns and slides, and the punches D, each upheld by a spring, E, substantially as described. I

4. The combination of the paper-holder slide, the rack, the frame J, the shaft L, the gear Z", the coil-spring P, the ratchet Z, the rod I, the lever F, extended and having the projection and dog, the guide 0, and the punches D, each having a spring, E, substantially as described.
