PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Generating Acetylene Gas.
I, JOHN HENRY EXLEY, of Byram Street, Huddersfield, in the County of
York, Merchant, do hereby declare the nature of this invention to be as
follows:-
-
This invention particularly relates to that type of apparatus for generating
acetylene gas in which the water is automatically fed to the generator from the
holder, and also to that type of apparatus in which an automatic stop valve or
regulator is fitted in the passage from the generator to the holder.
To automatically close the valve between the generator and the holder as soon
as the desired amount of gas is contained in the holder I employ a float in the
holder connected to said valve and arranged in such a manner that when the water
in the holder falls to a certain point the said float falling with it closes said valve
and keeps it closed until the water again rising in the holder lifts the float and
opens the valve. Two or more generators may be connected by the same valve to
the holder.
For the purpose of reducing the bulk of water circulating between the generators
and the holder and to reduce the surface exposed to evaporation when the water is
lowered out of action upon the carbide and to reduce the quantity of water wasted
when the generators are emptied I form a neck or reduce the diameter of the
generators immediately below the bottom of the carbide in the generators but
enlarge it again below to form a receptacle for solid matter.
Dated this 29th day of October 1895.

Improvements in Apparatus for Generating Acetylene Gas.
I, JOHN HENRY EXLEY, of Byram Street, Huddersfield, in the County of
York, 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 :-
This invention relates to improvements in the apparatus for generating acetylene
gas for which I have obtained Letters Patent No. 12,344 dated the 26th June
1895, and other similar apparatus.
To more rapidly expel the water from the generator when the consumption of
gas is suspended an automatic valve is introduced in the gas passage between the
generator and the holder adapted to close when a certain quantity of gas is
contained in the holder so that any further generation of gas at once expels the
water from the generator and arrests generation.
Figure 1, represents a vertical section of such parts of the apparatus shown in
the above cited specification as are necessary to illustrate the application of my
improvements thereto.
Figure 2, represents a plan of the same.

page_text: The gas passages G, G connecting the generators F and F 2 with the holder A
are preferably carried over the top of the cistern B and are connected to the gas
pipe G 3 (passing through the diaphragm C into the holder) by the valve box G 4.
This valve box has a valve seat G 5 and is fitted with a valve G 6 connected by
the rod G7 to the float G 8 in the holder.
As soon as sufficient gas has accumulated in A to lower the water therein to such
a point that the valve G 6 is brought down onto its seat the further passage of gas
by either of the pipes G is prevented consequently any gas afterwards generated
accumulates in the generator displicing the water therein and prevents water being
again admitted until the valve G6 is again raised from its seat.
For the purpose of reducing the bulk of water circulating between the generators
and the holder and to reduce the surface exposed to evaporation when the water is
lowered out of action upon the carbide and to reduce the quantity of water wasted
when the generators are emptied I form a neck or reduce the diameter of the
generators at F 3 immediately below the bottom of the carbide in the generators
but I enlarge it again below to form a receptacle for solid matter.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination with an acetylene gas apparatus of the type specified, of a
valve located in the gas passage from the generator to the holder and adapted to
close automatically when a definite quantity of gas is stored in the holder and
remain closed until such quantity of gas is more or less consumed, substantially as
herein shown and described and for the purpose specified.
2. The combination with an acetylene gas apparatus of the type specified, of the
float. G8 and valve G 6 arranged and operated substantially as herein shown and
described.
Dated this 28th day of July 1896.
