character which in addition will align thevarious webs through engagement with registering holes therein of pins or the like, 1

said webs being in a loose relation at .the time of alignment.

While the embodiment selected for purposes of illustration shows feed pins forming a part of the feeding operation of the paper, it will be understood that some merely reciprooatory or slightly movable element, without feeding function, suitably synchronized with the adjustable feed, would satisfy our object in its broad and general aspects.

We abcomplish our objects by that cer-- tain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 is a side elevation of an autographic register embodying our invention.

Fi re 2 is a detail elevation of the adj usta le feeding elements.

Figure 3 is an end elevation thereof.

Figure 4 is a perspective view of one of the feedv members.

Figure 5 is a like view of another'one of them, this one not carrying the feed pin element, as does the one in Figure 4.

The machine selected from the point of view of its simplicity for illustrating our inventioh in manifolding apparatus is an autographic register, having a casing 1, within which are spindles 2, 2, for rolls of paper 3, and which embodies a writing ,table 4, over which the paper passes and on which it receives impressions.

Mounted within a housing 5, located at the top of the machine beyond the writing table is a roll 6 or the like which is under the influence of springs 7, pressing downon the attenuated ends thereof, said ends being so mounted as to slide in the said housing. As will be observed below, this resilience of the roll 6 need not be arranged for, as its position will be constant for all operations,

since the roll is really more of a rotary abutment.

A feed shaft 9 is provided having suitable bearings in the casing, and under control of an operating device such as the handle 10. The writing table may be extended out between the roller 6 and the feed shaft to serve as a stripper, or some separate stripper or stripping fingers may be provided. In the former case, the said table will be cut away at 11, to clear the feeding device, which will now be described, and permit it to engage the paper on the lower side while the roller 6 engages it on the upper side.

It is the essential characteristic of the feeding device that it present a feeding periphery to the paper, which is adjustable in dimension, whereby the paper will be fed for a distance corres onding to the extent of said feeding perip ery.

Thus we provide in the instance illustrated, a pair of disks 12 and a pair of disks 13, one of one pair being used in conjunction with one of the other pair to provide two feeding elements, the numbers not bein essential.

ach disk has a hub 14, mounted over, the feed shaft, and held in adjusted position thereon by means such as a set screw 15.

The disk 12 has a peripheral extension 16, which is less than a complete circle, and the balance of the periphery is formed on a smaller radius than the said extension, although the exact construction of this balance is non-essential.

Located in this instance just ahead of the beginning of the peripheral extension 16, on the disks 12, are feed and alignment pins 17, which are of a nature to enter readily and easily into holes (not shown) which will be formed in the webs of paper being fed. These holes we prefer to have located at the heads of the forms, and to be of a size considerably larger than the pins, the essential feature of them in this machine being, however, that they be positioned similarly for each form on each web.

The disks 13 are mounted preferably closely alongside of the disks 12, and have extended peripheries 18, which also are less than a complete circle.

On the ends of the feed shaft, we prefer to have disks 19 of uniform diameter, which bear on the ends of the roller 6, thereby maintaining it away from contact with the writing table should it be extended between the feeding devices, and for maintaining it away from contact with the non-extended portions of the feed disks. Thus while the roll is acting as an idler member of the feed, it will not act to clamp the paper on the writing table, in such a way as to hold it frictionally. Neither will it interfere with the adjusted length of feed.

We will normally provide a releasable stop 20 for the feed handle, and will locate the disks 12, alike to each other, and with the pins thereon at the desired position relative to the stopped position of the feed handle. As shown, this may well be such as to bring the pins through the upper portion of their movement at the time that the handle is stopped, so that the pins will accomplish their feeding and aligning at the close of each operation and the beginning of each operation.

As so constructed, the operation of the device is as follows The operator will first position his disks 12, permitting their extended peripheries to pass up through the openings in the stripper or writing table. He will then locate the disks 13 in such a way that their extended peripheries will partially lap those of the disks 12, and in addition to them complete such part of a complete circle, as is desired.

He will then arrange the-paper so that the holes thereon seat over the feed pins, and position his feed handle in stopped position. Upon release and operation of the feed handle through each complete circle, the machine will then feed paper so long as contact is maintained between the disk peripheries and the upper roll- 6, but as soon as the eripheries end and no longer contact with t e upper roll, the feeding motion will stop entirely, until the pins come around again. The eripheries will be arranged so that they eed the paper just the right amount to bring the alignment apertures to a position to be engaged by the pins after each 0 ration, the adjustment being made by t e operator for this purpose. The pins will t en pick up the paper, and draw it through a short path, thereby aligning the printing on the paper, by bringing into absolute registry the holes formed therein.

The feeding peripheries in all feeding operations are so arranged as to clamp the paper betweenthem and the roll 6, and the resilienceof this roll is not required whereits position against the disks 19 can otherwise be secured;

We do not desire because of a failure to point out modifications of our device to thereby exclude from the interpretation of the claims that follow such mechanical equivalents of the parts claimed as would occur to those skilled in the art involved.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
