18 Claims.

The invention relates to improvements in feeding devices for manifolding stationery, and also to improved manifolding stationery for use with such devices.

More particularly, the present invention provides a positive feed device for manifolding stationery having pins adapted to cooperate with marginal perforations in superposed manifold strips for feeding the strips while maintaining said strips in alignment with each other, and with the writing line of a writing device, and further, means for automatically severing a binding and feeding margin of the strips from the body portions thereof concurrently with and incident to the feeding operation.

Th present invention also provides continuous form manifolding stationery having improved registering and aligning apertures therein for cooperation with pin feeding devices, and also adapted to cooperate with the aforesaid margin severing device of the invention.

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

For positive feeding of the record strips, a series of perforations are usually provided adjacent one or both margins for 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 perforations, adjacent one margin, which engage a corresponding pin feed device on the platen of the typewriter. However, for many types of stationery, the control and support thus provided is insuificient 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 predetermined distance. 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 stationery having a series of pin 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 alteration in the feeding mechanism, and one margin may be made available for inscription.

To accomplish this, the present invention provides the manifoldi-ng stationery with at least two transversely spaced series of feeding apertures adjacent a longitudinal margin of the strips preferably at the left-hand side, and provides a pin feed device with the 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 fail to maintain its alignment if only one set of feeding pins and apertures were used, is satisfactorily aligned by a double set of parallel feed pins and apertures adjacent one of its margins. 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 of the machine may be used without the necessity of altering the machine.

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

When the superposed manifolding strips, provided with multiple sets of pin feed apertures accordin 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 the strips.

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

It is a further object of the present invention to provide a pin feed device which not only performs the function of positively feeding the strips and maintaining their alignment, but also of severing the bound margin of the strips, incident to its operation.

This is accomplished by so arranging the pin feed device that as the two series of pins rotate with the platen and progressively engage the series of apertures in the severable bound margin and body of the manifolding stationery, the pins of one set move outward along the platen, diverging from the other set of pins, and apply sufiicient lateral tension to the bound margin of the strip to sever it along the weakened 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 in the usual manner. 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. As there are no blades to become dull, the device requires substantially no maintenance.

In the broader aspects of this feature of the invention, the set of pins may be located at opposite ends of the platen. But when the series of divergent pins and the series of fixed pins are disposed at the same end of a platen, advantage may be taken of the other feature of this invention, and no adjustment will be necessary to accommodate strips of various widths accommodated by the length of the platen.

' Aftera form length of stationery issues from the machine and is severed from the strips, its bound margin having been removed in the aforesaidmanner, 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 accuratev reregistration and realignment of the form with the writing line of the machine is insured.

Other features and advantages of the inven-' tion will appear from the following description, referring to the accompanying drawings, in which:

. scribed portion of the form length when the marginal portion thereof is severed. If it is desired Fig. 10 is a perspective view of the device of the present invention applied for feeding and severing the manifolding stationery of Fig. 9.

As illustrated in Fig. 1 of the drawings, 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.

According to the present invention, a marginal series of apertures 30 adapted to cooperate with the pin feed device is provided adjacent a lateral margin, preferably the left-hand margin 28 of the stationery, and a similar series of apertures 3| is provided adjacent the same margin, but spaced inwardly on the strip from the apertures 30. Apertures 30 and 3| are preferably arranged in parallel rows, with the apertures inthe two rows in mutual transverse alignment. When the stationery is used with a pair of pin fed devices of which only one or two pins are fully engaged with the stationery at a time as in the case of a rotary platen having disappearing pins, trans: verse alignment of the holes of the two series insures simultaneous full engagement of a hole in both series with pins of the feeding device, whereby positive alignment is insured.

Engagement of the two series of apertures with a pair of corresponding pin feed devices on awriting 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. I

To prevent relative shifting of the superposed form lengths, the .manifolding strips, according to the present invention, are bound together along the margin 28, forexa'mple, by means of staples 2! at longitudinally spaced intervals. Preferably, at least one staple i provided in each form length. A weakening line of perforations 23 is provided in each of the superposed strilpslbetween the parallel series of apertures 30 an 3 After inscription of each form length, the marginal portion, bearing staples 2|, is severed from the body of strips to permit separation of the superposed copies. ering line between the two series of apertures 30 and 3|, apertures 30 are'removedfrom the into replace one or more copies of the form length in the writing machine for inscription of additional data thereon, the remaining series of apertures 3| may be reengaged with the corresponding pin feed device, whereby the delineations Fig. 1 are provided with transverse weakening lines 25 which are in registration with the sev- By forming the said sev ering lines 24 of the record strips for the major portion of their length, but preferably offset from the severing lines 24 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 21 protruding beyond the transverse severed edge of the record strips 20, while at the same time, a notch is formed in the bottom of each adjacent carbon sheet.

After removal of the stapled portion at the margin 28, the tabs 21 may be grasped with the thumb and forefinger of one hand, While the record sheets are held between the thumb and forefinger 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 21 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 25, the staple 29 is released from the record strips but still holds the tabs 21 of the transfer strips together, facilitating removal of all of the transfer strips at the same 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|.

The feeding and margin severing device, according to the present invention, with which manifolding stationery of Fi 1 is adapted to be used, is illustrated in Figs. 2 to 8 inclusive, and is shown mounted on the left-hand end of a conventional 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 35 secured thereto by a set screw 36.

