page_text: LETTERS PATENT to William Henry Delamare, of 14, Clarence Place,
Hackney Road, in the County of Middlesex, for the Invention of "AN
IMPROVED MACHINE FOR PURIFYING' AND PEELING CORN."
PROVISIONAL,SPECIFICATION left by the said William Henry Delamare
at the Office of the Commissioners of Patents, with his Petition, on
the 13th September 1861.
I, WILLIAM HENRY DELAMARE, of 14, Clarence Place, Hackney Road,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "AN IMPROVED MACHINE FOR PURIFYING AND PEELING CORN," to be
as follows:-
My Invention has for its object the removal of the husks from corn and the
cleaning of the same by introducing it between the two roughened operating
surfaces of a revolving cylinder or cone and a stationary case or cover
inclosing the cylinder.
For this purpose the cylinder or cone is mounted on an inclined axle, and
is covered with punched iron so as to have a roughened external surface.
This cylinder or cone is capable of turning freely within the case or cover
which surrounds it, and which is concentric with the cylinder or cone and of
slightly increased diameter, so as to cause only a small space to intervene

page_text: between the two operating roughened surfaces. Tho case or cover is divided
longitudinally into two portions, one of which has one part of its concave
surface covered with files, another part with punched iron, and the remaining
part with wire gauze, the other or opposite portion being covered with wire
cards in one part of its length and wire gauze in the remaining part. But
the mode of arranging and combining the said roughened surfaces may be
varied. By this arrangement the corn fed into the machine will be drawn
in by the action of the revolving cylinder or cone and thrown on to the
different parts of the roughened convex and concave surfaces of the cylinder
and the case or cover respectively, by which operation .the husks will be
removed and the corn will be cleaned.
The corn is or may be further treated by means of another cylinder or cone
covered with brushes and revolving within a stationary case or cover of wire
gauze, a fan or blower being combined therewith, or one end of the first-
described revolving cylinder or cone may be covered with brushes for the
same purpose. The admission of the corn into the machine is regulated
by means of the ordinary fork or lever for throwing the strap from the fast
to the loose pulley through a lever or other suitable mechanism, which is
thus made to act on a valve leading into the passage through which the corn
is fed in...
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Delamare in the Great Seal Patent Office
on the 18th March 1862.

Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Henry Delamare, Her special license that I, the said
William Henry Delamare, my executors, administrators, and assigns, or such
others as I, the said William Henry Delainare, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of

page_text: Great Britain and Ireland, the Channel Islands; and Isle of Man, an Invention
for "AN IMPROVED MACHINE FOR PURIFYING AND PEELING CORN,"
the
upon
condition (amongst others) that I, the said William Henry Delamare, by an
instrument in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar nionths next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said William Henry Delamare, do hereby
declare the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference: being had to the Drawing hereunto annexed, and to
the letters and figures marked thereon (that is to say):-
My Invention of "An Improved Machine for Purifying and Peeling Corn"
has for its object the removal of the husks from corn and the cleaning of the
same by introducing it between the two roughened operating-surfaces of a
revolving cylinder or cone and a stationary case or cover inclosing the
cylinder.
For this purpose the cylinder or cone is mounted on an inclined axle, and is
covered with punched iron so as to have a roughened external surface. This
cylinder or cone is capable of turning freely within the case or cover which
surrounds.it, and which is concentric with the cylinder or cone and of slightly
increased diameter, so as to cause only a small space to intervene between
the two operating roughened surfaces. The case or cover is divided longi-.
tudinally into two portions, one of which has one part, of its concave surface
covered with files, another part with punched iron, and the remaining part
with wire gauze, the other or opposite portion being covered with wire
cards in one part of its length and wire gauze in the remaining part. But
the mode of arranging and combining the said roughened surfaces may be
varied. By this arrangement the corn fed into the machine will be drawn in
by the action of the revolving cylinder or cone and thrown on to the different
parts of the roughened convex and concave surfaces of the cylinder, and the
case or cover respectively, by which operation the busks will be removed and
the corn will be cleaned.
The corn is or may be further treated by means of another cylinder or
cone covered with brushes and revolving within a stationary case or cover of
wire gauze, a fan or blower being combined therewith, or one end of the
first-described revolving cylinder or cone may be covered with brushes for the
same purpose.. The admission of the corn into the machine is regulated by.

page_text: means of the ordinary fork or lever for throwing the strap from the fast to the
loose pulley through a lever or other suitable mechanism, which is thus made
to act on a valve leading into the conduit or passage through which the corn
is fed in.
Having thus stated the nature of the said Invention, I will proceed to
describe more particularly in what manner the same is to be performed, by
reference to the accompanying Drawings, in which are represented the parts
of apparatus above referred to.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows the interior of the stationary case; Fig. 2 shews the revolving
cylinder; Fig. 8 shews a twelve-sided drum covered with brushes; Fig. 4
shews the brushes as arranged on the drum; Fig. 5 is an elevation of the
apparatus complete, and Fig. 6 is an elevation of the drum covered with
brushes. In theso several Figures the same letters of reference indicate
corresponding parts.
a represents the surface covered with files of moderate cutting or reducing
power; b, the surface covered with punched iron; c, the wire gauze; d, the,
surface covered with wire cards; e, wire gauze.
The external surface of the cylinder shown at Fig. 2 is covered with
punched iron or other roughened metal. The grain intended to be cleaned is.
introduced through the conduit A. and conveyed forward by the archimedean
screw at B, whence it falls into the machino through the conduit C,.and
being drawn by the rotary movement of the cylinder it is successively, projected!
on to the files a, the wire cards d, and the punched iron b; the combined;
action of which has the effect of dotacliing from the grain all foreign matters.
and thus of cleaning it, the refuse being driven out. through the wire gauze
and through a spout D in connection with a fan or blower: The grain, is
afterwards submitted if necessary to the action of brushes, which by pressing
the grain against the stationary case complete the cleaning of the same.
In some cases the brushes alone may be sufficient for the cleaning: The
brushes, it will be seen on reference to Fig. 3, are fixed around as twelve-
sided drum, and on reference to Fig. 4 it will be seen that they are.
arranged in spiral lines, by which arrangement they serve to convey, the:
grain to the end of the apparatus: They may also be similarly arranged
if found desirable on one end of the cylinder instead of on a separate
drum; I prefer for the purpose to make the brushes of the material called
French whisks," the spiral arrangement thereof being equally applicable.,
The second apparatus shewn at Fig. 6' is also furnished with a fan or blower...

page_text: In order to facilitate and regulate the introduction of the corn or grain
into the screw conveyer B, and also to obviate the necessity for constant
attendance the lever, by means of which the driving strap is shifted on to the
fast or loose pulley, is employed to communicate with the aperture for the
admission of the corn or grain, so as to open or close it according as the
machine is started or stopped.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I. hereby declare that what I claim as of
my Invention is,―
First, the combination of files, punched iron, and metallic cards applied
to the cleaning of corn or grain, whether arranged in the manner herein-before
described or otherwise.
Secondly, the combination and arrangement of the parts of apparatus
herein-before described, whether the sides of the revolving cylinder be parallel
as represented or conical, and whether the cylinder be arranged to work
horizontally or vertically.
And, lastly, the adaptation of the lever for starting and stopping the machine
to the purpose of regulating the feeding of the corn or grain into the machine,
in the manner herein-before described.
In witness whereof, I, the said William Henry Delamare, have hereunto
set my hand and seal, this Thirteenth day of March, in the year of our
Lord One thousand eight hundred and sixty-two.
W. H. DELAMARE. (L.S.)
