WILLIAM SPENCER (Contractor) & JOSEPH JONES Brewer of West Derby in the
County of Lancashire do hereby declare the nature of their invention to be as
follows:-
The first part of our Invention consists in the adoption of a grated or perforated
vessel of round or any other convenient shape and made by preference of cast iron
or other suitable material-the perforations are by preference longitudinal slits
formed in tiers and having at the bottom of each tier a ledge with serrated or
toothed edge.
This vessel is provided if required with a perforated bottom which is supported on
radial bars let into the sides and is made in sections for convenience of removal and
cleaning, and is placed on a shallow vessel of suitable form which receives the liquor
passing through the contents of the perforated vessel.
The second part of our Invention consists in the application of what is technically
Sparger" which is placed over the perforated vessel so as to command
known as a
the entire surface.
The operation and function of the above Invention is to obtain perfect aeration of
the wort or liquor discharged into it from the Brewing Copper while on its passage
to the cooler or refrigerator, the hops and solid matter being intercepted within the
above named perforated vessel while the liquor drains through the bottom and the
vertical slits in the sides, the latter passing over each ledge and being spread in a
thin stream by the action of the serrated edge over which it falls, the upper ledges
being placed in such position as to cause the upper streams to fall clear of the
lower streams and so facilitate the completo aeration of the mass. When the whole or
part of the contents of the Copper has been discharged and drained off, liquor of the
required temperature is turned into the Sparger which by its action thoroughly
saturates the whole mass of hops or other material remaining in the perforated vessel
and washes the remaining saccharine matter out of them.

Improvements in the Treatment of Brewers' Worts.
We, WILLIAM SPENCER of 165 Prescot Road Knotty Ash, Liverpool, Contractor,
and JOSEPH JONES of the Brewery, Knotty Ash, near Liverpool, Brewer, 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
The object of this Invention is to aerate and oxygenate the Worts when issuing
from the Brewing Copper, and for this purpose a cast iron or other metal Cage or
Receiver is placed in any convenient position on the Cooler or Wort Receiver. This
Cage has fine slits over its entire surface, and rims at intervals, these rims having
serrated edges to spread the worts over as large a space as possible so that the
atmosphere has full play over the greatest surface obtainable.
When the worts have drained through the slits a stream of boiling water is
discharged over the Hops remaining inside the cage, an ordinary revolving Sparger
being used for this purpose. The following is a description of the Drawing which
accompanies this Specification, A is the bottom of the Cage, which is made in
Segments and perforated with fine slits or holes. B is the body of the Cage, having
vertical slits and ribs or rims with serrations on the edges b. b. C is the Cooler or
Wort Receiver into which the Worts drain. D. is the Sparger through which the
water is discharged over the drained Hops remaining in the Cage.
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:-
1st. The arrangement of Draining Cage as described and shewn in drawing for the
more perfect aeration and oxygenation of Worts as discharged from Boiling Coppers
and other Vessels.
2nd. The arrangement for sparging the drained Hops as described.
