PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Treatment of Grain for the
Production of Malt.
I EDWARD CRADDOCK, of 146 Fenchurch Street, London E.C. Engineer, do
hereby declare the nature of this invention to be as follows:-
The apparatus consists of a case preferably drum shaped held on a central hollow
axle suitable supported to horizontally revolve. Across the inside of case are
lengths or struts of flat tubing perforated with small holes for exit of air which is
introduced in any suitable manner through the hollow axle and into the hollow
Each end of the drum is
struts by short pipes connected to the axle and struts.
closed by a movable wire gauze cover. The drum is arranged to be partially
immersed in water and to be removed from the same at will. The most convenient
manner to effect this is for a water tank to be arranged under the drun so that
it may be raised or. lowered. The grain is introduced into the drum through
a door in same, and when the necessary quantity is put in the door is closed,
and the tank raised for the water to soak the grain. After soaking for the
necessary time in one position the drum is slowly, revolved to stir or turn over the
grain without damaging it. When the soaking is wholly completed the tank is
lowered and the germinating allowed to take place; the necessary shifting of the
grain being effected by slowly revolving the drum. When the germination is
completed drying means are used, preferably consisting of hot air introduced
through the axle by fan or other known means which escapes through the small
holes in the hollow struts and permentes between the grain to dry it.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Treatment of Grain for the
Production of Malt.
I, EDWARD CRADDOCK of 7 Baalbec Road, Highbury, London, N. Engineer,
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:
This invention refers to an apparatus into which raw grain can be put and not
taken out again until the malt is produced, thereby greatly cheapening the
production. To enable my invention to be properly understood I will proceed to
describe the same with aid of the accompanying drawings.

A. is a metal drum having an opening B. for introduction of grain arranged, to
be closed by a door C; across the inside of drum are hollow flat tubes D, E, F,
perforated with small holes. The drum is connected to a central hollow axle G,
by means of the short tubes H, which communicate with the interiors of axle and
tubes D, and E, the tube F is placed in communication with the tube E, by means
of the short tubes I. Each end of the drum is covered by wire gauze cover J. to
enable air to circulate through the drum. To enable the grain to be soaked for the
usual germinating process, it is necessary that a portion of the drum should be

water. The most convenient way to arrange this is to place a movable tank K,
under the drum A, arranged to be lifted when the drum is to be in the water and
lowered when the drum is required to be out of the water. To facilitate this
arrangement it is preferred to counter balance the tank, by claims L, passing over a
suitable pulley and having sufficient weight attached to balance the tank. The
mode of treating grain by this invention is as follows: The raw grain is first
passed into the drum through the opening B, and the door closed, and the tank
elevated to allow the grain to soak. After soaking for the necessary time in one
position, the drum is slowly revolved to stir or turn over the grain, without
damaging it, the soaking is further continued until completed. When the tank is
lowered and the germination allowed to take place, the moving of the grain being
effected by slowly revolving the drum; when the germination is completed drying
means are used to dry the malt. For this purpose hot air is preferred which is
introduced by a fan or other known means through the hollow axle G. from whence
it passes into the tubes D, E, F, by the pipes H, and I, and escapes through the
small holes permeates the malt and drives it. When this operation is completed,
the malt can be removed either through the door hole B, or by removal of one of
the covers J.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
First. An apparatus for the treatment of grain for malt consisting of a drum
shaped grain holder, having an inlet closed by a door and the ends, closed by wire
gauze covers carried upon a hollow axle arranged to be revolved said drum having
hollow perforated struts across inside connected by short tubes to the hollow axle,
and a water tank to enable a portion of the drum to be immersed in water when
desired, substantially as described in the foregoing Specification; and illustrated
by the drawings.
Second. In the treatment of grain for malt a grain holder arranged to be revolved,
and partially immersed in water when desired the holder being arranged to enable
the water to permeate inside to soak the grain.
