Year: 1870

page_text: LETTERS PATENT to Charles Dening and Samuel Henry Dening, of the
Firm of C. Dening and Company, of Chard, in the County of
Somerset, Iron Founders and Implement Manufacturers, for the
Invention of "AN IMPROVEMENT IN BRUSHES APPLIED. TO DRILLS FOR
SOWING ALL KINDS OF CORN AND SEED."
Sealed the 16th August 1870, and dated the 25th February 1870.
PROVISIONAL SPECIFICATION left by the said Charles Dening and
Samuel Henry Dening at the Office of the Commissioners of Patents,
with their Petition, on the 25th February 1870.
We, CHARLES DENING and SAMUEL HENRY DENING, of the Firm of
C. Dening and Company, of Chard, in the County of Somerset, Iron
Founders and Implement Manufacturers, do hereby declare the nature of
the said Invention for "AN IMPROVEMENT IN BRUSHES APPLIED TO DRILLS FOR
SOWING ALL KINDS OF CORN AND SEED," to be as follows:-
According to our improvement in brushes used for regulating the
supply of seed in drills we secure the hair forming the brush between
two discs riveted or otherwise, connected together on a spindle so as to

page_text: clamp and retain the hairs, the outer ends of which present a continuous
even surface ensuring a regular deposit of the grain and preventing
waste. The discs are of metal dished on their inner surfaces to receive
the ends of the hairs, and placed face to face with the hair between
them, the edges of the discs serving to compress and retain the hair.
The hair radiates from the brush spindle equally on all sides, and
presents a continuously acting cylindrical surface as above mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Dening and Samuel Henry Dening in the
Great Seal Patent Office on the 25th August 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
DENING and SAMUEL HENRY DENING, of the Firm of C. Dening and
Company, of Chard, in the County of Somerset, Iron Founders and
Implement Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of February, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Charles Dening and Samuel Henry Dening,
Her special licence that we, the said Charles Dening and Samuel
Henry Dening, our executors, administrators, and assigns, or such others
as we, the said Charles Dening and Samuel Henry Dening, our exe-
cutors, 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 "AN IMPROVEMENT
IN BRUSHES APPLIED TO DRILLS FOR SOWING ALL KINDS OF CORN AND SEED," upon
the condition (amongst others) that we, the said Charles Dening and
Samuel Henry Dening, our executors or administrators, by an instrument
in writing under our, 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.

page_text: NOW KNOW YE, that we, the said Charles Dening and Samuel
Henry Dening, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the Sheet of Drawings hereunto annexed, and to the
letters and figures marked thereon (that is to say) :—
According to our improvement in brushes used for regulating the
supply of seed in drills we secure the hair forming the brush between
two discs riveted or otherwise connected together on a spindle so as to
clamp and retain the hairs, the outer ends of which present a con-
tinuous even surface ensuring a regular deposit of the grain and
preventing waste. The discs are of metal dished on their inner surfaces
to receive the ends of the hairs and placed face to face with the hair
between them, the edges of the discs serving to compress and retain the
hair. The hair radiates from the brush spindle equally on all sides,
and presents a continuously acting cylindrical surface as above.
Figures 1 and 2 are external views of our improved brush for regu-
lating the supply of seed in drills, and Figure 3 a section of the same
taken on line 1-2, Figure 2.
The brush is formed in two parts or discs of metal or wood A, A,
bolted or otherwise connected together face to face with the hair B
The faces of discs A are dished or
clamped between them as seen.
hollowed, as shown in the section Figure 3, to allow room to receive the
ends of the bristles or hairs which are firmly compressed and retained by
the edges of the discs. The outer ends of the hair radiate from the
edges of of the discs equally on all sides and present a continuous even
surface as shown for ensuring a regular delivery of the grain and for
preventing waste. To make a brush the discs are mounted on a vertical
spindle, and the hair or bristles previously cut to one length are inserted
between them with their inner ends abutting against the spindle from
which they radiate. When a sufficient quantity is inserted the discs arc
or drawn together and secured by the screws C, or they may be riveted if
of metal. The circumference or working face of the brush may after-
wards be trimmed to a uniform surface if necessary, and the brush may

page_text: be removed from the spindle on which it was mounted as above
mentioned to be keyed on the brush spindle D of the drill.
Having described the nature of our Invention, and the manner of
performing the same, we declare that what we claim as our In-
vention to be protected by the herein-before in part recited Letters
Patent is -The improved construction of brush for use in corn and seed
drills herein-before described and illustrated in the Drawings annexed,
as and for the purposes specified.
In witness whereof, we, the said Charles Dening and Samuel
Henry Dening, have hereunto set our hands and seals, this
Twenty-second day of August, in the year of our Lord One
thousand eight hundred and seventy.
