Year: 1852

page_text: LETTERS PATENT to Joseph Walker, of Dover, in the County of
Kent, Merchant, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR CRUSHING AND BRUISING MALT, GRAIN, AND SEEDS."-A con-
munication.
Sealed the 16th March 1853, and dated the 12th October 1852.
PROVISIONAL SPECIFICATION left by the said Joseph Walker at
the Office of the Commissioners of Patents, with his Petition,
on the 12th October 1852.
I, JOSEPH WALKER, of Dover, in the County of Kent, Merchant,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY FOR CRUSHING AND BRUISING MALT, GRAIN, AND SEEDS"
be as follows:-
I construct a cast iron roll fluted horizontally to-work against a fixed
concave segment fluted horizontally, with set screws attached for regui-
lating the pitch, according to the grain or seeds required to be worked;
above the roll and segment I construct a hopper with -proper feeding
shoots, to pass the seeds or grain to the roll for crushing.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Walker in the Great Seal Patent Office,
on the 12th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOSEPIL WALKER, of Dover, in the County of Kent, Merchant, send
greeting.
WHEREAS ITer most Excellent Majesty Queen Victoria, by Her
Letters Patent, caring date the Twelfth day of October, in the year
of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Walker, Her special licence
that I, the said Joseph Walker, my executors, administrators, and
_assigns, or such others as I, the said Joseph Walker, exccutors, admi-
nistrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the torm therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY
FOR CRUSHING AND BRUISING MALT, GRAIN, AND SEEDS," upon the condition
(amongst others) that 1, the said Joseph Walker, by an instrument in
-writing under my hand and scal, should particularly describe and ascer-
"
tain the nature of the said Invention, and in what manner the same was
to be performed, and cause the sanie to be filed in the Great Seal Patent
.Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Walker, do hereby
declare the nature of my said Invention, and in what manner the same
'is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the drawings
hereunto annexed, that is to say:
My Invention consists in crushing and bruising malt, grain, and
seeds by means of an iron or steel roller, fluted spirally or horizontally,
revolving against a fixed concave segment, also fluted horizontally, and
provided with set screws for regulating the gauge, according to the

page_text: grain or seeds to be operated upon, which are fed to the roller and
segment through a hopper. Figure 1, of the Drawings hereunto
annexed represents a longitudinal section of a machine constructed
according to my Invention. A, A, is the frame work; B, is the roller,
fluted across its surface either in a horizontal direction, as shown in the
detached view in Figure 2, or spirally, as indicated by the red line in
the same Figure. The roller is supported and turns in bearings or
brasses in the two side frames of the machine, and is caused to revolve
either by a crank handle, strap pulley, or other suitable gearing keyed
upon the shaft C. D, is a concave segment made of cast steel or cast
iron, case-hardened, and fluted horizontally. The flutes in both the
roller and segment are made similar to ratchet teeth, the faces of such
teeth being set in opposite directions to one another, as indicated in
Figure 1. The segment D, is capable of being adjusted to various
distances from the roller B, to suit the different grain or seeds to be
operated upon, for which purpose the front end of the segment is sup-
ported at each side upon the point of two set screws E, one only of
which is seen in the Figure,) which are tapped through the nuts E',
upon the cross bar E, of the framing. The screws E, are raised or
lowered by the hand lever a, passing through the head of the screw, and
by which the distance between the front of the segment and roller can
be regulated. The back part of the segment is carried up, as repre-
sented at D', and terminates in an eye b, to which one end of the lever
F, is attached. This lever is centred at c. and has attached to its
lower end the screw G, which is tapped through the nuts G', G¹,
whereby that end of the segment is also adjusted. H, is a fluted feed
roller driven by a strap and pulley I, from the pulley K, on the shaft C,
of the roller B. L, is the hopper for containing the seed or grain to
be crushed or bruised. This hopper is supported on the frame work A,
by the stays M, M. The under surface of the side M', of the hopper
has attached to it a slide or valve N, for regulating the feed of the
seed or grain to the rollers B, and segment D; the slide is regulated
by means of the screw N³, tapped through the nut N2, fixed to the
slide N. N³, N³, are guides for the screw N¹.
And having now described the nature of my said Invention, and the

page_text: manner in which the same is to be performed, I declare that I-claim
the crushing and bruising of malt, grain,. and seed by means of a
fluted roller working in conjunction with a fluted segment, and provided
.with adjusting screws, feeding apparatus, and hopper, in the manner
herein-before described and represented in the Drawings hereuïto
annexed.
In witness whereof, I, the said Joseph Walker, have hereunto
set my hand and seal, this Ninth day of April, One thousand
eight hundred and fifty-three.
JOSEPH WALKER. (L.S.)"
