SPECIFICATION forming partof Letters Patent No. 643,438, dated. February 13, 1960.
Application filed May 10, 1899. Serial No. 716,253. (No model.)
To all whom, it maty cmwrit:
Be it known that we, JOSEPH EDWARD Wore MALD and JosEPH WORMALD, of Spokane, in
the county of Spokane and State of Washington, have invented new and useful Improvem cuts in Heating Stoves or Furnaces, of which the followingis a full, clear, and exact descrip tion.
This invention relates to stoves or furnaces for heating purposes, and has for its object to provide novel details of construction for a device of the indicated character which will adapt it for yery efficient service and afiord a stove or furnace that may be produced at a moderate cost.
The invention consists in the novel construction and combination of parts, as is hereinafter described, and indicated in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding, parts in all the figures.
Figure 1 is a side view of the stove. Fig. 2
is a plan view with the top broken away to,
expose the damper. Fig. 3 is a sectional side view substantially on the line 3 3 in Fig. 2. Fig. 4 is a reduced sectional plan substantially on the line 4: 4 in Fig. 3. Fig. 5 is a perspective view of a draft-controlling ring forming part of the invention. Fig. 6 is a perspective view of a draft-pipe elbow and the damper therein. Fig. 7 is a transverse sectional view of a portion of the lower part of the stovebod y and of a supporting-foot therefor, taken substantially on the line 7 7 in Fig. 2; and
Fig. 8 is a side View of a heat-controllin g damper employed.
While wood is preferred as a fuel for the improved stove or furnace, other combustible matter may be employed as aheating medium.
To enable the construction of the heating device in a convenient and inexpensive manner, we prefer to construct it mainly from sheet metal and assemble the parts as hereinafter described.
The exterior body portion 10 of the heater is preferably oval in form and seats upon the bottom plate 11, a head a on the edge of said bottom plate serving to retain the sheet-metal wall 10 in proper position thereon. The bottom plate 11 may be of cast metal and has a to hold in place a draft-pipe.
central aperture 1) formed in it for passage of air. An inner wall or fire-pot 12 is supported concentrically within the outer wall 10 by two bracket-stands 13, each formed of a flat bar bent at the ends to provide depending legs thereon, that rest upon the bottom plate, said stands being placed transversely of said plate, respectively near each end of the same. The fire-pot 12 and bottom plate ll are held together by bolts 0, that engage lugs a projected from the fire-pot, said bolts appearing in Figs. 3 and 4.. The stove-body and fire-pot are sustained above the floor a proper distance by four legs 14, which pass through apertures made in pairs oppositely through the wall 10 and suitably spaced from each end of the stove-body. The legs 14: have their portions that pass through the stove-body 10 inserted into sockets (1 formed on the lower side of the bottom wall of the fire-pot 12, which adapts sheet-metal wall or body 10, this being a feature of the present invention.
On the upper edges of the oval concentric walls '10 12 a top plate 15 is seated and held in place by bolts 6, that pass down through the top plate and bottom wall of the fire-pot 12 or lugs e thereon.
The dimensions of the fire-pot 12 are such as permit an annular heat space or passage 10 to intervene between the side wall of the fire-pot and the outer side wall '10, said passage having open communication with the air space 10", that is between the bottom plate 11 and bottom wall of the fire-pot.
The top plate 15 is apertured near its center, as atfin Fig. 3, to'perniit the free introduction of fuel into the fire-pot 12, and a preferably dished cover 16 is held in place over the aperture by a hook-like catch g, that enters a slit in the top plate, as shown in Fig. 3.
Rearward of the aperture f a draft-hole is formed in the top plate 15, around which a circular flange 15 is erected from the plate (Not shown.)
The side wall or body 10 is perforated at one or more points for exit of heat, this perfora-, tion being encircled bya thimble 17, and opposite this perforation a circular gate or damper 18 is held to slide toward and from the same for control of heat-current which may escape from the thimble 17 when the aperture it surrounds is open. The thimble 17 is designed to receive one end of a heat conduitpipe, (not shown,) which when in place may extend to an apartment for heating it, and this room may be above or at one side of the room wherein the stove or furnace is located.
