IMPROVEMENTS in Tube BrusheS, APPLICABLE IN PART TO OTHER BRUSHES
Year: 1874

page_text: LETTERS PATENT to Thomas Nash, of No. 134, Great Dover Street, in
the County of Surrey, Brush Manufacturer, for the Invention of
“IMPROVEMENTS in Tube BrusheS, APPLICABLE IN PART TO OTHER BRUSHES.”

Sealed the 4th June 1875, and dated the 5th December 1874.
PROVISIONAL SPECIFICATION left by the said Thomas Nash at the
Office of the Commissioners of Patents, with his Petition, on the
5th December 1874.
I, THOMAS NASH, of No. 134, Great Dover Street, in the County of
Surrey, Brush Manufacturer, do hereby declare the nature of my said
Invention for "IMPROVEMENTS IN TUBE BRUSHES, APPLICABLE IN PART TO OTHER
BRUSHES," to be as follows:-
The object of my Invention is the making of brushes for the cleaning
of tubes, flues, and some other similar purposes, so that the said brushes
shall possess in a greater degree the qualities of strength, elasticity, and
durability than those heretofore used. In addition, these brushes will
not clog in use, and are not acted upon injuriously by the fire, as is the

page_text: case with those ordinarily employed, while they are more economical in
first cost. They can also be used whilst the fire is in action, which
cannot be done with any other but the metallic ones, and even those are
more injuriously affected thereby than my improved ones.
I. My Invention consists firstly in the adaptation and use for brushes
of an improved Patent or otherwise cut cane, cut in such manner that it
consists chiefly of the bark or external portion, possessing to a very great
extent the qualitics of elasticity and rigidity. The cane before being
made up into brushes is also subject to other treatment, as will be herein-
after described.
II. My Invention consists secondly in the use of a new mode of
fastening the cane in the spiral brushes by means of metallic wires, or
ferrules, or bands, or cords of material incombustible or rendered partly
or wholly incombustible or not liable to be acted upon by fire. The
cane is placed between two or more wires, and is secured in such position
by means of smaller wires, or ferrules, cords, or bands, which are passed
round the external wires so as securely to retain the cane therein, after
which the spiral form is given to the brush. This mode of fastening
prevents the rapid destruction of the brush by the materials employed
loosening and.coming to pieces. This part of my Invention is applicable
to brushes of wire, bristles, or other similar material.
III. My Invention consists thirdly in the use of a solution to improve
the condition of the cane, and to prevent its combustion or burning.
This solution consists of oxide of soda and alum or their chemical equi-
valents mixed together in about equal parts. I steep therein the cane,
and I do so generally for about half an hour, but the time may be
varied in accordance with the nature of the cane under treatment.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Nash in the Great Seal Patent Office on
the 5th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
NASH, of No. 134, Great Dover Street, in the County of Surrey, Brush
Manufacturer, send greeting.

vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
TUBE BRUSHES, APPLICABLE IN PART TO OTHER BRUSHES," upon the condition
(amongst others) that I, the said Thomas Nash, my executors or admini-
strators, by an instrument in writing under my, 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

NOW KNOW YE, that I, the said Thomas Nash, 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, that is to say :-
·
The object of my Invention is the making of brushes for the cleaning
of tubes, flues, and some other similar purposes, so that the said brushes
shall possess in a greater degree the qualities of strength, elasticity, and
durability than those heretofore used. In addition these brushes will
not clog up in use, and are not acted upon injuriously by the fire, as is
the case with those ordinarily employed, while they are more economical
in first cost. They can also be used whilst the boilers are at work, which
cannot be done with any other but the metallic ones, and even these are
more injuriously affected thereby than my improved ones.
I. My Invention consists firstly in the adaptation and use for spiral
3 and other brushes of an improved Patent or otherwise cut cane, in all
cases cut in such manner that it consists chiefly of the bark or external
portion, possessing to a very great extent the qualities of elasticity and

page_text: rigidity. The cane is also subjected to other treatment, as will be
herein-after described.
II. My Invention consists secondly in the use of a new mode of
fastening the cane in the spiral brushes by means of metallic wires, or
ferrules, or bands, or cords of material incombustible or rendered partly
or wholly incombustible or not liable to be acted upon by fire. The
- cane is placed between two, four, or more wires, and is secured in such
· position by means of smaller wires, or ferrules, or cords, or bands, which
pass round the external wires so as securely to retain the cane therein.
With the external wires are formed the spiral of the brush. In order
more fully to illustrate this part of my Invention this Specification is
accompanied by a Sheet of Drawings, in which Figure 1 is a view of
one of my improved brushes; Figure 2 is a section at A, B, of Figure 1,
showing the position of the wire band or cord before being passed round;
Figure 3 is a section at A, B, Figure 1, showing the wire band or cord
bound around and in position, as is also shown at C, Figure 1. For the
wire band or cord, as shown, may be substituted ferrules of metal, as
herein-before mentioned. In all cases my mode of fastening prevents
the rapid destruction caused by the materials loosening, and the brush
coming to pieces. This mode of fastening is applicable to brushes of
wire, bristles, or any like material.
III. My Invention consists thirdly in the use of a solution to improve
the condition of the cane or other brush material, and to prevent its com-
bustion or burning. This solution consists of soda and of alum or their
chemical equivalents mixed together in about equal parts. I steep
therein the cane or other material, and I do so generally for about half
an hour, but the time may be varied in accordance with the nature of
the materials under treatment. This part of my Invention I apply also
for all kinds of brushes, whether spiral or otherwise.
Having now particularly described and ascertained the nature of my
said Invention, and in what manner the same is to be carried out, I wish
it to be particularly understood that what I claim as my Invention and
desire to secure by the herein-before in part recited Letters Patent is,—
Firstly. The adaptation and use for brushes of cane cut in a peculiar
manner, so that the exterior portion or bark alone is employed.
Secondly. The securing and mechanically fastening the cane within

page_text: the wires forming the spiral by means of metallic wires, or ferrules, or
cords, or bands of material incombustible or rendered partly so.
Thirdly. The use of a solution of soda and alum or their chemical
equivalents for the purpose of improving the condition of the cane or
other material and rendering it incombustible.
In witness whereof, I, the said Thomas Nash, have hereunto set my
hand and seal, this Fourth day of June, in the year of our Lord
One thousand eight hundred and seventy-five.
