'nrmsnn REEL.

Application filed A rnza, 1926. Serial No.'10'4,o15.

The main object of this invention is to provide a device applicable to typewriters I which supports an eraser at a position ad'- jacent the typewriterand permits adjustment' of the'eraser to any position uponthe cylinder. H v

fAnother object is ,to provide an eraser reel which is mounted "uponYthe frame of a typewriter andpermits extensibility er a cord from which an eraseris suspended to, any position on the typewriter cylinder, and

immediately after release of the, eraser, the latter is retracted toward the reel wherelt remains 1n convenlent posltion until it is again used. v p I Still another object of the invention is Referring'briefiy to the drawing, Figure 1 is a perspective view, showing acorner of a. typewriter having the eraser reel mounted in place thereonf I 1 Figure 2isa.longitudinalsectional elevational view of the reell for the typewriter eraser.

Figure 3 is an end elevational view of Figure 2.' I

Figure 4 is a top plan view of Figure 2.

Figure 5 is a front elevational view of a modified type of device. i

'Referring in detail to the drawing, the numeral 10 indicates the side, of a frame which bounds the keys 11 on three sides. Within the area bounded by this frame, the space bar 12 and other movable elements are depressible. On the side of the frame, a casing, consisting of two members, a lower cap 13 and an upper cap 14 is mounted.

The bottom of the lower cap13 has a post 15 extending upwardly into the chamber 16 formed by the'upper and lower caps. The. upper cap has a screw 17 which shoulders in the roof of theupper cap and is engaged in a threaded opening in the post 15 for the purpose of securing the upper and lower caps to each other. A drum 18 is mounted rotatably on the shank of the screw 17 and has the coils 19 of an endless cable wound upon its periphery. v The drum 18 is open at the bottom so that it can receive the spiral upwardly bent hook 25.

26 having a hook 27 "forming part thereof is fixed in an adjustable manner uponfthe The tongue 26 is supported upon studs 28 and 29 which project upward 1y from the roofof the cap '14: and the up? per ends'of these studs haveinclined edges *tongue 26 is slippedl length of the tongue 26, an opening is pro: vided thru which a reduced portion ofthe screw is rotatably 'mounted. Said screw is provided with a spring 20, oneend of which is attached tothe drum, the opposite end being secured to the post 15. The end of the cable 19 coursing from the periphery of the drum 18 emergesfrom the casing thru an opening 21 and has a fastening means'22 attached there} to cwhich may be secured in an opening formed in the 1 usual type of typewriter eraser 23. 1 3' g I The typewriter reel, consisting of the casingand its contained elements, isadapted to behdetachably mounted upon 'anytype of typewriter frame. "This mounting means consists of a rigid tongue 24; which projects radially from the sideof the bottom cap l3 and its extending end is formed into an A similar tongue upper cap 141.

which end T abruptly, as illustrated in Figure 2. Aroundjtheseistudspa housing consisting ofside walls 30 and a roof-31, is formed.

A pair of, studs 32 and 33-aremounted on this roof '31 andYeXtend downwardlytherefrom, being separated by a space from the lower studs 28 and 29into which space the Intermediate the threaded shank 34 of a head 35' which rises above the roof 31 of the housing and is adapted to be manipulated by the fingers, when mounting the device upon a typewriter by deflecting the tongue upwardly or downwardly to vary the distrance between the hooks 25 and 27 of opposmg tongue members. The reduced portion of the shank '34:, which is rotatably mounted in'the tongue 26, has a head 36 formed thereon and the threaded shank 34: is rotatablyand threadably mounted in an opening formed in the roof 31. 3 i e y The device comprises a typewriter reel which at all times positions, an eraser in the same place. In use, the eraser 23 is grasped and pulled on until the cable19 itselfito permit the eraserto be placed over the position where it is desired to be used After use of the GTELSQl',-'l lh6 same is released from the hand and'the spiral spring unwinds u-l i),

upwardly or downwardly according 20 being tensioned by paying out of the cable 19, yieldably rotates the drum 18 in an opposite direction and again winds the cable 19 upon the drum 18, thus automatically removing the eraser from the position in which it was used to its position beside the side 10 of the typewriter frame. The means for niountin the reel to a typewriter frame is made adpistable to con ipensate for various heights of frames on different types of typewriters. T his means includes the rigid tongue 2% inounted on one cap 15 and a'flexible tongue 26 which is sup ported between bottom studs 28 and 29 and upper studs and 33. The portion of the tongue 26 be: tween the studs 28 and 29 is flexed either tothe rotation of the shank 8aof the screw. This causes flexing in one direction or the other of the projecting hook end 27 of the screw and by this flexing, the distance between the hooks 2 5 and 27 is varied. When desiring to reduce the distance between the hooked ends of the tongues, the shank 34: of the screw is raised and when increasing this dis tance, opposite rotation of the shank 34ris required.

Figure 5 represents a modified. type of de vicehaving some parts thereof similar to that of the preferred form, which similar parts will be numbered by the same numerals. The upper member 1 1! is provided witlra pair of lugs 36 and 37 which have aligned threaded openings therein for reception of a screw 38 having a hook 39: at one .end and ahead $0 atits opposite end. By turning or rotating the'screfw 38, the hook 39 is brought into engagement with the part of the typewriter to which the device is to be mounted. 7

It is to be noted that certain changes in form and construction may be made withoutdeparting' from the spirit and scope of h -inven o I claim 1. In a device of the class described having a casing, means onsaid casing for mounting the device on a typewriter comprising a rigid tongue extending from the bottom of said casing, a flexibletongue extending -from the top of said casing, said tongues being aligned, studs having sharp edged upper ends supporting said flexible tongue, a housing eIlClOSing one end of said tongue, said tongue when depressed between said studs deflecting said tongue away from the rigid tongue, a screw shank thread-able in said housing having its end rotatably mounted in said tongue, said screw being adapted to deflect the tongue away from the rigid tongue by deflecting the flexible tongue downwardly between the. studs, and means for flexing said tongue to decrease the dis tanc'e between the rigid tongue and the flexible tongue.

2. In a device of the class described having a casing, means on said casing for mounting the device on a typewriter. cornprising a rigid tongue extending from the bottom of said casing, a flexible tongue extending from the top of said casing, said tongues being aligned, studs having sharpedged upperends supporting saidflexible tongue, a housing enclosing one end of said tongue, said tongue when depressed between said studs deflecting said tongue away from the rigid tongue, ascrew shank threadable in said housing having its end rotatably mounted in said tongule, said screw being adapted to deflect the tongue awaytrom the rigid tongue by deflecting the flexible tongue.

downwardly between the studs comprising additional studs mounted in said housings above the first-named studs, said additional studs having inclined lower edges and being spaced-apart from the first-named studs.

In testimony whereof I aflix my signature. J TIRITTERQ
