. DAYTON, OHIO MANIEQLDINGHMAGHINE Application filed July 22, 1929. -Seria1 No. 380,170. a,

My invention has to do with providing an improvement in that type of manifolding register in which the manifolding forms are fed by a rotating disk in connection with a pressure member, and in which the alignment and registry of the forms is corrected at each revolution of the machine by a pin device. This type of register is to be distinguished from that in which the paper is fed by the continuous action of pin wheels.

The method of feeding paper by the expedient of clamping it between the periphery of a disk, and a pressure member is not new. One form of such a register is shown and described inthe Patent #1,445,108 to John Q. Sherman. This patent also sets forth a pin aligning device. In registers of this type, in order that the pin aligning and registry mechanism may become eifective it is necessary that the clamping of the paper between the disk and the pressure member be released during the active operation of the pin device. the patent referred to by providing the disk with a cam which would raise the pressure member from the periphery of the disk at a certain desired point in its travel.

It is an object of my invention to provide an improved mechanism not only for feeding and aligning the paper but for releasing it at the time when the aligning means is to become operative.

It is a further object of my invention to provide a mechanism which will be smoother and more accurate in operation.

It is still another object of my invention to provide a construction which will be cheaper to manufacture and less liable to get out of adjustment.

These and other objects of my invention which I shall point out hereinafter or which will be apparent to one skilled in the art upon reading these specifications, I accomplish by that certain construction and ar rangement of parts of which I shall now two.

This was accomplished in' describe a preferred embodiment, reference being made to the drawings which accompany this specification.

In these drawings:

It has been usual in manifolding registers employing the paper feeding and aligning principle outlined above, to provide a cam mechanism for elevating the pressure memher or clamp when desired. Such a structure involves a lack of smoothness in operation and a tendency to irregularity particularly because at the point where the cam becomes operative, the resistance to the operation of the feeding handle is suddenly and considerably increased. In my invention, I provide for smoothness and ease of operation by cutting away the feeding disks over an area representing the place in the movement of- "the feeding mechanismv at which it is desired to release the paper, and I provide stops or abutments upon the writing table to hold the 7 pressure member or clamp away from it eral shafts and the like may be mounted. A

. feed shaft 23 extends transversely of the frame and is equipped with a handle 24 by which it may be rotated. A suitable stop mechanism indicated generally at 25 is designedto limit the movement of this handle toone complete operation for one release thereof. This device may be of any suitable character and does not form a part of my invention. Upon the shaft I rigidly mount disks 8 which are intended to clamp and feed the paper against a pressure member presently to be described. The disks carry pins 10 which are adapted to engage the paper for alignment and registry when released by the cam cut 9, as will hereinafter be explained. The machine will be understood as equipped with a writing table 26 which is a metallic plate mounted upon bars .27 which are hinged'to a shaft 2-8 lying transversely of vthe frame. The writing table is curved in its rear portion to form an apron 29 which apron is adapted to rest upon a shaft 7. M

Thus the writing table is supported within the cabinet upon the shafts 7. and 28, so that it lies above the feeding rolls 8. The writing table has two pairs of slots, 2 and 3, the first pair being for the clearance of the paper feeding disks 8 and the second pair for the clearance of the aligning pins 10. Abutments 4 are formed on the table preferably by upsetting ears as shown, and these abutments are adapted tolie beneath the clamping .element when it is in position, and to prevent the descent of it into clamping relationship with the central portion of the table.

ldy machine is'adapted for use either with rolls op flat packs. In the embodiment shown i have illustrated a flat pack 30' con-' sisting of three forms which pass together around idler 31 and severally around idlers 32, '33 and 34, thence passing over the writing table 26, over the feeding disks 8 and beneath the pressure member. Two of the forms shown issuing from thehmachine at 35; the third form is shown being fed down into the machine again at 36 and being collected into a record pack 3? in a separate compartment. To assist in the feeding of the paper into the record cabinet, a hinged deflector plate 38 18 shown in Figure 1.

