IMPROVEMENTS IN APPARATUS TO FACILITATE THE WEIGHING OF CORN AND OTHER GRAIN
Year: 1872

page_text: LETTERS PATENT to Algernon Sydney Ayre, of High Street, Kingston-
upon-Hull, for the Invention of "IMPROVEMENTS IN APPARATUS TO
FACILITATE THE WEIGHING OF CORN AND OTHER GRAIN."
Sealed the 12th July 1872, and dated the 19th January 1872.
PROVISIONAL SPECIFICATION left by the said Algernon Sydney Ayre
at the Office of the Commissioners of Patents, with his Petition, on
the 19th January 1872.
I, ALGERNON SYDNEY AYRE, of High Street, Kingston-upon-Hull,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS TO FACILITATE THE WEIGHING OF CORN AND OTHER GRAIN," to be as
follows:-
The object of the Invention is to simplify the operations connected
with the weighing of corn and other grain.
In carrying out my Invention the vessel or receiver for the respective
quantities to be weighed is suspended upon one end of a lever, arm, or
balance, the other end of which is provided with the counterbalance

page_text: weight or equivalent of quantity, and until filled this vessel or receiver
rests under or against a passage for the flow of the matter to be weighed
from a chamber above. This passage is opened by a moving cover there-
from, so that as soon as this vessel or receiver becomes filled to an extent
such that the weight thereof is greater than that of the counterbalance
weight, the vessel or receiver begins to descend or move away from the
supply passage, when a catch which held the cover of that passage open
is released, and a spring or springs, or it may be weight, then at once
closes that cover over the passage, and stops the supply.
The bottom of the vessel or receiver is formed by preference of two
inclined surfaces, which are moveable, and held closed by jointed bars.
One end of each of these jointed bars is connected to a part of or a pro-
jection from the vessel or receiver, whilst the other end of it is connected
to the part to be opened. In the descent of the vessel or receiver these
jointed bars come each against a fixed bar or projection, by which the
two parts thereof are caused to turn upon their joints and the bottom is
opened, by which the contents of the vessel or receiver become at once
delivered therefrom, when the counterbalance weight causes the return
of the empty vessel or receiver back again into a position to be refilled,
the jointed bars at the same time coming against another or other bar or
stop, by which the rigidity of those bars is restored, and the bottom of
the vessel is closed. The cover to the supply passage may then be again
opened by an attendant, or such opening may be effected by the action
of a driver, or such like means, operated by an eccentric, crank pin, or

Office on the 19th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALGERNON
SYDNEY AYRE, of High Street, Kingston-upon-Hull, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of January, in the
year of our Lord One thousand eight hundred and seventy-two, in
the thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Algernon Sydney Ayre, Her
special licence that I, the said Algernon Sydney Ayre, my executors,
dministrators, and assigns, or such others as I, the said Algernon
Sydney Ayre, 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 APPARATUS TO FACILITATE THE WEIGHING OF CORN AND
OTHER GRAIN," upon the condition (amongst others) that I, the said
Algernon Sydney Ayre, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
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 Algernon Sydney Ayre, 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 thereof, that is to say :-
The object of the Invention is to simplify the operations connected
with the weighing of corn and other grain.
In carrying out my improvements the vessel or receiver for receiving
the respective quantities to be weighed is suspended upon one end of a
lever arm, frame, or balance, the other end of which is provided with

page_text: measuring or weighing box separately; and Figure 6 shows by trans-
verse section some of the parts more clearly than in other of the Figures.
In each of the views the same letters are employed to indicate corre-
sponding parts wherever they occur.
a, a, is the framing of the apparatus; b, b, the balance levers or beams,
which are connected together at their centre of motion by the tie rods c,
the ends c¹ of which are V formed on their under side and rest on the
stecl blocks d, carried by the brackets d¹. One end of each of these
beams is formed as shown to receive the V formed studs or supports f,
projecting from the opposite sides of the weighing box e, whilst the
opposite ends of those levers or beams 6 in like manner, by means of the
bar with formed ends ³, h³, support the rod and weight 9', which
may be changed or varied to correspond with that of the corn or other
grain to be weighed. The box e is fitted with flaps or shutters i, which
are hung upon hinges ³, and are balanced by the weight of the rods k
and parts connected therewith, or by weights applied thereto, so as to
have a tendency to close with their lower edges against the cross bar j.
Each of these flaps or shutters i is provided with an arm &³, by which it
is connected by pin joint ¹ to one end of a jointed rod k, and the upper
end of each of these jointed rods k is in like manner connected by pin
joint to an arm 7, affixed one on each opposite side of the box e. The
jointed parts k* of the rods k are provided with sliding pieces m, and
when the box e is empty or lighter than the counterbalance g¹ it is by
the weight g¹ borne upwards with its upper surface resting against the
under side of the platform q, and the arms k are then kept rigid by the
action of the sliding pieces m, which are suspended by links m³ from the
upper portion of the framing a, a, so as to rest over the joint * to hold
those rods rigidly, as though no joint existed at those parts, thus pre-
venting the opening of the flaps or shutters i, i; but so soon as the
weight of the quantity of corn or other grain to be weighed corresponds
with that suspended at g, the box e with the arms / begins to descend,
and in doing so the jointed portions of the rod i not only slide out from
the sliding pieces m, but the inclined sides m² of the pieces m are also acted
upon by the inclined projecting pieces o, o, projecting from the sides of the
box e, to force the pieces m and that part of each of the bars or rods k
outwards, by which the rigidity of the bars k is destroyed and the flaps
or shutters i at once fall open, discharging the contents of the box e into
a hopper or receiver beneath. The box e then again immediately ascends
.

page_text: of opening to deliver the measured quantities, and of resetting to receive
fresh quantities, and the registering of the operations, are self-acting,
substantially as described.
In witness whereof, I, the said Algernon Sydney Ayre, have here-
unto set my hand and seal, this Twelfth day of July, in the year
of our Lord One thousand eight hundred and seventy-two.
ALGERNON SYDNEY AYRE. (L.S.)
