Specification of Letters Patent.

Patented Oct. 18, 1921.

Application led September 28, 1.920. Serial No. 413,357.

To all f1.0 /tom t 'muy concern Be it known that I, J Amis B. SHERIDAN, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Burners; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to improvements .in gas burners, and particularly to burners used in gas cooking ranges.

It is a matter of common experience to users of gas stoves, particularly those users dependent on natural gas, that the pressure in the gas supply lines varies to such an extent that with the stove burner valves fully open only a small flame can be obtained. It has been found by experiment that the most efficient heating of a gas flame in a stove burner is obtainedby having the receptacle to be heated a small fraction of an inch above the tip of the flame. A difficulty encountered in the usual form of burner is that it is constructed so as to give eicient heating at ordinary pressures, but cannot be rendered effective when the pressure of the supply falls below (or rises above) the ordinary or normal pressure.

It is the primary object of the present invention to provide a burner adaptable for cooking ranges which may be easily and simply moved with relation to the support for holding a receptacle to be heated in such manner that the burner may be maintained at a position beneath the receptacle most suited for giving the most efficient result at varying pressures, and thus compensate to a great extent for the variations in pressure in the supply line.

My invention is also adapted for use when the gas pressure in the supply is normal but the valve or cock controlling the flow of gas t0 the burner is not Wide open. By proper adjustment of the burner, an economy in fuel consumption coupled with higher efficiency may be effected.

My invention is shown in the accompanying` drawings, in which,

igure 1 is a side elevation of a form of my invention, showing it adjusted for low supply pressure or at a position where the valve (not shown) is only partially open;

Fig. 2 is a similar view of the adjusting elements showing the burner tube in position for normal or nearly normal supply;

Fig. 8 is a top view of the burner; and Fig. el shows a modification which may be used.

In the drawings, A represents diagram-- matically the top of a stove provided with a burner opening, and B represents a kettle or receptacle to be heated.

Supported in any desired way beneath the top A of the stove is a mixer tube 5 having a mixer 6 and a vertical portion T. Telescoping over the vertical end T of the mixer pipe 6 is a. burner pipe S having an eccentric 'or goose-necked portion 9, to the upper end of which is supported an air-ring burner 10.

Secured a suitable distance below the top of the vertical portion 7 of the mixer pipe 6 is a projecting pin 11. The lower end of the telescoping part of the burner tube 8 is provided with a helical slot 12, the upper edge 13 of which is provided with steps, while `the lower edge 111 is smooth. The pin l1 is adapted to engage the bottom of the burner tube, as shown in .F ig. 1, to hold the burner close to the receptacle when the gas pressure is very low, or the control valve is turned to provide a low flame. Ey turning the burner tube 8, the pin 11 may be brought into engagement with one of thehorizontal edges or flat surfaces of the stepped portion 14, as shown in F ig. 2, and thus provide for intermediate adjustment between entreme low pressures and eXtreme high ones, the end of the slot forming the adjustment for use with the highest pressures.

By reason of the goose-neck or eccentric portion 9 of the burner tube, the ring burner, which is desirable for use in stoves because it permits passage of air up through the middle of the burner, may always remain centered beneath the burner opening in the top A, and concentric with the vertical axis of the sliding connection.

In the modification shown in Fig. 4, I have shown similar telescoping mixer and burner tubes, but instead of using a slot and pin as previously described, I use a convolute disk 15 having its edges flattened to form steps, which disk is pivoted to the vertical portion 7 of the mixer tube. The lower end of the burner tube 8 rests on the uppermost of the fiat surfaces or steps on the edge of disk 15. By turning the disk 15, for which purpose a button 16 may ,be provided, the burner tube may be raised or lowered.

Other modifications and changes may be suggested, and I do not limit myself to the exact construction and arrangement of parts described in the embodiments shown in the drawings, nor do I limit the application of my invention to use in cooking stoves, as obviously it may be useful in other heating de VlCeS.

l/Vhat I claim is:

l. An adjustable burner for stoves c0111- prising a mixing tube, a burner tube tele scoping with the mixing tube, an eccentric portion on the burner tube supporting a ring burner in such manner that the ring burnermay be always centered over the telescoping connection, and means ior holding the burner tube in any one of a plurality or' adjusted positions.

2. A burner comprising a burner ring, a burner tube connected to the ring, a mixer tube communicating With the burner tube through a vertically adjustable connection, means for holding the burner tube in any one of a plurality otadjusted positions, and means in the burner tube for holding the ring burner concentric with the vertical each oi which portions when in operative position holds the burner tube in a different vertical position, and means on the other tube for engaging that. step of the series which is in operative position, whereby the burner tube may be selectively held in a plurality of different positions.

A burner comprising a vertically movable burner tube and a stationary mixer tube, a sliding telescoping connection between the burner tube and mixer tube, the telescoping end of the burner tube being provided with a helically arranged slot, a pin on the mixer tube` adapted to engage the edges of the slot, and means on one edge or' the slot adapted to be brought into selective engagement with said pin to support the burner tube in any one of a plurality yof different vertical positions.

6. A burner comprising a vertically movable burner tube and a stationary Vmixer tube, a sliding telescoping connection between the burner tube iand the'mixer tube, the telescoping end of the burner tube being provided lWith a helically arranged slot, a pin on the mixer tube adapted to engage the edges oit the slot, and a series of steps arranged on the upper edge of said helical slot7 said steps being adapted for selectiveengagement with the pin to support the burner tube in any one of a plurality of different vertical positions.
