HAND PUNCH.

Application filed July 2,

The invention relates to punches, and particularly to hand punches, such as are usually employed by conductors, waiters, and others for punching tickets, cards, sheets, and the like.

A punch having some of the features and characteristics of the punch referred to in this application is shown and described in United States Letters Patent to Albert Beck, Patent Number 1,417,488, issued May 30, 1922. v

Male and female die elements are used in the punch of the invention of this applica tion, and it is a feature of the invention to r provide a guide, or bearing, for the male die pin which will assist in maintaining the male die pin in its proper relative position and accurately guide it, so that it will at all times properly cooperate and register With thel female die element.

It is another object of the invention to construct the guide, or bearing for the die pin so that the ticket, card, or sheet to be punched may readily be viewed and the point of application of the die pin easily and readily ascertained, thereby permitting the dies to be accurately applied to the desired place on the ticket, card, or sheet.

A further object of the invention is to construct the guide or bearing for the die pin so that it will permit the association with and operation of a lever With said die pin while the pin is in operative position g within the guide.

It is a further object of the invention to provide an arrangement of lever and die pin, or more particularly the connection of thel lever and the die pin. whereby the pin may be effectively operated in the guide or bearing and always be at right angles tothe female die element, and without any rotative movement of the die pin.

An additional object of the invention is to, preferably, form the body. grip, and lever r portions of the punch from sheet metal stampings, which are formed into proper shapes and suitably finished and assembled.

One of the objects of the invention is to construct the jaw of the punch. adjacent the die pin in such a -manner as to strengthen, support, and maintain the guide or bearing in its proper place in the jaw and, at the same time, close the end of the jaw between the sides thereof and the bearing to keep 1923.

In f h e `punch ofY ,the invention there is employed a `bodyportion lhaving a grip portion :1T .extending therefrom, the body portion 1,6 Ybeing termed to provide the jaws 18 and 119,' which are vseparated by a into which is inserted the ticket, card, o r .sheet to bepnnched. The jaws 18 and 1 9, respectively, carry the die cutting elements o fthepunch, i, e., thefmale punchdie pin 21 and the female die element .22. Thefdie iactuating lever 23, having the portion 2e, .is .pivotally secured to the l'pody lportion .through the medium of the pinf25. The lever associated with the piinchingv diefpin 21 `and is constructed so as to actuate the `die pin 21 and cause it'to be brought into co-operative relation with the female .die element,l22,`to punch the tickets, cards, and sheets, An expansion .spring y26 is arrangedbetween the lgrip portions 17 and 2e S0 that thegrip portions will normal'y assume an extended relation. One end the expansion spring is connected to the linger yring and the other cndrests y,against the inner portion oft' the grip 24.

' AThe'body portion 16, with its grip 17,`is formed o t a suitable blank, vwhich vis cut out oiiystamped in `a manner to provide the structure illustrated in Figures 1 and 2 when bent into shape. The blank is clearly shown When the blank is bent along the dott'e'dflines (0,?) it will provide 'the side portions of the vjaws 18 and 19.` The blank will then be `bent inwardly along the dotted lines c and (l and secured` together inv any suitable manner `and thus form a wall 28 oit Aa chamber 29, which is vproduced inthe lower jaw 19 of ,the This chamber is formed to hold the punchings 'from the tickets, cards, and

sheets. yTheblank illustrated in Figure 6 is cut out,l as indicated at 3()- and 31, which provides the opening 32 wheny the blank is bent into the shape shown in Figures 1 and 2. '1` he'opening thus formed provides a means through which vthe punchingeI from the tick- ,cts, cards, and sheets may ,be vdropped from the chamber'29. Vlien the blank is formed ,inl the shape illustrated in Figures 1 and 2 the

cutout portions

33 and 34 will provide theV slot 20. 'i

The blank is further provided with the aperture l35 and the -V- shaped .opening/36.` The aperture 35 provides a means for receiving the guide or bearing 37 for the die pin 21. The aperture 35 communicates with lthe V-shaped opening 36 .and provides a space which will permit the operator to view, the indicia which are punched from the ticket, card, or sheet. The provision of the openings described, together with the opening in the guide `or bearing 37, more particularly hereinafter described., assists 1n theaccurate application of thedie 21 to the ticket, card, or sheet. A plate 38 is suitably arranged in the

notches

39, 10 of the blank and secured therein. The plate 38 is apertured to receiye the guide or bearing 37. Y e

