Application September 4, 1937, Serial No. 162,554

- 17 Claims.

This invention relates to perforators of the class having a plurality of individualv leveroperating perforating elements selectively movable into alignment for simultaneously forming a series of perforated indicia in'paper or other easily pierceable material.

While marking for identification purposes may be effected in many ways, where it is desired to mark a series of papers, coupons, pages of abook, or like subject-matter with the same indicia, it is best effected by means of a perforator which punches a series of minute holes through the matter to be marked in the desiredwonfiguration. Advantages common to all of such con- 16 ventional perforating devices are that the identifying perforations may be made on most any part of the matter to be marked, e. g., over other printed matter, without weakening the legibility of either printed or punched characters, thus 20 obviating much of the usual care required in the disposition of printed indicia with respect to other printed matters; that the same indicia may be punched through a series of separably usable pages with a minimum of effort and time;

and that numerous printing accessories necessary to many other conventional marking means and methods are entirely dispensed with.

It is a general object of the present invention to provide a device embodying the above noted advantages, characterized by more expeditious operation and wider scope of utility.

A more specific object is the provision of a perforator structure'having a plurality of perforating characters selectively movable into operative position for individual or simultaneous use whereby one or a series of perforated characters may be punched during a single stroke of a manually actuated lever.

Another object is to provide a series of per- 40 forating elements carrying wheels revolvableto bring the perforating elements into alignment with supporting means for matter to be perforated by means of a lever, in combination with means to increase rotary 'velocity of said wheels with respect to the lever.

Another object is to provide novel means for manually moving a supporting table against a series of perforating elements including a toggle joint connection to enable the attainment of maximum pressure between the table and the perforating elements.

Another object is the provision of the structural combination of means to drive matter to be perforated on aplurality of pins to form a perforated configuration, and a stripper mechanism for removing said matter from the pins at the conclusion of the perforating operation, the manual actuation of both of said perforating and stripping mechanism being augmented by the tension of a spring extended by preliminary I movement of the means for actuating said stripper and pin driving mechanism. 7

Another object'is to provide a gage for fixing the extent matter to be perforated may be admitted into a recess under the perforating pins, 1 said gage having means employed therewith to secure it in any adjusted position, whereby matter successively marked will be perforated at uniform distances from its margin.

Another object is to provide, in a device of 1 the character above designated having a supporting table for matter to be perforated and a plurality of perforating pins, of means for assuring alignment of the perforating elements carried individually by revolvable wheels for use simul- Q0 taneously, comprising a latching device for the means adapted normally to compel the movement of the supporting means and pins in performing their perforating operation, said latching device being actuated by the misalignment of any of the 85 perforating elements with respect to the supporting table.

Another object is to provide a perforating element comprising a series of pins mounted in a laminated back, combining strength in use with 30 ease of assembly and economy of manufacture.

Other objects and corresponding advantages such as simple, positive operation, efficient utilization of parts, replacement of worn parts, and durability, will be apparent to those of skill in the art from an examination of the following description read in the light of the accompanying drawings, in which: i

Fig. 12 is a plan view of matter perforated by the present invention;

Fig. 13 is an enlarged view of one of the perforating pins.

each of said supporting walls is reentrant to form the ends of a perforating-recess H. A curved back cover l8 (Fig. 3) is secured at its bottom edge to the rear bar H to inclose the back of the perforator between walls i5 and H5. The upper end of back cover i8 is secured to a pair of blocks mounted on a transverse rod i9 having its opposite ends mounted in walls i5 and I6. A slotted index plate 2| provides an extension of the cover It being secured by screws or the like to blocks 28 at its upper end and.- extending to the front of the perforator for attachment to blocks 22 carried on a transverse rod 23, which in turn is mounted in holes of the opposed walls l5 and 16. An extension plate 24 is similarly secured to blocks 22 and defines the upper edge of the perforating-recess. An oblique front plate 25 is secured to the foremost bar l4 and extends upwardly into the recess i1. 26 indicates a reinforcement plate (Figs. 4 and 5) bolted rigidly to each supporting wall adjacent the perforating recess.

A horizontal arbor 21 is journalled at its opposite ends in centrally disposed bearings of walls l5 and I6. 0n arbor 21 a plurality of wheels 28 are rotatably supported, carrying the perforating elements later referred to in detail. The

wheels 28 are individually revolvable on arbor 21 and being separably operable in use, it will be apparent that any number of such wheels may be utilized, depending upon the number of individual perforated configurations which the device is adapted to make simultaneously.

