This invention relates to improvements in manifolding stationery. adapted to cooperate with strip-feeding and margin-severing devices, this application being a division of my copending application Serial No. 405.846, filed August 7, 1941.

More particularly, the present invention relates to manifolding stationery having marginal perforations cooperating with movable series of feeding pins to advance the strips while maintaining them in alignment with each other and with the writing line of a writing device, and further being adapted to cooperate with means for automatically severing a binding and feeding margin from the body7 portions of the stripsv concurrently with and incident to said feeding operation.

Manli'olding stationery, especially for use in typewriters, generally comprises a plurality of i superposed continuous strips (usually printed) interleaved with transfer strips, and divided into successive form lengths by transverse weakened severing lines at form-length intervals.

` lFor positive feeding of the record strips, a series of perforations are usually provided adjacent one or both margins foi` engagement with pin feed devices provided on the writing device, for instance, on the platen of'a typewriter.

Depending upon the number and nature of the strips, it is sometimes possible to maintain adequate alignment of the strips by means of a single row of perforatlons adjacent one margin, which engage a corresponding pin feed device on the platenl of the typewriter. However, for many types of stationery, the control and support thus provided isinsufiiclent to maintain the desired alignment of the strips on the platen.

The use of a set of' apertures in both lateral margins of the stationery, engaging corresponding dual pin feed devices, is generally more reliable, but requires the use of a platen having a pair of feed-pin members which are spaced apart by a distance determined by the .width of the stationery. If stationery of various widths is to be used, the platen must be replaced, or the spacing of the pin feed members must be altered to accord with the width of the stationery.

It is an object of the present invention to provide continuous multiple strip manifolding lstationery having a series of Din feed apertures for cooperation with pin feed devices which reliably maintain the strips in accurate registry with the writing line of a Writing device, but so arranged that stationery of different widths requires no lalteration in the feeding mechanism, and so that one margin is available for inscription.

To accomplish this, the present invention provides the manifolding stationery with at least two transversely spaced series of feeding apertures adjacent a longitudinal margin of the strips. preferably at the left-hand side wherein the individual apertures of one series are preferably, aligned, transversely of the strips, with apertures of the other series, and provides a pin feed device with parallel series of pins to engage said apertures. By thus engaging the spaced rows of pins, even though they be at the same side of the platen, the pile of strips being fed is securely held against skewing relative to the platen.

It has been found that stationery which would i'ail to maintain its alignment if only one'set oi feeding pins and apertures were used, is satisfactorily aligned by a double set of parallel feed pins and apertures adjacent one of its margins, especially when the apertures and pins are transversely aligned. Since both sets of pins are at the same end of the platen and the 'use of pins at the .other end of the platen is dispensed with, stationery of any width within the limits c1' the machine may be used-without the necessity oi.' altering the machine.

In order to retain the superposed forms and transfer sheets of continuous manifolding stas tionery against relative mutual shifting during advancement by a feeding device to an inscrip. tion position or writing line, the strips and trans fer sheets may be fastened together. for instance by staples or adhesive binding along e. margin of the strip, and/cr by staples at intervals in the body of the strip. To permit separation ofthe multiple copies after inscription, the bound or stapled margin was formerly removed by hand from the inscribed portion of the strips.

When the superposed manifolding strips, provided with multiple sets of pin feed apertures according to this invention, are bound together at the margin. one set of feed holes is preferably formed in the bound margin and the other set in the body of vthe strips.

Various means have been proposed heretofore to sever the bound margins of the inscription-rcu ceiving portion of manifolding strips, For instance, it has been proposed to use rotary knives or pressure devices which sever or rupturev the strip margin incident to the feeding operation.

According to the present invention, the pin feed device is not only adapted to perform the function of positively feeding the strips and maintaining their alignment, but also to sever the bound margin of the strips, incident to itsoperation.

This is accomplished by so arrangingthe pin feed device that as the two series of pins advance or rot te with the platen and progressively engage the series or apertures in the severable bound margin and body of the manifolding sta--v tionery, the pins of one set move outward along the platen, diverging from the other set of pins, and apply sumclent lateral tension to the bound margin of the strip to sever it along the weak ened severing line from the main portion of the strips.

After the pins have rotated beyond the writing line, the inscribed forms and the severed margin are stripped from the pins for delivery, and the divergently movable severing. pins then move back automatically to their initial position where they are adapted to reengage the incoming strips on the receiving side of the platen.

During the severing operation, the strips are subjected to tension solely in transverse direction, whereby the application of any force tending to disalign the body of the stationery at the writing line is avoided.

