signor, by mesne assignments, to Underwood Elliott Fisher Company, New York, N. Y., a corporation of Delaware Application January 2, 1936, Serial No. 57,166

4 Claims.

This invention has for one object, an economy in the use of carbon or manifolding material in typewriting machines, with particular reference to the use of what are known as carbon packs or rolls, the plies of which are interleaved with fanfold or continuous form webs of paper.

In the well-known Elliott Fisher fiat platen typewriting and billing machines, the manifolding material may be fed either transversely of the platen or writing surface, (as shown in the accompanying drawing, and in U. S. Letters Patent to Lentz, 1,677,971, July 24, 1928) or lengthwise of the writing surface, as shown in Letters Patent to Miller, 1,919,855, July 25, 1933, for instance.

The carbon rolls or packs usually comprise a plurality of manifolding sheets or plies from two to fifteen in number, each sheet or web being about ninety inches long.

In general, there are but five or six of these manifolding plies intercoiled on a single roll, which, when in use, are interleaved with the work sheets or webs, usually comprising a series of printed blank forms to be written upon.

In the side feeding type of Elliott Fisher machine, the manifolding plies traverse a path transversely of the path of the work sheets or webs, whereas in the end feeding type of machine, the work webs and interleaved manifolding plies form a pile traversing the same path longitudinally of the platen.

After one set of printed forms has been filled out, it is necessary to draw the work sheets forwardly until the forms just completed can be severed from the supply, a new set of forms being drawn forwardly between and relatively to the interleaved manifolding plies, which plies must remain in their adjusted positions, as the work webs are drawn over the platen.

And to insure that the manifolding plies extending across the platen shall remain in their proper positions, it is customary to either lead the free ends of such plies to and secure them in place on a re-wind roll, or, as herein shown, the free or leading ends of the manifolding plies that project beyond the side edges of the work webs may be confined between a suitable clamping bar and the frame of the machine.

Obviously, the use of a re-wind roll will result in the waste of those unused portions of the leading ends of the lengths of manifolding plies as extend from the edge of the platen to the rewind roll.

As the manifolding'material becomes worn, the clamp is released, and the worn areas are then drawn from beneath the work webs to substitute unused portions of the manifolding plies for the worn out portions, which worn portions are either coiled on the rewind roll, or severed from the supply of manifolding material and dis:

carded.

Also, when the last portion of the manifolding roll is brought over the platen, the stretches of plies between the supply roll, to which the eX-- treme ends of the manifolding plies are attached, and the adjacent edge of the platen are wasted, since it is still necessary to provide an anchorage for the manifolding material to prevent skewing thereof, and consequent injury, when the completed forms are withdrawn and severed from the supply of work webs.

Substantially the same considerations exist where the interleaved manifolding plies and work webs are fed in a pack longitudinally of the platen.

To be sure, there is not much waste of manifolding material at the free or leading ends of the plies, but the supply roll must, for structural reasons, be located so far from the first printing line on the platen, that there is a very appreciable Waste at the trailing ends of the plies, which, in a ten ply carbon pack, would amount to over 20%. I

To avoid the waste at the trailing ends of the manifolding plies, my invention contemplates the provision of a reach or spacing strip to afford an anchorage for the trailing ends of the manifolding plies, one end of the reach or spacing strip beingattached to the supply spool or reel, around which the reach is coiled, the trailing ends of the pack of manifolding plies being attached to the leading end of the reach or spacing strip, which latter is of such length as to extend from its point of attachment to the spool, to the margin of the platen or writing surface.

' Another object is to enable the trailing ends of the pack of manifolding plies to .be readily and quickly attached to the leading end of the reach or spacing strip.

To this end, the trailing ends of the manifolding plies are secured together, and the gathered end or stub thus formed is attached to one edge of a binding or connecting band, the opposite edge of which is attached to the leading end of the spacing strip.

