for an invention of IMPROVEMENTS IN "FALSE BOTTOMS
OR "DRAINAGE
"
PROVISIONAL SPECIFICATION left by the said Alexander William Gillman
and Samuel Spencer at the Office of the Commissioners of Patents on the
9th June 1882.
ALEXANDER WILLIAM GILLMAN and SAMUEL SPENCER both of the Castle
Brewery St. Georges Road, Southwark, in the County of Surrey IMPROVEMENTS
IN FALSE BOTTOMS OR DRAINAGE PLATES FOR BREWERS' DISTILLERS' AND
VINEGAR MAKERS' MASH TUBS.

"
The Invention has for its object improvements in "false bottoms" or drainage
plates" for brewers' distillers' and vinegar makers' mash tubs,
Heretofore "false bottoms or" drainage plates" for mash tubs have been made
flat and have been perforated with small circular holes or with a number of long
slotted openings therein. This form of "false bottom is liable to be readily
choked thereby reducing the efficiency of the apparatus.
"
According to our Invention we also employ a perforated flat "false bottom" but
on the upper side thereof we fix one or more hollow rings, cones, cylinders or other
forms rising to a suitable height the sides or walls and tops of which are perforated
in any suitable manner but by preference with long narrow slits and in order to
give a free vent to the liquor percolating through these perforated walls to the
interior of the hollow rings, cones cylinders or other forms we entirely or partially
remove that portion of the flat "false bottom" which is open to the interior of the
hollow rings, cones, cylinders or other forms leaving only sufficient material to
furnish the required strength.
19
Or the "false bottoms or "drainage plates" may be cast or constructed with
the hollow rings cones or cylinders or other forms in one piece with the flat portion
and for large sizes the improved "false bottoms" or "drainage plates" are made in
sections for convenience of handling.

page_text: cone or as shown at Figure 8 they may be made of circular or ring form and
instead of applying a number of separate drainage appliances c¹ around the side of
the mash tub as shown at Figures 1 and 2 a continuous inclined ring fitting
against the side of the mash tub may be employed.
These improved drainage appliances may be of other suitable forms and they may
be of any convenient height and the sides or walls and tops thereof are perforated
in any suitable manner but by preference we make them with long narrow slits
as shown and in order to give a free vent to the liquor percolating through these
perforations to the interior spaces of the hollow rings, cones, cylinders or other
forms of our improved drainage appliances cl we entirely or partially remove that
portion of the Hat "false bottom " c which is open to the interior of the hollow
rings, cones, cylinders or other forms c¹ leaving only sufficient material to furnish
the required strength.
In the drawings we have represented the flat "false bottom" c formed separately
in the usual way but with our improved drainage appliances c¹ screwed or
otherwise fixed thereon but it will be readily understood that the "false bottom" c
or each section thereof and the parts c¹ fixed thereto may be cast in one piece.
Having thus described the nature of our said Invention and the mode in which
we carry the same into effect we would have it understood that what we claim is
the application to flat "drainage plates" or "false bottoms" c of mash tubs of
improved drainage appliances c¹ substantially as herein shown and described.
In witness whereof I the said Alexander William Gillman have hereunto set
my hand and seal this Eighth day of December in the year of our Lord
One thousand eight hundred and eighty two.
