PROVISIONAL SPECIFICATION.
An Improved Measuring and Draw-off Tap.
I, GUILFORD MOFFATT DUDLEY, 51 Middle Abbey Street, Dublin
Merchant, do hereby declare the nature of this invention to be as follows:-
The tap is made with plug and barrel at right angles with the stem, as in case of
an ordinary tap. A waterway or inlet runs the full length of the stem, and is
continued through the barrel to the plug, which is hollow in the centre to form
the measure. A port is bored in the plug communicating with the waterway or
inlet. A small airway is bored through the stem, barrel & plug, above the water-
way and parallel to it. The crown or inside top of the plug slants from the top
of the airway downwards towards the front of the plug. The inside bottom of
the plug being splayed at right angles with the splay or slant of the top. A port
is bored at the bottom of the plug at right angles with the water inlet port or
water way, which, when the plug is turned one quarter way round, comes opposite
an outlet port or delivery nose fixed on front of the barrel.. Auother port is bored
at the bottom of the plug at right angles with the other lower port, which comes
opposite the delivery nose when the plug is turned one quarter way further
round, that is, one halfway round from the starting point.
Another port is bored in the plug directly opposite and on a level with that port
which corresponds with the waterway or inlet, so as to communicate with the water-
way or inlet when the plug is turned one halfway round from the starting point.
A small air hole or vent is bored in the side of the barrel, communicating with the
air port in the plug when the plug is turned one quarterway round. A small angular
piece of metal tube is screwed into the air way at the extreme end of the stem,
having it's open end turned upwards. The stem of the tap is tapered towards the
end, and screwed, by means of which it is attached to a cask or other vessel.
When the plug is turned to its original position, that is, with the first mentioned
port and air way in the plug, communicating with the waterway or inlet and air
way in the stem and barrel, the liquid will flow into the inside of the plug, by
waterway in stem and barrel and corresponding port in the plug; the air escaping,
into the vessel to which the tap is attached, by the air port in the plug & air way
in the barrel & stem; the slanted crown of the plug allowing all the air to escape,
no matter at what angle the tap may be placed, and the small angular tube at end
of the stem assisting the passage of the air. When the plug is turned one quarter
way round, the first mentioned port at the bottom of the plug coming opposite and
communicating with the outlet or delivery nose, and the air port in the plug coming
opposite and communicating with the air hole in the side of the barrel, through
which the plug is vented, the contents of the plug will be discharged, the splayed
or slanted inside bottom of the plug allowing the full quantity of liquid contained
in the plug to flow off, no matter at what angle the tap may be placed. When the
plug is turned one quarterway further round, or one half way round from the
starting point, the second mentioned lower port in the plug coming opposite and
communicating with the outlet or delivery nose and the second mentioned upper
port in the plug coming opposite and communicating with the waterway or inlet,
the liquid will flow continuously.
Dated this 9th day of January 1896.

An Improved Measuring and Draw-off Tap.
I, GUILFORD MOFFATT DUDLEY of 51 Middle Abbey Street, Dublin
Merchant 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 :-
This invention has reference to a new or improved measuring and draught tap
whereby a given quantity of liquid may be conveniently and accurately measured
and delivered from a general source without the aid of a detached measurer and
whereby a continuous supply may also be delivered at pleasure.
The following description as read in connection with the accompanying drawings
will enable my said invention to be more readily understood and carried into
practice.
Fig. 1. is an elevation of my improved tap complete.
Fig. 2. is a cross vertical section of same.
Fig. 3. shows the plug detached in its first, or normal position.
Fig. 4. shows same turned a quarter revolution.
Fig. 5. shows same turned a half revolution.
On reference to Figs. 1. and 2 it will be perceived that my improved tap consists
so far as its exterior appearance is concerned of a barrel, a screwed stem, and a
plug, somewhat similar to an ordinary draught tap.
In my invention however the plug is hollow, thus constituting the means of
measuring liquid without the aid of a separate measurer as presently described.
A water way or inlet 1. runs the full length of the stem and opens into the plug
through a port 2, while the plug is in its normal or closed position as shewn in
Figs. 1, 2. and 3.
A small airway 3 is bored through the stem parallel to the inlet 1. and communi-
cates with the chamber in the plug by port 4.
The crown or inside top of the chamber inclines from left to right and the
bottom inclines in the opposite direction as shewn (Fig. 2).
A port 5 is formed in the base of the plug at right angles to the inlet port 2,
which when the plug is turned one quarter round (Fig. 4.) comes opposite the
outlet or delivery nose 6.
So far the action of my invention as a means of measuring a given quantity of
liquid is obvious.
Thus while the plug is in its normal condition (Figs. 1, 2 and 3) the liquid flows
from the source into the hollow plug, while simultaneously the air contained therein
escapes through the air way 3, the free end of which is provided with a nozzle 7,
turned upwards to facilitate the flight of air through the liquid in the source.
To deliver the measure of liquid it is only necessary to turn the plug one quarter
round which movement shuts off the supply while it brings the port 5 opposite the
outlet 6, whereupon the contents of the plug is discharged.
While in this position the air hole 4, in the plug comes opposite an air hole 8, in
the shell of the tap whereby the plug is filled with air as the liquid leaves, and the
plug is free to be restored to its normal position when it again automatically
becomes filled with liquid.
This movement may be repeated as often as required.
My invention is used as a continuous delivery or ordinary tap as follows:-
A second port 9 is formed at the base of the plug at right angles to the port 5
(Figs. 2, 3, 4 and 5) which comes opposite the outlet, when the plug is turned half
way round while simultaneously a port 10 (Figs. 2, 3 and 5) comes opposite the
supply inlet 1.

page_text: In this position that is when the plug is turned half way round-a clear anl.
uninterrupted passage is formed for the continuous flow of liquid.
Thus by the use of my invention a tap is produced capable of measuring liqui.l
in a convenient and accurate manner and also capable of being used as an ordinary-
tap, it being understood that the chamber in the plug may be of any capacity.
according to requirements.
A stud 11 (Figs. 4 and 5) is provided in the plug which plays in a recess formed.
half way round on the upper edge of the tap, and fixes the plug in its normal, and.
half revolution positions.
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
claim is
The use and application of a tap whereby a given quantity of liquid may be.
conveniently and accurately measured without the aid of a separate measurer and
which can also be used as an ordinary draught tap, constructed, arranged, and.
operating in the manner substantially as herein specified and set forth.
