UNITED STATES PATENT OFFICE.
WILLIAM H. PAULDING, OF NEYV YORK, N. Y.
SPECIFICATION forming part of Letters Patent No. 272,579, dated February 20, 1853.
Application filed December 20, 1882.
.To all whom it may concern Be it known that 1, WILLIAM H. PAULD- ING, of New York, in the count-y of New York and State of New York, have invented certain new and useful Improvements in Chairs ;.and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in whicht Figure l is a perspective view of a portion of the back of my improved chair, the covering being cut away to showlhe pivotedinside back frame. Fig. 2 is a vertical sectional view of the chair back and seat, and Fig. 3is a detail view ofthe adjustable back-frame with the springs removed.
Like letters ofrel'erenceindicate corresponding parts in all the figures.
While my invention relates, broadly, to upholstered chairs or easy-chairs, it is designed more particularly to be applied to railwaychairs, or the individual chairs used in so called drawing-room cars, and it is a chair of this description that I have used as an illustration of the nature of my invention. This consists in the construction and arrangement of a pivoted frame adapted to adjust itself within the upholstered back to conform to the position of the person occupying the chair, substantially as hereinafter more fully described and claimed.
In the accompanying drawings, the letterA denotes the frame, and O the seat, of my improved railway arm-chair, which I prefer to construct with a roll or head-rest, B, at the top of the frame. v
E F is the covering of the back, which may be of any suitable material, according to the style or grade of chair it is desired to make; but in Fig. l of the drawings the back part of this covering E has been removed to show the self-adjustable frame G, which is pivoted on spindles H H, fixed in the sides of frame A. This frame, it willbe seen, consistsof a lower broad part composed of two slats or crosspieces, I I, curved to conform to the shape of the back, and an upper reduced part, J, the
I sides K K of which are bent inwardly, so as to cause the upper part, J, of the frame to bear against the upper part of the upholstered front F, about in a line with the shoulders of the occupant of the chair. The lower part. or that part of the adjustable frame which is below the spindles or fulcrum-pins H H, has helical springs L, fastened to its cross bars or slats I l, which bear against the lower part of the upholstered front F, thus forming by the tension or pressure of the springs the bulge or swelled portion Eat the lower end of the back, about in a line with the small of the back of the person occupying the chair.
The adjustable frame G, with its two rows 6 of'springs, is concealed by the chair-frame and front and back coverings, F and E.
From the foregoing description, taken in connection with the drawings, the operation of the inside pivoted and adjustable frame, G, will readily be understood. It is not intended that there shall be much motion to it, as its play is confined within the comparatively narrow space between the coverings E and F, the pressure of the shoulders against partJ forcing back that part of the frame which acts upon the springs on its lower part, and there loses most of its motion, butin so doing serves to keep the npholstering F in front from giving away under pressurethat is, the motion from the top keeps the shape ofthe back firm though soft, and keeps it well filled out, no matter what the position of the occupant may be. This is much preferable to having the lower part, F, of the back pushed out as much 8 as the upper part of frame G is pushed in from the top, because the chair-back, being already properly shaped and adjusted for the occupant, requires only to be kept there while occupied, and this is done by the pressure of the 0 occupants shoulders (or upper bauk)yupon the top of the pivoted frame, which throws the top back, and consequently the lower part of the seat forward, by operating against the springs L in the lower part of the chair-back. This 5 forward movement of the lower part of the back would, however, be too great but for the action of the springs, which enables that part of the seat to yield, while under pressure between frame G and the occupant, so as to asof a person occupying the chair against its upper pert, above the fulcrum, substantially as and for the purpose herein shown and setforth.
In testimony that I claim theforegoingas my 15 own I have hereunto atfixed my signature in presence of two witnesses.

sume the shape and position bestsuited to the comfort of the person seated in the chair.
Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States- In a chair having an upholstered back, a frame pivoted in the sides of the chair-frame Wllhil] the back, provided with springs below its fulcrum bearing against the lower front part of the upholstered back, and adapted to adjust itself by the pressure of the shoulders
