Referring to thefdra'wings inv detail,.and

wherein similar reference` characters 'designate corresponding parts throughout the several views,'the letter A may designate a suit.- able support member, B an 'adjustable sup-l vporting structure for detacliableconnection cirwithtlie support A, and Cy a holder` proper *i carried by the free f end of kthe supporting structure Y v In the illustratiomthe support member ,A pretcrably constitutes oneof the side V'frame members of a typewriting machine. V i

' AThe adjustable supporting structure efmf' bodiesjan attachingclamp 10, a longitudinally adjustable swing beam 11, and a; vertically adjustable stand. arm 12 disposed at the ,outer or free end of the swing beam.11. The attaching clamp 1Q embodies a -U-sliap'edibody portion providing spaced inner and outer clamp plates 18 andy 14 respectively, which when the U-shapedbody is slid upwardly from beneath the frame member A, are adapted to extend'one ateach side o1v the'iframe member. Threaded V.into the outer clamp plate 14, is a wing nut 15lhaving ahead 16 swivelled upon its inneiendfor clamping' enV- gagenieiit with lthe member Afoi rigidly se* curing the supporting struct'urezto,.the'supe portingr member. `Extending*outwardly at a right angley from the upper end of the clamp plate y14C', is a horizontallydisposed wing 17` and which wing rigidlysupports ,at its fup-v per side, a vertically extending stud 18 having a screw threaded upperend for threaded reception of a wing nut 19. This stu'df18 may be secured in the wing 17in any suit-r able mannei, and a washer `2() is preferably disposed. about-thestud at the upper face of' the wing.l Y n ,i

rhe swing beam V11 which is preferably.

formed fromk telescopin'g tubular sections,

embodiesan outer tubular section 21 and an inner tubular section 22 of a diameter to sniigf ly yand frictionally slide `within the tubular i section 21. The tubularsecti'on 21 isfpro, v Y

vided adjacent its rear end with aligned apertures23 for receiving thestud 18 ofthe attaching clamp 10. This mounting of the tube section 2l upon thefjstud 18 allowsl for horizontal swinging of tlieswing beam 11, andv upon tightening of the Wingnut 19 upon the any adjusted liori'zfontalposition. Pro.-

` tube section 21, the swing beam may beheld 1.1.0

vided in the under side of the tube section 21,

andterminating short of the ends thereof, is

a longitudinally extending slot or guideway 24 through which a set screw 25 may pass for threaded engagement with the inner end of the tube section 22 as clearly illustrated in Figure 2. Thisslot 24 and set screw 25 will allow for longitudinal adjustment of tpeY tu e swing beam without allowing for the sections 21 and 22 becoming separated. The

slot 24 and set 'screw 25 also prevents rotaryv movement v`of the sections 21 and 22one within the other, and which relativev rotary movement of the sections would be undesirable as v:will be later explained. Provided in the outer end of the tube lsections 21, are'aligned screw threaded bores 26 the axis of which extends in parallel relation'with the axis of thealigned apertures 23, and the purpose of 'which screw threaded bores will be subsey parallelwith the'axis of the stud 18.. A vsuitable plug or closure cap 28 may be employed forclosing the outer endofthe tube section 22. Referring now to the stand arm 12, the

same embodies a threaded shank portion 30 y which is intended to be threaded into the aligned'threadedjbores 27 of the tube section 22, and from the upper end of which shank portion, forked arms 31 extend. upwardly for hinged connection with the holder proper C. `It will be seen that upon rotation of the stand arm, that the same will, through its y threaded'connection withthe tube section 22,

be raised and lowered for vertical adjustment of the'holde'r proper, and that upon proper vso nut, 32k which is threaded upon the shank beneath the tube section,-may be turned into binding engagement with the tube section for preventing further vrotation of the stand arm. It may here be mentioned that by so prevent- Ving relative rotation of the tube sections, as .by means of theslot 24` and set screw 25, that the stand arms 12 will'be retained in kavertical upright position forV proper supporting of the holder proper C. Y

