JAMES F. HOPPER, 0F SHERMAN, TEXAS, ASSIGNOR OF ONE-HALF TO DANIEL K.

PENN, OF SHERMAN, TEXAS.

GAS GENERATOR AND BURNER.

Specification of Letters Patent.

Patented Mar. 23, 1915.

Application filed December 11, 1914. Serial No. 876,630.

To all whom it may concern Be it known that 1, JAMES F. HOPPER, a citizen of the United States, residing at Sherman, in the county of Grayson and State of Texas, have invented certain new and useful. Improvements in Gas Generators and Burners, of which the following is a specification.

My invention relatesto a combined gas generator and burner, and it particularly relates to a device of this character adapted to be used in connection with ordinary cooking and heating stoves, kitchen-ranges, &c., for burning kerosene oil, but also adapted for other uses.

An object of the invention is to provlde a device of this character which may be fitted into the firebox and located above the grate of stoves of diiferent sizes, or having different sized fireboxes, with equal efiiciency.

Another object and essential characteristic feature of the invention is to provide a device of this character having a return pipe extending from the gas generating coil to, and communicating with the top of the oil supply tank, into which tank any excess of gas generated in the coil when in operation is conducted and it attains considerable pressure; causing a torch-like flame beneath the coil and thereby assisting combustion, giving the device a greater breadth of utility and adaptation.

A still further object is to provide a fuel supply tank communicating with both the liquid supply pipe and the gas inlet p pe and having a novel arrangement insuring the filling of the tank only to a predetermined point, leaving space above the oil for the receipt of gas when the burner is in use, and also, after the burner has first been used the supply of gas retained in the tank enables the burner readily started and heated when gas will again be generated.

Other objects and advantages will be hereinafter set forth and also to acquire a knowledge of the details of construction and means for effecting the results reference is to be had to the following description and draw: ings hereto attached. I r

In the accompanying drawings which are made a part of this specification, Figure 1, represents a front elevation of a stove w th the burner applied and having a section broken out through which the burner may be seen, and Fig. 2 is a plan view of the same.

Referring more particularly to the drawings in which similar reference numerals designate corresponding parts throughout the several views, the different structural features of the burner are preferably substantially as hereinafter described. HOW- ever, they are susceptible to a greater or less degree of modification with reference to the spirit of the invention.

In the drawings, the numeral 1 indicates a stove of ordinary construction; 2 the usual fire box in which is located the gas generating pipes which comprise a combined horizontally disposed superheating coil 3, located at one end and near the top of the firebox; from the outer convolution of this coil a pipe 4 extends to near the opposite end of the box and is there connected by a transversely disposed loop 5 to a downwardlyinclined pipe 6, that extends back to and through the end of the box and is connected. by a laterally disposed pipe 7 to a burner pipe 8, that enters the box and extends centrally beneath the coil to near the opposite end of the box, and thence upward and back again through the box, to and connected near the top of an oil tank 9. Centrally lo.- cated in the pipe 7 is a T, 10, provided with an angle valve 11 to which is connected an auxiliary burner pipe 12, closed at one end, that supplies gas to another burner supported thereby, when desired. From the inner convolution of the coil and connected in any usual manner to the bottom of the storage tank 9 is the oil supply or inlet pipe 13, provided with the usual controlling-valve 14, from which tank the supply of oil used with the present burner is taken.

The burner pipe 8 has a small perforation or jet on the top side at 15 where the oil is ignited, and the pipe 12 has a similar jet at 16. 17 and 18 are draft tubes and mixing chambers, they are apertured at their base and vertically supported on the respective pipes in any convenient manner. Perforations 19 are provided for the passage of air within the tubes. Secured to the generator pipe 8, by any proper means such as, for instance, eye bolts 20, are deflectors or spreaders 21, centrally located over the gas jets and adapted to spread the flame when the gas from the jets is burning.

The closed top of the oil tank 9 is perforated and provided with a tube 22, that extends dow" some distance within it, also a slight distance above the top of same, where it is closed by a cork 3; the tank is supplied with oil through this tube and its function is to prevent the tank being entirely filled with oil, thus insuring a chamber for gas when the burners are started. The pipe 8 is forked before entering the tank and communicates with it at two points, 2% and 25; the former having an automatic check valve 26 entering in the tank, and the latter a throttle valve 27, for regulating the outlet of gas as required.

in operation, liquid fuel passes from the supply tank through the supply pipe 13, and the quantity thereof is regulated by the valve 1%; the oil continues its course through the coil and other pipes and flows through the perforations 1-5 and ignited, thereby heating the coil and pipe sections to such an extent that the gas is quickly generated within the pipes, when the burning of the gas from the jets keeps the coil and pipes continually hot enough to continue the generation of the gas so long as fuel is admitted through the pipe. After starting the first burner, should more heat be required, the valve 11 may be opened and gas admitted to the jet 16, thus operating both burners. ithen more gas is enerated than is consumed by the ets, it flows around and back through the pipes and enters the vacant portion within the tank through the check valve 26, attaining desired density therein; and the same pressure being maintained in the pipes, exerts considerable force upon the burning jets; producing a torch-like flame of intense heat, also a perfect combustion which thoroughly utilizes all of the heat properties contained in the oil. When the operation of the burners is no longer required, the valves 1% and 2'? are closed, when suliicient gas will be retained in the tank to again start them Without the necessity of first flowing oil to the jets.

ll hat I claim is 1. In a gas generator and burner for stoves and the like, a tank, an oil supply pipe and generator pipes, the oil supply pipe connected with the bottom or" the oil supply tank, and one of the generator pipes having a jet opening therein, and said generator pipe extended to the top of the tank and connected thereto at two points forking therefrom, one of the said connections being provided with an inlet check valve, and the other with a throttle valve, tor the purpose specified.

The combination with a stove of a gas generator and burner, an oil supply tank apertured through the top and provided with a tube extending some distance downward Within it, and above the same to receive a cork, a generating coil and generating pipes located within the firebox 035 said stove and an oil supply pipe opening in the bottom of the tank and extending to said coil, and said generating pipes communicating with said coil and passing out of the box and to the top of the tank where it branches, entering the tank at two points; one of said branches being provided with a check valve and the other with a throttle, as and for the purpose specified.

In testimony whereof l afiix my signature in presence of two witnesses.
