TYPEWRI TER ATTACHMENT Filed Jilne so, 1935 2 Sheets-Sheet 2 fi i pm ATTORNE Patented Nov. 24, 1936 UNITED STATES PATENT 10 Claims.

This invention relates to writing machines and particularly to a holder for a paper supply of continuous series connected stationery to be mounted directly upon a typewriter. It is recognized that there have been numerous holders for supplies of paper or record material, some of which have been mounted for to and fro travel with the typewriter platen carriage, while others have been stationary and provided with various devices for withdrawing and guiding the record material to the platen roll. Such devices have usually been of expensive construction and becupy considerable space, more than is available on an ordinary typewriter desk or stand.

The present apparatus contemplates an adjustable holder for continuous strips of record material to be stationarily secured to the frame of a typewriter and an upstanding guide frame carried by the traveling platen carriage of the typewriter, of sufficient height that the twisted or askew position assumed by the supply portion of a strip of record material, as the traveling platen carriage reaches the limit of its travel, will not be transmitted to that portion of the supply strip in proximate relation to the platen-roll.

The object of the present invention is to simplify the construction as well as the means and mode of operation of stationery holding and supply-devices for will not only be c eapened in construction, but will be more eificient in use, effective in operation, easily applied to ordinary commercial typewriters, and unlikely to get out of repair.

A-further object of the invention is to provide a construction which will be compact in form and capable of being easily contained in an ordinary typewriter desk.

A further object of the invention is to provide a stationery holder or receiver for a paper supply directly applicable to a typewriter structure and a guiding means intermediate the holder or receiver and the platen roll of the typewriter which will insure suflicient length of supply strip between the holder and the platen roll to obviate any uneven tension, pulling or twisting of the supply material adjacent to the platen roll and conse-' object of the invention is to provide equivalents, as hereinafter described and set forth in the claims.

In the accompanying drawings, wherein is I shown the preferred but obviously not necessarily H the only form of the embodiment of the invention, Fig. 1 is a side elevation of a well known typewriter constructionto which the present initing machines, whereby they to be closed over the typewriter or a cover of vention has been applied. Fig. 2118 a perspective view, showing-the relation of the paper holder and guide means -to the typewriter structure. Fig. 3 is a perspective viewof the paper guiding devices Fig. 4 is a perspective view of the paper supply holder. Fig. 5 is a perspective View of the base or supporting member.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the accompanying drawings, I is a typical writing machine of which 2 is the usual reciprocatory platen carriage and 3 the platen roll carried thereby.

Secured to the rear of the typewriter i is the paper supply holder, forming the subject matter hereof. Such-paper holder includes the base or supporting member 4 which, in the present instance, is a plate having its rear margin bent to form an upwardly and rearwardly extending flange 5. At its forward edge the base or supporting member 4 is provided with clamps 6 by which the base is fixedly, but detachably, engaged with the frame of the typewriter I.

'Detachably mounted upon the base 4 is the paper supply holding member which consists of a metal plate bent into angular formation to afford a back panel I and a shelf-like extension 8 at the bottom of the back panel I, the forward margin of such shelf 8 being preferably, though not necessarily, deflected upwardly as at 9. This paper holder, comprising the unitary back panel I and shelf 8 is mounted in a rearwardly inclined position upon the base or support t whereby the back panel I is disposed in an upwardly and rearwardly inclined position while the shelf 8 projects forwardly and upwardly. The unitary holder is detachably engageable with the base 4 by any suitable means which. for convenience and economy of manufacture, are preferably, though not necessarily, headed studs I0 upon one of these members which engage within key-hole slots II in the other member. H

The back panel 1 of the paper holder is provided with transverse slots [2 within which are adjustably mounted vertical guide flanges [3. The flanges l3 are adjustable toward and from each other to agree with the lateral dimensions of a packet of record material positioned upon the shelf 8 and resting against the back panel 1 intermediate such fianges l3. The paper supply holder is stationary relative to the typewriter I. If the paper supply should be drawn direct from the holder or carrier to the platen roll 3, the movement of the traveling typewriter carriage 2 would pull the paper strip askew, first in one direction and then in the other as it approached the limit of its travel in either direction, and so cause the supply strip of record material to be torn or cause undue pulling strain which would tend to induce uneven tension upon that portion engaged by the platen roll and so cause misalignment or improper feeding of the material through the writing machine. To obviate such condition by insuring an ample length of paper supply strip between the holder and the platen roll, guiding means is mounted upon the traveling carriage over which the supply strip passes. As illustrated in the drawings, this guiding means comprises a pair of upwardly extending parallel arms l4 hinged at IE to brackets I6 secured to the traveling carriage of the typewriter I. The brackets 5 are shaped and proportioned according to the construction of the particular typewriter to which they are to be applied, and are preferably provided with holes registering with corresponding holes in the typewriter platen carriage whereby attachment screws, forming part of the typewriter structure and provided at the time of manufacture thereof, may be utilized for the attachment of the brackets l6 for support of the guide arms l4.

At their upper ends the guide arms I4 carry a transverse rod I! which is preferably, though not necessarily, longitudinally adjustable in the side arms I4 to which it is secured by set screws 3. The paper supply strips, from the holder or carrier at the rear of the typewriter, passover the rod I! and thence downwardly to the platen roll 3. There is thus insured an ample length of material between the holder andthe platen roll to accommodate any twisting movement or lateral pulling action due to the to and fro travel of the platen roll carriage without transmitting such pulling strain to the platen roll itself. Limit fingers I9 are provided and slidingly adjustable upon the rod I! to retain the paper strip or strips in proper relation with the platen roll. These limit fingers I9 project inwardly toward each other and in overhanging relation with the paper strip or strips, from supporting hubs or collars 20 mounted upon the transverse rod I! to which they are secured in proper relatively adjusted position by set screws 2|.

The present paper holder is especially designed to accommodate continuous or series connected stationery which has been folded to and fro in Zigzag formation into a supply packet. It is es- 1 pecially desirable and applicable to the use of manifolding material comprising superposed alternating strips of record and transfer material folded in such zigzag formation into a supply packet of multiple strips.- While in practice these strips are usually marginally punched for use with a pin type platen roll whereby absolute reg-' istry of superposed printed forms upon the several strips is insured, the use of such pin type feeding devices and marginally punched paper is not material nor essential to the function of the paper supply holder and guiding means, but these may be employed with an ordinary friction feed typewriter or other writing machine.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the

invention has been described in language more or less specific as to structural features, it is to I be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended clalms.
