ooPY-HoL-ome ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 740,520, dated October 6, 1903. Application filed June 1, 1903. Serial No. 169,476. (No model.)

copy-holding attachment for type-writing machines, the invention having for its more prominent objects compactness as well as adaptability for application to various styles andconstruction of machines and also capaf hbilit-y for-holding the copyin a convenient position immediately at the rear of the paper f roller or platen.

Facility for adjusting the positio'n of the copy-supporting frame is also an object;

With the above and other purposes in view the improved attachment comprises a novel arrangement including a clamp for taking over and being secured to the rear portion of them'achine-base, a light standard supportto by said clamp and having a curve'dupper portion for overhanging the upper rear part of -the machine and carrying a copy-frame provided with copy-retaining provision, preferably of spring ch'aracter, the upper curved 'portion' of the standard being extensibly adjustable for the purpose ofraising and lower-..

ing as well as advancing or moving rearward the copy-frame to limited extents. There are other important features connected with the invention which, as well as those alluded to, are clearly set forth in the subsequent detailed description.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevational view of sufiicient portion of a type writing machine to illustrate the application of my invention, a portion of the base rear being sectioned to indicate the means by which theimproved copy-holder is attached to the machine and a portion of the standard being broken away. Fig. 2 is a front detail view of the clamp by which the attachment is secured to the machine. Figs. 3 and 4 are detailed views.

different lengths.

- A refers to the base of a type-writing machine, which in most constructions embodies I the back a and horizontal cross-piece a, ex-

tending inwardly at the top of the back and transversely disposed, said cross-piece being provided at its inner edge with a depending flange a The medium by which the attachment is :secured to the machine is presented by a clamp B, comprising the short longitudinal bar or plate b,'having its respective end portions 17' b bent downward, as indicated in Fig. 1, the plate-b being placed to rest upon the cross-piece a with its portion b bearing against the rear wall a, said plate being secu rely held in such position by a thumb-screw b mounted in the portion b and manipulated so that its free end bears against said portion 5 thereby securely clamping the plate I) on the machine. Rigidly carried by the clamp thus formed is a light standard C, which is of such height that its forwardly-curved upper bend o amply clears the upper part of the machine, particularly the customary paper rest D. 1 preferably provide the bend c -with a separate section 0 of corresponding breadth and thickness and shaped to approximately form a continuation of the curve partly presented by the bend c. This section 0 is ciamped to the bend 0 so as to be in extensible relation therewith, this clamping being efieoted by a sleeve E, configurated to closely embrace overlapping portions of'the bend c and section a and positively hold the same together by means of a thumb-screw e bearing in the top of the sleeve and coasting with the bottom part of the sleeve to clamp the bend and section together. The forward end of the section 0 has firmly connected thereto thecentral part of the lower horizon tal bar f of the copy-holding frame F, the lat terbeing supported in the slightly-oblique position indicated in Fig. 1 for, convenience in retaining and observing the copy thereon. This frame F will also'be desirably extensible, so as to adapt it for holding sheetsof copy of To. provide for this, the frame is disclosed as comprising lower and upper sections F F which for the sake of light- .ness and simplicityof construction are'of wardly-inclined side bars f f and intermediately-located transverse bar f The section F is composed of the upper cross-bar f and downwardly-extending forwardly-inclining side bars J, the latter slidingly bearing against the outer faces of the bars f of the lower section. Longitudinal slots f in the bars f permit the passage of threaded pins f laterally projecting from the bars f, near the upperends thereof, thumb-nutsf", engaging the pins, acting to hold the section F in any position in which it may be adjusted relative to the lower section. To prevent any turning movement of the section F on the fulcrums constituted by the pins and also insure the positive guiding movements of the frame during the adjusting of the same, the ends of the bars f below the pins f are provided with front and rear inwardly-projecting earsf which overlie the edges of the bars f, and thereby attain the ends sought.

From the foregoing description it will be appreciated that a copy-holder embodying my invention is not only simple, neat, durable, and comparatively inexpensive, but is of such character that it can be readily attached to most, if not all, of the existing constructions of machines and when so applied will maintain the copy directly in front of the operator and in a manner in no way calculated to interfere with the operation of the machine.

- With a View of avoiding any scarring or defacement of the surface of the machine-base I may provide the portions b" b of the clamp with pads or cushions b of yielding material, such as felt, moderated hard rubber, or other similar substance. By making the plate I) and its portions 1) b of thin sheet-steel the edge portions of the bends can be turned over to embrace the pads in a manner to leave sufficient of the latter protruding to provide the required cushion-surface. This feature of the invention is most clearly illustrated in Fig. 3. important functions, as it not only constitutes an internal brace for both sections composing the frame, but will serve as a rest to cooperate with the contiguous portions of the side bars in holding sheets of reduced length, such as letter and corresponding sizes, without requiring any special adjustment of the section F for this purpose.

At the bottom of the section F is a pivoted spring-clip G, adapted to be manipulated by the operator to clamp the lower edge portions of the sheets of copy. Manifestly, as the fore- The transverse cross-bar f performs.

reserve the right to all modifications that may be fairly within the scope of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A copy-holding attachment for typewriting machines comprisinga rear clamp, a standard rigidly carried thereby, and having an upper forwardly-overhanging section, a copy-frame supported by said section and embodyinglower and upper parts, the lower part formed by a bottom cross-bar, transverse and rearwardly-incliued side bars, the latter having lateral threaded pins near their upper ends, and the upper part embodying top crossbar, and forwardlyinclined side bars, said side bars sliding by bearing against the corresponding bars of the other part, and having slots through which the pins project, and nuts for said pins.

2. A copyholding attachment for typewriting machines comprising a rear clamp, a

standard rigidly carried thereby, and having an upper forwardlyoverhanging section, a copy-frame supported by said section,and embodying the upper and lower skeleton parts including the transverse bar f and side bars f, f in sliding contacting relation, the end of one of the side bars of each pair having ears engaging its companion to prevent turning and for'guiding the bars in their sliding movements, and means for adjustably clamping said side bars together.

3. A copyholding attachment for typewriting machines com prisinga rear clamp embodying the plate I), with angular bonds 1), b yielding pads for said bends, a clampingscrew for one of the latter, a standard rigidly supported by the rear clamp, and having a forwardly-overhanging upper section, a copyholder carried by said section and composed of the relatively extensible sections F, F
