Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed May 19, 1911. Serial No. 628,228.-

To all whom it may concern Be it known that I, GEORGE V. BLAKESLEY, a citizen of the United States, residing at county of Jackson and State of Missouri, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to gas burners and more especially to burners for ranges adapted for burning either gas or coal, and my object is to produce a gas burner for use above the oven by which a baking heat can be imparted to the oven.

Another object is to produce a burner for use above the oven, which will operate efiiciently with either artificial or natural gas, and without regard to whether the burners in the fire pot are in operation or not.

Another object is to produce an eflicient gas burner to heat the oven alone or to cooperate with other burners in heating the oven.

l/Vith these general objects in view and others as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which:

Figure 1, is a central vertical section of the body of a combined solid fuel and gas range, embodying my invention. Fig. 2, is a fragmentary top plan view of the same with part of the top of the range body omitted.

In the said drawings, 1 indicates the body, 2 the fire pot, 3 the ash pit and 4 the oven of a range of the type shown or any well known type, and said range is also provided with the customary chamber 5 between the oven and the top of the body, the customary down-draft passage 6 between the oven and the end wall of the body, and the customary passage 7 between the oven and the bottom of the body.

8 is a gas-supply pipe supported by one or more brackets 9 projecting from the front wall of the body 1, and communicating with said supply pipe is a valve-controlled pipe 10 projecting into the fire pot and closed when only solid fuel is burned, by a hinged cap 11, for exclusion of coal and ashes. When burning gas the cap is raised, and a detachable burner 12 is fitted on the inner end of pipe 10, the arrangement being such that the heat from said burner is directed toward the adjacent opening 13 in the top of the body, the products of combustion following the course indicated by the arrows, Fig. 1. In practice there will of course, be a pipe 10, cap 11, and burner 12 adjacent to each of the openings 13, above the fire pot. 14 is a sheet metal collar depending through one of the openings 13, above the oven, and said collar is provided at its upper end with an outwardly-projecting flange 15 to rest on the lip 16 of the top of the body, and at its lower end with an inwardly-projecting flange 17 18 indicates a circular burner snugly embraced by and resting on the flange 17 of the collar and provided with burner orifices l9 and an inwardly-projecting flange 20 inward of the burner orifices, and 21 is a circular cap resting on flange 20 and provided with a plurality of openings 22, and with an ordinary cavity 23 for the reception of a. lid lifter.

The burner 18 is provided with a gas-supply tube 24 communicating with mixer 25 through which gas from pipe 8 passes, the flow of gas to burner 18 being controlled by valve 26.

In operation the gas passes upward through orifices 19 where it is ignited and the flame extends upwardaround the cap and inwardly over. the outer portion of the same and is sucked down through the openings 22, by the draft through chamber 5 of the range, it being noted that the proximity of the burner to the top of the body does not impair the efficiency of the former in burning natural gas because the products of combustion are instantly sucked down as explained, and cannot smother the flame. In practice the burner operates so effectively that cap 21 is quickly raised to a redheat and the products of combustion pass over and around the oven as hereinbefore explained in connection with the operation of burner 12, and raise the oven to baking temperature. I

In the operation of the burner above the oven, the oxygen to support combustion is supplied through the overlying opening 13, to the interior of the collar, passing through the customary skeleton plate or spider, bridging such opening 13, for the support'of a cooking utensil, not shown, said spider not being illustrated as it is of common and well known construction in gas stoves and forms no part of my improvements. By

protecting the gas as it emerges from the orifices 19, by means of the collar 14-, from the draft and products of combustion in chamber 5, from the fire pot or the burner or burners therein respectively, it is impossible for the flame of burner 18 to become smothered or extinguished.

From the above description it will be apparent that I have produced a gas burner embodying the advantages enumerated in the statement of the objects of the invention, and which is susceptible of minor changes without departing from the scope of the appended claims.

I claim:

1. In a range having a draft passage and a lid hole thereabove, a collar within said passage and communicating with said lid hole, an annular burner inclosed by the said collar and provided with orifices, a cap 13 r the burner, provided with openings down through which the flame from the burner extends into said passage, and a valve-controlled gas supply pipe connected to the burner.

2. in a range having a draft passage and a lid hole above said passage, a collar pendent from said lid hole into said passage, an annular burner inclosed by said collar, and

memes provided with a series of orifices, a cap for the burner to cause the flame therefrom to rise, and provided with openings down through which the flame extends into said draft passage, and a valvecontrolled gas supply pipe connected to the burner.

3. The combination in a range of a collar, a burner inclosed thereby, provided with a central opening and a series of orifices around said opening, and a cap covering said opening, said cap being provided with openings around its margin.

4. The combination in a range oi a collar provided at its upper margin with an outwardly-projecting flange and at its lower margin with an inWardly-projecting flange, a burner inclosed by the collar and resting on said last mentioned flange, said burner being provided with a central opening and a series of orifices around said opening, and a cap resting on the burner within said series of orifices and covering said central opening said cap being provided with a series of openings.

In testimony whereof I ailix my signature, in the presence of two witnesses.
