3 Claims. l. 282-21) This invention relates to manifolding or continuous forming stationery of the type-utilized in autographic registers which present the forms successively upon a writing platen and which are effective-for feeding, aligning and delivering the forms.

More particularly, this invention is directed to improvements in manifolding stationery which comprises a plurality of superimposed forms; or in other words, a manifolding pack with the sets of forms separated from each other by means of weakened transverse lines which tion.

The present application constitutes a division of co-pending application Serial No. 379,849, filed February 20, 1941, and entitled Autographic reg ister," which application has now issued into Patent No. 2,326,108, dated August 10, i943. The

register disclosed in the co-pending application is effective for feeding the continuous form stationery of this invention.

- forms are advanced slightly by engagement of a second tread section on the two marginal rolls. Beyond this tread section, all three of the rolls are provided with cut-out sections which free the forms from all feeding pressure so that pins carried on the marginal rolls may engage corresponding apertures in the forms to alignthe forms and complete the feeding operation.

The improved stationery comprises a plurality of continuous strips of forms defined by weaken'ed tear-off lines. Each form includes three' apertures for cooperation with the three sets of rolls. An aperture disposed in the tear-oil line medially of the strip is provided to cooperate with the middle feed rolls. The other two apertures are spaced laterally, one near each side of the form on a line parallel to, and'slightly back from,

'the tear-off line to cooperate with the aligning pins which are carried on the lower marginal It has been an object of the present-inventor I to provide manifolding stationery which is formed so as to permit accurate and positive alignment of the forms during each feeding oper ation and which may be fed through the same register for this purpose regardless of variation in the lengths of the-forms. The improvements particularly lie in the arrangement of the feed ing apertures so as to permit feeding, aligning and dispensing in a'register of the type disclosed in the co-pending application.

In the co-pending application, the inventor has provided an autographic register which utilizes cooperating sets of discs or rolls, upper and lower,

to feed and align the improved forms by virtue of their feeding relationship to apertures in the forms. The rolls ar manually operated by a crank which is fixed to one end of the shaft carrying the lower set of rolls. The upper rolls are in positive transmission connection with the lower rolls by gears, and are carried on acommon shaft which is spring-urged to provide a peripheral contact between the two sets.

The feeding-mechanism incorporates three sets of rolls. Two of thes engage the formsmarginally. The lower rolls of these sets are provided with cutaway or strip releasing spaces for I freeing the strips from their contacting pressure feed rolls. The side apertures may be spaced any desired distance from the side edges; that is, they need not be as near the sides as shown.

The superimposed strips are fed through the rolls in three stages; one, a major feeding operation, in which all three sets of rolls advance the strips; two, an adjusting feeding operation in which the compensating rolls are employed to feed the strips; and three, a minor feeding opera,- tion wherein the strips are absolutely aligned and the forms dispensed.

In the first stage, th strips are always advanced a distance slightly less than the shortest form to be used. In this stage all three of the lower feed rolls engage the strips.

f In the second stage, cutaway or strip releasing sections in the peripheries of the two marginal feed rolls free the forms so that only the compensating feed roll is effective. The compensating feed rolls advance the forms until the middle apertures in the superimposed forms are' all aligned between the two compensating rolls; At this point, the feeding contact of thecompensating rolls is broken since the rolls contact each other through the apertures. Thus, it may be seen that within practical limits, any length of form may be employed. In the third stage, first, the forms are engaged by a short tread section on the marginal feed rolls and advanced slightly, Secondly, the forms are freed from the contacting pressure of all three sets of rolls by the cutout sections in the peripheries of all three rolls and the pins carried by the marginal rolls engage .2 from a description of the accompanying drawn s,inwh1ch:

In order to make it-more convenient to read the drawings and specifications in the respective applications, that is, the co-pending application and the present application, the parts are correspondingly numbered.

The strips of forms utilized here consist of lengths of paper having forms ll defined by weakened cross lines i2. An aperture 13 is provided centrally for each form midway on a scored or perforated line i2, for cooperation with the compensating rolls. Just back of the line if in each case are apertures I, one at each sid of the strip for cooperation with the feed rolls.

The lower rolls are substantiall larger than 'the upper rolls and include a pair of feeding rolls "-3! and an adjusting or compensating feed roll 35. The shafts upon which the upper and lower rolls are carried are in'positive transmission connection through meshing pinions (not shown). The feedingor translating rolls areoperated by means of a crank handle 23 pinned to one end of a shaft 24 which carries the lower rolls. Each roll 34 carries a pin 38 extending radially slightly beyond the line of the periphery of the roll. The pins may be made integrally with the feed rolls, as shown, and are positioned on the inside of the roll in each case. The compensating feed roll 35 is mounted on the shaft 24 medially, between the two feed rolls.

The lower roll 35 has a single short cutaway or pressure relieving section 38 in its periphery. This portion 39 comes into effect only at the very end of the rotation. each have two cutaway sections. One, indicated at an in each instance, corresponds to the cutaway section 38 in the lower compensating roll. These pressure relieving sections 39 and 49 come The lower feed rolls 34 into effect to free the forms so that the pins 3B 38 carried with the feed rolls can make the final advance of the forms. The second cutaway section on the lower feed rolls, indicated at ii in each instance, extends over slightly less than half of the periphery of the lower feed rolls. These cutaway sections 41- are provided to release the feeding pressure on the forms so that the compensating rolls can bring the forms into registry. A short tread section 42 is provided between the two cutaway sections on each lower feed roll to start the final feed operation just before the pins 38-38 come into operation.

Operation In Figures 4 and 5, the compensating rolls 21, 35 and one set of the feed rolls 26, 34 respectively are shown near the start of a rotation. It will be noted that both are effective for advancing the forms. When the form are advanced to a point where the middle aperture it, which is ahead of the marginal apertures 14, comes between the compensating rolls, the start of the cutaway sections 4l-4l on the feed rolls is adjacent the upper rolls. Therefore, the pressure of the feed rolls is released from the forms and only the compensating roll is effective. When all of the middle apertures in the superimposed forms are in registry, the upper and lower compensating rolls will contact each other through the apertures i3, and, as shown in Figure 6 of the drawings, theforms will be out of feeding contact with the rolls. This compensating roll also serves as a pre-aligner in that if one or more of the forms is lagging, the first form to reach the compensating rolls will stop when its middle aperture advances out of feeding contact with the compensating rolls and the rolls will, therefore, contact the lagging forms and advance them until all of the apertures register and the compensating rolls contact each other through them.

The rotation of the rolls after the compensatin interval continues without feeding the forms until the tread sections 42-42 on the lower feed rolls come around to contact the forms. This stageis shown in Figure 9 of the drawings. The short tread sections 4242 advance the forms slightly to bring the marginal apertures 4-H forward to a position wherein the pins 38-38 enter them. As soon as the forms reach the. point wherein the pins are established in the marginal apertures, the cut-out sections 39 and fill-50 in the peripheries of all three lower rollscome into effect to release all pressure on the forms. Therefore, the final advance is made by the pins to bring the forms into absolute registry.
