RECLINING 0R INVALID CHAIR.

SPECIFICATION forming part of Letters Patent No. 236,368, dated January 4, 1881.

Application filed February 26, 1880.

To all whom it may concern:

Be it known that I, \VILLIAM S. SINCLAIR, of Niles, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Reclining Chairs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of my reclining-chair, and Fig. 2 is a rear view of the same.

My invention relates to reclining-chairs especially adapted for railway-cars; and the improvement consists in the construction and combination of parts, as fully set forth in the following description and particularly pointed out in the claims.

At the top of the back A of the chair herein illustrated is a reversible section, B, pivoted between two bars or standards, 0 G. hen the lower edge of this reversible section B and the upper edge of the chair-back are in juxtaposition the said section B will be maintained in the plane of the chairback and against any backward tilt by reason of a slight bevel along the opposing edges of the back and of the reversible section. The section B may, however, be swung round in a forward direction, so that when reversed in position it will serve as a pillow for the occupant of the chair. The back and reversible section may be suitably upholstered, and, if desired, the reversible section may be held in the same plane as the back by a latching device.

The standards 0, to which the reversible section is pivoted,extend down upon the sides of [I e chair-back, and are hinged to the chairseat by means of across-rod, E, passed through slotted plates F, which are rigidly secured to the chair-seat. The slots f of these plates are of suflicient length to constitute a sliding hinge-joint between the standards and the chair-seat, and have depressions at their ends for receiving and locking the cross-rod E as the chair-back is thrown forward or backward. The standards 0 contract somewhat toward each other below their hinged connection with the chair-seat, and they extend downward to What I designate a hinged are, Q, to which they are connected by a cross-rod passing from the standards through slots in the supportingarms of the arc. The supporting-aims G of the are are hinged upon studs H, which project from a rotary collar, K, arranged around the pedestal I at its base. This pedestal comprises a hollow cylinder with a vertical rod passing up through its head and secured in any suitable way to the chair-seat, such, for instance, as by aplate or casting bolted to the seat and properly secured to or formed with the rod.

From the studs H of the collar K are upwardly-extending rods or rounds L, which pass through eyes in studs M, which project from a collar, N, said rods L being secured to the seat, so as to effectively support the same.

The are Q is provided with rack-teeth, which engage with the studs M, which project from the collar N, the said collar, which is arranged to have both a vertical sliding and a rotary movement upon the pedestal, being forced upward by coiled springs 0. These springs are arranged upon the rods L, between nuts or lugs r, firmly secured to the rods L, above a lever or step P and the studs M, so that when the collar is drawn down by depressing the lever the arc Q will be disengaged, and hence the chairback may be tilted at pleasure. The pressure being relieved, however, from the lever, which may be connected with the upper collar by connecting-rods, or in any equivalent way, the expansive power of the spring will cause the studs of the upper collar to come into engagement with the rack-teeth of the arc Q.

Upon the forward portion of the arc Q is a short projecting arm, R, which acts against an angularly-bent strap or like cam-surface upon the under side of the hinged leg-board or rest S. This arm R causes the hinged leg-board to be tilted according to the angle of inclination given to-the arc Q, as hereinbefore set forth.

If desired, the foot-board may be provided with hinged legs, so as to support it when the chair-back is thrownforward.

It will be seen from the arrangement of the two bands upon the pedestal that the entire chair mechanism hereinbet'ore described may be rotated around the pedestal. In order to secure the same against rotation when the chair has been brought parallel with the car, I provide a small latchinglever, T, upon one of the studs upon the lower collar, and arrange in the floor or ina suitable plate set into the floorof the car holes for the end of the latch T to take into. I also provide a properly-arranged spring, a, for acting upon the latching-lever. Both this latching-lever T and also the lever P, which serves to disengage the studs from the ratchet-teeth of the are Q, may be readily operated by the foot, thus leaving the operator's hands free to either turn round the chair or tilt its back. In order to bring the chair-back within a required area for turning it round it may be pushed forward over the seat, the rod E sliding forward in the slotted plates and then dropping into the forward notches of the slots f.

The chair is provided with hinge-jointed arms, connecting the back and seat, so as to admitof a ready tilting of the back.

Having thus described the construction and arrangement of my improved chair, What I claim, and desire to secure by Letters Patent, 1s

1. The combination, in a chair, of the tilting back having the standards 0 connected to the seat by the slotted plates F, and a rod, E,

passed through the slots in the plates F, with the arc Q, having ratchet-teeth, and slotted supporting-arms G, hinged to the collar K at the bottom of the pedestal I, substantially as and for the purpose set forth.

2. In a chair, the combination of the pedestal I, provided with the collars K and N, having studs H and M, the rods L, having nuts or lugs 1', and springs O, With the lever P, connected by rods with the studs M of the collar N, the latch l, and the arc Q, supported by the arms G, substantially as and for the purposes set forth.

3. In a chair, the combination of the arc Q, supported on the hinged arms G, and provided with an arm, It, with the hinged leg-board S, having an inclined projection for the arm It to act upon, substantially as and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

W ILLIAM S. SINCLAIR.
