Patented Feb. 3, 1931 UNITED STATES PATENT OFFICE JOHN Q. SHERMAN AND ALBERT METZNEB, F DAYTON, OHIO, ASSIGNORS, BY DIRECT AND MESNE ASSIGNMENTS, TO THE STANDARD REGISTER COMPANY MANIFOLDING MACHINE Application filed October 28, 1928. Serial No. 143,724.

Our invention relates to the provision in manifolding machines for the retention of a record in the shape of individually severed form slips which are manifold copies of the form slips issued from the machine.

While there are other types of manifolding machines, the particular type which we have illustrated is one in which printed form strips are fed over a writing table Where notations are made thereon, either by hand or by a typing machine or stamp, the notations on the upper strip being transferred through to the lower ones collated therewith so as to produce as many copies as desired. The lowermost copy is the one which is normally retained as a record within the machine while the remaining copies are issued.

It is the object of our invention to provide a means of tearing off of the record strip during each feeding operation of the machine, an individual form length of said record strip, and of feeding the individual or separated forms into a suitable storage compartment within the casing of the machine.

The form strips in machines of this type usually are perforated or weakened at the end of each form so as to facilitate tearing it off from the remainder of the web held in the machine, and in the particular device of our present invention we provide means for grasping the record strip and tearing off the terminal form thereof, this operation taking place during the operation of feeding the next set of forms from the one of whichthe record was taken.

Among the objects of our invention is the provision of a tearing ofi means which operates as the hand of an operator would act in manually tearing oif a form of'paper by a gripping of the desired form, and applying a pulling motion first at one corner and then across the whole line of cleavage, there being means for holding the web fast during the operation of tearing off. I

It is our object further to provide for this action by a rotary as distinguished from a reciprocating member, and to arrange the mechanism so as to operate automatically each time the feed of the machine is given a complete movement sufiicient to issue a single set of forms.

We accomplish our objects by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings Figure 1 is a plan view of the mechanism used according to one of our modes of operation for tearing off a record web in form lengths for permanent storage within a manifolder.

Figure 2 is a detail side elevation of the parts shown in Figure 1.

Figure 3 is a plan view of another type of tearing off device.

Figure 4: is a side elevation thereof.

Figure 5 is an end elevation of the paper clamp of this modification.

Our invention has been shown as applied to the autographic register generally shown and described in United States Letters Patent to Sherman and Metzner No. 1,541,285 granted June 9, 1925. We have illustrated only the

side frames

1 and 2, the feed shaft 3, and feed pin wheels and

cams

4 and 5 respectively, and have confined our invention and the drawings to those parts used for tearing off the paper web. The writing table 5 of the machine extends beyond the feed point above the feed pin wheels, and from its end the record web 6 is delivered to the tearing oif device and storage feed.

A lower driven roll 7, cooperating with a spring pressed idler roll 8 receives the record web from the end of the writing table, and a lower driven roll 9, cooperatlng with. an upper spring pressed idler roll 10, applies a tearing and feeding pull on the end of the record web. The upper rolls of these two devices are controlled in their position so that when the first two rolls are gripping .and feeding the record web in a direction toward the second set of rolls, the spring pressed upper member of this second set comes down first at one end then clear across the larger lower roll, the speed of the periphery of the lower roll being such .as to pull the paper faster than it is fed along by the first set of rolls. This action tears the paper along the line of perforations or whatever mode is used to form a tearing off line of cleavage at the head of each form. The timing is such that this tearing ofi' action starts to take place just as the weakened line of cleavage in the record web passes through the grip of the first set of rolls.

There is a gear 11 on the feed shaft meshing with a train of

idler gears

12 and 13, which mesh with the gear 14 on the feed roll 9, and a second idler gear 15 connects the gear 14 with the gear 15 on the end of the feed roll 7.

The

upper rolls

8 and 10 have their spindles set into slots 16 in the side frames of the machine so that the rolls may move up and down. There are two spring plunger boxes 17, one at each side of the machine, in which boxes are arranged two vertically moving plungers 18, each plunger having a spring 19. The plungers at their lower ends have grooved shoes 20 to seat over the spindles of the said upper rolls. B this means the two upper rolls are kept by t e spring against the lower or driven rolls of the device.

There are two

cross shafts

21 and 22 below the feed devices. Pinned to the shaft 21 is a plate 23 which forms a cam arm 23, and an operating arm 24. On the other end of the shaft 21 and pinned to it is a plate 25 forming merely a cam arm, the operation from one side being sufficient to operate both cam arms.

The operating arm 24 extends rearwardly to a point where it lies in contact with a cam 32 on the feed shaft of the machine.

On the other of the two cross shafts, viz: the shaft 22, there is a plate 26 having a cam arm 27, and an operating arm 28. This cross shaft at the other side of the machine has fast thereon an arm 29 corresponding to the cam arm 27 without the operating arm.

The operating arm 28 is given a brief movement by means of a roller 30 on the face of the cam 32 on the feed shaft of the machine. The arm 24 has a stud 31 that follows the cam 32 on the feed shaft 3.

