DAVID BUZZELL, OF GHARLES'IOWN, MASSACHUSETTS.

RAILROAD-CAR SEAT.

Specification of Letters Patent No. 19,910, dated April 13, 1858.

To all whom it may concern:

Be it known that I, DAVID BUZZELL, of Charlestown, in the county of Middlesex and State of Massachusetts, have invented a new and useful Railway-Car Seat or Becumbent Chair; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure 1, denotes a side elevation. Fig. 2, a front elevation; Fig. 3, a vertical, central and longitudinal section of such car seat or chair. Fig.4, is a View of the operating mechanism within the reversible back tobe hereinafter described. Fig. 5, is a top view of the railway car chair.

Like many railway car chairs, mine is furnished with a reversible back, that is one, which can be turned over from front to rear of the bottom or seat part ofthe chair, or from rear to front thereof, in order that a sitter may face either in one direction or the opposite as circumstances or convenience may require.

In the drawings A, represents the reversible back; B, the seat of the chair; and C, C, the sup-porting frame or armrest standards which are affixed to the floor and connected by a cross bar D, arranged below the seat as seen in .Fig. 3. Vith this seat B, or with it and the reversible back A, are combined two foot rests E, F, by mechanism to be hereinafter described.

Each foot rest is supported by the lower legs of two levers G, G; G, G, which turn on fulcra or pins projecting from the inner sides of the standards, C, C, such pins or fulcra being shown by dotted lines at a, a, in, Figs. 1, and 3. These levers also serve to support'the seat B, and by means of round pins or journals 6, extended from-the opposite sides of the seat and into the levers in the positions shown by dotted lines in Fig. 3. 1

Fig. 6, is a side view of one of the levers G, and exhibits the pin holes and fulcrum hole thereof. Each of these levers, in advance of its fulcrum, is jointed to one of two rocker levers or lever frames H, each of which is arranged and made to turn upon a fulcrum c, as shown in Figs. 2, and 3, such fulcrum being extended from the standard C, within and against which such lever is placed. Above the fulcrum, each rocker lever H, is jointed to one of two connecting links or bars I, I, which are also jointed to opposite edges of and at the middle of the reversible back A. Each corner of the seat B, is furnished with a round projection (Z, to enter a corresponding socket piece 6, fixed to the reversible back, there being one of the said socket pieces at each corner thereof, as shown in the drawings. By means of such devices, the back may be connected with the seat or readily disconnect-ed therefrom as circumstances may require, such connect-ions operating in other respects as hinges, so that while ,a person is sitting upon the seat and throws or forces his body against the back, he may incline the back and at the same time move the seat forward and elevate the foot rest, thus imparting to the back, seat and foot rest of the chair, recumbent or convenient positions for the re pose or ease of the sitter. While the back is being pressed backward, the lever frames H, H, will be turned on their fulcra so as to throw forward, or in one direction, the lower legs of all the levers G, G; G, G. In consequence of this, both of the foot rests will be moved forward or in one direction, at one and the same time. By this moving forward the rearmost foot rest it will be carried more out of the way of the feet of a sitter, who may be in a chair that may be arranged in rear of the chair to which the said foot rest may belong.

Each foot rest consists of two boards 7", and g, one being hinged to the other at or near two of their edges and so applied or made with respect to the other as to be capable of being turned down into a right angle or thereabout with it and held in such position by abutting against'it or a suit-able stop. .The part 9, at or near the middle or each end of it has journals h, it, projecting from it and turning in the two adjacent levers G,. G. At some distance below each of the said journals, each of the said levers is furnished with a projection or stop 2', against which the back board 9, of the foot rest abuts, or is estopped when turned so as to bring the front board either in' front or in rear of it. The sectional view, Fig. 3, not only represents one foot board as turned down in a position to receive the feet of a sitter, but shows the other foot board as reversed or turned over. By such a construction of each foot board, it may be turned over or reversed so as to bring its foot rest 7", when underneath the bottom of the chair more out of the way,of a sitter in rear of the chair, than would be the case, were it not constructed so as to be reversible as described.

The reversible back A, I make in three parts is, Z, m, the two parts is, and m, being what may be termed head rests and so applied to the middle part Z, as to be capable of being moved toward or from the same, that is to say, each part is, or m, is supported by two sliders n, n, which slide into the middle part Z, and have arranged between and against them, two helical springs 0, 0, as shown in Fig. 4. The sliders move in opposite directions through the middle part, Z, so that while either head rest is supported by the seat of the chair or by its latches, it will support the springs and the other head rest bearing upon them. These springs serve for both head rests and to elevate the uppermost head rest to such a height above the middle part Z, as may be most convenient for the support of the head of a sitter. Each head rest, is provided with two or any other suitable number of latches p, p, for holding it in position at such distance from the middle part Z, as occasion may require,

such latches being operated by a thumb lever 1', or, .9, arranged on one edge of the middle piece, Z, and connected with the latches by suitable connections or rods, t, t, t, as shown in Fig. 4. The latches operate with notches u, u, u, made in the sliders.

From the above, it will be perceived, that the upper head rest may be lowered down below the neck of a sitter or it may be elevated to a suitable height to give support to his head; also, that in whatever direction, the back may be turned, that is whether it may be made to rest on the front or the rear of the seat, one head rest will be above the part Z, and the other below it, the lowermost head rest under such circumstances contributing with the part Z, to support the back of the sitter.

- The act of forcing rearward or inclining the back of the chair, at the same time, will cause the front foot rest to be elevated.

I am aware, that it is not new to make a recumbent chair in such manner, that the back, when moved rearward shall throw up an apron or foot rest, such having been accomplished by applying the foot rest to two leversand connecting the said levers to the back: by jointed arm rests such being represented in the patent granted by the Government of the United States to J. G. Holmes September 24th, 1844.

My mode or mechanism for effecting the elevation of the foot rests by the rearward movement of the back of the chair differs from others asabove set forth, inasmuch as its two foot rest levers G, G, are connected with the connecting bars I, I, by two inter.- vening rocker levers H, H, such levers, as shown in the drawings, being equivalent to what are usually termed tri-armed levers, as they are intended to operate all four of the levers G, G, G, G, of the two foot rests at one and the same time as above described.

What I claim is 1. An improved railway chair or combination of a stationary seat, a reversible back, two swinging foot rests and mechanism so connecting the said foot rests and the reversible back, as to enable the foot rests to be operated by the back in manner and under circumstances substantially as described.

2. I also claim making the reversible back A, in three parts 70, Z, m, arranged and applied together snbstantially in manner and so as to operate as specified.

3. I also claim the application of the springs to the head rest-s in the manner set forth, such head rests being provided with latches or their equivalents as specified.

In testimony whereof I have hereunto set my signature this 30th day of November DAVID BUZZELL. Witnesses:
