Thus, it is impossible for the plug 42 to be

Moreover, the plug 42 has to be removed before
the lever 36 is moved to valve opening position,

valve.
In Fig. 6, a construction is shown which can be
used with either of the embodiments illustrated
in Figs. 3 and 7 in which the safety valve em
ployed is a dill type valve rather than a safety
valve H, or in lieu of substitution of valves, the
safety valve shown in Fig. 6 could be used to
supplement the safety valve H by locating it
adjacent to the passage 2| in the stock of the
valve body shown to be sufficient for this purpose
in Figs. 4 and 2.
The safety valve 53 shown in Fig. 6 is dis
posed in the vertical passage 54 threaded at oppo
site ends thereof, as at 55 and 55, the tapering
seat 57 of the valve being disposed inwardly of
the threading 55 where the valve packing 58
and the valve itself are held in place by a valve
nut 59. In this particular embodiment the stem
?ll of the valve moves outwardly to open and
is disposed inside of the tank where it cannot
be tampered with. Opposing the outward move
ment of the stem 59 is a compression spring 6!
inserted through the threading 55 where it is
held under an adjusted tension by an adjusting
nut 62, the spring 6! augmenting the normal
tendency of the valve 53 to close. Thus, a safety
valve construction is provided which can be dis
posed within narrow dimensions in the stock of
the valve body to augment other Valves of dif
its inner spring which is not shown and flows
into the container, ?lling it to the desired point.
The supply of gas is then cut off, the connec
tion removed from the chamber 39, .the valve 25
closes and the plug 42 is put in place. While
the plug 52 may be fastened in any way, it is
preferable to fasten it by means of the chains
shown. Thus it cannot be lost when it is re
moved and the chains serve the additional pur
10 pose mentioned below.
When the full container has been taken to
the point of use, it is connected with a system
leading to the place where the fuel is to be burned
or the contents of the container otherwise used,
15 and this connection is made through the cham
ber 39 after the removal of the plug 42. Since
pressure from within the container normally
closes the valve 25, it is necessary to open it
before the contents can be discharged. Manual
means to do this include the lever 36, and the
cam or eccentric 38, the follower 33 and the
protector 38. Ordinarily when the container is
not in use and the plug 42 is in place as shown
in Figures 1, 2 and 3, the chain extends across
25 the handle of the lever 36 and holds it down
in the closed position. When a connection to a
system where the fuel is to :be used has been
made, the plug 1%2 has been removed and the
chain 64 is no longer over the handle 36. There