The two

cam arms

23 and 25 are arranged to engage the spindle ends of the top roller 10, and the engaging faces of the two arms are not quite the same, the arm 25 as indicated by dotted line in Figure 2 having a slight lag behind the arm 23, at the raised portion of the cam edges thereof. As a result, during the period when the cam 32 on the feed shaft of the machine depresses the operating arm 24, the spindle of the roller 10 will be pressed up away from engagement with the roll 9. When the operatlng arm drops off the edge 32 of the cam 32 this will permit the two

cam arms

23 and 25 to rock into a posi tion permitting the spindle of the roll 10 to fall under its spring pressure into engagement with the large roll 9, with the far end of the roll 10 from the observer in the tv\ 9 1 and 2, engaging the is such that when the point of the operating arm thereof is depressed by the roller on the feed shaft cam, this will rock the cam arms sufliciently to slightly raise the two ends of the upper roll 8, thus freeing the record web from the feed for a momentary interval. The need for this relaxation of grip of the

feed rolls

7 and 8, is in order to permit the record web to feed freely over the pin wheels and align itself with the other Webs being fed. It would only be necessary in a pin wheel feed or other aligning feed manifolder, that the relaxation be over before the rolls 9 and 10 grip and feed the paper.

From the preliminary description of operation it will be evident that since the roll 9 is largerthan the roll 7, with the driving gear ratio the same, the feed between rolls 9 and 10 will be faster than that between

rolls

7 and 8, and thus the paper will be torn off between the two rolls when the line of clevage emerges from the first set of rolls 7 and 8.- The cam on the feed shaft is timed to apply the gripping action of roll 10 when the line of clevage of the record strip for each form has passed through the

rolls

7 and 8, and the suddenness of the grip together with the fact that it applies first at one end and traverses to the other issuificient to tear off the individual form being held between the two rolls neatly and uniformly.

The distance between the two sets of rolls is made short enough that no guides are necessary to make the free edge of the advancing form between

rolls

7 and 8, feed onto rolls 9 and 10, although a guide or guides could be provided.

The modification operates in a similar manner except that the grip of the paper as it comes away from the writing table end is provided by a clamp, which grips the paper.

In the mechanism shown in Figures 3 to 5, there is a guide 29 formed of sheet metal and affixed between the side frames of the machine in such a way as to guide the record web 6 as it is fed from the pin wheels around in a loop where it enters the clamp, and from the clamp to the feed rolls 31? and 30 whence it passes into a suitable storage compartment (not shown).

The clamp is formed of a pair of plates 32 and 33', each having a rearwardly extending

arm

34 and 35 respectively. The arm 35 is pivoted to a shaft 36 extending across the machine to which is pivoted also the arm 34.

The arm 34, however, extends rearwardly to a point when it lies in the path of a stud or roller 37 on the face of a gear 38 on the feed shaft of the machine.

The two plates have mounted upon them the clamp bar, which has a cross bar'portion Inn 39, and two depending legs 40. The legs 40 are slotted and held to the plates 32 and 33 by means of studs 41 on the plates. The plates 32* and 33* are bent under at their lower ends and pierced with holes to receive posts 42 mounted onthe clamp bar so that they will be guided in said holes. Springs 43 around the posts press the clamp bar upwardly, although their normal extension will not press the clamp bar into engagement when the plates 32 and 33 are in their downward position. I

When the roller on the feed shaft gear strikes .down the end of the arm 34 this results in the plates 32 and 33 being thrust upwardly, which presses the clamp bar against the paper, permitting the plates 32 and 33 to rise after the clamp bar has come into compression.

The gear on the feed shaft meshes with an idler 44, which drives a larger gear 45, which is loose on the shaft 36. On the arm 34 of the clamp is mounted a pinion 46 which meshes with the gear 45 in all positions of the clamp bar due to its planetary arrangement.

The feedroll 30 is mounted in the two clamp bars, and has the pinion 46 on its one end to be driven as just noted, by means of the revolution of the feed shaft of the machine.

The pressure roll or idler roll of the feed device for the record web is shown at 31, and is mounted in a slightly loose hole at the side frame nearest the pinion end of the lower feed roll, and has its spindle 50 set in a short slot 49 in the other side frame.

A plate 51 having a hole for engaging over the upper roll spindle is suspended from the spindle at the slotted bearing end, and this plate is pulled down by means of a spring 52, fastened to the plate and the side frame.

As a result of this structure, the upper roll is held at a slight cant away from the observer in Figures 3 and 4, so that as the lower or driven feed, roll is raised by the operation of the clamp arms, the roll engagement will take place and the paper will be gripped first at the one end of the two rolls and then entirely across the rolls as the clamp is pressed home.

Thus, the action in the second modification is the same as in the first, except that themechanism employed is arranged in a different manner.

There will be other .ways of accomplish,

comprising a member to engage 'and hold the paper,- a pair of rolls locatedbeyond said member, and a drive for one'of said rolls, said pair of rollsbeing arranged to exert a pull on the paper in its line of movementand against said first mentioned member, thereby disrupt-' member to engage the paper,,and a member located beyond the engaging means and a drive for the latter member, said latter member being arranged to exert a pull onthe paper, in its line of movement, thereby disrupting the same, said latter member comprising a pair of rolls through which the paper passes, and mechanlsmarranged to bring said rolls .together over the paper at timed intervals, with one end of the rolls contacting before the remainder, so as to imitate the motion of a hand in disrupting thepaper.