A series of flat shoes 29 (Fig. 9) are formed equi-spaced apart on the periphery of each wheel, the outer .face of each shoe being disposed at .right angles to a radius of wheel 28 through its center. Perforating elements, generally designated at 38 are mounted on all but one or any group of said shoes, each element comprising a laminated back 3|. A series of holes are punched transversely in each lamination 32, separately, of the back 3| in the form of the desired configuration which the element is to perforate, as for example, a letter or a numeral. Laminations 32 are then assembled one on the other with the punched holes aligned ,and a pointed pin 33 is driven through each of the seriesof aligned holes to frictionally retain the laminations together, and hold the pins rigidly parallel with respect to each other. The laminations and pins may be soldered or otherwise secured immovably together. The backs 3| of the elements are secured to shoes 28 respectively, by means of screws or the like, with the pointed ends of the pins 33 extending outwardly from the respective wheels.

Each wheel 28 may accordingly be rotated to bring any of the perforating elements carried thereby to a position adjacent the perforating recess and in vertical alignment with the arbor 21 by means of a control lever 34 (Fig. 3), pivoted at its inner end on arbor 21 adjacent the wheel it is adapted to control and extending radially outward through an aligned slot 35 in plate 2|. On the outer end of each control lever 34, a split handle 36 is mounted by means later referred *to. A spur gear 31, located parallel to and between each control lever 34 and the wheel it is adapted to actuate, is pivoted on the lever 34 intermediate the ends thereof so as to mesh with a spur gear. 36 concentrically and rigidly mounted to the adjacent wheel. In the vertical plane of each set of spur gears 31 and 38 under and adjacent the plate 2|, a ring gear segment 39 having inwardly-extending gear teeth 40, is provided to mesh with the side of spur gear 31 opposite to the point thereon of the mesh of said gear withspur gear 38. The ends ofring gear segment are mounted on rods l9 and 23, adjacent ends of respective segments, being separated by blocks 20 and 22 and suitable spacers (not shown).

To prevent the teeth of spur gear 31 from slipping out of mesh with the teeth 48 of the gear ring segment, the outer end of each control lever is longitudinally slotted as at 42. A member 43 is retained in each of slots 42 between the bifurcations '44 (Figs 4) of the split handle 36. The handle, member 43 and control lever are held in position by means of a screw or the like extending through the handle and member. The lower inner end of member 43 is bent at right angles across the gear ring segment between the same and plate 2|, and thence downwardly on the side of the segment 33 opposite to that on which the lever is disposed, whereby each gear segment is held between, respectively, a lever 34 and an adjacent member 43 to prevent its lateral displacement with respect to the teeth of spur gear 31. Wheels 28 are thus geared with the handles 36, and with the latter against the upper end of slots 35, the unoccupied shoes 29 will be at the bottom of the wheels. in vertical alignment with the arbor 21 and adjacent the perforating-recess I1. The position of handles 36 with respect to indicia of an index carried on the face of plate 2| is correlated with the position of the perforating elements with respect to the perforating-recess, as will be obvious to those of skill in the art. The ends of the slots 35 limit movement of the control levers and correspondingly the opposite ends of the oscillatory movement of the wheels 28.

A pair of inclosing outside plates 46, supported on base l3 cover the walls l5 and I6 (Fig. 6). Arbor 21 extends through plates 46 and is threaded on its ends for nuts 41 which hold the plates 46, supporting walls i5 and I6, and mechanism therebetween, including wheels 28, gears 38 and 39, and control levers 34 in the above described operable association.

Below the wheels 28, a vertically movable table 48 forming the bottom of recess i1 is supported, by means hereinafter described in detail, for the support of matter to be perforated, as for example, a book of coupons" (Fig. 12). Table 48 comprises a horizontal channel member 50, in vertical alignment with arbor 21. A supporting plate 5| having a downwardly extending flange 52 bolted or otherwise secured to the side of channel member 50 forms a part of table 48 between the upper edge of channel member 50 and the upper edge of the front plate 25. A

aroaavv wooden block 53 is slidable between the side walls 54 of member 58 and flush with the upper edges of said walls providing a cushion for the pins 33 of the perforating elements Ill when the table is moved against the pins as hereinafter described. The side walls 54 of channel member 50 are longitudinally grooved at 55 as are the adjacent walls of block 53. A U-shaped wire 55 having its ends extending into the adjacently aligned grooves of the walls 54 and block 53 keys the block in member 58. The ends of themember 50 are extended into closely fitting vertical recesses 51 formed in the supporting walls l5 and I6 and in reinforcement plate 28, which guide the table 48 in its vertical movement. The bottoms of the recesses 51 limit the downward movement of the table.

