CHARLES O. SCHMITT,

IMPROVE OF NEV YORK, N. Y.

D CHAIR- Specilicnlion forming part of Letters Patent No. 58,682, dated October 9, 1866.

To all whom it may concern:

Beit known that I, C. C. SCHMITT, of the city, county, and State of New York, have invented a new and useful Improvement in Chairs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The present invention consists principally in so arranging or constructing the frames of that class of chairs having the material used for its seat and back made of a continuous strip or piece of cloth or other suit-able matc- -rial, that while the back of the chair can be adjusted to any desired inclination, whether more or less, from a vertical to a horizontal plane, or nearly so, the strip of cloth or other material constituting the back and seat of the chair can be let out or taken up to suit the inclination to which the back of themchair is adjusted and set, as will be obvious from the following detail description of the saine, reference being had to the accompanying plate of drawings, in which- Figure 1 is a front view and elevation of a chair made according to the present invention, and Fig. 2 a central vertical section taken in the plane of the line a: Fig. l.

A in the drawings represents the chair, which consists of two frames,B and G, hinged or pivoted together at D, the one B within the other, so that they can be opened from and closed upon eachv other at pleasure, with the lower portions of the two frames, or that below the point D of pivoting, constituting the legs of the chair, while the upper portion ofthe two frames constitute, the one,B, the back, and the other, C, the seat, as embraced by the space E, between .the upper end of the said frame C and the other or back frame B, when opened from each, as shown in Fig. 1 of the drawings.

At the upper end F of the back-frame C a roller or round, G, is secured, to which is secured one end of a strip or piece ot' cloth, H, or other suitable material ordinarily employed for upholstering or covering chairs or other articles of furniture, the other end being secured to a roller, I, extending across and between the upper ends of the frame C, to which it is hung so as to be revolved, and thus enable the said cloth to be wound around and upon the same, or unwound therefrom, according as it may be desired to lengthen or shorten the said cloth, to adjust it to the inclination of the back-frame, as will be hereinafter explained.

This roller-I at one end is provided with a ratcliet-wheel, J, with which a spring-pawl, K, engages, hung in and to the arm-post L ot' the chair, hung so as to swing thereon at a corresponding end to that at which the said ratchet is secured; this pawl being pivoted to engage with the said ratchet so as to hold the roller in position and prevent the cloth wound upon it from unwinding.

Mis a leverhnn g in the arm-post L, in proper position. to raise the spring-pawl K from the ratchet-wheel, an-d thus disengage it when desired to unwind the cloth; N, an arm-post hung to the opposite end of the chair-frame C to that where the arm-post L is secured, to each of which arm-posts N and L one end of belts O are hung, that at their opposite ends are secured to the chairback frame B, and are both so arranged that by means of buckles l? they can be lengthened and shortened at pleasure.

To the rear side of the chair-back frame B ratchet or toothed bars Q are secured, extend ing from the point D, at which such frame is pivoted, to the other frame upward a short distance, with which ratchet-bars a cross-bar, S, by means of an elastic loop, T, is so hung to the center round, U, of the chair that it may be made to engage with or be disengaged from the said ratchet-bars at pleasure; the said crossbar S, when engaged with the teeth of the said ratchet-bars firmly holding the back frame in whatever positionit may be set or adj usted, whether more or less inclined.

From the above description it is plain to be seen that by the construction of the chair its back can be adjusted and set at any inclination desiredfwhether more or less, when changing the length of the strip of cloth to /correspond thereto-that is, either lengthen or shorten it more or less by unwinding it from or winding it upon the roller, the seat and back of the chair can be properly adjusted to the inclination of the chair-back, to render the frame that it can be lengthened or shortened,

chair easy and comfortable in use. in the manner herein specified, and for the Having thus described my invention, l claim purpose set forth.

as new and desire to secure by Letters Pat- The above specification of my invention entsigned by me this lst day of July, 1866.
