CHAI R.
SPECIFICATION forming part of Letters Patent No. 317,295, dated May 5, 1885.
Application filed December 7, 1882. Renewed October 14, 1 884. (No model.)
To all whom, it 11mg concern.-
Be it known that I, ALBERT S. CARTER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented Improvements in Chairs, of which the following is aspecification.
My invention relates to that class of chairs in which the backs will yield to the occupants; and the object of my invention is the economical construction of chairs of this c1assan object attained in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which Figures 1 and 2 are perspective views of the seat portion and back of a chai'r,illustrating my invention; Fig. 3, a side view of a part of the seat and back; Fig. 4, a vertical section of part of the chair through the hinge; and Fig. 5, a vertical section of part of the chair, showing one of the springs.
At the rear of the seat A of the chair are formed two rounded grooves or bearings, aa, separated from each other by a recess, 1), for receiving the projection d on the lower rail, 6, of the back B of the chair, this lower rail being rounded on each side of the said projection d of the back, so as to be free to vibrate in the rounded grooves a a of the seat. The back is connected to the seat of the chair by a hinge, one leaf, f, of which is let into and secured to the seat, the other leaf, f, being secured to the rounded face of the projection d, as shown in Fig. 4. Two sockets are made in the projection d of the back for the reception of portions of two springs, h h, the remaining portions of the springs being contained in sockets on, made in the edges of the seat. In order to prevent the ends of the spiral springs from penetrating the wood, I lodge a cup-like plate, at, of metal in the end of each socket m of the seat, and a similar plate, 10, in each socket in the projection d of the back.
The back of the chair will yield to the occupant by turning to a limited extent on the hinge, but will instantly recover its normal condition, owing to the action of the springs, when pressure on the back ceases.
I claim as my invention- 1. The combination of the seat chair, having a recess, 12, and sockets m, communicating therewith, the back B, hinged to the seat and having a projection, d, fitted to the recess 1), and the expansion-springs h, contained within the sockets m, and exerting an outward thrust upon the projection d of the back, as set forth.
2. The combination of the seat A of the chair, havinga recess, 12, and rounded bearinggrooves a a, with the back B, having a projection, (2, adapted to the recess and hinged to the seat, and rounded portions e, adapted to the grooves a a, and with springs h, fitted to sockets in the seat and projection, as set forth.
In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
ALBERT S. CARTER.
