I, COLIN HENRY MOON, of Osborne House, Moseley, near the City of Birmingham,
Manufacturer, 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 consists of improvements in measuring taps for spirits, oil, and
other liquids, my object being to construct a simple and convenient tap having a
measuring chamber that can be very readily filled with the required quantity of
liquid, such liquid being subsequently discharged with equal facility into the
desired receptacle.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to,-
Figure 1 is a sectional side elevation and Figure 2 an end elevation of a
measuring tap constructed in accordance with my invention.
The same reference letters in the two views indicate the same parts.
In the application of my invention I form the conical metal body A of the tap
either by casting in the ordinary manner or from sheet metal by stamping or like
processes. With such body I form or attach a hollow stem B by which the tap is
attached to the cask or other vessel C and through which the liquid flows into the
measuring chamber working within the tap body. I also form with or attach to the
tap body a spout or nozzle D for the discharge of the liquid from the measuring
chamber.
The measuring chamber consists of a conical and hollow plug E fitting within the
tap body A, after the manner of an ordinary tap or cock plug. The plug is formed
either by casting in the ordinary manner, or by stamping or like processes from
sheet metal. The larger end of the plug or chamber, or the end adjacent to the
cask or other vessel, is closed, whilst on the projecting stem from the smaller end,
which is also closed, I attach a suitable operating handle as F.
I provide two oppositely disposed vents or apertures as e and e¹ in the cylindrical
wall of the measuring chamber E, the aperture e being for the admission and
discharge of the liquid, whilst the aperture e¹ is arranged to admit the air necessary
for the rapid discharge of the contents of the chamber, when it is brought into
position immediately beneath the aperture a in the tap body.
When the aperture e of the measuring chamber E is brought by movement of the
operating handle F into the position immediately beneath the hollow stem B as
illustrated at Figure 1, the liquid will flow from the cask or other vessel C into the
measuring chamber E, whilst the air which is displaced from the chamber by the
incoming liquid will pass along the hollow stem B in the opposite direction to
the flow of the liquid, and will be discharged into the cask or other vessel through
the aperture 6 provided for that purpose in the upper side of the portion B₁ of the
stem projecting within such vessel. Thus simultaneously with the flow of the liquid
through the stem B in the direction shown by the arrow 1 at Figure 1, the displaced air
from the chamber E will escape freely through the aperture b as indicated by the
arrow 2 at Figure 1 and passing through the liquid to the upper part of the
en

page_text: vessel C will offer no obstruction to the flow of the liquid through the mouth of
the stem.
By such a construction and arrangement of parts I am enabled to fill the
measuring chamber very rapidly, and after such filling, and on turning the chamber
through a half circle in the direction indicated by the arrow at Figure 2, the
aperture e is brought into position immediately over the spout or nozzle D,
simultaneously with the movement of the air inlet aperture e¹ into a position
immediately under the aperture a in the tap body A. The measured quantity of
liquid will then be quickly discharged from the chamber into the required receptacle
placed beneath the spout D.
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 1
claim is :-
1. In measuring taps, means for effecting the rapid discharge of the air on its
displacement from the measuring chamber without obstructing the flow of the
incoming liquid, substantially as described.
2. A liquid measuring tap constructed and arranged substantially as and for the
purposes described and as illustrated.
