PROVISIONAL SPECIFICATION.
Apparatus for Automatically Generating Gas.
GEORGE WEBB 27 Goda Street Princess Road Kennington Mechanic, JOSEPH
WILLIAM KELLY 70 Finsbury Pavement E.C. Gentleman do hereby declare the
nature of this invention to be as follows:-
We cause a supply of water to act on a substance called calcium carbide
automatically by the rise and fall of a body of water acting in what is known as a
centre partation gas holder.
The action is as follows When the body of water has been forced into the top
part of the gas holder the carbide is not in contact with the water but on the
supply of gas which is in the bottom half of holder being used the water descends
and comes in contact with the carbide and therefore generates a supply of gas
which drives the water back again into the top part of the gas holder which will
leave the carbide dry and ready to repeat the action again.

Apparatus for Automatically Generating Gas.
I GEORGE WEBB of 89 Wharton Road, Shepherd's Bush in the County of
Middlesex late of 27 Goda Street, Princess Road, Kennington, Mechanic and
JOSEPH WILLIAM KELLY of 70 Finsbury Pavement in the City of London,
Gentleman 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 relates to apparatus for automatically generating gas by means of
a fall or head of water contained in a centre partition gas holder acting upon
calcium carbide when the gas falls below a certain pressure.
The gas holder is provided with gas and water connections leading to a chamber
containing the calcium carbide holder which is fitted with a central tube open at both
ends, and through the upper part of the gas holder there passes a gas outlet pipe
leading from the lower or gas chamber. As the pressure of gas decreases by use
the water descends by a central tube into the lower part of the holder into which
it rises until it reaches the level of the top of the tube in the calcium carbide.
The water then overflows from the said tube on to the calcium carbide thus
generating gas which passes into the gas holder and from thence to the gas outlet
pipe, the pressure of the gas at the same time forcing down the water in the lower
part of the holder and raising it into the upper part, thereby creating a head or
fall sufficient for developing a fresh supply of gas when the pressure of the latter
becomes reduced.
In the accompanying sheet of drawings illustrating our invention Figure 1
is a vertical section of our improved apparatus and Figure 2 is a plan of the
same.

page_text: a is a gas holder divided into an upper and a lower chamber by the partition a¹
fitted with the central tube a 2 and a gas outlet pipe a 3. b is the chamber con-
taining the calcium carbide holder e provided with the central tube c' open at
both ends.
This chamber is fitted with a cover for the. purpose of filling the holder c
with the calcium carbide c2. is the gas connection between the gas holder and
the chamber b, and e is the water connection.
The operation is as follows;-The cocks d¹ and e¹ of the connections and e
being turned on the water in the upper part of the gas holler passes down, by its
own gravity the tube a 2 and through e into the chambers 6 from whence it
passes up the tube c' and overflows on to the calcium carbide c 2.
This causes the generation of gas which passes through the connection d into the
gas holder where it acts upon the surface of the water therein so as to force it up
the tube a 2 into the upper part of the holder a. The gas then passes away by the
pipe a 3 and as its pressure decreases the water in the upper part of the holder a
again descends until it overflows the tube c' to create fresh gas as before described
this action being automatically repeated as long as there is a sufficient quantity of
calcium carbide to create fresh gas.
The chamber may be rectangular instead of round and we may use two or
more tubes c¹ instead of one as shown.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. In apparatus for automatically generating gas the use of a gas holder con-
taining a head or body of water a portion of which is brought into contact with a
chemical such as calcium carbide upon the pressure of the gas decreasing substantially
as described and herein set forth.
2. In apparatus for automatically generating gas the combination with the gas
holder a divided into upper and lower chambers by a partition a' and fitted with
a central tube a 2 and gas outlet a 3, of a chamber 6 provided with a cover b¹ and
carrying a holder c containing calcium carbide and fitted with a central tube c¹ and
gas and water connections d, e fitted with cocks d' e substantially as described
and for the purposes specified.
3. The improved apparatus for automatically generating gas substantially as
described and shown in the drawings.
