`This invention relates to improvements in paper and book supports and pertains -particularly to an improved copy stand designed particularly for the use of typists. 5, The primary object of the present invention is to provide a copy stand which is foldable and which may be readily adjusted for height and for width to support sheets or books at the proper angle for copying.

Another object of the invention is to provide a copy stand' which in addition to being adjustable as a whole to increase or decrease its width, has as a part thereof book or sheetA supporting elements which may be adjusted relative to one another transversely of the stand structure. j

A still further object of the invention is to provide a novel type of copy stand which may be applied to a disappearing type of typewriter so that thestand may be shifted with the typewriter when the portion of the typewriter desk structure ,upon which the latter is mounted is shifted to close the desk and to cover the typewriter.

Still another object of the invention is to provide a copy stand having several minor novel features of construction whereby the stand is made more serviceable and better adapted to perform the several functions for which it is designed.

rEhe invention will be best understood from a consideration of the following detailed description taken kin connection with the accompanying drawings forming partnof this specication, with the understanding, however, that the invention is not coniined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a view in front elevation of the stand embodying the present invention.

Figure 2 is a view in top plan of the same.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is an enlarged detailed section of the connection between a leg and the stand.

f Figure 5 is a view in plank ofaportion of ay typewriter desk showing a method of securing thestand thereto.

Referring more particularly tothe drawj ings wherein like numerals of reference in- 5 dicate .corresponding parts throughout the several views, it will be seen that the copy stand embodying the present invention comn prisestwo main portions, that is the base 1 and the back 2 each of which is in the form 1 of arectangular frame. The base 1 consists of the flat side bars 3 normallydisposed in parallel relation and eachjhaving at its forward end and pivotally attached thereto as .at t by a rivet or other suitable means a longitudinally slotte-d link 5, the two links 5 being adapted to be swung to a position where their free ends may be'brought into overlapping relation to receive a removable securing element 6 thus' converting the links 5 into a front bar for the base. l

The back 2 is made up of the upright side bars 7 each of which is divided linto two porv tions, each of which portions has a longitudi- `nally extending slot 8 therein, the overlapping 4end of one of the portions carryinga pin 9v which slidably engages Yin the slot of the adjacent portion while the end of the i said adjacent portion carries la thumb screw 10 which passes through the slot of the other portion and when manipulated 4serves to tighten the connection between thetwo portions 7 so thatl they will be held in any dei sired adjusted position. The lower end of 35 each bar 7 has hinge connection as at 11 with the rear end of the adjacent'base bar 3, this connection being such that the back may be swung forwardly and face down onto theA base when the vstand is folded.

Connecting' the lower ends of the bars 71is a transverse two part bar 12 each of the parts being indicated by the numeral 12a and each having formed therethrough a longitudinally extending slot 13. The adjacent ends of the 95 portions 12a of the bar l2 are arranged in overlapping relation and are slidably connected by thumb nut and screw 15`the screw p assing through the slots of the bars. Atthe upper ends of the bars 7 a crossconnecting 100 top bar 16 is positioned, this top bar also being in two portions and constructed 1n eX- actly the same manner as the bottom bar 12, the ends of the top bar 16 being riveted as at 17 to the adjacent side bars 7.

Intermediate the ends of the side bars 7 there is positioned an intermediate transverse bar which is indicated generally by the numeral 18. This bar 18 is in two portions, each of which is slotted, and these are in end overlapping relation and have a thumb screw 18 extending therethrough to retain them together. At its outer ends the transverse bar 18 is traversed byv the thumb .screws .10 which connect the two portions of the side bars '7 together. A pair of legs 19 is provided for the support of thel back 2 each of which legs is made in two portions, the overlapping ends of which are held in sliding engagement by a thumb screw 20 which vis carried by one portion and works in a longitudinal slot in the lother portion, the said other portion ycarrying a pin which works in a longitudinal slot formed in the portion which carries the thu-mb screw. The construction of the legs in this respect is the same as the side bars and the cross connecting bars of the back.

The outer Vend of one portion of each leg `19 :is bent to extend at an angle therefrom as indicated at 21, this angled portion .of each leg constituting the top of the leg and hav-ing iin the face thereof a headed stud 22 which has had 4opposite sides -thereof cut away as indicated at 23. These legs are kcon- .nected to the back by positioning them rlon- Iitudinally of the bar 16 so as to permit the .insertion 'of the head of the stud 22 into the slot of -one of the portions ofthe bar 16 after which the leg .is turned 4to a position wherelit extends transversely of .the .attached bar. With the .angled portion 21 of each leg posi- -tioned against the attached bar 16 Vthe leg will extend therefrom `at such an angle that .the back 2 will be maintained in a .rearwardly .inclined position. y

Arranged to `extend .across the forward faces of the bars 16 and V18 is a pair of supporting bars 24 each of which has its upper end turned `to Lform a hook .25 which engages `over the -top -bar .16. Each of `these supporting bars 24 is .longitudinally slotted as indicated Vat 24a to receive -'the shank of 4a support hook 26. The shanks of these hooks 26 are threaded as shown and -carry .a pair lof Vvnuts .27 which are disposed upon opposite facesof the 'bars124-through which .the shanks pass. For all ordinary 'occasions 'the shanks may also -be extended through the slots .formed in the gportions of the intermediate transverse bar 18 .so that any tendency on the part of `the suppor'ting hars 24 lto .oscil- -late will be prevented.

Each pontionofethe top bar 16 .hasa'djustably `attached thereto the turned kend n28 of a spring arm 29, the connection between the portion 28 of each arm and the adjacent portion of the bar 16 being by means of a screw and thumb nut 30 by means of which the spring arm may be secured in any desired adjusted position on the bar 16.

A leaf holder extends across the face of the back 2.at the upper portion thereof and comprises a pair of hooks each of which is indicated by the numeral 31 which engages over the outer edge of a side bar 7, and a connecting cord 32 between the hooks having interposed therein one or more springs 33. It will befseen that the springs 33 tend to maintain the cord 32 taut toward the front ot the rest back so that when a book or leaf is rested upon the two hooks 26 this cord may be placedv over the same and will thus maintain the leaves of the book or the sheet in the proper position.

In Figure 5 I have illustrated the manner in which the copv or book stand may Vbe attached to the shiftable top portion of atypewriter desk to which .a typewriter is ordinarily secured. This shiftable portion of a typewriter desk is indicated generally by the .numeral 34 and as is well known is usually mounted upon pivot arms so that when it is shifted by the opening `or closing of the typewriter Vdesk the typewriter carried therehv will be brouOht into view or covered r desired. As is also well known these shiftable portions-of typewriter desks carry a sliding panel 35 upon which a typewriter is mounted and metal `cleats 36 are usually attached to the portion 34 and overlying the panel 35 to maintain the latter in sliding engagement with the portion 34.

By removing the Vthumb screw 6 which connect-sthetwoportions5,5 making up the front bar vof the stand base, and swinging these portions ou-t to a position'where they are in :alignment with the sides 3, the sides 3 and the portions of the front .cross bar may be slipped beneath the guides .36 after the holding screws therefor have been loosened and Vupon .retightening these .screws after slipping the elements 3 .and 5 therebeneath it will be Yread-ily seen that these parts of the Ystand ibase will be iirmly secured in pla-ce s0 .sup-ported thereby. When the book or sheet .is in position upon the stand the cord 32 may be extended across the facethereof and in order to furtherfmaintainthe leaves of the book .or-the sheet in the proper ,position the yspring arms 2.9 may be swung around to a position where they are substantially parallel with the sides of the stand back and overlying the sheet or body upon the stand.
