SPECIFICATION forming part of Letters Patent N 0. 661,477. dated November 6, 1900.

Application filed August 3,1899. Serial No. 726,017. (No model.)

To all whom. it may concern.-

Be it known that I, IRA C. MCOLENTHEN, a citizen of the United States, residing at Hebron, in the county of Porter-and State of Indiana, have invented certain new and useful Improvements in Smoke-Consumers, of which the following is a specification.

My invention relates to smoke-consumers for boilers; and its primary object is to providea simple and inexpensive device of the character named which will effectively consume the carbon contained in the smoke in the fire-box, thus materially increasing the combustion and saving fuel, and also avoiding the injurious effects of the soot ordinarily contained in the smoke from locomotive or stationary boilers.

The invention utilizes a combination of dry steam, gaseous vapors, and hot air to efiect the purpose in view, and an apparatus of novel construction which will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a vertical sectional view of a boiler provided with my invention. Fig. 2 is a central vertical section, on an enlarged scale, of that portion of the ipparatus which is located within the fireox. retort of the device, and Figs. 4., 5, and 6 are detail perspective views of parts of the retort.

Referring to Fig. 1 the reference-numeral l designates aboiler of the usual or any preferred construction, having the fire-box 2, tubes 3,and steam-dome 3*, From the dome 3 a steam-pipe 4 extends rearward, connecting by a vertical pipe 5 and a horizontal pipe 6 with the interior of the fire-box 2. The pipe 4 may be support-ed in any suitable manner, as by a bracket 7, projecting above the boiler. The inner end of the pipe 6 is bent downwardly to support the retort of the apparatus within the firebox at an angle of approximately fortyfive degrees.

8 designates an oil-tank supported adjacent to the steam-pipe 6, as by brackets 9, and having a downwardly-inclined spout 10, communicating with an enlarged portion 6, secured to pipe 6 and forming a vaporizingchamber therein. This spout 10 is provided with a cook or valve 11 to control the flow Fig. 3 is a view in perspective of the an asbestos wick 33 below the retort.

of oil to the vaporizing-chamber 61, and the tank is provided with a filling-funnel or oilinlet 12. Below the pipe 6 is suitably sup ported, asby hangers 13, Fig. 1, a burner comprising a frame and an asbestos wick 14 therein adapted to be saturated with kerosene or like inflammable liquid and lighted to generate the initial charge of gas, as will be further explained hereinafter.

The construction of t he retort and its casing will now be described. The upper section of the casing of the retort consists of a concavoconvex plate 15, formed with a central opening surrounded on its outer side by an internally-threaded annular flange 16 and on its inner side with a projecting collar 17. The threaded fiangelti receives the externallythreaded end 19 of the pipe 6, while the inner collar 17 serves as a guide for-the stem of the retort, as hereinafter described. 15. is formed at one side with a lug 20 and at a plurality of points provided with openings 21, into each of which is secured an an gle-pipe 22, serving as an inlet for air. The under edge 23 of the plate is outwardly flared orbeveled to direct the vapors downward and act as a spreader to distribute the vapors over the coal in the fire-box. The lower plate 24 of the casing also consists of a concavo-convex plate arranged reversely to the plate 15, so that the two plates when secured together constitute a hollow chamber 26 to contain the mixer. This plate 24 is formed with a lug 27 and is recessed at the point 28 to-adapt the lug 27 to fit against the .lug of the upper plate 15, to which it is secured by bolts and nuts 29. Plate 24: is smaller in diameter than the upper plate 15, and a passage is formed at the edge thereof to permit the escape of the gases discharged into the casing formed by said plates. The plate 24 is also formed with a central opening or bearing 30, surrounded on its under side by a collar 31, which is preferably grooved annnlarly for the attachment thereto of a burner com prising a hanger 32 for supporting The mixer comprises a hollow sphere," consisting of two selnispherical sections 34 and 35, each formed at its lower side with a solid semicircular lug 36 and at its opposite side with a hollow semicircular projection 37. 'When the The plate two sections '34 and are brought together,

' as shown in Fig. 2, the lugs 36 form-a circuperforate, as shown, while thesection 35 is formed with a series of parallel slots 38, ex-. tending almost entirely across the section for the escape of steam and gas into the chamber 26. These slots may be formed across the plate, as shown in Fig. 2, or lengthwise thereof, as illustrated in Fig. 5.

The operation of the apparatus constructed as above described is as follows: The cook 11 is opened to allow oil to pass into the jacket 6, and the wick 14c is lighted to generate a vapor within the jacket 6 before steam is ad- I mitted. By means of a valve steam is admitted into the pipes 5 and 6. The commingling of steam and gas-with the hot air which enters the pipe 22 materially increases the combustion and consumes the carbon in the smoke, thus effectually accomplishing the purpose in view.

Many of the details of construction herein shown and described may be varied without departing from the spirit of the invention. For example, the means shown for suspending or supporting the wicks may be changed or modified atwill and other minor changes may be resorted'to.