A further object is to protect the gathered trailing end or stub of the pack of manifolding plies, as .well as to prevent injury to the manifolding plies from the means usedto secure the trailing ends in a pack. I

This result is readily accomplished by, first, attaching the connecting band to the gathered trailing end of the pack of manifolding sheets at such distance forwardly from the extreme end of the pack as to cover and overlie the gathered end of the pack, and secondly, to attach the oppcsite edge of the connecting band at such a distance rearwardly of the extreme leading edge of the reach or spacing strip as to enable such leading end to project over the gathered trailing ends of the pack on the side opposite that to which the connecting'band is attached, so that the trailing end of the pack is embraced between the binding band and the spacing strip.

Other objects and advantages will be more fully set forth hereinafter and particularly pointed out in the claims.

In the accompanying drawing,

Fig. 1 is an enlarged view in cross section, showing one embodiment of this invention applied to an Elliott Fisher machine, wherein the manifolding sheets are fed transversely of and across the platen or writing surface;

Fig. 2 is a perspective View showing a carbon roll pack; and

Fig. 3 is a greatly enlarged detail view in section, to show the means for, and manner of, attaching the gathered trailing end of the carbon pack to the leading end of the spacing strip.

The particular style of Elliott Fisher machine, in connection with which the selected embodimerit of the invention is illustrated, includes platen side rails I and 2 extending from front to rear adjacent the longitudinal side edges of the usual vertically movable platen 3, all as shown in U. S. Letters Patent to Foothorap, 1,569,917, January 19, 1926, and to Lentz, 1,677,971 aforesaid.

Spaced brackets 4, one only of which is shown, project from the left hand side rail i, and support between them the cylindrical reel or spool 5 formed with a non-circular bore to accommodate a correspondingly shaped shaft journaled in bearings in the brackets.

Heretofore, the trailing ends of the carbon manifolding plies have been directly secured to the periphery of the 'reel or spool in any convenient manner, as by spring clamps.

This invention contemplates the use of a reach or spacing web 5, wound upon the reel or spool, and of suflicient length, when unreeled therefrom to extend from the spool to the adjacent edge of the platen or writing surface, irrespective of the distance between the spool and the platen.

The inner end of the reach or spacing web 6 may be secured to the spool or reel in any convenient manner, the plies of manifolding material I being connected to the leading end of the web, which web is of some flexible, inexpensive material as kraft paper, for instance.

While the connection of the manifolding plies to the reach or web may be effected in many ways, I prefer to effect such connection in a manner substantially like that shown in the accompanying drawing, wherein the trailing ends of the superposed manifolding plies are secured together by stapling or stitching, as shown at 8, to form a gathered end, the stapling or stitching operating to bind the manifolding plies together as a unit, and thereafter, to attach to one face of the "pack of manifolding plies a binding band 9, which. preferably extends forwardly of the manifolding pack to a point slightly beyond the line of stitching or stapling 8, so as to cover the latter. The binding band 9 extends rearwardly of the extreme ends of the manifolding plies or of the trailing end of the pack a sufficient distance to form a tab for attachment to the leading end of the spacing strip 6.

Conveniently, the binding band 9 may comprise a strip of tough and flexible material, as the usual adhesive tape coated on one side for attachment at its forward portion to the trailing end of the pack of manifolding material, and at its rear portion to the leading end of the reach or spacing strip, the heavy black line H], in Fig. 3, indicating the adhesive coating.

To protect thecoiled manifolding plies from mutilation or indentation by the stapling or stitching 8, the rearwardly extending tab portion of the binding band 9 is attached to the leading end of the reach or spacing strip at such a distanee in rear of the extreme leading edge thereof as to leave a projecting portion arranged to extend along'the'opposite side of the trailing end of the carbon pack from that to which the binding band is attached, to a point slightly in advance of the line of stapling or stitching, to form a protective, apron, the gathered end of the carbon pack being, in effect, embraced between the binding band and the projecting end or apron cf the reach, respectively.

Of course, the trailing ends of the manifolding plies could be pasted together, but the stapling or stitching is much quicker, and more easily performed.

