No. 568,454 8 Claims. (Cl. 234-98) ABSTRACT OF THE DISCLOSURE A paper punch is provided with a punch actuating plate which is slidable to be operatively effective, in different positions, with respect to different combinations of plural, fixedly located punches, and the paper punch, also is provided with screw means for effecting such sliding. Indicia and/or contrasting areas of said plate assume positions relative to openings in an operating handle of the device to indicate the spacing of holes to be punched at any given position of said plate.

This invention relates to devices for punching holes in paper and, more particularly, is directed to such a device which is readily adjustable for enabling it to be employed in simultaneously punching holes in various spaced relationships.

As such devices may be utilized for punching holes in sheet material other than paper, all references herein to paper should be understood to comprehend not only paper but all other sheet material capable of having holes punched therein by a device such as that which is disclosed herein.

An important object of this invention is the provision of such a paper punching device which may easily and quickly be adjusted or readjusted for punching holes in various spaced relationships.

Another important object is the provision of such a device having punch actuating means capable of selectively actuating various combinations of punches provided in the device.

Another important object is the provision of such a device having relatively few parts which may be assembled easily so that the device may be very economically manufactured.

Another important object is the provision of such a device having visible means indicating to the user the particular punches which the device is adjusted to operate.

Another important object is the provision of such a device which includes a waste tray for the reception of punched-out paper which tray may very easily and quickly be emptied and readjusted to its waste receiving position.

The foregoing and other more or less obvious objects are achieved by the present invention of which several illustrative embodiments are disclosed herein without, however, limiting the invention to those particular embodiments.

In the accompanying drawing,

FIG. 1 is a front elevational view of a paper punching device according to a preferred embodiment of this invention.

FIG. 4 is a longitudinal, generally vertical sectional view of the device substantially on the irregular line 44 of FIG. 3.

FIG. 5 is a top plan view of an operating lever employed in a device according to a second embodiment of this invention.

FIG. 6 is a front to rear vertical sectional view substantially on the irregular line 66 of FIG. 5, including a fragmentary showing of paper punching means with which the operating lever cooperates.

FIG. 7 is a fragmentary, vertical sectional View substantially on the line 7--7 of FIG. 5.

All parts of the disclosed devices are formed of suitable, relatively rigid material preferably steel or other suitable metal.

The first embodiment of this invention, illustrated in FIGS. 1-4, comprises an operating lever 2 hingedly connected by hinge studs 10 toward forward ends of end walls 4 of said lever to upright end ears 6 of a frame 7 carrying seven similar punch assemblies 8.

The punch-carrying frame 7 includes on its underside and toward the rear thereof an elongate spacing plate 12 which is rigidly integral with said frame as, for example, by being welded thereto. Said spacing plate is also rigidly fixed as, for example, by welding, upon a top plate 14 of a base 16.

The front edge of the spacing plate 12 is located approximately centrally in the device thereby providing, forwardly thereof, an elongate slot 18 into which one or more sheets x of paper may be inserted for the purpose of having holes punched therein. The forward edge of the spacing plate 12 serves as a stop to limit the extent of insertion of paper into the mentioned slot.

The base 16 is formed with a downwardly extending rear flange 20 and a downwardly and outwardly sloping front flange 22 so that the base is substantially hollow. A waste receptacle 24 is provided in the form of a bottom plate 26 formed with upwardly extending end flanges 28 which close the ends of the base 16, and curled front tongues 30 which extend freely within rectangular apertures 32 in the sloping front flange 22 whereby the waste receptacle 24 is hingedly connected to the base.

The bottom plate 26 is formed, also, with an upwardly extending rear flange 34 which frictionally and quite tightly engages the outer surface of the rear flange 20 of the base. The upper edge of the flange 34 is preferably flared outwardly at 34a to facilitate manual pivotal opening and closing of the waste receptacle 24.

The punch carrier 7 includes a flat bottom plate 36 to the underside of which the spacing plate 12 is fixed, an upwardly extending web 38 integral with the forward edge of the plate 36, and a flat flange 40, integral with and extending rearwardly of the upper edge of the web 38.

