IN THE PROCESS OF BREWING, AND IN APPARATUS USED THEREIN.'
My Invention has for its object the prevention of the necessity of striking the hops
out of the copper after each boiling of the wort, thereby saving the expense of
elevators, and economising labour and fuel; and my Invention consists in adapting
and applying to the boiling copper a pipe having its discharge from the copper at a
higher point than the ordinary striking out pipe, and having combined with it a
suspended strainer, to which is supplied scrapers for the purpose of clearing the outer
surface of the strainer and preventing it from becoming choked, such scrapers being
worked as required from the outside of the copper. The said pipe be fitted to
act as a syphon or otherwise, so as not to interfere with any rousing or stirring
machinery inside the copper.
The strainer may be made of perforated or slotted sheets of copper or of wire, and
suspended from the stays of the copper; and the scrapers may be hinged or jointed,
as required, in order to facilitate their being worked over the surface of the strainer
from outside the copper.
The ordinary pipe at the bottom of the copper is retained for the purpose of
striking out hops and wort when the whole process of boiling has been completed.
By means of the arrangement of apparatus above referred to, the whole process of

page_text: boiling can be completed before the hops and wort are struck out, thereby obviating
the necessity for striking out the same after each boiling, in the manner hitherto
practised.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Cairns Wilson in the Great Seal Patent Office on the 18th June
1878.
JOHN CAIRNS WILSON, of the Ardee Street Brewery, Dublin. " IMPROVEMENTS IN
THE PROCESS OF BREWING, AND IN APPARATUS USED THEREIN."
My Invention of "Improvements in the Process of Brewing, and in Apparatus
Used therein," has for its object the prevention of the necessity of striking the
hops out of the copper after each boiling of the wort, thereby saving the expense of
clevators, and economizing labor and fuel; and my Invention consists in adapting
and applying to the boiling copper a pipe, having its discharge from the copper at a
higher point than the ordinary striking out pipe, and having combined with it a
suspended strainer, to which is applied scrapers for the purpose of clearing the outer
surface of the strainer, and preventing it from becoming choked, such scrapers being
worked as required from the outside of the copper. The said pipe may be fitted to
act as a syphon or otherwise, so as not to interfere with any rousing or stirring
machinery inside the copper.
The strainer may be made of perforated or slotted sheets of copper or of wire,
and suspended from the stays of the copper; and the scrapers may be hinged or
jointed, as required, in order to facilitate their being worked over the surface of the
strainer from outside the copper.
The ordinary pipe at the bottom is retained for the purpose of striking out hops
and wort when the whole process of boiling has been completed.
By means of the arrangement of apparatus above referred to, the whole process
of boiling can be completed before the hops and wort are struck out, thereby
obviating the necessity for striking out the same after each boiling, in the manner
hitherto practised.
Having thus stated the nature of the said Invention, I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying Drawings, in which is represented some of the parts of apparatus
above referred to.

page_text: of perforated or slotted sheets of copper or of wire, and is suspended from the stays
E, E, as shewn in any other suitable manner; F, F, are scrapers, which are jointed
at G, G, at each end of a bar H, to which is fixed a vertical rod I extending
upwards, so as to admit of its being worked from outside the copper.
The scrapers F, F, are furnished with chains K, K, at the bottom, and can be
worked over the surface of the strainer D, as required, by means of the vertical rod
I for the purpose of clearing the outside of the strainer, and preventing it from
becoming choked.
L is a hole or opening in the top of the strainer for the insertion of a pipe, having
its discharge from the copper at a higher point than the ordinary striking out pipe,
which is not shewn in the Drawing, but is intended to be inserted in the lower part
of the copper, as usual.
The pipe fitted in the opening L may be adapted to act as a syphon or otherwise,
as preferred.
By means of the strainer D, combined with the discharge pipe inserted in the
opening L, the necessity for striking the hops out of the copper after each boiling
of the wort will be prevented, the said strainer having its outer surface cleared,
as required, by working the scrapers F, F, by means of the rod I, as described.
Having thus described the nature of the said Invention, and in what manner the
same is to be performed, I hereby declare that what I claim as of my Invention
is, the adaptation and application to the boiling copper of a pipe and strainer with
scrapers for the purpose of preventing the necessity of striking the hops out of the
copper after each boiling of the wort, as herein-before described.
In witness whereof, I, the said John Cairns Wilson, have hereunto set my
hand and seal, this Fourteenth day of June, in the year of our Lord One
thousand eight hundred and seventy-eight.
Witness,
E. W. THOMPSON,
Newry,
Brewer.
