IMPROVEMENT IN DESKS AND BOOK-CASES.
Specification forming part of Letters Patent No. 139,419, dated May 27, 1873; application filed May 3, 1873.
' the letters and figures of reference marked thereon.
Figure l of the drawings is a representation of a vertical section of my combination desk. Fig. 2 is a horizontal section of the same. Fig. 3 is a side elevation of the same.
My invention relates to desks and it consists in the construction and novel arrangement of a writing-desk, a revolving reading desk, and a revolving book-case, mounted on an upright pivot and on a horizontal frame or plate which rest on vertical racks with gear-wheels, by which the desks and bookcase may be elevated or lowered at pleasure. The object of my invention is to furnish a piece of furniture which combines the con veniences of thethree above-mentioned articles in such proximity that a person may make use of either desk and the book-case without changing his position, and that he also may be able to change the elevation so as to suit him, in any attitude he may choose for writing or reading. The advantages of my invention maybe enhanced by the application of an adjustable chandelier to the same upright pivot around which the desk and book-case revolve.
In the drawings,A A A A represent the legs of a table, which may be braced near the lower ends by the braces B and which are braced above by diagonal braces O O and an octagonal or round rim D. Below the said rim are fastened the bearmgs E E, which support the shafts F F F F, one of which is provided with a hand-crank, f. At the end of each shaft is a bevel-gear, G, gearing into a central bevel-gear, H, which turns on an upright pin or tube, I, and serves to communicate motion from one shaft to the remaining three shafts. The shafts F F F F are prois a combination of several inclined plates connected on top with ahorizontal plate, 0,
through which the tube 1? passes, and another plate or frame, o,which connects the lower parts of the desk-plates .O O, and is also pivoted to the tube P. The writing-desk is fastened to the tube]? between theplate o and the frame 0, and is accessible through the reading-desk by swinging two hinged inclined desk-doors open. The book-case Q revolves on a'tube, R, fastened in the tube P, and travels onthe top-plate o of the reading-desk O. The tube 1?. extends above'the book-case and carries an arm, S, with a burner or chandelier for the application of gaslight. To avoid inconvenience in turning the book-case when it is heavily loaded with books, the bottom of the book-case should be provided with friction-rollers q q. Frictionrollers should i also be fastened to the bottom of the reading-desk O to travel on'the frame M of two witnesses.
