Street, Finsbury, London, Gentleman, for the Invention of." AN IMPROVED
APPARATUS FOR PURIFYING, MEASURING, AND WEIGHING GRAIN AND OLEA-
GINOUS SEEDS."
COMPLETE SPECIFICATION filed by the said Jean Louis Sicard at the
Office of the Commissioners of Patents, with his Petition and Decla-
ration, on the 26th October 1861, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN LOUIS.
SICARD, of Nice, France, and of 4, South Street, Finsbury, London, Gentle-
man, send greeting.
WHEREAS I am in possession of an Invention for. "AN IMPROVED APPA-
RATUS FOR PURIFYING, MEASURING, AND WEIGHING GRAIN, AND OLEAGINOUS SEEDS,"
and have petitioned Her Majesty to grant unto me, my executors, adminis-
trators, and assigns, Her Royal Letters Patent for the same.
NOW KNOW YE, that I, Jean Louis Sicard, do hereby declare that the
following Complete Specification under my hand and seal fully describes and
ascertains the nature of the Invention and the manner in, which the same is.

page_text: to be performed, reference being had to the accompanying Drawing, and to
the letters marked thereon, that is to say:-
My Invention consists, first, in the construction of an apparatus for
purifying, measuring, and weighing corn and oleaginous seed; secondly, in the
application to the lever of a Roman balance or steelyard of a ball for compen-
sating for the differences of weight caused by the variations of temperature in
the measures employed.
To render my Invention better understood I will now proceed. to describe
the same by referring to the accompanying Drawing, in which Figure 1 is a
view in perspective of the purifying apparatus; Figure 2 is the measuring and
weighing apparatus.
A, Figure 1, hopper in which the corn or oleaginous seed is introduced;
B, door for regulating the size of the opening in the hopper, whereby more or
less corn or seed as may be required may be admitted into the apparatus, such
door being raised or lowered by means of the lever B'; C, screen composed of
metallic wire gauze for purifying or cleaning the corn or seed by allowing the
escape of the dust and other impurities; D, tarred cloth or apron for receiving
the dust and impurities; E, pipe for conducting the dust and impurities into a
receptacle or barrel F, placed on the ground below the apparatus; G, oil cloth
for covering the screen; H, uprights or legs for supporting one end of the
apparatus; I, hooks for fixing the oil cloth; J, stopping door for preventing
the corn or seed from falling out, and raised by means of the lever J¹;
Y, stopping wedge; 1, purifying grating; 2, suspended grating; K, Figure 2,
opening through which the grain passes from the hopper A into the hopper A¹;
L,, L', Roman balances or steelyards provided with a .regulating ball or
weight; M, ball of sufficient weight for compensating for the differences of
weight which are caused in the measures by variations of temperature;
N, hook for raising and lowering the measures Q; O, joints of the hooks;
O¹, hook for supporting the steelyard; P, frame or door to allow the corn or
seed to fall down from the hopper A¹ into the measure below; Q, measure
constructed as shewn in the Drawing, of the capacity of about twenty-two-
gallons; X, wooden frame or support upon which the apparatus rests;
R, tramway upon which the carriage supporting the measures moves; S, stops
for the measures on the tramway; T, loop hole for ascertaining whether there
is sufficient quantity of seed in the hopper A to proceed with the measuring;
U, purifying grating; V, suspended grating; W, notification of the measuring ;
L", plummet for fixing the level of the apparatus; Q, levelling screw for
raising or lowering the apparatus for bringing close together the openings. in.
the lower door P and the measure Q...

in wire gauze C placed in an inclined. position, leaving behind them in their
passage the unripe seed, dust, and other impurities, and fall at the stopping
door J. All the refuse matters are received in the tarred cloth D, and caused
to pass by the inclined position of the cloth through the pipe E into the
barrel F. The oilcloth G, which covers the apparatus C, is attached to the
books I. When the door J is raised the seed falls through the orifice K into
the hopper A¹ of the measuring apparatus. This hopper is furnished, first, to a
certain height with a purifying grating U for retaining any particles larger
than the seed; secondly with two suspended gratings V, the holes of which are
opposite each other to facilitate the passage of the seed, the object of which is to
prevent the weight of the seed from causing the door P to give way or
impeding or stopping its opening. The lower suspended grating should be at
a distance of about two inches from the door P. The distance of the upper
suspended grating from the lower grating varies according to the weight of
the grain, that is to say, it should be nearer if the grain is heavy and farther
off if the grain is light. When, after inspection by means of the hole T, it is
thought fit to proceed with measuring the seed, the two measures are caused
to travel on the tramway, and the first is brought under the door P in such a
manner that their openings correspond exactly and nearly touch, which result
I obtain at need by raising or lowering the apparatus by means of four levelling
screws Q as herein-before described. I then open the door P, and the seed
falls from the hopper into the measure. When the measure is full I close
the door P, and I conduct the first measure along the tramway under the hook
of the balance L, and then weigh and empty the measure of its contents. At
the same time the second measure is placed under the door P at the place
which was occupied by the first, and I recommence the measuring operation.
When the second measure is filled it is brought to the steelyard or balance L'
on the other side of the apparatus, where it is in its turn weighed and emptied,
and so on successively by this forward and backward movement until the
weighing operation is completely terminated.
Having thus described the nature of my said Invention, and the manner
of carrying the same into effect, I would have it understood that I do not
confine myself to the precise details above laid down, as they may be
modified without affecting the main feature of my Invention; nor do I claim

page_text: the different parts of the machine taken separately, as the same are known;
but what I claim is,―
First, the general arrangement and construction of a machine for purifying,
measuring, and weighing corn and oleaginous seeds as herein-before described
and represented in the annexed Drawing..
Secondly, the application to the lever of a Roman balance or steelyard of a
ball for compensating for the differences of weight caused by the variations of
temperature in the measures employed, as herein-before described and repre-
sented in the annexed Drawing.
In witness whereof, I, the said Jean Louis Sicard, have hereunto set my
hand and seal, this Twenty-first day of October, in the year of our
Lord One thousand eight hundred and sixty-one.
