16 Claims.
'I'he object of our invention is to provide 'a
liquid storage device which is simple, durable and
comparatively inexpensive to manufacture.
A further object is to provide a storage tank
especially adapted for use in connection with a.
liquid dispensing device such as shown in our
copending'applications Serial No. 711,952, ñled
February 19, 1934 and Serial No. 737,062, filed
July 26, 1934.
More particularly, it is an object of our present
invention to provide a storage tank which is con
nectible with and disconnectible'from a, sump, the
sump being adapted for delivering oil or other
contents of the tank to a dispensing mechanism
or the like, the connecting mechanism between
the tank and the sump being of a predetermined
size and other tanks and sumps having similar
connecting devices of different sizes to insure the
proper association of a tank with a sump-that is,
to insure that a tank containing the wrong oil
will not be associated with a sump for a different
oil.
Another object is to provide a combined float
and check Valve connection between the sump
and the tank to indicate an empty condition of
the tank.
l
Still another object is to provide a closure
element for the tank which is automatically
opened by association of the tank with the sump,
the connection between the two having a sealing
ring which prevents leakage »of liquid while the
tank is being telescopically associated with the
sump after the closure element is opened.
Still another object is to provide an exhaust
n... valve connected in a line of communication be
tween the sump and the storage tank, the
storage tank having a vent to atmosphere so that
air exhausted thereinto can be in turn exhausted
to atmosphere.
Still another object is to provide a sump and
40
tank construction especially adapted for a liquid
dispenser such as shown in our copending appli
cations which admits air to the sump for forcing
oil therefrom to the dispensing mechanism and
opens the exhaust valve mentioned in the last
object after such forcing operation so that the

On the accompanying drawing, we have used

The lower end of the closure element |94 com

'I‘he air line |14 communicates with an exhaust
valve T having a valve seat 20| and a valve plug

the valve T is a flexible conduit 202 having a head

passing through the vent 2|0 to atmosphere.
The check valve |16 prevents the air escaping
from the sump |10 through the pipe line |14v and
the valve T from backing into the line |15 at a
time when there is to YbeV no air in this line.

Associated with the sump |10 is a track 2|2

Practical operation
As described in our co-pending applications,
compressed air is admitted through the pipe
line |15, the check valve V| 16 vand the valve T
t0 the sump |10 preceding the dispensing opera~
tion for the purpose of forcing a predetermined
45 -quantity of oil from the sump |10 to the dis
pensing mechanism.
After the predetermined
n quantity is so forced' from the sump, the com
pressed air behind the check valve |16 is ex
hausted to atmosphere and the actuator T’ is
50 charged with compressed airthrough the line
23.
Before the next dispensing operation com
be associated with the sump by placing the tank ‘
so that its telescoping element | 80 is supported
by the track 2|2, whereupon the lower end of the`
element |80 rests on the surface 2|6 with the
flanges 2|8 properly guiding it in a path toward
the element |94 as the tank is slid inwardly alongV 40
the track.
As the tank S is slid along the track the ele- '
ment |80 will finally drop off the left end of the
track and rest on the upper end of the element
|94. As the tank is then further slid along the
element |94, the element |80 will finally become
alignedi with the element |94 and will then slide
down or telescope over'it. At the beginning of
the telescoping movement the cross bar |96 of
the element |94 will be engaged by the lower end
of the pin |88 and the pin will then remain sta
mences the air is exhausted from the actuator
tionary, so that as the tank S settlesk into its
T'. With these steps of the dispensing operation
in mind. we will now proceed with the operation
55 of the storage device illustrated in the present ap
final position the pin will cup the disc |86 and
spring it out of the annular groove |84 of the
plication.
`
Assuming that the sump |10 has been almost
completely filled with oil by gravity from the
tank S, whereupon the oil has closed the com
60 bined check and float valve |98 to the positionA
shown in Figure 1V, air is then admitted to the
pipe line |14 for placing the oil in the sump
v under pressure to close the Valve |98 and force the
oil through the pipe |1| to the dispensing mech
As the oil lowers away from the float |98,

air in the sump |10 retaining it so seated.
sleeve |18.
'
YAs soon as the closure disc |86 isout of the
groove, oil will start ñowing, but before this, the
beveled edge |8| of the element |80 has passed
the sealing ring |90 to prevent any leakage of
liquid during the further telescoping movement
of the elements |80 and |94.
~
Finally the gasket |92 will seat against the up
per end of the element |94 and be compressed by
the weight of the tank and its contents to pre
vent leakage.

The disc |86 is inserted at the refinery where
the tank is ñlled with oil so that the tanks can
` be delivered in a sealed condition to the service
After the predetermined quantity of oil has station where the oil is dispensed, the seal being
