Improvements in Devices for Controlling the Supply of Feed Water
to Acetylene Gas Generators.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a device, the object of which is to so reverse, auto-
matically, the feed of water to a carbide cell in acetylene generators as soon
as such cell is exhausted-that the feed water is conveyed toward a fresh carbide
cell and the latter thus thrown into action.
The supply of water to the carbide cells, is regulated by a conical plug, which
is carefully ground into its casing also of an internally conical shape. The plug,
through the medium of a screw nut is firmly connected with a ratchet wheel and
is provided with six radial ports which are connected with each other in pairs.
In the casing are likewise formed three ports arranged at corresponding distances
apart, in which terminate pipes, of which latter one effects the feed of water
to each carbide cell and the other two the discharge of water from each
carbide cell. The water feed is regulated by a toothed wheel which is
connected with the cut off valve in the feed pipe and is acted upon by a rack bar
fixed to the bell or slide-cover of the gas holder. The lower end of the rack bar
is provided with a thrust-pawl or lever, engaging with the ratchet wheel and
working under the action of a spring.
The operation of the device described, is simply as follows:
If the position in which communication is established between the feed pipes
and one of the discharge pipes be taken as the initial position, then-during the
period of low level of the bell or slide cover of the gas holder-water will flow out
of the feed pipe through the said discharge pipe to the carbide cell connected or
communicating with said discharge pipe, until the bell or slide cover rises and,
in so doing, closes the cut off valve in the feed pipe, connected with the toothed
wheel, this operation being due to the fact, that the rack bar moves in conjunction
with the bell or slide cover. If the said bell or slide cover descends to a small extent,
the cut off valve is opened to a corresponding extent and feed water is again
enabled to flow through the aforesaid discharge pipe to the corresponding carbide
cell, connected therewith. This operation continues, until the carbide in the
said cell has been exhausted. As the generation of gas ceases, at this moment
the bell or slide cover of the gas holder slowly descends and now so reverses the
plug through the medium of the thrust pawl or lever and of the ratchet wheel,
that the water feed pipe is thrown in communication with the other exhaust

page_text: pipe leading to a second carbide cell. The operations above described is then
repeated until the second cell is exhausted, whereupon the first cell which has
been newly charged in the meantime is again automatically connected.

Improvements in Devices for Controlling the Supply of Feed Water
to Acetylene Gas Generators.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents
45, Southampton Buildings, in the County of Middlesex, 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 a device, the object of which is to automatically cut
off the feed of water to a carbide cell in acetylene generators as soon as such
cell is exhausted-and to convey the said feed water towards a fresh carbide cell
and thus throw the latter into action.
A constructional form of this invention is represented in the accompanying
drawing, in which
Figure 1 is a general view of the device complete.
Figure 2 is a sectional view of the plug cock on an enlarged scale.
Figure 3 is an enlarged view of the ratchet wheel and its operating lever, and
Figure 4 an elevation of the plug cock.
The supply of water to the carbide cells, not shown in the accompanying
drawing, is regulated by a conical plug B Figure 2, which is carefully ground
into its casing A also of an internally conical shape. The plug B, through the
medium of a screw nut E Figure 4, is firmly connected with a ratchet wheel D
and is provided with six radial ports C, each two of which are connected with
cach other, see Figure 2. In the casing A is likewise formed three ports arranged
at corresponding distances apart, in which terminate the pipes G, H and J, of
which latter, G effects the feed of water to each carbide cell and the other
two and the charging of water to each carbide cell respectively. The water
feed is regulated by a toothed wheel M (Figure 1), which is connected with the
cut off valve F in the feed pipe G and is acted upon by a rack bar K, fixed to
the bell or slide-cover of the gas holder. The lower end of the rack bar is
provided with a thrust pawl or lever L, engaging with the ratchet wheel
Figures 1 and 3 and working under the action of a spring.
The operation of the device, described, is as follows:
If the position shown in Figure 2, where communication is established between
the pipes G and J be taken as the initial position, then-during the period of
low level of the bell or slide cover of the gas holder-water will flow out of the
feed pipe G through the said charging pipe J to the carbide cell connected or
communicating with said pipe J, until the hell or slide cover rises and, in so doing
closes the cut off valve in the feed pipe, F, connected with the toothed wheel M
this operation being due to the fact, that the rack bar K moyes in conjunction
with the bell or slide cover. If the said bell or slide cover descends to a small extent,
the cut off valve F is opened to a corresponding extent and feed water is again
enabled to flow through the aforesaid pipe J to the corresponding carbide cell,
connected therewith. This operation continues, until the carbide in the said
cell has been exhausted. As the generation of gas ceases the bell or slide cover

page_text: of the gas holder slowly descends and in doing so turns the plug B through the
medium of the thrust pawl or lever Land of the ratchet wheel 1, that the water
feed pipe G is thrown in communication with the other charging pipe H, leading
to a second carbide cell. The operation above described is then repeated, until
the second cell is exhausted, whereupon the first cell which has been newly
charged with carbide in the meantime, is again automatically connected with
the water feed pipe G.
Having now particularly described and ascertained the nature of this invention
and; in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is:-
1. An automatic controlling device for the supply of water to acetylene gas
generators, characterised by a cock plug (1) actuated by the gasometer dome
by means of operating mechanism (L, D), the passages in such plug being so
arranged that upon the sinking of the dome consequent upon the exhaustion of
a carbide cell, the water supply to this cell is automatically cut off and diverted
to another cell.
2. A constructional form of the water supply controlling device described in
Claim 1, in which the operating wheel (D) connected with the rotatable cock
plug (B) is actuated by means of a spring operating-member (L) which is
arranged upon the lower end of a rack (K) connected with the gasometer dome
and acting upon the cut-off valve (F) of the water supply pipe (G).
