of Finings for the Use of Brewers and others.
We ALEXANDER WILLIAM GILLMAN and SAMUEL SPENCER both of the Castle
Brewery, St. George's Road, Southwark in the County of Surrey, Consulting
Practical Brewers and Analytical Chemists do hereby declare the nature of this
invention to be as follows
The invention has for its object improvements in means or apparatus employed
in the preparation of isinglass finings for the use of brewers and others whereby
the operation of passing the finings through the sieve is greatly facilitated.
For this purpose the finings after being duly "cut" or dissolved by an acid
in the usual way are passed through a sieve within which is arranged a brush which
in addition to a rotating motion is provided with a rising and falling motion. By
these means the brush descends onto the sieve bottom and there makes a partial
rotation thereby forcing the finings therethrough, it then rises again, partially
rotates and again descends and rotates on the bottom of the sieve, the rising and
falling and rotating motions are so arranged as to cause the brush to descend
on to a fresh portion of the sieve bottom at each motion thereby securing an equal
action over the entire surface thereof.

We, ALEXANDER WILLIAM GILLMAN and SAMUEL SPENCER both of the Castle
Brewery St. George's Road, Southwark in the County of Surrey, Consulting
Practical Brewers and Analytical Chemists, 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 invention has for its object improvements in means or apparatus employed
in the preparation of isinglass finings for the use of brewers and others whereby
the operation of passing the finings through the sieve is greatly facilitated.
For this purpose the finings after being duly "cut" or dissolved by an acid
in the usual way are passed through a sieve within which is arranged a brush, which
in addition to a rotating motion is provided with a rising and falling motion. By
these means the brush descends onto the sieve bottom and there makes a partial
rotation thereby forcing the finings therethrough, it then rises again partially rotates
and again descends and rotates on the bottom of the sieve the rising and falling and
rotating motions are so arranged as to cause the brush to descend onto a fresh portion
of the sieve bottom at each motion thereby securing an equal action over the entire
surface thereof.
And in order that our said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation and Figure 2 is a plan of means or apparatus constructed
according to our invention to be employed in the preparation of finings for the use
of brewers and others whereby the operation of passing the fining through the sieve
is greatly facilitated.
"
The finings after having been "cut or dissolved by an acid in the usual way are
led by a suitable trough or conduit (not shown) into a sieve a which is fixed in
position on a suitable framing and over a trough or conduit 6 which conducts the
finished finings away to a suitable receiver. Within the sieve a is arranged a brush c
which is fixed to the lower end of a shaft or axis d mounted loosely in bearings
carried by the cross frame e in such manner that in addition to being capable
of rotating therein, such shaft or axis d is also capable of freely rising and falling
in its bearings within certain limits.
The shaft or axis d is driven in the following manner. On such shaft or axis d
is fitted a bevelled pinion d¹ through which such shaft is capable of freely sliding
up and down but which is controlled to rotate therewith by means of a key way and
feather as is well understood. The said bevelled pinion d¹ is driven by a bevelled

page_text: pinion f fixed on a shaft or axis f which is mounted in bearings fixed on the cross
frame e and on which are mounted the fast and loose pulleys f², f³.
The rising and falling motions are given to the shaft or axis d and consequently
to the brush c by means of a cam 4 (shown separately at Figure 3) assisted by
a weight or weights d³. This cam is fixed on the shaft or axis and acts upon one
end of a lever g the other end of which acts upon the underside of a collar d² fixed
on the shaft d. The weight or weights d³ carried by the shaft d being employed
to retain the brush c with some amount of pressure in contact with the bottom of the
sieve a except when it is raised by the cam f.
с
By these means the brush c, will be caused to descend on to the bottom of
the sieve a where it will make a partial rotation thereby forcing the finings
therethrough, it will then rise again, partially rotate and again descend and partially
rotate on the bottom of the sieve the rising and falling and rotating motions are
so arranged as to cause the brush c to descend on to a fresh portion of the sievo
bottom at each motion thereby securing an equal action over the entire surface
thereof and unclogging or freeing it from solid particles which may be held
in the meshes of the sieve.
We would here remark that the means for giving the rising and falling and
rotating motions to the brush c may be varied without departing from the peculiar
character of our invention.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. The peculiar combination and arrangement of means or apparatus employed in
the preparation of finings for the use of brewers and others substantially as herein
shown and described.
2. In combination with a sieve, a brush which has rising and falling and rotating
motions substantially as herein shown and described and for the purpose stated.
