IMPROVEMENT IN SMOKE AND CINDER CARS FOR RAILROADS.

Specification forming part of Letters Patent No. 122,601, dated January 9, 1872; antedated December 26, 1871.

invented a new and improved Smoke-Gar for Railroads; and I do herebyvdeclare that the following is a full and exact specification of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The object of this invention is to provide a means whereby the smoke, cinders, and exhaust steam will be confined in such manner as will prevent such annoyances from enten ing the car-windows, setting iire to property along the line of railway, and at the same time in nowise check the draught of the furnace in the locomotive. Numerous efforts have been made heretofore to accomplish this desirable result, but generally without success.

My invention consists in providing each train with a car immediately in the rear of the tender, or elsewhere, so constructed as to receive the exhaust steam and the products of combustion directly from the locomotive, confining them in such car wherein the steam and smoke will be partially condensed, the cinders falling to the bottom of the car, where they are quenched in water, the uncondensed steam and smoke nding exit through suitable openings made in the car for that purpose.

In the accompanying sheet of drawings, Figure l represents a side view of my invention, and Figs. 2 and 3 detailed views of deflector. l

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

The smoke, cinders, and steam are conveyed through the smokestack A and sectional tubes B and C to the open oriice F into the car E. The car E may be constructed of sheet metal or otherwise, and when in use is entirely closed at the top, ends, sides,and bottom, except that into either end, near the root', or in any other desirable place, are fit-ted the two orifices F and Gr and through the floor the outlet-pipes H and I. Now, it will be seen that as the smoke, cinders, and steam are discharged from the smoke-stack A, the current of air produced by the motion of the train will drive them into the mouth of the tubular section B,

(which is made funnelshaped at its front end for the purpose of catching the smoke and air5) thence it passes into and through the tube C, and nally through the orilice F into the smoke-car E. The cinders entering with the smoke will fall to the iloor of the car, where ythey may be quenched, if desired, by converting said rloor into a shallow tank filled with water, while most of the exhaust steam and smoke will probably be condensed, and that which remains will iind exit through the outlet pipes H and I. The ends of these out' let-pipes that protrude through the iioor of the car E are provided with swivel-turns or elbows, so that the escaping smoke, te., will be directed toward the rear of the train. The orifices F and G are each provided with a valve, so that in whichever way the car E is propelled the rear one ot' said oriiices will be closed and thus prevent the smoke, Ste., from passing directly through the car. The car E is provided with suitable man-holes through which to remove the accumulated cinders, Ste., when necessary. It will be seen by reference to the drawing, Fig. l, that the front end or bell-mouth of the tube section B is jointed in such manner as will admit of its being lowered or raised when passing under bridges crossing the track. This may be done in any desirable way, and I do not wish to limit myself to the manner shown in my model and drawing.

To insure the smoke, cinders, Snc., passing into the tubular passages, I place in the smoke-stack of the locomotive, near the top, a deiiector, J, (see Figs. 2 and 3,) which may be controlled from the cab of the engine by the engineer. In order to maintain and increase the draught the tubular section C, which passes over the tender, is also provided with a bell-mouth, b. If it shall be found advantageous to retain the smoke and steam in the smokecar E, to 'more certainly insure their being condensed, it may be accomplished by dividing said smoke-car into compartments with wire nettings, thus oii'ering obstruction to the steam and smoke and prevent their passing at once through the outlet-pipes into the open air. Although the car E is provided with two outlet-pipes, as shown in Fig. 1, yet it is intended to close the forward one of said outlets when the train is in motion, and allow the uncondensed steam and smoke to escape through the rear one only.

To insure the lowering of the funnel-mouth al when approaching a bridge crossing the track, a small obstruction, d, may be placed 011 a post or other suitable fixture, so that as the train approaches the bridge the supportf Will be brought in contact with said obstruction, `and said funnelmouth will drop by gravity to a level that will enable it to clear the bridge. The bridge being passed it Will again be raised to its proper eleva-tion by means of a rod leading into the cab, or by any other` desirable means.

Instead of having for the reception of the smoke, &c., a sepa-rate car, as shown at E, the same result may be obtained, if desirable, by constructing the tender in such manner as to perform all the functions of said car E.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. The car D E, for receiving and conning the smoke from the locomotive in the manner described, and provided with inlets and outlets, When said car is separate from the tender or other car, so that it can be placed at any part of the train and separately detached for repair or other purposes, substantially as herein described.

2. In combination with the above and with tubes 'B C leading thereto, the hinged tubesection a, and means for lowering it automatically, substantially as described, for the purpose specified.
