Year: 1872

page_text: LETTERS PATENT to Bruce Tomlinson, of Asgarby, in the County of
Lincoln, Gentleman, for the Invention of "IMPROVEMENTS IN CORN
AND SEED DRESSING AND BLOWING MACHINES."
Sealed the 7th March 1873, and dated the 11th September 1872.
PROVISIONAL SPECIFICATION left by the said Bruce Tomlinson at
the Office of the Commissioners of Patents, with his Petition, on
the 11th September 1872.
I, BRUCE TOMLINSON, of Asgarby, in the County of Lincoln, Gentle-
man, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN CORN AND SEED DRESSING AND BLOWING MACHINES," to be as
follows:-
The improvements consist in delivering corn or seed from dressing
machines into sacks at either side of the machine without the use of an
elevator, and may be carried into effect as follows:-The corn is placed.
in the hopper and falls upon the riddle while being acted upon by the
blast from the fan in the usual way. After passing through the riddle
the corn next falls upon the screen which it is intended shall be inclined
to either side of the machine that may be desired at such an angle as to
cause the best corn to fall through a spout at a sufficient height from

page_text: the ground to allow it to fill a sack placed there for that purpose, the
screenings at the same time fall into a hopper, and may also pass thence
into a sack if desired.
Two brackets are fixed preferably on the inner side of the lower part
of the shoe, one of which brackets forms a rest for the upper end of the
screen, whilst the other one prevents the corn or seed from passing
through the spout above-mentioned without being properly screened.
The screen is preferably made of the same size as the riddles so that
any of the riddles can be used as a screen; by simply removing the two
riddles the machine can at once be converted into a blower.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Bruce Tomlinson in the Great Seal Patent Office
on the 10th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BRUCE
TOMLINSON, of Asgarby, in the County of Lincoln, Gentleman, send

NOW KNOW YE, that I, the said Bruce Tomlinson, 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 :—
+
The improvements consist in delivering corn or seed from dressing
machines into sacks at either side of the machine without the use of an
elevator, and may be carried into effect as follows:-The corn is placed
in the hopper and falls upon the riddle while being acted upon by the
blast from the fan in the usual way. After passing through the riddle
the corn next falls upon the screen which it is intended shall be inclined
to either side of the machine that may be desired at such an angle as to
cause the best corn to fall through a spout at a sufficient height from
the ground to allow it to fill a sack placed there for that purpose, the
screenings at the same time fall into a hopper, and may also pass thence
into a sack if desired.
Two brackets are fixed preferably on the inner side of the lower part
of the shoe, one of which brackets forms a rest for the upper end of the
screen, whilst the other one prevents the corn or seed from passing
through the spout above mentioned without being properly screened.
The screen is preferably made of the same size as the riddles so that
any of the riddles can be used as a screen; by simply removing the two
riddles the machine can at once be converted into a blower.
The accompanying Drawing will serve in further illustration of the
manner in which my Invention may be performed.
In witness whereof, I, the said Bruce Tomlinson, have hereunto set
my hand and seal, this Seventh day of March, in the year of our
Lord One thousand eight hundred and seventy-three.
