PROVISIONAL SPECIFICATION.
Improvements in or connected with Beer Engine Mechanism.
We, THOMAS JACKS, of Gower Street, Saint George's, Salop, Plumber, and
JAMES FORREST, of Moor Street, Ormskirk, Lancashire, Shopkeeper, do hereby
declare the nature of this our said invention to be as follows:-
This invention relates to improvements in or connected with barrel taps and
beer engines pumps and its object is to provide an attachable and removable valve
mechanism between the suction pipe of the pump and the tap of the barrel.
It is frequently found that a small flaw or crack or hole in the suction pipe
occurs, but is sufficient to admit air when the pumping takes place, although
perhaps too small to permit of the leakage of the ale or stout or other liquid under
treatment. This makes it very difficult to detect its position and not only so, but
the air thereby finds its way back into the barrel and causes frothing, and even
while in the pipe destroys the proper vacuum of the pump. In order to overcome
these difficulties we provide a non return valve suitably mounted in a valve box
which may be readily secured to the nose of the barrel tap, while to the other end
of the said box the usual union of the suction pipe may be secured, as heretofore
it has been secured to the tap.
This valve is kept up to its seat by a spring of suitable strength. The position
of this valve box may be varied as that it may be near to or some distance from
the tap, but to be fixed upon the tap is the best position.
Hence this valve is always closed except when under the influence of the pull
of the pump, and consequently no air, nor the contents of the pipe are allowed to
re-enter the barrel.

COMPLETE SPECIFICATION.
Improvements in or connected with Beer Engine Mechanism.
We, THOMAS JACKS, of Gower Street, Saint George's, Salop, Plumber, and
JAMES FORREST, of Moor Street, Ormskirk, Lancashire, Shopkeeper, 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 relates to improvements in or connected with barrel taps and
beer engines pumps and its object is to provide an attachable and removable valve
mechanism between the suction pipe of the pump and the tap of the barrel.

page_text: It is frequently found that a small flaw or crack or hole in the suction pipe
occurs, but is sufficient to admit air when the pumping takes place, although
perhaps too small to permit of the leakage of the ale or stout or other liquid under
treatment. This makes it very difficult to detect its position and not only so, but
the air thereby finds its way back into the barrel and causes frothing, and even
while in the pipe destroys 'the proper vacuum of the pump. In order to overcome
these difficulties we have made this our invention, and that we may explain it more
clearly we have appended hereunto an illustrative drawing upon which are figures
and numbers of reference.
Fig. 1, is a general sectional view of this our invention.
Fig. 2, is a detailed end view of the moveable (spring) washer employed in the
valve.
Fig. 3, is a detailed end view of the fixed (spring) washer employed in the valve.
In carrying out this our invention, we provide a non-return valve 5, suitably
mounted in a valve box 6, which may be readily secured to the nose 7, of the
barrel tap 8, while to the other end of the said box the usual union 9, of the suction
pipe 10, may be secured, as heretofore it has been secured to the tap 8.
This valve 5, is kept up to its seat by a spring 11, of suitable strength.
At the rear side of the valve is a washer or plate 12, which is free to slide within
the box 6, and at 13, is a second plate or washer which is screw threaded within
the said box. Between these, two washers is the spring 11, which always tends to
seat the valve. By reason of the shoulder at 14, upon the spindle of the valve
the opening of the valve is limited in its extent, but which by means of the
washer 13, may be adjustably increased or diminished.
The position of this valve box may be varied as that it may be near to or some
distance from the tap but to be fixed upon the tap appears to be the best position.
Hence this valve is always closed except when under the influence of the pull
of the pump, and consequently no air, nor the contents of the pipe are allowed
to re-enter the barrel.
Having now particularly described and ascertained the nature of this our
said invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. The combination with, and the interposing between, a barrel tap and its pump
for drawing off the liquid, of a valve device substantially as that herein described
and shown upon the drawings.
2. The valve device as herein described and shown upon the drawings as an
attachment to or combination with the barrel tap, as set forth and shown.
