DEVICE FOR PROMOTING COMBUSTION.

SPECIFICATION forming -part of Letters Patent No.. 300,080, dated June i0, 1884. Application filed March 12, 1884. (No model.)

To all whom it may concern:

Beit known that I, WALTER M. Jamison, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Devices for Promoting Combustion, and I do hereby 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.

My invention relates to an improvement in devices for the promotion of the combustion of fuel, the object of my invention being to provide a device of this character which shall be adapted to conduct a thin sheet or jet of steam enveloped in heated fresh air into and upon the ignited surface of abed of combustible material, for the purpose of decomposing said steam by being brought in contact with `carbon in an incandescent state and burning the gases resulting from such decomposition,

and thereby promoting combustion by preventing the escape of the free carbon,the parts to be so constructed and arranged that the products of combustion will be prevented from mixing with the steam or air before they issue from a common outlet;v and with these ends in view my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation of my improvement. Fig. 2 is a vertical section thereof. Fig". 3 is a plan View of the upper and lower ends of the tube or air-supply pipe.

A represents the tube or air-inlet of my irnproved device, being provided at its upper and lower ends with the cross-arms or supports B, said tube being held in position in the walls of the fire-box by the nut G. The central portion of the bracket B is enlarged in cross-section, as shown in Fig. 3, and is provided with a hole or perforation, a, through which passes the steam-pipe D, the lower end of which extends a short distance beyond the lower end of the tube, and is provided with a male screw-thread, as shown at b, the said steam-pipe D being held in proper position by 5o a lock-nut, c, fitting on the steam-pipe and -steam or heated air before theyT escape into or impinging against the bracket or support B. The upper fend of the tube A is providcdwith a male screw-thread, d, on which fits the head or shell E, preferably of the form shown, the curved end of which is provided with au elongated slot, F, through which passes the heated air from the tube A.

To the screw-threaded end of the steam-pipe VD and within the shell E is secured the nozzle G, the lower end of which extends within a 6o short distance of the lower end of the shell E, said nozzle being provided at its lower end with the slot e, registering and running in the same direction with the slot F, said slot e being preferably formed a little slanting. 65

My improved device is placed over the burning fuel, the tube A being connected with the fire-box and the pipe D with the boiler,through which pipe the steam passes and issues through the slot c, which, being made slanting, throws 7o the widened jet of steam at an angle on the fire. The steam, passing out of the slot in the shell E, draws the heated air up through the tube A and envelops and passes out with the jet of steam. By this construction and arrangement of parts the material products of combustion such as carbonio, sulphurous, and phosphorous acids and nitrogen-are prevented from becoming mixed with either the over the fire through the common outlet, the shell E being tightly closed around the tube A. Instead of using the tube A, the shell E might be tightlysecured to the fire-pot, and a cemented or packed joint may be made against the 8 5 inner wall of said pot, to prevent the admixture of the products of combustion with the air or steam before'they issue from the shell.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, with an air-heating tube provided at one end with a shell having an elongated air-discharge opening, of a steampipe provided with a discharge-nozzle located within said shell, said nozzle having an elongated opening formed therein, the opening in the steam-nozzle being located in close proximity to the air-discharge opening, the parts being constructed and arranged to inject into IOO the fire-box a thin jet of steam enveloped by a thin stratum of heated air and prevent the ingress to the shell of the products of Combustion, substantially as set forth.

2. The combination7 with an air-heating tube provided at one end with a shell forming au enlarged air-Chamber, said shell having an elongated air-discharge opening, of a steampipe provided With a nozzle located Within the shell, said nozzle being provided with an elongated opening located in elose proximity to the similar shaped opening in the shell7 substantially as set forth.

3. The combination7 Withthe tube provided
