2 Claims. (Cl. 164100) This invention relates to paper perforating and has special reference to an attachment for a rotary printing machine arranged to perforate forms printed on such a machine.

More particulary the invention relates to a device for perforating check forms printed on a rotary printing machine and fed therefrom to the present device.

The principal object of this invention is to provide a perforating device which may be attached to and detached from a rotary printing machine so that the printing machine may produce imperforated sheets when used without the present device and, when combined with this device, printed and perforated sheets.

Another object of this invention is to provide a rotary perforating device which may be attached to a rotary printing machine and driven therefrom.

A further object of the invention is to provide a perforating attachment for rotary printing machines particularly adapted for producing the longitudinal and transverse rows of perforations used in sheets having a plurality of check forms printed thereon.

Still another object of this invention is to provide a novel perforating attachment for rotary printing machines wherein provision is made for adjustment of the perforations to properly register with the printed matter.

Yet another object of the invention is to provide a novel device for the aforesaid purpose in which the actual perforating elements are removable and replaceable so the elements may be used for different shapes, sizes, and spacing of perforations.

Still further the invention provides means for adjusting the perforating elements in such manner as to secure proper perforation to suit the grade and thickness of the material being perforated.

With the above and other objects in view, as will be presently apparent, the invention consists in general of certain novel arrangements of details and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly claimed.

In the drawings like characters of reference indicate like parts in the several views, and:

Fig. l is a side elevation of this invention showing the application thereof to a printing device of the rotary type,

Fig. 10 is an enlarged fragmentary sectional detail on the line 1010 of Fig. 3, and

Fig. 11 is an enlarged fragmentary detail sectional view taken on the line 11-11 of Fig. 1.

In the construction of the perforating device as here disclosed, there is provided a pair of frame sides 10 which are held in fixedly spaced relation by certain cross or tie bars presently to be described. This perforating device is arranged for connection to a printing machine of the rotary type a fragment of which is but shown in Fig. 1 at 11. It will be seen that the printing device includes a gear 12, side frames 13 and tie rods 14 and 15. The printing device also is provided with a pair of delivery rolls 16 for delivery of the printed sheets to the perforator. It is not deemed necessary to explain the details of the printing machine any further as this perforating machine is applicable with minor changes in the specific structure of the attaching means, to a wide variety of printing machines.

Each of the frame sides 10 is provided with a bearing hub 17, the hubs being axially alined and supporting a hollow shaft 18. A hollow upper cylinder 19 is located between the frame sides 1d and has one end reduced as at 29, the reduced portion being provided with a flange 21. The cylinder is provided further with cylindrical end portions 22 of the same diameter as the hubs 17 and the cylinder and its ends has a snug but revoluble fit between the inner faces of the hubs 17. The cylinder 19 has its end portions fitted tightly on the shaft 18. Fitted on a cylindrical portion 22 is a gear 23 which engages against the flange 21 and is fixed thereto by suitable means such as the rivet 24. Revolubly mounted on the portion 22 beside the gear 23 is an adjustable gear 25 which is of the same pitch diameter as the gear 23 and has the same number of teeth. In the gear 23 there is formed a slot 26 and an arm 27 is riveted to the gear 25 and projects through the slot. The arm 27 lies between two lugs 28 positioned on the gear 23 adjacent respective ends of the slot 26. Extending in alinement through the lugs 28 are adjusting screws 29 provided with lock nuts 30. The points of the screws engage on opposite sides of the arm 27 and by adjusting the screws 29 the gear 23 may be rotationally adjusted with respect to the gear 25.

Projecting from the frame side 10 adjacent the gears 23 and 25 are stub shafts 31 whereon are meshing idler gears 32 connecting the gear 12 operatively with the gear 25.

On the cylinder 19 is mounted a pair of blade carrying sleeves each having an outer end 33 and an inner end 34. Between the ends 33 and 34 of these sleeves is positioned a segmental perforating blade 35. Screws 36 having their heads countersunk pass through the ends 34 and through the blades 35 to have threaded engagement with the ends 33, the screws having the double function of holding the ends of the respective sleeves to each other and of securely clamping the respective blades 35 in position.

