SPARK-ARRESTER.
SPECIFICATION forming part of Letters Patent No. 544,629, dated August 13, 1895.-
- Application filed July 11, 1895. Serial No. 555,625. (No model.) 7 Q I To aZZ whom it may concern.-
Be it known that I, WILLIAM HOLMAN PHILLIPS, a citizen of the United States re,- siding at Perry, in the county of Balls and State of Missouri, have invented certain new and useful Improvements in Spark-Arresters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in spark-arresters for use on locomotives; apd it consists of certain novel features hereinafter described and claimed. v
Reference is had to .the accompanying drawings, in which the same parts are indicated by the same letters throughoutthe several views.
Figure 1 represents a side elevation of a portion of a locomotive fitted with my improved spark-arrester. Fig. 2 represents an end view of the device shown in Fig. 1, as seen from the left of thesaid figure. Fig. 3 represents a perspective viewshowing the upper end of the smoke-stack with the cylindrical screen andouter cylinder removed.-
Fig. t represents a side elevation of the domeshaped cylindrical screen used in my invention, and Fig. 5 represents aside elevation of the outer cylinder which incloses the lower portion of thecylindrical screen.
A represents, the exterior. of the ordinary locomotive -'boiler provided with a smokestack B of the same general nature'as that ordinarily in use, but provided with the sparkarresting attachments, which will be hereinafter more fully described. This smoke-stack consists of an inner funnel B and an outer funnel comprising the base portion B reaching only part of the way up on the inner funnel, and the cylindrical sleeve F, which fits down over the top of the base portion B .This outer funnel is separated from the inner funnel by the metal bars or ribs b, of which there are three or more, but preferably four, as shown in Fig. 3. Above the top of the inner funnel B are placed at a suitable distance therefrom a lower and coarsescreen O and an upper and finer screen D, which screens are at somedistance apart and are secured to the ribs b, while'theyare'themselves stiffened with cross-ribs c and d, respectively. The upper screen Dis convex from below so as to deflect laterally the finer'particles'of, solid matter that pass through the coarse screen 0, which is preferably a flat screen placed at right angles to the axis ofthev smoke-stack.
The cylindrical screen E is slipped over the ribs 19, and at its lower portion is still further spaced therefrom by means of the studs b projecting from the said ribs, whereby a greater annular space. is obtained between the inner funnel and the said cylindrical screen. The upper part ofthis cylindrical screen is made in the form of a dome-shaped cap E, hinged to the cylindrical part at e and fastened by meansof the latch and catch 6' and c as shown in Fig. 4. This hinged cap not only renders it possible to obtain access to the interior of the smoke-stack and so to clean out'the various screens from time to time, butit also enables the fireman to get a better draft whenstarting fires; but it would rarely be necessary to lift the cap for this purpose.
The cylindrical sleeve F-is fitted over the cylindrical screen E and is spaced at a sufficient distance from said screen to allow the smoke to rise in the annular space between thetwo.
The cinders which are caught in the annular space between the inner funnel B .and
the screen E-fall down into the annular space.
between the said'inner funnel and the outer funnel B and are directedeither through the passages Hjto the boxesK .or through the pipe M to the fire-box P. These passages H are controlled by dampers h, so that all of the cinders may be deflected into the pipe M. whendesired. Thecinders when they are allowed to pass through these passages H enter the boxes K, placed beneath the foot-board L. These boxes are provided with bottoms k,
hinged at k and provided with latches k for 5 holding the same closed when desired. It would generallybe preferable to leave these boxes open in damp weather, as shown-to the left in Fig. 2; butthey might be kept closed and .emptied periodically, if preferred. It
will thus be seen that the herein-described apparatus will prevent the escape of sparks or large particles ofsolid matter of any kind from the furnace, while the smaller particles that will be able to get through the various screens will be so small that they will cool rapidly on reaching the atmosphere and will do no injury.
\Vhile I have described my invention as applied to locomotives, it will be obvious that it can be applied to fixed or portable engines of any description.
It will be obvious that various modifications of the herein-described apparatus might be made which could be used without departing from the spirit of my invention.
Having thus described my invention, what I claim, and desire to secure by LettersPatent of the United States, is
