Application 1116a November 16,1906. Serial No. 287,653.

To aZZ whom it may concern:

, Be it known that I, ALFRED H. Him PHREY, a citizen of the United States, resid.

ing-at New York city, in the State of New York, haveinvented certain new'and-useful.

inverted burners in which all of theburners are accessible and capable of independent adjustment; third, to provide an improved gas-lamp in which the burner or burners are properly supplied with air and at the same. time are fully protected; fourth, to provide an improved gaslamp having aninvertedburner or burners in which the liability of back lighting is reduced to a minimum; fifth, to provide an improved gas-lamp in which "the parts are eifectively protected from excessive heat from the burners; sixth, to provide in a gas-lamp having an inverted burner or burners an improved globe and shade support; seventh, to provide in a gas lamp an improved pilot-light and means for flashing the same eighth, to provide in a gaslamp an improved valvemechanism; ninth, to provide in a gas-lamp having aninverted burner an improved mantle-support.

Further objects and objects relating to structural details will definitelyappear from the detailed description to follow.

I accomplish the objects of myvinvention by the devices and means described in'the following specification.

The invention is clearly defined, and pointed out in the'claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which-.

Figure 1 is a detail-vertical section taken on a line corresponding to line 1 1- of Fig.- 2 of my improved. gas-lamp. Fig. 2 is a horizon- -tal section taken onaline corresponding to line 2 20f Fig. 1. Fig. 3 is an enlarged detail vertical section taken on a line corresponding to line 3 3 of Fig. 1, showing structural details and the arrangement of the burners.

Fig.4 is an enlarged detail vertical section taken on a line corresponding to line 4 40f Fig. 1, showing structural details of the taken .on'line5,5 of Fig. 4. Fig. 6 is a plan of the mantle-support;

In the drawings similar letters of reference refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines.

A pipe 6 is rovided for the other arm of the coupling 0 but this is preferably a blind pipe, so that only one valve, as D, is required to control the'delivery'of the gas, and at the same time the-valve is located close to the burners. v f

The gas-delivery ring is provided with ceive the delivery-nozzles b. The burnerburner-tubesare provided with suitable airports ,at.the baseopening about the delivery-v .nozzles and are arranged through suitable holes. provided therefor in the flangeA of i ,the chimney, so that the burnersB are-"lois indicate in Fig. 3 of the drawings. i.

In operation the-heated air and ases from the burners ass up-throughthe clnmney'and out under t e shield Jabove the same The burner and gas-deliVery pipes are protected from these-heated gases'so that they do not become unduly heated-,- which is-very "apt to cause back lighting; The burners are fully protected from draft, so that the flame is pro 'erly directed to: heat the entire mantle, an at the sa'me' time the desired supply of air is insured owing to the draft which is set upthrough the chimney. The burners being grouped about the chimney are inpositionso that the fresh air'isdraw-n up through the mantles, thereby insuring perfect combastion of thega'ses.

By arranging the burners in an inverted position there isnothing below the burners to obstruct the light or to'cast shadows. By

thus arranging the parts I- secure a lamp the candle-power of which is greatly in excess of the incandescent lam swhich have" heretofore'corne-t'o-my knowledge.

I have illustrated my Improved gas lamp in detail in the form preferred by me on ac.- count of its structural simplicity and economy and convenience in operation-and ad'- justment. I am-,however, aware that, it is capable of very great yari'at'ion in structural details wlthout departmgh om my invention.

Having thus described my invention; what I claim as new', and desire-to secureby' Letters Patent, is-
