CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 365,418, dated June 28, 1887.

Application filed April 23, 1886. Serial No. 199,896. (No model.) I

- as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates toan improvement in car-seats.

Hitherto car-seats have generally been providedwith non-tilting backs, or with backs The object of my present invention is to provide a car-seat in which the back may be tilted at any desired angle to the seat.

A further object is to provide a car-seat adapted to use in both day and sleeping cars, and to further provide simple, durable,'and efficient mechanism for tilting and supporting the back.

With these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure I is an end view of a car-seat embodyingv my improvement, with the back at an angle of fort yiive degrees. Fig. 2 isa detached view of a connecting bar or link, 9. Fig. 3 is a view of the same in another position. Fig. 4 is an end view of two seats with the'back of the front one in horizontal adjustment.

A represents a car-seat suitably supported on legs B,and provided at its ends with frames 0, the upper parts of which form the armsupports D. Just below the arm-rest, and preferably formed integral therewith, and extending to the edge of the seat, are located two slotted inclines, E E, which come together at the end of the seat. They are provided on the lower sides with ratchetteeth e, the purpose of which will be explained farther on.

F is the back of a seat secured in rocking adjustment by pins H, resting in, hooks I at the back of the seat. The seat is provided with hooks I, in a corresponding position on the opposite side, adapted to form rests for the back of the adjacent seat when the latter is tilted horizontally, and also to receivethe pin H when the back is reversed. A connecting bar or link, G, having one of its ends pivotally secured to the end of the back and the pointed'noses k, which are adapted to fit in the ratchet-teeth of the inclines E E,is adapted to be secured at its catch end in the said slotted inclines. The adjustment ofthis catch is regulated by means of a thumb-screw, L. A washer, M, is placed between the screw and the catch for locking the latter in proper position, and when it is desired to vary the height ofthe back the screw is turned, which leavesthe catch free to slide freelyv over the teeth or notches until the desired elevation of .other provided with a catch, K, having two i the back is reached, when the catch is again turned to fit between two ratchet-teeth, thus firmly holding the back at any desired inclination.

I am aware that it is old to connect a movable seat-back to the seat-frame byside arms, the latter forming arm-rests, and pivotally secured to the back-rest, and provided at their lower ends with studs adapted to engage or enter horizontal slots formed in the seat-frame and hold the back in any desired adjustment; and hence I make no claim, broadly, to such a construction. In my device the-seat-frame, at a point below the rigid or stationary armrests, is, provided with inclined slots having notches adapted to be engaged by studs formed on links, which latter are pivotally secured to the back-rest.

It is evident that slight changes might be resorted to in the form and arrangement of theseveral parts described without departing from the spirit and scope of my invention.'

supported on tl1eseat-fran1e,and the link pivnected thereto, a double-nosed catch secured oted to the back and provided on its free end to the link, and a thnmb-serew and washer with a rigid catch adapted to engage the teeth for locking the catch against displacement, in" the lower wall of the groove, the said catch substantially as set forth.
