Specification of Letters Patent No. 32,069, dated April 16, 1861.

To all whom it may concern:

Be it known that I, AN'rHoNrv LAMB, of Cambridge, Massachusetts, have invented certain new and useful Improvements in Bookcases; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure 1 is afront view, Fig. 2 a side elevation and Fig. 3 a plan View.

The nature of my invention consists in constructing a book case in the manner hereinafter set forth, and is designed more particularly for authors, translators and others whose occupations require a frequent reference to books. The inconvenience attending the ordinary case is sorely felt by individuals engaged in either' of the above employments, and it is to remedy this objection and facilitate the labors of these persons that I will now describe the construction of a book case which I have found of great practical utility and convenience.

(A) represents a circular platform or table which is provided on its under side with screw (cl).

(B) re )resents the legs set in the bracing position s iown in the drawings.

(e) is a cap secured on the top of legs (B B). Through the center of this cap is cut a screw thread, through which screw (d) extends, thus making an arrangement precisely similar in appearance and operation to the common revolving desk chair.

(C C) are two uprights secured on plat form or table (A) as fully seen in Figs. (1) and Upon these uprights is fastened a flatpiece or top (60) shown in Fig. (2). Upon this top is secured other u prights similar to those below, which in their turn are 4provided with a top. Then lastly two more uprights (f f) which have likewise 'a stories. a

. (D) represents a hinged leaf supported by means of the hinged braces o).

(E E E) are three shelves. Said shelves should be of equal height from the table as leaf (D), and their back placed at an agreeable angle to read, when a book is resting against them.

(z z.) are two slides on each side of leaf (D) for holding a light, ink, pens, &c.

(F), represents a hinged door opening into an apartment appropriate for papers, documents, &c.

Thus it will be seen that the student can open his books of reference and place them upon shelves (E E E), also in the various apartments, and while sitting at the leaf (D) writing, may easily refer to any book he wishes without the trouble and inconvenience of arising from his seat.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is,

The within described revolving book case, when the several parts are arranged and constructed in the manner and for the purpose set forth.