The device, as may best be understood from FIG. 4, is provided with seven paper cutting plungers or punches 42k, m, n, p, q, r, s, arranged in spaced relationship and in alignment longitudinally of the device. All these punches are alike, and they all are similarly mounted.

As may best be understood from FIG. 3, punch 42s, for example, is slidably disposed within vertically aligned holes 44a and 44b formed respectively in the flange 40 and in the flat bottom plate 36 of the punch assembly 8. The punch is formed with an annular recess or neck 46 in which is disposed a snap ring 48. A coil spring 50, encircling the punch, is compressed between the snap ring 48 and the plate 36 to hold the punch yieldably in its uppermost position, the movement of the punch to said position being limited by engagement of the snap ring 48 with the flange 40. The lower end of the punch may be dished to accentuate its paper cutting effect.

When the punch is in its uppermost position, as shown in FIG. 3, the slot 18 is clear or free to receive the paper x. When the punch is pressed downwardly in the manner hereinafter explained, it cuts through the paper x and continues downwardly into a hole 52 formed in the plate 14 in alignment with the holes 44a and 1), thereby completing the punching of the hole in the paper.

The principal feature of this invention resides in means carried by the operating lever 2, at its underside, for actuating selected ones of the punches 42k, in, n, p, q, r, s, to effect punching of the paper with holes spaced apart as desired.

The punch actuating means, designated generally at 54, comprise a relatively rigid plate 56 slidably held upon the underside of the operating lever 2 by a pair of studs 58, which, as shown, may be of the nature of double-headed rivets tightly seated within longitudinally aligned and spaced holes 60 in the operating lever and arranged with their necks extending slidably within spaced, aligned slots 62 formed in the plate 56'. Thus, the plate 56 may be slid longitudinally within the operating lever to the extent permitted by the length of the slots '62.

The plate 56 is bent to provide a plurality of longitudinally aligned, plunger actuating projections 64a, b, c, d, e, f, g, h (FIG. 4) which are generally U-shaped as shown, for example, at 64b in FIG. 3. These projections are of such various widths and so spaced that when the plate 56 is slid longitudinally between five different positions, different couples or groups of the mentioned projections will operate, when the operating lever 2 is manually pressed downwardly, to engage the upper ends of and operate dilferent combinations of the seven punches 42k, "5 17, q: S-

The sliding of the punch actuated plate 56 is accomplished by turning of a thumb screw 66. This thumb screw (see FIG. 4) has a manipulating knob 68 fixed to its outer end and, adjacent to said knob, the screw is supported for free rotation within a suitable hole formed in one of the end walls 4 of the operating lever. The threaded end 66b of said screw is threaded through a depending flange 70 provided at the corresponding end of the plate 56. Where the thumb screw 66 extends through the end wall 4 of the operating lever, it is suitably held against longitudinal movement as, for example, by means of snap rings 72 snapped into suitable annular recesses (not shown) formed in the thumb screw at opposite sides of the wall 4. Thus, manual rotation of the thumb screw 66 serves to slide the plate 56 in opposite directions to the extent permitted by the slot 62.

Colored spots 74a, b, c, d, e, f, g, and h are provided upon the upper surface of the plate 56; these spots being longitudinally coextensive, respectively, with the projections 64a, b, c, d, e, f, g and h as shown in broken lines in FIG. 4. The mentioned spots are in underlying alignment with indicator holes 76 formed in the operating lever 2 in longitudinal positions corresponding to the positions of the plural punches 42k, m, n, p, q, r, s. The arrangement is such that, in any adjusted position of the plate 56, colored spots will be visible through only those holes 76 which correspond to the punches then in operating relationship to their said actuating projections.

