THEODORE J. HAWKINS, OF JAMESVILLE, MISSOURI.
SPARK-AR'RESTER.
SPECIFICATION formingpart of Letters Patent No, 731,898, dated June 23, 1903.
Application filed April 11, 1903. Serial Nl152,231. (No model.)
of Missouri, have invented new and useful- Improvements in Spark-Arresters, of which the following is a specification. My invention relates tonew and useful improvements in spark-arrestersfor the stacks of locomotives, &c.; and its object is to provide a novel arrangement of screens whereby theoutward passage of sparks is retarded.
A furtherobjectis to provide means whereby incandescent particles which may escape through the screens are caught and held in such a position as to be thoroughly consumed prior to their discharge from the device.
Withthe above and other objects in view the invention consists in arranging a cap within the end of the smoke-stack, said cap being so supported therein as to permit the h products of combustion to escape there- 7 around, the passage between the cap and the I 7 sides of the stack being of such size that the cap willnot interfere with the draft. Arranged above the cap is a cylindrical screen having an inverted frusto-conical screen exa conical screen.
tending thereinto and inclosing an integral A screen-casing inclosesthe top of the stack and has a solid metal-cap hinged thereto which is preferably conical in form and is adapted to direct any incandescentparticles which may come into. contact 7 therewith downward intothe fr'usto-conical screen before referred to.
The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawing, which is a vertical section't-hrough a stack having my improved spark-arrester. in
position thereon.
Referring to said figure by numerals of reference, 1 is a stack having its upper end 2 enlarged, asshown, and within this end is a concavo-convex cap 3, which is supported in position at the center of the stack by means of arms 4, which are fastened in any suitable manner to the sides of the stack. A passage 5 is thus formed around cap 3, and
5 this passage is of such size as to permit the ;products of combustion to flow freely there- .drical screen-casin g through. Brackets 6 extend from opposite sides of the stack, and to one of these is hinged a ring 7, from which extends a cylin- 8, secured at its upper end to a ring 9. A conical solid metal cap fis'securedto the ring 9 and, together with the rings 7 and 9 and the casing 8, is adapted to be'swung laterally upon the hinge of the link 7 by means of a rod 11, which is pivoted to an arm 12, extending from said cap. An inner concentric ring 13 is arranged within ring 7 and is connected thereto in any suitable manner, as by means of rods 14:. EX- tending upward from this inner ring is a cylindrical screen-casing 15, having an inverted frusto-conical' screen 16, extending downward from the upper end thereof, and within this frusto-conical screen is a conical screen 17, arranged directly over cap 3 and extending upward from the lower screen 16.
It will be understood that when the products of combustion pass out of the stack through passage 5 the outward movement thereof will be retarded by screens 15 andl6 and the majority of the incandescent particles will be thoroughly consumed before escaping therethrough. Should any incandescent particles, however, pass through the screens 15 and 16, they would be brought so violently into contact with cap 10 as to be thrown downward into the bottom of the screen 16, where they would be held in the draft passing between rings 7 and 9 until thoroughly consumed.
In the foregoing description I have shown the'preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.
Having thus fully described the invention, what is claimed as new isp 1. In a spark-arrestenthe combination with a stack havinga centrally-arranged cap in the mouth thereof of concentric rings inclosing the stack and lindrical screens extending from the rings, a conical cap upon the outer screen, an inwardly-extending frusto-conical screen inedge of a tegral with the inner screen, and a conical screen extending upward from the lower edge of the frusto-conical screen.
2. In a spark-arrester, the combination with a stack having a cap centrally arranged in the outer end thereof; of concentric cylindrical screens inclosing said end and hinged to one side thereof, a conical cap secured to the outer cylindrical screen, a downwardly-extending frusto-conical screen integral with the inner cylindrical screen and projecting to a point above the cap in the stack, and a conical screen projecting upward from the lower edge of the frusto-oonical screen.
3. In a spark-arrester, the combination with a stack having a cap arranged in the outer end thereof and forming a passage there- THEODORE J. HAWKINS.
