Improvements connected with Beer Engines.
I, CHARLES HEDLEY HATTERSLEY of 25 Fitzwilliam Street, Swinton near Rotherham
in the County of York, Engineer do hereby declare the nature of my invention to
be as follows:-
My invention relates to the draw off Taps of "Beer Machine" the object being to
prevent the liquid sinking by gravitation in the pipes and thereby requiring several
strokes of the pump to be made before the supply can be obtained.
For this purpose the Taps are provided with a turn plug of usual construction but
it is very common (especially in busy times and from forgetfulness) to allow the
tap to remain open and any slackness of fit in the pump plunger the effect of
wear permits the liquid to sink down the pipes, which have to be refilled by the
pump before any liquid can be drawn.
I propose to dispense with the turnplug and to construct the body of the so-
called Tap with a check valve though which the liquid passes at each stroke of the
pump but which falls upon its seat automatically and thus prevents the admission of
air and supports the liquid in the pipe.
An opening with a removable screw cap above the valve permits easy access for
examination.

Improvements connected with Beer Engines.
I, CHARLES HEDLEY HATTERSLEY, of 25 Fitzwilliam Street, Swinton near Rotherham
in the County of York, Engineer do hereby declare the nature of this invention
and in what manner the same has to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to the draw off Taps of Beer Machines, the object being to
prevent the liquid in the pipes sinking back by gravitation and thereby necessitating
several strokes of the pump to be made before the supply required can be
obtained.
Hitherto the taps used for this purpose are what are known as plug taps, and
require turning by the hand to close them, and it is a common occurrence in busy
times especially, to forget to close the tap with the result that if the pump is at all

page_text: defective, the liquid sinks in the pipes which have to be refilled before any liquid
can be drawn off.
The drawings annexed clearly illustrate the nature of my invention, like letters
indicate like parts in either figure.
Fig. 1, is an elevation of an improved Tap.
Fig. 2, is a section of same, the valve and the closing screw being shown full.
In my improved tap I dispense with the plug and substitute a gravitation valve V,
which in its normal position rests upon the seating V S, through which the liquid
passes at each stroke of the pump which raises the valve V, and after the liquid has
passed, the valve falls back upon the seating by gravitation automatically.
It thus prevents the admission of air into the pipes and supports the liquid.
The opening above the valve, and through which the seating is machined, and the
valve placed in position, is closed by a screw cap C, preferably with a recess R, to
guide the valve, and also provided with a set screw SS, by which the valve can be
held upon the seating when required.
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. A tap for Beer Engines having a gravitation valve, acting automatically, and
constructed as hereinbefore described and shown.
2. In a Tap for Beer Engines the combination of a gravitation valve V, seating V S,
and a set screw S S, substantially as described and shown.
Dated the 7th day of July 1897.
