SPECIFICATION forming part of Letters Patent No. 748,903, dated January 5, 1904. Application filed September 14, 1903, Serial No. 173.077 (No model.)

To (ZZZ whom it may concern;

Beit known that LHUBERT W'ITTE,a citizen of the United States, residing in the city of St. Louis and State of,.Missouri, have invented certain new and useful Improvements in Car- Seats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements in that class of car-seats known as walk-over seats, an illustration of which may be found in Letters Patent of the United States issued to the St. Louis CarQompany March 19, 1901, No. 670,190. The invention consists in features of novelty hereinafter fully described, andpointed out in the claims.

Figure I is a front elevation of one end of my car-seat with parts broken away. Fig. II is a vertical cross-section of the seat. Fig. III is a perspective view of the cushion-shifting, mechanism; Fig. IV is a top or plan View of one end of the seat with the cushion and back omitted.

As the two ends of my seat are duplicates, the description will be considered as applied to the entire seat, though but one end there of is shown.

2 the end frames, which are provided with.

curved slots 3, towbe hereinafter more particularly referred to. The pedestals l are united by longitudinal tie-bars4, andthe end frames are secured to the ends of said tie-bars.

5 designates cross-bars mounted on the longitudinal tie-bars 4, of whichmore particular mention will hereinafter be made.

The above-mentioned parts form the frame of the seat.

6 designates the back of the seat, which carries downwardly-extending arms 7. At each end of the seat is a link 8, the lower end of which has a slot-and-pin connection at 9 with the seat-arms 7 i The upper ends-0f the links 8 are pivoted at 10 to the end frames 2, and the central parts of the links are widened and contain elongated openings 11.

l2 designatesa rock-shaft journaled in the end frames 2 and extending longitudinally of the seat between said frames.

This rockshafthas fixed to it near each end a foot-rest frame 13, having a pair of arms that carry foot-receiving rods 14, which move with said foot-rest-frame arms and with the rock-shaft 12 when said shaft is rotated.

15 designates levers, each fixed at one end to the rock-shaftl2 and pivoted at'the other end at 16 to the back-arms 7. Seated in each lever 15is a pin 17, that is adapted to ride in the curved slot 3 in the adjacent seat end frame 2 and also in a slot 8 in the adjacent link 8.

Pivoted to the cross-bars 5 of the seat intermediate of their ends, as seen at 19, Figs. II and III, are rockers 20, having downwardly-extending slotted arms 21 and upwardly-extending slotted arms 22. Each rocker-arm 21 is connected to the adjacent lever 15 by a pin 23, projecting fromsaid lever to operate in the slot of the arm.

24 designates cushion-supports on which the cushion 25 is mounted; Seated in these supports are pins 25, that pass through the slots in the upper rocker-arms 22 to operate therein.

When in the practical use of my seat the parts are to be shifted to reverse the position of the seat-back with respect to the cushion, the seat mechanism is operated as follows: As the back 6 of the seat is shifted to the opposite side of the cushion from that at which it was previously located the lovers 15 serve as pivot members on which the back is carried over. At the same the lower ends of the back-arms 7 operate pivotally in the lower ends of the links 8 and swing with said links to the opposite side of the seat. In the movement of the levers 15 during the shifting of the seat-back the rock-shaft 12, to which said levers are fixed, is rotated, and therefore the foot-rest frames, with the footreceiving rods, are oscillated forwardly, so that the rods will be carried into positions where they will constitute the least obstruction beneath the seat, as illustrated in Fig. II, so that there may be as near as possible a clear space beneath the seat. When the seat-back is shifted and the levers 15 moved, as stated, the pins 17, carried by said levers, operate in the lower rocker-arms 21. Through this engagement the rockers 20 are oscillated intermediate of its ends forvengagement in said curved slot, a reversible back pivoted to the upper end of said lever, a link pivoted to the frame and having slot-and-pin connection with the lower end of the reversible back, and a link having slot-and-pin connection with said lever and said cushion-supports for shifting the cushion when the back is reversed.
