Application filed July -29,
To all whomz'tmag/ concern. 7 i 7 Be it known that I, WILLIAM L. BLAIR, citizen of the United States, residing at Chicago, in the county of- Cook and'State of Illinois, have'inventedcertain new and use ful Improvements in Bookrests, of which the following is a. specification.
This invention relates to reading desks and more particularly 'to certain new and useful improvements in book-supports of the type shown and described, in my appli cation for patent, Serial No. 530,406, filed on Itis the principal object ofthelpresent' invention to provide asnnple arrangement of partsfwhich permits 01" the supporting ori leg-elements of the easel being collapsed or divided 'for'the purpose of placing the de vice in a box or package of compact -form put away in a mensions. V Y V Another object of the invention is to provide means to efiect and maintain an adjust ment of the supports of the desk in order to vary the angle at which the book rest of the same is heldbefore the eves of the reader, and still other obiects reside in certain tails of construction, all of 'whichwill be fully explained in the course of the follow ing description. l 7 H V In the accompanying drawings, in'tl various views of which like parts are simr;

Referring to the drawings, the reading desk consists of a book rest composed of a back-board 5 and a trough-like support 6 at the lower edge thereof.v The book rest is mounted in a slanting positionupon a frame composed of a pair of substantially parallel 1922. :SeriaI na s'zsesv'.

The extremities of the corresponding ends of the feet and the brackets are bent at right 7 7' angles in opposite directlo'ns,asshownin Figure 3iof the -*dra-wings, and-the'ends are rigidly connected bymeans of couplings 13 which embraceat-heir bent extremities and "are each composed-of twohol'lowed halves rigidly clamped together by'bolts l t "and "nuts 15.
