sPEoIF'IcATIoN forming part of Letters Patent No. veasso, dated December 22, 1903. Application filed May a, 1903. Serial to. 156,707. (No model.)

To all whom it mag concern:

Be it'knownthat' I, AUGUSTINE P. ZINK, a citizen of the United States, and a resident of Lorain,'in the county of-Lorain and State of Ohio, have invented a new and Improved Spark Arr-ester and Extinguisher-pf which the following is a full, clear, and exact description. 1 r

The object of the invention is to provide novel simple details of construction fora= spark arrester and extinguisher especially well adapted for c'oactionwith the draft-stack of a locomotive and which will effectively arrest all the sparks entering the stack and convey them into a suitable receptacle carried on' the locomotive, wherein they are extinguishedby water-held in'the receptacle and at proper intervals are automatically discharged from said receptacle, which when emptiedof its contents returns to normal position for renewed service.

The invention consists in the novel construction and combination of parts, as is hereirliafter described,and defined in the appended c aims.

Reference isto be had to the accompanying drawings, forming'a part of this specification, in which similar characters of reference indicate corresponding parts-in all the figures.

Fig. 2 is an enlarged front view of the engine smoke-stack and of the exterior portion of the spark-arrester carried thereon. Fig. 3 is a vertical transverse section of the smoke-stack and details of the improved spark-'arrester substantially-on the line '3 3 in Fig. 2. Fig. 4 is a sectional plan view of the stack substantially on the line 4 4 in Fig.

Fig. 7 is anflenlarged longitudinal sectional view of the preferred form of the spark-extinguishing device substantially on the line 7 7 in Fig; 8: Fig. 8 is a transverse sectional view substantially on the line 8 8 in Fig. 7. Fig.'9 is a vertical transverse sectionaliview ofa modified form of the sparkarre'ster on astack. Fig. 10 is an enlarged partly-sectional side view of a differentlyconstructed spark arrester and extinguisher,

and Fig. 11 is a side'view of alocomotive-engine having the sparkarrester and extin guisher represented in Figs. 9 and 10 mounted thereon.

The improvement is available for coactive service with the draft-stacks of locomotives, traction-engines, portable engines, and other steam-generators where it is desirable to M rest sparks that ordinarily escape from the draft-stack. The preferred use of the improvement is for the arrest and extinguishment of sparks that ordinarily escape from the draft-stack of a locomotive, and the novel device is herein shown as so applied and embodies the following'details of construction.

A indicates a locomotive-engine wherein an enforced draft is preferably employed that projects the unconsumed products of combustion into thedraft-stack and from which they escape in objectionable amount when the common arrester-is employed for their restraint. I

The draft-stack 6 is a coniform shell of suitable dimensions and for service is mounted and secured upon the front end of the boiler of the locomotive A over the smoke-box for the reception of the gases and heavier products of fuel combustion, as usual.

A hood7, of sheet metal, is provided, shaped as shown in Figs. 1 and 2 and having an oblate spheroidal form of a diameter that exceeds that of the upper end of the draft-stack 6, the lower portion of the hood merging into the upper end of an inverted coniform depending extension 7, the lower end of which Q in Fig. 2 that the lower end of the depending coniform extension 7 is thus heldannularly spaced from the wall of the stack 6 at a suitable point below the flaring upper end of the draft-stack. I

An escape-pipe, that may flare upward and outward slightly, as shown in Fig. 2, or be cylindrical, as represented in Figs. 6 and 9, is secured in a central opening in the top wall of the hood 7 and is rendered stable in position by an annular fillet a orother means.

A spark-receiver 10, preferably in cup form and having a downwardly-converging tubular extension or leg 1O centrally projected therefrom, may be held within and partially above the draft-stack 6 at the vertical axis of said stack by two sets of strut-braces l1 and 12, or the stanchions 8 and braces 12 may be employed for-holding the spark-receiver centered in the draft-stack, as indicated in Fig. 9.

The braces 11 when employed project diagonally inward and upward from the stanchions 8 and are secured to the upper part of the receiver 10, the braces 12 extending from the lower end of the leg 10 to have secured engagement with the draft-stack 6.

A funnel-shaped conductor-trough 13 is held concentrically spaced from the exterior of the draft-stack 6 and coniform hood extension 7 by an attachment of its lower portion uponthe exterior of the draft-stack, and it will be seen that a concaved channel b is formed as a bottom wall for the conductortrough 13, said bottom portion having an inclination from a horizontal plane.

It will be seen in Fig. 6 that the conductor trough 13 is extended upward sufficiently to have contact with the hood 7", and in Fig. 9 the hood extension 7 is extended down to merge into the channel I), either of these constructions effecting the same purpose.