Extending longitudinally of each sleeve section or end is a slot 37, the slots all being in alinement. Extending from one end to the other of the two sleeves is a carrier bar 38 which fits closely in the slot 37 which, it will be noted, extends into an internal rib 39 in the cylinder 19. This bar 38 has a perforating blade 40 swaged or otherwise fixed therein adjacent one side of the bar. The bar is provided with notches 41 extending inwardly of the cylinder from the outer face of the bar and holding screws 42 extend through the notches and engage in the rib 39 as shown in Fig. 8. The screws 42 urge the bar inwardly of the cylinder 19 but in order to limit such inward movement adjusting screws 43 (Fig. 7) are threaded through the bar and engage against the bottom of the slot 37.

In opposite ends of the hollow shaft 18 are mounted plungers having bodies 44 provided with reduced and terminally threaded extensions 45 which project out from the ends of the shaft 18. Adjacent each end of the shaft 18 there is provided a pair of diametrically disposed slots 46 which extend longitudinally of the shaft. Opposite the slots 46 the wall of the cylinder 19 is provided with similar slots 47. Extending through each pair of corresponding slots 46 and 47 is a guide pin 43 which has a diameter such that the pin fits slidably in said slots. The inner end 49 of each pin is reduced and threaded for screw engagement in the plunger body 44. The outer end of each pin is provided with a head 50 countersunk in the sleeve section 33 so that the sleeve is secured to the plunger 44 to move therewith. The ends of the shaft 18 are internally threaded at 51 and in each threaded end is screwed a bushing 52 having an enlarged knurled head 53. The inner end of each bushing engages against the shoulder formed at the junction of the plunger sections 44 and 45. On the threaded end of each plunger is screwed a lock or jam nut 54 which bears against the head 53. It will now be noted that the rotation of a bushing 52 eifects longitudinal movement of the respective sleeve 33, 34 on the cylinder 19.

Cooperating with the upper cylinder is a lower cylinder 55 having reduced ends 56, the cylinder and its reduced ends fitting between frame hubs 57. Revolubly mounted in the frame hubs 57 are sleeves 58 having heads 59 provided with notches 69 for the application of a spanner (not shown). Extending radially of each hub is a set screw 61 arranged for engagement with the surface of the sleeve 53 to secure it against revolution. in the sleeve 53 are bored alined bearing holes 62, these holes being eccentric with said sleeves. A shaft 63 is journaled in the bearing holes 62 and on this shaft is fixed the cylinder 55. On one of the cylinder ends 56 is fixed a gear 64 which meshes with the gear 23 of the upper cylinder 19. The upper and lower cylinders are of equal diameters and the gears 23 and 64 are of equal pitch diameters. The eccentric adjustment of the shaft 64 enables the space between proximal portions of the two cylinders to be varied to accommodate paper of various thicknesses and the eccentricity of the shaft 63 is of such slight extent as not to interfere with the proper meshing of said gears 23 and 64. Dovetailed into the cylinder 55 are circumferential wear plates 65 and a longitudinal wear plate 66. Each of the frame sides has an arm 67 provided with a pair of bearing bosses 68 and 69, the bosses of one arm being axially alined with the bosses of the other arm. In one of the bosses 68 is journaled a stub shaft 70 whereon is mounted an idler gear 71 which meshes with the gear 64. The bosses 69 support a shaft 72 whereon is mounted a roller 73. This roller 73 has fixed thereon a gear 74, the roller thus revolving in the same direction as the lower cylinder 55 and forms the lower take-out roll. The frame sides are provided with oppositely disposed bearing bosses 75 wherein are mounted the ends of a shaft 76. On the shaft 76 is mounted a pair of sleeves 77 which are held fixed in adjusted postion by set screws 78. Each of these sleeves carries a pair of arms 79 between the free ends of which are revolubly mounted a flanged roller 80 the flange of which tends to engage the roller '73. A spring 81 is wound around one end of the shaft 75. This spring has one end hooked over an edge of one of the frame sides (Fig. 3) and its other end is fixed to a collar 82 adjustably mounted on said shaft 75. This spring urges the rollers 89 into engagement with the roller 73. Tie rods 83 connect the lower front portions of the frame sides and serve also to support a jogger, a portion only of which is shown at 84.

A paper guide 85 is pivoted between the frame sides at 85 in such position as to receive sheets of paper from the rolls 16 and deliver them successively between the upper cylinder sleeves 33, 34, and the lower cylinder 55.

