PROVISIONAL SPECIFICATION.
Improvements in the Treatment of Spent Hops for Preparing
the same for Use as a Stuffing Material, and in the Machinery
therefor.
We, EDWARD DAVIES of 1 Harringay Villas, Green Lanes London, N.
Engineer, and HENRIETTA MARIANNE HARRIET GOODFELLOW, of Cambridge
Cottage, Wood Green, London, N. Married, do hereby declare the nature of this
invention to be as follows:-
The primary object of this invention is to so prepare spent hops as to render
them suitable for use for stuffing all kinds of upholstery; such as sofas, seats,
cushions, couches, mattresses, beds, quilts, and the like. According to this invention
we first wash the spent hops as received from the breweries and cleanse them to do away
with the smell of the beer; then press them either with presses or rolls, or both; then
pass them through steam jacketted worm troughs. The worm pushes the hops along
the drying troughs and at the same time loosens the leaves, stalks, and seeds from
one another. From the drying troughs the hops pass through a revolving perforated
cylinder, which takes out the seeds and dirt. The hops are then operated upon by
a fan which separates the leaves from the stalks for the best quality of stuffing.
For an inferior quality the stalks are left. The latter may be further treated by
passing them between rolls to crush them to render them suitable for use in
commoner kinds of stuffing.

Improvements in the Treatment of Spent Hops for Preparing
the same for Use as a Stuffing Material, and in the Machinery
therefor.
We, EDWARD DAVIES, of 1 Harringay Villas, Green Lanes, London, N.,
Engineer, and HENRIETTA MARIANNE HARRIET 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 primary object of this invention is to so prepare spent hops as to render them
suitable for use for stuffing all kinds of upholstery: such as sofas, seats, cushions,
couches, mattresses, beds, quilts and the like.
According to our invention we first wash and clean the hops as received from
breweries to get rid of the smell of the beer, then press them either with presses
or rolls or both, and then pass them through a steam jacketted worm to loosen and
separate the petals from the stalks and seeds.
From the drying worm or trough the petals, seeds and stalks are passed through
a revolving perforated cylinder which takes out the seeds and dirt.

page_text: To enable the invention to be fully understood we will proceed to describe the
same with aid of the accompanying drawings.
Fig. 1, illustrates a sectional side elevation of the steam jacketted worm and
sifting cylinder with accessories.
Fig. 2, a cross section of a drying worm.
Fig. 3, a sectional elevation of a kind of washer for cleaning the hops.
A, is a metal casing or cylinder: B, the jacketted part for steam. C a hopper
for feeding in the spent hops. D, an outlet for same. Through the centre of the
casing A, is a shaft E, arranged to be revolved by power. This shaft is fitted
with vanes F, to stir up and separate the hops as they are fed in. These vanes
are set at an angle so that they may at the same time as they stir up the hops
propel them slowly along the bottom when they are partially dried by the heat of
the steam, when the hops come to the end of the casing they fall down the
chute G, into the perforated sifter. This consists of a perforated cylinder H,
carried on central shaft J. K, supports from shaft to hold sides of cylinder. This
cylinder is also arranged to be revolved by power. The hops fall into this cylinder
and are gradually worked along by the cylinder being placed at an angle, during
their passage the seeds are sifted out, the petals and stalks then falling out at the
lower end on to a chute L, over the mouth of a blast fan M, the blast blowing the
petals forward and leaving the stalks behind, by this means the petals of the hops
are separated from the stalks. The latter can be treated to render them suitable
to be used in the commoner kind of stuffing by passing them between rolls to crush
them.
Referring to Fig. 3. This washer consists of a casing N, with vertical spindle O,
arranged to be driven by power.
Upon the spindle within the casing are a number of horizontally placed arms P,
the bottom one of the arms has a number of vertically held pegs Q, to stir up the
hops that may settle down at the bottom.
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 :
1. The manner of treating spent hops to obtain the petals of same loose and free
of seeds dirt and stalks hereinbefore described.
2. The arrangement of machinery for treating spent hops herein before described
and illustrated.
3. The combination of the drying and loosening worm arrangement, with a
cylindrical sifter set at an angle.
4. The combination with the parts set out in the preceding claim of an air blast
to act upon the petals and stalks as they fall out of the sifter, to separate one from
the other.
