PROVISIONAL SPECIFICATION:
Improvements in or relating to Brushes, more especially to Tooth
Brushes.
•
I, ROBERT GLENDOUNING HUNTER, of 137, Avenue Road, Southampton, in the
County of Hants, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to brushes more especially to tooth brushes.
In tooth brushes now ordinarily made the hairs or bristles are set in the stock
at right angles to same, thus when in use the bristles are caused to more or less
lie over in the opposite direction, in a line with the stock or handle, to that in
which the brush is moved backwards and forwards.
The object of my said invention is to fit and arrange the bristles on the stock
of brush so that in use, whatever direction the brush is moved lengthways, some
at least of the bristles shall work at right angles or approximately so to the surface
upon which the brush is used.
With this object in view I provide that some of the bristles in each row, lengthways
of the brush, shall lie in a more or less sloping direction; of two adjacent bristles
one will be sloped in one direction lengthways of the stock, and the other bristle in
the opposite direction the two bristles thus crossing each other, forming the
figure X; for instance, the first and last bristle of each respective row of same,
lengthways of the stock, may be fixed in the stock at right angles to same and the
intermediate bristles would be placed as described forming the figure ✗; and at
right angles to the stock respectively.
Thus in brushes made according to my invention, in whatever direction they are
used lengthways of the stock some of the bristles will be working at right angles,
or approximately so, to the surface of the teeth thereby more effectually cleansing
game.
For the purpose of more effectively cleaning the back of the teeth I make a brush,
according to another form or modification of my invention, as follows:-
On one end of a stock or handle I form a short clump on either the top or bottom
side of same, and fit bristles in the two sides of the said clump in similar manner
as hereinbefore described, in using this brush on one side of the mouth one side of
the brush will be used, and the other side of brush for the opposite side of the
mouth. The bristles of brush being situated either above or below the stock or
handle allow of the bristles to more effectually reach and clean the lower part of the
teeth at the back of same.
I may however if preferred arrange for the bristles to be attached direct on each
side of the end of the stock or handle without forming a clump on the top or bottom
side of same, in' manner aforesaid.
I may also if preferred arrange that the two forms of brushes shall be fitted to
one and the same stock or handle.
I have described my improvements as applied to tooth brushes but it is obvious

page_text: that the arrangement of bristles as herein before described may be used with like
advantage in most kind of brushes.
Dated this 22nd day of October 1897.
Improvements in or relating to Brushes, more especially to Tooth
Brushes.
I, ROBERT GLENDOUNING HUNTER, of 137, Avenue Road, Southampton, in the 1
County of Hants, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to brushes more especially to tooth brushes.
.In tooth and other brushes now ordinarily made all the hairs or bristles are set 1.
in the stock at right angles to same, thus when the brush is in use the bristles are
caused to more or less lie over in the opposite direction, in a line with the stock
or handle to that in which the brush is moved backwards and forwards.
The object of my said invention is to fit and arrange the bristles on the stock
of brush so that in use, in whatever direction the brush is moved lengthways, some 20
at least of the bristles shall work' at right angles, or approximately so, to the surface
upon which the brush is used.

In the accompanying drawings I have shewn what I consider to be the best way
of carrying out my invention in which:-
Fig. 1 is a side elevation of a tooth brush constructed according to my invention. 2
Fig. 2 a plan taken on the line a, a,
Fig. 3 a sectional side elevation taken on the lines b, b.
Fig. 4 a sectional side elevation taken on the lines c, c.
Fig. 5 a sectional side elevation taken on the line d.
Fig. 6 a plan of a tooth brush made according to another form or modification of 30
my invention.

Fig. 9 a sectional plan view taken on the lines f, f.
Fig. 10 a sectional plan view taken on the line 9.
Like letters indicate corresponding parts throughout the drawings.

In constructing brushes according to my invention I provide that some of the
rows of bristles will be fitted in the stock at right angles to the length of same, and
that other rows shall be fitted so as to lie in a more or less sloping direction; sloping
similarly but in opposite directions, but all the rows will meet at the face of brush 40
so as to form a close surface. Thus in whatever direction a tooth or other brush'
thus made is used, lengthways of the stock, some of the bristles will be working at
right angles, or approximately so, to the surface of the teeth, or other surface upon
which used thereby more effectually brushing same.
For the purpose of more effectively cleaning the back of the teeth I construct a 4
tooth brush, according to another form or modification of my invention, in manner
as shewn on the drawings by Figs. 6, 7, 8, 9 and 10, in which, instead of fitting the
bristles in the usual manner in the flat of the stock, I provide a clump A, on the
top or bottom side of same, and fit rows of bristles on the two sides of the said clump,

page_text: arranged similarly as hereinbefore described in as many rows as found convenient
and effective.
In using this form of brush on one side of the mouth one side of the brush will
be used, and the other side of brush for the opposite side of the mouth.
The bristles of this brush being situated either above or below the stock or handle
allow the bristles to more effectively reach and clean the lower part of the teeth at
the back of same.
I may however if preferred arrange for the bristles to be attached direct on each
side of one end of a stock or handle without forming a clump on same in manner
aforesaid.
I may also if preferred arrange that the two forms of tooth brushes as described
shall be fitted to one and the same stock or handle, one at each end of same.
I have described my improvements more particularly as applied to tooth brushes
but it is obvious that the arrangement of bristles as herein before described may be
used with like advantage in most kind of brushes, and further, that I can somewhat
modify the arrangement of the rows of bristles from that shewn on the accompany-
ing drawings, without departing from the nature of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1st. The improved brushes consisting of the parts all constructed arranged and
combined substantially as described with reference to the accompanying drawings
and operating as, and for the purpose above specified.
2nd. The construction of brushes with part sloping or angled bristles, as and for
the purpose specified.
3rd. The combination in a brush, adapted for cleaning teeth and for other
purposes, of vertical and sloping or angled rows of bristles, as, and for the purpose
specified.
