Improvements connected with Beer Engines or Pumps.
We, RALPH EDWARD LANE, of 1 High Street, Peckham, Pewterer, and
GEORGE EDWARD LANE, of 6 Hansler Road, Lordship Lane, East Dulwich,
Brass Finisher, both in the County of Surrey, do hereby declare the nature of this
invention to be as follows:—
Our invention relates to beer engines or pumps and consists in arranging a
check-valve between the barrel from which the beer is being drawn and the pump
for preventing beer which may have been drawn into the pipes from returning to
the barrel.
In practice this check-valve is placed close to the barrel and is provided at one
end with a union coupling by means of which it may be readily attached and
removed.

COMPLETE SPECIFICATION.
Improvements connected with Beer Engines or Pumps.
We, RALPH EDWARD LANE, of 1, High Street, Peckham, Pewterer, and
GEORGE EDWARD LANE, of 6, Hansler Road, Lordship Lane, East Dulwich,
Brass Finisher, both in the County of Surrey, 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 :-
Our invention relates to beer engines or pumps and consists in arranging a
check-valve between the barrel from which the beer is being drawn and the pump
for preventing beer which may have been drawn into the pipes from returning to
the barrel.
In practice this check-valve is placed close to the barrel and is advantageously
provided with a union coupling by means of which it may be readily attached and
removed, or it may be arranged in a casing integral with the beer tap.
In the accompanying drawings,-
Figure 1 is a central vertical section; and,
Figure 2 is a plan of a suitable arrangement of check-valve, for use in connection
with beer engines or pumps, according to our invention.
Figure 3 is an elevation shewing the check-valve applied to the tap of a beer
barrel intended to be connected to a beer engine or pump:
Figure 4 is a sectional elevation of a beer tap having the check-valve arranged
in a casing integral with the said tap.
Similar letters in all the figures indicate similar parts.
a is the casing of the check-valve which we arrange between the barrel b,
Figure 3, from which the beer is being drawn and the pump (not shewn in the
drawing); c, Figures 1 and 2, is the valve proper working in the chamber d of the
casing a, the upper part e of which is detachable to allow the valve to be inspected,
and ff are the nozzles of the valve adapted to be connected respectively to the
pipe leading to the pump by means of the union couplings i and j and to the
tap g (see Figure 3) of the barrel b, but when the valve casing a is made integral

page_text: with the tap 9, as shewn in Figure 4, the nozzle f and its coupling are not
required.
The arrows indicate the direction in which the beer flows when the pump is
actuated, the valve c then opening under the pressure of the liquid. Directly,
however, the pump ceases to act, the backward pressure of the liquid in the pipe h
will close the valve e and prevent the return of the liquid into the barrel b.
с
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The use in combination with a beer engine or pump of a check-valve placed
between the receiver containing the liquid to be drawn off and the engine or pump
employed for drawing the liquid from such receiver, substantially as, and for the
purpose, herein before described and as illustrated in the accompanying drawings.
