PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Delivering and Recording
Measured Quantities of Liquid.
We, WALTER BRADNEY, of 18, Billiter Buildings, and HERBERT BARRINGER
of 88, Bishopsgate Street, both in the City of London, Consulting Engineers, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to apparatus for delivering liquids in measured quan-
tities and recording the quantity delivered, the said apparatus being especially
designed for use in connection with paraffin tanks but also applicable for other
purposes.
In carrying out our invention we make use of a measuring tank or vessel of
any desired capacity connected with a supply tank by a cock so arranged that it
serves for both the filling and emptying of the measuring vessel. In practice
we find it advantageous to make use of a plug cock, the plug of which is open at
one end and provided also with an opening designed to be placed opposite to the
inlet pipe or the discharge pipe, so that when the plug is in one position the
measuring vessel will be filled and when in the other position emptied, but so that
at no time is direct communication established between the supply tank and the
discharge pipe of the measuring vessel.
To permit of withdrawing only part of the contents of the measuring vessel a
draw off tap is arranged on the discharge pipe.
In connection with the plug cock before described we arrange a counting
mechanism so that each time the said cock is operated a record will be made of
the movement.
A pipe is arranged between the top of the measuring vessel and the supply
tank to allow the escape of air from the former during filling and the entrance
of air when withdrawing liquid and a float and valve are arranged in conjunction
with this pipe to indicate when the measuring vessel is full and at the same time
to close the air pipe to prevent the entrance of liquid into it.

We, WALTER BRADNEY, of 18, Billiter Buildings, and HERBERT BARRINGER
of 88, Bishopsgate Street, both in the City of London, Consulting Engineers, do
hereby declare the nature of this invention and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to apparatus for delivering liquids in measured quan-
tities and recording the quantity delivered, the said apparatus being especially
designed for use in connection with paraffin tanks, but also applicable for other
purposes.
In carrying out our invention we make use of a measuring vessel of any de-
sired capacity connected with a supply tank by a cock so arranged that it serves
for both the filling and emptying of the measuring vessel. In practice we find
it advantageous to make use of a plug cock, the plug of which is open at one end
and provided also with an opening designed to be placed opposite to the inlet
pipe or the discharge pipe, so that when the plug is in one position the measuring
vessel will be filled and when in the other position emptied, but so that at no
time is direct communication established between the supply tank and the dis-
charge pipe of the measuring vessel.
In connection with the plug cock before described we arrange a counting
mechanism so that each time the said cock is operated a record will be made of
the movement.
A pipe is arranged between the top of the measuring vessel and the supply tank
to allow the escape of air from the former during filling and the entrance of air
when withdrawing liquid and a float and valve are arranged in conjunction with
this pipe to indicate when the measuring vessel is full and at the same time to
close the air pipe to prevent the entrance of liquid into it.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which:
Figure 1 is a sectional side elevation of measuring apparatus arranged in
accordance with our invention; and,
Figure 2 is a rear elevation partly in section:
Figure 3 is a plan.

a is the measuring vessel having a capacity of, say, 1 gallon the said vessel
being adapted to be carried in connection with the main reservoir in any suitable
manner; in the drawing it is represented as being carried upon the tube b which
serves for conducting the oil from the supply tank to (the said measuring vessel.
cis the controlling cock one end d of which is connected with the lower end
of the supply pipe whilst the other end e serves for the discharge of the oil.
fis the plug of the controlling cock c the said plug being made hollow and pro-
vided with a single aperture and being adapted to place the supply pipe
communication with the measuring vessel or the measuring vessel in communi-
cation with the discharge end c. The plug f is designed to be operated
by a rod 'the upper end of which extends through a stuffing box in the cover i
of the measuring vessel a. and is provided with a handle h. With this arrange-
ment it will be understood that when the plug f is in the position shewn
in Figure 1 oil can flow from the supply tank through the pipe b into the
measuring vessel a and that when the plug is turned so that the opening 9 comes
opposite to the discharge end é of the controlling cock the contents of the said
measuring vessel will flow out. The opening g must be of such size that at no
time can direct communication be established between the supply reservoir and
the discharge end e of the cock. h³ Figure 3 is a projection on a boss 3 on the
rod h and h, h* are stops on the cover to limit the movement of the said projec-
tion and consequently of the plug f of the cock c.
jis a supplementary cock which we advantageously apply to the discharge end e
of the controlling cock c for the purpose of enabling a portion of the contents
of the measuring vessel to be withdrawn without rendering it necessary to operate
the plug f of the controlling cock until the measuring vessel has been com-
pletely emptied.
k is the counting mechanism which is of any suitable construction and as shewn
arranged upon the said cover i, the said mechanism being operated through the

page_text: medium of a rod 2 which works through a stuffing box and one end of which is
connected to the lever of the counting mechanism whilst the other end is passed
through a slot m in a cam plate n on the boss h³ upon the spindle h so as to move
therewith and thereby cause the rod to rise and fall each time the plug is
operated to fill and empty the measuring vessel a. In order to ensure the com-
plete emptying of the measuring vessel it will be noticed that we have
made the bottom of the said vessel concave and have also inclined it towards
the hollow plug of the cock.
o is the pipe through which the air is allowed to leave and enter the measuring
vessel a during the filling and emptying of the same, the said pipe being pre-
ferably extended into the supply tank. In this pipe o we preferably arrange a
sight chamber p, that is to say, a chamber the sides of which are composed
wholly or partially of glass and in this chamber we arrange a float q. This float
is adapted to slide upon a rod and as the level of the liquid rises in the
chamber p float upon its surface until it closes the opening of the pipe o at
the upper end of the said chamber P, as indicated by the dotted
lines in Figure 2. By the use of this float the entrance of oil into
the portion of the pipe o above the chamber p is prevented so that
at all times the quantity of liquid which can enter the vessel a
the same notwithstanding variations in the height of the liquid in the supply
tank.
is
It will be obvious that a double measuring vessel may be employed so that
while cne is being emptied the other will be filled so that there will be no inter-
ruption in drawing off large quantities.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:—
1. In apparatus for delivering measured quantities of liquid and recording the
quantities so delivered, the combination with a measuring tank of a cock for
alternately placing the said measuring tank in communication with the supply
tank and with the discharge aperture or spout, substantially as described.
2. In apparatus for delivering measured quantities of liquid and recording
the quantities so delivered and wherein a cock is arranged in conjunction with a
measuring vessel in the manner referred to in the preceding claiming clause, the
combination with the said apparatus of an air inlet and escape pipe and of counting
mechanism, substantially as described.
3. The manufacture and use of the improved apparatus for delivering measured
quantities of liquid and recording the quantities so delivered, constructed and
arranged substantially in the manner hereinbefore described and illustrated in the
accompanying drawings.
