Improvements in and connected with Apparatus for the Production
and Utilization of Acetylene Gas.
I, JOHN VAUGHAN-SHERRIN of 28 Victoria Street, London, S.W., Electrical
Engineer, do hereby declare the nature of this invention to be as follows:-
From
A series of vessels each containing a charge of carbide of calcium are used as
generators of acetylene gas, and each charge is exhausted into a gas bag before the
next of the series is filled with water. The carbide in small pieces is put into these
vessels which are cylindrical or otherwise and provided with perforated false bottom
and with bottom inlet neck and top outlet neck having screw thread or bayonet joint
or other joint appliance for quick connection and disconnection. As the water is
charged in from below acetylene gas is developed which is passed through a condenser
with drip tap or trap and then into a gas bag so as to expand it; the bag may be
provided with weight or springs as required to cause it to tend to collapse.
the gas bag the gas is passed through a chamber filled with wire gauze or shot to
prevent the issuing flame from striking back. As the bag collapses a bell or gong is
sounded or other signal made, and a fresh carbide vessel is connected automatically
or by hand. The water may be charged in by a pump or from a measuring vessel
sliding on a pipe in a water supplied cistern so that when the measuring vessel floats
upwards or is raised by a connection to the collapsing gas bag it discharges into a
hole in the said pipe which leads to a carbide vessel. The carbide vessels or
generators may be supplied to customers charged with the carbide and be returned
for charging or thrown away. Or I provide a water container with a number of
carbide vessels connected to its lower part by means of taps, which are opened one
by one as required. The gas evolved then rises through the water and passes to the
gas bag.
In some cases two or more gas bags may be employed.
My invention is very applicable to motor cars all handling of the carbide is
avoided, and the gas bag forms a light and convenient holder or store for gas for a
limited period of time.

Improvements in and connected with Apparatus for the Production
and Utilization of Acetylene Gas.
I, JOHN VAUGHAN-SHERRIN, of 28 Victoria Street, London, S.W., Electrical
Engineer, do hereby declare the nature of this invention and in what manner the
C

page_text: same is to be performed to be particularly described and ascertained in and by the
following statement:-
A series of vessels each containing a charge of carbide of calcium in small pieces
are used as generators of acetylene gas and each charge is exhausted or the gas
evolved therefrom passed iuto a gas bag before the next of the series is filled with
water. The generators are made of a size convenient for handling and are by
preference adapted for quick attachment to and detachment from the lower part
of the water supply vessel a tap being provided for each. These taps are opened
one by one as required and the gas evolved passes up through the water and then
into the gasbag so as to expand it at a low and safe pressure. The bag may be
provided with weight or springs as required to cause it to tend to collapse. From
the bag the gas is passed through a chamber filled with wire gauze or shot to
prevent the issuing flame from striking back: Instead of a bag I may use a
telescopic or other gas holder. As the bag collapses (or the bell descends) an
electric bell or gong is sounded or other signal made and a fresh carbide vessel
should then be connected by opening its tap to the water supply vessel. Or the
taps are turned on automatically one by one. The generators may be supplied to
the customers charged with the carbide and be returned for recharging, or if of a
cheap form may be thrown away when the carbide charge is exhausted.
My invention is very applicaisle to motor cars all handling of the carbide is
avoided and the and the gas bag forms a light and convenient store for gas for a limited
period of time.
Fig. 1 of the accompanying drawings is a side view and
Fig. 2 an end view of one construction of apparatus.
Fig. 3 is a side view of a generator.
Fig. 4 is a side view of another construction of apparatus and
Fig. 5 a side view of yet another construction.
In Figs. 1 and 2 the carbide containers or generators B are by taps H connected
to the bottom of the water cistern A and are surrounded by the water in a tank L
which is hooked on or otherwise arranged so that it can readily be lowered out of the
way of the generators when the latter have to be recharged. The cistern A bas n
air outlet tap M and a gas outlet tap K which by a pipe N connects with a collapsible
gas bag (). This bag has a weighted top 01 with ears that in the descent and ascent of
the gas bag (when collapsing and expanding) are guided in the rods P. One of
these rods has a metallic ring Q insulated from the rod. When the bag collapses
so far as to bring the ear of the top 0' in contact with the ring Q an electrical
circuit is closed whereby a bell R is set ringing to advise the attendant that one
generator B is exhausted and that the next tap H has to be opened to admit water
into its generator B. When first starting the air tap M is opened until the gas
driven out the air.
has
Fig. 3 shows one form of generator with a screwed cap B at one end.
Fig. 4 shews a water cistern A (or combined water cistern and gasholder) mounted
in a frame D and caused to rotate by worm E and worm-wheel F. G is a stop on
the frame for opening one tap H after another as they come round, thus connecting
one fresh carbide vessel B after the other. K is the gas outlet pipe to a gasbag it is
provided with gas tight rotatable joint. The shaft of the worm E is put in motion
whenever by the collapse of the gasbag, a clutch on the said shaft is by electrical or
mechanical connections caused to engage with and be driven by the carriage motor
or carriage axle.
Fig. 6 shews a water cistern with telescopic gasholder bell A. The generators B
are arranged all round the lower part of the cistern A, and as the gas in the latter
is consumed the hell A¹ descends more and more, and the rods I which also serve as
guides for the bell operate the handles of the taps H to open them one after the
other as they are placed at varying levels. Or the generators B may be placed at
the same level and the rods may be of varying lengths. The bell having opened
the lowest tap is a sign that a charged set of generators B have to be attached and

page_text: that another charge of water has to be a Imitted into the cistern A whereby the bell
is again raised to its original position. The flexible outlet pipe K leads to the motor
or other gas consumer.
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. In acetylene making apparatus the combination of a water cistern, a series of
carbide containing generators attached to the lower part of it, taps for connecting
the cistern with the generators a gasbag or other gasholder and means for ensuring
the putting one generator after the other in communication with the water cistern
as required, substantially as set forth.
2. In acetylene making apparatus the combination of a water cistern a series of
carbide containing generators attached to the lower part of it, taps for connecting
the cistern with the generators, a gas bag or telescopic gasholder and an electric-
signalling device operated by the collapse of the gas bag or the descent of the
gasholder bell for indicating that a fresh generator tap has to be opened, substantially
as set forth.
3. In acetylene making apparatus the combination of a water cistern, a series of
carbide containing generators attached to the lower part of it, means for slowly
rotating the cistern, taps for connecting the cistern with the generators and a stop
for opening one tap after the other as required as the cistern rotates, substantially
as set forth.
4. In acetylene making apparatus the combination of a water cistern a series of
carbide containing generators attached to the lower part of it, taps for connecting
the cistern with the generators, a gasholder bell adapted to work in the cistern and
rods on the bell for opening tap after the other as the bell descends in consequence
of the gas being consumed, substantially as set forth.
5. The constructions of acetylene making apparatus shewn on the drawings.
