Improvements in Apparatus for Generating Gas by the Addition
of a Solid to a Liquid.
We, GEORGE WILLIAM GASKELL and RICHARD FREDERICK REEVE, both of 186,
Park Road, in the City of Liverpool, Photographic Sundriesmen, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object a system whereby the generating chamber in
an acetylene, carbonic acid, or sulphuretted hydrogen, generating apparatus can
be re-filled automatically with carbide, sulphide or carbonate whenever the gas
gets low, and can be re-charged at leisure with the escape of gas beyond that
actually in the charge box at the time, and the invention consists essentially in
having a charge box in the gasometer bell capable of being supplied from the
exterior and so arranged that whenever the gasometer bell falls to a given point
this box shall discharge its contents into the generator and as the gasometer
bell rises again shall be automatically closed air-tight. The lid can then be taken
off and the box charged at leisure. The lid is then applied and the charge box
is now ready to again supply the generating chamber as it descends. In our
experimental device we have balanced the bottom of the supply box on a lever
hinged to the side of the box. The other end of this lever has a weight suspended
from it by a chain or a bar or the like in such manner that when the gasometer
bell approaches its lowest position this bar or weight rests on the bottom and
allows the trap door floor of the charge box to open and shoot its materials on to
the diaphragm or cage of the generating chamber. We form the generating
chamber preferably by placing a removable horizontal diaphragm in the gasometer
bell. This removable diaphragm consists of a disc having two segments opposite
each other cut out and two segments a little smaller than these are fixed to the
side of the gasometer bell. The consequence is that in one position the bottom
will rest on the two side segments while in the position at right angles thereto
it will be clear of them and can be emptied into the bottom or lifted up with the
material on it. Other forms of removable bottom can however be used. Another
improvement in our apparatus consists in placing an exit box on the gasometer.
This exit box has two chambers one filled with sponge, the other with asbestos.
It can however have any number of chambers through which the gas has to
pass and these chambers can be filled with any material suitable for purifying
and cooling the gas. By this means if the gas be mixed with air after leaving the
gasometer all chance of explosion through residual heat is avoided.

We, GEORGE WILLIAM GASKELL and RICHARD FREDERICK REEVE, both of 186,
Park Road, in the City of Liverpool, Photographic Sundriesmen, 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 has for its object a system whereby the generating chamber in

actually in the charge box at the time, and the invention consists essentially in
having a charge box in the gasometer bell capable of being supplied from the
exterior and so arranged that whenever the gasometer bell falls to a given point
this box shall discharge its contents into the generator and as 'the gasometer
tell rises again shall be automatically closed air-tight. The lid can then be 'taken
off and the box charged at leisure. The lid is then applied and the charge box"
is now ready to again supply the generating chamber as it descends.

In our experimental device we have balanced the bottom A of the supply box B
on a lever Chinged to the side of the box at c. The other end of this lever has :
a weight D suspended from it by a chain or a bar or the like E in such a
manner that when the gasometer bell F approaches its lowest position this bar
or weight rests on the bottom G of the outer cylinder H and allows the trap
door floor A of the charge box to open and shoot its materials on to the diaphragm
or cage I of the generating chamber J. We form the generating chamber prefer-
ably by placing a removable horizontal diaphragm in the gasometer bell. This
removable diaphragm I consists of a disc, Figure 3, having two segments K
opposite each other cut out and two segments L a little smaller than these are
fixed to the side of the gasometer bell.
the bottom will rest on the two side segments, while in the position at right
The consequence is that in one position
angles thereto it will be clear of them and can be emptied into the bottom or
lifted up with the material on it. Other forms of removable bottom can however
be used. Another improvement in our apparatus consists in placing an exit box
or chamber inside the gasometer. This exit box has two chambers M and N,
one filled with sponge, the other with asbestos. It can however have any
number of chambers through which the gas has to pass and these chambers can
be filled with any material suitable for purifying and cooling the gas. The two com
partments of the box are separated by a perforated metal disc O, the bottom P is 4
also perforated. By this means if the gas be mixed with air after leaving the
gasometer all chance of explosion through residual heat is avoided. "Q is the
outlet for gas and R a safety valve to prevent undue pressure of the gas.

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 '4
we claim is:-
1. The improvements in annaratus for monerating

page_text: solid to a liquid, consisting of a charge or supply box placed inside the gasometer
bell, which box is capable of being supplied from the exterior and is so arranged
that whenever the gasometer bell falls to a given point it shall discharge its
contents into the generator and as the gasometer ball rises again shall be auto-
matically closed gas-tight.
2. In a gas generator such as described, the means whereby the contents of
the charge or supply box is discharged into the generator, which consists in
providing such box with a balanced door or bottom held normally closed by a
weight suspended from a lever fixed to the door, but when the gasometer falls to
a given point such weight striking the bottom of the outer cylinder allows of the
door of the charge box being opened by the weight of the charge contained
therein.
3. In a gas generator such as described, an exit box arranged inside the gaso-
meter and having two or more chambers constructed substantially as and for the
purposes herein set forth.
4. The improvements in gas generators taken as a whole substantially as herein
described and shown on the accompanying drawing.