Since the series of divergent pins and the series of ilxed pins are disposed at the same end of a platen advantage may be taken of the other feature of this invention, and no adjustment is necessary to accommodate strips of various widths, accommodated by the length of the platen.

After a form. length of stationery issues from the machine and is severed from the strips, its bound margin having been removed in the aforesaid manner, one or more copies thereof may be reinserted in the machine for typing additional data thereon, reengaging the holes with the traveling series of transversely fixed pins, whereby accurate reregistration andrealignment of the form with the writing line of the machine is insured.

Other features and advantages of the invention will appear from the following description, referring to the accompanying drawing, in which:

Fig. lis a transverse cross-section substantiallyl along the line 4- of Fig. 3.

As illustrated in Fig. l of the drawing, the stationery, according to the present invention, comprises a plurality of superposed continuous record strips 20 containing printed matter and lines on each form length. Continuous transfer strips 22 are interleaved with the superposed record strips so that the inscriptions on the topmost strip will be reproduced on each of the underlying strips.

Preferably, the strips 20 are divided into form lengths by transverse weakening lines 24 to facilitate separation of the form lengths after inscription. y

According to the present invention, a marginal series of apertures 30 adapted to cooperate with the pin feed device is provided adiacent a lateral margin, preferably the left-hand margin 2-8, of the stationery and a similar series of apertures 3l is provided adjacent the same margin, but spaced inwardly on the strip from the apertures at. apertures 8@ and Si are preferably arranged in parallel rows. with the aperture in the two rows in mutual transverse alienmen Engagement of the two series or apertures with a pair of corresponding pin feed devices on a writing machine maintains the superposed strips accurately aligned with the writing line of. the machine, and serves to hold the superposed form lengths in mutual registration. The same pin feed device may be used with strips of varying width without any adjustment or alteration and the margin of the strips opposite the apertured margin is available for inscription.

To prevent relative shifting of the superposed form lengths, the manifolding strips, according to the present invention, are bound together along the margin fia, as for example, by means of staples 2i at longitudinally spaced intervals. Preferably, at least one staple is provided in each form length. A weakening line of perforations it is provided in each of the superposed strips tween the parallel series of apertures tit and After inscription of each form length, the

marginal portion it, bearing staples 2l, is severable from the body of strips to permit separation of the superposed copies. By forming the said severing line between the two series of apertures 30 and 3i, apertures at are removed from the inscribed portion of the form length when the marginal portion 2b thereof is severed. lf itis desired to replace one or more copies of the form length in the Writing machine for inscription of additional data thereon, the remaining series of apertures t! may be reengaged with the corresponding pin feed device, whereby the dellneations and written matter are accurately realigned in their original relation with the writing line of the machine.

The transfer strips 22 inthe manifolding stationery of Fig; l are provided with transverse weakening lines 25 which are in registration with the severing lines 213 of the record strips for the major portion of their length, but preferably offset from 4the severing lines 2d adjacent the center of the strips. As a result. upon severing the written form lengths from the superposed manifolding strips, each of the transfer sheets is left with a tab 2l protruding beyond the transverse severed edge of the record strips all, while atthe same time, a notch is formed in the bottom of each adjacent carbon sheet. The con- 5 struction illustrated is described in the patent to Conklin No. 2,083,295, issued June 8, 1937.

After removal of the stapled marginal portion 28, the tabs 2l may be grasped with the thumb and forenger of one hand, while the record sheets are heldbetween the thumb and forenger at the opposite margin over the notches in the carbon sheets, and the latter may be pulled out as a whole from between the form length record copies.

Moreover, to aid in maintaining the superposed record and transfer sheets of each form length in mutual registration, the superposed strips are preferably secured together by means of staples 29, preferably at the center of the tabs 2l in the carbon sheets, and coincident with the transverse weakening lines 24 of the record strips. Upon severing the superposed strips transversely along the weakened lines 24 and 26, the staple 29 is released from the record strips 20 but still holds the tabs 21 of the transfer strips together,

facilitating removal of al1 of the transfer strips at the saine time.

The transfer strips 22 may extend laterally to the outer margin of the record strips, if desired, so that they are retained in place by the marginal staples 2|. If the strips have staples 28 in the center, as shown. theseV will also serve to retain the transfer sheets against shitting. and the carbon sheets may terminate short of the extreme margin of the record strips, for instance, at the weakened severing line 23.

