IRA L. HYDE, OF OLAREMONT, VIRGINIA.
SPECIFICATION forming an: of Letters Patent No. 314,181,
dated March 1'7, 1885.
Application filed June 17, 1884. (No model.)
. To all whom it may concern:
1 and other articles.
Be it known that I, IRA L. HYDE, a citizen of the United States, residing at Claremont, in the county of Surry and State of Virginia, haveinvented certain new and useful Improvements in Book-Supports, of which the i'ollovw ing is aspecification, reference being had therein to the accompanying drawings.
This invention relates to certain improve ments in detachable and adjustable reading and writing tables for chairs and other articles of furniture; and it consists in the novel construction and arrangement of the parts, as more fully hereinafter described, and speciir cally pointed out in the claim.
In the accompanying drawings,Figure 1 represents a perspective view of my invention.
Fig. 2 represents detached perspective views of a portion thereof. Fig. 3 represents a ver tical sectional view of the desk and connections; and Fig. 4 a detailed view of the adjusting devices.
The letter A indicates the desk proper, which consists of a flat board or tablet, curved out at one side, so as to fit against the body of the occupant of the chair and form a rest for the arm. The said board at convenient intervals is provided with a series of apertures, B, for the reception of the pins of an adjustable bookrest, O,'.which is employed when. the. table is used in an inclined position. The board or table near the upper end is provided with an elastic cord, D, which may be placed over the upper margin of the book to hold it open and keep the leaves in place. Beneath the board is a drawer for ink, pencils, stationery,
To the under side of the board is secured a metallic quadrant or bracket, E, which has a curved slot, F, and an open slot, G, near its upper end. The said quadrant or bracket is provided with a lug or stud, H, which forms the center of a circle of which the curved slot is an arc.
The letter I indicates an upright or standard, which is flattened at its upper end, and
is formed with a half-circular hearing which engages the lug or projection in such manner as to let the table swing freely. The said standard is provided with a binding-screw, K,which sets through the curved slot and serves to bind the parts together to hold the table in an adjusted position.
The letter L indicates a hollow standard,
which has a jaw, M, at its lower end, which may be fitted over the arm of a chair, and g M a set-screw, by means of which it may be clamped in place. The said standard near its upper end is formed with a slot, N, on one side and with an aperture, P, directly opposite i'or the reception of acollar, P, having a 1ongitudinally-screwthreaded shank, B, upon which is a binding-nut, S; The standard I passes down through this collar and by it is adjusted at any desired elevation, as by loosening the nut the standard may be moved vertic-ally, and by tightening it the standard is firmly clamped.
It will be seen that bythe construction of the slotted quadrant thedesk or table can be readily placed upon or removed from the standard without removing the set-screw, which is a great convenience and prevents the loss of the set-screw.
Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-
The combination, with the board or tablet A, provided with the quadrant E, having curved slot F, an intersecting radial slot, G, and a lug or stud, H, of the standard having its upper flattened portion provided with a semicircular bearing to fit the stud H, and a bindingscrew, K,the whole constructed and arranged snbstantiallyas shown and described In testimony whereof I my signature in presence of two witnesses.
