SPARK-ARRESTER.

Specification of Letters Patent.

Patented au aiaisie.

Application filed September 3, 1912. Serial No. 718,374.

T 0 all whom it may concern Be it known that I, GUSTAV Gross, doctor of philosophy, chemist, a subject of the German Emperor, and resident of Breslau, Silesia, Germany, have invented new and useful Improvements in Spark-Arresters, of which the following is a specification.

My invention relates to improvements in spark arresters, and it consists in the constructions and combinations herein described and claimed.

The object of my invention is to provide an improved spark arrester, especially adapted for use with locomotives, which will act effectively to separate all heavy matters, such as sparks and cinders from the flue gases.

In the accompanying drawings forming a part of this application in which similar reference symbols indicate corresponding parts in the several views :--Figure 1 is a vertical axial section, illustrating one embodiment of my invention; and Fig. 2 is a section on the line AA of Fig. 1.

Referring to the drawings, 7) indicates a vertical cylindrical flue for receiving the gaseous products of combustion from a chamber, such as the smoke box a of a locomotive; said flue bein provided with a flaring discharge end 5 A cylindrical core 70 is supported by brackets 77 axially within the flue b and terminates in a flaring upper head within the flaring discharge end of said flue; said core being provided with a tapered lower end within the entrance end of the flue.

A hollow ring 2' is supported at the entrance end of the flue Z) and provided with an annular series of nozzles about the adja cent tapered end of the central core a; said nozzles being inclined to the axis of the flue for directing jets of fluid spirally through the latter. A suitable fluid, such as steam or compressed air, is applied under pressure to the hollow jet ring 2' by a pipe it. A pair of pipes c are shown discharging spirally within the flue b for directing additional fluid jets with a whirling motion through the air.

An outer casing, comprising inclined walls (Z and (Z and the lower cylindrical.

wall, is supported about the flue b to provide an outer chamber for receiving the heavy sparks and cinders separated from the flue gases; said casing being provided with a discharging cylindrical conduit 79 which extends concentrically within the flaring discharge end of the flue 6 at a point above the central core is. A plate 6 is secured spirally on the walls of said outer chamber for directing the sparks and cinders deposited thereon into the lower cylindrical portion f of said chamber; said plate being of less width than the outer chamber to provide a space 6 about the flue, for permitting a whirling action of the gases.

A discharge spout g for the cinders leads from the lower end of the spiral plate 6, to provide convenient means for discharging the cinders at any desired point.

From the above description, it will be clear that my invention provides a simple and compact construction adapted to efficiently separate all sparks and heavy matters from the flue gases, without interfering with the draft of the latter.

I have illustrated and described preferred and satisfactory constructions, but changes could be made within the spirit and scope of my invention.

I claim 1. In a spark arrester, the combination of a cylindrical fine provided with a flaring discharge end, a central core extending axially therethrough, means for directing jets of fluid spirally through said flue, a casing supported about said flue to provide an outer chamber, and a cylindrical discharge conduit extending from said casing concentrically within the flaring end of said flue. 2. In a spark arrester, the combination of a cylindrical flue provided with a flaring discharge end, a central core extending axially through said flue and provided with a flaring head within the flaring discharge end of the latter, means for directing jets of fluid spirally through said flue, a casing supported about said flue to provide an outer chamber, and a cylindrical discharge conduit extending from said casing concentrically within the flaring end of said flue and terminating above said central core.

3. In a spark arrester, the combination of a cylindrical flue provided with a flaring discharge end, a central core extending axially thercthrough, means for directing jets of fluid spirally through said flue, a casing supported about said flue to provide an outer chamber, a cylindrical discharge conduit extending from said casing concentrically within the flaring end of said flue,

and a spiral plate supported Within such outer chamber and extending across a portion only of the Width of the latter.

i. In a spark arrester, the combination of a cylindrical flue provided With a flaring discharge end, a central core extending aXi ally through said flue and provided With a tapered end Within the entrance end of the latter, an annular series of inclined nozzles surrounding suchtapered eore end,a casing supported about said flue to provide an outer chamber, and a cylindrical discharge conduit extendingfroin said casing coneentrically Within the flaring end of said fine.

In testimony that 1 claim the foregoing 1 my invention, 1 have signed my name in presence of two Witnesses, this twentythird day of August 1912.

GUSTAV GROSS.
