page_text: I FREDERICK WILLIAM LEVIERGE Maker of Model Engines et cet of 369 Ken-
nington Road in the County of Surrey do hereby declare the nature of this
invention to be as follows:-
It consists in a new means of & apparatus for measuring off measured quanties
of liquids from casks or other reservoirs it is more especially designed for the
retail sale of liquors but may be employed in other businesses & in the arts.
The apparatus may either to first measure & then draw of a given quantity of
the liquid or with slight modifications it may be used to measure the liquid as it
flows out. These modifications I shall call my second Improvement in any case
the apparatus consists mainly in a tap with three ways one leading from the cask
et cet another being the outflow and a third leading upwards into a graduated glass
or other transparent measure in one position of the plug the liquid flows from the
cask et cet and rises in the glass when its height in the measure marks the desired
quantity the plug is turned to the other position thus opening a way from the
measure to the outlet and through this the measured quantity escapes. It will be
seen that this later is the normal position of the plug & I prefer to provide a
spring for promptly returning it to this position when the liquid reaches the
desired height in the measure such spring may conveniantly be a clock spring and
may be enclosed in a suitable box. My second improvement consists as has been
said in a modification of the above, whereby I am enabled to measure the liquid as
it is drawn off thus saving considerable time, for this purpose I close the top of the
measure entirely with the exception of a vent hole to which is fitted a valve
opening downwards this admits air and renders it possible to draw the liquid out
of the measure while by means of a float I close the valve when the measure is
full under this improvement the normal position of the tap is reversed and the
action of the spring if used must be reversed accordingly, keeping the measure in
communication with the cask et cet, the liquid from which fills it while the float
closing the valve stops the flow when it is full-I can now by turning the tap

page_text: draw off any desired quantity measuring downwards and on turning the tap back
again the measure is immediately and automatically filled again ready for use
I sometimes construct this form of apparatus in double so that while the liquid is
being drawn out of one measure it is flowing into the other & vice-versa A single
tap with suitable ways may be made to control the double operation for a two
way tap I sometimes substitute a pair of valves to close alternately the openings
to the cask & the outlet that leading to the measure is, it will be observed in any
case allways open it will be seen then that my invention consists substantially in
a two way tap or similar device & the transparent measure fitted as & for the
purposes above set forth.

page_text: I, FREDERICK WILLIAM LEVIERGE, Maker of model engines & of 369 Kennington
Road, in the County of Surrey do hereby declare the nature of my invention for
DRAWING OFF MEASURED QUANTITIES OF LIQUIDS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement (reference being had to the accompanying drawing):
My invention consists of a new means of and apparatus for drawing off measured
quantities of liquids from casks and other reservoirs. It is more especially
designed for the retail sale of liquors but may be employed in other businesses
and in the arts. The apparatus may be used either to first measure and then
draw off a given quantity of liquid or with slight modifications it may be used to
measure the liquid as it flows out. These modifications I shall call my second
improvement. In any case the apparatus consists of a tap with two ways, one
leading from the cask or other reservoir into the graduated glass or other
transparent measure, the other being the outflow. In one position of the plug
the liquid flows from the cask & and rises in the glass vessel. When its height
in the measure marks the desired quantity the plug is turned to the other position
thus opening a way from the measure to the outlet and through this the measured
quantity escapes. It will be seen that this latter is the normal position of the
plug. My second improvement consists as has been said in a modification of the
above whereby I am enabled to measure the liquid as it is drawn off thus saving
considerable time. For this purpose I close the top of the measure entirely with
the exception of a vent hole F figure 1 to which is fitted a floating valve E
opening downwards. This admits air and renders it possible to draw the liquid
out of the measure while by means of the same floating valve I close the vent hole
when the measure is full. Under this improvement the normal position of the
plug is reversed keeping the measure in communication with the cask & the
liquid from which fills it while the floating valve closing the vent hole F stops
the flow when it is full. I can now by turning the tap draw off any desired
quantity (measuring downwards) and on turning the tap back again the measure
is filled automatically again ready for use. In some cases I employ a spring to
automatically return the plug to its normal position. I sometimes construct this
form in double so that while the liquid is being drawn out of one measure it is
flowing into the other and (vice versa) The plug when in mid position shuts off
communication with both supply and delivery. A single tap with suitable ways
may be made to control the double operation. For a two way tap I sometimes
substitute a pair of valves attached to a piston figures 4 and 5 to close alternately
the opening from the cask and the opening to the outlet, that to the measure being
always open.
It will be observed that my invention consists substantially in the
combination of a two way tap or a similar device and the transparent graduated
measure fitted as and for the purposes set forth above.

page_text: the opening C from the reservoir for filling the globe A and the passage D for
emptying the measure when in the required position as shewn in Figure 3 and
closing the supply from the reservoir E is a floating valve which by means of a
glass ball to which the valve is attached floats on the top of the liquid when the
measure is full and closes the air vent F Figure 4 is a modification shewing
a push valve which by means of a spring G returns the valve to its normal
position & refills the measure. Figure 5 shews the same cock in the act of
discharging the measured quantity and the supply from the reservoir closed.
Figure 6. shews another modification of the same in which the respective
operations of filling & emptying are done at the same time. Fig. 7 is a cross
section of the same. Figure 8 shews a funnel graduated in a similar manner to
the measurer.
"
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
A combination of a two way tap or similar device and a graduated vessel with
or without a floating valve the combination thus forming an apparatus for drawing
off measured quantities of liquids I do not claim the seperate items: (viz) a two
way cock, a graduated transparent vessel, or a floating valve but I claim the
combination as specified above.
