This specification consists of a water & gas holder accompanied by two carbide
holders; the claim is as follows, water enters the ball tap A from water works,
or the water can be pumped in by the hand pump B into the water & gas holder C
until it reaches the water line D, Z is a water gauge to assume the height of
water, the thumb screw E is now slacken & the spring F opens the valve G water
then enters one of the carbide holders H through the pipe I, gas is then generated
& finds its way through the pipe J into the gas holder C through the regulator K
& then to the burners. When the gas holder is sufficiently full the pressure of
gas lifts the piston L & closes the water valve G, then the gas is stopped from
being generated. As the gas is being consumed the pressure falls back, the
valve G automatically opens by the spring F, & water flows to the carbide again
& gas is generated until there is sufficient pressure to stop the valve again.
When one of the carbide holders is exhausted the pressure falls so low, that the
spring M presses back the piston N carrying the rack O with it, which is in gear
with the tooth wheel 1', the water has then been automatically shut from the
exhausted carbide holder & turned into the fresh carbide holder by means of
the two cocks QQ. Whilst one is open the other is shut, the teeth are cut in the
rack in such a manner that when the piston N descends with the pressure of gas
behind it, it shall slip over the teeth of the cocks without moving them, it then
stops at the end of its stroke until the carbide holder is exhausted.
Then it returns again shutting the water off from one & turning it into the
other, the rack is kept in gear with the tooth wheel I', by means of the spring Y,

GARNET KELLAWAY, Hotel Road, St. Austell, Cornwall, Engine Fitter, I 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 follow-
ing statement:-
The drawings left with the Provisional Specification are the same as referred
to in the Complete Specification.
There are 2 carbide holders & 1 water & gas holder, the water enters into the
tank from the ball tap A from water works (or the water can be pumped in by
the pump B until it reaches the water line D). The screw E is now slackened
the spring F presses down the piston & rod which opens the valve G, water then
enters one of the carbide holders H & gas is generated. The gas finds its way
through the valve S & into the tank c through the regulator K & off to the
burners. The gas can be obtained at any moderate pressure by loading the
regulator K & tightening the screws W. (There is a water gauge Z fixed to the
tank c to assume the height of water.) The pipes which are connected from the
carbide holders to the tank c are made of indian-rubber so as to enable the covers
of the carbide holders to be removed easily, & it also acts as a safety appliance in
case of any of the apparatus going wrong, an excess of pressure would burst the
pipes to prevent any further damage. The valve at S are to prevent the escape
of gas whilst the carbide holders are recharged. The cylinder & the rack O
together with the two cocks Q Q are an automatic gear for supplying the carbide
holders with water. The two cocks Q & Q are geared together by tooth wheels
in such a position that when one of them is open the other is closed; the water
then flows to one carbide holder & generates gas. When there is sufficient gas
generated, the piston L lifts, & closes the valve G, which turns off the water-
supply from the carbide. The spring M being slightly weaker than the one at F
the pressure of gas causes the piston N to descend before the piston L ascends.
The teeth in the rack are made so that when it descends it shall slip over the
tooth-wheel P which is kept from revolving on the downward stroke of the rack
by the pawl 6, until it comes to the end of its stroke; there it stops until the
holder that is in action is exhausted. The pressure of gas thus falls so low that
the spring M presses back the piston N, carrying with it the rack 0, which is
kept in gear with the tooth-wheel P by the spring Y, causing the wheel to revolve
a quarter of a revolution, thus shutting the water from the exhausted holder &
turning it into the fresh holder. Gas is generated again & the pressure over
powers the spring M & the piston X descends again at the end of its stroke without

exhausted holder is recharged whilst gas being generated in the fresh holder.
The water supply to the carbide is regulated by the valve G. When there is
sufficient pressure in the tank, the piston L lifts & closes the valve G, which
cuts off the water supply until the pressure falls back; then the spring opens
it again. The valve at a is to prevent the escape of gas whilst the water is being
pumped in. The gas outlet is fixed at K¹. When the regulator is sufficiently
full, the lever U which is connected to the cock V is lifted by the top. of the
regulator K, thus turning off the gas from the tank c; this arrangement causes
an equal pressure of gas in the out-let pipe at K. The pistons of the cylinders
are made cup shape, the same style as used for hydraulic work. The cylinder N¹
& the two branch pipes are cast in one piece with one end of the cylinder open &
a cross stay to keep the spring in place; it also acts as a guide for the piston
rod; this stay is fixed to the cylinder by two set screws screwed into two ears
cast on the cylinder N¹. The end of the pipe J is screwed into a fixed nut which
is fastened to the tank c. The pipes from R to R are made of indiarubber.
The two carbide holders are made of cast iron, & the joints of the covers are
faced cone shape & ground to make a tight joint. The rubber pipes are put on
tight over some little nipples which are cast on the covers to receive them. The
ends of the regulator K are stamped out of a thin metal suitable for the purpose
& recesses blocked in them to receive the ribs of the ends of the rubber casing T
which fit tight on them. The guides 2 are rivetted on to the bottom of the
regulator. The frame 3 which carries the rollers 4 are rivetted to the top of the
regulator K, the bottom of the regulator is fitted on over the cock V & kept in
place by the nut 5. The cock V is screwed into a nut which is soldered to the
tank c.
The ball tap A is screwed into a nut which is fixed to the tank & made
sufficiently large so as to enable the float to pass through it. The end of the cast-
ing which carries the valve seating G is screwed into a nut which is fixed to the
tank c, in the bottom of this casting there is a plug fitted, so as to enable the
seating to be machined, & the valve put in place. The cocks Q & Q & the
seating G are cast in one piece. The holes in the plugs which fits into the
cocks Q&Q are made long & very narrow, so that no water shall pass through
them until they have turned in a position at right angles from what they were
before shifted. The pawl 6 is to prevent the cocks Q & Q from revolving in
the wrong direction.
The valve seats at S are machined on the covers of the holders H. The covers
are kept in place by the hand screw & dog H. This generator can be made in
any size & of any metal except copper. From A to B is where the section is
taken looking in the direction of the arrow. I do not now propose or claim to
construct the apparatus with the two parts indicated B & Z.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, declare that what
I claim is:-
(1) An acetylene gas generator which automatically feeds itself with water
from any water-works.
(2) This generator gives a regular supply of gas & there being no waste owing
to the interior of the generator having no communication with the atmosphere.
(3) Either of the holders H can be recharged whilst gas is being consumed at
the burners.
(4) The combination as a whole.