In use, the leading ends of the manifolding plies l are led through a suitable slot or opening H in the adjacent side rail 1, and over a sup: porting guide l2, interposed between the inner face of the siderail 'I and the adjacent edge of the platen 3, and thence across the platen, past the opposite side rail 2 and partway down the outer face thereof, to which the leading ends are clamped by a suitable pressure bar l3 having a severing edge M, an earlier form of which is shown in patent to Foothorap, 1,569,917, January 19, 1926, for instance. 7

Prior to the application of the pressure bar l3 to the free or leading ends of the plies of manifolding material forming the carbon pack, the continuous form webs l5, are unwound one at a time from their respective rolls supported at the rear of the frame (not herein shown, but disclosed in Foothorap, 1,569,917) and drawn forwardly along the platen or'writing surface, where they are interleaved with the manifolding plies, commencing with the lowermost, after which the manifolding plies are drawn taut, and the clamping bar or member I3 is applied to the free ends helpful "in preventing wrinkles or mutilations of,

the-plies as the continuous form webs are drawn forwardly therethrough after being printed.

When the leading ends of the manifolding plies have become too worn, the clamp I3 is released ,as well as the friction brake for the supply roll and the plies drawn to the right (in the drawing) to substitute fresh transfer areas for the worn areas, the friction brake and clamp reapplied, and the worn out portions of the manifolding plies severed from the supply by tearing oif along the cutting edge M.

It will be seen that this invention enables practically the entire length of the manifolding plies to be used, without waste, since, as shown, the gathered end of the pack of manifolding plies can be fed to the margin of the writing surface. Also the trailing endsv of the manifolding plies can be secured together, and the binding or connecting band attached to the gathered end of the pack and to the leading end of the spacing strip or reach with a minimum of time and by unskilled labor.

When the entire usable portions of the carbon sheets or manifolding plies have become exhausted, the operator will tear across or rupture the adhesive tape constituting the binding band, i

to enable the detachment of the stub or trailing ends of the carbon sheets from the leading end of the spacing web or strip, so as to utilize the spacing web for the attachment thereto of a new pack of manifolding material. 1

Changes and alterations may be made in th means for securing the trailing ends of the manifolding plies together to form a pack and in connecting such pack to the spacing strip or reach without departing from the spirit and scope of this invention.

What I claim as new is:

1. A multiple manifolding ply holder comprising a plurality of superposed manifolding sheets having leading ends and trailing ends, the sheets attached together near their trailing ends to form a pack; a binding band attached to the upper face of the uppermost manifolding ply of the pack along the secured edge thereof, and extending over the uppermost sheet to a point slightly beyond that at which the manifolding sheets are secured together; the binding band extending in the opposite direction past the secured edges of the manifolding plies to form a tab or extension; a flexible spacing strip to the leading end of which the tab is attached at such distance from the free edge of the spacing strip that said free edge of the spacing strip extends beneath the lowermost ply, to a point slightly beyond the line of attachment of the manifolding plies, to form a protective apron.

2. The combination with a flexible spacing strip; of a plurality of superposed manifolding plies having leading ends and trailing ends, and attached together near their trailing ends to form a pack; a binding band attached to one sideof the gathered ends of the pack, and overlying the line of attachment of the manifolding plies to each other, the binding band extending beyond the gathered ends of the plies' for attachment to one face of the free end of the flexible spacing strip at such a distance from the extreme free edge thereof that'the free end of the strip can extend slightly over the opposite side of the pack to form a protective apron, whereby the gathered edge of the pack is embraced between the binding band and the apron.

3. The combination with a flexible spacing strip; of. a plurality of superposed manifolding plies having leading ends and trailingendaand stitched together near their trailing ends to form a pack; a binding band attached to one side of the pack adjacent'the stitched edge, the binding band overlying the line of stitching and projecting beyond the stitched edge of the pack for attachment to the leading end of the spacing strip at such a distance from the free end of such strip as to constitute the free end an apron extending slightly past the line of stitching on the opposite side of the pack.
