I; designates a valve located in the pipe C
and is shown closed, 1Whereby the water in
I he tank D' is prevented from flooding the
generator when the carbid has become ex-
5 hausted and the bell I' passed below the
normal hne.
G' designates the gas-outlet pipe leading
from the generator to the pipe G and the
burner E The pipe G' connects the genera-
1O tor at a point midway or below the carbid-
basket, whereby the gas in passing from the
generator is caused to pass downwardly
through the carbid, and thereby be more or
less dehydrated. The pipe G' is provided
15 with the usual check-valve g, which allows
the gas to pass from the generator to the pipe
G', but prevents the return of the gas when
the generator is opened for recharging or
cleaning.
20 G4 represents a purifying-chamber located
within the pipe G' and filled with cotton,
cloth, sand, or similar material dampened
with some non-volatile hydrocarbon, so as to
catch and retain atoms of heavy hydrocar-
25 bon in the I resh gas, to which are attributed
the tendency to form specks of soot in burn-
ing and clog up the burner-tip in use.
G2 designates a pipe connecting the pipe G
and leading to the interior of the gas-holder
30 or bell, and it also acts as a tie-rod for secur-
ing the heads of the tank K against internal
pressure within the outer tank of the gas-
holder, as clearly shown. G3 designates a
pipe connecting the pipe C with the interior
35 of the gas-reservoir K for conducting the
high-pressure gas to the said reservoir here-
inafter described.
F2 designates an escape-pipe which leads
to the external air, a chimney, or other place
40 of safety and is connected to the pipe G3and
provided with a weighted safety-valve F'
F designates an internally-weighted valve
and is located in a branch pipe connecting the
pipes F2 and G2. The object of the safety-
45 valves F F' is, the first, to relieve excess of
pressure in the holder H, and, the second, to
relieve excess of pressure in the reservoir K.
I designates a turning plug located in the
water-supply pipe C and gas-supply pipe G
50 and is used for regulating the supply of water
from the tank D' to the generator and for
regulating the passage of gas from the genera-
tor to the burner and gas-holder. The valve
I is provided with lever-arms I'12, to one end
55 of which the chain z is attached, the opposite
end being weighted by any suitable means in
a well-known way, whereby the valve is nor-
mally held open.
L' designates an upright post which may
6o or not be secured to the gas-holder tank. To
the upper end of this upright is hinged a
lever-arm L, carrying intermediate its ends
idle-wheels 1' l, over which passes a chain ',
which is secured at one end to the bell H'
65 and at its opposite end to one end of the
lever-arm of the valve I, whereby the rise
and fall of the bell automatically controlsthe valve I and correspondingly regulates
the supply of water to the generator and the
passage of the gas therefrom to the burner. 70
At or near the end of the lever L is secured
a chain a2, passing down and connected to the
lever M2. A bucket C', provided with a bail
c, is also connected to the lever L and dips
into the tank D. A chain 2' also connects 75
the lever L and arm I4 of the valve 13 to
limit the downward movement of said arm
and at the same time assure the closure of the
valve P.
Operation: In the operation of my appara- 8o
tus as above described the generator having
been charged with carbid and the tank D
with water, the bell H' being in its lowermost
position and the valve I turned to open both
pipes C and G, the valve 13 is manually op- 85
rated by the lever I4 to permit water to
pass to the generator through the valve I and
spray-pipe B2, whereupon acetylene gas is
instantly generated and conducted to the
burner E and burned, the excess gas passing 9o
to the gas-holder II through the pipe G2 and
stored therein until said holder is raised suf-
ficiently high to close the valve I, when the
supply of water to the generator and the pas-
sage of the gas from the generator direct to 95
the burner through pipe G will be cut off.
The gas for the burner or burners, more or
less, as found wanting, will then be taken
from the holder until said holder descends
sufficiently to again open said valve I to sup- mo3
ply more water to the generating-chamber.
Thus it will be seen that the generation of
gas is continuous and automatically regu-
lated. The valve I3 is maintained in an open
position by the bell and only closed when the 105
bell passes to its lowest position, thus pre-
venting the flooding of the generator.
It is a well-known fact that in this class of
gas-generators gas will continue to be gener-
ated for some time after the water-supply to iio
the generator has been cut off. This is due
largely to the hygroscopic character of the
carbid and the excess of water admitted to
the generator in the first instance and re-
tained by the hydrate in contact with the 115
carbid. In order to make provision for the
storage of gas so generated, a reservoir K has
been provided, to which such gas is conduct-
ed through the pipe G3, which gas upon the
opening of the valve I passes to the burners 120
and holder H.
As shown in the drawings, Fig. 1, the bucket
C' is in its lowermost position in the water-
tank D. Upon the rise of the bell the dome
thereof coming in contact with the lever L 125
raises said lever and with it the bucket C',
which latter in rising is caught by the trip d
and bail c and emptied in chamber D', thus
supplying said chamber with the necessary
water for the generation of gas. At the same 130
time and through the chain t2 the lever M2
is raised and by it a rocking motion imparted
to the rock-shaft M', and the basket contain-
ing the carbid is agitated to free the carbid
