Improvements in Apparatus for the Manufacture of Acetylene Gas.
JOHN VEDA ROBINSON, Photographer, The Green, Malahide, Co. Dublin, do
hereby declare the nature of this invention to be as follows:-
I construct the apparatus of three tubes, of any suitable shape, and of any
suitable material, preference being given to zine, each of these three tubes will
fit loosely into one another, the largest one I call A the next smaller B the smallest
C--each of these three tubes is closed at one end, except that in B, there is a
small aperture or pipe to be used for the conveyance of the gas. One or more
small holes, are drilled in the sides of C tube, to be used for the purpose of
admitting water to the carbide. The carbide of calcium is placed in C tube the
closed end of C being downward and B tube is placed over C tube, the closed
end of B being uppermost a small catch or similar device capable of acting
like a bayonet catch, holds, C tube inside B tube. Tube B carrying tube C, and
the carbide charge is now placed in tube A, the open end of B being down-
wards, and B tube is held in A tube by a catch or similar contrivance, as in the
case of C and B tubes. The tube A may be partly full of water at the time
the B tube carrying the C tube is inserted, or water may be afterward added. The
action to liberate gas will be as follows the carbide being in tube C, and the
water in A tube if the pipe on B be opened the air in B will escape, and the
water in A. rise up in B fube until it reaches the hole drilled in ('tube, by this
hole the water is admitted to the C tube and coming into contact with the carbide
liberates the gas, which if not let out by the pipe on B will accumulate in B, and
force back the water from entering into C tube, if the gas is allowed to escape
from B tube water will again enter by the hole or holes in C tube and again
liberate gas. It will be evident that the construction of such an apparatus is
very simple that the charge of carbide can easily be put in tube C, and that
same tube can be easily cleaned from the spent carbide that the apparatus can be
quickly and easily taken to pieces and put together again, and that the pressure
can never exceed that of a column of water equal in height to the height of
tube A.

page_text: performed, to be particularly described and ascertained in and by the following
statement:-
I construct this apparatus of three vessels each with one end open, they may
be cylindrical or other shape so that one will go within the other the largest one
is to contain the water for generating the acetylene from the carbide of calcium,
and it forms the body of the apparatus the vessel next in size is the gas, container,
it has a tube or tap in its closed end for conveyance and use of the gas, it is
placed with its open end downward into the water in the largest vessel, the
smallest vessel is the carbide container it is used with its open end upwards
attached or held by any suitable mechanical arrangement, inside the gas container
this (the smallest vessel) has one or more holes in its sides by which the water
in the largest vessel can get access to the carbide. The action of this generator
is as follows, the charge of carbide is placed in the smallest vessel which vessel
is placed and held by any suitable catch inside the second size vessel, it (the
gas container and carbide container combined) is now placed open end downward
into the largest vessel and held there by a catch or similar arrangement. When
the three vessels have been so combined, and there being water in the largest
vessel, the tap of the gas container is opened the air which was in the container
will escape, the water from the largest vessel will rise up inside the gas container
and round the carbide container until it reaches the height of the lowest hole in
the carbide container when it will enter into the carbide container and coming
into contact with the carbide liberate acetylene gas, if this hole is of such a size
as to admit sufficient water to yield the quantity of gas required the water will
remain at the same height round the carbide container, but if the yield of gas
is not sufficient the water will rise up to the next hole through which water is
admitted or if the quantity of water through the first hole was such as to liberate
more gas than required the pressure will accumulate in the gas container and
push back or downwards the water which surrounds the carbide container until
the level of the water is lower than the lowest hole or to the bottom of the gas
container when the gas escapes through the water in the largest vessel.
The rate of liberation of gas is influenced by the height of the column of
water in the outer vessel.
For the more particularly describing my apparatus--the manner in which
same is constructed, and combined to form the generator, I herewith append
drawings of same.
Fig. 1, is the carbide container. , are the holes for admission of water.
Fig. 2, is the gas container.
Fig. 3, is the largest vessel or water container.
Fig. 4, is the combined apparatus, consisting of Fig. 1, Fig. 2, & Fig. 3, ready
for the production of gas.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The construction of an acetylene generator substantially as described.
2. The construction and use of an acetylene generator where the rate of libera-
tion of the gas is controlled substantially as described.
