CHAIR.

Specification of Letters Patent.

Application filed February 13, 1911.

Patented May 14, 1912. Serial No. 608,184.

To all whom it may concern:

Be it known that I, CASPER J. CAIN, a citizen of the United States of America, residing at Stockbridge, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Chairs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to adjustable reclining chairs, and it has for one of its objects the provision of an article of furniture of this class, in which the seat is supported on a pivoted shoe which accommodates itself to the different inclinations of the seat.

The invention has furthermore for its object of the provision of a hinged back and seat, the reclining position of which may be varied by the person seated in the chair without the necessity of unlocking and relocking the parts; in fact by merely leaning back until the desired position has been reached.

The invention has also for its object the provision of a chair in which the seat and back are maintained in their positions by the full surface-friction established between the seat and the shoe upon which it rests, the shoe having a vertically yielding support to produce a cushion or spring-effect.

Further objects of the invention will hereinafter appear and be particularly defined in the claims:

The invention has been clearly illustrated in the accompanying drawings, in which similar characters denote similar parts, and in which Figure 1 represents a central vertical section of a chair embodying my invention; Fig. 2 is a top view thereof, partly broken away, and Fig. 3 illustrates a fractional section, similar to Fig. 1, of a simplified form of seat-support.

Briefly stated, my improved chair comprises a seat and back which are hinged together, the back being pivoted on afixed point of the frame and comparatively near the junction of the seat and back so that a small pressure exerted by a person leaning back will tilt the chair-back rearward and at the same time move the seat bodily forward on a frictional supporting shoe. The chair seat and back will resume their normal position as soon as the weight or pressure on seat and back are relieved.

Referring to the drawings, the frame of the chair comprises front rails 10, 11, and a pair of side rails 12, all supported by posts or legs of any desired design or construction. Pivotally supported by and between the rearlegs 13, as at 14, is the chair-back B, the pivot point being comparatively low so that a light-backward pressure on the front face of the chair back B will suffice to tilt the same backward and simultaneously move the seat S forward, both being hinged together as at 15. While the rear edge of the seat S 1s in this manner positively guided for movement around the back pivot 14, its front and central weight-sustaining portions are supported on a pair of shoes 20 which have a preferably flat wearing face 20 of consider able length to provide not only a smooth surface but also to distribute the weight over a comparatively large area and thus prevent surface-indentations which might otherwise occur.

In order to adapt the shoes to their proper function, they are hung in such a manner that they can accommodate themselves to the angular variations of the seat in different reclining positions of the back B. For this reason the shoes are preferably pivoted, as at 21, on pins 22 which are attached to the side rails 12, either directly, as shown in Fig. 3 or indirectly through the intervention of springs 23 as shown in Figs. 1 and 2, in which the latter are shown as blade-springs supported on brackets 24 secured on the siderails 12. In this instance the seat will naturally have a yielding or cushion support. One or more springs 25 may be used for returning the back and seat to their normal positions resting against the rear-rail 11, as soon as these elements are relieved from counteracting pressure.

Inasmuch as changes in the construction or organization of the several elements may readily be made without departing from the spirit of the invention, it should be understood that I do not confine myself to the particular forms shown and described, especially as to the manner of changing the seatsupporting shoes and the chair-back.

I claim:

1. The combination with the frame of a chair, of a seat, a back pivoted on said frame, a hinge-connection between the lower end of the back and the rear edge of the seat, a shoe having a long frictional bearing-face supporting said seat, a bolt for pivotally supporting said shoe, and a spring for yieldingly supporting said bolt on the frame, means for retracting said seat and back to their normal. positions.

2. The combination with the frame of a chair, of a seat, a back pivoted on said frame, a hinge connection between the lower end of the back and the rear edge of the seat, a shoe supporting the forward end of the seat, and a blade spring secured at one end to the frame and pivoted at its free end With said shoe.

3. The combination with the frame of a chair comprising side rails, of a seat, a back pivoted on the frame, a hinge connection between the rear of the seat and the lower part of the back, shoes slidably. supporting he front end of the seat, brackets attached to the side rails of the chair, and independent blade springs attached to said brackets and pivotally supporting said shoes.

4. In a reclining chair, a stationary frame, a tilting frame mounted on the stationary frame, a pair of arms secured to the stationary frame and being yieldable bodily from their securing means to their opposite ends, 4.

a brake shoe on each arm at its said opposite end and adapted to be held normally in engagement with the tilting frame, by the resiliency of said arms, so that upon tilting movement of the tilting frame, the frictional CASPER J. CAIN. Witnesses J. B. HUBERT, A. A. HALL.