The table is raised from the bottom of recesses 51 by mechanism about to be described, which is actuated manually by means of a handle 8 keyed to the outer end of a shaft 59 extending through supporting wall I5 and the adjacent inclosing wall 46. The opposite end of shaft 59 extends through and is journalled in supporting wall it. Shaft 59 is connected to a pair of pins 60 journalled in projections 8| integrally formed on the underside of channel member 58 by means of a toggle joint mechanism which consists of a bifurcated arm 62 secured rigidly on shaft 59 intermediate walls I5 and 15, carrying a pivot 63 parallel to shaft 59. .A connecting arm 64 having one end journalled on pivot 53 has its opposite end pivoted to one end of a toggle 65. The opposite end of toggle 65 is pivoted on a shaft 56 journalled in supporting walls l5 and IS. A pair of toggles 61 are pivoted to toggle 55 intermediate the ends thereof and extend across a line through the points of pivot of the ends of toggle 85, being pivotally connected to pins 50, journalled in table 48.

It will be apparent that upon the partial rotationof shaft 59 effected by drawing the handle 58 downwardly that theconnecting arm 64 will be moved rearwardly due to the eccentric position of the pivot 63 with respect to the shaft 59. This movement of arm 54 swings toggle 65 on its pivot on rod shaft 66, raising and moving rearwardly the point of pivot of the toggles 61 thereon. As the table 48 is restrained from lateral movement by the portions of the supporting walls I5 and I6 forming the recesses 51, the elevation of toggles 51 causes ,upward movement of the table urging the paper on the table, onto pins 33 of the perforating elements 30 to form the perforations 58 in thematter 49.

To assist this operation, and particularly to counteract the increasing pressure of the handle 58 necessary to drive the paper to be perforated onto the perforating pins, a radial arm 69 (Fig. 5) is keyed to the end of shaft 59 which extends through supporting wall l6.'- A coil spring I0 (Fig. 8) having one end pivoted to supporting wall It as at II directly above shaft 59 is attached to the free end of the radial arm which, with the table in its lowermost position, extends forward slightly below the horizontal. As the shaft 59 is turned upon movement of handle 58, the spring III will be extended until dead center is reached, i. e., with the axes of the spring and arm 69 parallel, which will occur after less than one-half of the approximately 90 of movement of the handle 58. The counteraction of spring I0 will, during the remainder of the stroke of the handle, accordingly be eflective in urging the elevation of the tableand perforation of the material operated upon. Thys'pring II will similarly assist in affecting a complete return of the handle to its original position, and accordingly facilitate the operation of the stripper mechanism about to be described.

The stripper for removing the perforated material from the pins 33 comprises a hub I2 mounted rigidly on a transverse tube I8 journalled in opposed supporting walls I5 and I5 in substantially horizontal alignment with the perforating recess I'I. Secured integrally with the hub and extending into the recess II in vertical alignment, respectively, with the areas between different pairs of wheels 28, are a series of spaced parallel stripper tongues I4. The forward ends of tongues I4 are turned upwardly to guide the material to be perforated between the lower edges of the tongues and the table 48. A return'bar I5 is secured rigidly to the bottom of the hub I2, by any means well known in the art, with its free end extending under the channel member 50 between projections 5|. A spring finger I8 secured in tube I3 on the outside of the supporting wall It is sprung under a pin 11 secured to,

said supporting wall, said finger being bent in a counterclockwise direction from the point of its attachmentto the tube I3 whereby the finger will urge like counterclockwise movement of the hub tongues I4 to follow the table, thus removing the Y perforating material from pins 33.

