Year: 1874

page_text: LETTERS PATENT to Richard Copping, Corn Miller, of Apperley
Bridge, near Leeds, in the County of York, and James Walworth,
Machine Maker, of Bradford, in the aforesaid County, for the
Invention of "IMPROVED MACHINERY OR APPARATUS FOR PREPARING
WHEAT BEFORE GRINDING."
Sealed the 4th August 1874, and dated the 15th June 1874.
COMPLETE SPECIFICATION filed by the said Richard Copping and
James Walworth at the Office of the Commissioners of Patents,
.
with their Petition and Declaration, on the 15th June 1874;
pursuant to the 9th Section of the Patent Law Amendment Act,
1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, RICHARD
COPPING, Corn Miller, of Apperley Bridge, near Leeds, in the County of
York, and JAMES WALWORTH, Machine Maker, of Bradford, in the
aforesaid County, send greeting.
:
WHEREAS we are in possession of an Invention for "IMPROVED-
MACHINERY OR APPARATUS FOR PREPARING WHEAT BEFORE GRINDING," and have

page_text: petitioned Her Majesty to grant unto us, our executors, administrators,
and assigns, Her Royal Letters Patent for the same, and have made
solemn Declaration that we verily believe ourselves to be the first and
true Inventors thereof..
NOW KNOW YE, that we, the said Richard Copping and James
Walworth, do hereby declare that the following Complete Specification,
under our hands and seals, fully describes and ascertains the nature of
our said Invention, and the manner in which the same is to be per-
formed, reference being had to the Drawing hereto annexed and forming
part of this Specification, and to the figures and letters marked thereon,
that is to say -
This Invention consists in improved machinery or apparatus for
preparing wheat before grinding.
In the accompanying Drawing Figure 1 is a sectional side elevation of
our improved machinery or apparatus; Figure 2, side elevation; Figure:
3, front Elevation, and Figure 4, plan of the same.
.
A hopper for receiving the wheat, and when the wheat entering the -
same rises to a certain height it opens an inclined lid B fixed by hinges
C.to the shoot D, the lid B opening more or less according to the weight
of wheat supplied, giving an uniformity of feed through the whole :
length of the rollers E and F, this uniformity of feed is regulated by the
spring G fitted to the side of the shoot D, and acting on the under side
of the lid B causes an even pressure. The regulation of the feed gives
an equal wear and tear on the whole surface of the rollers E and F.
The wheat falls between the rollers E and F and is broken and prepared
ready to be ground by the mill stones; the space H is regulated by
means of the sliding pedestals I working in slides M; the roller F is sct
by means of the pedestals I which are kept to the required positions
by the stop screws J working in the brackets K and by the set nuts
L; these stop screws J act on the back of the sliding pedestals I, which
pedestals are kept from moving by means of the spring N pressing on
the plate O by which an equal pressure is given to both pedestals I;
the spring N is actuated by the screw P worked by the hand wheel Q,
the screw P works in a cross bearing piece R bolted to the frame-
work S of the machine or apparatus; a stop nut T is fitted to the screw
P; the spring N also prevents hard substances injuring the faces of the
rollers E and F as it will give, and move the pedestals I, and con-

sequently the roller F, allowing the hard substances to fall down the
shoot D; the roller E is fitted on the shaft U and works in the fixed
pedestals Y; the shaft U is actuated by the driving drum V, and the
roller F fitted on the shaft X is either driven by means of the spur
wheels W or by means of the friction of the grain passing between
them. The rollers E and F are made of chilled cast iron turned perfectly
true, and to the rollers are fitted scrapers K' fixed to the shoot D and
made with slot holes S', enabling the setting of the scrapers to the face
of the rollers.
The wheat broken and prepared is conveyed to the garners and
supplied to the mill stones as heretofore. By these means we produce
broader bran, less fine sharps, better colour of flour, and ground loftier,
giving less wear and tear on the mill stones.
Having now described the nature of our said Invention and the
manner of carrying the same into effect, what we claim is, the general
arrangement and construction of machinery or apparatus for preparing
wheat before grinding, substantially as herein-before described and
represented in the accompanying Drawing.
In witness whercof, we, the said Richard Copping and James
Walworth, have hereto set our hands and seals, this Thirteenth
day of June, in the year of our Lord One thousand eight hundred
and seventy-four.
