1, ROBERT ADDIS of London Brush Works, London Fields, in the County of
Middlesex, Brush Manufacturer do hereby declare the nature of this invention to
be as follows:-
The invention relates to improvements in or connected with tooth, nail, and other
brushes, and has for its object to fasten the bristles in the stock or back in a more
secure manner than heretofore.
For this purpose, in addition to the ordinary means of securing the bristles with
relation to the stock or back, a number of holes are drilled transversely of the
stock or back, either from each side thereof or from one side to the other, one hole
corresponding with each row of bristles and so arranged that it will intersect the
sanie.
Into these boles is introduced by running it therein or otherwise, shellac or other
suitable cement which intermingles with the bristles and when set forms a more or
less solid key to bold the same in position.
In lieu of filling the transverse holes with cement to fasten the bristles in place
wood, bone, wire, or other pegs or other means may be substituted therefor.
By the means herein before described the bristles are more firmly secured and
consequently less liable to work out than heretofore.

COMPLETE SPECIFICATION.
Improvements in or connected with Tooth, Nail, and other Brushes.
I, ROBERT ADDIS of London Brush Works, London Fields in the County 'of
Middlesex, Brush Manufacturer do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:
The invention relates to improvements in or connected with tooth, uail, and other
brushes, and has for its object to fasten the bristles in the stock or back in a more
secure manuer than heretofore.
For this purpose, in addition to the ordinary means of securing the bristles with
relation to the stock or back, a number of holes are drilled transversely of the
stock or back, either from each side thereof, or from one side to the other, one hole
corresponding with each row of bristles and so arranged that it will intersect the
same.
Into these holes is introduced by running it therein or otherwise, shellac or other
Prici

page_text: suitable cement which intermingles with the bristles, and when set,forms, a more or
less solid key to hold the same in position.
:
In lieu of, or in addition to filling the transverse holes with cement to fasten the
bristles in place wood, bone, wire or other pegs or other means may be substituted
therefor.
And in order that the said invention may be more clearly understood and
readily carried into effect I will proceed aided by the accompanying drawings more
fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a tooth brush constructed according to the present
invention.
Figure 2 is a sectional side view of part thereof.
Figure 3 is a sectional plan of part thereof..
Figure 4 is a transverse section thereof with some parts omitted.
Figure 5 represents a portion of Figure 2.
Figure 6 is an end view partly in section representing a slight modification; and.
Figure 7 is a vertical longitudinal section of part thereof.
In the several figures in which like parts are indicated by similar letters of
reference Figures 2, 3, 4 and 6 are drawn to an increased scale with respect to
Figure whilst Figures 5 and 7 are drawn to a still further increased scale..
Referring to Figures 1 to 5 a represents the stock or back of the brush,
b represents the bristles, c-represents the lengths of wire which are passed through
the loops of the knots or bunches of b: istles b and by the aid of which, the latter
are drawn into position whilst a¹ represents the slits through which the wire is
passed and which are afterwards filled in with cement al in the usual way..
In brushes constructed in the manner heretofore adopted there is a liability for
the bristles b to break at the point where they are bent around the wire c, and
thus become detached from the stock or back a, or for the wire c to become oxidized
and break with a similar result, and the object of the present invention is to
remedy this defect.
According to the present invention in addition to the ordinary means therein-
before described of securing the bristles b with relation to the stock or back a
a number of holes á are drilled transversely of the stock or back a from one side
to the other; or-they might be drilled from either side, thereof, one hole a' corre-
sponding with each row of bristles b and intersecting the same.
Into the transverse boles a' is introduced preferably by running it therein,
shellac or other suitable cement d which intermingles with the bristles b at the
butts or loops of the knots or bunches and adheres thereto, so that when set it
forms a more or less solid key to bind the knots or bunches in position in the back
E or stock a whilst at the same time it secures each individual bristle.
After the cement d has been introduced into the transverse holes a' in the
manner hereinbefore described the extreme ends of the holes a areifinally filled in
with-a-stopping composed of shellac and zine white or other suitable material in
order to give a-finish to the article.
In the example given at Figures 6 and 7 in addition to filling or partially filling
the transverse holes a with fluid shellac or the like in order to fasten the bristles b
in place, wood, bone, wire or other pegs or rods e are inserted into the transverse
holes a aud passed through the loops of the knots or bunches of bristles 6 or when
employing the pegs or rods e the cement key d may if desired be dispensed with.
It will be obvious that any other suitable means than those hereinbefore
described may be introduced into the transverse holes a and through the loops of
the knots or bunches of bristles 6 in order to key the same in position..
Although the invention is shown and described in connection with a tooth brush
it will be understood that it is equally applicable. to nail, hair and like brushes.

By the means herein before described the bristles are more firmly secured in

page_text: the stock or back of the brush and consequently are less liable to work out than
heretofore.
Having now particularly described and ascertained the nature of the said inven--
tion and in what manner the same is to be performed I declare that what [
claim is:-
1. In a brush the combination of a stock or back formed with a number of
transverse holes coincident with the rows of bristles and cement or other keys
introduced into such holes so as to pass through the loops of the knots or bunches.
of bristles substantially as herein shown and described and for the purpose state...
2. In a brush the combination of a stock or back formed with a number of
transverse holes coincident with the rows of bristles, and a filling of cement ru
into said holes whilst in a liquid state in such manner as to intermingle with the
bristles substantially as herein showu and described and for the purpose stated.
3. In a brush the combination of a stock or back formed with a number of
transverse holes coincident with the rows of bristles, a filling of cement run into.
such holes whilst in a liquid state, in such manner as to intermingle with the
bristles, and a wood, bone, or other peg or key inserted into each transverse hole so
as to pass through the loops of the knots or bunches of bristles, substantially as.
herein shown and described and for the purpose stated.
Dated this 11th day of December 1896.
