PROVISIONAL SPECIFICATION.
Improved Apparatus for Separating Beer from Yeast.
I, EDWARD GEORGE MAJOR-LUCAS, of the "Bantam Cock," Northampton,
Brewer, do hereby declare the nature of this invention to be as follows:-
In skimming yeast off the beer in the fermenting vat there is combined with the
yeast a certain quantity, more or less, of beer, and it is the object of my invention
to produce an improved and effective apparatus for separating or filtering such beer
from the yeast after skimming the latter off the beer in the fermenting vat. For
this purpose I construct a back" with a sloping bottom and with a filtering
cloth fixed at a suitable distance from the top and supported at intervals in order
that it may maintain an approximately level surface. The bottom of the "back
is provided with a discharge aperture.
"
"
The "back" is conveniently constructed in the following manner: I form it
in two parts, an upper part and a lower part, the lower part having stretched over
the top thereof a filtering cloth which is supported at intervals by wood bars or
divisions which latter may extend from top to bottom of the lower part of the
back."
The upper part of the "back" fits closely over the upper portion of the lower
part of the "back" with the edges of the filtering cloth between such parts and
such cloth is stretched tight by the weight of the upper part of the "back" which
also makes a tight joint.
In using such apparatus the yeast is skimmed of the beer in the fermenting vat
and conveyed to the filtering "back," and on settling, the beer is at once filtered
through the cloth and can be immediately put back into the fermenting vat. By
the use of the present invention labor is saved, filter bags are dispensed with and
the beer is relieved of its bitterness through being so soon separated from the
yeast.
Improved Apparatus for Separating Beer from Yeast.
I, EDWARD GEORGE MAJOR-LUCAS, of the "Bantam Cock," Northampton,
Brewer, 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:-
In skimming yeast off the beer in the fermenting vat there is combined with the
yeast a certain quantity, more or less, of beer, and it is the object of my invention

page_text: to produce an improved and effective apparatus for separating or filtering such
beer from the yeast after skimming the latter off the beer in the fermenting vat.
For this purpose I construct a 'back" with a bottom which may be made to
slope towards the outlet end either by the construction of the "back or by tilting
the same, and I provide it with a filtering cloth fixed at a suitable distance from
the top and supported at intervals in order that it may maintain an approximately
level surface. The bottom of the "back" is provided with a discharge aperture.
My invention is illustrated in the accompanying drawings, in which:-
Fig. 1 is a plan of the complete apparatus, and
Figs. 2 and 3 are respectively a vertical longitudinal section and a vertical cross 1
section of the same, both being drawn to a larger scale than Fig. 1, in which latter
Fig. the filtering cloth is not represented.
The "back" is conveniently constructed in the following manner. I form it
in two parts, an upper part a and a lower part a', the lower part a¹ having stretched
over the top thereof a filtering cloth 6, which is supported at intervals by wood
bars or divisions c c¹, the two side ones of which latter may extend from top to
bottom of the lower part a¹ of the back; these bars form a framing to carry the
bars c and support them a short distance above the bottom.
The upper part a of the "back" fits closely over the upper portion of the lower
part at of the "back" with the edges of the filtering cloth 6 between such parts,
and such cloth b is hooked over the hooks e and stretched tight by the weight of
the upper part a of the "back," which also makes a tight joint.
The outlet end of the "back" is provided with a cock d.
Insing such apparatus the yeast is skimmed off the heer in the fermenting vat
and conveyed to the filtering "back" and, on settling, the heer is at one filtered
through the cloth and can he immediately drawn off through the reek № and put
back into the fermenting vat.
By the use of the present invention labour is saved, filter bags are dispensed with,
and the beer is relieved of its bitterness through being so soon separated from the
yeast.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:
1. The improved apparatus for separating beer from yeast constructed and
arranged substantially as herein set forth.
2. Improved apparatus for separating beer from yeast consisting of a "back"
constructed of an upper part and a lower part, the upper part fitting within and
resting upon the upper edge of the lower part, bars fixed at intervals across the
lower part, a filtering cloth supported on said bars and strained and held in position
on the lower part by the upper part, and a draw-off cock in the lower part, sub-
stantially as herein set forth.
3. Improved apparatus for separating beer from yeast comprising a "hack"
fitted with a filtering cloth and a draw-off cock, substantially as herein set forth.
Dated this 10th day of December 1897.
