SPARK-ARREVSTER.
SPECIFICATION forming part of Letters Patent No. 422,586, dated March 4, 189(k).
Application filed January 6, i890. Serial No. 335,982. (No model) To a/ZZ whom t may concern:
Beit known that I, EDWARD B. Giens, a citizen` of the United States, residing at North Platte, in the county of Lincoln, State of Nebraska, have invented a certain new and useful Improvement in Spark-Arresters for Locomotives, of which the following is a full, clear, and exact description.
My invention relates to an improvementin that class of spark-arresters in which a baftieplate across the smokebox is combined with a perforated screen, andhas for its object to extinguish the sparks and effect subsequently a more thorough discharge thereof through the smoke-stack.
It consists in features of novelty, as hereinafter claimed'.
On the accompanying drawings, Figure l represents a longitudinal sectional .view of thesmokebox and adjacent part of the body of a locomotiveboiler fitted with my invention; Fig. 2, an end view of the smoke-box omitting the door, and Fig. 3 a detached view,
` to an enlarged scale,f a portion of the perforated screens forming part of myinvention, like letters of reference denotinglike parts in all the figures.
A represents the body, and B the tubes, broken away, of a locomotive-boiler having the flue-plate C, smoke-box D, smoke-stack E, blast-pipe F, and induction or petticoat pipe G, all of said parts being of the ordinary well-known types. To the flue-plate O, immediately above the top row of tubes B, is fixed the upper edge of a baffle-plate ct, which extends entirelyracross the smoke-box D, and.
preferably inclines downward and forward from its junction with the flue-plate C to a certain distance, whence itis directed downward andA forward at a greater inclination by an adjustable portion toward its lower edge, which is adjusted to a suitable distance from the nue-plate C and bottom of the smokebox D.
To thebafe-plate d, preferably at the j unction of its two inclined portions, is secured the rear end of a horizontal screen b, which consists, preferably, of thin sheet-iron and extends entirely across the smoke-box D, and to a suitable distance forward, so as to leave a space or opening c between its front end and the front' end of the smolteebox D, as
shown. Through the screen b', over that portion only of its surface in front of the blastpipe YF, are formed vertical holes b', which are preferably of an oblong shape, and arranged as shown more particularly in Eig. 3, but may be of any other desired form and arrangement.
vAlong the front end of the perforated screen b is fixed the lower edge of asecond screen d, which extends therefrom entirely across the upper portion of the smoke-box D at a suitable inclination rearward toward the Snickestack E. Through this screen d over its entire surface are holes CZ, which may be of similar shape and arrangement to the holes ZJ of the screen t, or otherwise, as desired.
Opening from the blast-pipe F toward the front of the smoke-box D, are jet pipes or noz- Zles e, through which steam from the blast* pipe F passes into the lower and front por tions of the smoke-box D, beneath the screen b and in front of the inclined screen d, respectively.
By the above arrangement the incandescent sparks as they issue from the tubes B in front of the nue-plate C are diverted downward by the bafiie-plate a to the lower portion of the smoke-box D, beneath the screen b, where they are extinguished by the steam from the pipes e, and are partly carried off by the draft through the perforations b', the remainder being swept upward through the forward space or opening c into the upper forward portion of the smoke-box D, in front of the inclined screen d, through the holes d of which they are finally carried off by the draft through the smoke-stack E instead of accumulating in and obstructing the lower portion of the smoke-box D, as occurs with existing arrangements of this class.
By this invention a large area of perforated screen-surface being obtained, the effect of the steam-j ets e, combined with the draft from the blast-pipe F, enables the extinguished sparks to be carried off with the smoke more effectually than heretofore, thereby avoiding the necessity of frequent stoppages for cleaning out the smoke-box.
