TYPEWRITER ATTACHMENT.

Application filed January 19, 1921. Serial-No. 438,467.

6 State of Illinois, have invented certain new and useful Improvements in Typewriter Attachments, of which the following is a specification. f

This invention relates to new and useful 10 improvements in typewriter attachments,

more especially to a paper roll feeding attachment, and the primary object of the inve-ntion is to provide a simple and inexpensive attachment, applicable to any make of typewriter whereby paper may be fed from the rolls to the platen of a typewriter, thus eliminating the necessity of feeding separate sheets. y

A further object of-the invention resides in the provision of an attachment of extremely few and simple parts which may be quickly and readily applied or removed, when desired.

Still another object .of the invention re- 2 sides in the provision ofa means for locking the roll of paper to the attachment in such manner that said paper may beun-- rolled and fed to the platen of the typewriter as said platen rotates'in the operation of the typewriter.

A still further object resides in provid ing a device which is simple and durable in construction, inexpensive to manufacture, and one which will be very eflicient and useful in operation. a

With these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter 4o referred to and more particularly pointed out in the specification and claims. In the accompanying drawing forming a part of this application Figure 1 is a perspective view showing my improved attachment applied to use;

Fig. 2 is an enlarged detail section through the roll of paper, with parts shown in elevation; Fig.3 is a detail perspective view of a fragment of the main shaft;

4 isa perspective view of the lock- 1n sleeve removed;

ig'..5 is a similar View with the cylinder removed; and

Fig. 6 is a'pers ective view of the entire roll or cylinder orming the body of the pa er roll. v

n describing the invention I shall refer to the drawing in which similar. reference characters designate corresponding parts 00 throughout the several views, and in which 1 designates the. frame of 'a typewriter of any preferred make which has the carriage 2 operatively mounted thereon, said carriage being provided withthe usual platen 3. Bolted or otherwise similarly secured to the'framework of the carriage, rearwardly ofthe platen, are the upwardly f and rearwardly projecting supporting arms 4. These arms have sockets formed in the '70 upper ends thereof in which are removably mounted the Y-shaped trunnions or sup-- ports 5, the latter having bearing. balls, 6 therein to loosely and rotatably receive the cylindrical ends 7 of the shaft 8 which is designed square in cross section. One cyli'ndrical end of this shaft is threaded in place to the body thereof as shown at 9 so that the parts may be applied and removed, as will be hereinafter referred to, and colso hrs 10 are formed on the cylinder end 7 to abut the outer faces of the Y-shaped supports 5, wherebyto preventlongitudinal movement'of the shaft therebetween. The extreme ends of the shaft have the knurled lmobs 11 carried thereon whereby the device may be readily hand-operated when desired.

Carried on the shaft 8 is a c linder 12, the opening in which is rectangu ar'in cross section to. snugly receive the squared portion of the shaft 8, and adapted to be mounted onthis cylinder 12 is a roll of paper 13. This paper may be of any preferred size, according to the use to which the same is applied, and the same is preferably perforated as shown at 14 to be readily severed in sheets as the work thereon is completed. The pa er is preferably rolled upon the inner cy 'nder 15 formed preferably of cardboard, the latter beingopenings being disposed in predetermined positions and adapted for registration with similar openin s 17 formed in the .roll or cylinder 15. d squared sleeve 18 formed of spring metal is provided, the same having one end thereof slit to provide four spring arms 19, the ends of which are bent outwardl .to form locking fingers 20, as clearly s own in Fig. 4. This sleeve is applied to one end of the squared shaft 8 within the cylinder 12, the latter being constructed to receive said sleeve. This sleeve is forced into position within the cylinder so that the fingers 20 spring into openings 16 of said cylinder and simultaneously enter the o enings 18 of the roll or cylinder 15, carrying the roll of paper. The

sleeve 18 is locked into position by meansof a set screw 21 and when properly positioned locksthe roll of paper to the shaft so that the latter rotates in its bearings with the rotation of the roll 13.

In operation, after theroll of paper has been properly applied to the shaft 8, the latter is disposed in position on the supporting arms 4 and the paper from the roll 13 is drawn downwardly and fed to the laten 3 of the typewriter, being positioned or writing thereon, as clearly shown in Fig. 1 of the drawing.

After having set the device in this manner, it will be seen as the laten is rotated, the paper will be automatically fed thereto from the roll 13 and as each sheet has been completed the same may be severed from the roll along the perforated portions thereof.

Thus it will be seen that considerable time and labor will be eliminated in that the usual feeding of separate sheets of pa er to the machine will be unnecessary. oreover, it will be seen that this device will provide a means for economy and permit a greater amount of work to be completed than would ordinarily be accomplished through the old methods. I

It will still further be seen that I have provided a simple and inexpensive means for carrying out the objectsof the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion, and in the minor etails of construction may be resorted to without departing from the spirit or sacrificing any of the rinciples of the invention.

Having thus described my invention, what I claim 1s:

1. An attachment for use with typewriters combination with supportin or similar carriages, om rising a supporting means, a shaft rotatab y mounted in saidv supporting means, a paper roll on said shaft, and means for removably locking said roll on said shaft.

2. An attachment for use withtypewriting machine or similar carriages, comprising a supporting means, ashaft rotatably mounted in said supporting means, a cylin dercarried on said'shaft, a paper roll carried on said cylinder, and means for removably locking said roll to the cylinder.

3. An attachment for use with typewriting machine or similar carriages, comprising a supporting means, a shaft rotatably mounted in said supporting means, said shaft having a portion thereof designed rectangular in cross section, a cylinder mounted .on the rectangular portion of said shaft, a paper roll carried on said cylinder, and means to lock said roll to said cylinder.

4. An attachment for use with typewriting machine or similar carriages, comprising a supporting means, a shaft rotatably mounted in said supporting means, said shaft having portions thereof rectangular in cross section, a cylinder slidably mounted on the rectangular portion of said shaft, a paper roll mounted on said cylinder, and means to lock the cylinder against longitudinal movement on the shaft and simultaneously lock said roll to the cylinder.

5. In a device of the class described, the means; of a rotatableshaft having a portion thereof designed rectangular in cross section, a cylinder slidably mounted on the rectangular ortion of the shaft, a paper roll moimte .on said cylinder, and a locking sleeve carried on said shaft retaining said cylinder against longitudinal movement on the shaft and sirdnultaneously securing the roll to said cylin- 6 In a device of the class described, the combination with supportin means; of a rotatable shaft having a portion thereof designed rectangular in cross section, a cylinder slidably mounted on the rectan ar por tion of said shaft and provided with a pluralit of radial openings, a tubular member slida ly mounted on said cylinder and provided with additional openings adapted to register with the aforesaid openings of the cylinder, a paper roll applied to said tubular member, a locking device removably applied to the rectangular portion of said shaft and provided with means to lock the cylinder against longitudinal movement on the shaft and simultaneously secure said tubular member and the paper roll to said 0 linder.

7. In a device of the class escribed, the combination with supporting means; of a rotatable shaft having a portion thereof designed rectangular in cross section, a cylinder slidably mounted on the rectangular portion of said shaft and provided with a plurality of radial openings, a tubular member slidably mounted on said cylinder and pro- 5 vided with additional openings adapted to register with the aforesaid openings .of the cylinder, a paper roll applied to said tubular member, and a sleeve removably applied to the rectangular portion of the shaft and havthe same one to the other and simultaneously lock said cylinder against longitudinal movement on the shaft.
