Year: 1878

page_text: LETTERS PATENT to John Hodson, of 3, The Terrace, Clapham Common, in
the County of Surrey, Brewer, for the Invention of "IMPROVEMENTS IN THE
TREATMENT OF HOPS AND BEER, AND IN APPARATUS EMPLOYED THEREFOR."
Sealed the 2nd April 1878, and dated the 30th January 1878,
PROVISIONAL SPECIFICATION left by the said John Hodson at the Office
of the Commissioners of Patents on the 30th January 1878.

Brewer. "IMPROVEMENTS IN THE TREATMENT OF HOPS AND BEER, AND
APPARATUS EMPLOYED THEREFOR."
IN
The improvements in the treatment consist in first extracting from hops their
properties readily soluble in a cold menstruuni, and in afterwards exhausting the
remaining constituents by boiling the said hops in the ordinary way.
The improvements in the apparatus consist in the construction and use of one or
more extractors or filters fitted with doors or openings, and each furnished with
one or more perforated moveable or fixed trays, or equivalents therefor, for holding
hops. Also in fitting or supporting such trays at convenient distances apart in
one or a series of suitable chambers or receptacles furnished with suitable doors,
apertures, and inlet and outlet pipes, the chambers being made deeper than the
depth of the hops they are intended to hold, so as to afford space for their swelling
up when the beer is passed over or through them.
24
The improvements may be performed by making the apparatus of metal or wood,
or of metal and wood combined, or of other convenient material, and may be carried
out by fitting the trays in their chambers about 12 inches apart, and placing on
each tray a layer of dry hops, about six inches deep, the total quantity of hops
necessary being about half the quantity of hops that would be ordinarily used for
hopping down the same quantity of beer in the cask.
In carrying out my said Invention, I pass or filter beer before, during, or after
fermentation through a layer or stratum of hops placed in the improved or other

page_text: filter, as herein-before described, into a racking back or other suitable vessel of
sufficient size to receive the whole quantity of beer operated upon, after which the
whole or any desired portion of the saturated hops is pressed to remove the beer
therefrom, and also washed or otherwise treated, and the hops can afterwards be
used in the copper.
By the foregoing treatment, the essential oils of the hop, which it is well known
volatilize upon boiling, are preserved, and the desired aroma and flavour are imme-
diately imparted to the beer, which at present can only be obtained after the beer
has been hopped down and shived for some time.
The beer is also clarified and purified by the removal of the feculent and yeasty
particles.
The objection to the large quantity of dry hops so often used in the carriage
casks is overcome.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Hodson in the Great Seal Patent Office on the 27th July

The improvements in the treatment consist in first extracting from hops their
properties readily soluble in and by means of a cold or alcoholic menstruum, and
in afterwards exhausting the remaining constituents by boiling the said hops in the
ordinary way.
The improvements in the apparatus consist in the construction and use of one
or more extractors or filters fitted with doors or openings, and each furnished with
one or more perforated moveable or fixed trays, or equivalents therefor, for holding
hops. Also in fitting or supporting such trays at convenient distances apart in
one or a series of suitable chambers or receptacles furnished with suitable doors,
apertures, and inlet and outlet pipes, the chambers being made deeper than the
depth of the hops they are intended to hold, so as to afford space for their swelling
up when the beer is passed over or through them.
The improvements may be performed by making the apparatus of metal or wood,
or of metal and wood combined, or of other convenient material, and may be carried
out by fitting the trays in their chambers about 12 inches apart, and placing on
each tray a layer of dry hops about six inches deep, the total quantity of hops
necessary being about half the quantity of hops that would be ordinarily used for
hopping down the same quantity of beer in the cask.
In carrying out my said Invention, I pass or filter beer during or after fermenta-
tion through a layer or layers of hops placed in the improved or other filter, as
herein-before described, into a racking back or other suitable vessel of sufficient

page_text: size to receive the whole quantity of beer operated upon, after which the whole
or any desired portion of the saturated hops is pressed to remove the beer there-
from, or otherwise treated, and the hops can afterwards be used in the copper.
By the foregoing treatment, the essential oils of the hop, which it is well known
volatilize upon boiling, are preserved, and the desired aroma and flavour are imme-
diately imparted to the beer, which at present can only be obtained after the beer
has been hopped down and shived for some time.
The beer is also clarified and purified by the removal of the feculent and yeasty
particles.
The objection to the large quantity of dry hops so often used in the carriage
casks is overcome.
The accompanying Drawing is intended to serve as an illustration of a practical
and convenient way of constructing the apparatus, in which a is a bucket or
receptacle fitted with trays 6 holding hops. c is a cross head, through which passes
a screw ffitted to a lid d and supplied with a wheel handle e in such manner that
the lid d can be removed and firmly fixed in place. g is an inlet pipe, and h
outlet.
From what has been said before the mode of using the apparatus needs no
further description.
In witness whereof, I, the said John Hodson, have hereunto set my hand
and seal, this Twenty-sixth day of July, in the year of our Lord One thou-
sand eight hundred and seventy-eight.
