page_text: LETTERS PATENT to Victor Pernollet, Engineer, of 43, Broad Street,
Golden Square, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SORTING OR SEPARATING WHEAT AND OTHER GRAIN PROM
DIFFERENT KINDS OF GRAIN, AND FOR SEPARATING OR REMOVING EXTRANEOUS
Sealed the 17th August 1854, and dated the 21st February 1854.
PROVISIONAL SPECIFICATION left by the said Victor Pernollet at the
Office of the Commissioners of Patents, with his Petition, on the 21st
February 1854.
We, ROSSIGNOL & CROOK, on behalf of VICTOR PERNOLLET, Engineer, 43,
Broad St., Golden Sq., do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SORTING OR SEPARATING
WHEAT AND OTHER GRAIN FROM DIFFERENT KINDS OF GRAIN, AND FOR SEPARATING OR
REMOVING EXTRANEOUS MATTERS FROM WHEAT AND OTHER GRAIN," to be as
follows:-
This Invention consists in constructing cylindrical or other shaped vessels,
with different sizes, and shapes of holes or openings, in the substance or
materials which form their sides or exterior, and in mounting such vessels
upon an inclined shaft or axis, whereby a rotary motion may be communi-
cated to them.

page_text: The following is an illustration of the manner in which it is intended to
perform the Invention. A cylindrical vessel is formed of perforated sheet tin
plate, fixed upon a series of metal rings for keeping it in form, and the
cylinder so constructed is mounted on a shaft running through it, which is
supported at both ends in suitable frame work, one end of the shaft being pro-
vided with a winch for turning it. A hopper or funnel is provided at the
upper end of the cylinder, into which the grain intended to be operated upon
is placed, and from which it is conducted into the cylinder through one of its
ends. The perforations of the cylinder are arranged in longitudinal series;
firstly a band or zone, of one size or shape, then another band or zone, and so
on; and underneath the different perforations of the series are separate funnels
or receptacles for the grain passing through each respectively. Stones and
extraneous matters larger than any of the perforations fall out at the lower end
of the cylinder. Perforated zinc, sheet iron, or any other suitable sub-
stance or material, may be substituted for the perforated tin plate of the
cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Victor Pernollet in the Great Seal Patent Office on the 21st
August 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VICTOR
PERNOLLET, of 43, Broad Street, Golden Square, in the County of Middlesex,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of February, in the year of our
Lord One thousand eight hundred and fifty-four, in the seventeenth year of
Her reign, did, for Herself, Ier heirs and successors, give and grant unto me,
the said Victor Pernollet, Her special licence, that I, the said Victor Pernollet,
my executors, administrators, and assigns, or such others as I, the said Victor
Pernollet, 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 Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR SORTING OR SEPARATING WHEAT AND OTHER GRAIN FROM DIFFERENT
KINDS OF GRAIN, AND FOR SEPARATING OR REMOVING EXTRANEOUS MATTERS FROM
WHEAT AND OTHER GRAIN," upon the condition (amongst others) that I, the said

page_text: Victor Pernollet, 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 months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Victor Pernollet, 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, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
My Invention consists in constructing cylindrical or other shaped vessels
with different sizes and shapes of holes or openings in the substance or
materials which form their sides or exterior, and in mounting such vessels
upon an inclined shaft or axis, whereby a rotary motion may be communicated
to them.
It is intended to perform the operation by means of a cylindrical vessel
formed of perforated sheet tin plate, fixed upon a series of metal rings for
keeping it in form, and the cylinder so constructed mounted on a shaft passed
through it, which is supported at both sides in suitable framework, one end of
the shaft being provided with a winch for turning it. A hopper or funnel is
provided at the upper end of the cylinder, into which the grain intended to be
operated upon is placed, and from which it is conducted into the cylinder
through one of its ends. The perforations of the cylinder are arranged in
longitudinal series; firstly a band or zone of one size or shape, then another
band or zone having perforations of another size size or shape, and so on.
Underneath the perforations of the several series are separate funnels or
receptacles for the grain passing through each zone respectively. Stones and
extraneous matters larger than any of the perforations fall out at the lower
end of the cylinder. Perforated zinc, sheet iron, or any other suitable sub-
stance or material, may be substituted for the perforated tin plate of the
cylinder.
Fig. 1 of the Sheet of Drawings hereunto annexed represents a side eleva-
tion of a machine constructed according to my Invention; Fig. 2, an end
elevation; and Fig. 3, a transverse vertical section of the same. A is the
separator, placed nearly in a horizontal position, and sustained by a suitable.
framework B, B. It is mounted on a shaft C, which is free to rotate in
suitable bearings D, D, supported by either end frame, and to which a rotatory
motion is communicated by hand, by the winch handle E, or it may be by
power, by means of the fast and loose pullies F, F; two light wheels G, G,

