PROVISIONAL SPECIFICATION.
Improvements in Machinery for Treating Tea Leaf, for Sorting, Ball
Breaking, Separating, and Sifting Purposes.
We NATHAN WILLLAM HORATIO SHARPE, of 26 Perth Road Stroud "Green
London, N., Engineer, and SAMUEL ROBERT BAILDON of 1. Whitefriars Street,
London, Gentleman, do hereby declare the nature of this invention to be as
follows:-
According to this invention the tealeaf to be treated is first fed into a hopper
from whence it drops onto a shaking table or channel set at an angle. The ends
of this table rest upon spiral springs which may be raised or lowered by adjusting
means to give the table more or less angle. The shaking motion is imparted by
a cam arrangement intermittently meeting a projecting part from under side of
table preferably central. The bottom of the table is corrugated and perforated
with elongated perforations, the perforations being in sets to sift out different
size leaf as the whole. travel down. The receptacle under the table to receive the
sifted out tea is divided into divisions according to the sets of perforations, so that
the different size leaves when sifted out are kept separate. The coarse leaves not
sifted through, fall out at the end. By giving the table a strong shaking action
will enable it to act as a "ball breaker." Consequently the different operations
can be carried on in the same apparatus.

Improvements in Machinery for Treating Tea Leaf, for Sorting, Ball
Breaking, Separating, and Sifting Purposes.
We, NATHAN WILLIAM HORATIO SHARPE, of 26 Perth Road, Stroud Green,
London, N., Engineer, and SAMUEL ROBERT BAILDON of 1 Whitefriars Street,
London, E.C. Gentlemen 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 arrangement of machinery according to this invention is capable of being
used to perform several of the operations. tea leaf passes through in its treatment
to render it fit for the market. To enable the machinery to be properly understood,
we will describe the same with aid of the accompanying drawings:-

Fig. 5 plan of same.
A, a usual kind of feed hopper, into which the tea leaf to be treated is first
fed, from this hopper the leaf is fed on to the table B, this table is set at an angle
with its ends resting upon spiral springs C, these springs are held in adjusting
sockets to enable more or less angle to be given to the table, such adjustment
being effected by the set screws D. This table is given a shaking motion by means
of a cam E, intermittently meeting a projecting part F, on under side of table,
this part is preferred to be two rollers and placed in the middle of the length of
the table. The bottom of the table is corrugated and perforated with elongated
perforations H. These perforations are arranged in sets of different sizes in the
length of the table, to sift out different size leaves as the whole travel down.
Under the different sets of perforations is a spout J, to catch and conduct the
leaves as sifted through, into chests K,, placed underneath, so that the different
kinds of tea as sifted out are kept separate. The coarse leaves not sifted out fall
out at the end L. By giving the table a strong shaking action will enable it to act
as a ball breaker.
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 arrangement of a shaking table set at an angle, supported at each end on
springs, suitable means for imparting a shaking motion to the table, the bottom
of which is perforated and may be corrugated, the perforations being of elongated
shape, and sets of different sizes, a spout being arranged under each set of perfora-
tions to guide the sifted through leaves into chests, all as described and illustrated
by the accompanying drawings.