- The damper or gate 18 is formed of plate metal that is curved to adapt it to conform to the curvature of the inner surface of the side wall or body 10, and this gate is notched in the edge for sliding engagement with a supporting-bar h, that extends between the thimble 17 and fire-pot 12, as shown in Fig. 2.
Two ears 1' are formed at the center of the gate 18, which receive between them one end of the rockable bar 18, that is pivoted thereto. The bar 18, which in service is the handle for the gate 18, extends outwardly through a slot in the thimble 17 and is pivoted on a projection formed at said slot, the outer portion of the handle-bar having a grip-piece thereon. In use the vibration of the handlebar 18 in a horizontal plane will move the damper-gate 18 toward or from the opening it is opposite in the side wall 10, and thus prevent or graduate the escape of heat from the space 10.
To permit escape of heat directly into the room that has the heater in it, a series of small spaced holes in is formed in the side wall 10, near the top plate 15, and over these holes a band 19, formed of pliable sheet metal, is held to receive slight rotatable movement. The band 19 is perforated and the perforations are at such intervals as will adapt them to register with the similar perforationsin the side wall 10, and it will be evident that a limited rotatable movement of the band-like cover-plate 19 will open the holes m completely or partially, as the temperature may require, the change in position being'effected by manipulation of a thumbpiece it, that projects from the band 19.
At the front end of the oval fire-pot 12 an aperture 0 is formed, over which the upper end of the draft-elbow 20 is secured, a portion of the elbow hanging down into the firepot, as shown in Fig. 3. The elbow 20 may have acast-iron extension-piece 21 hung from its lower portion by a cross-pin p, which is removable, so that if the portion 21 of the draft-pipe is burned out another extension 21 may be readily exchanged therefor.
In the throat of the elbow 20 a damper 20 is suspended and held to rotate by the rod 22, which projects up through the top of the elbow and also through the top plate 15 of the heater. The rod 22 is bent at a right angle near its upper end, so as to project forwardly, said horizontal portion or handle of the damper-rod having seated engagement with arib r on the top plate 15, which serves as a support therefor, and at the ends of said rib upward projections r are formed, which limit the lateral movement of the damper-handle, and will respectively indicate if the damper is open or closed when the handle portion of the damper-rod is in contact with an appropriate projection r.
The operation of the heater is as follows: Fire being made in the fire-pot 12, cold air from the lower part of the room will be drawn into the space 10*, and thence pass through the draft-pipe 21 to supply the fuel in the fire-pot with oxygen for its combustion. As the heat of the fire quickly renders the side wall of the fire-pot 12 quite hot this will raise the temperature of the air that enters the aperture 12 in the bottom plate 11, and the rarefaction of the inducted air will cause it to rise and escape either through the holes m or out of the thimble 17 for transmission of heat to another apartment, as before mentioned.
The manufacture of the body 10 and firepct 12 of sheet metal greatly lightens the stove and cheapens the cost of production, and if wood is used as fuel the heater will be quite durable.
Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination with a plate metal body, a smaller fire-pot held concentrically therein and spaced from the bottom of the body, and a top plate for said body, of legs passing through the plate-metal body and their inserted end portions engaging with sockets formed on the bottom of the fire-pot, thus takingload strain off of the plate-metal body.
2. The combination with an oval platemetal body, and a smaller oval fire-pot held concentrically in the body and spaced from the bottom of the body, thereby providing an air-space around the fire-pot, of an outletthimble on the body near its upper edge and over an aperture in said body, and a controlling-gate of plate metal curved to conform to the curvature of the body, a handle-bar pivoted to the center of the gate and passing through the thimble whereon it is also pivotcd, and a supporting-bar for the gate, extending across the heat-space between the body and fire pot and loosely entering a notch cut in the gate.
