Improvement in Gas-burners.
I, SAMUEL BERNSTEIN, a Citizen of the United States, Manufacturer, residing
at 82, West Broadway, City and State of New York, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
-
The subject of my invention is a burner for incandescent gas-light, simple and
cheap in construction and combining with the body of the burner, made prefer-
ably of metal cast in one piece and bent to one side above, the useful and essential
elements hereinafter described. The construction is shown in the, accompanying
drawings. Figure 1 shows a complete incandescent gas-lamp having a hood H
suspended over the burner. Figures 2 and 3 show that part of the complete
burner to which my invention particularly relates. Figures and 3 are alike,
except that in Figure 2 the passage P1 is open and the by-passage P1 is closed,
while in Figure 3 the closure of the passage P¹ has opened the by-passage P.
In Figures 1, 2 and 3, X is the body of the burner. A is a regulating-pin,
which operates vertically and centrally with the tube B of the Bunsen burner O
above, shown in Figure 1. In Figures 2 and 3, C is a plug having a passage P,
cut on its lower side and so adjusted that, just before the passage P is closed,
by the turning of the plug C, the by-passage P" becomes open. In Figures 2
and 3, represents, in the body of metal X, the main gas-inlet, which has the
usual threads for screwing the burner to the fixture. In Figures 1, 2 and 3,
E is a screw by which the supply of gas through the by-passage P can be
increased, diminished or shut off. In Figures 1, 2 and 3, F is the tube of a pilot
burner screwed into the 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 hood H. About the tube B of the Bunsen burner O, the
air-shutter K revolves. The body of metal-X, within which are contained the
threaded main gas-inlet. D, the passage 1, the by-passage P1; the plug C with
the passage P, the regulating-pin A, and the regulating-by-passage screw E, is
made of metal cast in one piece and is not straight, but bends 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 rendering the regulating-pin A
accessible and easily adjustable. The foregoing combination and arrangement
of elements useful and essential in a burner for incandescent gas-light render the
mechanical construction simple and convenient, reduce materially the cost of
manufacture and produce a burner of improved efficiency.
Heretofore, in burners for incandescent gas-light, great difficulty has always
and for a long time been experienced in securing an efficient and convenient
adjustment of the supply of the gas used to the Bunsen burner and in securing an
efficient admixture of air and gas in the air chamber of the Bunsen burner. The
supply of the gas used in the Bunsen burner has, heretofore, 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 supply of the gas used

page_text: 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 1), the passage P of the plug C and the
passage P1, is efficiently and conveniently 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 lit above forms a highly efficient Bunsen
flame which renders the hood H incandescent. By revolving the plug C, by means
of the rod and chain attachment Y shown in Figure 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 pilot burner R; but before the Bunsen
flame has been extinguished the gas is supplied to the pilot burner and becomes
ignited by the Bunsen flame at the orifice V. The supply of gas to the pilot
burner is regulated by the screw E which regulates the by-passage P.
flame of the pilot light at V is small and does not come in contact with the hood H;
the subdued light of the pilot burner is desirable not only to re-ignite 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 re-ignited the pilot
flame is extinguished.
The
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In an incandescent gas-burner, the combination, with and within the body
of the burner, of 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, the combination, with and within the body
of the burner made of metal cast in one piece, of 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.
3. In an incandescent gas-burner, the combination, with and within the body
of the burner made of metal cast in one piece and bending or extending to one
side above, of 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, the combination, with and within the body
of the burner, which bends or extends to one side above, of a passage supplying
gas to a Bunsen burner, a pin passing through the lateral extension and regu-
lating 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 supply-
ing 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.
