Application filed October 9, 1928. Serial In. 140,48t

This invention relates to machines for performing upon paper or other fabric, and more particularly to improved means for punching apertures in paper or perforating 5 paper and for perforating and punching paper at the same operation.

In some businesses, such as the business of supplying stationery for use with manifolding machines, the paper strips after being in printed upon are punched and perforated to provide apertures in each form of the strip and perforations are provided between adjacent forms. The perforations and the punch holes cooperate with each other in the manifolding machine, for the punch holes determine the tearing-oif positions of the strips while the perforations define the tearing-off points on the strip and assist in the tearingoif operation. Hence, it is extremely desirao able to have the punch holes and the perforations always accurately placed with respect to each other.

I Heretofore, the operation for punching the apertures in the paper and the perforating operation were performed separately at points remote from each other, and this, due to stretching of the web and mechanical slippage and misadjustment, has caused considerable difficulty, for in such case the perforations and the punch holes would not have their fixed desired relationship with respect to each other.

An object of the present invention is to provide means whereby the punch holes and the perforations for each form may be made concurrently and at a single operation so that they will always have the desired fixed relationship. This is accomplished by providing a unitary structure for simultaneously punching and perforating each form.

The problem which has been solved by the provision of the means disclosed herein, was rendered more diflicult because, while the desired relationship between the punch holes and the perforations must remain fixed for a particular job, yet, the distance between the perforations and the punch holes is not standard. There are, however, two such distances which are practically standard.

Accordingly, the present invention provides a perforatin device and its su port in such a way that fiy reversing the per orating device on its support, either of these two standard distances between the perforations and the punch holes can be had.

A still further object of the invention is the provision of means for mounting the crforatlng unit upon its support so as to old 1t to and prevent it from moving upon the support.

And a still further object is the provision of means for adjusting the perforating de- 'vice so as to vary the extent of movement of the perforator which consequently varies the width of the minute perforations.

And yet another object is to provide for universal adjustment of the punching units relative to each other and as a whole parallel to and transversely of the direction of travel of the printed web.

Other objects and advantages will hereinafter appear.

In the accompanying drawings which illustrate the form of the invention at present preferred- 75 Figure 1 is a schematic side view of a printing press showing the device of the present invention as applied thereto.

Fig. 6 is aplan view of a portion of a web of paper showing the perforations and punch through the line 99 of Fig. 3, showin the punching and perforating unit adjuste' according to the standard shown in Fig. 6.

Referring now to Figs. 1 and 2 so that a suficient understanding of the printing ress may behad to a preciate and .understan the application of t 0 present inventlon thereto,

,a web of unprinted paper is led from a supply roll 21 over a guide 22 under a dancin roller 23 between guide rolls 24, 25, 26 an?! 27 and over a platen 28 where the paper is printed with the desired form. From the platen 28, the printed web 29 is guided over aguide roller 30 to the feed mechanism 31 located at the delivery end of the press. The

guide rollers, platen and feed mechanism are all mounted on the bed 32 of the press.

Between the guide roller 30 and the feed mechanism 31, the present invention provides a punching andperforating unit 33, having a base portion 34 and ahead 35.

Referring to themechanism shown in Fig. 2, the bed 32 of the press supports a main drivesha-ft 36 having a pitman 37 connected toa movable head 38 for the press which carries the type form 39 into cooperation with the platen 28. The main drive shaft 36 is provided with a cam 37a, for cooperation with a' cam'arm 38a mounted on a square shaft 390 carried by bearings 40 in the bed 32. I

- The uare shaft 39a is provided with an' arm 41 s idabl mounted'thereon and adaptedto turn wit the shaft. This arm 41 carriesja universal 'oint 42 connected to a link 43 which in turn asa universal joint 44 connected to an arm 45 mounted on an operatin shaft 46 of the combined perforating an punching head 35 which will be described hereinafter. v

Thus, when the main drive shaft 36 operates, the type form 39 is brought into engagement with the platen 28, and in the proper sequence the shaft 46 is rocked by its connetion with the arm 38a and the cam 37 a on the main drive shaft "36.

Heretofore, perforation of the forms was accomplished at the same time that the forms meoaoee were printed, the perforating rules being carried in the printing form 39, and the punching device was located somewhere between the guide 30 and the feed mechanism 31 With this previous arrangement, there was a large free stretch ofprmted webs 29 between the punching device and the platen which frequentl caused the registration, or proper s acing etween the punch holes and the per orations to var Such variation was, of course, extreme y undesirable and troublesome, because in some manifoldin machines the tearing-ofi' point, was defineby the perforations while the stopping of the strips 1s predetermined by thepositions of the punch holes.

The present invention avoids these disadvantages by providin means for concurrently perforating an punching the strip and performing both these operations at the same place in the travel of the printed web 29.

