My invention relates to improvements in methods and means for feeding a plurality of long strips of printed forms into a typewriter, said strips being superimposed on.

each other and interleaved with carbon sheets, whereby the filling in of the successive forms with typewritten matter, and the production of the requisite number of carbon copies may proceed practically continuously.

The invention is an improvement over the structure of my co-pending application Serial No. 21,502, filed April 8, 1925, now Patent No. 1,699,794, dated J anuaryv 22, 1929.

The general object of the present invention is to provide a method and means for effecting this result.

. Contributory objects are the following:

To provide means for folding over the first set of forms against the second set of forms, drawing the loops of paper thus formed around the platen by rotating the same backward by hand, typing the forms in the usual manner, pulling them forwardly over the carbons which are held in place against forward movement and cutting off the finished forms.

To provide means for clamping the paper against the platen as the latter is rotated reversely by hand whereby the loops are formed automatically when the paper is pulled down past the feed rolls.

To provide a platen having a recess in which the loops are received.

To provide overhanging supporting rods to which the carbon sheets may be readily attached.

To provide these improvements in the form of an attachment which may readily be applied to any standard typewriter by merely substituting a special platen for the one m use.

To provide a knife for ished forms.

Other objects and advantages will be a parent from a consideration of'the embod ments of the invention illustrated in the drawings, in which continuous typing is ac complished merely by turning the knobs on the platen shaft to rotate the platen first in the reverse direction from that in which it rotates step by step during the typing opercutting off the finning the operation;

atiorr; then after typing the forms pulling out the paper and tearing of? the forms without 4 is a frontelevation bf the platen; Flg. 5 is an enlarged elevation of one of the duplex bars for supporting two of the carbon sheets;

Fig. 6 is an elevation of a modified and preferred form of duplex bar support;

Fig. 7 is an end View thereof; and

Fig. 8 is a small diagrammatic view illus trating the operation of the device.

Referring to the drawings, 1 represents an ordinary typewriter which may be of any approved design, the one selected for illustration being well known. In addition to the usual parts it has a knife 2 in front of the platen 3. This platen is mounted on the usual shaft 4 having bearings 5 and the usual ratchet 6, the latter, however, being spaced from the end of the platen to provide a clearance between the two. A clamp bar 7 is pivotally supported on the platen having its ends 8 bent downwardly and then inwardly to form pivotal supports 9, received in end openings in said platen.

A plurality of metal frames or bars are provided for supporting sheets of carbon paper. They may be made in various forms and operated different ways. One of these carbon holders, see Fig. 5, consists of a small rod 10 passing through an opening in the platen and having detachable ends 11 extending upwardly and then inwardly to form bars 12 and 13 spaced from each other and supported by one end only, whereby they overhang the platen. Each of these bars is adapted to support a sheet of carbon paper,

as hereinafter explained. A second similar frame comprises the rod 14 having bent ends 15 and overhanging bars' 16 and 17, each 'of the latter adapted to support a sheet of carbon paper.

The clamping frame and the two carbon frames are each provided with pins 18, 19.and 20 (Figs. 2 and 3) which limit their movement in one direction. They may be swung in the other direction, however, into the recess 21 in the platen as shown in Fig. 2.

In using the machine a plurality of long strips of printed forms are pulled forwardly, face downwardly, along the top of the platen. Horizontal bars 12, 13, 16 and 17 to each of which one end of a sheet of carbon paper is secured, are placed between said strips of printed forms. Theends of these supporting rods extend beyond the lateral edges of the strips of paper and are then attached to the rod 10. In the form shown in the drawings, Fig. 3, provision is made for five such printed forms 22, said printed forms being stored at the rear, in the usual manner. Provision is made in this instance for four sheets of carbon paper 23, the rear end of each of which is looped around one-of the bars 12, 13, 16 or 17, the carbon paper being pasted to itself to form an open loop, whereby these loops may readily be slipped over said rods, half of them from one end and the other half from the other end thereof, as will be understood from an examination of Figs. 4 and 5. The sheets of carbon paper are a little shorter than the height of the superimposed forms whereb the latter initially extend beyond the car ons as shown in Fig. 3 to facilitate grasping the same by hand.

The preferred form of carbon support is shown in Figs. 6, 7 in which the transverse rod 24 has its ends bent upwardly, one of them being bent outwardly, and the other being bent inwardly as at 25 and 26, these bent portions constituting guides to receive the detachable rods 27 over which the carbon paper is slipped. Many platens are hollow thus permitting the bar 24 with its upwardly bent ends to pass through the same before the end plates are secured thereto. The-rods 27 are arranged one in front of the other.

The printed forms are guided in their movement toward the platen by a member 28 secured to the carriage and havin its ends bent upwardly to form vertical gui es. Also the clamp bar 7 is struck upwardly as shown at 29, leaving a pair of shoulders which guide the paper over the platen.

In using the typewriter, the operator turns the platen by hand in a direction the reverse of the usual operation, whereupon the clamp 7 and the carbon supporting frames are moved toward the laten. In the particular mechanism shown erein the said parts tend to swing to the rear along the arc of a circle as the forward movement of the paper is obstructed more or less by the upper end of the two spring pressed feed roll supports 30, which carry the feed rolls 31 and the knife 2, and thus the paper is automatically clamped to the platen at a predetermined distance from the end of said sheets, i. e. a distance approximately equal to the length of a printv ed form. Although the clamping member moves inwardly along the arc of a circle, it is evident that it may be caused to move inwardly in any one of a number of different carbons between the outer half of the sheets of said group. The inner half merely serve as a backing.

