Improvements in connection with Vessels for Drawing off, Measuring,
or Containing Liquids.
I, FREDERICK HUGHES, of 20, Paget Road, West Dulwich, London, 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 improvements in connection with vessels for drawing off
measuring or containing liquids and it is more particularly intended for use
when dealing with liquids such as black beers which "froth" when run or
poured into vessels or from one vessel to another. This frothing is very incon-
venient and causes great loss of time in correctly measuring the quantity of liquid
drawn off or poured into the vessel which is to receive it or from which it is to
be used. The object of my invention is to prevent this " frothing" and in order
to do this I cause or allow the liquid to flow into the measure or other vessel at
or near its bottom instead of at the mouth as is donc at present. In order to
more clearly show the nature of my invention I make reference to the accompanying
drawing which shows a vertical section of an arrangement whereby the liquid is
first run into a measuring funnel and from thence into a second vessel." a is
the measuring funnel into which the liquid is allowed to run by the pipe 6 or 6¹
(shown in dotted lines). The entry of the liquid into a takes place at or near
the bottom of a and the supply is regulated by the tap or stop cock cor c¹.
The liquid rises in a without any "froth" or "head" and can be allowed to
run into the second vessel d by the pipe e. In passing the liquid from e to d
provision is made by a pipe or channel f (not reaching to the bottom of d)
for the liquid to flow into near its bottom, thus obviating any frothing in this
second vessel. In cases where the vessel is to be removed for use it would be
provided with means for disconnecting it from the pipe e. Instead of having the
tube or channel f the liquid may enter d directly by a pipe e near its bottom
at as g and a tap can be provided as at h for cutting off the supply and means
may be provided for disconnecting d from e.
The vessel d need not be of special make for use with my invention. That is
to say the pipe or channel f is not absolutely necessary. All that is needed to
prevent the formation of froth in the vessel a is sufficient length of the pipe e¹
or of the nozzle of the draw off tap to enable them to be inserted deeply into a so
as to allow the liquid to enter d near its bottom.
It being impossible to show every method for putting my invention into practice
I do not confine myself to precisely what is shown in the accompanying drawing.
For instance in some cases the receiving vessel can have double walls the bottom
edge of the inner wall being above the bottom of the outer vessel so leaving a
space between them. The liquid would be allowed to enter at the top of the space
between the two walls and to flow into the vessel through the space between the
bottom of the outer vessel and the bottom edge of the inner wall.

page_text: 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. The method of preventing the "frothing" of liquids run or poured into
measuring or other vessels, the said method consisting essentially in permitting
the liquid to enter at or near the bottom of the said measuring or other vessels,
the whole substantially as described in the above, specification and exemplified
in the accompanying drawing.
2. For preventing frothing" of liquids run or poured into the measuring or
other vessels the provision of an inlet for the liquid at or near the bottom of
the said measuring or other vessels substantially as described in the above
specification and exemplified in the accompanying drawing.
3. For preventing frothing" of liquids run or poured into measuring or
other vessels the provision of a pipe channel or inner wall not reaching to the
bottom of the said measuring or other vessels, the liquid being allowed to enter
at the top of the said pipe channel or of the space between the upper ends of
the inner wall and the vessel and to flow into the vessel by way of the space
between the bottom of the pipe channel or inner wall and the bottom of the
measuring or other vessels, the whole substantially as described in the above
specification and exemplified in the accompanying drawing.
