IMPROVEMENT IN SMOKE AND STEAM BURNERS.

Specification forming part of Letters Patent No. 141,277, dated July 29, 1873 application filed April 12, 1873.

To all whom it may concern:

Be it known that we. JOHN W. KINGMAN and ADOLPHUS EURGENS, of Laramie city, in the county of Albany and Territory of Wyoming, have invented a new and useful Improvement in Smoke and Steam Burner, of which the following is a specification:

Figure 1 is a detail vertical longitudinal section of the fire-box of a steam-boilerin which our improvement has been applied. Fig. 2 is a detail vertical cross-section of the same taken-through the line .70 w of Fig. 1.

Our invention has for its object to prevent the waste of heat and fuel consequent upon replenishing the fire with cold fuel; and to utilize the volatile gases, smoke, &c., expelled when coal is added to the fire; and to enable the fire to be used with a less draft than is necessary when the fire-boxes are constructed in the ordinary manner; and to utilize the hydrogen of water as a fuel, by combining superheated steam with volatile carbon. The invention consists in an improved mode of utilizing steam and smoke in furnaces, as hereinafter described.

A represents the fire-box, and B the grate, of an ordinary steam-boiler. O is a box or trough, open at its top, and which is supported upon pivots attached to its ends, and which work in bearings attached to the front and rear walls of said fire-box A. The coal to replenish the fire is first placed in the box 0, where it is exposed to the full heat of the fire. This heat expels the more volatile gases, which, with the smoke, are at once ignited and consumed. At the proper time the box 0 is tilted, and the coke is dumped into the fire, so as to replenish without checking it. D is a steam-pipe leading from the exhaust of the boiler, or from the boiler, and passing through the fire upon the grate B. The pipe D is connected, by a hollow pivot or other convenient means, with a pipe, E, which extends along the bottom of the box 0, and has numerous holes formed in it.

By this means the steam is superheated while passing through the pipe D, and is discharged among the coal in box 0, where it is decomposed, mingles with the smoke and volatile carbon from said coal, and is consumed.

In thisw'ay the steam from the boileris economically burned as fuel. coal in this way before it is placed upon the fire, it will not be necessary to have so strong a draft, and the exhaust steam does not need to be discharged into the smoke-stack to increase the draft, but may be used to heat the water fed into the boiler, by leading it into a spray-chamber in the tank, and thus in some measure securing the advantages of a con- (lensing-engine.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A pivoted fuel-holder, O, in combination with the grate B and furnace A, as and for the purpose described.

2. The steam exhaust pipe D, arranged in relation to the pivoted drying-trough 0, to discharge thereinto, as and for the purpose set forth.

3. The combination of a pivoted box or trough, O, superheating-pipe D, and distributing-pipe E, with the fire-box of a steamboiler or a smelting-furnace, substantially as described. JOHN W. KINGMAN.
