JAMES V. HUBBER, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE- HALF TO ABE-AM ALTMAYER, OF SAME PLACE.
SMOKE CONSUh/HNG FURNACE.
SPECIFICATION forming part of Letters Patent No. 309,226, dated December 16, 1884.
Application filed October 3, 1884.
To a whom, it may concern.-
Be it known that I, JAMES W. I'IUBBER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Smoke-Oonsuming Engines or Furnaces, of which the follow ing is a specification.
The object of my invention is to provide a means whereby all or nearly all of the waste products of combustion-such as the smoke and cinders from the furnaces of steam-engines or locomotivesare withdrawn from the Smokestack or chimney and returned to the furnace again to be consumed. I accomplish this object by the means illustrated in the ac companing drawing, which is a, front elevation of my improved steam boiler furnace partly broken away.
A is an exhaust-pipe which enters the stack or chimneyjust above the coupling, with the man-hole at the top of the boiler. The pipe is bent, as shown, and extends upward in the stack or chimney to near the damper B, and is provided with downwardly-projecting tubes, air or smoke passages O, which extend from near the top of the pipe to the bend thereof in an irregular manner, as shown. From the stack the pipe A extends outwardly to an exhaust or forcing fan, D, to the inner side of which it is connected by a broad funnel-shaped tube, D. Underneath the fan-casing is constructed a chamber, E, which communicates with the fan-chamber and receives all of the smoke and products of combustion drawn from the smoke stack by the suction fan. From the chamber E a pipe, F, is connected, which passes down to near the floor of the ash-pit, at which point it is bent inward and enters the center of the furnace G, just beneath the firegrate. At the termination of this pipe is placed a rose or mushroom cap, H, provided with holes or openings, so as to distribute and give free outlets to the smoke and products of combustion into the distributingchamber under the fire-grate.
In order to provide for a more rapid discharge of the smoke and gases from the closed chamber under the grate-bars into the furnace above the fuel, I attach one or more curved pipes, I, at each side of the'furnace, one end (No model.)
of which enters the furnace below the gratebars, and extends upward and passes through the wall of the furnace above the grate-bars into the combustion-chamber, as shown. By this means, if the volume of smoke, gases, &c., received into the chamber beneath the gratebars through the forcing-pipe F be too great, the branch pipes at the sides of the furnace will give relief and carry off the surplus up and into the combustionchambeiz,
The operation will be as follows, to wit: The doors of the furnace and chamber beneath the grate-bars are closed air tight, or nearly so, and the fan set in motion, which draws the fumes, smoke, 850., from the furnace up into the short tubes or openings into the suction or inlet pipe, and on into the fanchamber beneath the fan. From thence it is forced on and down the outlet-pipe into the chamber beneath the grate, and up through the fire-grate and branch pipe into the furnace to be consumed. Thus it will be seen that a suction and forcing operation is continuously going on, and but little if any of the waste products of combustion-such as the cinders and smokeare allowed to escape through the smoke-stack, while a sufficient draft is constantly supplied to the fuel-chamher to promote and keep up combustion.
Having thus described myinvention, what I claim, and desire to secure by Letters Patent, 1s-
1. In a sinokeconsu min g engine or furnace, the inlet or suction pipe entering the smoke stack or chimney, and provided with downwardly-projecting holes or openings, and ter minating in a broad funnel connected to the fan-blower,substantially as described.
2. In a smoke-consuming furnace or engine, the exhaust-pipe A, having inlets (l at the end which entersthe smoke-stack, and terniinating at its other end in a funnel, D, in combination with the fan D, chamber E, and pipe F, having rose I-I, substantially as shown and described.
In testimony that I claim the foregoing I have hereunto set my hand and seal.
