UNITED STATES THOMAS W. CORKELL, OF CHICAGO, ILLINOIS.

REGULATOR FOR GAS-HEATER BURNERS.

Specification of Letters Patent.

Patented Feb. 14, 1922.

Application filed April 30, 1920. Serial No. 377,847.

To all whom it may concern:

Be it known that I, THOMAS W. CORKELL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful Improvements in a Regulator for Gas-Heater Burners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

As is well known, in the operation of gas burners of the Bunsen type there is often an objectionable roaring when the pressure is high, which has ordinarily been remedied by covering one or more of the'air inlets with the fingers as a test, then when the proper inflow or air has been determined, by pasting the members shut with gummed paper or the like. This method is obj ectionable for several reasons; it is likely to burn the fingers of the operator, and as the gas pressure varies considerably at times, it may be necessary to; remove and replace the gummed paper at frequent intervals.

This invention relates more particularly to an improved means whereby the rate of inflow of air may be varied at the will of the operator practically instantaneously and with great ease.

It is an object of this invention to 'provide an air regulating means which can be shifted through a wide range at frequent intervals and with a minimum of trouble.

A further object of the invention is to provide a regulating means which can be adjusted with great precision and accuracy while the burner is in operation, thereby ensuring the best results.

Other and further important objects of this invention will be apparent from the disclosures in the drawings and specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is an elevation of a form of gas jet heater with the device attached.

Figure 2 is an enlarged elevation of the base of the burner showing the device thereon in inoperative position.

Figure 3 is a sectional view on the line 3-3 of Figure 2.

Figure 4 is a view of the regulator as detached from a burner.

Figure 5 is a sectional view taken on the line 55 of Figure 2.

Figure 6 is a side elevation of another modification of the device as applied to a burner.

Figure 7 is a section on the line 7-7 of Figure 6.

V Figure 8 is a section on the line 88 of Figure 6.

As shown on the drawings:

The reference numeral 10 indicates the tube of a burner of the Bunsen type, in this case applied to a device for heating rooms by means of having the flames issuing from the orifices 11 impinge on a plate 12, and the heat radiated therefrom is directed downwardly by means of a polished reflector 13. This idea forms no part of the present invention, which consists only in the regulator for the influx of air to the burner, and has been applied to this particular heater merely for purposes of. illustration. It is understood that the regulator can be applied to any burner of like type. I v

The regulating device of this invention consists essentially of a band 14 of any resilient metal which is slidable and revoluble on the tube 10 and held in adjusted position by means of the bolt 15. The band 14 is also provided with an inwardly projecting lug 16, which projects into one of the air inlets 17 of the tube 10.

In the modification shown in Figure 5, the bolt 15 is omitted, the resiliency of the band 14 being relied upon to hold same in adjusted position. Figures 6, 7 and 8 disclose a band 14 having apertures 18 corre sponding in sizeto the apertures 17 and adapted to fit over the same. The band 14 is preferably constructed of one piece and is adapted to revolubly encircle the tube 10, whereby the apertures 17 may be partly or wholly closed by varying the position of the apertures 18. A lug 19 is provided which projects into one of the openings 17 and thereby holds the band 14 in position.

The operation isas follows:

Any adjustment of the influx of air through the holes 17 may be made by a vertical movement of the band 14 on the tube 10, it being then fixed in position by tightening the nut on the bolt 15. The resiliency of the band 14 further serves to retain same in adjusted position, while in all cases the lug 16 prevents any displacement of the band from its operative position. The band 14" is l'OlJELlCEXl in it longitudinal plane and the working size of the aperture lZ-thus determined.

I claim as my invention:

1. A gas burner including a tube, a resilient band encircling said tube 21nd capable of sliding movement over the surface of the tube in all directions, and means integral with the band, cooperating with the tube to limit the movements of the band, and means cooperntingwith the resilient character of the band for fixing the band in any position to which it is moved.

1 ,eoee 14 2. A gas burner regulator comprising :i band encircling the burner tube and adapted to slide thereon said band being provided with a bolt for locking same in adjusted position, and an inwardly projecting lug for maintaining same in normal working position.

In testimony whereof I have hereunto subscribed my name in the presence of two.

subscribing Witnesses.
