"IMPROVEMENTS IN RAISING FORCING AËRATING COOLING AND ROUSING BEER AND
OTHER LIQUIDS AND IN APPARATUS THEREFOR PART OF WHICH INVENTION IS
APPLICABLE ALSO FOR HOP OR OTHER SPARGING."

This Invention has for its object an improved mode of raising, forcing aërating
cooling and rousing beer oils or other liquids and also a new method of working the
ordinary rousing propellor by air acting upon beer or other liquids for aärating
rousing and cooling, making it at the same time give an effect of aërating rousing,
cooling forcing and expelling gases from such beer or other liquids: also the
construction of a reciprocating tube traversed by suitable reversing mechanism
along the top or sides of squares, vats tuns hop-backs or other vessels for aërating
pumping cooling and distributing beer or other liquids and to act as a sparger in
hop-backs and other vessels.
Firstly. We propose to place in the ordinary squares, vats, tuns, or boilers, a
copper or other tube, the bottom of which is enlarged and perforated with holes,
and the top forming a bend of any length required. A short distance from the
bottom of the tube, a pipe is inserted turning upwards inside the tube, or at the top
of the bend on the tube a pipe is fixed passing down inside the tube to a corresponding
depth to the pipe inserted in the side, and is also turned up at the bottom.
The said small pipe or pipes are connected with an air pump, accumulator or
reservoir of air. Upon the said air pump, accumulator or reservoir being set in
motion or opened to the air supply pipe, the beer or other liquid in the squares, vats,
tuns or boilers is forced up the tube and through the large bend which may be
standing 1, 2, 3 or more feet from the surface of the beer or other liquid and a sieve
or perforated frame may be placed under the bend for the beer or other liquid to be
discharged or fall in the form of spray into the square, vat, tun or boiler, so being
continually worked, circulated aërated and roused while the air pump accumulator
or reservoir is in motion, or opened to the air supply pipe.
Socondly. Another form of tube may be placed in the square, vat, tun or boiler,

page_text: similar in all respects to the above with the exception of the top which is made
with a fountain head instead of the bend and the beer or other liquid is forced
through the head and falls in the form of spray all round the enlarged fountain
head into a perforated receiver or direct into the square vat, tun or boiler
Thirdly The next part of our invention has for its object improved means of
working the ordinary one two three or more- bladed or winged propellors or
rousers. The upright shaft of the propellor or rouser is preferably made of tubing
(although it may be made in any other way), the bottom of which is solid, working
in a footstep and the top of the tube being carried by an ordinary or other bracket.
At the top of the tube is fitted a swivel union or stuffing-box, to which is connected
an air supply pipe and at a convenient distance on the tube is fixed the propellor
or rouser. The back of each blade or wing has a hole or a bent pipe having its
communication with the inside of the tube an air pump, accumulator or reservoir
being set in motion or opened to the swivel union or stuffing box on the top of the
tube by a suitable pipe, forces the air down the tube through the holes or bent
pipes at the back of the blades or wings, thus forcing them round and rousing the
beer or other liquid and at the same time cooling and aörating.
Fourthly. The last part of our invention relates to a novel reciprocating tube-
aërator cooler and distributor which is also applicable for hop or other sparging.
On the top or sides of the square vat or-tun-or-hop-back-or-other vessel_we_fix_
rails or rods and upon the same mount one or more grooved pulleys-on-each end of
a distributing or sparging tube. The tube is made to revolve or is fixed to the
spindle which carries the grooved pulleys at each end. An endless chain or other
suitable incans is employed to work the tube from end to end of the square hop
back or other vessel. The chain is fixed to the traversing tube spindle and passes
round a guide pulley at one end and a chain pulley carrying a toothed wheel-at-the-
other end. The said guide and chain pullies revolve on suitable studs fixed on the
square, hop back or other vessel. On the chain pulley end and fitted to suitable
brackets a counter shaft with-fast or-fast-and-loose-pulleys is arranged carrying_a
toothed wheel fixed to the shaft and a hanging quadrant bracket is suspended by
the counter shaft, carrying two pinions gearing together and running loose on studs.
One of the pinions is always in gear with the toothed wheel on the counter shaft
and either the one or the other with the toothed wheel on the chain wheel shaft.
By this means the chain is driven and the tube traversed along the square hop
back or other vessel.
A latch rod is fitted to the quadrant carrying the pinions and suitable tappets
are arranged on the traversing spindle or tube to operate the latch rod for
reversing.
The spindle of the tube is made hollow to receive the supply pipe from the air or
beer pump for aürating rousing and cooling or the water (or other) pipe for
sparging for hop backs or other vessels.
It is obvious that our invention may be used with a gas (such as carbonic acid
or other suitable gas) instead of or with air, and that the mere mechanical details
may be varied without departing from the principle thereof.
