UNTTE STATES IVILLIAM MEIER, OF NEYVARK, NEW' JERSEY.

SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 318,573, dated May 26, 1885.

Application filed June 5, 1584.

To (tZZ whom it may concern.-

Be it known that I, XVILLIAM MEIER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and usefullmprovements in Spark-Arresters; and I do hereby declare the following to be a full, clear,and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide an improved device whereby the sparks are effectually prevented from passing out of the smoke-stack of a locomotive or other engine, by the appliances hereinafter described, without obstructing the draft.

The invention consists in the arrangement and construction of the several parts of my invention, substantially as illustrated in the drawing and described and finally claimed hereinafter.

The figure in the accompanying drawing is a vertical section taken centrally through the forward part of a locomotive, showing the relation of my improvement to the various parts thereof.

In carrying out my invention I extend or enlarge the smokebox or that part of the locomotive forward of the dues, so as to provide space enough for the proper arrangement of my device; yet, by reducing the parts, it may be used in locomotives as ordinarily con structed.

As illustrated in the drawing, A are the tubes or does of the boiler, and B the exhaust tube, constructed as ordinarily used. From the exhaust-tube or the end of the boiler, and extending at angle forward, being secured to the top of the shell 0 of the engine or in any suitable manner, is a perforated plate,D,forming a trap. In the construction shown in the drawing a plate, H, is used to close the back of the chamber or pocket above the perforated plate.

E is a deflecting-plate, secured, preferably, to the shell of the locomotive at the bottom,

(N0 model.)

and inclined at an angle upward and away from the boiler toward the perforated plate, leaving an opening between communicating with the chamber or pocket F. As will be understood, the plates E, D, and H extend from side to side of the shell.

G is a conveyer or tube communicating with the pocket F and provided with valve therein, whereby the (lead sparks are removed from the pocket 13 at stated intervals.

The exhaust mechanism is similar to thatiu common use.

The operation of the spark-arresting mechanism is as follows: The gases, &c., from the furnace passthrough the tubes A, as indicated by the arrows, and by the force of the draft are carried against the plate E and deflected thereby through the perforated plate, whence they pass into the atmosphere through the smoke-stack. The live sparks and cinders do not pass through the perforations, but rebound and fall behind the plate E into the pocket F, where they are extinguished, because of the vacuum or partial vacuum maintained therein, and, collecting, are removed at intervals through the conveyer G, falling upon the track or in a suitably-prepared place. The plate E, being placed at a distance from the ends of the fines in the boiler and inclining upward and away therefrom, does not break or obstruct the draft in the least, but serves to direct it in the proper direction through the perforated plate and smoke-stack. The cinders, being behind the plate, are away from the influence of the draft, and do not, as occurs in some spark-arresters, keep constantly agitated and liable to clog and seriously impair the successful operation of the device.

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

The combination, with the smoke-box of an engine, of a spark-arrester consisting of a deflecting-plate, as E, extending from the bottom of said smoke-box'near the boiler-tubes, and inclining forward and upward toward the top of the smoke-box, dividing said box into two divisions connected over the top of said plate, and a perforated deflecting-plate, as D,

arranged betweenv the smoke-stack and said plate Einto the poeket F, substantiallyas set to deflecting-plate E, being secured to the top forth.

of the smoke-box forward of the smoke-stack, In testimonythat I claim the foregoing 1 and extending backward and downward tohave hereunto set my hand this 27th day of ward the boiler-tubes,which,t0gether with the May, 1884.

plate H, forms a pocket under the foot of the r W'ILLIAM MEIER. smoke-stack, said plate D being arranged at W'itnesses: an angle to the plate E adapted to direct the OLIVER DRAKE,

sparks deflected against the same by the said} F. F. CAMPBELL.
