To alt whoml t may concern.'

- Be it known that I, Lnwls A. Foo'rn a citizen of the United States, residing at Silver Creek, in the county of Chautauqua and State of New York, have invented a new and useful Improvement in Punching Tools, of which the following is a specification.

This invention relates. to punches or punching tools of the kind adapted for use in dating cards, tickets, papers or the like.

The objects of the invention are to produce a punching tool of this kind which is adapted to mark the day and month on an, article and which is of simplified construction so that the date can be easily changed; also to provide a' punching tool of this kind which can be locked so as to prevent the unauthorized changing of the date for which the tool is set; also to provide a punching tool of this kind with a stripper for removing the punched article from the dies which also acts as a finder to guide the articles into proper operative relation to the punch; also to so arrange the stripper that the same pinches or holdsthe article before the samey is punched; also to provide a punchingtool o f this kind with an improved arrangement of perforating pins or punches, whereby a comparatively small number of pins or punches will suiiice to datethe article; also to improve the construction of punching tools of this kind in other respects hereinafter specified.

In the accompanying drawings:v

Fig. 1 is .a side elevation of a punching tool embodying the invention.

Fig. 2 is a fragmentary sectional elevation thereof showin the jaws of the tool open.

Fig. 3 is a similar viewthereof showing the jaws closed.

Fig. 4 is a face view of the lower jaw or base plate of the punching tool.

Fig. 5 is a similar view thereof showing the stripper.` f

Fig. 6 is a transverse sectional view of the upper die or punch showing the means for locking the pins in place.

Fig. 7 is a fragmentary elevation thereof showing the end fof thenpper die.

A and yB represent two relatively movable parts or jaws of the punching tool, which jaws may be moved relatively to each other in any desired manner. In the construction shown, the handles C (f to each other at c. The outer ends of the handles are pivoted to the movable jaws at c c2 and are provided with pins c3 c* which are slldably arranged in slots c5 c in the ends of the jaws A and B. By means of this arrangement the jaws move toward each othr when the handles C C` are pressed toget er and are moved away from each other by means of the spring c7 which tends to open the handles and the jaws A and B. Any other means for moving the jaws toward and from each other may be employed.

The punch for marking the card, paper or other articles is arranged in the outer end of one of the movable members or jaws, and

comprises a plurality of pinsl D arranged in' holes l .in the upper jaw, in the construcaws are actuated by means of l whlch are pivoted relatively tionshown, and are adapted to'enter into holes E formed in the other jaw or base plate. The pins are removably secured in the upper jaw in any suitable manner so that they can be removed or otherwise rendered inoperative to vary the mark made by the punch. In the construction .shown for this purpose, each ofthe pins D' is provided with ahead d', and a slide F is arranged in the upper jaw adjacent to the heads of the pins to hold the same in place'. The slide 4 1s removably secured in the upper jaw, being, 1n the construction shown, adapted to slide sidewise out of engagement with the pins D so that the same can be removed from ,or placed into the upper jaw. Any other means for rendering any of the pins of the pincll1 operative or inoperative may be em p oye In order to facilitate the punching or perforating of the article, a stripper member G is preferably employed which, in the conf struction shown, consists of a stri of resilient material suitably secured to tli jaw, for example by means of a screw or rivet g, Figs. 1 and 5, and provided with an opening g" through'which the pins D are adapted to pass. The stripper member is arranged in close proximity to the lower jaw. forming therewith a slit g2 into which the card or other article to be punched or perfoe lower pins D are withdrawn from the article, thus from the punch after having been acted upon by the pins D. The hole g in the stripper member also servesy as a guide or finder whereby the article may be accurately positioned in the punching tool, so that the person using the tool can see beforehand where the perforations or impression will be made when the jaws are brought together. The stripper member G is preferablyprovided with a projecting portion g3 which extends into proximity to the upper jaw and which prevents the insertion of the articles at the wrong side of the stripper member.

Tn order to hold the article firmly on the punchin tool in an adjusted position, means are pre erably provided for pinching or gripping the article between the jaws before the jaws are closed sufficiently to cause the pins D to act upon the article. For this purpose, a spring H of any suitable kind is employed, one end of which engages the stripper member G and the other end of which engages the upper jaw A. The spring is preferably held in place by any suitable means, such for example as projections h L on the stripper member and jaw A respectively. The spring is so formed as to exert very little pressure against the stripper member when the jaws are opened, and .is made sti' enough to press the stripper member against the lower jaw B when the jaws are partly brought together. This will pinch the article between the stripper member G and the lower jaw and hold the same in place while the jaws are being brought together to perforate or Votherwise act upon the article. Y

Means are preferably provided for locking the slide F in the upper jaw in such manner that the arrangement of the pins in the punch cannot bechanged by unauthorized persons. Any suitabley lock may be employed for this purpose. Tn the construct1on shown, the lock Yprovided includes a bolt or the like li which is adapted to snap into a notchez' in the slide F when the same isin its closed position. The bolt can be withdrawn by means of a key adapted to be inserted into a key-hole t" in the upper jaw member A.

One of the main'uses of a punch of this Vare, arranged as in the construction shown,

five rows of holes d being provided, each row havin fivel holes in which the desired num ber op pins may be secured, these rows beare made on an article. The pins 'la k indi-y cate that the first two rows are used for indicating the month and that the last three rows indicate the days of the month, and also indicate the position in which the article was held relatively to the punch when marked, so that the correct reading of the date is ensured. Thus to indicate January only the first pin lc would be used, the other nine pins'of the first two rows being omitted. February would be represented by the first and second pins of the first row. October, the tenth month, would be represented by using the first pin la of thefirst row and the second pin of the second row,

Athis pin representing the character zero 'first pin k of the irst row and the first pinv of the second row, and December, the twelfth month, would be represented in the same manner as November except that ,the second pin of the second row would also be used. The same system of counting is used in connection with the last three rows which represent the days of the month, the third column being used to-represent the numeral of the lOs column when used in connection with pins in the fourth and fifth rows. Thus, for example, 28 will be represented byv the pin la and a pin in the third row above the pin c, and eight pins in the fourth and fifth rows, the insertion ofthe pins beginning with the lower ends of the rows.

By means of this system a large variety of numbers and dates can be indicated with the use of the minimum number ofl perforations in the card. This, in turn, permits the perforations to be made within a small space and thus permits theu'se of a comparatively small card or article in connection with instalment payments. By means of this construction and arrangement lit has been gfound that the date can be punched in a space as small as a? square having sides one quarter inch in length. This punch is particularly desirable for use in connection with Liberty Loan payments, where bonds are paid :for on weekly instalments.