Referring now to Fig; 6, the printed web 29 is provided with prlnting for the separate forms 47. After passin through the punching and perforating devlce the head of each form is provided with punch holes 48 and perforations 49, the punch holes being used for aligning and paper stopping purposes in the manifoldin machine and for binding purposes after t e forms have been written upon, and the perforations 49 being utilized to facilitate the operation of transversely folding the strips when making a packet and severing of the strip into form lengths when being used. The distance Y (Fig. 6) between the centers of the punch holes 48 and the line of perforations 49 represents a standard dimension for a particular kind of work, and as stated, it is extremely important that this distance .be kept accurate and constant in all the forms so that the tearing-01f operation will surely take place along the line 49 and not either behind or ahead of it.

In Fig. 6, the leading form 47 is shown as perforated and punched, but the other two forms are unperforated and represent the form of the web before it reaches the punchin and perforating device 33.

ile the distance Y, shown in Fig. 6, is standard for a particular kind of work, there is another standard distance for different and important kinds of work. This is shown in Fig. 7, in which a distance X is left between the line of perforations 49 and the punch holes 48. The distances X and Y being correct for the majority of manifoldin machines the production of either kind 0 work in asingle printing press is greatly facilitated by the present invention by the provision of means whereby the mere operation of reversing the perforating device will cause either dlstance X or distance Y to be provided between the perforations and the punch noles. Hence, according to the present in vention, it is no longer'nccessary to expend considerable time and labor in setting-up preparatory to the production of the different kinds of work.

Referring now particularly to the punching and perforating unit 33, reference being had to Figs. 3, 4, 5, Sand 9, the present invcntion provides a frame which is mounted on a base 51 held to the bed 32 of the press by releasable clamp 52, the bed of the press at this portion constituting rails and the clamp 52 permitting the bed of the perforating and punching unit 33 to be slid along to desired position. This longitudinal adjustment of the punching and perforating unit 33 is provided for the accommodation of forms of different lengths and permits the punching and perforating unit to be located at the proper point for operation in con-. nection with all sizes of forms within the limits of the press. To enable it to operate the head 35 in the various adjusted positions referred to, the arm 41, which operates the shaft 46 of the punching and perforating unit, is allowed to slide on the square shaft 39 being fixed in the desired adjusted position by means of a set-screw 410:.

In order to permit lateral adjustment of the frame 50 of the punching and perforating unit, cooperating guides 53 and 54 are provided on the frame 50 and the bed 51 respectively, and an adjusting screw 55 having its head 56 anchored to the frame 50 by a saddle 57 and itself mounted in an extension 58 on the bed 51 moves the frame 50 either to the right or left as seen in Fig. 3, according to the direction in which it is rotated. The adjusted screw 50 is locked in desired position by means of lock-nuts 59.

Thus it will be seen that the punching and perforating unit 33 may be adjusted either longitudinally of the press or laterally of the press to bring the punching and perforating unit into the desired location with regard to the printed web 29.

The frame 50 of the punching and perforating unit 33 has upwardly extending arms 60 for supporting the movable portions of the punching and perforating unit and also the operating shaft 46. The movable portion of the perforating and punching unit comprises. a head 61 having angular bearings 62 adapted to ride in V-shaped grooved bearings 63 inserted in the extending arms 60 of the frame 50. It is upon these bearing surfaces 62 and 63 that the head 61 rides up and down in operating to punch and perforate the paper. Movement is imparted to the head 61 for this purpose by means of an eccentric cam 64. This cam 64 is located in a saddle or yoke 65 having upper and lower bearing surfaces 66 and 67 for engagement with the cam 64 so that as the shaft 46 rotates, the head 61 is reciprocated riding on the bearings 62 and 63.

' The punches 68, for producing the punch holes 48 are mounted in an angular bar 69 shaped to fit snugly against part of the under-side and part of the side of the head 61, see Fig. 9, with the top of the punch 68 in contact with the under-side of the head 61. There is an angular bar69 for each pair of punches 68 (see Fig. 5) and this bar is adjustable along the head 61 transversely of the direction of feed of the web, and a clamp 7 0 located in an under-cut groove 71 in the head 61. The clamp comprises a screwthr-caded portion 72 and a flanged nut 73 by means of which it may be tightened to firmly draw the bar 69 against the head 61 and hold it in place. Since the under-cut groove 71 extends the entire way across the head 61, the bar 69 for each pair of punches 68 may be brought into the desired position with regard to the printed matter of the form 47 merely by loosening the nut 73 of fhe dclamp 70 and sliding the bar along the iea This transverse adjustment of the punching device with regard to the head 61 and with regard to each other is extremely advantageous, for frequently the punch holes 48 of different forms are located in different positions laterally with respect to each other, and hence in a single operation forms of different characters or Width may be punched. Then, if when setting up the press the position of thewvb with respect to the punches is not quite right, the entire gang of punches may be moved laterally by manipulation of the screw 55.

