p This invention relates to improved attach- IIIGIItSfQI typewritersof theform generally employedforgclerical andfoflice work in general, and the. invention has [reference to a simple appliance constituting a copy holder and designed to accdimnodate different characters ofwork in amanner to facilitate copying by the operator of the machine. Y

Briefly stated, the inventive conception 1 comprehendsastructure characterized. by a worksupporting and guiding rack disposed in a substantially horizontal elevatedposi} tion and means for attaching said rack to a conventional typewriterwithout requiring a1- teration of the existing or stock parts of the typewriter machine, said means being such 'asto suspend'the rack at a point with respect to the keyboard to expedite and facilitate copyingwhile the copy of the workis held in a convenient position for such service.

novel feature is found in the utilization of a rack includingasubstantially horizontallyextending ledge and an associated backing member wherein said member includes vertically spaced longitudinally disposedpar- 'allelslats or strap members whereby tofpen mitconvenient copying from a book supportis'i o ed on said ledge or convenient copying from relatively long legal sheets the latter feature being desirable in: that it permits the sheet to be threaded through the slatsin avpositionto-hold "tlrigidlyan d to allow it tobefed by hand in a step by step manner. f 7 V. A further pointlof novelty is predicated rack to the typewriter,

Observing the end members from the rear as seen in Figure 5, it will be seenthat the 7 major part'of each member is formed from a single length of wire which includes alow- .er vertical leg portion 12 having an eye 13 formed atits bottom embracing the adjacent 7. The upper end of the part 12*is bentlaterally outward in a horizontal lineasat'lland bent at right angles and vertically as at 15 and then bent forwardly toprovidea suspension arm'l16 which overliesthe typewriterasseen'inFigure 1. l

The numern designates a sort of a diagonal-braceattached at itsupperend to the arm 16 and at itslower end to theleg 12 adjacent the eye 13, Thenumeral 18 desig- 'na te's a' substantially diagonal stay which at one en'dwraps aroundthe portion 14 as indicated at 19 toprovide a pivotalconnection which hasits forward end formed with an eye/ 20 to embracethe front legs8 of the typewriten Then'umjeral 21 designates a tierod between the two end members connected at its opposite endsto the leg 12 and which forms a connecting brace as shown 111 Flgure 5.

bent toprovide the arms 16 fQ Supporting the] rack 9 andthe remaining portion bent to provide attaching means for the feet 7 a of enab tay 181ml ng m ans pai a v forithe endm'embersg p H g V The rack 9 is "of composite structure and It; may thus be saidthat theso-called harness is'imadeup. of apair of duplicate end members including a single length. of wire roo tions 25 curled around the portions 22. The

uppermost strap orslat 26 has its upper longitudinal edge 27 bent around the bight as indicated in Figure 4,. and the ledge comprises a horizontal shelf 28 and a sub-stantially vertical portion 29, these parts 28 and 29 having bent knuckles 30 and 31 bent around the adjacent portion. F or instance, the knuckles 31 embrace the portions 22 while the knuckles 30 embrace the extremities of the aforesaid arms 16. Consequently, the ledge of this. rack constitutes the means for mounting therack, as a unit, on the arms 16. The slats 24 and 26 constitute backing members for the work.

The work may be a book which can be rested in the ledge and backed by the members 24 and 26. As before indicated however, it is possible to use long sheets of copy papers which may be passed upwardly through the several slats in a sort of threaded manner so that the sheet of paper may be held frictionally in place at the same time pulled by hand gradually upward as the copying wor proceeds until the end of the sheet is reached,

To facilitate this maintenance of long legal sheets in the rack, I provide a clamping plate 32 held in place by retaining bolts 33 andthumb nuts 34. The lower edge or lip 35 may be offset outwardly to facilitate insertion of the sheet of paper therebeneath. This clamping plate 32 comes in handy when using relatively short flexible sheets in the rack. Inother words it aids in holding the sheet nicely in place and the clamping- -plate .32 need be tightened only slightly so as to hold the paper frictionally and to permit it o be p le up. between the plates32 and adjacent. flapsor backing. straps 26;

The numerals 36idesignate end; clips whose side portions. areformed with coiled springs 37 embracing the portion 22 and anchored behind the slats 24 and 26 as indicated in Figure 4.

In practice, the eyes 13 are placed around the rear feet 7 of the typewriter and the stays 18 are. swung down on their pivotal connection 19 and the eyes. 20 are engaged around the front feet 8, This attaches the supporting frame on the typewriter so that the arms 16*ov'erly the machine as shown in Figure 3; This placesthe rack 9 in a con.- venient position to accommodate. various kinds of copyworkto expedite copying while holding the work in a convenient plane position.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

WVhile the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field 0finvention claimed may be resorted to if desired.

7 I claim a v 1 In a copy holder of the class described, a rack, and means for attaching the rack to a typewriter, said rack comprising a substantially U-shaped member, a plurality of spaced parallel horizontally disposed strap members. carried thereby, and a forwardly projecting substantially horizontal shelf, said shelf comprising a substantially right angular sheetof metalhaving a vertical portion provided with knucklesat its opposite ends embracing the adjacent portions of the U-shaped member, and a horizontal portion formed at its, opposite ends with tubular knuckles to embrace the end portions of arms of the aforesaid attaching means.

2, In a typewriter attachment of the class described, an attaching deviceembodying a pair of longitudinally spaced parallel suspension arms adapted to overlie the'typewriter, and a. rack including a vertical backing structure and a. horizontal shelf portion, said horizontal shelf portion having its ends formed into tubular knuckles, said knuckles embracing the forward end portions of said arms, whereby to connect said rack to said arms.

3. In a copy holder of the class described a work-supporting rack, and means for attachingv said. rack to a typewriter, Sitld. rack comprising a substantially vertical backing structure including a plurality 'of spaced parallel vertically disposed, backing slats and a substantially horizontal ledge provided with. tubular attaching knuckles. at its opposite ends, a. clamping strip attached. to the. uppermost slat, binding. nuts associated Withsaid strip for holding it frictionally against the pa per, and a pair of. spring clips mounted on the end portions of the rack, and adapted to co-operate with the clamping strip. to aidholding'the'work inplace.

4. In a work-holder of theclass described, a work'-supporti ng rack, and an attaching harness. therefor, said harness being composed ofa plurality, of wire rods fastened together, theend portions of certain of said rods being formed with terminal eyes adapted; to releasably embrace supporting feet on the base of the conventional typewriter so as to hold said harnesssecurely in place.

p 5. In a copy; holder of the-class described,

a rack, and an attaching harness therefor comprising a pair of'duplicate end members, each end member including a vertical portion provided at its bottom with an attaching eye, and a horizontal rack-supporting arm, together with a forwardly and downwardly inclined stay formed at its forward end with an eye to embrace the adjacent foot on the base of a typewriter, a tie rod conneoting the forward ends of the arms to- V gether and a shelf-forming member havin its ends connected with the forward ends the arms in front of'the rack.
