SPECIFICATION forming part of Letters Patent No. 359,640, dated March 22, 1887,

Serial No. 206,048. (No model.)

To all whom it may concern:

Be it known that I, CHESTER W. M. S ITH,

- will be proof against collisions and destruction by fire. I accomplish this object by the means illustrated in the accompanying drawings, in

Figure 1 is a side elevation of my railwaycar with parts broken away to show construction and interior of car. Fig. 2 is an end View of the same. Fig. 3 represents parts in section through car. Fig. 4 is a horizontal section of a portion of the car taken below the windows. In Fig. 5adifferent manner of joins ing end plates to side plates is shown.

Similar letters refer to similar parts th roughout the several views.

In constructing my safety railway car I have found it necessary that all the parts be made of iron or metal, and nothing be left for the devouring element of fire to consume or splinters or broken fragments to wound or maim the passengers therein when collision takes place; hence my safety car is constructed as nearly as possible of iron or metal, and the parts so disposed and arranged as to receive the shock from collision at the strongest and best-fortified points to oppose such contact successfully, as well as to resist the action of fire in case of accident.

Let A A represent the two plates which together form the sills of the car, and one of which, as A, is bent in the peculiar manner shown in cross-section, Fig. 3, to provide the lips or flanges A A to receive the side sheets or walls and floor of the car. B B are the plates that form the beams or girders, which are constructed in like manner as that of the sills, and one of which, as B, is provided with the lips or flanges 13 13*, to receive the upper ends of the side sheets and the edges of the roof-plate. These beams or girders are inverted and receive the upper ends of the side sheets or walls and the roof of the car. In

constructing these sills and beams or girders the outer plates are bent simply at a right angle, and the edges thereof form one half of the two lips or flanges which receive the side sheets, while the inner plates are bent to a right angle, after which the edge of each member is bent outward to a right angle and placed parallel with the outer plate, in which position the bent edges thereof form the inner half of the two lips or flanges of the sills and beams.

The floor G of my car is constructed of one sheet of rolled iron and extends beyond the body of the car at both ends, forming the platforms. This sheet is arranged between the two lips or bent plates forming the girders or beams, and the edges of saidfloor C may, if desired, be made to extend inward within the beams or girders, between their lips or flanges,

sufficiently far to touch the outer angle-plates I at or near the point where they are bent to a right angle, as above explained. This mode of construction may be adopted where greater strength is needed. In this position the floor is bolted between the lips or flanges, through and through,at suitable intervals of space from end to end of the car, by bolts or rivets D,as in I riveting boilerwplat-es.

The side sheets of my railway-car are composed of a single plate of rolled metal, E, suitable spaces, E Qaipgmnt out for windowsand ventilation. The upper and lower edges of these plates extend between the lips of the beams or girders, as shown, and said side plates and the inclosing-flanges of the beams are bolted or riveted, through and through, at suitable intervals of space, as in bolting or fastening thefloor. The lower edges of these side plates may rest upon the flooring-sheet at right angles when the latter is extended to the inner face of the sills. The ends of these side sheets, forming the side walls of the car, may be extended outward and wiped or bent around to form the ends of the car, as at F, with suitable spaces cut away ,to provide for the doors and end windows, in which case the outer ends of the inner angle-irons of the beams are extended so that the end plates will breast against and be held in position by foot and overhead inner angleirons; or these end pieces may be composed of separate curved plates and be bolted to the outside of side plates or walls of the cars. (Shown in Fig. 5.)

Good rolled iron, one-half inch in thickness,

will answer for the plates composing the lower beams or girders, and three-eighths or onehalf inch iron for the plates composing the upperbeams and floor and side plates or walls, while the roof may be composed of a thinner and lighter plate of metal.

The roof G is constructed of a single plate, and sprung or bent to form the desired curvature, and the edges are clamped between the inner lips, laps, or flanges formed by the plates composing the upper beams or girders, by the rivets or bolts D, bolted through and through, in the same manner as in uniting the side walls or plates and the floor, above described, while the ends of the roof-plate are rounded and extend over the platform, as shown. Suitable spaces are cut from the root for windows and ventilation before it is sprung or put in position.

The gables H of the car may be composed of separate pieces, cut to conform to the curve of the roof at the upper ends, and bolted to the inner face of the roof and the upper end of end plates of the car when the sheets of the side plates are bent around to form the ends of the car, as hereinbefore described; but when the end plates are composed of separate sheets these may be cut out to form and carry the gables or ends with them. Suitable letteringboards will be provided by the outer faces of the upper and outer angle-plates composing the upper beams or girders.

For supporting and strengthening the interior of the car, vertical or upright wooden or iron posts J are interposed along the sides between the window-openings. The upper and lower faces of the sills may be held in position by bolts, or the ends maybe mortised into the beams. By this means the body of the car will be relieved of the downward thrust or spring in practice, and means be provided for hanging and operating the windows of the car. These upright posts also serve as another important and valuable factor in lining the inte rior of my car, which lining consists of thin sheets of metal K,such as copper, brass, or other non-combustible materialwhich may have a surface of some dead color to take off the glare or dazzle, and also be suitably ornamented. These sheets are tacked or secured to the upright posts with tacks, nails, or screws with ornamented heads, and the sheets may extend across the interior face of the dome of the car, and be kept in position by fastening to the longitudinal flat bars L.

At suitable intervals of space along the i nterior of the car are connected the T-braces M, which latter may be constructed of some light material, such as galvanized or plated iron.

The body of my car rests upon the horizontal sleepers or beams N, constructed of wood or iron. To these beams are connected the trucks and brake-connections, and they will also support the extended ends of the iron U floor or platforms. A packing, such as cotton-duck or rubber, is employed where iron is opposed to or oined with iron, such as the joints and drill-holes for the bolts or rivets, to neutralize the jarring effect of such connections.

Having thus described the construction of the body and frame-work of my collision and fire-proof car, I will now proceed to describe the interior fittings.

The saloons, closets, and doors are constructed of light sheet-metal, suitably ornamented, and the partitions of the closets and saloons are connected to the body of the car byV or L angle-irons in the usual way. The seat-frames are composed of light metal, upholstered with some incombustible material. The outer ends of the seat'framcs are connected to and supported upon the upper faces of the lower sills, with the inner ends bolted to the iron flooring. In sleeping cars the frames composing the berths therein will be constructed of light metal, and be folded up within the casing of the car in the usual way.

The bedding will be prepared of materials made incombustible by saturation in such fireproof chemicals as are well known in the arts, and every effort made to guard against cremation of occupants in case the upsetting of furnaces or stoves in the car should take place.

It will thus be seen that but little,if any, material will be contained in or about the car for the devouring elements of fire to feed upon.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
