Year: 1855

page_text: LETTERS PATENT to Samuel William Campain, of Deeping Fens, in the
County of Lincoln, Farmer, for the Invention of "IMPROVED MACHINERY
FOR FILLING CORN AND OTHER SACKS."
Sealed the 30th October 1855, and dated the 2nd May 1855.
PROVISIONAL SPECIFICATION left by the said Samuel William Campain
at the Office of the Commissioners of Patents, with his Petition, on the
2nd May 1855.
1, SAMUEL WILLIAM CAMPAIN, of Deeping Fens, in the County of Lincoln,
Farmer, do hereby declare the nature of the said Invention for "IMPROVED
MACHINERY FOR FILLING CORN AND OTHER SACKS" to be as follows:-
The chief object of this Invention is to facilitate the deposit of corn into
sacks in given quantities as it is discharged from the winnowing machine.
For this purpose I provide an endless chain of buckets or a screw or other
elevator, which, dipping into the vessel that receives the corn from the win-
nowing machine, will when set in motion raise it, and discharge it into an
elevated chamber provided with a discharge valve. This valve I connect with
a weighing machine by means of a rocking lever, or its equivalent, in such a
manner, that it shall be actuated by the rise and fall of the scales, and permit
of the discharge of the grain into the open mouth of a sack placed on one of

page_text: the scales immediately below the discharge aperture. When the sack has
received a given quantity of the grain, it will overbalance the weight in the
other scale, and by means of the lever arrangement, the valve will be caused
to fall and close the exit aperture.
When this arrangement of mechanism is applied to a winnowing machine, 6
I drive the elevator by means of a strap or chain from a pulley on the driving
shaft of the winnowing machine. It will be understood that this apparatus is
equally applicable to the depositing in sacks of a great variety of substances
in measured or determined quantities.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel William Campain, in the Great Seal Patent Oflice on
the 2nd November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
WILLIAM CAMPAIN, of Deeping Fen, in the County of Lincoln, Farmer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of May, in the year of our Lord One
thousand eight hundred and fifty-five, in the eighteenth year of Her reign,
did, for Herself, Her heirs aud successors, give and grant unto me, the said
Samuel William Campain, Her special licence that I, the said Samuel William
Campain, my executors, administrators, and assigns, or such others as I, the said
Samuel William Campain, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVED
MACHINERY FOR FILLING CORN AND OTHER SACKS," upon the condition (amongst
others) that I, the said Samuel William Campain, 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 Samuel William Campain, 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

page_text: following statement, reference being had to the Drawing hereunto annexed, and
to the letters and figures marked thereon (that is to say) :-
This Invention relates to a novel arrangement of apparatus for facilitating
the deposit of corn and other seeds into sacks in given quantities as it is
discharged from the winnowing machine, or when it is required to be measured
out from a bin or other receptacle.
In the accompanying Drawing, Fig. 1 shews, in partial sectional elevation,
my improved weighing apparatus applied to a winnowing machine; Fig. 2 is
a
plan view of the same with a portion of the case removed; and Fig. 8 is an
end view. This apparatus consists simply of a slanting frame a, which carries
at its upper and lower ends pullies b, b, round which an endless chain of
buckets c, c, pass for the purpose of raising the corn as it leaves the winnowing
machine and discharging it into an elevated chamber. This chamber is pro-
vided with an adjustable discharge valve and a shute for conducting the corn
to an open sack suspended from a weighing machine, which is connected with
and operates the discharge valve, as will be presently explained. At the
bottom of the frame a is a trough d, for receiving the winnowed grain as it
falls from the winnowing machine, and at the top of the frame is a chamber e,
to which the grain is raised by the endless chain of buckets c. These buckets
I prefer to make of tin (for lightness), and to connect them to a pair of
endless straps or bands, as shewn in plan view at Figs. 2 & 4. As, therefore,
these bands run over flanged pullies of a breadth merely sufficient for receiving
them, there will be free space for any grain that may be spilt falling down into
the trough d. f is the shute for conducting the corn from the chamber e to the
sack, and 9 is a slide valve for regulating the supply. To this valve is attached
an arm i, provided with ratchet teeth, into which a tumbler catch k takes, for
the purpose of keeping the valve open. This tumbler catch (see Fig. 3) is
held in position by means of a weighted bell-crank lever 1, which is supported
on a pin projecting from the side of the chamber e. The bell-crank lever is
furnished with a hooked termination, which bears on the tail end of the
tumbler catch, and thus causes the other end to sustain the weight of the
sliding cut-off valve. To the outer end of the bell-crank lever a pendent
rod m is jointed. The lower end of this rod passes through a bar n, attached
to an ordinary platform weighing machine, from which the open sack is sus-
pended. A screw thread is cut on the end of the pendent rod to receive an
adjustable nut or stop o, for the purpose to be presently explained. When
the apparatus is required to be put into operation, the attendant attaches it
to the winnowing machine by pins and links or rods p, p, and by means of a
band passing from the driving pulley of the winnowing machine to a driving

page_text: pulley on the axle of the upper pair of pulleys b, motion will be communicated
to the chain or band of buckets, which, by dipping into the trough or receptacle
for the seed from the winnowing machine, will clevate it and dischargo it into
the chamber e, whence it will fall down the shute into the open sack on the
weighing machine. When the sack has received a given quantity of seed,
equal to the weight placed in the opposite scale of the weighing machine, it
will overbalance that weight, and by this movement the barn will be caused
to strike the nut or stop o on the pendent rod, and thereby rock the bell crank
lever and release the tumbler catch k, which, being no longer able to sustain
the weight of the slide valve g, will allow it to fall, and close the discharge
opening for the grain. The filled sack is then to be removed and replaced by
an empty one, and the valve tumbler catch and bell crank lever being restored
to their former position, the filling of the sack will be resumed. For the
purpose of driving this machine, irrespective of the winnowing machine, I
propose to fit on to the frame speed wheels, and to drive them by a winch
handle, and thereby to render the machine independent of horse and steam
power. In lieu of the chain or band of buckets, I may find it convenient in
some cases to employ an archimedean screw as an elevator.
Having thus set forth the nature of my Invention of Improved Machinery
for Filling Corn and other Sacks, and explained the manner of carrying the
same into effect, I wish it to be understood that under the above in part
recited Letters Patent I claim, the arrangement of machinery, as above
described, which admits of being readily attached to and detached from the
ordinary winnowing machine, and of being used either in connection therewith
or irrespective of that machine.
In witness whereof, I, the said Samuel William Campain, have hereunto
set my hand and seal, the First day of November, in the year of our
Lord One thousand eight hundred and fifty-five.
