IMPROVEMENT IN RAILWAY-CAR SEATS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it lmay concern:

Be it known that I, EZRA MILLER, of the city and j countyv of New York, inthe State of New York, have 'invented aV new and improved Back-Rest for Car- Seats; and I do hereby declare that the following is a. full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specilication, in which- Figure 1` is a vertical cross-section of a railroad-car seat having my improvement applied to it.

Figures 2.and 3 are enlarged views of thc grooved rest.

Figure 4 is a pelspective view of the Thead on the arm of the back.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates t0 an improvement on the back-rests for car-seats, whereby hooks or projections,

which frequently tear the clothes of passen gers, are dispensed with, and in lieu thereof grooved rest-plates on the seat-arnxsare employed, in combination with projections on the arms ofthe back, as will be hereinafter explained. y

-To enable others skilled in the art t understand my'invention, l will explain its construction and operation.

1n the. accompanying drawings, lig. 1, l haverepresented 'a car-seat having its back B pivoted at g to the seat-arms A by means of the swinging arms E, so that the back can be reversed or turned over to either side ofthe seat.

This is the usual well-known manner of constructing reversible car-seats, the backs B of such seats being supported by means of hooks, which are formed on or applied to the inner sides of the seat-arms, on which hooks the back arms-rest. It is these hooked projections which are so objectionable, and which l get rid of by my improvement.

On the outer side of each back-arm E I form a projection, J, which is preferably made of the T-shape shown in figure 4, and to the inner side of each seatarm A, I apply two grooved rest-plates 0,*c, in such position relatively to the projection J- on thearm E that this projection will be received into the groove a of one of said plates, whether the seat be turned to the right or left, as indicated by the dotted line in ligure. 1.

Each plat-e O is constructed with an upwardly-liaring groove, a., which is adapted to receivethe projections J on the .back arm, and which is concentric to the axis of motion ofthe seat-back B.

The' T-shaped slot, a, in each plate C, in combination with a similarly-shaped projection J on the arm E,- will afford a firm support to the back B against lateral thrust, andthe abutment, b, at the lower termination ofthe slot a, will support the back B, at a proper height. In other respects the rest-plates C may be constructed as fancy may dictate. The shape shownin figure 2 will allow the said plate to be secured to the horizontal and vertical portions of the seat-a rms, and for this reason such shape is preferred.

ltwill be seen from the above description that the grooved rest-plates C do not offer projections which would be liable to catch or tear the clothing, owing to the holding and supporting portions of these plates bef ing received in-to their exposed surfaces. At the same time it will be seen that the arms E of the seat-back will be prevented form lateral motion or displacement when rest-ing upon the shoulder b.

The principle of my invention, therefore, consists in transferring the projections from the seat-arms to the back arms, and in employing upon the seat-arms a female or countersunkrest for said projections, as above shown.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

A back-rest for reversible car-seats, consisting ofA projections J on the arms of the back of the seat, and recesses applied tothe arms of the seat, adapted to receive such projections, substantially as described.

EZRA MILLER. Viitnesses:
