Improvements in Bunsen Burners.
I, DAVID REID, Instrument Maker, of 18, Cambridge Street, in the County
of the City of Glasgow, North Britain, do hereby declare the nature of this in-
vention to be as follows:-
This invention relates to improvements in Bunsen burners and has for its
object the saving of gas in the use of such burners.
In carrying out my invention I provide a bye-pass from which a small pipe
is brought to the top of the burner and in the main pipe of the burner I provide
a stopcock, which is automatically closed, by a spring or otherwise, when the
burner is not required. A small flame is then left in the small tube from the
bye-pass so that when the burner is required for use and the stopcock is opened
the gas will be ignited.

COMPLETE SPECIFICATION.
Improvements in Bunsen Burners,
I, DAVID REID, Instrument Maker, of 18, Cambridge Street, in the County,
of the City of Glasgow, North Britain, do hereby declare the nature of this in-
vention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement;-
--
This invention relates to improvements in Bunsen burners and has for its
object the saving of gas in the use of such burners.
In carrying out my invention I provide a bye-pass from which a small pipe
is brought to the top of the burner and in the main pipe of the burner I provide
a stopcock, which is automatically closed, by a spring or otherwise, when the
burner is not required. A small flame is then left in the small tube from the
bye-pass so that when the burner is required for use and the stop cock is opened
the gas will be ignited.
In order that my invention may be properly understood and readily carried
into effect I have hereunto appended one sheet of drawings, of which,
Figure 1 is an elevation partly in section of the burner.
Figure 2 is a plan.
In the main pipe A of the burner a valve B is provided, the shank 6 of which
is brought through and terminates in a small platform b¹. A spiral spring C

page_text: round the shank of the valve keeps the valve shut unless some weight or pressure
is applied to open the valve. From the main pipe on the gas supply side of
the valve a bye-pass D is brought up through the vertical tube of the burner and
terminates a little above the top of the burner. Thus the bye-pass can be kept
lighted even when the valve is shut. In the drawing a frame for carrying a
chemical dish or other article to be heated is shown hooked on to an arm. E, and
supported on the platform.
When the weight of the chemical dish or other article is put on this platform
the valve is opened and gas is admitted to the burner, and when the weight is
removed, the valve is closed by the spiral spring. The frame may be removed
and a weight applied direct to the platform, or if the burner is being held in the
hand, the valve can be kept open when required by the thumb. The outlet F
for the gas in the centre of the burner is closed at the top to prevent solder or
other material from choking and holes are made in the side to admit gas.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
-
In a Bunsen burner, the combination of a bye-pass and a valve in the main
pipe provided with a spring or equivalent, by which the valve is automatically
closed when the burner is not in use, substantially as described and illustrated
on the accompanying sheet of drawings.
