To all whom it ma concern:

Be it known t at I, Gnnccan SMEDAL, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of Wisconsin, ha \e invented certain new and useful Improvements in Attachments for TypeJVriters, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain new and useful improvements in attachments for typewriters, and of that type shown and described in Letters Patent granted to me May 12, 1914., Number 1,096,202.

.-Mypresent invention has forits object certain changes 'in construction and arrangement which will readily adapt the attachment to typewriting 'n'iachinesol varying constructions and dimensions, and also to dispense with the peculiarly constructed side members shown in the said patent; and to render my. presentimproved structure adaptable for use in connection with a typewriting machine by means independent of the side members referred to.

A further object of the invention is to so construct the attachment that the frame carrying the paper rolls will be automatically shifted laterally in accordance with the movement of the t 'pewriter carriage.

With these on s in view my invention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully described and shown.

In order that those skilled in the art to which my invention appe'rtains may know how to make and use my improved attachment, I will proceed to describe the same referring by numerals to the accompanying drawings in which,

Figure 1 is a front elevation of the attachmentwith two rolls of paper secured therein, Fig. 2 is a rear elevation of the same, Fig.3 is an end or side elevation showing it n operative relation with a typewriting ma chine. Fig. 4 is a view similar to Fig. 3, but showing only one roll of pa or in place, Fig. 5 is a central longitudinal, section of the attachment disengaged froma typewriting machine, Fig. 6 is a transvers section on the line a e of Fig. 5 and; Fig. 7 is a perspective view of an adjustable bifurcated, or forked device, adapted to connect the paper roll frame with the paper carriage of a typewriting mach ne roll frame. The paper rollcarrying'means includes an outer frame formedof end members 5, a top longitudinal member 7 and a lower longitudinal member 4. This lower longitudinal member 4 is formed .by two bars, each of which is designated 4 in the drawings, these bars meeting at the middle and being downwardly turned to provide legs 3 extending down into the hollow post 2. Those vertical legs 3 are secured to each other by screws 6; the heads of which lie within the space between the edges of the angle iron composing the legs, as clearly shown in Fig. 5. The-bar 7 is a flat bar and is secured at its two ends to the end members 5 by suitable screws 8. I of course do not wish to be limited to the exact construction of this frame.

The construction so far described constitutes, arectangular fr me with a vertical leg adapted to be supported at any desired elevation within the post 2. The flat bar or top of this frame is formed with a longitudinal track or groove-9, '(see Figs. 5 and 6), in itsundcr side for the purpose presently explained, and to the bottom of the frame is secured by scrbws 10, or otherwise, :1 bar ll, formed on its upper surface with a track or groove 12, similar to a like feato re in the upper bar. The traveling frame for carrying, one or more rolls of paper is rectangular in form, consisting of a bottom rod l3, two ends 14, and a top bar 15, the latter secured to the ends by screws 16, passing through slots 17 in the returned extll'li'lltiCS thereof. in order that it may be fen/lily adjusted with reference to the bottom bar of the frame, to thus permit the inner traveling frame to be removed from the outer frame. Secured within the top and bottom of" this paper roll frame at suitabio localities are antifrictiou wheels 18, adapted to travel in the tracks orgrooves 9 and 12. The ends 01" the paper roll frame are formed with series of equidistantholes 19, for the reception and support of a paper roll shaft 20, with one end threaded as shown at 21, and the other end formed with a square head 22 adapted to be held in position by the right, angle edges of the end 14 of the frame. 3

23 is a nut with milled circumference and with a shank adapted to extend and lie within the edges of the opposite end 14, when the nut is in position to hold the shaft in fixed relation with the fralme. Arranged upon the shaft 20, are two movable disks or heads 24, formed with hubs 25, provided with set screws 26, by means of which said disks or heads may be held in any desired adjusted positions. From the construction just described it will be obvious that these disks or heads may be adjusted upon then shaft 20, to hold a .roll of paper of any width against longitudinal movement on its shaft;

27 is a roll-of paper with a Wooden box or center, mounted rotatively upon the shaft 20, and 28 is a pressure roller rotatively mounted in the bifurcated end or tail of a flat steel spring 29, the opposite end of which is bent to conform with, and is longitudinally adjustable upon the top of the paper roll frame as clearly shown in Fig. 6. The pressure roller is equipped with a friction surface, preferably roughened rubber, and the tension of the spring (which as will be seen is curved), may be adjusted by means of a stiff disk 30, and a set screw 31, in an obvious manner.

As shown in the drawings the attachment may be provided with only one or with two rolls of paper when in the latter case, a carbon copy if desired is secured by means of a carbon sheet interposed between paper fed from the rolls.

The two frames of the attachment are shown as at slight angle to a horizontal plane in order that when the paper roll is being carried by the typewriting machine carriage to the left, the paper roll frame by reason of its inclined relation and its antifricti'on wheels will by gravityktravel coincidently with the machine carriage and relieve it from any undue strain. If however for any reason it should be desired, the

attachment frames may be arranged in horizontal plane without departing from the spirit of my invention.

From the construction so far shown and described, it will be seen that the attach- 'ment per-8e is entirely independent of a typewriting machine, and in order that it may be readily placed in operative relation with machines of different makes, I provide a link or bridge 32, such as shown in Fig.7, one end of which is bifurcated as seen at 33, and adapted to straddle or embrace the end of the paper roll frame, and the opposite end fashioned in any suitable manner for convenient connection with the paper carriage frame of a typewriting machine.

While. I have shown the frames and support composed of Inetal in the form shown in cross section, and prefer such form as securing maximum strength and rigidity with minimum weight, I do not wish to be confined inthis particular as any other suitable form may be used if so desired; nor do I Wish to be confined to the use of any particular material, so long as the character of the same adapts it to the uses required.

In lieu of using two rolls of paper if desired and as hereinbefore referred to, a single roll with two larianae of paper and with a carbon sheet intermediate, may be employed as stated in theLetters Patent granted to me and hereinbefore referred to, and while I have shown the attachment mounted upon a; single pedestal it may be varied in this detail. if deemed desirable without departing from my invention.

It will be readily seen from what has been said that my improvement is not only readily adapted for use with any make of typewri ting machine accordingly as the connection may be designed, but that by reason of such connection the paper roll frame with the roll mounted thereon is movedlongi tudinally and positively by the carriage of the typewriting machine, which is relieved from any undue strainby the paper fed from the roll, and likewise the paper not being under undue strain is relieved from the tendency of being warped as it is fed from the roll during the printing operation. It will also be seen that when it is desired to use the typewriting machine in the usual manner with separate sheets of paper, it will only be necessary to move the attachment away from such machine, releasing it from the bifurcated connecting link or latter although attached to bridge, which the machine will in nowise affect its use.

Having described the construction, operation, and advantages of my improved attachment, what I claim as new and desire to secure by Letters Patent isc 1. An attachment for use in connection with typewriting machines consistin of a rectangular frame mounted upon a weighted pedestal, the top and bottom of said frame formed interiorly with longitudinal grooves or tracks, in combination with a rectangular frame provided with an adjustable shaft having rotatively mounted thereon a roll of paper, and antifriction wheels journaled in the top and bottom of the paper roll frame and adapted to travel in grooves or tracks in the top and bottom of the roll frame support, substantially as and for the purpose set forth.
