New or Improved Malting Apparatus.
We, PIERRE-FRANÇOIS VAN DER GUCHT, of 13, Rue Eliaerts, Borgerhout, near
Antwerp, Belgium, Manufacturer, and AUGUSTE KREPS, of 2, Fossé aux Génisses,
Antwerp, Belgium, Brewery Foreman, do hereby declare the nature of this
invention to be as follows:-
The apparatus forming the object of the present invention serves for germinating
grain, detaching the roots and cleaning and polishing the malt.
This apparatus is composed of a shaft turning in horizontal bearings, and
terminated at one of its extremities by a hollow cylinder with four hollow
projectures with flanges to which are adjusted four hollow branches arranged in the
direction of the radii of the cylinders; the four hollow branches are adjusted with
flanges to a rim, to which is adapted a toothed wheel to communicate the movement
to the apparatus.
To the other extremity of the shaft is also wedged a plate or rim and between
the two rims a metallic drum is fixed concentric with the shaft, and provided,
according to its generatrix with openings which can be shut by means of small
slides, and through which the detached roots of the malt pass, as will be seen
hereafter.
Grooves are made in the rims on their exterior circumference and inside
surface, obliquely with their radii, and into these grooves sectors, or malting sacks,
containing the malt, slip.
These sectors which are forced by the grooves to approach their exterior
extremities, form between these extremities and the interior drum, an annular
chamber into which the fluids, air, liquids, or gas are introduced for the operation
of the malt, these are driven by the back-shoving effects of the movement of the
rim and the sectors and pass by the four hollow branches and the hollow extremity
of the hollow shaft cylinder into the atmosphere or are utilized for some industrial
purpose or other.
The sacks or malting sectors are each composed of two cheeks in iron, allowing
the sectors to slide into the grooves of the rims, which they do with a certain
amount of play; these cheeks are crossed by iron stems to which is attached a
wire-gauze forming the covering of the sectors; this wire-gauze has iron points
serving as rasps for detaching the roots from the malt; the sectors are closed by
means of a lid which can be removed for the filling and emptying.
The sacks or sectors are longitudinally crossed by pointed galvanized wires to
which a spring arrangement communicates shocks which facilitate the detaching of
the roots from the malt; this arrangement only works when the malt is supposed
to have become sufficiently dry.

We, PIERRE-FRANÇOIS VAN DER GUCHT, of 13, Rue Eliaerts, Borgerhout, near
Antwerp, Belgium, Manufacturer, and AUGUSTE KREPS, of 2, Fossé-aux-Génisses,
Antwerp, Belgium, Brewery Foreman, 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 present invention concerns a malting drum for germinating and drying
grain, detaching the radicles and cleaning and polishing the malt.
The special object of this apparatus is to pass the grain through all the phases
of the malting without having to undergo all the manipulations to which it is
ordinarily subjected and which considerably increase its cost-price.
This result is obtained by submitting the grain introduced into the sectors or
malt-bags of the drum, to the action of cold or hot air, steam, gases or other
fluids inhaled by the drum during its rotation and which in passing through the
sacks and their contents, urge on the germination or effectuate the drying of the
grain.
The degerminating and the cleaning of the malt also take place in the malt
sacks which, for this purpose, are provided with interior points and shaking
contrivances.
To obtain the above-mentioned effects, the drum and the sectors or malt-
pouches are respectively arranged in a suitable way and provided with suitable
contrivances as will be more completely described in course of the present
Specification and pointed out in the claims.
In the annexed drawing a practical form of construction of this apparatus is
given by way of example.

Fig. 7 is a lateral view of a sector.
Fig. 8 is a sectional view of the spring moulding.
In the different figures the same letters indicate corresponding parts.
A are the sectors or malt bags, B indicates the empty spaces separating the
sectors, B and B are the two lateral circular plates of the drum D, C is an empty
annular space comprised between the interior side D of the drum and the interior
extremity of the sectors, E indicates the tubes for the outlet of the air, steam or
other fluids, F is a hollowed hub, the interior of which forms the outlet chamber, G is a
toothed crown fixed to the drum, H is the tube leading the fluids to the outside or
into another apparatus; K is the shaft of the drum, L are the arms of the drum D,
M is a hub upon which the arms L are fixed, finally N indicates slide-plates for
clearing the radicles.
In the sectors or malt pouches A, I indicate crosspieces, J lateral iron-cheeks
connected by the cross-pieces; O is a wire-gauze fixed on the cross-pieces I and
provided with points O₁; P is a cross-bar serving at the same time as an axle to
the hinge R; R is the hinge of the door S serving to fill and empty the sectors;
T indicates galvanized wires provided with points; V₁ are springs placed on

