LOCOMOTIVE.

SPECFICATION forming part of Letters Patent No. 359,947,6.ated March 22, 1887.

Application led October-25,1884. Serial No. 146,690. (No model.)

To all whom it may concern:

Be it known that I. CHARLES HENREY WIL- SON, a citizen of the United States, residing at Paducah, in the county of McCracken and State of Kentucky, have invented a new and useful Improvement in Locomotives, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in locomotives; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is partly a side elevation and partly a vertical central longitudinal sectional view of a locomotive with my improved devices attached thereto. Fig. 2 is a vertical sectional view of the same, taken on the line a; of Fig. l. Fig. 3 is a detailed view.

This improvement relates more particularly to locomotiveengines;` but it may be appliedto steam-boiler or other furnaces.

The object of the invention is to provide improved devices for arresting the sparks and to do away with the annoyance of smoke, soot, dust, 85e., and to increase the draft and de crease the consumption of fuel.

Referring by letter to the drawings, A designates the boiler ofthe locomotive, which is provided with the fire-box or furnace B, the grate C, the ash-pit D, ilues E, smoke-box F, and stack G, in the usual manner. In the smoke-box, directly facing the head of the boiler, is a hood, H, which forms an elbow or rearwardly-extending horizontal portion of a spark-funnel, l,whichis secured vertically in the smoke-box and extends downwardly below the lower side thereof for a suitable distance. The bottoni of the spark-funnel is formed by the pivoted balanced valve K, to the protruding ends of the shaft of which are secured levers L, that are weighted at theirlower ends, so as to keep the valve K normally in a horizontal position, closing the lower end of the sparkfunnel. A cord or rod, lll, is secured to the upper end of one of the levers L, and extends therefrom to the eab of the locomotive in easy reach of the engineer.

N represents pipes th at extend from the ashpit and enter the hood H, and have their ends turned downwardly therein, and O represents pipes that are connected to the steam-chests of the engines and conduct the exhaust-steam therefrom into the hood, as shown, the arrows which are not feathercdindicating the currents of exhaust-steam in the drawings.

l? represents a sleeve, which is placed on the end of the hood and is adapted to slide back and forth thereon.. Lugs R project from the outside of the hood, and similar lugs, S, project from the outer side of the sleeve, and to the lugs S are secured rods T, .that pass through eyes formed in the lugs lt. The sleeve is provided witli a funnel-shaped mouth, 1?', corresponding in size to nearly the diameter of the boiler. The sleeve is moved back and forth on the hood by means of a lever, U, fulcrumed in the front side of the smoke-box, and a rod, V, connecting one end of the lever with the sleeve, and an actuating-rod, V, that extends from the opposite end of the lever to the cab within easy reach of the engineer,who can thus cause the sleeve to close or enlarge the opening to the chimney, and thus regulate the draft.

The exhaust-steam from the pipes O forces the smoke, gases, so., which enter the hood from the boiler-lines and the sleeve through the pipes N into the ashpit beneath the grate. The smoke, gases, dsc., mingled with the eX- hauststeam are consumed by the re in the fire-box, creating astrong draft and au intense heat,.and enable slack coal or screenings or other cheap fuel to he used to make steam.

Among the advantages gained by my improved devices is that the two or three upper rows of boiler-fines will not become choked with soot, as is the case with the locomotives in common use, and, owing to the greatly-increased draft, steam can be madein plenty with very little labor. Vhen going downgrade, and on other occasions when steam is not needed to be supplied to the engines, the sleeve can be moved in against the head of the boiler, and thereby almost entirely cut off the draft, and thus effect a great economy in fuel. The sparks, cinders, and heavier products of conibustion will fall into the smokefunnel l, and be extinguished by the water resulting from condensation of a portion of the exhaust-steam. Vhen a sufficient quantity of extinguished sparks and cinders have accumulated in the IOO in the smoke-box and having the movable sleeve I), for regulating the draft, the exhaustpipes O, extending into the hood, and the pipes N, leading from the hood to the ash-pit, for the purposes described, substantial] y as set forth.

3. The combination of the spark funnel or receiver I, located in thesmoke-boiz and having `the hood Hv and the tilting bottom or valve,

with the exhaust-pipes O, extending `into the f hood, and the pipes N, leading from the hood' to the `ash-pit,` substantially as described@I 4. The combination of the spark funnel or receiver I, located in the smoke-box andhaving a bottom or valveadaptedlto dischargeits contents, and the hoodiH, withthe exhaust-` pipes O, extending into the hood, the pipes N,

leading from the hood to the ash-pitfthe sleeve l?, sliding on the hood and having thelfunnelshaped mouth, and means for moving the sleevei to regulate the draft,substantial1y as described.`

In testimony that I claim the foregoing as my own I have hereto affixed niysignature in presence of two witnesses.

HARLES `HEYREY WILSON.`
