IMPROVEMENTS IN THE CONSTRUCTION AND PRODUCTION OF PROVISIONAL SPECIFICATION
Year: 1872

page_text: LETTERS PATENT to Thomas Harrison, of Burton Road, in the City
of Lincoln, Agricultural Implement and Machine Maker, for the
Invention of "IMPROVEMENTS IN THE CONSTRUCTION AND PRODUCTION OF
PROVISIONAL SPECIFICATION left by the said Thomas Harrison at the
Office of the Commissioners of Patents, with his Petition, on the
10th January 1872.
I, THOMAS HARRISON, of Burton Road, in the City of Lincoln,.
Agricultural Implement and Machine Maker, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION AND
PRODUCTION OF DRILLS OR DISTRIBUTORS FOR MANURE AND ALSO FOR DISTRIBUTING
SEEDS," to be as follows:-
This Invention has for its object improvements in the construction and
production of drills for distributing corn, seed, and manure, and pre-
venting superphosphates or other manures from working to a paste when

page_text: drilled in a damp state, and thereby causing an uneven delivery of corn,
seeds, and manure.
These improvements ensure an even delivery of damp superphosphates
or other manures as well as those of corn or seeds, also avoiding the
necessity of having a box bottom consisting of board, iron, malleable or
other convenient materials as in the case of ordinary drills.
These my improvements are less liable to breakage, and they do their
work in a superior manner.
To carry out my improvements the drills are so constructed and pro-
duced as to feed on or near the top or centre of the roller or manure-
distributing barrel, and at once delivers the superphosphates or other
manures falling upon it, thus preventing all friction or rubbing of the
manures, which invariably works them to a paste and causes uneven
delivery in ordinary drills.
My drills are so constructed that the roller or distributing barrel is
always exposed to sight and is accessible at any time to the man in
charge, the roller or distributing barrel forming the bottom or lower part
of the box, and entirely avoiding the necessity of taking the barrel out
to clean it after using damp manures as have heretofore been used, and
by not having a box bottom it prevents the manure or any other hard a
substance from getting wedged between the roller or barrel and the box
bottom causing a breakage.
By ensuring an even delivery of manures their value is increased, for
if placed on irregularly the strong manures would in places injure or
utterly destroy the corn or seed. But with these my improvements it
greatly improves their growth, ensures better crops and of superior
quality, and prevents the stoppage of corn or seed when conveyed down
the same spout to the root of the plant.
filed by the said Thomas Harrison in the Great Scal Patent Office on 30
the 9th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HARRISON, of Burton Road, in the City of Lincoln, Agricultural
Implement and Machine Maker, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth 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 successors,
give and grant unto me, the said Thomas Harrison, Her special licence that
I, the said Thomas Harrison, my executors, administrators, and assigns,
or such others as I, the said Thomas Harrison, my exccutors, adminis-
trators, 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, usc, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
"IMPROVEMENTS IN THE
Islands, and Isle of Man, an Invention for
CONSTRUCTION AND PRODUCTION OF DRILLS OR DISTRIBUTORS FOR MANURE AND
ALSO FOR DISTRIBUTING SEEDS," upon the condition (amongst others) that
I, the said Thomas Harrison, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, 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 Thomas Harrison, 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, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say:―
This Invention has for its object improvements in the construction and
production of drills for distributing corn, seed, and manure, and pre-
venting superphosphates or other manures from working to a paste when
drilled in a damp state, and thereby causing an uneven delivery of corn,
seed, and manure.
These improvements ensure an even delivery of damp superphosphates
or other manures as well as those of corn or seeds, also avoiding the
necessity of having a box bottom consisting of board, iron, malleable
or other convenient materials as in the case of ordinary drills.
These my improvements are less liable to breakage, and they do their
work in a sunerior manner.

page_text: To carry out my improvements the drills are so constructed and pro-
duced as to feed on or near the top or centre of the roller or manure-
distributing barrel, and at once delivers the superphosphates or other
manures falling upon it, thus preventing all friction or rubbing of the
manures, which invariably works them to a paste and cause uneven
delivery in ordinary drills.
My drills are so constructed that the roller or distributing barrel is
always exposed to sight, and is accessible at any time to the man in
charge, the roller or distributing barrel forming the bottom or lower part
of the box, and entirely avoiding the necessity of taking the barrel out
to clean.it after using damp manures as have heretofore been used, and
by not having a box bottom it prevents the manure or any hard sub-
stance from getting wedged between the roller or barrel and the box
bottom causing a breakage.
By ensuring an even delivery of manures their value is increased, for 1
if placed on irregularly the strong manures would in places injure or
utterly destroy the corn or seed. But with these my improvements it
greatly improves their growth, ensures better crops and of superior
quality, and prevents the stoppage of corn or seed when conveyed down
the same spout to the root of the plant.
Having thus set forth the nature of the said Invention I now proceed
with reference to the accompanying Drawings to describe more fully the
manner of nerforming the same

finger point frame.
Figure 8 represents a front elevation of the grooved worm.
Figure 9 exhibits cannisters made of tin, iron, or other convenient
metal, and placed at the sides of the revolving discs.
Figure 10 shows the delivery pipe.
Figure 11 represents revolving discs, the cups on the side of which
delivers the corn or seed into the delivery pipe Figure 10.
I should here mention that in carrying out my Invention I sometimes
prefer to exclude the use of the roller or barrel entirely, and a dis-
tinguishing feature of this my Invention is that of avoiding the use of
the box bottom, thus allowing the manures to pass through the box
without being carried out by the roller or barrel, thereby preventing
undue friction or the working of the manures to a paste.
Having now described the nature of the said Invention, and the
manner of performing the same, I declare that what I claim is,―
First. Improvements in the construction and production of drills or
distributors for corn, seeds, and manure, and preventing superphosphates
or other manures from working to a paste when drilled in a damp state,
and without the employment of the usual box bottom, and also for the
irregular parrallel motion seen in Figure 6.
Second. The general arrangement and combination of parts con-
stituting the machinery or apparatus substantially as herein-before
described and set forth.
In witness whereof, I, the said Thomas Harrison, have hereunto set
my hand and seal, this Second day of July, in the year of our
Lord One thousand eight hundred and seventy-two.
