Improvements in Acetylene Gas Generators.
We, THOMAS LYONS and JAMES LYONS, of 21, Cardwell Place, Blackburn, in the
County of Lancaster, Tin Plate Workers, and JOHN PEARSON, of 14, Bombay
Street, Blackburn aforesaid, Sheet Metal Stamper, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in acetylene gas generators, the object
being to prevent the escape of gas when the apparatus is being charged with cal-
cium carbide, and thereby to minimize the danger, and the invention consists of
simple apparatus whereby the caps or covers of the generator are securely fixed
in position and made gas tight before the vessel containing the calcium carbide
is lowered or moved into contact with the water which causes the gas to generate.
According to this invention, in the vessel or chamber containing water is a hole
for the reception of the vessel containing the calcium carbide, and this hole is
flanged and has a cap or cover which is tightly fixed in position by nuts or screws.
Through the centre of the cap or cover is a right and left handed threaded spindle
which carries a vessel, the lower end of the spindle passing through the bottom of
the vessel. Inside the vessel is a perforated vessel containing the calcium carbide.
The outer vessel and the cap or cover are placed in position, the vessel dipping
into the water in the well but allowing no water to get inside to the calcium car-
bide. The cap or cover is now secured in position and the whole made gas-tight,
then by turning the chased spindle, the outer vessel is lowered, and the spindle
passing through the bottom opens the hole and allows water to flow inside the
vessel and to the perforated one containing the calcium carbide. The apparatus
can be made in duplicate so that as the contents of one are being used, the other can
be charged.

page_text: 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 acetylene gas generators, the object
being to so construct the apparatus as to prevent the escape of gas when the
apparatus is being charged with calcium carbide, and thereby to minimize the
danger, and the invention consists of simple apparatus whereby the caps or covers
of the generator are securely fixed in position and made gas tight before the vessel
containing the calcium carbide is lowered or moved into contact with the water
which causes the gas to generate.
Such being the nature and object of our said invention, the following is a com-
plete description of same, reference being had to the accompanying drawings, in
which:
Fig. 1 is a sectional side elevation of the improved acetylene gas generator.
Fig. 2 is an end elevation of the improved apparatus.
According to this invention we employ a tank or cistern 1 in which is a gaso-
meter 2 free to rise and fall in the usual manner. In the top of the gasometer 2
as a hole 3 through which is passed a cylinder or vessel 4 supported and held in
position by means of the spindle 5, on the lower end of which is a chased boss 6
passing through a tapped hole 7 in the bottom of such cylinder or vessel 4, and
there is also a chased boss 8 at the top of the spindle 5, and this boss 8 passes
through a tapped hole 9 in a flanged cap or cover 10, and the outside of the spindle 5
is provided with a winged nut 11, riveted fast on the spindle 5. The bosses 6 and 8
are chased with right and left handed threads as shewn in the drawings, and below
the chased boss 6 is a pin or stop piece 12.
Inside the vessel or cylinder 4 is a perforated vessel 13 in which the calcium
carbide is placed, and such vessel 13 is provided with feet 14, and an inner concen-
tric tube 15 through which the spindle 5 passes. 16-16 are guides for steadying
and supporting the cylinder or vessel 4, and at 17 is a pipe leading from the interior
of the gasometer to the delivery pipe or valve and syphon 18.
The apparatus is shewn in duplicate and as the contents of one gasometer are
being withdrawn, the other can be charged. At 19 is a division plate dividing the
tank 1 and serving as a guide or steadying piece for both gasometers. 20 is a cover
or lid for the tank 1 which contains the whole of the apparatus.
The apparatus is charged by first removing the cover 20 then unscrewing the
nuts 21-21 and removing the cap or cover 10 lifting out the cylinder or vessel 4.
Calcium carbide is now placed in the vessel 13 in the vessel 4 and the hole 7 in the
bottom of the cylinder or vessel 4 is closed by the chased boss 6. The vessel 4 is
placed in the hole 3 and the latter is hermetically closed by screwing on the cap
or cover 10 between which and the edge of the hole 3 is a rubber ring or washer 22.
This is done before any water touches the calcium carbide and consequently before
any gas is generated. When all is made gas tight and secure, the spindle 5 is
turned in one direction by the winged nut 11, and the boss 6 is withdrawn from the
hole 7 and the cylinder or vessel 4 drops or falls until it is caught and stopped by
the stop pin 12, and water from the tank 1 rises through the hole 7 into the cham-
ber 4 and to the calcium carbide, and gas is generated and passes to the gasometer,
thence to the pipe 17. At 24-24 are small guide pulleys or runners for steadying
the gasometers.
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 general construction, arrangement, and combination of parts consti-
tuting the improved apparatus as and for the purpose herein described and sub-
stantially as illustrated by the annexed drawings.
(2) A gasometer 2 in which is a hole 3, and a cylinder or vessel 4 with an in-
ternal perforated vessel 13, and the chased spindle 5 all in combination as and for

page_text: the purpose herein described and substantially as illustrated by the drawings
annexed hereto.
(3) In acetylene gas generators an hermetically closed vessel or chamber which
can be opened when in situ by means of a chased spindle as herein described and
substantially as illustrated by Fig. 1 of the accompanying drawings.
