in the tank and through the burner-pipes.
The passages in valves I3 and C4 are made
with narrow slotways through the two por-
tions of a turn-valve or of other suitable
5 formso as to be quick-acting, or to open and
shut off by very short movements when re-
quired.
The tank B is made of two shells concen-
tric, with a water-space between for the top
io B' to slide in
The pipe I has a branch 1,projecting into
tank B and rising therein above the highest
level of the water, so the gas can pass in and
out freely.
15 A quantity of suitable carbid is placed in
the shell GI and replaced in the generator
and the lid closed tightly by screw GI Wa-
ter is fed into chamber C'. The water then
passes by pipes C2 and C3, by lifting a valve,
20 into the shell G iin the generator G through
an annular space onto the carbid, so as to pro-
duce gas. The gas passes out of the genera-
tor by passage 17 by lifting valve J2, and on
into branch I' and then into and along pipe
25 I to the several burners in use. If the gas
generates faster than it is used, the pressure
increases until it lifts the top B' and until
the top lifts the chain B3. This turns the
lever of valve C4, so as to ctt off the water to
30 stop the formation of gas. This chain also
turns the lever of valve I1, so as to cut off
the gas from tank B and the burner-pipes, so
as to prevent too high pressure therein If
there should be an excess of water in the gen-
3S erator, or if by any chance the pipe should
leak into it, then the excess of gas formed
would go into the tank C, which is made
strong enough to hold the gas at any pressure
within the capacity of one charge of carbid
40 to form and hold it without increasing the
pressure at the burners when the gas is used
out until the top B' lowers and opens valves C4
and I3 by chain 133. This lets gas out of tank C
and generates more gas until the top B' rises,
45 so as to lift the chain and cut the gas off
again. When all is working well, the gas
will be at nearly a uniform pressure throughall the parts, and the generation will go on
nearly as the gas is used; but to insure this
and avoid all accidents the apparatus is made 50
with the several parts for automatic control
and with an expanding tank for gas at a regu-
lar pressure for use and with a pressure-tank
for storing any excesses and feeding back as
required. 55
Various modifications may be made.
I claim-
1. In combination a generator adapted to
form gas from a carbid and water, and pro-
vided with a service-pipe, with two tanks, 6o
connecting with such generator and pipe, one
adapted to expand and contract to accommo-
date variations between the generation and
use of the gas, at a pressure near that in-
tended for the service-pipe, and the other 65
adapted to receive and feed the excesses of gas
at varying pressures, and with four valves,
two turn - valves with means for operating
them from excess of gas in the charging-tank,
adapted one to control the admission of gas 70
to such tank and the other of water to the
generator, and two check-valves adapted to
prevent outlet of gas from the generator by
the water-passage, and from the gas-holder
to the generator, substantially as set forth. 75
2. A generator constructed to form gas
from a carbid and water, having a removable
cell to facilitate charging and discharging, a
removable cap having a stirrup and screw-
holder, and two passages in the wall of the 8o
generator each provided with a ball or check
valve adapted to allow the passage of water
inward by one, and of gas outward by the
other, while preventing the escape of gas by
reverse passage, in combination with an ex- 85
pansible and a non-expansible gas-tank and
service-pipes connecting the generator and
the tanks, and provided with automatically-
controlled valves, substantially as set forth
