CHARLES B. LOVELESS, OF VORTHINGTON, MINNESOTA.

SPARK ARRESTER AND CONSUMER.

SPECIFICATION forming part of Letters Patent No. 314,697, dated March 3l, 1885.

(No model.)

To @ZZ whom it may concer/vz Be it known that I, GHARLEs B. LovELEss, a citizen of the United States, residing at Worthington, in ,the county of\Nobles' and State of Minnesota, have invented certain new and useful Improvements in Spark Arresters and Consumers; and I do hereby declare that the following is a full, clear, and exact de,- scription of the same, reference being had to the annexed drawings, making a part of this specification,4 and to the letters and figures of reference marked thereon.

Figure l of the drawings is a side elevation of a locomotive with my smoke-stack connect ed thereto;` Fig. 2, a similar view on an enpartly broken away to show the conductingpipe communicating therewith and with the smoke-stack, Fig. 3, a sectional elevation of the smoke-stack and conducting-pipe, showing it connecting with the smoke-box at the front end of the boiler; Fig. 4, an under plan view ofthe hood which forms the top of the smoke-stack; Fig. 5, atop plan view of the upper end of the smoke-stack with the hood re moved; and Fig. 6, an under plan sectional view taken on line x x of Fig. 3.

The object of the present invention is to pro; vide simple and effective means whereby the gas, smoke, sparks, or cinders from alocomotive are conducted back to the lire-box thereof and consumed, thus preventing the sparks setting fire to `prairies or brush-wood along the line of the road, also preventing the smoke and cinders passing into the cars. f

The inventionV consists in the peculiarcon# struction of the smoke-stack, also providing it with an independent conducting-pipe communicating therewith and with the fire-box of the boiler, substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents my improved smoke stack communicating with the smoke-box B of the usual boiler, C. This boiler is of the kind ordinarily used in a locomotive-engine, and is provided at its rear y end with a 4fire-box, D.

Immediately under the grate of there-box D is a chamber, E, with which communicates opening, b, located directly opposite the fun- Y nel-shaped head G, and divided into two independent openings by a vertical partition, c, which also divides the funnel-shaped head, as shown in Figs. 3 and I5.

Upon the smoke-stack A is suitably supported a hood, H, provided with a perforated sheet-metal or wire-gauze screen, I. Thishood H is so connected to the stack Aas will allow of its moving horizontally thereon in the arc of a circle to bring it in the direction of the Wind.

The means which I consider the most convenient for supporting and connecting the hood H so that it will be selfadjusting for the purpose above described are as follows: The hood H is formed with a depending iange. d, which lits over the edge of the rim a, and also a similar ilange, e, fitting over the edge of the funnel-shaped head G, which is provided with two or more friction-rollers, f. A horizontal plate, K, of the hood H 'bears uponl the rollers f, thus enabling it to turn with comparatively little friction. The hood H is provided with a central Vrod or spindle, y, which turns with it, and is supported by diametrical braces 7i i, connected to the interior sides of the stack A, the lower one, as shown at i, forming a step for the reduced end of therrlod or spindle g to turn on. The hood H is provided with a concavo-conveX deiiecting-plate, L, the concave or dished form thereof more cffectually catching the smoke, sparks, or cinders as they pass up the stack and throwing them through the opening b into pipe F. The smoke, sparks, or cinders come in contact with a second deflecting-plate, M, arranged below the plate L,and rigidly secured to the rod or spindle g, so that it willA revolve with it and give the sparks or cinders a chute laterally andinto the opening b as they pass up the stack from the smoke-boxwill strike against the partition c and be driven down through the rpipe F, thus preventing its interference with the smoke, einders, or sparks as it passes down the other conduit or on the opposite side of the partition,this being especiallyvimportant when the wind is blowing in a direction at right angles to thedirection in which the train is moving. The v windas it passes through the meshes of the screen I into the hood H catches the smoke,

the plate M, and thus conveyed. through the opening klinto the pipe F, from whencethey are conducted to the chamber E under the fireboX B, vand there consumed; It will be seen that the entire volume-of smoke,gas, cinders, or sparks is thrown into the rear part of the hood of the smoke-stack, the wind being drawn in at the front thereof through the meshes of the screen, 'and not only-carries the smoke, gas, cinders, or sparks through the conductingepipeto the chamber under the fire-box at t-he rear of the boiler, but supplies the necessary oXygen to keep up the combustion, .a suction being thus created under the re-box at' one end of the conducting-pipe, while at the opposite end the smoke, sparks, or cinders are being forced through it by the action of the wind. Itshould be understood that the speed or motion of the engine or locomotive forces the wind into the hood of the smokestack, which conveys the sparks thrown by the exhaust-steam against the screen back against the rear portion of the hood and int the conducting-pipe leading to the fire-box, the sparks being thrown by each exhaust ot' the steam against the interior surface of the screen, the suction created in the pipe drawing everything through it to the fire-boX.

To more effectually consume the escaping products of combustion, I' provide the conducting-pipe F with a branch pipe, N, communicating therewith, and entering the rebox D some distance above thefuel, as shown in Fig. 2. Ihe portion of the pipe N entering the firebox may terminate in a Tabranch, Aa spiral coil, or in any other suitable form found most desirable, and is closed at its end or ends, and provided with perforations, the object thereof being to more effectually distribute the escaping `air mixed with gas and smoke which is unconsumed throughout the area of the fire-box above the dame, in order to .ignite and burn up the products of combusof combustion that would otherwise pass out of the smoke-stack through the meshes of the screen, the gas, smoke, cinders, or sparks as they pass up the stack A being deiiected against the plate L by means of the lower plate, M, the greater body of air which enters the cap or hood, H above the plate L or upon the outside thereof, as indicated by the arrow, passing down the conducting-pipe F, and by so doing creating a suction,which draws the products of combustion through the opening b, and carries them with it to the point of discharge, as hereinbefore described.

The products not drawn through the opening b and which pass above and over the plate L are carried by the incoming current of air down the pipe F, thus making provision for a complete conduction of the gases, smoke, cinf ders,` or sparks, as they pass up the smokestack to a point where they are consumed.

When the engine is not in motion,the draft and smoke may pass out at the top of the smoke-stack through the screen, provision being made under the fire-box to take in air to supply it when the engine is running backward or remaining stationary.

My'invention, although especially designed as an attachment to' locomotive-engines, may be applied to all classes of moving engines.

Having now fully described my invention,
