GAS-REGULATING BURNER.

SPECIFICATION forming part of Letters Patent No. 501,459, dated July 11, 1893.

Application filed February 29, 1892. Serial No. 423,275- (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES S. FORD, Sn, a citizen of the United States, residing at Eden, in the county of Bucks and State of Pennsylvania, have invented a new and useful Improvement in Gas-Burn ers, of which the following is a specification.

My invention relates to an improvement in gas regulating-burners.

My object in this invention is to enable those interested, to regulate the flow of gas at the burner, in such a manner that the volume escaping through its tip when once gaged, cannot be changed without a device adequate r 5 to remove the burner from its connection on the fixture. This is accomplished by the burner being screwed upon the nozzle, said burner carrying the cone, and chamber, and minute sphere. As the burner is screwed upon the nozzle, the said sphere enters the bore of the nozzle followed by the cone which gradually closes the bore in the nozzle, thus regulating the amountof gas which will bein the ratio to the relative position of the cone 2 5 v in the bore. The object of the minute sphere on the end of the pendent cone, is to serve as a grip piece, with which to insert, or withdraw the annular chamber from the central bore of the burner. The object of the annu- 0 lar chamber is to serve as.a receptacle for a packing composed of fibrous material, such as cotton, asbestus, or any of the. known substances of like nature, that will best answer the purpose of assisting in equalizing and 3 5 steadying the pressure of the current of gas permitted to flow through its orifices to the tip to be consumed for purposes of illumination.

I am aware that burners are constructed so as to regulate the flow of gas at the burner with cotton, and other fibrous substances, but

the difi'iculty has been in renewing the same without destroying the burner.

Previous to the attachment of the burner,

to the nozzle of a fixture, the annular chamher is packed loosely, with fibrous material,

such as cotton, or-asbestus, to assist in equalizing and steadying the amount of volume of gas permitted to flow through its series of vertical orifices to the outlet tip to be ig 5o nited for illuminating purposes. This annular chamber and its pendent cone are then inserted within the skeleton burner, and adjusted by hand, in either an elevated, or depressed position to regulate the volume of the current of gas desired to flow to the tip, through the orifices. The burner is then tightlyscrewed upon the nozzle, thus rendering outside manipulation impossible to control the volume of gas.

I provide my burner with a fixed washer, for the reason, that it forms a tight joint on the fixture, and is an essential adjunct in combination with the internal working of my device, and to insure against any possible leakage.

In order to enable others skilled in the art to which my invention appertains, to make and use it, I will now proceed to describe its construction and operation.

I construct an ordinary skeleton gas burner, with a screw thread formed in its lower bore, and an outlet tip placed in its upper extremity. Into the space of said bore between the thread and tip, I place a closely fitting annular chamber, with a series of vertical orifices through its bottom, and provided with a pendent cone extending downward and terminatin g in a minute sphere. On the lower edge of said skeleton burner, and encircling its bore, I fasten a flexible washer by means of a cohesive cement, the whole in combination forming one solid gas burner, devoid of any other external movable parts, except the burner itself, which when screwed on to the nozzle of the fixture'accomplishesthe results herein stated and described, for the purpose set forth.

In the accompanying drawings which make a part of this specification, Figure 1, is avertical section of my improved burner. Fig.2, 0 is a view of the annular chamber C, cone D, and minute sphere, e, inverted. Fig. 3, is a view of the nozzle E, of a gas fixture, partly in section, showing the annular chamber C, pendent cone E and minute sphere e.

Like letters of reference in all the figures indicate the same parts.

A, is the cylindrical skeleton of the burner, having the screw thread I), cut in the lower end of the bore. B, is the usual outlet tip in its I00 upper end. C, is the annular chamber situated therein, having a series of orifices b, or pas sages in its bottom d, for the passage of gas to the exit. This chamber 0, has a pendent cone D, extending downward from its base d, and terminating in the sphere e. this annular chamber is to serve as a recepta cle for packingas before pointed out, that can be readily renewed when fouled with impurities, without impairing the usefulness of the burner. The pendent cone D, with its sphere e, descending vertically from this annular chamber, serves as a cut OE, and regulator of gas to the burner, as will be seen in Fig. 3, where it is shown as gradually impinging in the bore of the nozzle E. The pendent cone D, with its sphere e, and annular chamber 0, are formed of one piece of metal, and operate in combination with the skeleton burner A,

T e O jec p through its bottom cl, and surrounding the upper end of the cone D, in combination with the skeleton burner A, substantially in the manner, and for the purpose herein shown CHARLES S. FORD, SR.

' and described.