It may be seen from FIG. 4 that the punch actuating projections 64a, b, c, d, e, f, g, h, define spaces r, u, v, w, x, y, z, therebetween as well as clear spaces beyond opposite ends of the plate 56. When the operating lever 2 is pressed downwardly, the effect will be to depress and operate only those punches which are in vertical alignment with and underlie pairs or groups of the mentioned projections. Thus, with the plate 56 in its relationship to the punches illustrated in FIG. 4, manual operation of the operating lever 2 serves to actuate only punches 42k, 42p and 42s which, in said relationship, are operatively aligned with projections 64a, 64d and 6411. In said relationship, the other punches are aligned with spaces between projections on the plate 56, hence, they are not actuated.

The position of plate 56 as illustrated in FIG. 4 may be considered as a central position a on a scale which is applied to the drawing, above that figure, only for the present descriptive purposes. As viewed in that figure, the plate 56 may be moved longitudinally to the approximate extent shown in said scale either toward the left to bring the punch 42p into alignment with positions marked b and c on said scale or toward the right to bring the punch 42p into alignment with positions marked d and e on said scale.

It will thus be understood that the plate 56 may be shifted, by operation of the thumb screw 66, to five different operating positions with the punch 42p in alignment with the scale markings a, b, c, d, and e with the following results:

In a position, punches 42k, 42p and 42s will operate;

In b position, punches 42k and 42p will operate;

In 0 position, punches 42k and 42r will operate;

In d position, punches 42m and 42: will operate;

In e position, punches 42m, 42 2 and 42r will operate.

In a paper punching device as manufactured (not to the same scale as the drawing) the several punches may be so spaced that the device may be readily adjusted to provide any one of the five most used spacings between holes punched in paper; thus,

a position would provide three holes equally spaced 4% inches apart, i.e., 8 /2 inches between the end holes, this being the most used position;

b position would provide two holes spaced 4% inches apart;

c position would provide two holes spaced 7 inches apart;

d position would provide two holes spaced 2% inches apart;

e position would provide three holes equally space 2% inches apart, i.e., 5 /2 inches between the end holes.

The operating lever may be cut out as at 73 (FIG. 1) to expose indicia 75 on the sliding plate 56, said indicia, in conjunction with a pointer 73a formed on said plate at said out out, indicating the number of punches which f will operate in each of the five adjusted positions of said plate, and the spacing between the punches which are operative in each of those adjusted positions. This indicia arrangement enables a user to tell, at a glance, the direction and extent to which the plate 56 should be moved to change from one adjusted positioned to another.

It will thus be seen that a paper punching device according to this invention is readily adjustable to fulfill a substantial variety of paper punching requirements.

The second embodiment illustrated in FIGS. 5-7 differs from the first embodiment chiefly in the means by which the punch actuating plate may be shifted to adjust the device for punching differently spaced holes,

The second embodiment employs no thumb screw but instead, a punch actuating plate 56a is provided with a knob or handle having a shank 82 and a rivet head 84. The main part of the knob is disposed above and at least slightly spaced from the upper surface of the operating lever 2a and one portion of the shank 82 is very tightly held within an accommodating aperture 86 in the plate 56a so that the knob is mounted rigidly with respect to said plate. An upper portion of the shank 82 extends freely and slidably within a slot 88 formed in the operating lever in parallelism with an underlying line of punches.

The operating lever 2a is also provided with two guiding rivets 90 and 92 rigidly fixed thereto and extending slidably within aligned, longitudinal guide slots 94 and 96 formed in the plate 56a. The rivet 92 has a leaf spring 98 fixed to its bottom end and arranged so that opposite ends 98a and 98b frictionally engage the underside of the plate 56a to hold the latter frictionally in any adjusted position to which it may be moved.

The plate 56a, like plate 56 of the first embodiment, may be moved to five different punching-effective operating positions; and those positions may be indicated by five scale markings 100 on the top of the operating lever 2a, In that arrangement, the knob 80 may be formed with a pointer 80a to indicate, on the scale markings, the particular existing adjustment of the punch actuating plate It should be understood that the concepts disclosed herein may be utilized in various other ways without departing from the invention as set forth in the following claims.