Below each set of punches 68, there is provided a punch block 74 having cutting dies 75 for cooperating with the punches 68. These punch blocks 74 are adjustable in the same manner as the bars 69 for the punches 68, and, of course, in making the adjustment care must be exercised that the dies 75 in the punch blocks 74 are located beneath the punches 68 in the bars 69.

The perforating operation is performed by a perforating knife 76 held in a bar 77 extending transversely across the frame 50 so as to operate upon the entire width of the web 67. The bar or frame 77 for the perforator 76 is shaped to fit closely against the head 61 and the bottom of the angle bar 69 for the punch and is held in this position against movement laterally of the unit by means of wing-nut 78 carried by screw 79 threaded in the head 61.

In order to adjust the bar 77 which carries the perforator 76 vertically for the purpose of increasing or decreasing the depth of the perforations or to make the depth that desired, the bar 77 has threaded in it an adjusting screw 80 having a finger-piece 81 located above a saddle 82 and a disk 83 located below .the distance between the perforator the saddle 82. The saddle 82 is screwed into the head 61 so as to have a fixed positiontherein. When it is desired to raise or lower the perforating unit, the win nuts 78 are loosened to rmit free up-an -down movement allowed by the elongated slots 84 in the bar 77 through which they pass, and then the finger-piece 81 is rotated to move the bar 77 up-and-down as desired. When the perforating unit has been properly adjusted, the adjusting screw is locked in desired position by a lock-nut 85 and then the wing-nuts 78 are secured in place to hold the perforating bar as adjusted.

The perforator 76 is held in adjusted position firmly against the bar 77 in a longitudinal groove 86 therein by means of a wedgeshaped bar 87 secured in place by screws 88 which carry the wedge-shaped bar up to the groove 86 and. firmly hold the perforator 76 therein against any possible movement. It will be noted that the perforating unit 76 is not located directly in the center of the bar 77, and also that the bar 77 is made exactly the same on both sides. The groove 86 in the bar 77 is so located that when the bar 77 is placed on the head 61 in the position shown in Fig. 9, the punch and perforating unit is set up to provide the distance Y between the centers 0 the punch holes 48 and the line of perforations 49. When, however, the wing-nuts 78 and screws 79 are removed, the bar 77 may be taken off the head 61 and reversed, thus bringing the perforator 76 to the position shown in Fig. 8 where 76 and the punches 68 is the same as the distance X. Hence, when the punching and perforating unit is being set up the bar 77 is so placed on the head 61 that the perforating member 76 is either in the position shown in Fig. 8 or in Fig. 9, according to whether the distance between the punch holes and the perforations is to be distance X or distance Y.

It will be noted that when the screw 88 is set in place, it draws the bar 87 upwardly and hence jams the perforating unit 76 firmly against the side of the longitudinal slots in which it is located.

A block 89 which is located under the perforating unit 76 and acts as a purchase for the paper during the perforating operation is mounted on the frame 50 by means of screws 90. The frame 50 is provided with two holes 91 and 92 into which the screws may be set. When the frame 77 for the perforator is set up, as shown in Fig. 8, the

screw 90 is placed in the hole 91, and, in this position, the apertures 93 in the block-89 are directly beneath the perforating device 76. When, however, the perforating device 76 is set in the position shown in Fig. 9, the screw 90 is placed in the hole 92 in the frame 50, so that the apertures 93 will be then directly under the new position of the perforating I device 76.

For the purpose of causing the perforatgr to be withdrawn from the perforations 1n the web 29, which the perforator makes therein, a stripper bar 94 mounted on guide screws 95 sliding in clampin bar 87 is provided with a s ring 96 whic causes the stripper bar 94 to normally located below the lower edge of the perforating device 76. When the head 61 moves downwardly to cause the punch and perforator to operate, the stripper ar 94 engages and firmly holds the web 29 against the block 90 while the perforating device 76 pierces the paper. As'the head 61 rises, the perforating device 76 is withdrawn from the perforations in the paper while the stripper bar 94 is yet in contact with the block, and hence the perforating device 76 is completely withdrawn from the paper. During the subsequent upward movement of the head 61, the stripper bar 94 is removed from engagement with the paper b reason of the engagement of the heads 9 of the guide screws 95 with the bottom of the slot in which they are located.

The punches 68 are likewise provided with means for assuring that the web 29 is not drawn upward with the punch. For this purpose, they are provided with strippers 98 mounted, as shown in Fig.8, on guide pins 99 and are provided with springs 100 for holdin the stripper bar 98 in operative position. The guide pins 99 are mounted in the angular block 69 which carries the punches 68 and each block 69 has its own stripper, so that no adjustment of the stripper need be made when adjusting the block transversely of the direction of feed of the web. The strippers 98 operate in the same manner as the strippers 94.

It will thus be seen that the present invention provides universal adjustment for the punching and perforating device and provides a simple and easy means of producin diiferent distances between the punches and the perforator, so that two standard kinds of work can be done on the same printing ress with very little labor and time neede for shifting over from one kind of work to the other, and no special set-up operation being required.
