4Related applications The invention disclosed herein is, in some respects, an improvement over the invention disclosed in my copending application, Ser. No. 556,394 filed June 9, 1966, now Patent No. 3,387,526.

Background of the invention This invention relates to paper punching devices having means for changing the relative positions of punches to adapt the device for punching plural holes at various desired relative locations along a marginal portion of paper.

In devices hitherto designed, only partial means were provided for altering the relationship of punches, such partial means involving adjustment of a punch head itself so that a punch therein would be deactivated.

Summary of the invention The principal object of this invention is the provision of a paper punching device in which punch members may readily be moved to different positions, for punching differently spaced holes, without removing any punch member from the device.

For that purpose, this invention provides plural punch assemblies, slidably mounted on a manually rockable, longitudinally grooved, punch actuating rod, each assembly including a punch, a lever actuated lby rocking of said rod and coacting with the punch to actuate the latter, and detent means for holding the assembly in adjusted position on said rod.

Brief description of the drawing The drawing illustrates a preferred embodiment of the invention without, however, limiting the invention to that particular embodiment. In the drawing:

FIG. 1 is a front elevational view.

FIG. 2 is a plan view, an operating handle portion being omitted.

FIG. 3 is a rear elevational view, an operating handle portion being omitted.

FIG. 4 is a somewhat enlarged, end elevational view as seen from the right side of FIG. l.

FIG. 5 is a similarly enlarged, vertical sectional view 3,469,486 Patented Sept. 30, 1969 Description of the preferred embodiment The principal parts of the device disclosed in the drawing are a main base 10 having, toward the rear thereof, substantially similar, upstanding end walls 12, a rockable operating rod 14 borne horizontally in said walls and having an integral, upwardly extending operating handle 16 for rocking said rod, plural punch assemblies 18, carried upon said rod between said walls and slidable to various adjusted positions on the rod, an elongate, notched plate 20 extending through said assemblies in slidable relation thereto for holding said assemblies in adjusted positions and a paper positioning guide bar 22, slidably carried by the base 10, forwardly of the punch assemblies.

Each punch assembly 18, as best shown in FIG. 5, comprises a body 24 formed with opposed side walls 26, a top wall 28, and a bottom wall 30, and a punch assembly base 32 upon which the body 24 is fixed by rivets 34 with an intervening spacing plate 36 providing a paper receptive space x. The operating rod 14 extends, with a close fit, through aligned holes in the side walls 26, and bottom surfaces of side walls 38 of the base 32 slidably engage parallel ridges 40 formed on the main base 10 and extending substantially throughout the width of the device between the latters end 4walls 12. The rod 14 and the ridges 40 prevent material angular movement of the assembly 18 about said rod while permitting the assembly to slide freely sidewisely of the device.

Each punch assembly further comprises a vertically slidable punch member 42 carried in vertically aligned holes 44 in walls 28 and 30 and yieldably urged to its uppermost or inactive position, shown in full lines in FIG. 5, by a coil spring 46 compressed between wall 30 and a suitable washer 48 retained in a transverse slot in the punch member or otherwise suitably fixed to the latter.

A rockable cam plate 50 is carried on a horizontal stub shaft 52, the ends of which are suitably mounted in the side walls 26. The cam plate is formed with an upper edge 54, a front portion of which abuts the underside of wall 28 to limit clockwise turning of the cam plate as viewed in FIG. 5. A forward portion of the cam plate is formed with a pair of jaws 56, 58 -under the latter of which the washer 48 engages to limit the upward movement of punch member 42. A second washer 60, similar to washer 48, is fixed to the punch member 42 in position to extend -between the jaws 56, 58.

The cam plate 50 is formed with a rear portion havinga substantially oval, cut out 62, its ovular configuration being interrupted by an inwardly extending nose 64 which coacts with a longitudinally extending groove 63 formed in the operating rod 14. The rod 14 extends within the cut outs 62 of the cam plates of all the punch assemblies 18 in the illustrated relation to the nose 64.

When the rod 14 is rocked counterclockwisely, as viewed in FIG. 5, by operation of the handle 16, the cam plate 50 is rocked about the stub shaft 52 by the nose 64 to cause the jaws 56, 58 to push downwardly upon washers 48 and 60 and, thus, push the punch member 42 downwardly to force its sharp edged lower end through paper in space x and at least partially into a punch hole 68 formed in top wall 70 of the punch assembly base 32. The last mentioned, punching position of member 42 is shown in broken lines in FIG. 5. The handle 16 is operated against the force of spring 46 and the latter pushes the punch member 42 back to its uppermost position upon release of the handle 16.

The several punch assemblies 18 can be shifted to various adjusted positions along the rod 14 to enable the device to punch holes in various spacing arrangements along a margin of paper inserted into the space x. It is important, however, to provide for locking the assemblies 18 in adjusted positions. This is accomplished by cooperation of a spring-pressed detent or latch member, provided on each assembly 18, with the notched plate 20.

