WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters

Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto

Paul Rapsey Hodge, my executors, administrators, and assigns, or such
others as I, the said Paul Rapsey Hodge, my 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 "THE TREATMENT AND USE OF A NEW MATERIAL IN
MAKING OF PAPER OR OTHER COMPOUNDS OF VEGETABLE PULP," upon the con-
dition (amongst others) that I, the said Paul Rapsey Hodge, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should 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 I, the said Paul Rapsey Hodge, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention consists in using of what is technically called by brewers
(spent hops), in combination with or without other fibrous materials, in the
manufacture of paper, paper machie, patent fibrous wood, millboards, or any
compound made of vegetable pulp, and also in the manner of treating and
preparing the spent hop.
My Invention, firstly, consists in taking of spent hops after the brewer has
done with them, and digesting them at a heat (under pressure with steam of
about from 220° to 250° Ft, and then pressing the feculent or mucilagenous

page_text: matter from them. They are then steeped in cold water for a short time, and
if for common paper, they are immediately put into the pulping engine and cut
up into pulp in the ordinary way.
If for superior paper, they are steeped in a solution of bleaching liquor, or a
solution of hydrocholoric acid and water, or any of the solvents for gallic or
tannic acids, both of which are present at all times in spent hops. They are
then treated in the same manner as before, and used either alone or in combi-
nation with any other fibrous material for the purposes of making a paper,
paper machie, patent fibrous wood, millboards, or any of the compounds
wherein vegetable pulp is used.
My claim is for the manner of treating, preparing, and use of spent hops in
the manufacture of paper, paper machie, patent fibrous wood, millboards, or
any other compound made of vegetable pulp, as fully described.
In witness whereof, I, the said Paul Rapsey Hodge, have hereunto
set my hand and seal, this Twenty-eighth day of May, in the year
of our Lord One thousand eight hundred and sixty.
Witness,
R. B. NICHOLSON.
PAUL R. HODGE. (L.S.)
