SPECIFICATION forming part of Letters Patent No. 656,005, dated August 14, 1900. Application fi1ed A ri119 1900. serial No. 18, 448. (No model.)

To all whom, it may coiwei mg,

Beit known thatLOHARLEs F:ALLEN,a citizen of the United Statcs,residin g at Massillon,"

ing to be a full, clear, and exact description.

of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to'lamps, and more particularly to lamps of a high candle-power, which may be used for street or hall lighting or house-lighting.

The object of the invention is to provide a lamp of this character which shall be simple of construction, durable in use, comparatively inexpensive of production, and which will produce a powerful light with a minimum expenditure of gas.

In the accompanying drawings, Figure 1 is a side elevation of the complete lamp,showing the globe and reflector in place. Fig. 2 is an enlarged side elevation. Fig. 3 is an enlarged detail view of the burner-head and the parts immediately associated therewith.

Fig. lis a vertical sectional view through the burner-head, the mixing-chamber, and the regulating-valve. Fig. 5 is a cross-sectional view through the mixing-chamber and valve on line 5 5 of Fig.2, and Fig. 6 is a cross: sectional view through the burner-head on line 6 6 of Fig. 2. r

In the drawings, 1 denotes the body of the burner-head, which is provided with radial upwardly-extending burners 2, which communicate with a centrally-disposed downwardly-projecting nipple 3. The upper portion of the head is provided with a vertical nipple 4, arranged between the burners 2 and communicating with'two divergent by-passes 5, which, together with said burners and nipples, form an integral casting.

6 denotes a Y-pipe the-branches 7 of which are connected to the by-passes 5 by vertical pipes 8 and the body portion of which is provided at its upper end with a jet-orifice 9, controlled by a needle-valve 10.

11 denotes a mixing-chamber the upper end of which is screwed to the nipple 3 and the lower end of which surrounds the upper end of the Y-pipc 6. The mixing-chamber is provided with a series of openings 12.

13 denotes a valve which is in the form of a sleeve and which is loosely mounted upon the mixing-chamber and is provided with openings 14, which by turning the valve may be made to register with the openings in the mixing chamber to permit of the passage of airinto said chamber. Secured to said valve, preferably at its upper end and entirely surrounding the valve, is a hood 15, which serves the twofold function of means for, rotating the sleeve and to prevent drafts or sudden gusts of air passing upward beyond the holes in the valve which would cause the light to flicker.

16 denotes an inlet-pipe which is screwed onto the nipple 4 and is provided with a mantle-supporting head 17, which is held in adjustment to said pipe by a set-screw 18. The head is provided with pivoted arms 19,

from which the upper ends of the .mantles are suspended, while the lower ends of the mantles embrace the burners 2. It will thus be noticed that from a point below the mantle supporting head the mantles entirely surround the inlet-pipe, and the heat therefrom thus serves to rarefy or vaporize the gas or oil passing through said pipe into the burnerhead. I

20denotes a globe supported in a globeholder 21 and secured to the lower end of the Ypipe,and 22 denotes an ornamental casing attached to the supply-pipe and provided at its lower end with a reflector 23.

24 denotes a valve in the supply-pipe, and 25 denotes an operating-lever provided with chains by means of which said valve may be mixing-chamber, which mixes with the gas or vapor and passes therewith upwardly through the centrally and vertically disposed nipple 3. From this point the gas passes to the burners 2, from which point it escapes into the mantles. A gauze diaphragm 26 is arranged in each burner.

Various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a lamp of the character described, the combination, with a supply-pipe, of a burnerhead provided with radiating burners and with downwardly-extending by-passes and vertical upwardly and downwardly projecting nipples, one of which nipples communicates with the supply-pipe and the by-passes, and the other with the burners, a Y-pipe arranged below the burner-head, pipes establishin g communication between the branches of the Y-pipe and by-passes, and the mixingchamber connected to the downwardly-extending nipple, substantially as described.

2. In a lamp of the character described, the combination, with asupply-pipe, of a burnerhead having radial upwardly-extendingburners, by-passes and upwardly and downwardly projecting nipples, one of which communicates with the supply-pipe and the by-passes, and the other with the burners, a Y-pipe arranged below the burner-head, pipes con necting the Y-pipe with the by-passes, a mixingchamber located between said connectingpipes and in communication with the Y-pipe and downwardly-projecting nipple, a valve for controlling the escape of gas through the Y-pipe into the mixing-chamber, and a valve for regulating the supply of air to the mixingchamber, substantially as described.

3. In a lamp of the character described, the combination, with a supply-pipe, of a burnerhead provided'with radiating burners and with by-passes and vertical upwardly and downwardly projecting nipples, one of which nipples communicates with the supply-pipe and the by-passes, and the other with the burners, a Y-pipe, pipes establishing communication between the branches of the Y- pipe and the by-passes, a mixing-chamber located between said connecting-pipes and secured to the downwardly-extending nipple and Y-pipe, and mantles supported above the burners, substantially as described.

4. In a lamp of the character described, the combination, with a supply-pipe, of a burnerhead having radial upwardly-extending burners, down wardly-extendin g by-passes and upwardly and downwardly projecting nipples, one of which nipples communicates with the supply-pipe and the by-passes, and the other with the burners, a Y-pipe located below the burner-head, vertical pipes connecting the branches of the Y-pipe with the said downwardly-extending by-passes, a mixing-chamber located above the Y-pipe and secured thereto and to the downwardly-extending nipple, a valve for controlling the escape of gas from the Y-pipe into the mixing-chamber, a valve for regulating the supply of air to the mixing-chamber, and a hood surrounding the air-valve, substantially as described.

5. In a lamp of the character described, the combination with a burner-head provided with radiating burners and with by-passes and vertically upwardly and downwardly projecting nipples, one of which communicates with the by-passes and the other with the burners, of a Y-pipe, pipes establishing communication between the branches of the Y-pipe and by-passes, a mixing-chamber secured to the downwardly-extending nipple, a supply-pipe connected to the upwardly-extending nipple, a mantle-supporting head secured to said supply-pipe, and mantles connected to said head and surrounding said pipe and engaged at their lower end with the burners, substantially as set forth.

6. In a lamp of the character described, a burner-head provided with a series of upwardly projecting radial burners, downwardly-projecting by-passes adapted for connection with pipes leading to a mixing-chamber, and central upwardly and downwardly projecting nipples, one adapted for connection with a supply-pipe and in communication with said by-passes,and the other adapted for connection with a mixing-chamber and in communication with the bu rners,all formed of a single piece of metal, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
