Improvements in Beer Engines, and in Connections thereto.
We, GEORGE WATSON, of Peak Hill, in the Colony of New South Wales,
Plumber, and ALFRED JAMES FOLEY, of Club House Hotel, Peak Hill, afore-
said, Hotelkeeper, do hereby declare the nature of this invention and the manner
in which the same is to be used to be particularly described in and by the following
statement:-
The object of this invention is the improvement of pumps for drawing beer or
other liquids and of connections thereto in order together with other advantages to
enable the beer, or other liquids to be drawn in a pure and cool state and to
prevent the liability of liquid being frozen in the pumps or connections in frosty
weather, or to prevent liquid standing in the connections or pumps at any time
when such a location of liquid is not desired.
The invention is illustrated in the accompanying drawings in which Figure 1
shows a side elevation and Figure 2 a vertical central section through similar parts
to those shown in Figure 1.
A is the pump cylinder preferably having a glass inner lining G and an outer
jacket forming an annular chamber C. B is the pump outlet, C2 is a removable
lid closing the inlet of C and C a removable screw plug closing the outlet of C.
Any cooling or insulating medium may thus be introduced into chamber C.
This pump is improved by providing on the upper side of the suction valve H or
(as shown on drawing) on the under side of the bucket valve J, a projecting spindle K
in such a position that if when the bucket valve is located at the lowest point
of its stroke, the suction valve is then raised, the bucket valve will also be lifted
up, thus allowing the liquid above both valves to escape by gravity through the
connecting pipes beneath. To effect the raising of H a lifter rod F is provided
affixed to an exteriorly accessible handle D and having its interior free end bent to
form a finger or cam the end of which is adapted when a half turn is given to D
to meet the under surface of a collar or projection from the spindle on the
under side of valve H, and thereby to raise H for the purposes set forth. There
may be fitted to the pump cylinder base a hollow plug as E into which the valve
raising device is screwed. I is a union, ii are nuts, L a light metal tube,
enclosing the glass tube g, and M is a diminishing socket, connecting I and L, being
soldered to the latter usually. N is a cork ring, and O a rubber ring each used
as a packing between the glass and metal tubes and L. Between the tubes L
and a heat insulating material is to be packed such as pumice stone powder
or fine sawdust, the rings ON keeping the said material in place and also being
so arranged as to prevent the liquid from coming into contact with the metal L
or with the insulating material, through the joints P between the glass tubes.
The jacketted glass pipe connections from the pump C to the source of liquid
supply embrace a device for enabling the pipes to be connected with auy one of
a number of barrels without wasting liquid whilst shifting the connection from
one barrel to another. This device includes two parts which are used as a
combination viz., a pivoted head joint and a stop cock foot.
In the head joint there are two members, a plug Q at the lowest end of the
fixed portion of the pipes y, L, said plug having if necessary an outer end support R
the upper end of which may be secured to the cellar roofing or in any other suitable
way. Qis a sleeve fitting closely round Q and having at its base a sleeve Q to
which the upper end of the line of swingable tubes L' is soldered or secured. The

page_text: parts of Q and Q are so arranged that they remain in communication with one
another at any angle to which the depending line of pipes L is swung and while
a connection with a barrel, or other source of liquid supplied is not required the
pipes L may be tilted aside and fastened up in order to be out of the way. At the
foot of the tubing which forms a swinging arm as aforesaid, is a plug valve having
a plug S seated in a sleeve T and turned by a handle U. The plug is provided
with a collar V at near its lowermost end by which means the part W may be
permanently secured in engagement with S. The part W consists in part of an
ordinary screw threaded nut, the thread extending only partly through the metal,
and being supplemented at X by a cylindrical surface and at Y by an annular
flange having a central opening of less diameter than the collar V. When the end
of any connecting pipe leading from a barrel or the like is now screwed to W
it will be found that there will be no danger of overscrewing and consequent
straining of the pipes, whilst the handle U can be easily turned when desired to
close the plug S to swing the part extending from Q to W to any other angle
in the same vertical plane. Z is a nut for keeping the handle or key in place.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination of a valve J, spindle K, and valve H substantially as and
for the purposes set forth.
2. The combination of valve J, spindle K, valve H, collar or projection h, and
lifter rod F having cam fand handle D substantially as and for the purposes set
forth.
3. In combination the jointed parts L, Q, Q, Q the movable piping Li
depending therefrom, the stop cock parts S, T, U at the lower end of the piping L'
said part S having a shoulder V, and the nut W having a cylindrical surface X
and the shoulder Y all substantially as and for the purposes set forth.
4. The general combination and arrangement of parts of the beer engine A aud
the connections thereto as illustrated and as hereinbefore described.
