GRATE POR BOILR PURNACESE I 4//////////////////////lll/ UNITED STATES l ATENT rricn.
LLGR/ire: FOR BolLl-:R-FURNACES.
SPECIFICATION forming part of Letters Patent No. 265,039, dated september 2e, 1882.
pplication filed August 2, 1882. (No model.)
To all whom 'it may concern:
Be it known that we,MUR1LLO DOWNER and JOSEPH MoHa,[of Chic igo, in the county of Cook and State of Illinois, have invented certain new andusefullmprovementsin Grates for Boiler-Furnaces; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of this specification.
The object of our invention is to produce a grate for boiler and other furnaces that will admit air to the fuel not only through the intersticcs between the grate-bars upon which such fuel rests, but also to the sides and top of such fuel, so as to insure a more perfect combustion ofthe gases, and to prevent the formation of smoke; and it consists in surrounding the main grate with a vertical grate that is a sufficient distance from the side and bridge walls, and with an inclined grate that covers the spaces between the walls and the vertical grates also,in intersecting such main grate by two parallel vertical grates that are connected on top by a longitudinal grate, all.
in a manner that the fuel lies in one or several shallow pockets or baskets of grates that insure free entrance of atmospheric air to such fuel from the bottom to all sides.
In the accompanying drawings, Figure l represents a vertical cross-section of a boilerfurnace havin g ourimproved grate, and Fig. 2 a plan view of such grate.
Corresponding letters in the several figures* of the drawings designate like parts.
A and A denote the side walls of a boiler` furnace; B the bridge-wall, and C the boilerfront.
D is the fiat grate, composed of a series of longitudinal bars that are supported at their ends upon cross-bars a in the usual manner. This grate D is of less dimensions than the distance between the side walls and between or nearly vertical, grate, d, to the top of the edges ofthe main grate D, alndon top of this vertical grate d to form au inclined grate, e, that covers the spaces between the furnacewalls and such vertical grates. The vertical grates d we prefer to cast with bars having vertical interstices, and the top grates, e, with bars having longitudinal interstices for holding the fuel from dropping into the `ash-pit, and for admitting a large amount of air to the burning fuel, which air, in passing between or throu gh the heated grates, will be heated itself before admixin g with the gases, and thereby such air will be in a favorable condition for being worn and burned out, since no incandescent fuelV will be brought in contact with such walls.
A Large grate-surfaces we also intersect by a longitudinal grate-box', F,that consists of two parallel rows of nearly vertical bars, d', connected on top bya series of longitudinal bars, e', `and lin some furnaceswe even intend to have a similar vertical grate between the boiler-front and main grate.
The above device, as will be noticed, is very simple in its construction, and does not add much to the expense of a furnace-grate, while its arrangement is such that an ample amount of atmospheric airis admitted to thefuel from the ash-pit" without any extra openings or vents in the boiler-front, side, or bridge walls for admitting air above the grate, or any devicesl for au articial draft by means ofI a steamblast or other agents.
' What we claim is- The main grate D in a boiler-furnace, in combination with the sectional perforated angular plates E, consisting of .upright grates d and inclined top grates, e, the whole being constructed and arranged substantially as and for the purpose set forth.
2. In a boilerfurnace, and in combination ICO therewith, the main grateD,the upright grates E, surrounding said grate D, and the grate-box F, consisting of the Vertical bars d and longitudinal bars e', and intersecting,` said grates E,