A feeding device with which manifolding stationery of Fig. 1 is adapted to be used, according to the present invention, is illustrated in Figs.

v2 to 4 inclusive, and is shown mounted on the left-hand end of a vconventional typewriter platen. The latter comprises a shaft 32 journaled in a stationary bearing plate 34, and carrying a terminal knob 33 for manual rotation thereof, and a platen roll 3l secured thereto by a set screw 38. 4 i

The end of the platen roll 35 is reduced to receive a pin ring 31, the outer surface of which is preferably cylindrical and of the same diameter as the platen roll 3l. Adjacent its inner end, ring 31 carries a circumferential annular series of radially projecting feed pins 38.

In order to secure the ring 31 to the platen,

strips in accurate alignment at the writing line of the machine.

As indicated in Fig. 2, cam groove 48 con tinues parallel to the annular series of pins 38 so as to hold the pins 44 inward at the inner end of the slots 4|, substantially until the said pins attain thev writing line 48 at the front of the platen.` At this point or just beyond, cam groove 48 diverges from the end of the platen.v Consequently, as the stationery travels beyond this point, pins 44 move outwardly from pins 38, applying sufficient tensionto the strips at the severing line 23 to tear of! the bound margin strip 28 containing apertures and staplesA 2|.

The severed margin strips, as well as the record strips leave the vfeed pins at the top of the platen inthe usual manner, any conventional guide or stripper means such as that indicated at 38 being used for this purpose. Beyond this point, cam groove 48 converges inward toward the platen resuming its initial position, parallel to the annular series of pins 38 in advance of the point where the pins first engage lthe incoming strips of stationery. As a result, pins 44 are progressively returned to their inward positions in slots 4|, whereby they are again adapted, with pins 38, to engage the apertures 38 and 3| in the one or more lugs 38 may be provided thereon whichproject inwardly from thev ring to engage a corresponding socket 48 in the platen., As shown in Fig. 3, the said projections may be Adjacent its outer end, the ring `3l is provided with an annular series of axially elongated slots 4| which are preferably axially aligned, as illustrated, with the pins 38. The reduced portion of the platen roll is provided with a series of grooves 42 extending axially inward from the end of the roll beneath each of the slots 4|.

Each of the grooves 42 is adapted to receive a slide plate 43 carrying a pin 44 which extends through the slot 4| in ring 31. The slide plates 43 are adapted to slide to and fro in axial direction in grooves 42 to move pins 44 back and forth inthe slots 4| v The inner ends of the slots 4| are so spaced from pins 38 that when pins 44 are disposed at the inner ends of said slots, the two sets ofpins slots 4| at predetermined points in their travel incident to the rotation of the platen 35. This means comprises a stationary cam plate 45 secured to the bearing plate 34 adjacent the end of the platen roll, said cam plate having a peripheralcam groove 48 for engaging tabs 41 on the outer ends of the slide plates 43.

The manifolding strip is fed to the platen `formed integral with one or more of the pins 38.

from the rear, passing around the platen from i the bottom to the top. At the point where apertures iii of the stationery first engage pins 38, the cam groove 48 is parallel to a plane perpendicular to the axis of the Vplatten and consequently to the annular series of pins 38, and holds pins 44 inward so that they register with apertures 30 in the separable bound margin strip 28 of the stationery. The engagement of the two sets of pins with the parallel series of apertures insures positive advancement of the strips and holds the superposed record strips and transfer A'without any change in incoming stationery on the receiving sideof the platen. During the severing operation, pins 38 retain the inscribed portion ofthe strips in accurate alignment by continued engagement with the perforations 3| until the st ps leave the platen on. its delivery side.

As the inscribed forms issue from the machine, they may be severed at will along transverse severing lines 24 and 25. The transfer sheets 22 are removed as a unit from the record sheets 2|| by grasping the tabs 2'l/at`one end of the form' length and the record sheets at the correspondingnotch at the opposite margin, and pulling the two apart. The transfer sheets, which are held together by the central staples 28 are snapped out as a unit. leaving the inscribed forms ready for distribution.

As stated above, certain of the inscribed record sheets may be reinserted into the machine in such a manner that apertures 3| reengage pinsl 38.

Additional data may then be inscribed on the forms, the said pins insuring proper realignment of the printed forms with the writing line of the machine.

By virtue of the fact that both sets of pins are disposed at the same end of the platen, the stationery may be made of any desired width which can be accommodated by the length of the platen the feeding and severing mechanism.

Variations and ymodications may be made within the scope of this invention and portions of the improvements may be used without others.
