SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 247,256, dated September 20, 1881.

Application filed February 28, 1881.

To all whom it may concern Be it known that we, WILLIAM KOWALSKI, residing at Brooklyn, in the county of Kings, State of New York, GEORGE A. GUNTHER, residing at Bath, Long Island, New York, and ISAAC S. MGGIEHAN, residing at Lafayette, county ofHndson, State of New Jersey, have invented anew and useful Improvementin Spark- Arresters for Locomotives, by which sparks can be arrested and the draft regulated, of which the following is a specification.

The object of our inventionis to find means by which sparks from the boiler of a locomo- Live may be prevented from reaching the air through the smoke-stack and at the same time to accomplish this result to impair in no manner the force of the draft, but by some contrivance so to regulate it that it can be increased or diminished at the option of the engineer.

- nre 1 is a central vertical longitudinal section of a locomotive on linea: at. Fig. 2 is a central vertical transverse section on line 3 3 Fig.3 is a section on the line a z. 7

Similar letters refer to similar parts throughout the drawings.

A is a diaphragmsheet or deflecting-plate, which is placed in a vertical position, and is parallel with the fronttube sheet, (indicated by H.)

B is a platform of sheet-iron, which extends from the tube-sheet above the top of the tubes to within one-third of the distance from the tube-sheet to the front of the extended smokebox K. In the platform B are two slots, F F, by means of which the deflecting-plate A may be either moved backward or forward, so as to increase or decrease the distance between it and the tube-sheet.

G is the exhaust-nozzle,which passes through the platform B.

(No model.)

Extending to the top of the fire-box, atan angle of sixty degrees, is a wire-netting, (indicated by 0,) which arrests all sparks that may have retained velocity 'sutficient to have carried them there.

In the base of the stack are openings D D, whereby air may be admitted in a sufficient quantity to retard the velocity of the exhauststeam, and thereby deaden the noise caused by the said exhaust.

E is a movable joint that may be moved up and down in the stack, by which the openings may be partly or entirely closed or opened, thereby regulating the draft.

H is the front tube-sheet.

The operation is as follows: After the sparks have left the tubes they goin the direction indicated by the arrows in Fig. 1, and, after striking the deflecting-plate A, are thrown downward, to be carried again to the platform B, against which they will strike and fall to the front end of the extended smoke-box K.

What we claim,and desire to secure by Letters Patent, is-

1. In alocomotivesmoke-stack,thecombination of a movable deflecting-sheet, A, attached to a platform of sheet-iron, B, and connected with a wire-net, O, constructed and arranged as hereinbefore set forth and described.

2. In a locomotive smoke-stack, the combination of the movable deflecting-sheet A, the wire net O, and platform B, with a smoke-stack having at its base a movable joint, E, and the openings 1), as and for the purposes described.
