PROVISIONAL SPECIFICATION.
Improvements in Measuring and Registering Taps or Valves.
I, JAMES BARKER, of 142 Cross Bank Street, Oldham, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
-
My invention relates to the taps or valves employed for drawing off liquids in
different quantities or measures from barrels and other vessels, my object being to
automatically register the quantity of liquid withdrawn and at the same time if desired
record the value.
My improved tap is formed with a hollow plug large enough to contain the maximum
measure to be withdrawn at one operation, this plug is fitted in a casing to which is
secured the recording apparatus the casing being connected to the vessel containing the
liquid.
The plug has an opening which places it in communication with the vessel while
the delivery or discharge pipe of the tap is closed, so that the plug is maintained
normally full of liquid and when full a float air valve closes the tap against the
atmosphere.
The plug has any required number of slots to allow varying quantities of liquor to
pass through the tap, and the handle or valve mover is geared or otherwise arranged
to operate registering mechanism which indicates the quantity or value, or both, of
the liquor, according to the distance the handle is moved.

COMPLETE SPECIFICATION.
Improvements in Measuring and Registering Taps or Valves.
1, JAMES BARKER, of 142 Cross Bank Street, Oldham, in the County of Lancaster,
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 :—
My invention relates to the taps or valves employed for drawing off liquids in
different quantities or measures from barrels and other vessels, my object being to
automatically register the quantity of liquid withdrawn and at the same time if desired
record the value.
My improved tap is formed with a hollow plug large enough to contain the maximum
measure to be withdrawn at one operation, this plug is fitted in a casing to which is
secured the recording apparatus the casing being connected to the vessel containing
the liquid.
The plug has an opening which places it in communication with the vessel while the
delivery or discharge pipe of the tap is closed, so that the plug is maintained
normally full of liquid and when full a float air valve closes the tap against the
atmosphere.
The plug has any required number of slots to allow varying quantities of liquor to
pass through the tap and the handle or valve mover is geared or otherwise arranged
to operate registering mechanism which indicates the quantity or value, or both, of
the liquor, according to the distance the handle is moved."
And in order that my invention may be fully understood and readily carried into
effect. I will describe the accompanying sheet of drawings reference being had to the
figures and letters marked thereon.

page_text: Fig. 1 is a side sectional elevation. Fig. 2 a front elevation and Fig. 3 a plan of a
measuring and registering tap made according to my invention and Fig. 4 is a
sectional plan or diagram illustrating the relative positions of the delivery slots in
the plug..
In these views a designates the valve casing, 6 the supply pipe in this case shown
fitted with a tap c, d the delivery pipe or spout, and e the hollow plug which is fitted
within the casing a and is turned by a handle. The plug e has an opening e
which when the handle is in the position indicated on the drawings places the
interior of the plug in communication with the supply pipe 6 while the plug is closed
against the delivery pipe d. At the top of the plug e is fitted a float g and an air
valve which as the plug fills with liquid is lifted off the wires i and gradually
raises the valve against its seating to allow the air to escape from the plug as the
liquid enters, until when the plug is full the float g reaches the position shown in
Fig. 1 the valve is closed against the atmosphere. When however any liquid is
drawn off from the tap, the float and the valve begin to descend thereby allowing
air to enter through the holes in the cap and to pass through the valve
into the plug e. In this case the plug e is shown provided with four slots e² e³ et es
respectively which are formed at different levels to permit varying quantities of liquid
to be drawn from the plug e according to the particular slot which is brought
opposite to the groove or recess a¹ in the valve casing which forms a passage to the
spout d. On the underside of the handle is fixed a rack which gears into a spur
wheel m which operates suitable registering mechanism and moves the indicating hand
contained in the dial case n whenever the handle is moved from left (the position
shown) to right to open the tap. On the upper side of the handle fis fitted a spring
catch o which engages one or other of the notches in the plate p the notches being
suitably marked say 0, 2, 3, 4, and 6 as shown or otherwise to indicate that the tap is
closed when the handle is in one position and the quantity or value of the liquid being
drawn when the handle is in other positions.
In operation when the handle is in the position shown with the spring catch o
resting in the first notch marked zero the tap is closed as neither of the slots in the
plug e is in communication with the discharge passage a¹; but as soon as the handle
is moved to the right and the catch o enters the second notch marked 2 the inlet
opening e will have been moved away from the supply pipe 6 while the slot e² will
have been brought opposite the passage a¹ and liquid will be delivered from the tap
through the spout d until the level of the liquid within the plug e has reached the
bottom of the slot e² and the quantity or value of the liquid thus withdrawn will have
been recorded through the forward movement of the handle causing the wheel m to
actuate the registering mechanism. The handle is then moved back to its initial
position with the catch o in the notch zero whereby the opening e¹ is brought opposite
to the supply pipe b and the plug e is again filled with liquid. Again if the handle f
be now moved to the extreme right so as to cause the catch o to engage the notch 6
the slot e will have been brought opposite the passage a', the whole contents of the
plug e will be drawn off and a corresponding record made by the registering
mechanism. In like manner if the handle f had been moved to bring the catch o
opposite either the notch 3 or 4 a corresponding quantity of liquid would have been
withdrawn and a corresponding record made.
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 :-
1. In a measuring and registering tap or valve the combination with a valve casing
which is provided with suitable supply and delivery pipes or passages and to which
the registering apparatus is secured, of a hollow plug provided with an inlet opening
and two or more slots placed at different levels whereby when the handle is operated
..and the valve opened a certain measured quantity of liquid is drawn off and the
withdrawal recorded substantially as herein set forth.
2. The combination of the valve casing a, the plug e provided with inlet and

page_text: discharge openings and a float valve for closing the tap against the atmosphere, and
the handle for its equivalent by which both the tap and the registering apparatus are
operated all substantially as herein set forth.
3. The general construction combination and arrangement of parts embodying my
improvements in measuring taps or valves substantially as and for the purposes herein
described with reference to the drawing annexed.