The back of the body 24 of each punch assembly 18 is open; and in that open area is disposed a rockable detent element 72 having a narrow back wall 74 extending to the top of the assembly 18, and similar, opposed, spaced side walls 76 (only one being shown). The detent element 72 is rockably supported at its lower end by a stub shaft 78, borne in the side walls 26 of the punch assembly near the bottom, rear portions of those walls.

The side walls 76 extend upwardly at opposite sides of and free of the cam plate 50 and also are clear of the operating rod 14. Said walls are enlarged at their upper ends and are formed with aligned slots 80 which are in approximate alignment with somewhat similar aligned slots 82 in side walls 26 of the punch assemblys body 24.

The notched plate 20 (FIGS. 5 and 6) extends freely within the slots 80 and 82 of all punch assemblies 18 with its ends close to the inner faces of the devices end walls 12 to prevent material shifting of said plate sidewisely of the device. The front edges of the plate 20 is provided with plural notches 84 at all locations on said plate where the punch assembly may possibly be located in any desired combination of punching adjustments to which said assemblies may be slid along the rod 14.

The slots 80 may be identical so that front edges 80a thereof may engage with couples of notches of the plate 20, or an edge 80b of one of the slots 80 may be cut back, as shown in broken lines in FIG. 5, suiciently to be inoperative as a detent, leaving edge 80a as the sole detent in the punch assembly for engagement within a notch 84 of the notched plate 20.

A torque spring 86 is coiled about the stub shaft 78 with one of its ends pressing downwardly upon wall 30 or upon a rivet 34 in said wall, and its other end pressing outwardly upon back wall 74 of the detent element 72 to urge the latter clockwisely (as viewed in FIG. 5) about said shaft. Thus, the spring holds the detent edge or edges 80a, 80b yieldably within related notches 84 and slightly shifts or holds the plate 20 against the rear edges of slots 82. sheet 90 in a suitable channeled receptacle 92 which is The notched plate 20 preferably carries an indicia suitably fixed upon the top surface of the plate 20. This indicia sheet preferably carries indications `of sets or pairs of holes which may be punched by this device after suitable adjustment of the locations of the several punch assemblies 18. Thus, for illustration, the indicia sheet includes representations of three hole locations 94a, 94b, 94e, the three punch assemblies 18 being shown .as disposed at said locations in FIG. 2. The detent element 72 has an open top through which the indicia 94a, 94h, 94e are visible between the side walls 76 of the detent element so that the user may readily ascertain that proper location of the punch assemblies has been effected for causing the desired hole spacing in paper 4being punched. Although reference has only been made to 94a, 94b, 94C, other somewhat similar indicia for indicating different hole spacings appear on the indicia sheet 90 as indicating means for reference in adjusting the punch assemblies to other desired punching positions.

The paper positioning bar guide 22 is conventional and a button 88 which operates means (not shown) for locking the gauge bar in any adjusted position also is conventional.

It is desirable that the device be adjustable not only for punching three holes but also for punching only 4 two holes. For that purpose, cut-outs 96 are formed toward the center of the rod 14 to interrupt the latters groove 63, and indicia 96a are included upon the indicia sheet 90 in positions thereon corresponding to the positions of said cut-outs. When one of the punch assemblies 18, usually the center one, is adjusted to a position corresponding to either indicia 96a, the nose 64 of the cam plate of that assembly is clear of any operative portion of groove 63 and is unaffected by rocking of the rod 14; thus said punch assembly remains inoperative.

Shifting of the punch assemblies 18 to desired positions for effecting a desired combination of spacing of punched holes is easily effected by the operator by pressing the top of detent element 72 forwardly against the force of spring 86 to release the edges 80a and/or 80b from engagement with any notch in the notched plate 20, thereby permitting the assembly to be slid bodily along the rod 14 to its desired position, whereafter, release thereof by the operator enables the spring 86 to rock the detent element 73 rearwardly to cause the edges 80a and/or b to engage within opposed notches 84 to hold the assembly against shifting from its adjusted position.

As in all hand operated paper punches, the length of the handle 16 has a ybearing on the punching capacity of the device. In the subject device, however, its punching capacity is substantially increased not only by providing a relatively long handle but by transmission of the operating force of rod 14 to the punch member 42 through the cam plate 50 rather than by the conventional arrangement for direct coaction of the rod 14 or equivalent operating means with the punch member 42. The cam plate 50, as illustrated, provides a substantial mechanical advantage which, if desired, may be increased by slight forward shifting of the fulcrum of said plate and/or by suitably revising the relationship of the rod 14 with the back end of the cam plate.

Those familiar with paper punching devices will readily understand that the concepts involved in the subject device may be utilized in various ways other than disclosed herein without departing from the invention.
