i book may be held in any one of a number of 15 positions, accordingto the desire of the user.

A further object of this invention is to provide a device of the class described in which the supporting member formsthe cover of a box, the said box serving to receive and con- 2- ceal. the supporting arm when the cover is closed, and also serving as a receptacle for the book.

It is a further object of this invention to provide a reading board having a novel form of adjustable supportingarm for maintaining the book supporting member in the desired position.

A further object of this invention is to provide a reading board which is simple in con- 39 struction, attractive in appearance, and well adapted for the purpose described.

With the above and other objects in view, the invention consists of the improved reading board, andall its parts and combinations,

as set forth in the claim and all equivalents thereof. 7

of theoover and the supporting arm extendin therethrough; and i Fig. 5 is an enlarged fragmentary sec tional view showing I the arm-engaging I bracket.

Referring to-the drawingdthenumeral 8 designates the base portion which is shown, as substantially rectangular, but which may be of any other suitable shape. The inner edge of the" base member is formed with a large recess 9. so as to provide ample room for the reader. I i

Positioned on a: central portion of the 1 board is a box 10 to one side of which a cover 11 is secured by hinges 12. The said cover is provided along its lower edge with a strip of .material 13 forminga supporting shoulder for a book. Near the'other edge ofthe cover, and secured tothe lower side thereof,

is a fastening member 14 for engaging a com- '70; I

plementary' fastening member 15 on the box to lockjthe'cover in closedposition. i Secured'to the lower surface of the cover, atoneside thereof, is an angle-bracketlfi, to the end of which, one end of a supporting arm 17 is pivotally connected as at, 18. The I said arm is slightly bent as at v19, and is formed on its outer edge with a plurality of teeth 20. Aloop-shaped member 21, also secured to the lower side of the cover, forms a The teeth on the lower portion of the arm are adapted to engage a bracket 22 secured to and extending from a side of the box.

In using the device, it is preferably positioned across the arms of a chair, as shown in Fig. 1. The cover 11 is then opened to a position similar to that shown by full lines in Fig. 3, the arm 17 sliding over the bracket 22 as the cover is being opened, and automati cally locking it many desired position. It

will be noted that in raising the cover it is,

unnecessary to touch the arm 17, as the latter is etficiently guided by the-

brackets

22 and 21, and the'teeth 20 will catch of their own ac-' cord when the hand is removed from the cover. A book may then be placed on the cover as shown'in Fig. 1, the lower edge of the book being supported by the shoulder 13; To close the cover, it is merely necessary to disengage the teeth 20 of the arm 17 from the bracket 22. When in closed position, the arm 17 fits within the box, as is shown by the dotted lines in Fig. 5, and is entirely concealed. The box 10 is of sufficient size to accommodate a book, and this convenient feature of construction makes it possible to place the book, which is being read, within the box, so that the reading board and book may be put away together, when not desired, ready to be used again at a latertigpe,

Although only one form of the invention has been shown and described, it is not desired to be limited to the particular showing, as

1 the broad concept of the invention contemp e esa medication nd qu ents hich may fairly come within the scope of the claim.

What I la m n A supporting board comprising a base member, a bo x port on on the upper surface of slaid base member, a supporting member hingedly connected to a side of said box, an arm'fpiv'otally connectedat one end" to said supporting member near the free edge of the -'latter andhaving'teeth formed on its lower edge near the other end thereof, said arm having a length nearly as great as the width of th'e box and snbstantially having its free end 31) positionable within the box portion greater thank the. depth thereof and adjacent the hin ededge of the supporting member when thifiatteris down, a bracket on an inner side ofr said'lb o x on which the lower edge of said arinj're'sts, said arm being movable with the supporting member when the latter is raised, the "lower edge of the arm sliding over the bracket, and the teeth being engageable with the bracket to hold the supporting member i Jalny adjusted-position, and aloop-shaped member extending from thesupporting memher and surrounding said arm to preventout- Weird. .ii v 'men here f b ymd e m s f the'bozr, i v' testimony whereof I affix my signature.
