STEAM-BOILER.
SPECIFIGATIGN forming part of Letters Patent N 0. 741,779, dated October 20, 1903.
I Application filed March 9. 1903. Serial No. 146,963. (No model.)
1'0 aZZ whom it may concern.-
Be it known that I, JAMES W. EAST, a citizen of the United States, residing at Tate Springs, in the county of Grainger and State of Tennessee, have invented certain new and useful Improvements in Steam-Boiler Attachments; and I do 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 improvements in steam-boilers and the combination therewith of means for heating air in furnaces, forcing said heated air into the steam-space of the boiler, and superheatin g said heated airin the boiler before the discharge into the steamspace thereof.
With these and other objects in View the invention consists in the combination and arrangement of the parts, as will be hereinafter more fully described and claimed, reference being had to the accompanying drawing, in which is shown a diagrammatic sectional view illustrating the arrangement and application of the system.
In the drawing, 1 denotes a boiler, which may be of any well-known type. 2 denotes the steam-dome. 3 denotes the fire-box, 4 the ash-pit, and 5 denotes the grate. Arranged at the rear of the fire-box upon the grate-support is an air-heating drum or cylinder 6, extending transversely across the fire-box and serving as a bridge-wall. Above the top row of boiler-fines is arranged a coil of air-pipes 7, the upper end of which opens into the steamdome. The opposite or lower end of the coil is connected to an air-pipe 8, which is connected at its opposite end to an air-pump 9.
1O denotes an air-pipe, one end of which connects with the air-heating drum, and its opposite end communicates with the air-pump 9. Check-valves 12 and 13 are arranged in 'the pipes 8 and adjacent to their connection with the pump 9.
14: and 15 denote globe-valves, also arranged in the pipes 8 and 10, by which the airin said pipes is controlled.
'16 denotes the cylinder.
17 denotes the piston-rod, 18 the crankshaft, 19 the flywheel, and 20 the pulleywheel, of an engine of any suitable type, and 9 denotes the piston-rod of the pump 9.
21 denotes the driven wheel of the pump, connected by a belt to the pulley on the engine-shaft 19, and 22 denotes a pitman conmeeting said driven wheel with the pistonrod of the pump.
23 denotes the engine feed-pipe, connecting the steam-dome with the engine-cylinder and through which steam and air are conveyed from the boiler to the engine. 7
In practice cold air is admitted to the heat ing-drum 6, where it is heated. -From the heating-drum the hot air is pumped through the pipe 10 intolthe pipe 8 and thence to the coil of pipes 7, where it is superheated, and from the coil it is discharged into the steamdome, where it mixes with the steam and is fed to the engine-cylinder.
While I have described the cold air as first entering the heating-drum, it is obvious that I may first introduce the cold air to the coil of pipes in the boiler and from these pump it through the heating-drum and then discharge the same into the steam-dome.
By locating the heating-drum at the rear of the fire-box the same is made to take the place of the ordinary bridge-wall of brick, thereby serving a double function.
From the foregoing description, taken in connection with the accompanying drawing,
the construction and operation of the invention will be readily understood without re-,
quiring a more extended explanation.
Various changes in the form, proportion, and the minor details of'construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. In combination with asteam-boi1er, asuperheating-coil therein discharging into the steam-space thereof, an air-heating drum in the furnace, and means to draw air from the said drum and force the same through the superheating-coil and into the steam-space of the boiler, substantially as described.
2. In a steam-boiler, a superheating-coil therein discharging into the steam Q space thereof, an air-heating drum disposed trans- In testimony whereof I have hereunto set vei'sely in the boiler-furnace, in rear of the my hand in presence of two subscribing Wit- IO fire-box and forming a bridge in the furnace, nesses. and means to draw heated air from the said 5 drum and force the same through the superheating-ooil in the boiler and discharge the Witnesses: same into the steam-space of the boiler, sub- M. E. DYKES, stantiaily as described. L. F. JARNAGIN.
