BOOK-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 249,216, dated November 8, 1881.

i Application filed September 30, 1581. (Model.) i

' the invention, such as will enable others skilled in the art to which it a'ppertains to make and use the same, reference being had to the accompanyingdrawings,and to letters or figures of reference marked thereon, which form a part of this specification. p

Figure l is a front view ot' my book-support in open condition. Fig. 2 is a detail ot" the same; and Fig. V3 is a perspective, showing more fully the details ofv construction and a modilcation of the location of thefastenin g device and a base of reduced area.

Like letters ot' reference refer to like parts in all the figures.

My invention relates to that class of booksupports in which the book is inclosed in a case adapted to open and serve as a support of the book in a position to be readily accessibie, and which are mainlyintended for dictionaries and other cumbersome books ot' reference.

Referring to the drawings, A represents the case which incloses and supports the book, and it consists of a bottom, a, two sides, b, (one of which only is shown,) a cover or lid, c, and four end cleats, d. The end cleats are secured to the ends of the sides, and at their lower ends are pivctally attached to the bottom a, thus forming a hinged connection of the sides and bottom. In this instance I have shown the sides less in depth than the book which they areintended to` iuclose; but, if desired, they may extend and befattached by means of ordinary hinges at their lower edge to the bottom a, in which case the pivotal attachment of the cleats d at ewouldbe dispensed with. r.lhelid lis hinged tothe upper edge of one ofthe sides at f, and is secured ina closed condition by means of a hook and eye at g. The case is supported by four standards, h, the upper ends of which are pivotally attached to the case in mortises at fl, and the lower ends of which are provided with.outwardly-projecting shoulders k', and are pivotallyattached or seated in thebasedition by being pushed one side by spring a thereto attached, and embracing the baseboard, the notch receiving the same and retaining it until released by pressure applied in opposition to that of the spring; or a springpushed bar, o, (see Figs. l and 2.,) may be located beneath the base-board and pass through anaperture in the central post, C, of the book! support and enter the notch m of rod l, which, in this case, is secured at the center of the bottom a, post Obeing adapted to receive it, and an additional notch, m, may be provided to secure the case in a closed position. The spring in this form and arrangement of the parts may also be coiled about the rodo, as shown. The post C is provided with suitable feet, D.

The operation of my book-support is as follows: Taking it in a closed position, the hook g is` unfastened, the lid opened, and pressure is applied as in opening the book, when the bottom rises, and the standards, moving on their pivots in the base-board, assume a perpendicular position, where they are`retained by their outwardly-projecting shoulders comingin contact with the upper surface of the base-board, thus rendering the support, when open, strong against lateral pressure, and in the meantime the sides have moved upon the pivots at the upper ends of the standards and have assumed a horizontal position, and the fastening-rod has been lifted by the bottom until its notch has received the base-board or the spring-pushed rod and the support is locked in open position; The virtual reversal of these movements closes thecase. The cleats dserve in both positions to retain the book upon and within the case. The rod 0,Fig.1,may be dispensed with, if desired.

The sides of the case and its lid may be in open or fancy scroll or inlaid work, and may be backed with textile material of fanciful colors, and the baseboard may be extended to form a table or shelf for the support of additional 2 esmero books,orit1nay be limited to an extent in area sufficient for the standards of the case to be received and operated therein.

Having described my invention and it's 0peration, what I claim as new, and desire to secure b v Letters Patent, isy l. The combination of a case, substantially as shown and described, with pivotallyattached standards provided with outwardly-extending shoulders, and a base-board provided with slots, in which said standards are pivotally secured, substantialllyT as shown and described. f

2. The combination of a case, substantially as shown and described, pivotally-attached standards, a slotted base-board, and a depending notched fastening-rod, substantially as shown and described.

3. In a book-support, the combination of a base-board provided with a central post and suitable feet, and provided with pivotal shouldered standards1 with a case consisting of mortised sides pivotally attached to a bottom by means of end cleats, and a hinged cover, substantially as shown and described.

4. In a book-support, the case A, comprising the sides b, cleats d, pivotally attached to the bott-om a, and rigid depending notched fastening-rod Z, attached to saidbottom, in combination with pivotal standards and a baseboard adapted to receive said rod and standards, and also to serve as a table or bookshelf, substantially as shown and described.

In testimony whereof I have affixed my sig-- nature in presence of two witnesses.
