Improvements in Tooth Brushes.
I, CARL EDUARD FLEMMING, of Schönheide, Germany, Brush Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of tooth brushes in which the
brush body or bodies is or are made to project laterally at an angle from the end
of the stem or handle.
The brush body may be made to project either at a right angle from one or
both ends of the stem, or at an acute or an obtuse angle therefrom, or when
there is a brush body at each end of the stem, the one may project at an acute
angle and the other at an obtuse angle, both brush surfaces being made to project
either from opposite sides or from one and the same side of the stem. The brush
body or bodies may, in either of the above arrangements, be of any desired
configuration; thus they may be either oblong or square or polygonal or round,
and either flat or convex or concave or stepped.
Such tooth brushes serve for cleaning both the inner and the outer surfaces of
the teeth in vertical direction, in particular, this arrangement of laterally projecting
brush body enables the innermost teeth to be effectually cleaned.
When two brush bodies are provided on one stem, both brushes may either
project in one and the same direction, or in opposite directions, and either both at
the same angle or at different angles, whether right angles, or acute or obtuse
angles.
Also, both brush bodies can be made flat or both convex or concave, or the one
may be convex and the other concave so as to serve respectively for cleaning the
outer surfaces and the inner surfaces of the teeth.
The brush back may also be flat while the brush surface is concave or convex,
or with one part at a higher or lower level than the other part.
Instead of projecting entirely to one side of the stem the brush body may also
project to a certain extent to the other side, or it may project equally to either
side thus forming a T head to the stem.
When two brush bodies are provided on one stem, the one may project laterally
in either of the above described ways, and the other may be arranged in line with
the stem like an ordinary tooth-brush, the brush surface being either flat, concave
or convex.
The brush body or bodies can be made either in one piece with the stem or of
separate pieces joined thereto, and they may be of any suitable material such as
bone, wood, vulcanite, caoutchouc, celluloid &c., and the brush surface may either
be of bristles or of hair, caoutchouc or sponge &c.

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 :-
My invention relates to the construction of tooth brushes having the brush body
or bodies projecting laterally from the end or ends of the stem or handle as I shall
describe referring to the accompanying drawings.
Figure 1 shews the brush body, projecting from one end of the handle, and
Figures 2 and 3 shew brush bodies projecting from both ends of the handle, at
right angles thereto.
In Figures 4 and 5 the brush bodies make acute angles with the handles and in
Figures 6 and 7 they make obtuse angles;
Figures 8 and 9 shew two brush bodies both on one side of the handle, the one
in each case at an acute and the other at an obtuse angle to it,
Figures 10. 11. 12 and 13 shew the brush bodies of square, nearly square or
round form. Fig. 14 shews a modification.
Such tooth brushes serve for cleaning both the inner and the outer surfaces of
the teeth in vertical direction; in particular, this arrangement of laterally projecting
brush body enables the innermost teeth to be effectually cleaned.
When two brush bodies are provided on one stem, then both brushes may either
project in one and the same direction or in opposite directions and either both at
the same angle or at different angles, whether right angles or acute or obtuse
angles. Also both brush bodies can be made flat or both convex or concave, or
the one may be convex and the other concave, so as to serve respectively for
cleaning the outer surfaces and the inner surfaces of the teeth.
As shewn in Figure 1, the brush is curved so as to suit it for cleaning the
outside of the teeth vertically and is at the left side of the handle. The bristles
may be on the concave, instead of the convex side of the body, suiting it for
cleaning the inside of the teeth. The brush may be on the right side of the
handle and may then be either convex or concave. In like mauner the brushes
projecting on the same or on opposite sides of the handles in Figures 2 and 3, may
be convex or concave, or the one may be convex and the other concave.
brush Figure 4 projecting at an acute angle is convex, as are the two brushes
oppositely projecting at an acute angle in Figure 5. The brush Figure 6 is suited
for cleaning the outside of the back teeth, and the double brushes shewn in
Figures 7. 8 and 9, making different angles with the stems, may be either convex
or concave.
The
For cleaning special parts of the jaw or mouth brushes of small extent square,
rectangular or round may be arranged as shewn in Figures 10 and 11 at the side
of the handle at one end thereof, or as shewn in Figures 12 and 13 at both ends,
and these brushes may be concave or convex. In some cases as shewn in Figure 11,
bristles may project from the end of the handles.
The double brush shewn in Figure 14, has its two sets of bristles arranged at
right angles to one another, the one which is not in line with the handle extending
mostly to the right, with a small projection to the left, but this projection may be
made equal to the other as indicated by the dotted lines.
The bristles in all these forms of brushes may have flat, convex or concave
surfaces or they may be stepped as shewn in Figure 6; also these surfaces may be
of projecting or hollow spherical or conical form, and the bristles may be of any
desired strength, in the case of the double brushes the bristles of the one may be
stiff and those of the other weak.

page_text: The brush body or bodies can be made either in one piece with the stem or of
separate pieces joined thereto, and they may be of any suitable material such as-
bone, wood, vulcanite caoutchouc, celluloid &c. &c., and the brush surface may
either be of bristles or of hair, caoutchouc or sponge &c.
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 one or two brush bodies which have flat, convex,.
concave or stepped bristle surfaces, and laterally project each one way at an angle
to the handle from its ends substantially as described with reference to Figures 1.
to 13 inclusive.
2. A modified tooth brush having the brush bodies at opposite ends of the
handle arranged at right angles to one another, substantially as described with.
reference to Figure 14.
