TICKET-PUNCH.

SPECIFICATION forming part of Letters Patent No. 320,785, dated June 23, 1885.

(No model.)

To (LZZ whom it may concern:

Beitknown that I, XVARREN HILL,of Boston, (Cambridge,) in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in TicketPunches, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention is in the nature of an improvement upon that set forth in the Letters Patent No. 230,129, granted to me July 20, 1880, for ticket-punch.

In said patent the jaw carrying the female die was provided with a Stripper formed of wire secured to said jaw, and designed to prevent the punched ticket from clinging to the punch on its backward stroke. The ends of the wire of which the stripper was made were bent downwardly at right angles, and secured in holes formed transversely through the jaw by set-screws. By my present improvement this bending down of the wire ends is obviated, and the transverse perforation, and consequent weakening of the jaw, is avoided. I extend the wire ends longitudinally into the shoulder or hub of the jaw adjacent to the pivot, and secure them in any suitable manner.

My former patent also showed the arms of the wire -stripper parallel to each other throughout their entire length, and far enough apart at all points to permit the male die to work freely between them without contact with either arm. In using the implement on very thin paper, especially where the die was of angular or irregular form, the ticket was liable to cling to the male die or punch, and be drawn up between the arms of the stripper, and thus be torn or mutilated. By my pres ent improvement this difficulty is overcome by bringing the stripperarms nearer together in front and in rear of the dies than they are at and around the dies, so that the arms Show an outward swell to afford room for the punch to operate, and a contraction of the space between them at other points to insure a perfect clearance or throwing-off of the ticket after it is punched.

In the drawings, Figure 1 is an elevation of a punch embodying my present improvements. Fig. 2 is a like view, made partly in section.

Fig. 3 is a plan of the stripper and part of the lower jaw, a portion of the hub of the latter being in section. Fig. 4 is a perspective view of the stripper detached, and Fig. 5 a cross-section through the lower jaw at .r in Fig. 1.

A and B are respectively the upper and lower jaw of my ticket-punch, united by the screw-pivot E.

C is the male die or punch, fixed in the end of the jaw A, and D is the female die, correspondingly set in the jaw B.

F is a spring set in recesses between the jaw-levers, and serving to keep the jaws normally open.

G is the stripper, formed of a single piece of wire bent centrally, as shown, to form two arms, which are, at their extremities, fixed firmly in perforations in the hub H, so as to project longitudinally outward therefrom in a plane about parallel with the sur face of the jaw B. The outer face of said hub forms a shoulder or stop, J, below the stripper to regulate the extent to which the ticket may enter. Just beyond the dies the outermost portion of the stripper is turned up to serve as a guide in introducing the ticket properl y. between them.

The arms of the stripper lie nearer together and may be about parallel with each other, except at the point K, where each has an outward swell, as in Figs. 3 and 4, to avoid contact with the male die. The arms curving outwardly and again inwardly at this point are elsewhere near to each other, and thereby insure clearance of even the thinnest tickets from the exterior of the male die 0. There is, however, space enough between the stripper-arms to enable the operator to see the posit-ion of the figures on the ticket which he desires to punch out.

I claim as my invention- 1. In a tieket-punch, the pivot-ed jaws A B, provided, respectively, with the male die 0 and female die D, the jaw B being constructed with the hub H, in combination with the stripper G, formed of a single piece of bent wire having its ends inserted longitudinally in the hub H, substantially as set forth.v

2. The jaw A, carrying the male die 0, and

the jaw B, provided with the female die D, r

in combination with the wirestripper G, bent, name to this specification, in the presence of as shown, to form two adjacent arms curved two subscribing witnesses, on this 18th day of outwardly, as at K, to inclose the die, and April, A. D. 1885. lying nearer to each other at each side there- 5 of, substantially as and for the purpose set \Vitnesses:

WVARREN HILL.

In testimony whereof I have signed my C. G. KEYES.
