I, SAMUEL EDWARD FIELD, of Lewins Mead Brewery, Bristol, brewer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to malting as carried on in ordinary malting buildings in
which corn is germinated upon floors supplied with the air necessary for germination
through windows or other openings in the walls.
The objects of the invention are to facilitate the healthy growth of the corn,
as carried on in the buildings aforesaid, and to render such growth independent of
the conditions as to moisture, temperature and purity, of the atmosphere; such
conditions being frequently unfavourable to the healthy germination of the corn on
the malting floors.
Under this invention, the windows aforesaid are closed and the air, having first
been attemperated, inoistened and purified by any suitable means, is delivered
by means of a fan, or other device having the same effect, in a regular current over
the growing corn, and finally finds exit through openings in the walls or roof so
arranged with regard to the inlets as to ensure the current of air being uniformly
distributed throughout the floor. The air may be supplied to the growing floors
in various ways to suit the special circunstances of different buildings. Where
convenient, the air may be conducted to the floors through hollow columns supporting
the floors, by connecting such columns with the air supply from the fan; the air being
delivered through perforation in the columns at a suitable height above the level of
the corn. In another case, the air from the fan is conducted to a main air trunk
having branches for delivering the air to and over the floors.
Under another arrangement, the walls of the malt house are built with hollow
spaces constituting air passages, the air from the fan being delivered into these
spaces and thence over the growing corn through suitable apertures in the inner face
of the walls.
Other methods of carrying the air from the fan and distributing it over the various
floors may be adopted.
By this invention more regular germination of the grain is obtained owing to the
conditions existing in the air supplied to it being under control and kept favourable.
Good malt may be made all the year round, and the necessity of discontinuing the
process of malting through the hottest part of the year is obviated.
Further, the disadvantages due to too low a temperature of the atmosphere are
overcome.

I, SAMUEL EDWARD FIELD, of Lewins Mead Brewery, Bristol, 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:-

page_text: This invention relates to malting as carried on in ordinary malting buildings in
which corn is germinated upon floors supplied with the air necessary for germination
through windows or other openings in the walls.
The objects of the invention are to facilitate the healthy growth of the corn,
as carried on in the buildings aforesaid, and to render such growth independent
of the conditions as to moisture, temperature, and purity of the external atmosphere;
such conditions being frequently unfavourable to the healthy germination of the corn
on the malting floors.
According to this invention, the windows aforesaid are closed when the external
atmosphere is unsuited for malting, and the air, having first been attemperated,
purified, and moistened by any suitable meaus, is delivered by means of a fan,
or other device having the same effect, in a regular current over the growing corn,
and finally finds exit through shafts or openings so arranged with regard to the
inlets as to secure the current of air being uniformally distributed throughout
the floor. The air may be supplied to the growing floors in various ways to suit the
special circumstances of different buildings. Where convenient, the air may be con-
ducted to the floors through hollow columns supporting the floors, by connecting
Buch columus with the air supply from the fan; the air being delivered to the floors
through perforations in the columns provided at a suitable height above the level of
the corn.
According to another arrangement, the air is conducted to a main air trunk which
is carried up against one of the walls of the malt-house and which has branches
extending around the walls for delivering the air to and over the floors.
According to yet another arrangement, the walls of the malt-house are built with
hollow spaces constituting air passages; and the air from the fan is delivered into
these spaces, and thence over the growing corn, through suitable apertures in the
inner face of the walls.
Other methods of carrying the air from the fan and distributing it over the various
floors may be adopted.
Referring to the accompanying sheets of illustrative drawings, Fig. 1, represents a
sectional plan of part of a malt-house constructed and arranged in accordance with
one method comprised in this invention. Fig. 2 is a section on the line x, x, Fig. 1.
Fig. 3 is a section on the line y, y, Fig. 1.
According to this method, when the external atmosphere is, in consequence of un-
favourable conditions as to moisture, temperature, and purity, or from other cause,
unsuited for inalting purposes, the windows of the germinating rooms are closed and
the air is drawn by a fan which is diagrammatically indicated at a, Fig. 1, through
the pipe b from the exterior of the building into a suitable attemperating, moisten-
ing, aud purifying appliance such as is well known. This appliance is diagrain-
matically indicated at c, Fig. 1. The fau a is driven by the gas engine or other
motor indicated at a¹, Figs. 1 and 3. Froin the appliance c the air is drawn
through the pipe 6 into a similar appliance c from which, moistened and
attemperated to the requisite degree, the purified air is drawn through the pipe 61
to the fan a. Thence the air is delivered through the pipe to the main air trunk d
situated at or about the ground level, as seen more particularly at Fig. 3. From the
trunk d extend, at suitable distances apart, pipes e which run under the ground
floor from one end of the building to the other. By branch pipes f the pipes e com-
municate with the lowermost series of the columns g which carry the floors h of the
structure. The columns g are hollow, and each communicates with that next above
il throughout the series of germinating stories. All the columns throughout the
several germinating floors, except those columns which are enclosed in the air exit
shafts and those which continue thence to the ground floor, have orifices; provided
at a suitable height above the floors.
Tho unperforated columns are indicated on the drawings by g¹.
At Fig. 4 is shown, drawn to an enlarged scale, a column g. Fig. 5 is a section on
the line x, x¹, Fig. 4, and Fig. 6 is a section on the line v¹, v¹. Fig. 4.

page_text: The air issuing from the columns y through the orifices ; distributes itself over the
growing corn on the floors.
The air delivered over the ground floor finds exit through the lower ends of the
exhaust shafts i. The air delivered over the floors above passes into the same shafts i
through apertures i provided therefor. The air ascends in the shafts and is dis-
charged therefrom above the roof through the apertures i³, Fig. 2.
At Fig. 7 in the accompanying drawings is illustrated a modified method of
conveying and distributing over the floors h the air after, as aforesaid, it has been
purified, moistened, and attemperated.
According to this arrangement, the air is delivered from the fan to the main air
trunk which is carried up against one of the walls of the malt-house. Branch air
trunks extend around the walls above each floor h. The air conveyed by them
issues to the floors through orifices provided at suitable distances apart.
For the escape of the air after it has passed over the grain, air exit shafts, or the
like, are provided after the manner hereinabove described with reference to
Figs. 1 to 6 of the accompanying drawings.
At Fig. 8 is shown a further modification in respect of supply of air to the
malting floors h. In this modification the air is delivered from the fan into channels m
provided in the masonry of the malt-house walls and extending round the building
above each germinating floor. These channels are fed from a main air trunk. The
air issues from the channels m through the orifices m', and, after passing over the
floors, escapes through exit shafts or their equivalent.
In malting according to the system which constitutes this invention, more regular
germination of the grain is obtained owing to the conditions existing in the air
supplied to the grain being under control and kept favourable. Good malt may be
made at all seasons of the year and continuously.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same to be performed, I would have it understood that I do
not confine myself to the particular methods of conveying the air to the malting
floors and distributing it over them hereinabove described and shown in the
accompanying drawings, as other methods may obviously be adopted, but what
I claim is:-
A system of malting in ordinary malt-houses and on ordinary malting floors by air
previously purified, moistened, and attemperated in any suitable appliances (such as
are well known); the said air being conducted under pressure from a fan or like
appliance to the growing floors and distributed over the grain thereon, and there-
after escaping therefrom by suitable exit shafts, or their equivalents, substantially as
hereinsbove described with reference to the accompanying drawings.