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

In order to secure the ring 3'! to the platen, one or more lugs 32 may be provided thereon which project inwardly from the ring to engage a corresponding socket 49 in the platen. As shown in Fig. 3, the said projections may be formed integral with one or more of the pins 38. Adjacent its outer end, the ring 3'! 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 011 35 is provided with a series of grooves 42 extending axially inward 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 .4 which extends through the slot 4 in ring 37. The slide plates ii! are adapted to slide to and fro in axial direction in grooves to move pins 45 back and forth in the slots 4!.

The inner ends of the slots &5 are so spaced from pins 38 that when pins 44 are disposed at the inner ends of said slots, the two sets of pins 44 and 38 are adapted to register respectively with apertures 33 and 31 in the manifolding stationery of Fig. 1.

Means is provided, according to the present invention, to control movement of the pins 44in the 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 pcripheral cam groove 46 for engaging tabs 41 on the outer ends of the slide plates 43.

The manifolding strip is fed to the platen from the rear, passing around the platen from the bottom to the top. At the point where apertures 3| of the stationery first engage pins 38, the cam groove 46 is parallel to a plane perpendicular to the axis of the platen and consequently to the annular series of pins 38, and holds pins 44inward so that they register with apertures 30 'in the separable bound margin strip of the 'st'atiom cry. 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 strips in accurate alignment at the writing line of the machine.

As indicated in Fig. 2, cam groove 46 continues parallel to the annular series of pins 38 so as to hold the pins 44 inward at the inner end of slots ii, substantially until the said pins attain the writing line 48 at the front of the platen. At this point, or just beyond, cam groove 46 diverges from the end of the platen. Consequently, as the stationery travels beyond this point, pins 44 move outwardly from pins 38, applying suflicient ten" sion to the strips at the severing line 23 to tear off the bound margin strip containing apertures 30 and staples 2|.

The severed margin strips, as well as the record strips leave the feed pins at the top of the platen in the usual manner, any conventional guide or stripper means, such as member 50 being used forthis purpose. Beyond this point, cam groove 46 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 the incoming strips of stationery.

As a result, pins 44 are progressively returnedto their inward positions in slots 4!, whereby they are again adapted with pins 38 to engage the apertures 30 and 3! in the incoming stationery on the receiving side of the platen. During the severing operation, pins 38 retain the inscribed portion of the strips in accurate alignment by continued engagement with the perforations 3! until the strips 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 20 by grasping the tabs 2'! at one end of the form length and the record sheets at the corresponding notch at the opposite margin, and pulling a manner that apertures 3! reengage pins 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 sta tionery may be made of any desired width which interleaved transfer strips 22a, transverse severing lines 24a and 25a at form length intervals, aweakened longitudinal severing line 23a adjacent margin 28a, a series of pin feed apertures 30a and staples 2 la in the severable marginal portion of the strips, and staples 29a disposed along the transverse severing lines at the midportion of the strips. The stationery of Fig. 9 is adapted to be used with a modification of the feeding and severing device of the present invention, illustrated in Fig. 10.

' In the modified feeding and severing device shown in Fig. 10, a ring is provided on the end of the platen, similar to ring 31, except that pins 38 are omitted. The pins 44a carried by slide plates43a protrude through slots similar to slots 4| in the said ring, and the slide plates 43a are axially movable in grooves in the reduced end of a platen beneath each of the said slots in the same manner as slide plates 43. The tabs 41a on the said slide plates engage the groove 46a. on the fixed cam member 4511 which is of the same construction as cam member 45. A stripper 50a is shown for stripping the severed margin 28a from pins 44a.

On the lower side of the platen, from the point at which the stationery first engages the feed pins substantially to the writing line, indicated by the position of the type bar 49, the groove 46a, like groove 46, is parallel to a plane perpendicular to the axis of the platen. From this point onward, the groove diverges progressively from the end of the platen for a short distance. Beyond the point where the stationery is stripped from the feed pins, the groove converges again-to its inner position, becoming again parallel with a plane perpendicular to the platen axis, at the rear of the platen in advance of the point where the incoming stationery engages pins 44a.

Adjacent the opposite end of the platen, an annular series of fixed pins 13811 are provided which are adapted to enter apertures 3| a at the right-hand margin of the stationery illustrated in Fig. 9, when pins 44a. enter perforations 30a in the separable margin 28a of the stationery at the left.

As the stationery is fed beyond the writing line, pins 38a retain the inscribed portion of the strips in registration and alignment, while pins 44a move divergently outward relative to pins 38a, applying transverse severing tension at the weakened severing line 23a, and severing the bound marginal portion of the strip, containing apertures 30a, from the inscribed portion of the strip.

If desired, inscribed copies of any form length may be reinserted into the machine after severing them from the strip, and reregistered relative to the writing line of the machine byreengaging apertures 3la with pins 38a. However, the spacing of pins 38a from pins 44a determines the width of the stationerv which can be fed and severed, and if it is desired to use stationery of different widths, the axial position of at least one set of pins must be altered, or else the platen must be replaced by one having sets of pins of suitable spacing. For this reason, the arrangement illustrated in Figs. 1 to 8 is preferred.

The stationery per se illustrated and described herein forms the subject matter of my application Serial No. 420,783, filed November 28, 1941, which is a division of this application.
