ROBERT H. COLEMAN, OF CORNVALL, PENNSYLVANIA.
SPARK=ARRESTER.
SPECIFICATION forming part of Letters Patent N0. 387,624, dated August 14, 1888.
Application filed May 10, 1888. Serial No. 273,385.
To all whom it may concern:
Be it known that I, ROBERT H. COLEMAN, a citizen ofthe United States,residing at Gornwall, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements iu Spark-Arresters for Coal-Burning Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to spark-arresters for coal-burning locomotives or other engines, and has for its object an improvement in the construction of such devices, whereby the passage for the main draft is extended, the burning gases backed up in the tire-box and lines by cushioning them upon eddies formedin the smoke-box, the cinders or refuse of combustion disintegrated, extinguished, and depos. itcd in an extension of the smoke-box.
The invention will be hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, which form part of this specification, Figure l represents a vertical longitudinal section, and Fig. 2 is an end view, with the head of the extension to the smoke-box removed.
Reference being had to the drawings and the letters marked thereon, A indicates the boiler, which is provided with the usual fire tubes or lines, c, secured in the tube-sheet b.
B is the smoke-box, which is provided with a stack, O,and an eXhaustnozzle,D,iuto which both engines exhaust, or a separate nozzle for each engine may be provided. The exhaustnozzle supports a horizontal nozzle-plate, c, having its ends secured to the walls of the smoke-box in the usual manner. The plate c is provided with flanges d @,to which the lower ends of the defiection'plate E and the channel-plate F are secured by suitable bolts or rivets. The dellectiouplate E is secured to the tubesheet Z) a suitable distance above the fines, and extends at an angle to the fiange d of the plate c. The channel-plate F crosses the smoke-box and its extension at an angle and terminates in a baffie-plate, G.
H is a deadplate secured to the ring g, and is also set at au angle to form an extensionpassage, I, between it and the channel-plate (No model.)
F, for the main draft of the gases from the furnace to the boiler.
The space between the upper end of the channel-plate and the wall of the extension of the smoke-box is closed by wire-gauze h, or by asheet of perforated metal, for arresting any sparks that have not been extinguished. The channelplate F may be provided with an opening covered by a section, i, of wire-gauze or perforated sheet metal, which admits of an escape of a portion of the incombustible gases from the furnace. The position and angle of the opening in the angle-plate are such that cinders emitted from the fiues are driven past it and on into the cinder-pit. This opening` may be increased or diminished in size, or its position changed to suit different constructions of ash-pits and to adapt it to other furnaces or boilers.
The baffle-plate G, it will be observed, projects out a considerable distance beyond the upper end of the dead-plate and directs the cinders down into the chamber formed by the extension of the smoke-box, which I have termed the cinder-pit.
The cinders are removed from the pit by means of an ejector, K,which is supplied with water from the boiler A through pipe 7c and valveZ at suitable intervals. the ejector is provided with a cover, m, swung upon a yoke, a, secured to the sides of the body of the ejector by suitable pivots, and the cover is held in place upon the nozzle of the ejector by a thumbscrew, o, which passes through the yoke n and engages with a boss, n,on the cover.
Variations may be made in the angles of the several plates shown without departing from the spirit of my invention, the principal object being to secure an extension of the pas sage for the main draft of the gases, and to produce eddies in the gases inthe smoke-box, against which the gases issuing from the fines are cushioned, producing counter-currents in the outer ends of the rines, backing up the heat and gases inthe fire-box andthe fines until 4the combustible gases are consumed.
The smoke-box is provided with hand-holes q and covers r, and the deadplate H is provided with an opening, s, and a removable cover, t, for obtaining access to the space between the tube-sheet and the dead-plate for The nozzle of 8O the removal of any foreign matter which may be deposited there.
The construction being substantially as described, the operation is as follows: The d rait of the furnace induced by the smokestack and the exhaust of the engines causes the gases, with some particles of solid refuse inatter, to be drawn through the {ire-tubes, which, upon issuing from the ends of the tubes,strile against the deileetioaplate E, are directed downward, and by their velocity strike against the dead-plate H and form eddies,as indicated by the arrows 1. These eddies form aeushion for the gases emitted from the tubes, produce counter-currents in the ends of the tubes, and back up the heat and the gases in the Iirebox and the tubes until the combustible material in the gasesis entirely consumed. Afterfornr ing the eddies in front of the dead-plate the gases and eomminuted particles of einder form a eircunilex current in passing through the passage I, between the ehannelplate Fand the dead-plate, and under the baille-plate G. In their passage some of the ineombustible gases pass 01T to the stack through the perforations in the wiregauze ,while the cinders are raised by the current and deilected by the plate G into the cinder-pit. The remaining gases then pass off through the wire-ganze h, while any live sparks are arrested by the meshes of the wire.
The method involved in myinvention forms subjeetmatter of another application for a patent, Serial No. 273,384, filed herewith.
Having thus fully described my invention, what I claim is 1. In a spark-arrester, the combination of a defleetioirplate between the tube-sheet and the exhaust-nozzle, a channel-plate, and a deadplate on the opposite side of the nozzle, substantially as described.
2. In a sparknrrester, the combination of a deiiectiolrplate between the tubesheet and the exhaustvnozzlc, a channel plate, a nozzle-plate between the defleetioirplate and the channel4 plate, a dead-plate, a baille-plate, and an extended passage formcd by the channel-plate and the dead-plate, substantially as described.
3. In a sparlearrester, the combination oi' a deileetionplate, a channel-plate, a dead-plate, a bal'lleplate, anda screen between the upper end of the ehannelplate and the wall of the sxnoke-box, substantially as described.
4. In a sparlearrester, the combination of a deileetion-plate,achannel-plate provided with a perforated section or wire screen, a dead plate, a contracted passage between the channel-plate and the dead-plate,a balleplate, and a screen between the upper end ol' the chan nel-plate and the wall et' the smoke'box, sul stantially as described.
In testimony whereof I. af'lx my signature in presence ol' two witnesses.