page_text: the extremities of the wires T and serving to stretch these latter; W W₁ are iron
plates holding the springs and to which are fixed the extremities of the wires T,
X are iron rods fixed to the bars W and which bear a washer at their ends; Y are
mouldings fixed on the plates B₁ B" of the drum, Fig. 4, and provided with a
cylindrical hole containing a spiral spring pressing on the washer of the corre-
sponding rod X, Figs. 7 and 8.
The mode of fixing the malting drum is not indicated in the drawing; the said
drum may rest upon any pedestal supports suited to local circumstances; moreover
the malting-drum is placed and turns in a closed envelope not indicated in the
drawing and which communicates by suitable conduits with the producing
apparatuses or the reservoirs for hot air, gas, water or other fluids.
The shaft K of the drum has, on its inside extremity, a coupling-box with
collar upon which the hollow hub F is bolted, the said hub having four tubes on
its periphery to which are fixed the four conical tubes E arranged crosswise and
which have their other extremities connected with tubes cast with the
plate B.
On the other end of the shaft K the second hub M is wedged, this said hub
being massive and provided with four extensions joined to the arms L forming a
cross-work and the extremities of which are fixed to the collars of the plate B".
The plates B B are provided with circular grooves in which are fixed the
lateral ends of the curved metallic plates D which form the interior side of the
drum.
Between the plates D are arranged transversely, free spaces closed by slide-
plates N.
At the moment the radicles are separated from the malt, through the means
described in course of the present Specification, the slide-plates N are withdrawn
and the radicles are expelled through the free spaces of the drum.
The two plates B¹ B₁ have, on their inside faces, grooves A¹ the direction of
which is oblique relatively to the radii of the drum.
The grooves A¹ of the two plates are face to face so as to be able to fit the sectors
or malt sacks A in them, which are thus fixed between the two plates B₁ B" so that
their inside extremities touch one another so that the fluids sucked can be forced
through the grain in the sacks A. The sectors are slipped with their cheeks J into
the grooves A¹ and held in position by any suitable catching contrivance.
The shaft K and its hub F turn in ordinary pedestal supports fixed to the cover-
ing but which as well as this latter, are not shown for the clearness of the drawing.
Outside the covering of the drum the tube part H of the hub F communicates
with the fixed tube H¹ by means of a stuffing box which secures the tightness of the
joint; moreover the drum-covering is provided with a door to allow the introduction
of the grain into the sacks.
The plate B¹ has a toothed crown G Fig. 4 which serves to transmit a rotary
movement to the shaft K and consequently to the malting drum.
The position of the sectors or malt sacks A with respect to the rotation axle is
such that, through the rotary motion of the apparatus, this latter acts as aspirator.
The fluids sucked pass through the empty spaces B comprised between the sectors,
acting upon the malt contained in the sacks A in passing through the said sacks,
and are repelled towards the exterior through the annular chamber C, the conduits E,
the chamber F, the tubing H and the pipe H¹ which carry them outside or lead
them to another apparatus or a reservoir to be served for other manufacturing
purposes.
Each of the sectors or malt sacks A Figs. 6 and 7 is formed with the two iron
cheeks J which allow the slipping of the sector into the grooves A¹ the form of
which they adopt with a certain play; these cheeks J are united by means of iron
rods I upon which the wire-gauze O is fixed the said gauze forming the covering
of the sector.
This wire-gauze is provided with wire points 01 acting as graters to detach the

page_text: radicles from the malt. One end of the gauze is fixed to the rod P which forms the
axle of the hinge R of the door S which serves to fill and empty the sector.
Inside the sector, the galvanized wires T are arranged longitudinally, to which
wire knots provided with points U are fixed.
The wires T have their ends fixed to the plates W W₁ and their tension is thus
secured by spiral springs placed between the plates and the ends of the sectors A.
To the two ends of the plate W iron rods X are fixed, the said rods being
provided at their free ends with washers Z fitted in the cylindrical hollows of
mouldings fixed on the outside faces of the plates B¹ B". In these cylindrical
hollows spiral springs z are arranged compressed between the bottom of the hollows
and the washers Z of the rods X the object of which is to shake the plates W & W¹
with the rods T and consequently the grain contained in the sectors and to cause
the radicles to fall.
The shaking is produced by a suitable contrivance against which the ends of the
plates W strike during the rotation of the drum. This contrivance must be
removable in order that the shaking be only performed when the grain has
acquired the desired degree of dryness, or at any desired moment.
The whole malting operation takes place in the sectors A which receive the grain
coming from the steeping-vats. This grain is introduced into the sectors through
the doors S and is distributed in thin layers, as will be easily seen by the
dimensions of the sectors.
The arrangement of the oven is indifferent. The fluids employed are sucked
during the rotation of the sectors A and are driven out through the tube H¹.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
