PROVISIONAL SPECIFICATION.
Improvements in Beer Extractors.
I, THOMAS HAYLOR HOWARD of Roupell Arms, Lower Woolwich Road, Charlton,
in the County of Kent, Manager do hereby declare the nature of this invention to be
as follows:-
The invention has for its object improvements in beer extractors and relates to the
combination therewith of means for preventing the return of the beer from the
extractor into the cask or barrel and for facilitating the draft therefrom.
For this purpose I fit the extractor just above the strainer, with a self acting valve,
which whilst freely permitting the upward flow of the beer from the cask or barrel
will prevent the return thereof into the barrel, thereby ensuring a constant supply of
beer to the engine and preventing the beer in the cask or barrel from being disturbed
by the return of the beer from the extractor.
The strainer usually employed is merely a perforated portion of the extractor tube.
immediately above the rest or support at the bottom thereof, this frequently becomes
clogged with the hops in the cask or barrel, now in order to facilitate the draft I
surround the above mentioned strainer with a second perforated or reticulate strainer
of conical or other form which when the suction ceases will allow the hops to fall
away therefrom and will therefore be less liable to become choked than the strainer
hitherto in use whilst it will entirely prevent the access of hops to the inner strainer.
If desired the outer strainer may be of cylindrical form.

COMPLETE SPECIFICATION.
Improvements in Beer Extractors.
I, THOMAS HAYLOR HOWARD of Roupell Arms, Lower Woolwich Road Charlton in
the County of Kent Manager 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 for its object improvements in beer extractors and relates to the
combination therewith of means for preventing the return of the beer from the
extractor into the cask or barrel and for facilitating the draft therefrom.
For this purpose I fit the extractor just above the strainer with a self acting valve,
which whilst freely permitting the upward flow of the beer from the cask or barrel
will prevent the return thereof into the barrel thereby ensuring a constant supply of
beer to the engine and preventing the beer in the cask or barrel from being disturbed
by the return of the beer from the extractor.
.
The strainer usually employed is merely a perforated portion of the extractor tube
immediately above the rest or support at the bottom thereof this frequently becomes
clogged with the hops in the cask or barrel, now, in order to facilitate the draft I
surround the above mentioned strainer with a second perforated or reticulate strainer
of conical or other form which when the suction ceases will allow the hops to fall
away therefrom and will therefore be less liable to become choked than the strainer
hitherto in use whilst it will entirely. prevent the access of hops to the inner strainer.
If desired the outer strainer may be of cylindrical form.

page_text: In order that my invention may be properly understood and readily carried into
effect I have appended hereto a sheet of drawings in which,
Fig. 1. is an example of a beer extractor constructed according to my invention in
vertical section.
Fig. 2. is an elevation of the same.
Fig. 3. is a plan and
Fig. 4. a section through line a. b. Fig. 1.
To the extractor pipe, A, attached to the beer engine is secured in any suitable
manner the valve chamber, B, preferably constructed in two parts enclosing a ball or
other valve, C, which when in its normal position rests upon the seat, D, formed in the
upper part of the lower portion of the said chamber, B. The upper portion of the
said chamber, B, is provided with four projections or stops (more or less), E, which
form in the said chamber four passages (more or less), F, through which the beer
passes on its way to the engine. These projections E prevent the ball valve, C, rising
too high and cutting off the supply from the barrel or other vessel.
Beneath the valve, C, is secured the strainer, G, provided with perforations, H, into
the lower portion of which is screwed or otherwise secured the rest, J, which is made
adjustable according to the contents of the cask or barrel. To the strainer, G, is
secured a second strainer, K, made adjustable and perforated similar to the inner
strainer, and is in preference conical in shape. The strainer G is screwed or otherwise
secured to the rest, J.
The lower part of the chamber B is formed hexagonal square or other shape to
receive the jaws of a spanner or wrench when the ball valve, U, requires regulating or
for cleansing purposes.
It will thus be seen upon reference to the drawings and foregoing description that
the suction caused by the beer engine raises the ball valve, C, off its seat, D, thus
allowing the beer or other liquid to pass on to the beer engine through the passages, F,
but so soon as the suction ceases the ball valve, C, will drop into its seat and prevent
the return of the liquid to the barrel or other vessel. At the same time the strainer, K,
is formed of such a shape (conical) that the hops or other sediment in the barrel will
be drawn by suction against the outside thereof and will fall back into the barrel so
soon as the suction caused by the engine ceases thus preventing the access of hops or
other' sediment to the inner strainer, G.
I wish it to be understood that I do not confine myself to the exact shape or form
of the various parts as other forms of valves and strainers may be used with equally
good results.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
claim is
The combination with a beer extractor of the valve chamber, B. projections or
stops, E, valve, C, strainers G and, K, and rest J or their or either of their equivalents
substantially as herein described and shewn in the accompanying drawings.
