To all whom t may concern.'

Be it known that I, JOHN EDWIN KIL- BURN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in` vented certain new and useful Improvements in Reversible Car-Seats, of which the following is a specification.

My invention relates to reversible seats for railway carriages and the like, and the object of the invention is to effect certain improvements in the construction of seats of this type, whereby they are made easily reversible, the proper inclination of both the back and the seat are obtained, the seat is moved simultaneously with the reversal of the back and in the same direction, and a simple and compact construction is provided.

In accordance with the invention, as stated, a very simple construction of reversible car-seat is provided wherein the seat is moved bodily in the same direction as the back when the latter is reversed, being so arranged that the seat will, in either position, be inclined at such an angle as will make it most comfortable for occupants of the seat. Movement of the seat in the same direction as the back when reversal is leffected is sometimes desirable for the reason that greater knee-room is provided when two seats are facing each other, the construction also permitting the installation of a greater number of seats in a car of given length. Thus when the backs of a pair of adjacent car-seats are moved to the distant edges of their cushions so that the occupants sit facing each other, the seats or cushions are moved backwardly in each instance, and when one of the backs of this pair of seats is reversed so that the occupants of the seats are facing in the same direction, the seats will be closer together, because of the movement of the seat the back of which was reversed. By this means, space within the car is economized, less space being required between the seats when they are facing in the same direction and accordingly more seats can be used in a car under these conditions.

In order that my invention may be more .clearly understood, attention is hereby directed to the accompanying drawings forming part of this specification and illustrating the preferred form of my invention. In the drawings, Figure 1 represents a side elevation of the seat, the back being in one of its extreme positions, Fig. 2 is a front elevation of the seat with the back shown in intermediate position during its movement of reversal, and Fig. 3 is an enlarged sectional view of a part of the mechanism shown in Fig. 2.

Referring to the drawings, the reference character 1 represents the usual aisle pedestal and 2 the foot rest. The cross-members 3 and 3, preferably structural shapes, serve to connect the aisle pedestal and the wall support for the seat. The seat 4e of anyT desired construction is secured to metallic rockers 5 and 6 which are slidably mounted on members 7 and 8 secured to the cross-member 3 and similar members secured to the cross-member 3 to permit the desired movement of the seat when the back is reversed. The seat may, if desired, be removably connected to the rockers by a pin and socket connection as indicated. The rockers are provided on their under sides with inclined surfaces 9 and 10, and plane surfaces 11 between the inclined surfaces. The parts are so positioned that when the seat is in the position shown in Fig. 1, the forward edge of the rockers in advance of inclined surfaces 9 is supported by the guiding tracks 7 and 8, the guides secured to the rear cross-bar 3 contacting the under sides of the rockers in advance of the inclined portions 10 of the rockers so that the forward edge of the seat is raised in the well known manner. When the seat and back are reversed, surfaces 9 of the rockers move olf of their supports and surfaces 1() move over their supports to similarly raise the other edge of the seat which now becomes the forward edge. The back 12 is provided on its side edges with metallic members 13 to which arms 14 are pivoted upon pins 14 at points somewhat above the middle of the back. Arms 14 each carry at their lower ends a pair of rollers 15 and 16 running on a curved track 17 at each side of the seat, the track on each side being supported in a frame 18. The tracks are preferably made yof stamped metal formed with upper and lower flanges between which the rollers 15 and 16 are guided as illustrated. Links 19 are provided, one on each side of the seat, to control the angle of the back and also to move the seat-cushion when the back is reversed. Links 19 are pivoted at their lower ends on a rod 20 extending transversely beneath the seat and carried by the stationary frame.c Links 19 at their upper ends carry pins 21 which are slidably mounted in slots 22 at the lower ends of members 13 on the back. Links 19 also carry pins 23 which slidably engage Within slots 24 at the lower ends of arms 14, slots 24 being provided in portions of arms 14- intermediate between the forward rollers 15 and the rear rollers 16. By this arrangement when the back is reversed, the rollers 15 and 16 move in tracks 17, pins 21 and 23 move in their respective slots, the back and arms 14 being appropriately guided in their movement and the reversing movement of the back is smoothly accomplished. Arms 14; are bent or offset as indicated at 25 in Fig. 9J, to make room for the upper ends of links 19 which are positioned between arms 1li on the one side and members 13 secured to the back on the other side.

Links 19 are each provided a short distance above their pivots on rod 2O with laterally extending pins 2G which engage within vertically arranged slots 27 provided on the under sides of the rockers. Accordingly, when the back is reversed, the seat is moved in the same direction by the engagement of pins 26 in slots 27 of the rockers, the extent of movement of the seat being determined by the length of the lever arms of pins 26. In practice, anv advantageous arrangement has been found to be to space the seats so that the knee-room between the cushions ofadjacent seats is approximately fourteen inches when the seats all face the saine way, and to provide for a receding movement of one cushion of-two inches when the seat is reversed so that when a pair of seats are arranged face to face, there will be sixteen inches knee-room between the cushions.

Having now particularly described my invention, what I claim and desire to protect by Letters Patent is as follows 1. In a reversible car-seat, the combination of a support, curved tracks supported thereby, rockers slidably mounted on said support and a seat carried thereby, a back movable from one edge of the seat to the other to reverse the facing direction of the seat, arms pivoted to the back intermediate its top and bottom and carrying rollers run-v ning on said track, links having fixed pivots at their lower ends below the seat and .having pin and slot connections with said back and also with said arms, said links also having pins above the pivotal points thereof engaging slots in said rockers to move the seat in the same direction as that of the back in reversal, substantially as set forth.

2. In a reversible car-seat, the combination of a support, curved tracks supported thereby, rockers slidably mounted on said support and a seat carried thereby, a back movable from one edge or the seat to the other, arms pivoted to the back intermediate its top and bottom and carrying at their lower ends rollers running on said tracks, said arms having downwardly extending slots at their lower ends between said rollers, and said back having downwardly extending slots at the lower portions of its ends, and links having fixed pivots at their lower ends below said seat and having pins slidably engaged within the slots in said arms and said back, said linksv also having pin and slot connections with said rockers, substantiallyas set forth. c
