PROVISIONAL SPECIFICATION.
Improvements in the Means for Measuring Liquids.
I GEORGE HERBERT TIMMIS of the Croft, Old Swinford, Stourbridge in the
County of Worcester, Mining Engineer, do hereby declare the nature of this
invention to be as follows:-
:―
The objects of my invention are practically the same as those described in my
previous Patent No. 19273 of 1889 and the reasons therein stated are the same but
this invention is an improvement thereon.
I have been able to improve the details of the tap or cock in its working. I have
found that in the previous Patent there is a difficulty in getting rid of the air in the
inner chamber when it is being filled and I have devised the following means which
I find get over this difficulty and thus the tap can be worked much more quickly
and more reliably.
At the top (or near thereto) of each chamber in the tap or cock I put an air
valve which falls down any required distance when the chamber is not full thus
leaving an opening for air to come in or go out.
This valve has attached to it a piece of wood or cork or other suitable substance
or an air tight hollow vessel (which may or may not contain a vacuum) which as the
chamber is filled with liquid rises and closes the valve and stops the inlet and outlet
hole (one or more).
The hole or holes may be any shape and put in any convenient part of the
chamber. The valve or valves may be of any available and convenient shape and size.
It is clear also that the valve acts as a means to introduce air into the chamber
that has to be emptied and instead of or addition to the hole mentioned in the
above, named Patent.

COMPLETE SPECIFICATION.
Improvements in the Means for Measuring Liquids.
I, GEORGE HERBERT TIMMIS of the Croft, Old Swinford, Stourbridge in the
County of Worcester, Mining Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :---
The objects of my invention are practically the same as those described in my
previous Patent No 19273 of 1889 and the reasons therein stated are the same but
this invention is an improvement thereon.
I have been able to improve the details of the tap or cock in its working. I have
found that in the previous Patent there is a difficulty in getting rid of the air in the
inner chamber when it is being filled and I have devised the following means which
I find get over this difficulty and thus the tap can be worked much more quickly
and more reliably.
At the top (or near thereto) of the tap or cock on the inlet side I put an air
valve which falls down any required distance when the chamber is not full thus
leaving an opening for air to come in or go out.
This valve has attached to it a piece of wood or cork or other suitable substance
or an air tight hollow vessel (which may or may not contain a vacuum) which as
the chamber is filled with liquid riscs and closes the valve and stops the inlet and
outlet hole (one or more).

page_text: The hole or holes may be any shape and put in any convenient part of the
chamber. The valve or valves may be of any available and convenient shape
and size.
It is clear also that the valve acts as a means to introduce air into the chamber
that has to be emptied and instead of or addition to the hole mentioned in the above
named Patent.
My invention will be best understood by means of the accompanying drawing
which represents a vertical section of my improved tap for measuring liquids.
The plug A consists of two chambers a and each of which can be alternately put
into communication with the inlet B and outlet C by turning the handwheel D.
The lid E is provided on the inlet side with a small auxiliary chamber F
containing a float which can close the hole in the lid G of the auxiliary
chamber F. The bottom of this auxiliary chamber F is provided with one or more
ducts d, d corresponding to two others drilled in the body of the cock so that this
auxiliary chamber is always in communication with one of the chambers in
the plug.
The outlet side is also provided with a duct e which ensures a communication
between the atmosphere and the plug chamber on the outlet side.
The working of the invention is as follows. When the plug chamber a on inlet
side is being filled with liquid the air escapes through ducts d, d until the liquid
rising in the auxiliary chamber raises the float and thus closing the hole h. By
turning the hand wheel D half a turn the filled up chamber a is brought into
communication with the outlet C and the liquid empties itself assisted by the air
flowing through the duct e.
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:
In a double chambered tap for measuring liquids the application on the inlet
side of an auxiliary chamber containing a float valve and communicating with the
top of one of the chambers for the purpose of allowing the air to escape when the
said chamber is being filled substantially as and for the purposes herein before
described.
