County of York, Engineer, and David Brown, of the same Place;
Pattern Maker, for the Invention of "AN IMPROVED METHOD OF AND
PROVISIONAL SPECIFICATION left by the said Thomas Broadbent
and David Brown at the Office of the Commissioners of Patents,
with their Petition, on 'the 9th December 1875.
We, THOMAS BROADBENT, of Huddersfield, in the County of York,
Engineer, and DAVID BROWN, of the same Place, Pattern Maker, do
hereby declare the nature of the said Invention for "AN IMPROVED
METHOD OF AND APPARATUS FOR EXTRACTING LIQUID OUT OF Hops," to be as
follows:-
This Invention consists in the employment of a centrifugal machine
or hydro-extractor for the purpose of extracting the liquid from hops.
The centrifugal machine is similar to those employed for drying fabrics,

page_text: the cage only being of somewhat different construction. The bottom of
the cage has a flange or rim of angle iron, and the sides of the cage
(which are made of perforated wrought iron instead of wire) fit inside
this rim or flange. The top and sides of the cage are connected
together, and the spindle passes through a boss in the top of the cage,
the whole being secured by set screws fitting on the top of the spindle.
Openings are left in the top of the cage for the introduction of the
hops. When the moisture or liquid has been extracted sufficiently the
top and sides of the cage are lifted off by suitably arranged pullies, the
hops adhereing to the sides of the cage until they are loosened, when
they fall out in compressed masses.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Broadbent and David Brown in the Great
Seal Patent Office on the 9th June 1876.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
BROADBENT, of Huddersfield; in the County of York, Engineer, and
DAVID BROWN, of the same Place, Pattern Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of December, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,

Her special licence that we, the said Thomas Broadbent and David
Brown, our executors, administrators, and assigns, or such others
as we, the said Thomas Broadbent and David Brown, our executors,
administrators, and assigns, should at any time agree with, and no.
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
METHOD OF AND APPARATUS FOR EXTRACTING LIQUID OUT OF Hops," upon the
condition (amongst others) that we, the said Thomas Broadbent and
David Brown, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, should
.

page_text: particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent..
NOW KNOW YE, that we, the said Thomas Broadbent and David
Brown, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed; to be particularly described and
ascertained in and by the following statement and accompanying Sheet
of Drawings:-
.
This Invention consists in the employment of a centrifugal machine
or hydro-extractor for the purpose of extracting the liquid from hops.
The centrifugal machine is similar to those employed for drying fabrics,
the cage only being of somewhat different construction. The bottom of
the cage has a flange or rim of angle iron, and the sides of the cage
(which are made of perforated wrought iron instead of wire) fit inside
this rim or flange. The top and sides of the cage are connected together
and the spindle passes through a boss in the top of the cage, the whole
being secured by set screws fitting on the top of the spindle. Openings
are left in the top of the cage for the introduction of the hops. When
the moisture or liquid has been extracted sufficiently the top and sides
of the cage are lifted off by suitably arranged pullies, the hops adhering
to the sides of the cage until they are loosened, when they fall out in
compressed masses.
In order that our Invention may be more fully understood we hereto
annex a Sheet of Drawings illustrative thereof.
Fig. 1 is a sectional elevation; and Fig. 2, a plan view.
A is the bottom of the cage which we make of sheet iron having a
rim of angle iron a around the edge. The sides B and top C are made
of the same material fastened together by angle iron b. The sides are
perforated for the escape of liquor. Spaces are left in the top of the
cage for the introduction of the substance to be dried. When the
machine is ready for work the top is placed on the spindle and fastened
down by the cross head D and nut E.
When it is desired to remove the substance from which the liquor has
been extracted the nut E is unscrewed and the top and sides lifted off
by the clip F and crane G; the material adheres to the sides, and when
the top and sides have been turned round so as to be clear of the other

page_text: portions the material may be loosened and falls out in hard masses.
Besides extracting the liquor contained in the hops or other substance
when they are placed in the cage. hot water may be introduced into the
cage and a second extract obtained.
. We claim, the improved method of drying hops by a centrifugal 5
machine, as herein described, and the improved construction of centrifugal
machines herein shewn and described.
In witness whereof, I, the 'said Thomas Broadbent, for and on
behalf of myself and the said David Brown, have hereunto set
my hand and seal, this Third day of June, in the year of our 1
Lord One thousand eight hundred and seventy-six.
