PATENT OFFICE.

GEORGE BUCHANAN, OF WASHINGTON, PENNSYLVANIA.

IMPROVEMENT IN RECLlNlNG-CHAIRS.

specification forming part 0f Letters Patent No. 141,318, dated July v29, 1873; application med June 28, 1873.

To all whom it may concern: f

Be it known that I, GEORGE BUCHANAN, of Washington, in the county of Washington and in the State of Pennsylvania, have iuvented certain new and useful Improvements in Adjustable Chair; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of an adjustable chair with hinged arm-rests, as will be hereinafter more fully set forth.

- In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a .side view, and Fig. 2 a vertical section, of my chair.

A A represent the front, and B B the back, legs of a chair-frame, connected and braced by suitable rounds. The legsAB are extended upward above the seat sufficiently to form supports for the arm-rests C C. These rests are hinged to the upper ends of the back legs B B in such a manner that they can bethrown up and rest upon the upper ends of said legs. The front ends of the arm-rests C G,when down, rest upon shoulders or offsets a d formed on the rear side, at the upper ends, of the front legs A A and in the front end of each rest C is inserted a spring-bolt, b, beveled on its outer end, and springing into horizontal holes made in the upper ends of the front legs, to hold the rests down in proper position when the chair is used as an ordinary arm-chair. In the hole mentioned in the upper end of each front leg A is inserted a bolt or pin, d, which is forced forward to project slightly beyoud the front side of the leg when the spring bolt b has entered the rear end of said hole. By pressing inward on the projecting end of the pin d the spring-bolt b is forced inward sufficiently to allow ofthe arm-rest being raised or turned on its hinge. At or near the inner end of each arm-rest C is attached a metal bar, f, with projection e,- and between said projections the seat-backD is pivoted, by screws, pins, or their equivalents, passing through the projections into the edges 0f the back. The side pieces of the back D project a short distance below the main part of the same; and between the lower ends of said sidepieces the rear end of the seat G is pivoted. The front end of the seat rests upon a round, h, connecting the two front legs A A. On the under side of the seat G are two halfround bars, t' t', and a staple, k, to form stops, in connection with the round It, to hold the seat in various positions.

When the arm-rests C G are down the chair Y may be used as an ordinary arm chair; and the seat may be adjustedv forward or' backward, as desired.

By partially raising the rests C C the arms of the person occupying the chair may be supported in proper position to hold a heavy book 5 and, by raising the armrests to a perpendicular position, the shoulders of the occupant of the chair are thrown back, and the chest eX- panded. The seat is then adjusted to form a reclining-chair or a readingchair.

It will readily be seen that the 'position of the arm-rests is changed and the seat adjusted by the person sitting on the chair shifting his weight to eifect the changes.

Having thus fully ldescribed my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. The combination, with the chair-frame A B, ofthe hinged arm-rests C C, p-ivoted back lD, and pivoted seat G, the front end of the seat being supported on the round h, all as herein set forth.

2. The spring-bolt b in the front end of the arm-rest C, in combination with the movable pin or bolt d in the leg A, for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of June, 187 3.

GEORGE BUCHANAN. Witnesses:

HENRY M. DOUGAN, JOHN W. SEAMAN, Jr.
