W drzogya "UNITED STATES PATENT oFrics HENRY S. MARVIN, OF SAN DIEGO, CALIFORNIA.
RANGE.
Application filed April 9,
To all w 710m it mag concern Be it known that I, HENRY S. MARVIN, acitizen of the United States, residing at San Diego, in the county of San Diego and State of' Ualifornia, have invented a new and useful Range, of which the following is a specification.
various kinds of fuel may be used such coal, wood and gas, but more particularly relates to a range in which gas is used as a fuel, and the principal object of my invention is to produce a range of the class described, of simple form and construction, and which is economical in the use of fuel.
Other objects and advantages will be made evident hereinafter. I
Referring to the drawings, which are for illustrative purposes only,
Figure 1 is a longitudinal sectional view of a range embodying my invention.
Fig. 2 is a cross sectional view on lin 2-2 of Fig. 1, and
Fig. 3 is a cross sectional view on line 3-3 of Fig. 1.
The range shown consists of a rectangular casing having a top 11, end walls 12 and 13, a rear wall 14, front wall 15 and a bottom 16 supported on suitable legs 17. 18 and 19 designate ovens having a heat chamber 20 formed therebetween, the upper end of the chamber. being closed by means of a saddle 21 which rests upon the ovens 18 and 19 and which, together with the tops 22 of the ovens, forms an upper heat passage 23 between the same and the top 11 of the stove. The heat passage at the front end connects with a fire box 24 formed between a vertical wall 25 and the forward end 26 of the oven 18, the bottom wall 27 of the oven 18 being extended forwardly to the lowerend of the vertical wall 25, the vertical wall 25and the end wall 13 of the range forming therebetween a flue 30 which connects through a passage 31 in the top of the stove to any suitable stack or chimney, not shown.
The horizontal wall 27 of the oven 18, that is the bottom of the oven, and the bottom 32 of the oven 19 are spaced apart from a horizontal wall 33 which extends entirely across the range thereby forming therebetween a lower heat passage 34, the upper heat passage 23 and the lower heat passage 34 being connected at one end of the oven 7 Specification of Letterslatenta Patented J 1918. Serial no. 227,805.
by a passage 35 formed between the end wall 12 of the range and the wall 36 of the oven 19.
38 designates a grate upon which fire bricks 39 are placed, the upper corner 40 of the oven 19 being also protected with fire brick 41. My invention relates to ranges in which Extending through, the walls 13 and 25 and the flue 30 are a series of thimbles or sleeves 42 which consist of short pieces of pipe, the ends of which are rolled or beaded over the supporting walls.
7 45 designates a gas supply pipe having suitable gas valves 46 which deliver gas through an air mixer 47 into a pipe 48, the pipe 48 being connected to a fitting 49 with the burner 50. The burner consists of a pipe which extends through the thimble 42, the pipe being of smaller diameter than the in-- ternal diameter of the thimble thereby forming a circular passage 51 about the burner 50, it being understood that each burner is provided with a separate gas valve connection such as heretofore described.
The oven operates in the following manner:
The valves 46 are turned on and the gas passing through the connections to the burner is first mixed with air by the air mixer 47, which may be of any well known and common form. The mixture delivered through the burner may be lighted through a removable plate 55 in the top of the stove. The products of combustion pass from the combustion chamber or fire box 24 through the upper heat passage 23, the passage 35, the lower passage 34, thence out the fine 30. Such heated gases passing through the fine 30 heat the respective thimbles 42 therein and warm the air passing therethrough to the burner.
The gas bein burned at the tip of the burner draws air through the passage 51 formed in the respective thimbles thereby delivering a secondary supply of air directly around the burner tip, this air being heated due to the fact that the thimbles through which such air passes are located in the flue of the range. The utilization of this secondary supply of air permits the volume of gas to be cut down as the introduction of such heated air around the tip ofthe burner causes a more perfect combustion than when air is simply mixed with the fuel at the primary or air mixing chamber.
Vfhile l have above described the range as operating with gas, the same may be readily converted to a wood or coal burning range by removing the fire bricks 39 in which case the grate supports the fuel having thereunder an ash receptacle 60 provided with a suitable door 61.
62 designates suitable doors for the ovens and 63 designates chambers by which air may be introduced to the lower heat passage 3d thereby regulating the temperature of the same.
lVhat I claim is l. A range comprising a casing, a combustion chamber in the casing, an oven in the casing, a flue formed in the casing between the combustion chamber and one end of the casing, said oven and easing forming heat passages connecting the combustion chamber and the flue, a thimble extending through the end of the casing and flue to the combustion chamber, and a burner of smaller diameter than the inside of said thimble extending through the thimble forming an annular air passage about the burner from the exterior of the casing to the combustion chamber and delivering a circular current of warm air about the flame.
2. A range comprising a casing, a combustion chamber in thecasing, transverse walls extending across said casing forming a pair of ovens therein, a flue formed at one end of the range between the combustion chamber and an end wall of the casing, a horizontal partition in the bottom of said range, said ovens being spaced apart from said horizontal partition to form a heat passage, a series of thimbles extending through the end of the casing and flue to the. combustion chamber, a burner extending through each thimble, each forming an annular air passage from the exterior of the casing to the combustion chamber, and delivering a circular current of warm air about the flame, a main gas supply pipe, a gas and air mixer connected to the main supply pipe for each burner and means for conducting the mixture to each burner.
In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 3rd day of April, 1918. V
