JOHN SIGWALT, JR., OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF HIS RIGHT TO CHARLES J. STROMBERG, OF SAME PLACE.

iIMPROVEMENT IN PERFORATING-STAMPS.

Specification forming part of Letters Patent No. 151,723, dated June 9, 1874; application filed December 23, 1873.

To all lwhom it may concern Be it known that I, JOHN SIGWALT, Jr., of

Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Perforatin g-Stamps, of which improvements the following is a full, clear, and

Figure l is a side elevation of a hand canceling-stamp embodying my improvements; Fig. 2, a top view of the platen; and Fig. 3, a vertical central section of the press or stamp. Like letters of reference indicate like parts. Tickets canceled or particularly designated by having printed matter stamped upon them are capable of being fraudulently altered by erasing such matter, and hand cancelingstamps, constructed to cancel or mark the tickets by pnnchin g them, have been employed for the purpose of preventing such alteration. My invention relates to the latter class of hand canceling-stamps; and consists in certain novel features, hereinafter fully described and particularly set forth, relating to the construction of the stamps, my object being to improve their operation.

- In the drawing, A represents the base of the stamp, and B is a yielding arm attached thereto. C is the platen or table which receives the tickets. 'lhe platen consists of the plate or disk a, made preferably of steel, and of the supporting-block a attached to the forward Aend of the base A. The plate a is attached to the block a', and is perforated, as shown at e. The perforations e e are arranged to correspond to the characters to be punched into the tickets, and may, for example, be so arranged as to approximate the word half, as shown in Fig. 2, thus indicating that the ticket so which is arranged over the platen. d d are punches projecting fromthe lower face of the block'D, and corresponding, in size, number,

and arrangement, to the perforations e c, the latterbeing just large enough to receive the punches. E is a yielding plate or stripper attached to the lower face of the blockD, and perforated to receive the punchesd d.

In' order to stampa ticket, it is arranged upon the platen so as to cover the perforations c e. The forward end of the arm B is then struck suddenly with sufficient force to drive the punches through the ticket. The small disks which are thus cut from the ticket fall into the channel e', and either fall away or may be readily relnoved. The plate E strikes Vthe ticket before the punches do, and yields to the continued downward movement of the arm B.

When the arm B is released the ticket isv pushed from the punches by means of the plate F, and drops upon the platen. The ticket is thus firmly held in place while beingpunched, and after it is punched it is entirely free from the stamp.

Having thus described my invention, what I claim as new, and desire tol secure by Letters Patent, is-

The yielding arm, terminating at its forward end in the head or block D, provided with the punches d d and with the yielding perforated plate or stripper E, in combination with the base provided with'a platen consisting of the perforated plate a and of the supporting-block a', having the channel e therein, substantially as and for the purposes specified.

JOHN SIGWALT, J R.