In order to secure the perforating device to the rotary 4 printing machine, arms 86 extend rearwardly from the lower rear parts of the frame sides and have downwardly opening hook ends 87 adapted to engage over a tie rod such as 15 of the printing machine. The upper parts of the frame sides are connected by a tie rod 88 on which is rockingly mounted a slide 89. This slide 89 extends upwardly from the rod 88 and is provided with an opening 90 extending at right angles to the rod 88. Slidably mounted in the opening 90 is an arm 91 prolonged rearwardly from the slide and provided at its rear end with a forwardly opening hook 92 adapted to engage around an upper tie rod 14 of the printing machine. The forward end of the arm 91 is threaded as at 93 and on this end is screwed a thumb screw 94 having a reduced boss 95 which abuts against the forward face of the slide 89. Mounted on the upper end of the slide 89 is an inverted U-shaped yoke 96 having a short leg 97, which rests on the slide, and a long leg 98 which engages on the boss 95. A thumb screw 99 extends through the yoke and has threaded engagement in the top of the slide 89 so that when the screw 99 is screwed down the leg 98 will forcibly engage against the boss 95 and prevent rotation of the adjusting screw 94. Obviously the center of gravity of this invention will lie well forward of the support 15, the device thus tending to rock downwardly. This tendency is resisted by the arm 91 and the adjustment of the arm 91 is thus used to bring the gears 12 and 32 into proper meshing relation. However, to prevent any accidental movement of these gears into too deep engagement the frame sides are provided with set screws 100 which bear against suitable parts 101 of the printing machine and act in opposition to the arm 91. Lock or jam nuts 102 engage on the set screws 100 and prevent the latter from accidently getting out of adjustment. By adjustment of the parts above described this perforating device may be given proper adjustment in a fore-and-aft direction. In order to aline the invention laterally with the printing machine the frame sides 10 are provided on their rear edges with integral horizontally disposed yokes 103 each of which straddles a frame side 104 of the printing machine. These yokes carry opposed set screws 105 by manipulation of which the perforating device may be shifted bodily in a lateral direction with respect to the printing machine. When properly adjusted lock or jam nuts 106 serves to prevent accidental movement of the set screws, stability of such adjustment being thus secured.

When the perforating device has been bodily adjusted in both directions as above described a printed test form is fed through the perforating device. If now the per forations effected by the blade 40 are found to be too greatly out of proper registration with the printed matter on the test form, the set screw 99 is loosened and the nut 94 backed olf until the gear 32 is disengaged from the gear 12. The gear 32 is then rotated to an extent deemed proper to bring the perforations of blade 40 into proper position, the nut 94 is screwed up and a second test sheet is run through. If still the blade is too greatly out of position, the gears are again disengaged and the gear 32 adjusted. This action is repeated until the perforations of the blade 40 are at least close to the proper place whereupon the set screw 99 is screwed up and the nut 94 held against rotation. If now the blade 40 is still not in exactly proper position the jam nuts 30 are loosened and the screws 29 are manipulated to alter the relative positions of the gears 23 and 25 until the blade 40 is exactly in proper registry with the printed matter on a test sheet. The jam nuts are then screwed up. At this time, however, it may be found that one or both of the blades 35 do not register properly on a test sheet. Any blade 35 which is out of proper position is then adjusted by'loosening the nut 54 and manipulating the screw 52 to adjust the sleeve member 33, 34 until a test sheet shows the blade 35 to register properly. The nut 54 is then screwed In order to accommodate the device to the thickness of paper being used, the set screws 61 may be loosened and the bushing or sleeve 58 revolved to move the eccentrically held ends 56 and cylinder 55 toward or from the sleeves 33, 34 until proper adjustment is obtained upon which the screws 61 are screwed up. To set the blade 40 for proper depth of perforation the screws 42 and 43 are manipulated until the desired extent of perforation is obtained.

As here illustrated the perforattng device has been shown as particularly adapted to the perforation of bank check sheets arranged to provide a stub and a set of these checks. It is to be understood, however, that modifications may be made wherein other forms, such, for instance, as sales or order slips, bill forms and the like may also be produced. Furthermore, it is to be noted that the blades 35 and 40 may be modified to produce any size and shape of perforations, to efiect rouletting or even to form cutting knives. In fact, the device is capable of many modifications and it is not desired to limit the invention to any particular form or use but to include all such as come within the scope of the appended claims.