As the typewriter is operated in the usual way, beginning atthe top line to be filled in, the platen is rotated in the usual direction,

-i. e., forwardly, and the forms are gradually fed out of the machine until the bottom line is reached in which position the clampin bar and associated carbon holding bars wi have been rotated from the position shown in Fig. 2 almost to the printing line, after which the operator turns the platen by hand a little further in the same forward direction to feed the printed forms completely out of the machine. Thereupon the operator seizes the forward ends of said forms, which as stated, project perhaps half an inch beyond the forward end of the carbon sheets, about as shown in Fi s. 1 and 3, and by pulling said forms forwarglyflhe carbon sheets are left behind, being held in place by the transverse bars to which they are attached, so that said printed forms slide over the carbons leaving a second set of forms in proper typing position with reference to the carbons. The platen is then' rotated in the reverse direction, in the manner previously described, leaving the completed forms projecting from the top of the machine wlth no carbons between them whereupon they are seized and torn off against the knife 2, which is located just in front of the platen. T hetyping operation then proceeds and the o erations are repeated. Such rotation is ma e possible by virtue of the recess 21 into which the various cross bars swing, so that said cross bars and the paper looped thereover do not protrude beyond the surface of the platen to an objectionable extent. In other words, where a small number of carbon copies are to be made, one or two, it may be possible in some .to fall back in said recess independently cases to use an ordinary platen without a recess cut therein, as the projection caused by the loops of aper will ride under the feed rollers 31 which spring back sutficiently for the purpose. Said cross bars are arranger;

0 each other, and are arranged to lie side by side rather than one over the other so as to fitinto the available space very compactly.

The improvements may be applied to an 017- dinary typewriter merely by supplying a special platen, which may be placed in the bearings from which the regular platen has been removed to permit the use of my improved platen. Additional feed rolls are unnecessary as the paper loops areclamped against the platen by the pivoted clamp, which holds them in place without additional feed rollers. It will be understood that the printed forms in practice are very long, enough to supply several thousand individual'printed forms and are conveniently stored to the rear of the typewriter, whereby after said forms are once threaded through the machine with the carbon sheets between them, it is unnecessary to interrupt the typing operation, and thework may proceed as a continuous operation.

Another type of printed form which may be used is one having its alternate lateral edges joined, in a well known manner.

Although as shown in Fig. 2, the length of each printed form is less than the circumference of the platen, it is possible to use printed forms having a greater length, necessitating rotation of the platen more than a complete turn, particularly when the vertical height of the typing area is no greater than the circumference of the platen.

As will be seen in Fig. 2, the arrangement of the clamping bar and the carbon holding bars is such that said bars fold. into the recess in the platen in such a way that the paper does not project too far beyond the normal circumference of said platen. The carbon holding bars shown in this figure are arranged in pairs one over the other. In the referred arrangement shown in Figs. 6 and the carbon holding bars are not only arranged one over the other, but they are displaced circumferentially, that is, one is arranged in advance of the other, the rear one being the higher of the two and the end view of the support for the bars being V sha ed as shown in Fig. 7. When this V shape frame is folded rearwardly, the two bars lie nearer the surface of the groove in the platen. In other words, a smoother arrangement is presented when all the bars are swungback into the groove.

Instead of having a series of individual bars with end portions'extending at right angles thereto, a single structure may be provided at each end of the platen carrying not only the clamping bar but all of the carbon holding bars so that said bars maintain -a fixed relation as they swing up or down.

Although the devices shown are particularly useful in making a large number of carbon copies of typewritten matter, it is evident that the principle of operation is applicable to a single sheet of paper and a single carbon sheet, in which case only the clamp bar is necessary, the carbon sheet being secured to the clamp bar and thus arranged to make the necessary carbon impression when the single sheet of paper is folded back on itself. The carbon copy is thus made immediately to the rear of the area on which the original impression is made and on the opposite side of the paper, in which case the strip of paper is drawn'forwardly far enoughto withdraw both the original and the carbon, in other words, twice as far as in the cases previously described.

By using the attachment described, it is also possible to obtain a tabulation of the totals of the individual printed forms, where such is desired, merely by securing an additional narrow sheet of carbon paper to the clamping bar and passing an additional strip of paper under said clamping bar and over the upper printed form. After each operation this strip of paper, which may be a wide sheet or merely a narrow strip at the right hand side of the machine, is pulled forward a short distance, for example a half inch or less, enough to receive the successive totals thereupon, which appear in the reverse order, i. e. the totals read from the bottom up. If it is preferred to print the totals in consecutive order from the top down, an additional carbon holding bar may be mounted on the platen to support a sheet of carbon paper between the top printed form and the tabulating sheet which passes under the clamping The terms top, bottom, front, rear, horizontal, and similar terms used herein as descriptive of the particular embodiment of the invention shown are to be understood as used for convenience in a relative sense and not in a limiting sense. In general, various changes may be made in the form and location of parts and in the general design of the machine without departing from the spiritof the invention as expressed in the appended claims.
