provements in Gas Generators suitable for Producing Acetylene
I, ERNEST GEARING, of Penshurst, Clarence Drive, Harrogate, in the County
of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to improvements in gas generators suitable for
producing acetylene by the use of a suitable metallic carbide such as carbide of
calcium and water, the supply of the latter being controlled in an automatic manner
The main or body part of the generator is constructed of steel plates vetted
together with an opening about midway of its height for the introduction of carbide,
which opening is provided with a door that can be hermetically closed with
another opening provided with a similar door at or near the bottom for the purpose
of clearing out lime and bye-products; and with an outlet at the side near the top
for gas generated.
:
The apparatus for supplying and in an automatic manner controlling the supply
of water is arranged at the upper part of the generator body and is so constructed
that when gas is being generated more rapidly than it is being drawn off through
the outlet the consequent increase of pressure within the generator will operate the
valve controlling mechanism so as to shut off or partly shut off the water supply
until by the withdrawal of gas the pressure in the generator falls whereupon the
water supply will be automatically more or less opened. This may be effected in
various ways; according to one aangement a lever having its fulcrum in a suit-
able standard or upright has connected to one of its arms the spindle of a controlling
valve and to the other arm a collapsible vessel or a diaphragm exposed to the
pressure of the gas within the generator the respective arms of the lever being
also furnished with weights by adjusting which the apparatus can be set to cut off
the supply of water on the gas within the generator attaining such pressure as may
be pre-determined. With this arrangement, when gas is being gonerated more
rapidly than it is being drawn off, and the pieseme within the generator conse-
quently increases such pressure acting against the top of the collapsible vessel, or
upon the diaphragm (as the case may be) will lift one end of the lever thereby
depressing the other end to which the water valve spindle is connected and thus
will gradually cut off the supply of water and arrest the generation of gas.
As gas is drawn off and the pressure consequently reduced a reverso action of
the lever will occur whereby the valve will be opened the supply of water will be
renewed and generation of gas will again take place.

page_text: Improvements in Gas Generators suitable for Producing Acetylene.
I, ERNEST GEARING, of Penshurst, Clarence Drive, Harrogate, in the County
of York, Engineer, 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.―
My invention has reference to improvements in gas generators suitable for
producing acetylene by the use of a suitable metallic carbide such as carbide of
calcium and water, the supply of water being controlled in an automatic manner.
Refering to the accompanying illustrative drawing which shows, partly in
elevation and partly in vertical section, a gas generating apparatus according to
my invention, a is the main o body part of the generator, constructed of steel
plates rivetted together, with an opening about midway of its height for the intro-
duction of carbide, which opening is provided with a doo b that can be
hermetically closed, with another opening provided with a similar door cat or
near the bottom for the purpose of clearing out lime and by-products; and with
an outlet at the side near the top for gas generated.
The apparatus for supplying and in an automatic manner controlling the supply
of water is arranged at the upper part of the generator body a and is so con-
structed that when gas is being generated more rapidly than it is being drawn off
through the outlet d the consequent increase of pressure within the generator will
operate the valve controlling mechanism so as to shut off or partly shut off the
water supply, until, by the withdrawal of gas, the pressure in the generator a
falls, whereupon the water supply will be automatically more or less opened. In
the arrangement illustrated e is a lever having its fulcrum el in a suitable standard
or upright, and has connected to one of its aims the spindle g of a controlling
valve and to the other arm a collapsible vessel (or a diaphragm) exposed to
the pressure of the gas within the generator a, the respective arms of the lever
being also furnished with weights kaud by adjusting which the apparatus can
be set to cut off the supply of water on the gas within the generatoi a attaining
such pressure as may be pre-determined With this aangement, when gas 18
being generated more rapidly than it is being drawn off, and the pressure within
the generator consequently increases such pressure acting against the under surface
of the top of the collapsible vesse! (or upou the diaphragm as the case may be)
will lift the corresponding end of the lever e thereby depressing the other end to
which the water valve spindle g is connected and thus will gradually cut off the
supply of water and arrest the generation of gas, the valve closing against a
suitable seat.
As gas is drawn off and the pressure consequently reduced a reverse action of
the lever e will occur whereby the valve will be opened, the supply of water
will be renewed and generation of gas will again take place.
The construction of the apparatus may be modified in various ways without
depaiture from the essential characteristics of my invention and care being taken
in all cases that the valve is such as when open not to admit water in excess to
the generator a, The drawing represents the generator of cucular form in plan
which, for strength is preferable; in lieu of the collapsible vessel as shown a
diaphragm of any suitable construction such as a disc of leather or vulcanised
india rubber secured around its periphery to the surrounding casing and provided
with a central metal plate or plates for attachment of the connecting rod m,
might be substituted and in lieu of a water valve of the construction indicated
at a valve of any other suitable constinction capable of being worked directly
or indirectly from the lever e might be substituted as for example a cock with
plug adapted to be partially rotated by means of a lever arm fast at one end on

page_text: the plug spindle and having jointed to its other end a rod connected by a suitable
Joint to the lever e.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A gas generator of the kind referred to, wherein the supply of water 18
controlled in an automatic manner the construction and arrangement being such
that when gas is being generated more rapidly than it is being drawn off the con-
sequent increase of pressure within the generator will operate the valve controlling
mechanism so as to shut off or partly shut off the water supply, until by the
withdrawal of gas, the pressure in the generator falls, whereupon the water supply
will be automatically more or less opened.
2. My improved apparatus as described with reference to the diawings for the
purpose specihed.
