SPECIFICATION forming part of Letters Patent No. 310,920, dated January 20, 1885.
Application filed May 10, 1 884. (No model.)
1"0 ctZZ whom it may concern:
I Be it known that we, HENRY A. SPEAR, of Oharlestown, Suffolk county, Massachusetts, and ALBION P. WIGHT J12, of North Adams,
5 in the county of Berkshire and State of Massw chusetts, have invented certain new and useful Improvements in Smoke Consumers for Locomotives, Stationary Boilers, Stoves, and Furnaces; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters 1 5 of reference marked thereon, which form a part of this specification.
Our invention relates to a special construction of parts, to effect a more perfect combustion, to consume the gases and smoke, and to economize fuel; and it embraces as its leading features the admission of the air above instead of below the fuel in the fire-ehamber, the carrying of the same downward through the ignited coal or fuel, to consume the gases and smoke, and thereby intensify the heat, to consame the smoke and other products of oombus tion, and thence carrying the heated airinto a chamber substantially air-tight, beneath the grate, and thence upward through a passage 0 leading to the boiler or to an outlet-pipe, as
the case may be.
In the drawings our invention is shown in Figure 1 as applied to a stationary boiler, and in Figs. 2 and 3 as applied to a stove. Figs.
t and 5 are sectional detail views of our in vention as applied to a boiler. It will be evident, however, that it may also be applied to a locomotive, or to a furnace or stove for gencrating heat for any purpose desired.
0 Referring to Fig. 1, A represents the fireboX of a stationary boiler; B, its grate, the bars I) of which are preferably made hollow or tubular to allow cold air or water to be run through them to keep them from melting or 5 being damaged by intense heat. These gratebars may be of iron, or of stone or stoneware capable of withstanding a high degree of heat. These hollow grate-bars b communicate with each other by means of two similar hollow bars, If I)".
1 is an opening for the admission of air or water into one of the hollow bars Z), and 2 is an outlet for the same. The water or air will then have a continuous flow from the entrance 1, through one of the hollow bars I) and gratebars I), then through the other bar I), and finally out at the exit 2.
O is a bridge wall or partition, made of stone, brick, or iron, and separating the fireboX or chamber A from a heat-passage, c, behind it, and it extends down some distance be low the bottom of the grate, as shown at 0. Its function is to prevent the draft from passing from the grate and fuel directly to and through the outlet-fines of the boiler, and instead to throw or force it downward through the grate into the chamber E, which is directly under the grate, and the extension 0 of this bridge-wall confines this downward current until it shall have reached the lowermost edge of this extension, and then, as indicated by the arrow, it passes upward through the passage c' to the boiler-fines o, and preferabl by the route indicated by the arrows, to utiize the heated air for the tubes to the best ad vantage.
The bridge-wall c c, which we style a water-leg, is made hollow to admit water or air to pass through it, in order to protect it from damage or melting fromahigh degree of heat. 3 is an opening near the top of the bridge wall O for the admission of the water or air into said bridge-wall, and 4 is a cook or outlet for said water or air. As the air rises, it will be more convenient to use 4 as the inlet for air, when air is used, and 3 for the outlet, and vice versa when water is used.
D is a hinged slatted door having in or near it a slatted slide or air-inlet, serving as an adjustable valve for the admission of air above the fuel to promote combustion. The coal is put in at this door.
F indicates the location or-position of an air-tight aslrpan constituting the bottom of the chamber E.
G indicates the proper place for an exhaustblower, which may be employed, if desired, for the purpose of creating in some cases a stronger draft than would be otherwise induced through the air-inlet openings H of the chamber A, or through its slatted slide-door D, or through both.
If desired, air may be driven into the door D or inlets H by the agency of a pressure blower or a steam-jet.
By our construction the fire pot or box A acts as a retort, in which the coal is coked, the gases extracted, and the cold air entering above-and passing downward unites with the gases and promotes more complete combustion. The same general features are employed and the same principle is involved and by a similar operation, in a stove or furnace or other heater, as illustrated in Fig. 2, in which like letters of reference indicate like parts, the heat in this case passing out by means of a pipe, I, either to heating-pipes or to a chim= ney or otherwise, as circumstances may require. In this case there is no need of the bridge-wall, as the back of the stove, in connection with the opening therein below the grate, where the pipe I is connected, being the only outlet, compels the draft to be in a downward direction through the body of the coal and through the bottom of the grate into the lower chamber, E. The grate-bars may, however, be tubular, for the purpose above stated, and maybe of any desired form or material.
In Fig. 3 the hollow grate -bars connect wlth a pipe, j, running into the smoke-pipe, so that the same air which passes through the hollow grate shali serve to make a draft in this smoke-pipe. \Vhen the smoke-pipe connects with the stove-body at a point near the bottom of the grate, as shown in this figure, it is best to put a piece of iron or metal, as shown at 0, serving the same duty as the extension c in Fig. l namely, to prevent the heat passing directly to the outlet-flue. This deflector-extension may, as already stated, be hollow for the purposes already explained. \Vhen air only is to bediseharged through the extension-pipej, its outlet is preferably within the sm0ke-pipe I. WVhen water only is to pass through this extension-pipe j, this pipe should, as shown in dotted lines in Fig. 3, ex-
tend through or across such pipe, so as not to discharge within it. But both forms may be used in the same furnace or stove, a stop-cock being in such case employed at the bend of j to direct the current either into or away'from the smoke-pipe dependent on whether air or water is used. 7
I11 any stove embodying our improvements there may be a damper in the top to admit or regulate the down current of air for supporting combustion, or a damper in the door above the grate, or both, the dampers being of any ordinary or well-known kind.
