An Improved Method and Means for Turning and Drying Malt and
Grain.
I JOHN REDGRAVE of No. 128 Princess Road Edgbaston, Birmingham, in the
County of Warwick Gentleman do hereby declare the nature of this invention to
be as follows:-
The Invention consists of a very simply constructed and inexpensive Machine called
"The Malt Turner" which has for its object an improved process in the mode of
turning over and drying of Malt and grain in one continuous regular uniform manner
from the time of its being deposited on the Floor, of the drying Kiln until the drying
process is completed so that every grain of Malt may be regularly turned and
equally dried to any degree of temperature, and to any color that may be
required, whether Pale, Amber, Brown, high-dried, or otherwise and with such a
soundness and uniformity as will bave the effect to retain its farinaceous and Saccharine
Properties.
Kilns for the reception of my Invention must be built upon a circular plan, but
1 can apply it to any existing Kilns which may be of a square or oblong form by a
simple reconstruction in the interior arrangement of such Kilns..
I propose in the centre of the Floor of the Malt-Kiln to fix an Iron Standard or
post, to which will be attached the machine consisting of a large horizontal cogged
wheel, and to this wheel are fixed one or more arms both extending in the same
direction from the centre to the circumference of the Kiln, and resting on a bearing
or support fixed on the side of, or in the wall whereon it travels by the aid of small
rollers, or other equivalents, which may be required for the relief of the machine.
To these extended arms is suspended, by two rows of screw bolts, a stout Iron plate
called the turning plate with its front edge inclining to the floor, to which it is
regulated by having the bolts firmly affixed to the arms, the front edge of this
plate is straight about half the width on, the bolts are placed at about nine or ten
inches-apart in a line from the centre post to the wall--the first line of bolts is
placed in about the centre of the Plate, and the other close to the back edge, the

order to give additional action to the Malt, and also to give relief to the machine as
it moves on at the under side of the plate I may, if necessary, fix small rollers to
prevent the front edge coming in contact with the floor-a draught will be occasioned
by the hollow space under the plate in consequence of the opening under the bolts
at the back edge by the sinking of the concave parts, and this will serve to expedite
the drying of the Malt by allowing the steam to escape. I propose to have an
additional shaft lying in a horizontal direction with a small nut or pinion wheel to
correspond and work vertically with the large horizontal cogged wheel, one end of the
shaft working in the centre of the Standard, and the other extending up to, or through
the wall to be connected with the propelling machine.

An Improved Method and Means for Turning and Drying Malt and
Grain.
I JOHN REDGRAVE of 128 Princess Road Edgbaston Birmingham in the County
of Warwick Gentleman 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 Invention consists of a very simply constructed and inexpensive Machine
called "The Malt Turner" which has for its object an improved process in the mode
of turning over and drying of Malt and grain in one continuous regular uniform
manner from the time of its being deposited on the Floor of the drying Kiln until
the drying process is completed so that every grain of Malt may be regularly turned
and equally dried to any degree of temperature and to any color that may be required
whether Pale, Amber, Brown, high-dried or otherwise, and with such a soundness
and uniformity as will have the effect to retain its farinaceous and saccharine
properties.
Kilns for the reception of my Invention must be built upon a circular plan, but I
can apply it to any existing Kilns which may be of a square or oblong form by a
simple reconstruction in the interior arrangement of such Kilns.
I propose in the centre of the Floor of the Malt Kiln to fix an Iron Standard or
post to which will be attached the Machine consisting of a large horizontal cogged
wheel, and to this wheel are fixed one or more arms extending in the same direction
from the centre to the circumference of the Kiln and resting on a bearing or support
fixed on the side of, or in the wall whereon it travels by the aid of small rollers or
other equivalents which may be required for. the relief of the Machine, to these
extended arms is suspended, by two rows of screw bolts, a stout Iron plate called the
turning plate with its front edge inclining to the floor, to which it is regulated by
having the bolts firmly affixed to the arms, the front edge of this plate is straight
about half the width on, the bolts are placed at about nine or ten inches apart in a
line from the centre post to the wall- the first line of bolts is placed in about the
centre of the plate, and the other close to the back edge, the plate is bent or sunk in
a concave form at the back edge between the hinder bolts, in order to give additional
action to the Malt, and also to give relief to the machine as it moves on. At the
under side of the plate, I may, if necessary, fix small rollers to prevent the front
edge coming in contact with the floor. A draught will be occasioned by the hollow
space under the plate in consequence of the opening under the bolts at the back edge
by the sinking of the concave parts, and this will serve to expedite the drying of the
Malt by allowing the steam to escape-I propose to have an additional shaft lying in
a horizontal direction with a small nut or pinion wheel to correspond and work
vertically with the large horizontal cogged wheel, one end of the shaft working in
the centre of the standard, and the other extending up to or through the wall to be
connected with the propelling machine,

page_text: In order that my Invention may be more easily understood and carried into practice
I have appended hereto a large sized sheet of drawings upon which I have illustrated
one mode of constructing my Kilns.
Figure 1. is a broken off elevation with sufficient of the walls of the Kiln A broken
off in order to shew the Iron Standard B upon which the large horizontal cogged or
toothed wheel C. is supported or hung, and the shaft D is fixed, also the turning plate E
is seen in elevation in this figure.
Figure 2. is a plan of the Kiln complete.
Figure 3. is an end elevation of the turning plate E and
Figure 4. is a broken off side elevation of the turning plate E.
The Iron Standard B is fixed into the floor of the Kiln A at 1 by any suitable
means, such as screwing, bolting &c. Upon this Iron Standard B the large toothed
wheel C is mounted between two shoulders or bosses 62 and 13 so as to work easily-
Attached to the one arm of this toothed wheel C. by means of bolts, as for
example e¹ e and e³, is the turning plate E-this plate is made as follows, the top
plate is connected with the bottom by means of arms or rods e and these are
secured by means of nuts e both top and bottom as seen more clearly in Figures 3
and 4. It will be observed that the bottom plate is corrugated. at the back and
slightly concave at the front, this is to give additional action to the malt as herein-
before explained.
The large toothed wheel is actuated by the small toothed wheel F. which is fast
on to the Shaft D. this shaft is fixed into the Iron Standard B at d¹ and is
driven by means of a bolt upon the pulley G or by any such well known
equivalent.
The action is as follows-The Malt is placed in the Kiln A. and the Shaft D being
revolved communicates to the large tooth Wheel C. by means of the small tooth
wheel F thereby revolving the turning plate E. and this turning plate E turns over
and dries the Malt in one continuous regular uniform manner:
It will be understood that though I have shewn only one turning plate con-
nected to one arm of the wheel C. I could, if necessary, connect one to each of
the other arms.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is,
The improvement in the mode of turning and drying Malt and grain by means of
the apparatus constructed substantially as herein set forth.
