Cole and Hugh It. @ole, (Chicago, lfll. Application February 141, 1931. Serial No. 515,799 4 Claims. (oi. 126-93) This invention relates to improvements in stoves and more particularly to oil burning stoves.
It is an object of this invention to provide an eflicient and yet inexpensive stove of this character so constructed as to burn any kind of liquid fuel and produce a high degree of combustion.
The accompanying drawings illustrate a preferred form of this invention with the understanding that minor detail changes may be made without departing from the scope thereof.
Figure 1 is a vertical central sectional view of an embodiment of this invention;
Figure 2 is a top plan view of Figure 1; and
Figure 3 is a view in section taken on the line 33 of Figure 1, with parts broken away.
In carrying out this invention as here shown a circular sheet metal casing 1 is provided whichis closed at the bottom and provided with a removable cast top 2 provided with a flue opening 3 adapted to be connected by stove piping to a chimney or the outside atmosphere. The top 2 is also provided with a central opening and means for attaching a vertical blast pipe 4 to communicate with said central opening. The upper surface of the top surrounding the central opening is formed to mount a movable closure 5 adapted to regulate the size of the passageway communicating with the pipe 4.
A short distance above the closed bottom of the casing 1 a removable fuel receiving and burning bowl 6 is supported upon an annular bracket '7 secured to the inner side wall of the casing 1. The periphery of the bowl 6 is preferably provided with a horizontal flange 8 adapted to rest in a similarly shaped recess upon the annular bracket 7. The bowl 6 is preferably shallow, that is if the inner diameter is ten inches its depth is approximately three inches. The center of the bottom of the bowl 6 is provided with curved conical projection 9 with a diameter at the base of the cone about equal to the depth of the bowl and extending upward about one third of the depth of the bowl. As clearly shown in the drawings the apex of the conical projection 9 is somewhat flattened for described.
The blast pipe 4 carried upon the top 2 is concentric with the conical projection 9. It is de- 5 sirable to construct the blast pipe of a diameter about equal to the radius of the base of the conical projection 9 and terminate the discharge of the blast pipe or its continuation as presently described approximately one fifth of its diameter above the surface of the cone 9, thus causing the sides of the bowl 6.
same general plane.
a purpose presently discharge end of the blast pipe to extend into the bowl 6 to be below the periphery of the bowl, as is clearly shown in the drawings. To maintain this relation it is preferable to provide a tubular chair 10 providing a'continuation of the blast pipe '4 and having spaced apart legs 11 adapted to rest upon the sides of the cone 9, the.
inner diameter of which chair equals that of the blast pipe 4 and the upper walls of which are re cessed to receive the end of the blast pipe, as shown.
A liquid fuel tank 12 is supported in any desired manner upon the exterior of the stove and is provided with an oil pipe 13 to discharge the liquid fuel from the apex of the cone 9, as through the portion 13b of the oil pipe 13 which passes through the conical projection 9 and terminates at the apex thereof, the flow of which fuel is regulated in any manner desired, such as by a float valve mechanism indicated at 13a, to produce a constant rate of discharge at the apex of the cone 9 from which the fuel flows or spreads equally passing over the curvedsurface to the The somewhat flattened curved apex of the projection 9 promotes a gradual spread of the oil which permits the air from the blast pipe 4 to mingle intimately therewith. A cook or valve is interposed in the fuel line, if not combined. with the float valve, to initiate and stop the flow of the liquid fuel.
The natural draft from the chimney or atmosphere sets up through the flue opening 3 an air exhausting effect upon the interior of the casing 1 above the bowl 6 and therefore sets up a. down draft through the blast pipe 4. This draft is employed to furnish primary air for combustion of the liquid fuel when the stove is operating. It is preferable to provide a plurality of horizontal air passages 14 through the wall of the bowl opening just under the flange 8, the axes of which are tangential to an annular region vertically above the base of the cone 9 and extend in the These air passages are desirably above the discharge end of the blast pipe as shown. The space between the bottom closure of the casing 1 and the underside of'the bowl 6 is provided with an opening 15 leading to the atmosphere, preferably provided with a movable closure 16, whereby the natural draft through the flue opening 3 not only sets up a down draft through the blast pipe 4 but also draws air from the atmosphere through the bottom opening 15' into the space below the bowl 6 and from thence through tangential passageways 14 adjacent the upper edge of the bowl with a swirling movement I 16 the proportion of the primary and secondary curved apex of said cone,
air is regulated in accordance with the character of the fuel employed.
In operating this stove, the fuel line valve is opened allowing the fuel to spread over the cone 9 and a match, piece of burning paper or other means of ignition is applied through the door 1'7 of the top 2. The fuel will burn with a smoky flame as insufllcient air for complete combustion is supplied through the blast pipe 4. The draft down pipe 4 impinging upon the cone 9 will cause the flame to spread to the outer edge of the bowl 6 where it comes in contact with the secondary air issuing with a swirling motion from the passages 14 causing a mixture of the secondary air with the gases from the incomplete combustion of the fuel, unite therewith and form complete combustion so that the flame becomes yellow or luminous and fills the lower portion of the casing 1 above the bowl 6.
The heat from the flame, as the stove operates, not only heats the pipe 4 so that the air issuing from below the chair l0 impinges upon the fllm of the liquid fuel upon the top of the cone 9 as a hot blast of approximately nine hundred degrees Fahn, but also the heat of the flame is transmitted through the wall of the bowl 6 to the space therebelow, whereby the secondary air entering through opening 15 is pre-heated before it mixes with thegases of incomplete combustion. The heat at the cone 9 is so great that any carbon that may be collected thereon is immediately oxidized by the hot blast from the pipe 4.
A'stove of this construction when started immediately begins normal operation and radiates heat. If desired a spaced apart shell 18 may be supported about the exterior of the casing 1, as shown, to set up a more violent circulation of air adjacent the stove.
