' Appfication filed July so,
To all whom it may concern:
Be it'known that I, HARRY L. Woon, a citizenof the United States of America, residing at Dowagia'c, in the county of Cass have invented certain new and useful Improvements in Furnace Construction, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to furnaces, and more particularly to furnaces having passages through which air flows, to be heated. The invention consists primarily in the employment of certain plates for connecting inner and outer casing members of a fur nace, which casing members form an air passage, and'in the relation of said plates to the terminal plate for the fuel feed and ash-pit projections from theheater of the furnace.
In the drawing: I
.Figur'e l is a vertical sectional view of the improved furnace, the plane of section being through the fuel feed and ash-pit projections from the heater; j
Figure 2 is ahorizontal section on line 2+2 of Figure 1; I
Figure 3 is a section on line 3-3 of Figure 2, showing a v connection between the feed mouth section ofthe furnace and an adjacent plate. 1
In these views, the reference character A designates a heater having the combustion chamber B and ash-pit C, and having projecting portions D and E, respectively having passages for fuel delivery to the combustion chamber and removal of ashes from I the ash-pit. Said heater is positioned within inner and outer-cylindrical casings F and G, formed preferably of sheet metal and havinggaps at the front of the furnace to accommodate said projecting portions of the heater. The outer casing G extends from top to bottom of the furnace, while .45 the inner casing F terminates slightly above the ash-pit level. The space between the casings F and G forms a passage for the downfiow ofair and an upflow passage is formed between the inner casing and the an arrangement being well The at the front of the outer casing is closed by a plate H having door openings I and J respectively registering with the passages in the por- E, said member II forming a known in the art.

terminal plate for said portions D and E. The lateral margins of the plate H are connected to the vertical edges of the gap in v and oppositely upon the member D, and
angular brackets M carried respectively by theplates It. being bolted to said-lugs as indicated at N. Preferably the brackets M are adapted for alimited vertical adjust. ment upon the plates K by slotting said brackets, as indicated at O, to engage the securing bolts P. By forming the lates K separately from the casings F and i and from the plate H, said plates may be rolled or cast of the necessary thickness to exerc se their spacing and partitioning function, without having either the undesirable flehglblllty or the sheet metal forming the casings, and without complicating production of the plate III. I
is a feature of the described construction that the rear edges of thetwo plates II are stressed away from each otherby the inner casing, when the latter is properly tensioned, and said plates reacting to said stress, pivot upon the bolts N and'bear firmly at their front edges against the plate H. Thus there is established a tight joint between the plates K and the front plate I-I without bolting together or otherwise positively connecting said plates. Thus as the fire-pot and combustion chamber expand and contract, there is nothing to'restrict the plates K and H from-undergoing the slight resulting relative movement, and no breakage of said parts may result from such relative movement. 7
-What I claim as my invention is:
'1'; In a furnace, a heater having projec ting portions, forming passages respectively communication with the chamber and ash-pit of the heater, inner and outer spaced casings about said heater, the outer casing having a gap therein, a terminal plate for said projecting portions havcombustion v ing door openings in registration with said passages, and closing said gap in the outer casingfand a pair of pivotally mounted plates formed separately'from said casings and terminal plate and bearing against the lateral margins of said terminal plate and the vertical edges of the gap in the outer casing and Vertical edges of the gap in the 1111161 casing.
2. In a furnace, a heater having projecting portions, forming passages respectively in communication With: the combustion chamberandash-pit of the heater, inner and outer spaced casings about said heater, having registering gaps to accommodate said projecting portions of the heater, a terminal plate forsaid projecting portions having door openings registering with said passages, said plate closing the gap in the outer casing, and a pair pivotally mounted plates, formed separately from the casings and terminal plate bearing against the lateral margins of said terminal plate and engaging the inner and outer casmgs marginal to said gaps. v
