JOHN ODONNELL, OF MARSHALL, TEXAS.
SPARK-ARRESTER.
SPECIFICATION formingpart of Letters Patent No. 516,940, dated March 20, 1894.
' Application filed December 18,1893. Serial 110.493,!)94. (No model.)
T0 at whom it may concern:
Be it known that I, J OHN ODONNELL, of Marshall, in the county of Harrison and State of Texas, have invented certain new and useful Improvements in Spark-Arresters; and I do hereby declare that the following is a full, clear, and exact descriptionof the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
This invention relates to certain improvements in spark arresters for locomotives.
The object of the invention is to provide a spark arrester, exceedingly simple and durable in construction and composed of a minimum number of parts and which will remove arrested sparks to the fire box of the locomotive and will preventlive sparks being thrown out by the locomotive and thereby endanger property adjoining the railroad tracks.
The invention consists in certain novel features of constructions and in combination of parts more fully and particularly pointed out hereinafter and illustrated in the drawings.
Referring to the accompanying drawings:- Figure 1, is a side view of alocomotive shown diagrammatically with my invention applied thereto. Fig. 2, is a vertical cross sectional view of the front portion of the locomotive. Fig. 3, is an end view of the locomotive looking at the rear end thereof.
In the drawings the reference letter a, indicates the fire box of the locomotive provided with the door b.
0, indicates the smoke box at the front end I lower ends through openings 9 and h, respectively.
'11, indicates a forwardly facing funnel locatedbeneath the front end of the locomotive. An air pipe 3', extends upwardly from said forwardly facing mouth or funnel through the smoke box to the lower end of the smoke stack where it is provided with a T, or two horizontal tubes or branches is, opening or discharging through the openings g, into the lower ends of the spark chambers e. The constant discharge of air through the pipe is, caused by the forward movement of the locomotive causes a downward suction in the spark chambers and pipes f, thereby drawing the sparks and gas, &c.,'into said chambers and forcing them into the fire box through pipes f, where the sparks are thoroughly consumed with what gas and smoke may pass into the fire box.
A vertical series of air chambers Z, m, n, is located centrally and longitudinally within the smoke stack d. These air chambers can be formed by vertical pipes suitably joined together and perforated to permit air to flow into the annular space around them to prevent the stack choking. Each air chamber or pipe is provided with an annular upwardly inclined flange at its upper end forming a lateral deflector to throw the sparks and cinders laterally against the inner side of the stack and thereby break their upward force. The lateral flange or deflector q, of the upper central air chamber throws the sparks laterally to the openings h, into the upper ends of the spark chambers, said flange q, or deflector being located opposite said openings h, so as to throw the sparks and cinders into the spark or cinder chambers. A coiled perforated steam pipe 0, is located above said air chamber n, to throw dry steam onto the cinders that may pass upwardly above the opening 71, so as to thoroughly extinguish said cinders before passing out of the smoke stack. Said coiled pipe 0, is supplied with steam by means of pipe 19, extending from the'boiler through the smoke stack to said front end.
It is evident that various changes might be made in the forms, constructions and arrangements of parts described'without departing from the spirit and scope of my invention.
Having thus fully described my invention,
whatI claim as new, and desire to secure by Letters Patent of the United States, is
1. In a spark arrester, the combination of the smoke stack, the spark chambers on opposite sides thereof and extending through out the greater portion of the length thereof and opening thereinto at or near their opposite ends, conduits from the lower ends thereof extending downwardly and rearwardly and opening into the rear end of the fire box, and blast pipes located and opening into said chambers, as and for the purpose set forth.
2. The combination of a smoke stack, the spark cylinders longitudinally located on opposite sides thereof and opening thereinto, conduits from said spark chambers to the fire box, a blast pipe extending up in the stack and provided with branches arranged opposite and discharging into said chambers at said openings, a funnel located at the exterior of the locomotive and having a pipe extending to said blast pipe, as and for the purpose set forth.
3. In a smoke stack, the combination of the stack proper, the spark chambers arranged longitudinally thereon and terminating at their lower ends in discharges, each chamber opening at its upper and lower portions into the interior of the stack, annular deflectors arranged concentrically within the stack to direct the sparks toward said opening, and the air pipe entering the stack and having the funnel at its outer end and the branch discharges in the stack arranged to discharge into the lower portions of said chambers, sub stantially as described.
4. A smoke stack having the verticalseries of perforated pipe sections arranged concentrically therein with the upwardly and outwardly inclined flanges, the spark chambers on the exterior of the stack having the openings into the interior of the stack, a blast pipe in the stack having the discharge openings opposite said openings into the said chambers, substantially as described.
5. A smoke stack having the vertical concentric chamber therein open at the top and perforated and having the exterior deflecting flanges, spark chambers on the exterior of the stack having discharges and at their upper portions opening into the upper portion of the stack so that said flanges throw the sparks outwardly, the steam pipe above said concentric chamber and openings as setforth, the forwardly facing funnel at the exterior of the locomotive having the air pipe extending into said chamber, and havinglateral branches discharging into the lower portions of said spark chambers, substantially as described.
In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses.
JOHN ODONNELL. Witnesses:
W. L. MARTIN, J. O. ALFORD.
