CHARLES Ei. GEORGY AND MILLARID FILLIVGRE HAMILTN, 0F LEBANON, PENN- SYLVANIA.

SPARK-AR-RESTER.

Application filed July 29, 1914.

To all 107mm it may concern Be it known that we, CHARLns H. Gnoner and Minnann FiLLMonn HAMILTON, citizens of the United States, residing at Lebanon, in the county of Lebanon and State of rlennsylvania, have invented certain new and useful improvements in Spark-Arrestters, of which the following is a specification.

rlhe present invention has reference to spark arrester-s, and it proposes, briefly, a device of the general class or character specified which comprises a substantially annular perforated tube or pipe situated within the interior of the smoke stack directly above the damper and connected with a source of steam supply, whereby the jets of steam issuing from the perforations in the pipe impinge against the ascending sparks, cinders, soot and particles of carbon, with the result that they are arrested and caused to fall back into the combustion chamber, while, at the saine time, any live sparks or cinders are extinguished.

rl`he improvements wherein the invention resides relate primarily to the mounting of the attore-mentioned perforated tube, and to the connection of the steam-supply pipes thereto.

rin embodiment of the invention is illustrated in the accompanying drawing, in which Figures 1 and 2 are fragmental side elevations, taken at right angles to each other, of a smoke stack equipped with the improved spark arrester; and Fig. 3 is a transverse section.

ln said drawing, 1 indicates, generally, the stack of a locomotive or other engine, 2 the damper plate arranged therein, and 3 the rod for adjusting the damper.

The spark arrester is located within the said stack directly above the damper, as previously stated, and embodies a loopshaped, or substantially-annular pipe or tube l whose threaded terminals 5 pass through openings formed in the stack and in a pair of juxtaposed plates 6, the latter being bolted to the outer face of said stack. rllllie pipe l is disposed horizontally, as shown, and is formed along its inner surface with a longitudinal series of perforations 7 that are so arranged as to direct the jets of steam inwardly toward the center of the stack, as will be understood from Fig.

3, thereby causing the jets to intersect the ascending column of cinders, sparks, etc.

The pipe l is supplied with steam from the boiler by means of the piping system represented in Fig. 2, wherein the pipe section 8 leading from the boiler is shown as having one end threaded and fitted in one arm of coupling 9, the opposite arm of which receives one end of a pipe section 10 alining with pipe 8. The stem of this coupling receives one end of a short threaded section 11 that is fitted at its other end in an elbow 12, the latter having also connected to it one end of a second threaded section 13 whose other end is connected to a sleeve or tting 14,-, and to the said sleeve is attached a third threaded section 15. The last-named section. and the lower end of the pipe 10 are equipped with elbows 16 and 17 to which are also connected the projecting ends 5 of the jet pipe el. A

The operation is believed to be apparent from the foregoing, and, therefore, to require no further explanation, since it will be understood that the jets of steal i serve to prevent the sparks, cinders, etc., from passing above pipe l, and to extinguish the said sparks and the live cinders. By connecting the component members of the piping system to one another and to the jet pipe, all of such members may be readily coupled and uncoupled, thus enabling any injured part to be readily replaced. rJ'he jet pipe itself is supported by the passage of its terminals through the stack and the plates 6.

What is claimed is :M

rlhe combination, with a stack having a pair of juxtaposed openings, and a pair of plates secured to the exterior of the stack and having openings registering with the first-named openings; of a loop-shaped, perforated pipe arranged horizontally within said pipe and having its terminals projecting outwardly through said registering openings; and a pipe system for supplying steam to the perforated pipe embodying a pair of superposed vertical sections, a T- coupling connecting the confronting ends thereof, an elbow connecting one end of one of said sections and the adjacent projecting terminal of said perforated pipe, a lateral section connected to the stem of said coupling, an elbow connected to the outer end of said lateral section, a pair of superposed sections arranged opposite and in spaced, parallel relation to the first-named In testimony whereof We afl'x our signzln Vertical section aioreszud, one of the seoondtures 1n presence oi two wltnesses. named vertloal sections being connected to the lastnamed elbownnd the other of such i HI'IIOMM Ow 5 section to the other projecting terminal of F l L1 l' the perforated pipe, and a sleeve connecting Witnesses:

the confronting ends of the second-named WV. C. GRAEFF,
