PROVISIONAL SPECIFICATION.
Improvements in and connected with Acetylene Gas Generators.
We, WILLIAM ELLEN, of Knighton, Radnorshire, Acetylene Lighting Engineer,
and WILLIAM IRELAND DAVIES, of Bucknell, in the County of Salop, Timber
Merchant, do hereby declare the nature of this invention to be as follows:-
Our invention has for its object improvements in and connected with acetylene
gas generators by which we prevent any possibility of a back flow or escape of gas
through the carbide chamber when opened thereby obviating any risk of explo-
sion from this cause, and this we carry out in a simple cheap and effective manner.
In carrying our invention into effect the gasometer end of the connection from..
the carbide chamber is provided with a flexible pipe having attached thereto at
or near its end a hollow metal or other suitable float so weighted and arranged
that the end of the pipe remains just sufficiently under water to allow of a free
passage into the gasometer and at the same time prevents a return of the gas
through the said pipe. This arrangement also ensures the passage of the gas
through the water into the gasometer thus washing it free of some of its impurities.
The flexible pipe is made sufficiently long so as to allow the float to accomodate
itself to the varying levels of the water in the gasometer and the float may be
made adjustable upon the pipe for the purpose of regulating the amount of dip
of pipe in the water.
By these means the possibility of a back flow of gas through the carbide chamber
when open is prevented in a cheap yet effective manner.

Improvements in and connected with Acetylene Gas Ġenerators.
We, WILLIAM ELLEN, of Knighton, Radnorshire, Acetylene Lighting Engineer;
and WILLIAM IRELAND DAVIES, of Bucknell, in the County of Salop, Timber
Merchant, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
Our invention has for its object improvements in and connected with acetylene
gas generators by which we prevent any possibility of a back flow or escape of gas
Through the carbide chamber when opened thereby obviating any risk of explo-
sion from this cause, and this we carry out in a simple cheap and effective manner.
By our invention the gasometer end of the connection from the carbide cham-
071

page_text: ber is provided with a flexible pipe having attached thereto at or near its end a
hollow metal or other suitable float so weighted and arranged that the end of the
pipe remains just sufficiently under water to allow of a free passage into the
gasometer and at the same time prevents a return of the gas through the said pipe.
This arrangement also ensures the passage of the gas through the water into
the gasometer thus washing it free of some of its impurities.
The flexible pipe is made sufficiently long so as to allow the float to accomodate
itself to the varying levels of the water in the gasometer and the float may be
made adjustable upon the pipe for the purpose of regulating the amount of pipe
in the water. By these means the possibility of a back flow of gas through the
carbide chamber when open is prevented in a cheap yet effective manner.
In order that our invention may be clearly understood and more easily carried
into practise we have appended hereunto a sheet of drawings upon which we
have fully illustrated the nature of our said improvement.
Figure 1 is a vertical section through a gasholder adapted for receiving
acetylene gas from any suitable generator.
In carrying our invention into effect the end e¹ of the connection E from the
generator is provided with the flexible pipe which is preferably provided with
an internal coil of galvanized wire for the purpose of preventing the collapse of
the tube at the bend. At or near the end of this flexible pipe the hollow metal or
other similar float A is attached and is so weighted and arranged whatever the
level of the water may be within reasonable limits the end at remains sufficiently
below the surface to allow of an easy and free passage into the holder B and at
the same time washing the gas of some of its impurities and preventing any
possibility of the return of the gas in the holder through the said pipe to the
generator. The flexible pipe a¹ is made of sufficient length to allow the float A to
accomodate itself to the varying levels such as F, G, H, of the water K in the gaso-
meter as illustrated by dotted lines and while the float is preferably made
adjustable upon the flexible pipe this being effected in a simple manner by the
socket which is made to fit the rubber pipe sumciently tight to retain the float
in the required position but in such manner that it can at the sanice time be slid
up or down the pipe when so required or the float A may be attached to the pipe
by any suitable clip by which means the amount of pipe projecting into the water
and thereby the distance of the mouth from the surface may be regulated as
desired. The float may be varied in shape or material as also the flexible pipe
while the connection at el may be made horizontal instead of vertical if so desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1st In holders for acetylene gas providing the delivery pipe from generator
with a flexible end supported by a float so as to cause the gas to pass through the
water at varying levels and at the same time prevent any backflow of gas from
the holder to the generator substantially as set forth.
2nd In holder for acetylene gas having a flexible and floating end to the
delivery pipe mounting such float upon the flexible pipe in such manner as to be
capable of adjustment in position substantially as set forth.
Dated this 2nd day of February 1900.