A spout 14 extends from the lower end of the hollow portion of the depending leg 10, inclining outward and downward, the outer end thereof having communication with the concaved channel 6 through an opening 0 in the wall of the draftstack 6.

The opening 0 is formed in the stack-wall 6 opposite the lowest point in the inclined bottom channel I), and from the lower side of the latter a spark-conveying pipe 15 is downwardly extended to discharge into a receptacle 16'. As shown in Fig. 1, the receptacle 16 may be held to rock from a horizontal plane by its pivotal support on a bracketframe 17, that depends from the locomotive A, said receptacle being normally maintained level by a counterbalance d.

As best shown in Figs. 7 and 8, the weight 61 is mounted upon an arm d, extended from the receptacle 16, at the end thereof which is nearest to the pivot-support of said receptacle.

A spring-arm 18 depends from the boiler A of the locomotive andis provided with an open hook (1 that will arrest the arm (1 when the receptacle is empty, and the weight cl is permitted to rock it into a horizontal position, said arm being suitably inclined to permit a free rocking movement of the receptacle. There may be a water-supply pipe e, extended from another water-supply A, having a stop-valve e therein, said pipe 2 being extended to the frame 17 for support of its outer end and passing through the trunnioned end of one member of the frame 17 into the receptacle 16. On the inner end of the pipe e a valve 9 is mounted, said valve being controlled by the float d that is connected with the valve 6 by a rod (F. The float d is held from dropping too far by the braces 0Z that extend from the float-supporting rod d to the upper portions of the side walls of the receptacle 16, whereon these braces are secured by their extended ends.

It will be seen that the weight of the float d and the rod d hold the valve (2 closed while the receptacle 16 is empty or but partly filled with cinders from the spark-arresting device; but when asuflicient quantity of cinders is deposited in the receptacle to form a bed,which by the jolting of the engine raises the float, then the valve 8 will be opened to supply Water for quenching the sparks that have entered the receptacle 16.

In operation the force of exhaustion of the locomotive-engine projects the products of combustion up into the draft-stack 6, striking the outwardly and upwardly trending wall of the cup-like receiver 10 and thence passing outward into contact with the concave surface of the hood 7. The light gases and exhaust-steam mixed therewith pass upward and toward the center of the escape-pipe 9 over the upper edge of the receiver 10 and through said escape-pipe into the open air. The impact of cinders heavy and light on the curved wall of the hood 7 will arrest their outward passage and by their gravity the heavier products of combustion are caused to drop into the receiver 10 and thence pass down and out into the conveying-pipe 15 and ultimately be discharged therefrom into the receptacle 16. Furthermore, the sparks or cinders that from their weight fail to pass over the upper edge of the receiver 10 im pinge upon the concave side of the hood 7, fall down into the hood extension 7*, and from the latter pass down into the trough 13 and thence into the conveyer-pipe 15.

It will be seen that when an accumulation of the sparks conveyed from the spark-arrester exceeds the heft of the counterpoise cl said sparks, along with the Water that has extinguished the sparks, will be dumped by the tilting of the receptacle 16,whereupon the latter will resume a level condition, and the proper quantity of water will be automatically supplied thereto by the cooperative action of the float-controlled valve 6 as beforeexplained.

In Fig. 6 is shown a slightly-modified construction. As shown, the spark-conducting trough 13 is extended upward and outward, so as to have contact with the exterior of the hood 7", thus closing the annular space that intervenes said parts, as shown in Fig. 3. The braces 11 take the place of the stanchions 8 and braces 11, said braces 11 extending between the upper end of the stack 6 and ceiver 10. i

In Figs. and 11 the construction and application of another style of spark-arrester is shown. In thiscdevice a chamber 15 is formed or secured in the spark-conveying pipe. 15, that is positioned a suitable distance below the stack 16, and from the chamber the pipe 15 is extended to a point near the ground or road-bed of the railway. In the chamber 15 a pan 15 is supported horizontally beneath the inlet end of a steam or water pipe 19, that extends from the boiler.

at the rear under control of the engineer, and a small stream of water enters the pan, mixing with cinders that fall therein and from the pan are washed down the pipe for discharge at the lower end of the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A spark arrester and extinguisher, comprising a draft-stack, an oblate spheroidal hood held concentric with and exterior of the upper. end of said stack, a spark-receiver having a hollow leg and supported from the draft-stack, an escape-pipe above the receiver and on the hood, and means for conveying sparks from the hollow leg and hood to a spark-extinguisher.
