REVERSIBLE CAR-SEAT.

$PECIEICATION forming part of Letters Patent No. 371,371, dated October 11, 1887.

Serial No. 217,800. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN M. SAUDER, of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and Improved Reversible Oar-Seat, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved reversible car-seat in which the seat and its back are permanently united and both reverse as a whole on a stationary base or pedestal.

The invention consists of a united seat and back supported on a base, and arms pivoted on the said base and connected with a head, forming a universal joint with a plate on the bottom of the seat.

The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view of my improvement, parts being in section. Fig. 2 is a side elevation of the same with parts in section. Fig. 3 is a detail view of the universal joint. Fig. 4 is a sectional side elevation of the same on theline was of Fig. 3, and Fig. 5 is a plan view of the same. Fig. 6 is a sectional side elevation of a universal joint of modified form, and Fig. 7 is a face view of the washer used in connection with the head shown in Fig. 6.

The seatA and the back 13 are permanently united with each other in any suitable manner, and the seat A is provided with the downwardly and rearward! y extending legs 0, united by the usual foot-rest, D. On the bottom of the scat are secured the plates E E, each having a central depression, into which fils the pointed end of an arm, F, extending one at each side from the base or pedestal G, resting on the floor.

In the middle of the under side of the seat A is secured the plate II, provided with the spherical cavity H, in which tits the ball I, formed on the head J, connected with the said plate H by a bolt, K, which passes through the conical opening I of the ball I and is screwthreaded on its upper end, on which screws the nut K upon the spring-plate I resting in the cavity H of the plate H. The head K of the bolt K is held in the recess 1 connecting with the conical opening I. To the fiat part J of the head Jare pivotally attached the upper ends of the parallel bars N N, pivoted at their lower ends in the base of the pedestal G to one side of the center of the same.

Instead of the two parallel bars N, or in connection with the same, I may employ one or two central bars, 0, pivoted in the center of the flat part J of the head J by means of a bolt, P, having its head P and its nut P resting on the spring-plates Q, which fit into cavities formed in the said bars 0, and which also have their concave shaped pivoted ends fitted into corresponding cavities on the said part J of the head'J, as shown in Fig. 6.

The operation is as follows: It will be seen that the seat A, supporting the back B, rests on the armsF and the legs 0. Now,whcn the operator desires to change the position of the chair,he pulls sidewise, in the direction of the arrow a, on the chair, which causes the seat and its back to swing upward, the bars N being the fulcrum, to the position shown in dotted lines in Fig. 1, whereby the plates E on the seat A are disengaged from the pointed ends of the arms F and the legs 0 are raised from the floor. The operator can now turn the seat on the ball I of the head J to an opposite position without interfering with the adjacent seats. As soon as the desired position is at taiued the operatorswings the seat to its former position, so that the plates E again engage with the pointed ends of the arms F and the legs G rest on the floor. The spring-plate L in the plate H, attached to the car-seat, furnishes the necessary tension in turning the seat.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a reversible car-seat, the combination, with a seat and its back, of a base having arms supporting the front of the seat, bars pivoted to the said base, and a head pivotally connected with the said arms and forming a universal joint with a plate on the seat, substantially as shown and described.

2. In a reversible car-seat, the combination, with a seat and its'back and legs extending from the rear of the said seat, of a base having arms supporting the front of the said seat, bars pivoted on the said base, and a head pivotally connected with the said arms and forming a universal joint with a plate onthe said seat, substantially as shown and described.

3. In a car-seat, the combination,with a seat, of a base provided with arms supporting the said seat, bars pivoted on the said base, and a head pivotally connected with'the said bars andforming a universal joint with a plate on the said seat, substantially as shown and described.

scribed.

5. In a reversible car-seat, the seat A and the plate H, secured to the bottom of the said seat and having a spherical cavity, H, in combination with the base G, the head J, provided with the ball I, having the conical opening I, the plate K, held in the said ball I, the springplate L, held in the cavity H of the plate H by means of the nut K on the said bolt K, and the parallel bars N, pivotally connected with the said head J and the base, substantially as shown and described.

6. In a reversible ear-seat, the seat A, the plate H, fastened to the said seat, and the spring-plate L, held in the cavity H of the said plate H, in combination with the head J, provided with the ball I, fitting in the spherieal cavity H of the said plate H and having a conical opening, I, the bolt K, held in the recess I of the said ball I, passing through the said conical opening I, and the nut K, screwing on the threaded end of the saidbolt against the spring-plate L, the base G, and links connecting said base and head, substantially as shown and described.
