FURNACE-DOOR.
SPECIFICATION forming part of Letters Patent No. 592,976, dated November 2, 1897.
Application filed June 14, 1897.
To all whom it may concern:
Be it known that I, HENRY C. TALBOT, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Furnace-Doors; and I do declare that the following is afull, 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.
My invention relates to furnace-doors; and my improvement consists in the new and novel construction, substantially as shown and described, and more particularly pointed out in the claims.
The object of this invention is to provide furnaces with a door constructed with means to govern the amount of air and draft which passes to the grates and fire, thus providing suitable means for promoting the best results in the combustion and efficiency of the furnace. In connection therewith a fire-lining or inner air-jacket is used to prevent the burning out of the door from the intense heat of the fire.
Figure 1 is a perspective view of the front part ofa furnace with my improved door thereon. Fig. 2 is a central longitudinal section taken on line 2 2, Fig. 1.
In the accompanying drawings, A represents the front of a furnace, having lugs 2, upon which the door B is hinged, and a lug 3 at the opposite side forms a catch to lock the door when closed. A hollow gate 0 is pivoted on lugs 4 at each side of an opening 5 in the face of the door, and this gate is open at its bottom and has a longitudinal slot 6 at its upper end. The upper end is circular in cross-section and is pivoted in such close relation to the rib 7 that when the gate is swung in or out the opening at slot 6 is narrowed or widened, thus governing the amount of incoming air at this point. The air passes through this slot 6 and down and out of the opening at the bottom of the gate, passing from here to the fire. Air is also admitted through the opening 5 of the door at the bottom edge of the gate, and the amount of air at this point is also governed by the swinging in or out of the gate. A rack S, pivoted to the bottom of the door, works in looking relagerial No. 640,694- (No model.)
tion with a lug 9 on the door and provides the means for adjusting and locking the gate in any preferred position. The openings 5 and 6 can be entirely closed or fully opened, according to the needs of the fire.
The rear or inner side of the gate is provided with numerous perforations 10, through which a sufficient amount of air is admitted to the inside of the door to keep the same cool and prevent it from burning out. In addition to this the door proper has an inner shield or lining 11, which forms a hood into which the air from perforations 1O ascends, the air escaping through perforations 12 in the shield. The air-chamber formed by shield 11, in connection with the shield itself, forms a perfect means for preventing the burning out of the door, While equally distributing the supply of air. The most of the air is intended and does come to the bottom of the gate and is distributed to the fire,where it is most needed.
In connection with the door I show a series of steam pipes and jets 13, located above the same and at the front of the furnace, but the door can be used With or without these jets and still give efficient results in perfect combustion.
' What I claim as new, and desire to secure by Letters Patent, is-
1. A furnace-door provided with a hollow gate pivoted thereon, openings in said gate controlling the amount of air passing into the furnace, means to swing and lock said gate, and a shield on the inner side of said door to protect the same from the heat, substantially as described.
2. A furnace-door and an opening in said door, a hollow gate open at each end and pivoted in said opening, means to swing and lock said gate to control the amount of air ad1nitted by said gate, and an inner heat-protecting shield for said door, substantially as described.
3. A furnace-door, an opening in said door, a hollow gate open at each end and pivoted in said opening, perforations in the inner side of said gate, means to swing and lock said gate to control the amount of air admitted through the openings in said gate and door, and a perforated shield on the inner side of said door forming a cooling-chamber above TOO and behind said gate to prevent the burning means to hold said gate in different positions out of said door, substantially as described. of adjustment, substantially as described. 10 4.
