I JOHN HENRY STONE, OF TORONTO, CANADA, ASSIGNOR TO MARIE LOUISE STONE, OF TORONTO, CANADA.
COMBINED HEATING AND COOKING OIL-STOVE.
SPECIFICATION formingpart of Letters Patent No. 759,404}, dated May 10. 1904..
I Application filed March 81, 1903.
To all whom it may concern:
the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in a Combined Heating and Cooking Oil-Stove, of which the following is a specification.
My invention relates to improvements in combined heating and cooking oil-stoves; and the object of the invention is to produce a stove of this class which will generate a maximum amountof heat for a minimum amount of oil, and, further, to simplify the construetion of the stove so as to adapt it for both heating and cooking; and it consists, essentially, of a bowl having a bottomless tube extending through the center of the same and surrounded on the exterior within the bowl by copper and zinc members designed to be immersed in the oil, burners supported in suitable necks and having substantially split tubular copper and Zinc members designed to be spring-held within the burners, reverselyset truncated-cone-shaped flues designed to be supported on the burners and having connected at the top the truncated-cone-shaped extensions and having extending outwardly therefrom flanges, a supporting-plate provided with openings and a rim, the edge of such opening being designed to be supported on the flanges of the lower portions of the fines, a cylindrical casing supported on the rim of the plate, a top plate provided with, cross-bars, a supplemental cylinder fitting the rim of the top plate and provided with a suitable top, and a plurality of sheet-metal rings extending from the bottom of the supplemental casing to near the top thereof and located, preferably, concentrically one within the other, the parts being otherwise arranged and constructed in detail as hereinafter more. particularly explained.
Figure 1 is a perspective exterior View of my improved stove. Fig. 2 is avertical section through the stove. Fig. 3 is a detail of of the central tube. bottom plate of the stove.
Serial No. 150,357. (No model.)
of the top plate. Fig. 6 is a detail of one of the radiating rings. Fig. 7 is a detail of the burner and copper and zinc tubular members spring-held in the bottom of the same. Fig. 8 is a side elevation of the tubular member.
In the drawings like letters of reference indicate corresponding parts in each figure.
A is the base-bowl of the stove, which is provided with suitable legs a. a
A is the tube, which extends through the center of the bowl and is provided with the copper and zinc members a and a a detail of which is shown in Fig. 3.
B is the burner,which is suitably screwed into the neck 6 at the top of the bowl. I have shown four burners; but there may be a lesser or greater number, as desired.
C is a tube formed of copper and zinc members 0 and c, the Zinc member being innermost and as the tube is a split tube is bent outwardly at c 0 at each side of the split over the outer copper member.
0 is a rim or bead formed near the upper end of the split tube C. By pressing the tube together at the split it will be readily seen that it may be contracted, in diameter, so as to fit and rest upon the shoulder I) at the bottom of the burner B, and thereby maintain the tube in position.
The burner B is shown with a flat wick D; but this is not necessarily so, and such flat wick passes down through the tube C and is necessarily curved as it passes through such tube to conform more or less to the contour of the tube, depending, of course, upon the width of the wick.
E represents reverse cone-frustum-shaped flues, which fit on the top of the burner, as indicated, and E represents the extensions of the tube, which are cone-frustum shaped and are bent around the upper flange of the lower portion of the flue, as indicated, in order to form a supporting-flange.
F is a plate provided with a series of openings f and a rim f, located a little distance from the edge. The edges of the openings f are designed to be supportedby the flanges e, and thereby support the plate in position.
The plate F is provided with a central opening f and perforations f, as indicated, so as to permit of the upward passage of the cold air.
G is a cylinder which is fitted over the rim f and extends upwardly, as indicated.
H is a supplemental plate, which is provided with a depending flange 7L and a raised flange 7L, having extending therebetween the cross bar If. The plate H is supported by the cylinder Gr and the flange /t fits within the cylinder, as indicated.
I is a supplemental cylinder, which extends upwardly from the plate H, the bottom of the cylinder fitting snugly the flange it on the outside.
J is the top, which may be of any ornamental d esign and perforated. The top J is connected by a central rod 7' to a bar or web formed or secured within the cylinder I, secured to the bottom.
K represents a series of cylinders fitting one within the other and resting on the web j and provided with turned out projections 70, which serve to maintain the cylinders equidistant apart or concentric to each other.
Having now described the principal parts involved in my invention, I shall briefly describe its utility. The central tube A, extending through the oil-bowl, will necessarily draw the cold air from the bottom of the stove once the burners are lighted and heats it as it ascends into the body of the stove. The members surrounding the tube, as well as the detachable tubes connected to the burner, serve to coact with the chemicals contained in the oil and used in the deodorizing of the same to materially increase the heat from the flame of the burners. Whether it is by the gas generated thereby passing up to the wicks and burners or from a battery formed I cannot say, but the result I have proved. Such heat passing upwardly through the flues E and E and cylinder H into the radiating rings or cylinders K serves to produce an extremely high degree of heat, which as far as I am aware has never been obtained in any other oil-stove.
If it is not desired to use the upper cylinder I, of course it maybe removed and the bars I2 may be used for cooking upon. I find in practice also that not only is the heat produced by the action of the tubes comprising the members as I have hereinbefore described, but that all smell from the oil is completely eliminated. The arrangement of the radiating cylinders or rings is also very important, and I produce thereby a maximum radiation of heat for a minimum size of flame in the burners.
, When I remove the upper cylinder I for cooking purposes, I preferably substitute therefor a cylinder of larger diameter, which is designed to extend upwardly around the cooking vessel, and by this means the heat instead of radiating is conserved and directed to the body of the vessel, thereby materially increasing the heat an d the rapidity with which cooking may be done.
hat I claim as my invention is 1. In an oil-stove, the combination with the bowl and central air-tube extending upwardly through the same, and the burners suitably held in the top of the bowl and having the wicks extending thcreinto, of the flues extending upwardly from the burners, and the cylinders supported on the flues and forming an airchamber in communication with the flues and the central tube, as and for the purpose specifled.
