AN IMPROVED TOOTH BRUSH
Year: 1884

page_text: I JOHN CYRIL STANLEY HARPER of N° 6 Picton Place Newcastle on Tyne in
the County of the same City Dentist do hereby declare the nature of my invention
for "AN IMPROVED TOOTH BRUSH" to be as follows:-
The object of this invention is to construct a tooth brush in such a manner that
every portion of the teeth to be cleaned may be reached in a much more complete
and convenient manner than by the use of tooth brushes as hitherto constructed
It consists in providing a concave brush at right angles to the handle by which
it is held for the purpose of conveniently moving the brush up and down to clean
out the spaces between the teeth and a similar brush in a line with the handle
for drawing from left to right in the usual manner for cleaning the outer surface
of the teeth. To conveniently obtain both the up and down and left to right
motions with one brush I connect a concave brush with a handle by means of a
screw forming a centre upon which the handle may turn so that the handle may
be held at any angle while the concave brush remains within the lips in contact
with the teeth and owing to this swivelling action the brush may be drawn and
pushed from left to right or up and down without removing the brush from the
mouth. When so constructed I fit the same handle with a convex brush at the
other end to be used as a palate brush for cleaning the interior surfaces of the teeth.
In the accompanying drawings Fig 1 is a side view and Fig 2 is plan of the
brush handle fitted at one end with the convex palate brush Fig 3 is the screw
by which a concave brush may be fitted at the other end of the brush handle.
Fig 4 is a side view and Fig 5 is a plan of the concave brush Fig 6 is a side view
of the handle fitted with a brush at each end as described.

County of the same City Dentist do hereby declare the nature of my invention
for "AN IMPROVED TOOTH BRUSH" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The object of this invention is to construct a tooth brush in such a manner that
every portion of the teeth to be cleaned may be reached in a much more complete
and convenient manner than by the use of tooth brushes as hitherto constructed.
It consists in providing a concave brush at right angles to the handle by which
it is held for the purpose of conveniently moving the brush up and down to clean
out the spaces between the teeth and a similar brush in a line with the handle
for drawing from left to right in the usual manner for cleaning the outer surface
of the teeth. To conveniently obtain both the up and down and left to right
motions with one brush I connect a concave brush with a handle by means of a
screw forming a centre upon which the handle may turn so that the handle may
be held at any angle while the concave brush remains within the lips in contact
with the teeth and owing to this swivelling action the brush may be drawn and
pushed from left to right or up and down without removing the brush from the
mouth. When so constructed I fit the same handle with a convex brush at the
other end to be used as a palate brush for cleaning the interior surfaces of the teeth.
In the drawings accompanying my provisional specification Fig. 1 is a side view
and Fig. 2 is a plan of the brush handle fitted at one end with the convex palate
brush Fig 3 is the screw by which a concave brush may be fitted at the other
end of the brush handle. Fig. 4 is a side view and Fig 5 is a plan of the concave
brush. Fig 6 is a side view of the handle fitted with a brush at each end as
described. When the handle of the brush is made of a plastic material such as
vulcanite then I attach the swivelling brush C to the handle A by means of a piece
of metal tube B as shown in the accompanying drawings. One end of the tube B
is opened out before embedding the same into the vulcanite previous to the vul-
canising process and the other end is opened out after placing the swivelling
brush in position. The handle A is formed with a raised circular portion which'
rests in a circular recess made in the swivelling brush C so as to relieve the tube B
from strain when the brush is in use.
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
1° A tooth brush having that portion which carries the bristles attached to
the handle (by which the tooth brush is to be held) by means of a screw or an
embedded tubular rivet forming an axis upon which the brush may revolve for

page_text: the purpose of holding the handle at any required angle to perform alternately the
up and down and left to right motions as required.
2° A tooth brush having that portion which carries the bristles placed at right
angles to the longitudinal axis of the handle by which the tooth brush is to
be held.
3° The combination of the convex or palate brush and concave or swivelling
brush placed one at each end of a handle common to both.
All as and for the purposes described,

page_text: COMPLETE SPECIFICATION,
I JOHN CYRIL STANLEY HARPER of 6 Picton Place Newcastle on Tyne in the
County of the same City Dentist do hereby declare the nature of my invention
for "AN IMPROVED TOOTH BRUSH" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to construct a tooth. brush in such a manner that
every portion of the teeth to be cleaned may be reached in a much more complete
and convenient manner than by the use of tooth brushes as hitherto constructed.
It consists in providing a concave brush at right angles to the handle by which
it is held for the purpose of conveniently moving the brush up and down to clean
out the spaces between the teeth and a similar brush in a line with the handle
for drawing from left to right in the usual manner for cleaning the outer surface
of the teeth. To conveniently obtain both the up and down and left to right
motions with one brush I connect a concave brush with a handle by means of a
screw forming a centre upon which the handle may turn so that the handle may
be held at any angle while the concave brush remains within the lips in contact
with the teeth and owing to this swivelling action the brush may be drawn and
pushed from left to right or up and down without removing the brush from the
mouth. When so constructed I fit the same handle with a convex brush at the
other end to be used as a palate brush for cleaning the interior surfaces of the teeth.
In the drawings accompanying my provisional specification Fig. 1 is a side view
and Fig. 2 is a plan of the brush handle fitted at one end with the convex palate
brush Fig 3 is the screw by which a concave brush may be fitted at the other
end of the brush handle. Fig. 4 is a side view and Fig 5 is a plan of the concave
brush. Fig 6 is a side view of the handle fitted with a brush at each end as
described. When the handle of the brush is made of a plastic material such as
vulcanite then I attach the swivelling brush C to the handle A by means of a piece
of metal tube B as shewn in the accompanying drawings. One end of the tube B
is opened out before embedding the same into the vulcanite previous to the vul-
canising process and the other end is opened out after placing the swivelling
brush C in position. The handle A is formed with a raised circular portion which
rests in a circular recess made in the swivelling brush C so as to relieve the tube B
from strain when the brush is in use.
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

the handle (by which the tooth brush is to be held) by means of a screw or an
