PROVISIONAL SPECIFICATION.
Improvements in or connected with Acetylene Gas Generators.
We, WILLIAM WALTER REGINALD WARN, of 50, High Street, Poole, Dorset, and
LEWIS FRANK KING, of 209 High Street, Poole, Dorset, Gentlemen, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in or connected with acetylene gas
generators, the object being a special arrangement or construction of same whereby
the requisite amount of gas may be generated without waste, our improved apparatus
being suitable for lighting and heating or for gas engines, motors or for all other
purposes to which such an apparatus can be applied.
In carrying our invention into practical effect our improved apparatus consists
of a double tank or chamber so arranged as to leave a space between same designed to
contain water under pressure, which is pumped into same by means of a suitable pump
arranged upon the outside of the tank or chamber. Within the inner tank or
chamber we arrange any suitable number of cells each designed to contain calcium
carbide and calcium (or stone lime) the latter being inserted to prevent smoking,
while around and over the cells we arrange a suitable pipe connected with the
outer chamber or tank containing the water under pressure, so that water may be
adınitted to one, two or all of the cells as required, according to the amount of gas
to be generated, by opening the valve or cock corresponding with the cell required,
the water in the outer tank or chamber being at such a pressure as to allow of its
entering the said cells against the pressure of the gas.
We may provide any suitable stop-cocks, pressure or water gauges and safety valves
or the like, as may be deemed necessary, and our apparatus may be made in any size
and with any number of cells according to requirements.

Improvements in or connected with Acetylene Gas Generators.
We, WILLIAM WALTER REGINALD WARN, of 50 High Street. Poole, Dorset, and
LEWIS FRANK KING of 209, High Street, Poole, Dorset, Gentlemen, 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 or connected with acetylene gas
generators, the object being a special arrangement or construction of same whereby
any required amount of gas may be generated without waste, our improved apparatus
being suitable for lighting and heating, or for use in connection with gas engines,
motors, and for all other purposes for which it is suitable.

page_text: In carrying our invention into practical effect, our improved apparatus consists of
a double tank or chamber arranged so as to leave a space between the two parts
within which is contained water under pressure, which is either forced into same
by means of a suitable force pump or the pressure may be applied by means of
the gas generated in the inner chamber, as hereinafter more fully described.
Within the inner tank or chamber we arrange any convenient number of cells,
each designed to contain a sufficient quantity of calcium carbide and stone lime,
the latter being inserted to prevent smoking, while around and over the cells we
arrange a suitable supply, pipe connected with the outer chamber containing the
water under pressure, so that water may be admitted to one, two, or more cells as
required according to the amount of gas to be generated.
In order that our invention may be more fully understood, we will now proceed
to describe same with reference to the accompanying drawings, in which
Fig. 1 is a sectional elevation of our improved apparatus.
Fig. 2 being a cross section on liner of Fig. 1.
Fig. 8 is a top view or plan of the apparatus."
Our improved apparatus consists of an outer chamber a and an inner chamber a
arranged in such a manner as to leave a space between them, designed to contain
water under pressure. Within the chamber a' is arranged a circular table b preferably
upon a central support such as e, and arranged so as to be free to revolve, while
upon the said table is mounted the required number of cells d, each designed to
contain calcium carbide and stone lime.
P
Above the cells l wo arrange a circular pipe (Figs. 1 and 2) fitted with stop-
cooks s, one over each cell, and designed to be opened or closed by turning the
connecting rods by thuir caps or discs g. The pipe p passes through the inner
chamber a where it is connected with a vertical pipe p' for supplying the water
contained within the space between the aforesaid two chambers, the said pipe being
furnished with a main stop-cock to he operated by the rod r. is a pressure
gauge fitted over the top of the inner chamber for indicating the pressure of the
gas and is a suitable water gauge, while over the aforesaid inner chamber is
arranged the main outlet gas pipe o. We preferably farther arrange above the cells
a perforated metal plate designed to contain lime or other suitable moisture
collecting material, in order that the gas may be well dried before being used, while k
indicates a suitable wash-out pipe. Within the side of the apparatus we provide a
suitable opening or manhole m (Fig. 2) having a screw down cap or cover m', the
manhole or opening being arranged on a line with the cells so that ready access may
be had to same for recharging when required, each cell being brought opposite the
opening in turn by revolving the aforesaid table b
The operation of our improved apparatas is as follows:
The cells d having been charged with calcium carbide and stone lime, water is
passed into the space between the two chambers a and a', through a screw plug g.
One of the stop-cocks s is then opened and the water passes into a cell, generating gas
which fills the inner chamber a to a greater pressure than the weight of water. The
gas then passes back through the water pipe and sets up a pressure in the outer
chamber until an equilibrium of pressure in the two chambers is restored, so that
as many lights may be turned on as required, the pressure of the gas keeping the
water from entering the cells when the supply of gas is greater than the demand,
and the gas supply pipe o may be furnished with any suitable stop-cocks and
regulators as required.
We way in some cases employ a suitable force pump having water and air
inlets, for passing the water under pressure into the space between the aforesaid two
chambers, but we prefer to adopt the method hereinbefore described.
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. The new or improved apparatus for generating acetylene gas comprising an

page_text: inner and outer chamber a, a', having a space between them designed to contain
water under pressure, in combination with a revolving table such as having any
required number of cells d placed thereon, supply pipes p, p', having stop-cocks s, s,
a perforated grid or plate h, designed to contain drying material and suitable gauges
as required, the whole combined, arranged and operating, substantially as herein
described and shown and for the purposes specified.
2. In an apparatus for generating acetylene gas such as above claimed, the arrange-
ment of same whereby the pressure within the inner and outer chamb rs is equalised
or kept at an equilibrium, substantially as herein described and shown with reference
to the accompanying drawings.
3. The new or improved apparatus for generating acetylene gas, arranged
constructed and operating, substantially as herein described and shown, and for the
purposes specified.
