REGULATOR FOB OIL-GAS BURNERS.

Specification of Letters Patent. Patented Jain. 1L5, 191%.

m i licatlon filed April 30, 1917. Serial No. 165,505.

burners which convert oil into gas and burn.

the gas, and. particularly to such oil-gas burners as are adapted to be used in stoves and ranges for cooking purposes, and its object is to control the admlssion to the mixing chamber of oil-vapor and air.

To this end my invention consists 1n the construction and combination of parts forming a regulator for oil-gas burners here1nafter more fully described and particularly stated in the claims, reference being had to the accompanying drawings in wh1ch-- Figure 1 represents in vertical section,

partly in side elevation, a regulator for oilgas burners according to my invention.

Fig. 11 is an under side View of the regulator attaching web. v

Numeral 3 represents the base pan, 4 the mixing chamber comprising a floor 5, an outer wall 6, an inner wall or intake tube 7, a dome-shaped cap 8, and a perforated burner 9. The mixing chamber is mounted on legs 10, standing in the pan 3. A retort 11, surrounds the mixing chamber, resting on brackets 12, thereof and is connected at one end with a source of oil supply, and at the other end 13, it delivers into the tip 14:. A nozzle 15, with a very fine outlet 16, delivers a jet 17, of oil spray into theintake tube 7. A cleaner for the outlet 16, is connected in a usual manner to be operated by the wire lever 18. A ate tube 19, is fitted to telescope with the intake tube 7, and is connected with a regulating screw 20, by a web 21, that is secured to the gate tube. The screw 20, has a neck turning freely in the web 21, and a head 22, for lifting engagement therewith.

A binding nut 23, may be used to hold the screw fixed at any desired point. Asapply of oil is usually kept in a reservolr or tank at a safe distance from the stove and is carried to the retort 11, by a very small pipe which is provided with a throttle valve whereby the supply of oil may be regulated according to the amount ofheat desired, and the oil is delivered under pressure by forcing air into the tank. In operation, the retort 11, is to be heated to start it to vaporizing the oil in it by burning alcohol or other combustible fluid in the base-pan 3. The expansion of the vapor drives it as a jet 17, up through the intake tube 7 drawing with it. air into the mixing chamber 4. There the current is deflected downward by contact with the internally concave cap 8, to

pass under the edge 24, then over the outer.

wall 6, to the annular space 25, from which it isdischarged through many perforations 26, inthe burner 9, and burned in a continuous blaze after being ignited. Dark blue color of the blaze indicates the greatest heat in burning oil-gas, and this can be produced by mixing air and oil vapor in due proportions, which may be done by operating the gate 19, by means of the screw 20. If that screw be turned upward it will draw the 1 gate 19, nearer and nearer to the dome 8 thereby gradually shutting olf the inlet of air and causing the flame to turn greenish and finally yellow, giving of]? dense smoke. If the screw be turned downward from the blue burning point the blaze will gradually fade in color and finally be blown out by the admission of too much air. Whether little or much oil is being admitted to produce little or great heat, the blue color of the flame should be always maintained by properly fixing the gate by the adjusting screw as described. The head 22, of the screw is shaped as a downward pointed cone, and the dome 8 is shaped as a curved fillet 27, depending around the screw 20, to give the incoming air and vapor an outward flare so it may follow the downward turn of the dome 8, in even curves insuring a smooth steady delivery of gas to the flame. By using a long slianked screwdriver the screw 20, may be adjusted while the stove is burning, without discomfort to the hand of the operator, thus enabling this heater to be regulated to the greatest nicety of economy.

I claim:

1. In a regulator for oil-gas burners, a mixing chamber comprising an outer wall, a central-intake tube, a perforated burner around the outer wall and a dome-shaped cap-resting on the said burner; a tubular gate telescoping with the intake tube; a screw passing down through the cap and engaging the said gate, and means for spraying oil up into the intake tube.

2. In a regulator for oil-gas burners, a

mixing chamber having an intake tribe; a tubular gate telescoping with the intake tube; a dome-shaped e p; a screw depending from the cap an engaging the said gate, the lower end of the screw being pointed, and a curved fillet of the cap depending around the said screw.

3. In a regulator for oil-gas burners, a mixing chamber comprising an intake tube and a dome-shaped cap; a tubular gate telescoping with the intake tube, and communicating means passing through the said cap to raise and lower the gate.

4. A regulator for oil-gas burners having a mixing chamber; an intake tube; a tubular 15 gate telescoping with the intake tube and rising above the top thereof; a dome-shaped cap over the gate and means for moving the gate toward and away from the cap to decrease or to increase the inlet for air and 20 oil-vapor.

In testimon ,whereof I affix my signature in presence of two witnesses.