It will now be clear that the feedin disksplate indicated in the several figures at. 39

which is bent preferably so as to present a central depression, and lengthwise ribs. This bending is usefulin stiffening the plate. The rear edge 40 ofthe plate is sharpened so as to form a tear-off knife and the plate itself is mounted by screws 41 upon arms-42' which are hingedly mounted upon a shaft 7, so that the entire clamping assembly may beraised and lowered upon this shaft. A spring 6 operating against an abutment 43 tends to keep the pressure element against the disks. On there ar end of the arms 42 there is formed a shoulder 44 which is adapted, when the pressure member is raised,

be released againby rocking the lever 46 of the cam 11 forwardly.

Slots 47 are made in the plate 39 for the clearance ofthe pins 10, and the plate is further provided with earsin which small rollers 1 and 5 are revolvably mounted upon small shafts. This construction will be readily understood from an examination of the several figures. The rollers 1, when the pressure element is depressed are adapted to contact the peripheries of the disks 8 as shown in Figure 5, and when paper is being fed through the machine, to clamp this paper tightly against the disks. The sur-- faces of the disks 8 and the rollers 1 may both be roughened, scored or knurled to increase the grip upon the paper, and the manner of feeding the paper by the rotation of the disks will now be quite clear.

The pins 10 are mounted upon the hubs of the disks 8 so as to be in positive position with relation thereto, and the peripheries of the disks 8 are cut away for a short distance as shown at 9 in Figure 4. The purpose of this cut away portion is to release the paper so that the pins 10 may pull or jog it into alignment and registry and the circumference of the disks'8, less the length of the depressed portions 9, are made of sufi'icient length to feed the paper practically the one form length. The pins 10 are adapted to engage the paper when or shortly after it is released and to feed it a slight distance dur ing the alignment, thereby completing the feed. The paper will of course, have holes made in it in proper registry with the printed forms thereon,'and at the head of each,

for the engagement of the pins 10; and this type of register is advantageous both in that it does not require paper with continuous marginal perforations and also in that the forms, each with two perforations corresponding to the pins 10, are ready for binding in a, two post hinder or other binding or filing device, without any further treatment. In order that the pressure rollers 1 will not follow down into the depression 9 in the disks, but will properly release the paper over these depressions, means must be taken to limit-the descent of the plate 39. I These means comprise the ears 4 upon the writing table and the small rolls 5 upon the pressure element which are adapted to come into contact with each other when the pressure element is released. The abutments 4 and the rolls 5 are adjusted so as to maintain a fixed and safe clearance between the pressureelement and the table top. Figure 4 shows the position of the feeding devices at the beginning or end of ajfeeding revolution. It will be observed that the depression 9 has passed by the rollers 1 and that these rollers are now in contact with the periphery of the disk 8. It will also be observed that the pins 10 are in substantial alignment with the pressure element and that they, ofcourse, extend'thro'ugh the holes'in the paper. At this point, the paper is tightly clamped between the disks and the rollers and, if. it is the end of a stroke, the issued paper webs 35 will be firmly held and may be torn'off against the knife 40. After the entry of another transaction upon the next form, the device 25 will be released and the handlerotated one full turn in a counter clockwise directionf The paper tightly engaged between the rollers 1 and the peripheries of the disks 8 will be fed through almost one form length, 'until the, depressions 9 arrive beneath the rollers 1. At this point the paper will be released, the pressure element, no longer held up by the action of the disks upon the rollers 1, will descend until the rollers 5 contact the abutments' i. There will be suflicient clearness so that the paper is not clamped between the table and the pressure element. With the further revolution of the handle, the pins 10' enter the holes in the next succeeding form, and during a slight movement of the handle, will not only jog or pull the paper into alignment and registry, but will feed it forward, to some extent, completing the feed. When the handle has returned to the starting position illustrated in Figure 4: thedepressions 9 will have passed completely under the pressure rollers I, and these rollers will again be clamping the paper against the peripheries of the disks 8. The paper will be clamped both for tearing ofi against the knife 40 and for the entry of new, data upon the next form. i
