SPECIFICATION forming part of Letters Patent No. 388,885, dated September 4, 1888.

Application filed April 5, 1888. Serial No. 269,648. (No model.)

To all whom, it may concern.-

Be it known that I, FREDERICK LEAD- BEATER, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Smoke Consumers; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and use ful improvements in smoke-consuming furnaces; and it consists of the construction of devices and appliances, together with their combinations and arrangements, as more fully hereinafter described, and more particularly pointed out in the claim.

In the drawings illustrating my invention, submitted herewith, Figure 1 is a vertical longitudinal section of a furnace embodying my invention. Fig. 2 is a front elevation of the same. Fig. 3 is a detail view of one of the inlet-fines shown indotted lines in Fig. 2.

The great points to be secured in a so-called smoke-consumer, as is well known, is to supply a sufficient quantity of oxygen to the combustion-chamber to render the combus' tion of the gases perfect, and thereby, in reality, to prevent the formation of smoke, or to render its ignition complete. To accomplish these results in a most efficient and satisfactory manner, and at the same time by an economical device which may readily be applied to any ordinary furnace without injury and without undue waste of time, is the purpose of my invention.

I carry out my invention as follows:

A represents the combustion-chamber of a furnace; B, the grate. G is the front wall of the combustion chamber; 0 C the doors thereto. These parts may be of any ordinary construction.

Through the wall of the combustion-cham her, and preferably through the front wall, I introduce one or more does, D, communicating with the combustion-chamber, and also with an exterior air box or conduit, E, which leads, preferably, to the exterior of the furnace-roomas, for instance, through an ad jacent window, -Fso as conduct any desired supply of fresh air into the combustion-chamber.

Where a series of dues D are desired to conduct the air from the conduit into the combustionchamber, the inner end of the said conduit may be extended across the front of the furnace as a manifold, E, from which the individual flues D lead through the wall of the furnace and open into the combustionchamber. This arrangement admits the air upon the front of the fuel-bed. I prefer, also, to contract the inner ends of the fines, as shown at (I, so as to spread the admitted air in a sheet over the fuel-bed and more uniformly distribute the airthereupon, so as more readily to unite with the products of combustion and facilitate theircomplete consumption.

It will be convenient, also, to lead the supply-conduit so as to communicate with the fines above the door to the combustionchamher, and consequently it will be desirable to extend the fines through the wall at an angle downward, so as to discharge the air into proper proximity to the fuel-bed. I prefer, therefore, to construct the fines each with an elbow, as at d, the longer arm of the fine being extended at an obtuse angle to the shorter arm, the latter arm being located, preferably,

' in a horizontal direction to direct the air substantially straight upon the fuel-bed. The angular direction of the longer arm will carry the flue through the wall in a diagonal direction and will prevent the said flue becoming accidentally detached, as will be readily seen in the accompanying drawings.

I prefer to provide the supply pipe or conduit with any suitable regulating valve or damper, 6, whereby the supply of air admitted to the combustion-chamber may be prop erly controlled.

In some furnaces a single flue D may sufitice. In others a series of lines will more evenly and satisfactorily distribute the air in the furnace. By leading the supply-pipe to the exterior the draft will insure an abundant quan tity of fresh air, thereby making the combustion perfect and preventing the escape of smoke.
