This application is a continuation-in-part of US. Patent application Ser. No. 495,268, filed Oct. 12, 1965, now abandoned.

This invention relates to a ticket or check punch and more particularly to a ticket pun-ch which incorporates interchangeable punches and dies.

The ticket punch of this invention is constructed such that it is easily disassembled, thus enabling interchangeability of parts without special tools. The parts of the device are preferably coupled together using removable fasteners, clips and snap rings, in order to readily permit dies and punches to be changed, depending on the punch hole configuration desired.

The ticket punch device of this invention also features a receptacle which is positionable under the base to collect the punchings, as well as a slidably mounted gage for selectively positioning the material to be punched with respect to the punching mechanism of the punch device. The ticket punch of this invention additionally includes means for aligning the punching mechanism with respect to its mating die.

Accordingly, it is an object of this invention to provide a new and improved ticket punch device.

It is another object of this invention to provide a new and improved ticket punch device which may be easily disassembled without special tools in order to change the mechanism for forming the punch holes.

Another object of the invention is to provide a new and improved ticket punch device including a percussion mechanism for advancing a spring-biased punch on a cooperating die.

A still further object of this invention is to provide a new and improved ticketpunch device including a removable cap for collecting punchings and a slide for gaging the material to be punched.

An additional object of this invention is to provide means for aligning a punch with respect to its mating die.

Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.

The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the invention will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which FIG. 1 is a side elevational view of the ticket punch device according to this invention;

FIG. 2 is a sectional view taken along line 22 of FIG. 1;

FIG. 3 is a top view of a die plate according to this invention;

FIG. 4 is a side elevational view of the die plate according to this invention;

FIG. 5 is a top view of a the invention;

FIG. 6 is an enlarged side elevational View of a punch aligning and stripper mechanism according to the invention;

FIG. 7 is a top view of FIG. 6;

FIG. 8 is an alternate embodiment of means for aligning the punch with respect to its mating die;

FIG. 9 is another alternate embodiment of means for aligning the punch with respect to its mating die; and

FIG. 10 is still another embodiment of means for aligning the punch.

In FIGS. 1-7 there is illustrated the preferred embodiment of a ticket punch device which is suitable for use on a desk. The device includes a base 10 preferably of metal or other suitable material which is stamped, molded or formed in any suitable manner into the configuration shown in FIG. 2. Positioned on the base is a die plate 12, more clearly shown in FIGS. 3 and 4. Th die plate 12 includes a die 13 and a pair of

holes

14 and 15 which are aligned with a pair of holes 16 and 17 in the base. Mounted on top of the die plate is a punch holder 20 having a U-shaped end 21 with a pair of

holes

22 and 23. These holes also are aligned with

holes

14 and 15 of the die plate as well as the holes 16 and 17 of the base. The other end of punch holder 29 includes a second U-shaped portion 25 on which is mounted a punch 26. This punch is of a length such that it extends out wardly above and below openings 28 in the sides of U-shaped end 25. The openings 28 provide guides for the movement of punch 26 toward and away from the die 13. The punch 26 is slidably supported within the guides 28 by a spring 32 and a snap-type retaining ring 33. In order to depress the punch toward the die 13, a lever 40 is pivotally coupled by a pin 41 to a pair of sidewalls 43 which are preferably formed as part of die plate 12. It is to be understood that they may be formed as part of base 10, if desired. In order to couple the die plate, the punch holder and the base together, a plurality of removable fasteners 45 are provided. The fasteners are preferably of the type which may be removed, such that the die plate and punch holder may be readily detached and interchanged with other types of plates and punches if a change in the hole type being punched is desired. It is to be further understood that, if desired, rivets may be utilized in place of the removable type fasteners. However, the removable type fasteners are preferred for the purposes of this invention.

punch holder according to As part of this invention there is provided a member 49 which is attached to the U-shaped end 25. The member 49, in the preferred embodiment, has a material stripper portion shown at 50 with an opening 51 which permits the punch 26 to be movable therethrough. Upon activation of the punch by depression of the operating lever 40, the punch will travel through the stripper portion 50 to punch a hole in material positioned between the stripper portion 50 and the die 13. The punched-out material will then penetrate through die 13 and a hole 54 in the base and fall into the hollow portion of the base 10. The scrap is collected by a sliding reservoir cap or tray 55 which is preferably clipped to the front of the base so as to collect scrap which passes through die 13 and the opening 54 in the base 10.

The member 49 also includes an aligning portion 57 having a surface 58 which engages a guide means flat 60 formed on the punch 26. Thus the punch 26 will be prevented from rotating as the punch is depressed and the punch will at all times be aligned to its mating die regardless of the shape of the punch and the die.

In order to gage the depth of the material to be punched, a sliding depth gage 70, which snaps over the base 10, is provided. The gage permits the centering of the hole to be punched from an edge of the material to be accurately determined.

Referring now particularly to FIGS. 6 and 7, there is disclosed the punch 26 having a retainer slot 81 for mounting a snap-type retainer ring 33. After the punch is depressed by the action of the lever, the punch will return to its initial position by the action of the spring on the snap-type retainer ring 33.

To change the punch as Well as the die, fasteners 45 can be removed to permit a die plate of a different dimension die to be inserted. Furthermore, the punch 26 can be removed by snapping out the retaining ring 33. In this manner interchangeability of punches and dies is possible by the user, without the requirement-of special tools to disassemble the device.

Referring now to FIG. 8, there is shown an alternate embodiment of the aligning portion of member 49. In this embodiment a guide means keyway 62 is formed in the punch 26 and a tooth 63 is formed on the member 49 to prevent the punch 26 from turning.

FIG. 9 shows another alternate embodiment of the aligning portion of member 49. In this embodiment the member 49 is provided with an opening 65 having a flat therein for engaging a flat 66 formed on the punch 26.

FIG. 10 shows still another alternate embodiment of means for aligning the punch. As shown, the embodiment includes a punch holder 70 having a bore 71 and a counterbore 72 formed therein. A punch member 75 is positioned within the

bores

71 and 72. The punch member 75 has a flat 76 formed thereon for engaging a pin or, preferably, a set screw 77 supported by the punch holder 71. The punch is spring-biased upwardly by spring 78 engaging a retaining ring 79 supported by the punch 75.

It should be understood that the aligning means shown in each of the embodiments herein provides means for preventing the punch from falling out of the punch holder if the punch is turned on its back.

It will thus be seen that the objects set forth above, among those made apparent from the preceding description are efliciently attained and since certain changes may be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the foregoing description or shown in the accompanying drawing, shall be interpreted as illustrative and not in a limiting sense.