Referring now to the holder proper C, the same embodies a substantially lrectangular shaped rest plate 35 which may be formed either of wood or sheet metal, and from the central lower portion yof which a thumb'engaging lip v36 extends. Secured longitudinally at the rear face of the rest plate, and4 centrally thereof, is an attaching plate 37 having rearwardly extending spaced apart ears 3S-and 39 provided respectively at the upperV and lowerjends of the vplate.` These ears j38 and 39 are preferably Vformed by bending up the end portions of the attaching plates. Pivotally mounted intermediateits ends between the upperspacedV lower arm portion 43 which is of U-shape in cross section, extending Vdownwardly from the hinge pin in diverging relation to the rest plate. i Secured in the upper end of the tubular arm portion`42,'is`ajclamp vrar1n144 which extends forwardly through'a notchorr recess 45 provided in the upper marginal edge of the rest plate, and having providedat its forward end a depending hook portion '46 which Yoverlies the upper portion oftheface ofthe restv plate 35, A spring 47 coiled about the hinge pin l40,'has one freeend thereof bearing against lthe vrea-r face' `oftherest plate, and its op'pe'site freeendfextending up` lw'vardly in the tubular arm' portion 42 for normally urging the arm 42 rearwardly and the hook portion 46 toward-the frontface ofthe rest plate. VPivotally mounted intermediate its ends between the lower spaced'fears 39 as by a suitable hinge pin 48', and extending in alignmentwith the, clamping ylever 41, is a re-r leasing leverV 50 having-its'upper arm portion 51 engaging the inner side of thelower arm portion 43 ofthe clamping lever 41, and having its'vlower arm 'portion 52 which extends in downwardly diverging relation to the rest plate, terminating at a point directly to ther rear ofthelip o'offth'e rest structure. By so 'having the lower arm43 of the clamping lever 41, ofi U-shape iny cross section, the same forms a the upper end of the arm portion 51.

The upper ends ofthe forked arms 31 are provided withl oppositely extending pintles l l h i 54 which are mounted in friction hinge Aclips vertical adjustment of the holder, the wing 55 secured to the rear face of the rest plates to each side of the attaching` plate/37. lThese hinge clips 55 are preferably made of'spring material so thatfsuificient` friction will Vbe sgi.

pocket 53 for receiving y A section 21, and the wing nut 32 threaded' upon arm in adjustedposition. This construction will be found extremely advantageous when applying the supporting structure to a support so positioned las to prevent utilizing of the entire swing beam.

In positioning la notebook or f copysheet upon the holder 'proper, the'operator 'first places the thumb against the lip andgrasps f the lower end thereof vfor locking the ,stand with his forefinger, the lower fiatv portion 60 of the releasing lever 50. By drawing his foreinger forwardly, the upper arml section 51 swings outwardly about the hinge pin 48, forcing the arm section 43 rearwardly and the upper arm portion 42 forwardly thus causing the clamping arm 42 tov move for# wardly and carry the depending hook portion 46 out of engagement with the frontfa'ce of the rest` plate. During this forward swinging of the clamp arm44, the notch 45 serves as a guide for preventing any rlateral movement of the arm. After positioning' the upper end of a notebook or copysheet beneath the hook portion 46, the lever 50 may be released and through actionV ofthe spring 47, the lever 41 will assume its normal position and draw the hook 46 into vclamping engagement'with'the article to be held upon the rest plate.

Concerning the various positions the holder proper may assume withl respect to the support A, the same may be swung toward and' away fromthe support in a horizontal plane about the stud 18, may be shifted toward and away from the support by reason of the telescopic tube sections 21 and 22, may be adjusted vertically'by means of the'stand arm 12, andy may be tilted at various angles by means of the hinge means 54 and 55.

From the foregoing description it will be apparent that an 'extremely novel` and efficient copy holder has been provided embodying features wherein the holder proper may i kbe adjustablydisposed in a position to permit of copies held thereby to be readily observed without straining of ones eyes while tran- I scribing the copy supported in the holder.
