GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 653,464, dated July 10, 1900.

Application filed September 26, 1899. Serial No. 731 ,763. (No model.)

10 to whom it may concern.-

Be it known that I, SAMUEL BERNSTEIN, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Gas-B urners,of which the following is a specification.

My invention relates to the construction of gas-burners, and especially to the construction of burners for incandescent gas-lights.

The object of my invention is to devise a burner for incandescent gas-lights simple and cheap in construction and in which there are provided within the base-piece of the burner, which preferably is made of metal cast in one piece and bends or extends to one side above,

a main gas-inlet provided with threads to enable the burner to be screwed to the fixture, a passage supplying gas to a Bunsen burner, a pin accessible to the fingers of the hand and readily adjustable, regulating the-supply of gas through the passage to the Bunsen burner and operating vertically and centrally with the tube of the Bunsen burner, a bypassage supplying gas to apilot-tube leading, preferably, through the tube of the Bunsen burner to a pilot-burner, a screw regulating the supply of gas through the by-passage to the pilot-tube, a plug or gas-cock by which the flow of the gas from the main gas-inlet can be turned from the passage to the Bunsen burner to the by-passage to the pilot-tube, extinguishing the Bunsen flame and igniting the pilot-flame, or vice versa, as hereinafter more particularly described.

The construction of the burner is shown in the accompanying drawings.

Figure 1 shows a complete incandescent gas-lamp having a mantle or hood H suspended over the burner. Figs. 2 and 3 show that part of the complete burner of the gaslamp shown in Fig. 1 to which my invention particularly relates. Figs. 2 and 3 are alike, except that in Fig.2 the passage P, supplying gas to the Bunsen burner O, is open and the by-passage P, supplying gas through the pilot-tube F to the pilot-burner R, is closed, while in Fig. 3 the closure of the passage P, supplying gas to the Bunsen burner O, has left open the by-passage P, supplying gas through the pilot-tube F to the pilot-burner R.

In the drawings, X is the base-piece of the burner. A is a regulating-pin which operates vertically and which is central with the tube B of the Bunsen burner 0 above. (Shown in Fig. 1.)

In Figs. 2 and 3, C is a plug having a passage P, which is cut on the lower side of the plug and which is so adjusted that just before the passage P, supplying gas to the Bunsen burner O, is closed by the turning of the plug 0 the by-passage P, supplying gas through the pilot-tube F to the pilot-burner R, becomes open.

In Figs. 2 and 3, D represents in the basepiece or body of metal X the main gas-inlet, which has the usual threads to enable the burner to be screwed to the fixture.

In the drawings, E is a screw by which the extent of opening of the by-passage P can be regulated and the supply of gas through the by-passage P increased, diminished, or shut off.

In the drawings, F is the tube of a pilotburner R, screwed into the base-piece or body of metal X at G and extending upward through the tube of the Bunsen burner to a point V near the extremity of the Bunsen burner and within the mantle or hood H. About the tube B of the Bunsen burner O the air-shutter K revolves.

It will be seen from the drawings that the base-piece or body of metal X, which contains the threaded main gas-inlet D, the passage P, the by-passage P, and the plug 0, with the passage P,and into which are screwed the regulating-pin A, the regulating by-passage screw E, and the tube F of the pilotburner R, is made of metal cast in one piece. It'will also be se'en'from the drawings that the base-piece or body of metal X is not straight, but bends or extends above to one side, thereby enabling the regulating-pin A to operate vertically and centrally with the tube B of the Bunsen burner 0 above and at the same time rendering the regulatingpin A accessible to the fingers of the hand, and therefore readily and easily adjustable.

The foregoing combination and arrangement of elements useful and essential in a burner for incandescent gas-lights render the mechanical construction of the burner simple and convenient, reduce materially the cost of construction, and produce a burner for incandescent gas-lights of improved efficiency.

In order to use a gas-burner with gases of different kinds and with gases of Varying pressures for incandescent gas-lighting, it is necessary to regulate accurately the supply of the gas used. IIeretofore in burners for incandescent gas-lights great difficulty has always and for a long time been experienced in securing an eificient and convenient adjustment of the supply of the gas used to the Bunsen burner and in securing an eiiicient admixture of air and gas in the air-chamber of the Bunsen burner. Heretofore the supply of the gas used in the Bunsen burnerhas been determined by a perforated disk. The perforations of the disk have been made small or large according to the pressure of the gas estimated at the time of adjusting the burner to the fixture for use. By this method no regulation of the supplyof the gas used can be had at the disk while the burner remains adjusted to the fixture for use. This is a serious difficulty in incandescent gas-lighting.

The mode of operation of my invention is as follows: The supply of gas passing through the main gas-inlet D, the passage P of the 7 lug O, and the passage 1 is efficiently regulated at the orifice I by raising or lowering vertically the regulating-pin A. After passing through the orifice I the gas mingles in the tube of the Bunsen burner O with the air, which is regulated by an air-shutter, such as K, and when lighted above forms a highly-efficient Bunsen flame which renders the mantle orhood H incandescent. IVhen the light radiating from the incandescent mantle is not desired, by revolving the plug 0 by means of the rod-and-chain attachment Y (shown in Fig. 1) the course of the gas is changed from the passage P, leading to the Bunsen burner O, to the by-passage P, leading through the pilot-tube F to the pilotburner R; but before the flame of the Bunsen burnerhas been extinguished the gas is supplied to the pilot-burner and becomes ignited at the orifice V from the flame of the Bunsen burner. The supply of gas to the pilot-burner is regulated by the screw E, which regulates the by-passage P. The flame of the pilot-light at V is small and does not come in contact with the mantle H. The incandescence of the mantle therefore ceases entirely when the Bunsen flame has been extinguished, and in its place appears the subdued light of the pilot-burner, which is desirable not only to reignite the Bunsen flame when the incandescent light of the mantle is again desired, but is desirable also for use as a night-light. When the Bunsen flame is reignited, the pilot-flame is extinguished. Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. In an incandescent gas-burner, a basepiece of the burner provided with a passage supplying gas to a Bunsen burner, a pin regulating the supply of gas to the Bunsen burner, a by-passage supplying gas to a pilot-tube and a plug by which the flow of the gas can be turned from the passage to the Bunsen burner to the by-passage to the pilot-tube and vice versa, substantially as described.

2. In an incandescent gas-burner, a basepiece of the burner made of metal cast in one piece and provided with a-passage supplying gas to a Bunsen burner, a pin regulating the supply of gas to the Bunsen burner, a by-passage supplying gas to a pilot-tube and a plug by which the How of the gas can be turned from the passage to the Bunsen burner to the by-passage to the pilot-tube and vice versa, substantially as described.

3. In an incandescent gas-burner, a basepiece of the burner made of metal cast in one piece and bending or extending to one side above and provided with a passage supplying gas to a Bunsen burner, a pin passing through the lateral extension and regulating the supply of gas through the passage to the Bunsen burner and operating vertically and centrally with the tube of the Bunsen burner, a by-passage supplying gas to a pilot-tube and a plug by which the flow of the gas can be turned from the passage to the Bunsen burner to the by-passage to the pilot-tube and vice versa, substantially as described.

4. In an incandescent gas-burner, a basepiece of the burner which bends or extends to one side above and which is provided with a passage supplying gas to a Bunsen burner, a pin passing through the lateral extension and regulating the supply of gas through the passage to the Bunsen burner and operating vertically and centrally with the tube of the Bunsen burner, a by-passage supplying gas to a pilot-tube and a plug by which the flow of the gas can be turned from the passage to the Bunsen burner to the by-passage to the pilot-tube and vice versa, substantially as described.
