PROVISIONAL SPECIFICATION.
Improvements connected with the Production of Pulp for Use in
Making Paper and Millboard.
We, EDWARD DAVIES, of 1, Harringay Villas, Green Lanes, London, N.,
Engineer, and HENRIETTA MARIANNE HARRIETT GOODFELLOW, of Cambridge
Cottage, Wood Green, London, N., married, do hereby declare the nature of this
invention to be as follows:-
According to this invention spent hops are treated as follows: If they are
received from the brewery in a wet state, the liquid is squeezed or pressed out of
them by rolls or presses, or both. If they have been pressed sufficiently at the
brewery, we do not squeeze or press them but put them direct into the apparatus
for loosening the seeds from the petals and stalks. This apparatus is made as
follows: In a galvanised iron or other metal trough is arranged a propeller worm
for propelling the hops along the said trough and for loosening the seeds from the
petals and stalks. After this operation the seeds, petals, and stalks are either
passed through a perforated revolving cylinder or over a sifting machine. These
take out the seeds and dirt the petals and stalks dropping out at the tail ends of
the machine, when they may be taken out to the usual beater engines and converted
into pulp for making millboard or paper. The seeds and dirt as they fall through
the sifter drop into a tapered spout through which they pass into a receptacle, but
while passing they are met by a horizontal blast of air to separate the dirt, such
blast of air being obtained by any usual means.

We, EDWARD DAVIES, of 1, Harringay Villas, Green Lanes, London, N.,
Engineer, and HENRIETTA MARIANNE HARRIETT GOODFELLOW, of Cambridge
Cottage, Wood Green, London, N., married, 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 machinery according to this invention for treating spent hops will be best
understood by describing the same with aid of the accompanying drawings, which
illustrate a sectional elevation of a factory and machines employed.
A, B, two floors, and C, the ground floor, D, a galvanized iron or other metal
trough, having a hopper mouth E, for the spent hops to be fed in, F, a revolving
propelling worm to stir up the hops as fed in and work them along, this stirring up
separates the seeds from the petals and stalks, which with the seeds when worked
along to the end fall down the chute G, into a cylindrical sifter H, supported upon
a shaft J, arranged to be revolved. K, supports for the sieve part L. This sifter
is set at an angle as shown so that the hop petals and stalks may work their way

page_text: through, and fall out at M, into a receptacle arranged to receive them previous to
which the seeds and dirt are sifted out and fall into the receptacle N, and thence
slide down the tube O, into a receptacle arranged to receive them, while the seeds
and dust are falling down tube O, they are met with a cross blast of air from a
blast fan P, which separates the dirt from the seeds.
When the spent hops are received from a brewery in a wet state, the liquid is
pressed out of them, a suitable press for this purpose is illustrated at Q; R, being
a perforated cylinder fitted with a lift door S, the piston T, being forced down by
screw gear U. If the spent hops are received from a brewery in a pressed state,
they are passed direct into the trough D, and the beating and stirring action of
the propelling worm loosens and separates the petals and stalks from the seeds.
After the petals and stalks have been obtained free of the seeds and dirt they are
passed into beater engines and converted into millboard and paper.
In some cases we may arrange a shaking or other sieve for the petals and pieces
of stalk to fall upon as they fall out of the cylindrical sifter to separate the petals
from the stalks. V, is a usual kind of elevator which can advantageously be used
for lifting the spent hops from the ground floor to the upper floor.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed: we declare that what we
claim is:
The apparatus for treating spent hops to separate the petals and stalks from the
seeds and dirt, and to give continuous working, consisting of a suitable trough
arranged for the spent hops to be fed into, internally fitted with a revolving
worm arrangement, a cylindrical sifter placed at an angle to receive the hops from
the trough having an exit at lower bottom end, a collector for the seeds arranged
underneath sifter, and a blast fan to give a cross blast of air to separate the dirt
from the seeds as they fall down, all substantially as herein described and illustrated
by the accompanying drawings.