I8 indicates a variable gage limiting the depth of the perforating recess [1 to provide an abut ment against which material to be successively inserted into recess II for perforation may be held, and thereby insure its uniform perforation with respect to the margins thereof. Gage I8 is carried in recess II to the rear of channel member 50 and below stripper tongues I4 by a rod I9 secured. to its middle at right angles thereto. Rod I9 extends slidably through a hole bored through hub I2 substantially parallel to'bar I5. The hole 80 through the hub intersects the bore of tube I3. A coil spring 8i, having one end secured to the underside of bar I5 and its opposite end' connected by means of a downwardly projecting finger 82 secured to the rearward end of rod I9, urges by its tendency to compress, therods I9 and gage I8 to a foremost position. The gage 18 may be held in any adjusted position by means of a retaining pin83 of the table except when such alignment is effected. A transverse rod 85 has its opposite ends carriedrigidly in supporting walls I5 and It between wheels 28 and the upper end of rear cover l8. On rod are pivoted a series of restraining arms 86. Arms 86 extend rearwardly and downwardly to a position with their free ends normally overhanging a stop bar 81 mounted at the rearward side of shaft 59 to the arm 62 and parallel to said shaft. The contact of bar 81 with the free ends of the restraining arms 86 will accordingly prevent rotation of the shaft by which the perforating operation is motivated. A pivot rod 88 is journalled in the supporting walls l5 and i6 above the lower ends of arms 86. A control plate 89 is secured to pivot rod 88 and extends obliquely upward, being normally supported substantially parallel to the arms 86 by means about to be described. A right angle extension 98 of the control plate 89 is formed with a plurality of parallel slots 9| (Figs. 6 and 8) in which individually the arms 86 are maintained against lateral displacement. A plurality of adjusted screws 92 extend loosely through, respectively, each of a series of holes in the upper end of plate 89' aligned respectively with arms 86. Each screw 92 is threaded tightly into the bore of a coil spring 93 which springs have their opposite ends attached respectively to the arms 86. The tension of springs 93 on the arms tends to draw the lower ends of the arms free from engagement with the bar 81, permitting the shaft 59 to be turned without restraint. A cam 94 is mounted rigidly on shaft 59 adjacent supporting wall l6 on which a follower lever 95 rides having its opposite end pivoted on rod 88. A portion of the follower-lever 95 is extended above rod 88 for the support of a transverse pin 96 adapted to bear against the control plate 89 intermediate rod 88 and the attachment of springs 93 thereto, whereby rotation of the shaft 59 and cam 94 causes the lower end of the cam follower to be moved laterally from the axis of the shaft, utilizing the rod 88 as a fulcrum to tilt the plate 89 rearwardly on the axis of rod 88, resulting in the extension of springs 99, so as to increase their tension as the shaft 59 is moved downwardly and thereby increase the tendency of the springs to draw the arms rearwardly on rod 85, for a purpose hereinafter more in detail described.

The shoes 26 heretofore referred to, forming the support for the perforating elements 99, are slightly wider than the thickness of wheels 29. A rider 91 secured to each arm 86 by means of a rigid laterally extending member 98 engages the underside of the overhang of shoes 29 on each wheel 28 and holds the respective arms 98 forward to a position contacting the bar 91 to block operative movement of shaft 59 and handle 58. The space between shoes 29 on each wheel 28 provides notches 99 into which the riders 91 drop, when aligned therewith, in response to the'tension on the arms 86 of respective springs 99 thereby moving the lower end of the arms 86 rearwardly and out of the arcuate course of the bar 81 upon movement of shaft 59. The riders 91 contact each notch 99 successively as the perforating elements 99 are moved into vertical alignment with the wooden block 53 of the channel member 59. When the wheel-operating handles 36 are moved to the desired index numeral or letter on the face of plate 2|, and riders 91 are drawn into respective notches 99 between certain of the shoes 29, depending upon the rotative disposition of the wheels 28, the shaft 59 may be turned manually by means of the handle 58, causing the cam 94 carried thereby to tilt plate 89 and increase the tension of springs 98 as above described. Thus, the tension of the springs 99 will resiliently hold the riders 91 in the centers of notches 99 to resist tendency of the wheels 29 to become misaligned either before or during perforation of the matter acted upon.

It will be apparent, however, that to turn wheels 29 the riders must of necessity leave the notches 99, i. e.,' in order to ride on shoes 29, which operation, as above noted, draws the arms 86 forward, b i ging the lower ends'thereof into alignment with the line of movement of stop bar 81. Conversely, the table-elevating movement of shaft 59, when the riders are centrally located in notches 99, causes the bar 91 to move into alignment with the lower ends of arms 98 to prevent their inward swing, i. e., toward the shaft, incident to the movement of the riders from, notches 99, thereby locking wheels 99 and the perforating elements "in aligned position throughout the perforating and return strokes of handle 59.

While we have described but one embodiment of our invention, it will be apparent that many of the structural features of our invention may be omitted or substituted by conventional expedients, but that such separable features are both individually and combinatlvely part of the present invention; and further, that numerous changes in shape, number, size, and proportion of the various parts may be made herein all without departing from. the spirit of our invention as defined in the appended claims.
