LOCOMOTIVE ASH-PAN.

SPECIFICATION forming part of Reissued Letters Patent No. 10,558, dated February 3, 18 35.

Original No. 302,915, dated August 5, 1881. Application for reissue filel October 7,1881.

0 atZZ whom it may concern:

Be it known that I, CHARLES M. LAKE, a citizen of the United States, residing at Jackson, county of Jackson, State of Michigan, have invented a new and useful Locomotive Ash-Pan, of which the following is a specification.

My invention consists in an improved apparatus to utilize the waste-steam from the cylinders, in preventing the contentsjof the ashpan from freezing, and in clearing the ash-pan of said contents. Other incidental objcctsappear in the description and claims, an important one of which is providing the exhaustports at the ends of the cylinder and their connecting-pipe with three-way cocks, for the purpose hereinafter appearing.

In the drawings, forming a part ofthis specification. Figure 1 is a side elevation of a locomotive-boiler with apparatus attached, parts being broken away; Fig. 2, a top view of the condenser-bottom to ash-pan; Fig. 3, a section of Fig. 2 on line 2 2 and a vertical broken section of the boiler-arch, with which the ash-' pan is connected; Fig. 4, a broken detail of Figs. 1 and 2, in section, enlarged; Fig. 5, a perspective view of the skeleton frame of the ash-pan; Fig. 6, aperspective ofthecondenserbottom to the ash-pan with parts broken away; Fig. 7, an end view of Fig. 8; Fig. 8, a side elevation of a cylinder enlarged, with connected parts broken away; Fig. 9, an enlarged top view of parts in Figs. 1 and 8; Fig. 10, an end view of the upper portion of theboiler in Fig. 1; Fig. 11, a check-valve, and Fig. 12 a section of pipe showing its location and use.

The boiler is illustratediu Fig. 1 at E, por tions being in dotted lines.

D is one of the cylinders, the other being on the opposite side, in the usual manner of locomotive-engines. The exhaust-ports e c on the under side of each end of the cylinder D are provided with three-way cocks s s, which cocks are extended laterally to ward the trucks, (trucks not here shown,) and are connected by a pipe, at (1, Figs. 7 and 9. These cocks s s have a passage or wayleading into the cylinder, another way leading into pipe a a, and another way, 2, termed a waste-port, leading out into the open air. The cocks s s are provided with suitable plugs, r r, for opening and closing the ways of the cocks. A pipe, ,9, connects the pipe a a with the steam-condenser A. The plugs r r are connected by an operatingrod, 2.

The object of the three-way cocks ss is explained as follows: When the plugs M", which I have passages in them adapting them for the 'into the three-way cocks s s and prevent its return. The pipe 8 connects the pipe at a with the steam-condenser A, said condenser being located, in Figs. 1 and 3, beneath the arch or fire-place R of the boiler E. When the steam is conveyed into the condenser A, it is converted into' water which keeps hot and prevents the contents from freezing in cold weather, and when thus used prevents visible exhaust-steam.

The skeleton ash-pan frame B is provided with a detachable bottom. A, said bottom being the condenser. (See Figs. 5and 6.) This condenser consists of a frame and an upper and lower inclosure, O P, bolted to said frame. In Fig. 6 the upper inclosure, O, is broken away, showing central supports,c 0. These supports are provided with notches e e, to admit the passage of steam and water all through the condenser. The steam-pipe s passes through the side wall of the skeleton frame B and enters the condenser A, one on each side from each cylinder, Fig. 2. Pipes a a are connected with pipes s s, and extend laterally therefrom over the front end of the condenser A. These pipes a a are provided with ports 0 c for the exit of steam therefrom in blowing the contents out of the ash-pan. This is done by turning the three-way plugs a at the juncture of pipes s a, Figs. 2 and 4, in a manner to shut the steam from entering the condenser and ad mitting it into pipes at a. The condenser is provided with a discharge-spout, b, terminating at a proper height to govern the desired amount of water in the condenser. Draftpipes 'v v are connected with the corners of the condenser and extend to the rear of the boilerfines and enter the smokebox in the usual manner. The pipe d, Figs. 1 and 2, is designed for connection with the exhaustpipes of a steam-propelled engine which operates the brakes in order to convey the exhaust-steam from said engine into the condenser. Thus all the exhaust-steam from the entire locomotive construction may beeonveyed to the same con denser. The brake-engine and its exhaust pipes are not here shown, the pipe d being ex- J tended upward and broken away. Near the front of the boiler, on top, is an indicator, F, connected with the boiler F by a heater-pipe, H. With this pipe and indicator are connected branch heater-pipes n n, leading from one cylinder to the other over the boiler, Figs. land 10, and connecting with pipes at a.

The pipes H nnear the indicator, Fig. 10, are provided with stop -cocks. When the Waste-ports 2 2 of the three-Way cocks are closed by the plugs r1", steam maybe circulated from the boiler through pipes H n a s, to prevent danger of freezing np.

By means oi'the indicator the engineer can tell from the oscillation of the hand that the exhaust-ports e e are open, as a greater circula tion of steam passes through the pipesn a when the plugs r r are turned to open the ports 6 6.

Having thus described my invention, what I claim as new is 1. The combination, with a cylinder and a pipe connecting the ports, provided with threeway cocks, suitable plugs in said cocks, and

check-valves, of a condenser located beneath the ash-pan, and a connecting-pipe for conveying the steam to said condenser, substantially as set forth.

2. The combination, with a cylinder having connecting-pipe between the ports, and provided with three-way cocks and suitable cock plugs, of an ash-pan frame, detachable condenser-bottom, and pipe for conveying the exhaust-steam to the condenser, substantially as set forth.

3. The combination of an ash-pan, a condenser beneath the pan, a cylinder or cylinders, pipes connecting the cylinder exhaustports with condenser, three-way cocks at said ports, and branch pipes for blowing outthe ash-pan, having at thejuncture ofthe branches and pipe threewvay plugs whereby steam may be let int'o'the branches or into the condenser, substantially as set forth.

4. The combination, with the cylinders,an

indicator, a pipe connecting the indicator with the boiler, and heater-pipes connecting the indicator with the cylinder exhaust-ports, of an ash-pan, condenser, and pipes connecting the exhaust-ports with the condenser, said ports provided with suit-able cocks and valves, all substantially as set forth.'

In testimony of the foregoing I have here 'unto subscribed my name in presence of two witnesses.