page_text: carry the separating drum or cylinder, and are situate at the points 1; 2, and
having their periphery exterior of the drum, so as to leave a clear surface on
the inside. H, I, K, L, are the zones or bands, each perforated with holes of
different sizes and shapes, regulated according to the character of the grain to
be cleaned or separated. M is a hopper mounted on standards m, m, from
the frame B, into which the grain is placed and supplied to the machine, the
supply being regulated by means of the sluce N, and so as to permit no more
to pass than can be properly treated by the machine. It will be observed that
the drum or separator A is a little inclined, the one end being lower than the
other, so that anything introduced at the highest end during the rotation of
this drum will gradually traverse the length of the cylinder, by reason of its
being partially carried round by the drum and falling back in the opposite
direction, and at an incline to the transverse plane of the drum, and thereby
attaining a lower level. If the grains introduced be too large to pass through
any of the perforations, they will pass out at the lowest end of the drum, and
others smaller will pass through the perforations according to their size and
character. The incline of the drum is about one in forty, which I find keeps
the grain the proper length of time under operation, when the drum is driven
at the rate of ten revolutions per minute, which I believe to be the best
velocity for the purpose; but I incline the drum more or less, according to the
amount of cleaning required and the time necessary to keep the grain under
operation to effect it. The upper end of the drum A has an inner flange or
rim O, to prevent the grain running out at that end; the supply pipe P
of the hopper being bent, so as to deliver the grain sidewise close to the
flange O.
For cleaning wheat, the perforations of zone H consist principally
of small narrow slits, which permit small thin seed and dust to pass out while
the whole is being manipulated therein. The corn, passes slowly thence into
the second zone or belt I, where round grain and larger extraneous matters pass
out, and thence to the zone K, where large grains and wheat pass out, thence
to zone L, where all the good wheat passes through, separated from extraneous
matters, while particles larger than wheat pass out at the end of drum, and
are conducted away by spout R. The several kinds of grain and wheat are
received separately in hoppers H', I', K', and L', placed below, and may be
conducted thence by spouts to any larger receptacle, as shown in dotted line.
When large quantities of grain are to be cleaned it may be advisable to con-
duct the grain from a larger receptacle into the hopper M, by a spout, as at S.
It is not essentially necessary that the separating drum should be truly
cylindrical, as a polygonal figure will answer the purpose.
The size and shape and arrangements of the perforations will necessarily

page_text: vary, according to the grain to be cleaned or separated, that represented being
intended for wheat, the perforations in zones K, L, being just large enough
for the grains to pass through easy, while the perforations in H and I are too
small to permit the passage of wheat grains.
Having described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I claim the arrangement
and construction of machine, substantially as described, for the purpose of
separating wheat and other grain from different kinds of grain, and for
separating other extraneous matters from wheat and other grain.
In witness whereof, I, Victor Pernollet, have hereunto set my hand and
seal, this Twenty-first day of August, in the year of our Lord One
thousand eight hundred and fifty-four.
VICTOR PERNOLLET. (L.B.)
