SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 655,798, dated August 14, 1900.

t Application iled May 11, 1900. Serial No. 16,298. (No model.)

To all whom t may concern/.

Be it known that I, NVILLIAM REICHOW, a citizen of the United States, residing at Princeton, in the county of Millelacs and State of Minnesota, have invented certain new and useful Improvements in Spark Arresters; and I do hereby declare that the following is afull,clear,and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a simple, durable, and effective device to be used in connection with the smokestacks used on locomotives and all classes of boilers and furnances or wherever' a sparkarrester may be found necessary in providing means whereby the sparks and other elements of combustion will be conducted to and caught in a suitable receptacle, from whence such elements may be removed whenever required, thereby preventing the same from escaping and being deposited upon the surrounding objects.

The invention consists in a spark-arrester constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure l of the drawings is a sectional elevation of a spark-arrester constructed in accordance with my invention; Fig. 2, a side elevation thereof, showin g one of the slides in a raised position; Fig. 3, an end view showing the conoidal deflector and its connections with the casing; Fig. 4, a detail view in perspective of the conoidal deector.

In the accompanying drawings, A represents the casing of the spark-arrester, provided with a flaring top CL, the smoke-stack B being located centrally in the casing and its upper end retained in position by radial braces b, secured thereto and to the casing. The upper end of the smoke-stack `B is liaring, as shown at c, and extending down into this flaring extension and slightly below the base thereof is a conoidal defle'ctor C. This deflector C has a circumferential concavoconvex gutter D, and the deliector is held in its suspended position by radial braces d, as shown in Figs. 1 and 3 of the drawings. The braces d extend over the concavo-convex gutter D and are secured thereto, whereby said gutter is braced and strengthened, the outer ends of the braces having upwardly-extending feet e for securing them to the daring extension a, of the casing A. The lower end of the smoke-stack B extends down below the end of the casing A to form a collar, whereby the same may be connected to a stack of a furnace, boiler, Vor other smoke-conducting device, the lower end of the casing being slightly concave, as shown at f, to form a better support around the extended end of the smokestack. The concave bearing f extends entirely around the Vcircumference of the casing A, its greatestdepth being at a point'where it joins the wall of the coupling end of the stack B, thereby holding the spark-arrester in position upon the end of the smoke-pipe and against lateral or sidewise movement when the diameter of the smoke-pipe is greater than the diameter of the coupling end of the smoke-stack, thus preventing the spark-arrester from shifting its position from any cause when coupled to the smoke-pipe.

The casing A has openings g diametrically' opposite each other through which the products of combustion may be removed, said openings being retained closed by suitable slides E, which engage with guide-iianges h upon the sides of the openings.

The slides E have thumb-anges 'i at their upper ends for convenience in raising or lowering them and are slightly concave to correspond with the convexity of the casing A, the conoidal deflector C extending some distance down into the upper end of the smokestack B, by which aperfect means is provided for guiding the ascending products of combustion against the deiiecting-gutter D. The convex or dish shape of the gutter D prevents the products of combustion as they pass upward against the same from escaping through the space between the gutter and the side wall of the flaring extension d of the casing A.

A spark-arrester constructed as above described provides a very simple andeective device that can be manufactured at a comparatively small cost and which may be con@ nected with any smoke-stack or pipe, as circumstances require.

IOG

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A spark-arrester consisting of a easin g having openings through its sides and slides for closing the same, a central smoke-stack eX- tending int`o the casing, a eonoidal detieetor having a gutter-shaped rim at its base, the apex of the deeetor extending into the smoke'- staok and the lower end of the stack eXtending below the lower end of the casing to form a coupling-collar; and a concave circumferential bearing between the walls of the casing' and the walls of the coupling end of the smokestaek, substantially as and for the purpose set forth. y

In testimony that I claim the above I have hereunto subscribed my name in the presence of twowitnesses.
