PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drying Grain, Malt, Fibrous,
Textile, and Vegetable Substances, and especially for Heating
Malt Prior to Grinding and Mashing.
HENRY WILSON Thomas Lane Knotty Ash near Liverpool Engineer do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to obtain increased & more uniform distribution of
power from the apparatus for which I obtained Letters Patent No. 11208 1886 the
improvement consisting mainly of the more uniform distribution of the points of
draught or suction which in the above named apparatus are confined exclusively to
the top of the room, while the heating or tempering media is placed at the bottom.
The first part of the improvements consist in placing a series of tempering or
heating chambers or pipes in any convenient position under the roof or top & round
the sides & on the bottom of the room or case & so arranging the suction or draught
channels that uniform draught power is exerted throughout the whole mass, either
hot or cold air being used as required.
The second part of the improvements consist in the substitution of wood frame—
instead of metal-for the air pump or exhauster.

Improvements in Apparatus for Drying Grain, Malt, Fibrous,
Textile, and Vegetable Substances, and especially for Heating
Malt Prior to Grinding and Mashing.
I HENRY WILSON Engineer, 65 Merehall Street Bolton formerly of Thomas
Lane Knotty Ash Liverpool 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 object of these improvements is to obtain increased & more uniform power
in the apparatus for which I was granted a Patent in 1886 No. 11208.
The first part of the improvement is in the receptacle or case in which the
materials to be operated upon are placed this being made of wood or any
suitable material & when used for grain malt & the like the under part is conical
in shape & of perforated material to allow for the passage of air through the body
of grain placed therein-A series of metal pipes of any suitable form & serrated on
the surface to increase the heating power is placed under the lowest part of the
case & covered with wood or other material having openings opposite the pipes to
allow the air before passing through the contents to impinge upon the centres of
the pipes another series of pipes is placed inside the case close to the top & covered
in like manner-These pipes are heated by steam or hot air in which latter case
the pipes are made of sheet iron or copper & perforated to allow the hot air to pass
direct through the body of grain contained in the case- -Through the centre of the
case is placed a series of pipes of sheet iron perforated & connected to a main
channel leading to an exhaust pump, fan or escape pipe with a steam jet to induce
draught where the exhaust pump cannot be conveniently applied.
Another form of heating media is a vertical main steam pipe with radial branches
placed in the case this pipe & branches is cast with numerous projections on the
surface to intercept the passage of air between the main body of the pipes & the

page_text: perforated material with which it is covered-forming a narrow passage for the air
which is heated in this space before being drawn through the body of the grain
surrounding it.
The manner in which the apparatus is used is as follows-The substances (grain
malt fibrous textile & vegetable &c.) are placed in the case & closed up the air
pump or other exhausting medium is put in operation causing a current of air to be
drawn through the space between the heating media & the perforated covering
thereof & thence through the body or mass of substance in the case, the com-
munication with the air pump or exhausting media being with pipes or conduits
leading from the top & bottom of the case & opening between the outer covering
& inner perforated covering upon which the substance is placed these pipes or
conduits are connected to the air pump (when the pump is used) which is double
acting so that the down stroke of the pump draws the air up through the body &
the up stroke down through the body or mass of substance in the case the action of
the exhaust pump being arranged so that the draught is applied to the top & bottom
of the case alternately & ensuring uniform heating throughout.
