page_text: LETTERS PATENT to Charles Clarkson, of No. 9, Avery Row,
Lower Grosvenor Street, in the Parish of Saint George, Hanover
Square, Middlesex, for the Invention of "AN IMPROVED DUSTER OR
DUSTING BRUSH, PAINTING BRUSH, AND ALL OTHER DESCRIPTION OF
BRUSHES, THE HANDLE OF WHICH PASSES THROUGH THE CENTRE, AND THE
HAIR OR BRISTLES ARE BOUND OR TIED ROUND IT."
Sealed the 19th July 1853, and dated the 18th May 1853.
PROVISIONAL SPECIFICATION left by the said Charles Clarkson'
at the Office of the Commissioners of Patents, with his Petition,
on the 18th May 1853.
I, CHARLES CLARKSON, do hereby declare the nature of the said
Invention for "AN IMPROVED DUSTER OR DUSTING BRUSH, PAINTING BRUSH,.
AND ALL OTHER DESCRIPTIONS OF BRUSHES, THE HANDLE OF WHICH PASSES
THROUGH THE CENTRE, AND THE HAIR OR BRISTLES ARE BOUND OR TIED
ROUND IT," to be as follows:-
My Invention consists in cutting a groove round that part of the
handle of a brush that is close to the tops of the bristles, and then by
cutting a section from two opposite sides close to the groove I make

page_text: that part of the handle oval or elliptic, instead of circular as before.
I then take a circular plate or collar of the same circumference as the
outside of the bristles, in the centre of which an oval piece is cut out,
corresponding in size and shape to the grooved part of the handle.
I then put the plate or collar over the handle, and pass it down to the
groove, and by then giving it half a turn round two of the inner edges
of the plate become firmly inserted in the groove, by which means the
handle is prevented from becoming loose or falling out; the plate or
collar may be made of metal or other material, and fixed by a cement.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Clarkson in the Great Seal Patent
Office; on the 9th November 1853.

vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
DUSTER OR DUSTING BRUSH, PAINTING BRUSH, AND ALL OTHER DESCRIPTIONS.
OF BRUSHES, THE HANDLE OF WHICH PASSES THROUGH THE CENTRE, AND THE
HAIR OR BRISTLES ARE BOUND OR TIED. ROUND IT," upon the condition
(amongst others) that I, the said Charles Clarkson, by an instru

+

page_text: 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 imme-
diately after the date of the said, Letters Patent.
NOW KNOW YE, that I, the said Charles Clarkson, 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:
My Invention consists in fixing a plate of metal or other material
on the handle of a brush, known by the name of a duster or 'dusting
brush and painting brush, close to the top of the bristles, in such a
manner that the handle cannot fall through, and is done as follows:-
I cut a groove with a saw an eighth of an inch deep round that
part of the handle that is close to the top of the bristles; I then cut a
piece off of each of two sides of the handle lengthways, parallel to
each other, an eighth of an inch deep at the bottom part next to the
bristles, and tapering towards the top, rendering the handle flat or
elliptic instead of round as before, and leaving a groove or slot on on
each of its remaining sides. I then take a circular plate of metal or other
material of the same circumference as the brush at the top part of the
binding of the bristles, with an elliptic or oval-shaped hole pierced
through its centre of the same size and shape as the handle of the
brush at the bottom part after its two sides have been cut away. I
then pass the handle of the brush through the hole in the centre of the
plate, by which means I bring the plate flat on the top of the bristles;
I then turn the plate round till its two inside edges become inserted in
the two grooves or slots that are left in the handle for that purpose;
a small space will be left between the hole in the plate and the
flat part of the handle, which I fill up with putty or other cement,
by which means the plate is permanently fixed and the operation is
complete.
The object of this Invention is to prevent the handle of the brush
from falling through, an accident that commonly occurs to this
description of brushes.

page_text: What I claim as new in this Invention is, the plate itself, and the
method of its application.
In witness whereof, I, the said Charles Clarkson, have heretofore
set my hand and seal, this Ninth day of November, A.D., 1853.
CHARLES CLARKSON.