i The opening32, formed by the cut out portions 30. and 81, is closed .by a slidable closure Y' 4.1, which is bent to partially surround the ,lower jaw 19 ot' the punch and is provided with the inwardly extending flanges or lips 4:2 and 1-3, which extend intoand slide in `the slots or grooves .l/tand 4 5 in ythe op'w posite side walls of the chamber 29 of the jaw 1Q. The closure l1 is provided with an abutment 16 to liinit'the movement yoft the cclosure which engages the opposite extremities ot the opening 32 and limits-the move ment ot' the closure inbo'th directions. The construction ot the abutment 46 and vthe cut out 1.7 on each side of `the closure 41 tru-Irish means tomove ,the closure with relation to the jaw .19. The ,top and end walls yof the chamber 2 9 are formed by the plate 48 which is secured and held between 'theside walls ofthe chamber 29 andhas an aperture or vent 4:9. The plate 48 is provided with an aperture 50, into which eXtendsthe annu-lar flange ol the'texnalc cutting ,die 22.

The guide, or bearing, 37, .as clearly shown in Figure 7, ne'ferably,`is tubular andl designed to be mounted inthe aperture 35 inv the jaw 18 and the ,aperture in the plate It is held Awjth relation to the jaw 18 by being brazed or welded thereto. In

ion

lill

the brazing or welding process enough maf terial is used to completely close ythe end ofl jaw 18, vto ,the outer slot in the guide 37, thus providing

fillets

51, 51 between the outer slot the guide 37 ,andthe side walls of the .jaw 18, as illustratedin Figures 4 and 5. The` `

fillets

51, 51 not only assist' in strengthening, supporting, and .maintaining "the guide yor bearing in its proper place in the jaw, but prevent dirt, vdust and other Vforeign material 'from becon'iingy lodged inthe guide member and in the rear thereof and prevent interference with the die pin 21.v

llhe die actuating lever 3, vwith the grip .24, is' also formediof a suitable blank'which is cut out nor stamped so as to provide the structure illust-rated .in Figures 2 and' 9 when bentand pressed into shape.

The guide or bearing 37 is provided with an outer slot 52 which is arranged, when associated with the parts forming the punch, so that it coincides with the throat between the aperture and theV-shaped opening 36.

The bearing 37 is further provided with an inner, slotted aperture 53, through which one end of the die actuating `lever 23 is passed into engagement with the slot 54, which is arranged transversely to the length of and provided in the die pin 21. The transverse slot in the die pin 2l extends from one side of the die pin to the other, 180", or substantially so. This is clearly shown in Figures 2 and 3. The walls oit the slot or opening 54 in the structure illustrated in Figures l. and 2 are flared so that contact between thedie actuating lever and the wall of the slot in the die pin is provided during the movement of the die pin by the lever.

The construction of the female die element 22 is substantially similar to that' disclosed in the patent above referred to, except that it is provided with means whereby it may be moved into alignment with the movable die pin. To accomplish this the female die element 22 is provided with the elongated apertures and 56, which areformed to permit the

screws

57 and 58 to be passed therethrough and into engagement with a screwthreaded opening in the `member 48, which provides the upper wall of the `chamber 29. The arrangement described produces a means whereby the female die element 22 may be moved with relation to the male die pin 21 to cause the two elements to be brought into accurate alignment with each other.

In Figures 9 and 10 there is shown a modified construction ofthe grip lever and the die pin and also the means of connectin them to each other. The structure illustrate in these figures differs from that illustrated in Figures l and 2 in the connection between the lever 59 for actuating the diepinG() and the said pin. In this structure the flat rounded end of the actuating lever 59 is inserted into a slot 6l extending through the die pin 60 transversely of the length thereof. The walls of the transverse slot 6l, with which the rounded end of the actuating lever 59 engages, provide a contact betwen t-hc faces of the walls and the end portion of the actuating lever 59 so that the lever when operated will actuate the die pin 60. The guide or 'bearing 37 illustrated in Figure 7 is adapted to be used in connection with the structure of Figures l() and Il.,

From the foregoing description of the various structures, among other advantages, it will be mani fest that an eiiicientarrangement is provided for holding and maintaining the die pin in its proper relative position; that the die pin is always accurately guided throughout its entire movement toward and away from the female die element during the punching operation; that the die pin is always at right angles to the female die element; that the female die element may be adjusted to cause it to be aligned with the die pin and may be held in this last named position; that the die elements and the guide or bearing may be formed of relatively dif-- ferent material from that of which the body of the punch is formed, thereby substantially increasing the wearing qualities of thel punch, and that various means of connection between the die pin actuating element and the die pin may be employed.
