SMOKE-BURNING FURNACE.

SPECIFICATION forming part of Letters Patent No. 437,219, dated September 30, 1890.

Application filed February 24, 1890- Serial No. 341,582. (No model.)

To all whom it may concern.-

Be it known that I, ORIEN B. MARTIN, a citizen of the United States, residing at Akron, inthe county of Summit and State of Ohio, have invented certain new and useful Improvements in Smoke-Burning Furnaces, of which the following, with the accompanying drawings, is a specification.

My invention relates to smoke-consuming furnaces. Its object is to provide improved means for consuming the smoke by combustion Within the furnace, and thus make a saving in the cost of fuel and avoid the annoyances incident upon allowing volumes of smoke to escape into the open air.

With this object in view my invention consists in the construction and combination of the furnace and accompanying apparatus de scribed and shown herein,and pointed out in the claims.

The drawing is a front elevation of myirnproved furnace, parts of the same being broken away to more clearly illustrate its construction.

Above the smoke-jacket, which I place at the front end of the boiler, I place a branched stack A. A flue B connects said stack with an exhaust fan or blower C, said flue B being so connected with the stack thatby changing the dampers K K the smoke will pass into the flue B and to the blower C from either side A or A of the yoke A. A diaphragm D divides the furnace vertically through its whole length. A fiue E leads from the blower O to the ash-pit on one side, and the flue E leads from said blower O to the ash-pit at the opposite side of the furnace. The blower-fan O is driven by the pulley c, as shown. At one side of the furnace is a bell-crank F, to the lower arm of which is secured the rod G. The upper arm of said bellcrank operates the rod H, which is attached to cranks k, k, and k, for the purpose of throwing the dampers K, K, and K.

In the operation of my invention the sides of the furnace are fired alternately. As shown in the drawings, the dampers are thrown for coaling the left-hand side of the furnace, the right-hand side of the furnace having therein a bed of coals. The smoke of the-left side of the furnace passes back under the boiler, then comes through the boiler-fines to the smoke stack or jacket at the front of the boiler, whence it passes through the flue B into the blower O, and is forced through the flue E to the right side of the furnace. Thence it passes back under the boiler, thence through the boiler-fines to the smoke-stack jacket, and thence through the right branch A" of the stack A.

When the coal in the left-hand side of the furnace is fully coked and it is desired to fire the right-hand side of the furnace, the dampers K, K, and I are thrown, so that the smoke will pass from the right side of the furnace into the flue B through the blower O, the flue E, and the branch A of the stack A.

The blower 0 must be run ata high enough speed to make a sufficient draft. Sufficient fresh air will enter the furnace through the ordinary channels to make perfect combustion.

The diaphragm D should be so constructed as that a portion of it may be removed to al low the taking off of the man-head of the boiler when it is desired to clean the boiler. Said flues E and E may enter either the ashpit or fire-box, as desired; but I prefer to have them enter the ash-pit, as shown.

What I claim as my invention is-- 1. A furnace divided vertically by a dia phragm into two divisions, in combination with a blower, a branched stack connected with the smoke-jacket of the furnace, a flue connecting said branched stack and blower, flues leading from said blower to the two divisions of the furnace, dampers so arranged as to direct the current from either division of the furnace through the blower to the opposite division of the furnace, and means for operatingsaid dampers,substantiallyasshown and described.

2. In a furnace, the furnace divided vertically by a diaphragm into two divisions, and a branched stack above the smoke-jacket of the furnace, thebranches of the stack communicating with the divisions of the furnaces, substantially as shown and described.

8. In a furnace, the furnace divided ver tically by a diaphragm into two divisions, a

branched stack the branches of which comin presence of two witnesses, this 9th day of mgiiicate with the divisions of the furnace, December, 1889. a ower, and dampers, all bein" so arran ed 3 w as that the products of combustion ma; be ORIEN MARIIN' 5 exhausted from either division of the furnace, Vitncsses:

substantially as specified. THOMAS HALE,

In testimony whereof I affix my signature, F. J. LIBIS.
