SPARK ARRESTER AND CONSUMER.

SPECIFICATION formingpart of Letters Patent No. 239,922, dated April 12, 1881.

Application filed September .13, 1880. (No model.)

To all whom it may concern:

Be it known that I, ALFREDBERNEY, a citizen of the United States, residing at Boston, in the county of'Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Spark Arresters and Consumers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom pan yin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

'15 My invention relates to spark and smoke arresters and consumers 5 and the object is to conduct the solid products of combustion that would escape from the ordinary stacks back to the fire-box or furnace, together with hot air and steam, so as to entirely consume them.

The invention consists in the construction and arrangement of parts, as will be more fully described hereinafter, reference being had to the accompanying drawings, in which- 2 5 Figure 1 is a longitudinal section of a locomotive-boiler with my improvements attached. Fig. 2 is an enlarged cross-section on' line 00 m. Fig. 3 is an enlarged cross-section on line 3 1 Fig. 4 is an enlarged sectional view of the saddle. Fig. 5 is a modification of stack, with double heating-chamber around the entire inside of the stack.

In the drawings, Arepresents a-locomotiveboiler, having fire-box or furnace B, flues O,

3 5 and smoke-arch D, to which the stack E is secured. In the smoke-arch are arranged the exhaust-tips a and petticoat or lift pipe b, of ordinary construction.

The saddle F is provided with inclined pas- 0 sages H, which guide the sparks into the tubes G, and has also one or more air-chambers, K, for heating the air. A hole, 0, is cast in the saddle for admitting the air to the pipe at, which is connected to a chamber or receptacle, I, havinga branch-piece to connect with the pipe 0, that leads from the saddle to it. The chamber I is connected by a thimble, l, to the return-fines L, which extend into the furnace B, in which a hood or deflector, B, is arranged,

to guide the sparks and products down into additional steam-pipe, 122, having its lower end turned upward, may be arranged in the smokearch, to-be used for preventing smoke when the locomotive is standing still.

To the outer flan ge,f, of the saddle the outer I barrel of the stack is secured, while the inner barrel is riveted to the inner flange, g, and to said inner barrel the cone W is secured. The cone has two or more pipes, w, or vanes depending from it, by which the sparks are guided down through the annular chamber a to the saddle. Above the cone is the netting a, clamped between the flanges a of the stack. On the inner side of the outer barrel is cast or secured in any manner a piece of metal form- 7 5 ing an oblong cavity or space, h, which is provided at its upper end with an opening, 72-, over which may be secured a funnel, if desired, or a number of smaller perforations may be employed instead of one large opening. The space h connects with the opening in the saddle and the pipes below. If desired, the stack may be made double, as shown in Fig. 5, so as to form an annular heating-chamber for the air. The operation is as follows: A fire having been made in the furnace and steam generated sufficient to work the locomotive, a vacuum is formed by the exhaust-blast from the nozzles a, by which the sparks and other fine particles and products pass through the flue 0 red hot. These are forced up through and above the petticoat-pipe into the stack and against the cone W, from where they are thrown down into the annular chamber, :andguided 5 by the inclines on the saddle into the pipes e and chamber I, from whence they are forced, by means of the steam from the pipe is, with the heated air entering through the cavity h, into the furnace through the flues L.

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

1. The method herein described of controlling and utilizing as fuel the sparks and unconsumed products of combustion,by combinin g a cone, an annular chamber in the stack, a saddle with inclines, connecting pipes with an enlarged chamber, and return-fines, through which the products are driven by a forced blast of heated air and steam, substantially as specified.

2. The method herein described of arresting the sparks and unconsumed products of combustion,consistin g in forcing them through the stack by blasts of steam against a cone or netting, which deflects them into an annular space in the stack, from where they are drawn and forced through a saddle and return-fines, by means of one or more combined heated-air and steam jets, into the furnace, substantially as specified.

3. In a spark-arrester, the combination of an air-cavity, with inlet and outlet arranged in the front part of the stack, with a saddleplate and return-fines, substantially as shown,

and herein described.

, 1 4. The combination, with an air-cavity iii the stack, connected to a saddle having a heatin g-chamber and pipes connecting with an enlarged chamber, into and through which the sparks and products of combustion are drawn and forced, by one or more jets of air and steam, through return-fines into the furnace, substantially as shown and specified.

5. The combination of a blower-pipe with stop-cock, an independent steam-pipe, and a return-flue to the fire-box, to be used to stop smoke from a furnace, substantialiy as speci fied.

In testimony whereof I affiX my signature in presence of two witnesses.

ALFRED BERNEY.
