IMPROVED RAILWAY-CAR SEAT.

Specification forming part of Letters Patent No. 95,283, dated September 2B, 1869.

To all whom it may concern:

Be it known that I, JOHN B. SUTHnRLAN-D, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Car-Seats, and I do declare that the following is a true and accurate'description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, and being a part of this speciiication.

Figures 1,2, and 3 are vertical sections upon the line y y in Fig. 5. Fig. 4 is a longitudinal vertical section upon the lines .T in Fig. 3,' and also showing a plan or front elevation of the seat-back. Fig. 5 is a plan view from the top.

Like letters refer to like parts in each figure.

The nature of this invention relates to an improvement in the construction of car or' other seats, so that the same will be reversible, and its parts so arranged that the reversing lof the back will also cause an adjustment of the seat, so that when the back is set at a proper angle the seat will be inclined downward and backward from the front edge, thereby conducing greatly to the comfort of the sitter.

The invention consists in a peculiar arrangement of compound. levers, upon which the seat is hung, in such a manner that when the back is reversed the seat is adjusted, as hereinbefore described. It also consists in a novel arrangement of the various parts, hereinafter more fully described, by means of which the seat is irm, and its liability to rocking or vibration avoided, such liability being common and unavoidable in allseats designed for a similar purpose, where the seat is pivoted on a rod or axisunder the seat, and no rest provided for the front of the seat.

1n the drawings, A represents a seat-frame, to which is pivoted in the usual manner the reversible back B by the arms C. Pivoted to the arms G, at ct, are the lifting-arms D, which, with the arms G, form a compound lever, for the purpose hereinafter specified. These arms D are provided with a recessed slot, b, which engages with the pin d, which is rigidly secured to the inner face of the seat-frame. Projecting inward from the lower ends of the arms D, and rigidly secured thereto, are the pins h. E is a seat of any desired construction, to the under side of which, at one or both ends, as may be desired, are secured the curved guides F, which engage with the rigid pins la, which are secured to the inner face of the frame A, below the position'designed for the seat when in place. Lugs or rests m are rigidly secured to the corners of the seatframe. At each end of the seat, and under the center thereof, is a semicircular recess, (not shown in the drawings,) which engages with the pin h, as hereinafter described.

In Fig. 1 the back and seat are shown in position for occupancy. In Fig. the samelis shown reversed, and in Fig. 2 the reversion is being made, showing .the seat suspended at its center by the engagement of the semicircular recesses with the pins h, hereinbefore described.

It will be seen that in Figs. l and 3 the front of the seat rests upon the front of the seatframe, while the rear of the seat rests upon the lugs or rests m. While the seat is in this position its center does not rest upon the pins h. In the movement to reverse the back of the seat B, the eccentric movement of the arm D causes the pins h to engage with the semicircular recesses in the under side of the ends of the seat from its position upon thel frame and rest. As the back is thrown over the seat is carried forward, being guided by the curved guides F engaging with the pins k,

and when the back arrives at its reversed position the seat is deposited upon the seat front and rest, upon the opposite sides upon the front and rest.

,Where a wooden clatted seat and back are used, the guides F and pins k may be omitted, andthe tilting of the seat be effected by having a guide-lug, k', on each of the end standards of the frame. Against the under sides of these lugs the edge of the seat presses, and is guided in its passage, and prevented from rising any higher than is necessary to lap over the seat-frame.

The whole operation is fully shown in the first three figures of the drawings, and can be seen so clearly that a further description thereof is deemed unnecessary.

l. am aware that there are devices in use for reversing the seat-back and adjusting the seat, so that when ready for occupancy the inclination of the seat will be to the rear and down- Ward; but in all these devices the seat rests upon a pivot or axis under the seat, so that it rocks or otherwise moves with the motion of a railroad-car.

My devices, as I have already described, al 10W the seat to rest upon a firm, unyielding, and steady base when ready for use; there- Afore,

What I claim Yas 1ny invention, and desire to secure by Letters Patent, is-

1. The compound levers formed by the arms C and D, pivoted together at a, and the latter l provided with slot b and pins h, in connection with seat-back B, and seat-frame A, and seat E, substantially as herein set forth.
