LOGOMCTiVE-BOILER.

SPECIFICATION forming part of Letters Patent No. 557,459, aat-.ea March s1, 189e.

Application filed July 2, 1895. Serial No. 554,726. (No model.) 'i

To tu whom t may concern:

Be it known that I, WILLIAM B. WARREN,A

residing at the city of Peoria, county of Peoria, and State of Illinois, have invented a certain new and useful Improvement in Locomo-I tive-Boilers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The object of my invention is to provide a construction of exhaust-passages and smokestaeks which Will create a greater and more equal draft through the ues of the boiler, thereby saving fuel, and also providing a better spark-arrester by more equally distributing the draft across the smoke-arch.

,Figure I is a vertical section ofthe boiler, cnhaust-pipes, and smoke-stack through the line I I of Fig. II. Fig. II is a top or plan view of a portion of the boiler.

Referring to the drawings, l and 2 are the exhaust-pipes leadi'ug from the cylinders. I prefer to have them lcadinto a chamber S, as shown, from which diverge tiyo exhaust-passages land 4, f rming atI their point of convergence the delector It' These open into the smoke-arch 7, as shown.

5 and f5A are smoke-stacks, so situated as to be immediately above and coincident or in line with the exhaust-pipes 3 and I, said passage i discharging into stack 5 and said passage I into stack 6.

f) is a perforated screen at the bottoni of the smoke-arch and above the top line of the boiler-dues. 4 f

lO are nipples secured to the ends ot' the exhaust-pipes and fitting in the screen for holding the exhaust-passages in position in thescreen.

wedge-shaped part at i the steam is dividedand passes into the passages 3 and 4, which are located beneath the smoke-stacks 5 and G and which direct the steam through the smokearch into the smoke-stacks. -I thus create a draft through both stacks, which are located at' different points on the smokefarch, at each exhaust from the two cylinders, and this accomplishes the purpose of creating a greater and more equal draft or vacuum through all the dues than can be produced when exhausting steam into one smoke-stack, which was the case in the old system, thesingle exhaust tending to produce a draft only through the center flues and' not through the side and top lues, as is the case in my invention. Also by reason of thedividing of the steam and providing a plurality of exhaust-passages' therefor the back pressure of steam in vthe cylinders is reduced to a minimum.

The screen 0 serves as a spark-arrester, and the two smoke-stacks 5 and 6 may be inclosed in an outer covering, if. desired, to give it the appearance of a single stack'.

Having described my invention, I desire to secure by Letters Patent.-

l. Zlhecombination of a plurality of smoke stacks located in a line across thev top of the smoke-arch and on different arcs thereof, en

haust-pipes leading freni the steam-cylinders to a point directly under the smoke-stacks, a chamber with which su'ch exhaust-pipes communicate, and diverging exhaustpasf sages leading from said chamber to the smokestacks whereby the' exhaust-steam from each pipes leading from 'the cylinders to a chamber and exhaust-passages leading from said chamber to the smoke-arch and so arranged that each exhaust from the'cylinders Willqpass out into the smoke-arch and through Aboth .smoke-stacks and thereby cause adraft through all the boiler-dues, substantially as and for the purpose set forth.

3. The combination of a boiler,`tl1e plurality of smoke-stacks located in a line across the boiler-top and on different ares thereof, exhaust*i l pes leading from the steam-cylinso' cylinder will be directed through both of the s' ders io the boiler, :md a Chamber having dand smoke-stacks, subsmntallyzns shown and vel-glug exlmusl-pnssages loading therefrom described;
