BERNARD SCHECHTER, OF ST. LOUIS, MISSOURI.

SEAT.

Specification of Letters Patent.

-Patented Apr. 22, 1212.

Application filed October 31, 1918. Serial No. 260,493.

To all whom it may concern:

Be it known that I, BERNARD SOHEGHTER, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Seats, of which the following is a specification.

This invention relates to seats adapted to be used on trolley and railway cars, omnibuses, other vehicles, and the like, and wherever seats are arranged adjacent to an aisle, or the like.

Its object is to provide an adjustable or reversible seat of simple and strong con struction, consisting of few parts. By reason of its construction, the seat-back can be shifted to a position adjacent to either of the opposite edges of the seat-bottom or cushion and by that movement the seat support is advanced and tilted to a convenient angle from the horizontal so as to put the seat in a position comfortable for the occupant of the seat. Although this construction is cheap and light, it is adequately firm and rigid.

The seat is hinged to adjacent parts so that it can be readily lifted on either of its opposite side edges and folded up toward the seat-back and may also be dropped readily from folded to usable position.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a perspective view;

Fig. 2 is a side elevation, the principal parts being shown in dotted lines;

Fig. 3 is a sectional view taken on the line 3-3 in Fig. 2;

Fig. 4 is a detail view on an enlarged scale;

Fig. 5 is a detail perspective view of one of the wall-plates;

Fig. 6 is a detail perspective view of one of the tie-plates; and

Fig. 7 is a detail perspective view of one of v the seat-rockers.

' The side wall 1 of the vehicle supports the angle iron 2, to which is bolted the wallplate bracket 3, to which is bolted the housing or wall-plate 4:, which forms a support for one end of the seat, the other end being, through intermediate parts, supported by Aisle-plate 5 is supported by pedestal 6., 1 V V The seatback 7 can be moved from one side to the other of the seat 8, being pivoted at 9 to lever 10 and at 11 to lever 12. The opposite end of lever 10 is pivoted to an end of seat-rod 13 and the opposite end of lever 12 is fixed to an end of seat-rod 14:.

Seat-rocker lever 15 is fixed to seat-rod 14.- and is provided with a stud 16 that projects into socket 17 that is cast integral with seatrocker 18.

Studs 19 project from opposite ends of seat-rocker 18. Socket 17 is cast integral with seatu'ocker 18 and has a vertically depending part 20, in which stud 16 can move. A plate 21 underlies seat-rocker 18 and acts as a seat-rocker guide, groove. 22 being formed between the said plate and the seatrocker guide. A tongue 28 having at its end a hook 2i and cast integral with plate 21 projects through the said groove 22. Hook 2% thus holds seat-rocker 18 in place.

Seat-rocker lever 15 is fixed by collar 26 to shaft 1% and therefore rotates therewith.

Most of the above-mentioned parts are in duplicate, one each being located at each end of the seat-rods 13 and 14:.

Plate 21 is fastened above flange 27 on the wall-plate and another plate 21 is fastened above flange 28 on the aisle-plate. Plate 21 is in the form of a flange from a member riveted to wall-plate 4 or aisle-plate 5.

Tie-plate 25 is bolted to plate 21 and also to walLplate a or the aisle-plate 5, and is provided with apertures through which the seat-rods 13 and 14: pass to their connection with the seat-levers 10 and 12.

Doublehinges 29 are suitably attached on the top of one pair of studs 19. A hingejoint 30 allows the seat to be upturned in the direction shown in Fig. 1, while the hingej oint 31 allows it to be upturned in the op 0- site direction when on the other side of t e seat support.

Studs 32 on the top of the strap of hinges 29 are adapted to center in sockets 33, which assists in keeping the seat from side-swaying or. disarrangement of the parts.

It should be understood that the precise curvature of the flanges 27 and 28 and of the plates or guides 21 fastened thereto and within the wall-plate 4 and aisle-plate 5 and the corresponding curvature of the seat rocker 18, is important in producing exactly the most convenient and easy movement of the parts when it is desired to shift the seatlilll back 7 from one side of the seat to the other and the right tilt or angle of the seat for comfort.

This shifting is accomplished by taking hold of the seat-back by the handle 3% and applying force thereto. Seatback lever 10 being pivoted at 13, as well as at 9, adjusts itself freely to this movement, but lever 12 being fixed to seat-rod 14, causes the same to rotate and thus to cause stud 16 on seatrocker lever 15 to descend in socket 17 and there to apply force to push seat-rocker 18 in the direction opposite to the direction of travel of seat-back 7 which, on account of the curvature of the flanges 27 and 28, as Well as the predetermined degree of travel of seat-rocker 18, results in the seat 8 having an agreeable and comfortable inclination or slant for sitting in the opposite direction when the back 7 has been moved its limit of travel.

Tie-plate 25 is bolted to plate 21 and also to wall-plate l or aisle-plate 5 and is provided with apertures 35, through which seatrods 13 and 1% pass to their connections wlth levers 10 and 12.

Having thus described this l11\'611tlOl1, I hereby reserve the benefit of all changes 1n form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claims.
