PROVISIONAL SPECIFICATION.
Improvements in Tooth Brushes,
I, Dr. Med. HEINRICH LÖHERS, of Hauptstrasse 121, Heidelberg, in the
Empire of Germany, Chemist, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object to remedy the inconvenience hitherto
experienced in the use of tooth brushes, that is to say, to enable a ready removal
of the food lodged between the teeth by facilitating the moving of the brush in the
direction of the growth of the teeth.
The essential features of this invention consist in forming the tooth brush with
a cranked handle, so as to facilitate the moving of the brush in a vertical direction
instead of in a horizontal one and in forming the brush head and handle separate,
so as to render the brush head exchangeable for cleansing or renewing purposes.
According to one form of my invention I use a handle of suitable material bent
to a certain angle or simply curved, which handle serves to receive a small brush
in a hole formed with slotted sides which form springs just above the solid part of
the handle. The said brush is furnished with a stem having a small shoulder,
which stem is a little larger than the said hole or socket which receives it. The
extremity of this stem is cut vertically so as to form a pair of tongues and fit into
the hole or socket of the handle in which the brush is secured by means of a ring
placed on the said handle. This ring internally is formed diametrically with a
midfeather which serves to prevent the lateral displacement, whilst the aforesaid
slot prevent the brush leaving after the ring is drawn tight downwards.
It evident that this combination constitutes only one of the various methods
possible in which my invention may be carried out in practice.

COMPLETE SPECIFICATION.
Improvements in Tooth Brushes.
I, Dr. Med. HEINRICH LÖHERS, of Hauptstrasse 121, Heidelberg, in the
Empire of Germany, Chemist, 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 :-
Through the organs of mastication a series phenomena of pathologic order take
place, the etiologic causes of which are due to insufficient care given to the said
organs.
To take proper care of teeth and gums, it is necessary that the teeth are brushed
on the whole surface and the brush be moved in the direction of the growth of
teeth and by pressing the gums in rubbing against the teeth and to remove with
certainty the food lodged between the same.
The tooth brushes heretofore in use are insufficient in this respect and clean the
'teeth badly, being moved exclusively along the jaws.
For hygienic reasons it is also necessary to be able to maintain the brush aseptic,.
which is not the case with the brushes heretofore in use.
This invention has therefore for its object to remedy these defects and also to
reduce the cost of new brushes by rendering the handle always usable.
And in order that my invention may be more fully understood I have caused to.

page_text: be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a front view of the handle.
Fig. 2 a section and Fig. 3 a side view.
Figs. 4 & 5 are respectively a front view and an end view of the brush.
Figs. 6, 7 & 8 are views of the tightening ring.
Fig. 9 is a section showing the connection between the brush and the handle.
Fig. 10 is a horizontal section of the handle.
Figs. 11-15 show the brush fixed to the handle in different positions.
In carrying out my invention I use a handle of vulcanized rubber, steel, wood, or
any other suitable material bent to a certain angle or simply curved, see Figs. 1
& 3, which handle serves to receive a small brush, see Fig. 4, in a hole a Figs. 2
& 3, formed with slotted sides which form springs just above the solid part of the
handle, Figs. 1 & 2. e are the slots in the side of the neck of the handle, Figs. 2
& 9. The brush itself is made of such size as to allow of being put, when not in
use, into a bottle with large neck, containing 30 grammes of an anti-septic solution.
The said brush may be rectangular, circular or of any other suitable form and is
furnished with a slightly conical stem d having a small shoulder, which stem d is a
little larger than the hole or socket a which receives it. The extremity of this
stem has a vertical slit which forms a pair of tongues and fit into the hole or
socket a of the handle in which the brush is secured by means of a ring, Figs. 6, 7
& 8, placed on the handle. This ring internally is formed diametrically with a
midfeather g, Figs. 7 & 8, which serves to prevent the lateral displacement, whilst
the slit prevents the brush leaving after the ring is drawn tight downwards,
Figs. 9 & 10.
It is evident that this connection constitutes only one of the various methods
possible which may be employed for this purpose.
Fig. 11 represents the brush as adapted for cleaning the inner surface of the
upper and lower front teeth, Fig. 12 for cleaning the outer surface of the same,
Fig. 13 for cleaning the right side of the upper and left side of the lower and
Fig. 14 the left side of the upper and right side of the lower back teeth. Fig. 15 is
a perspective view of the whole of the brush.
I may remark that I reserve the right of applying the whole or part of my inven-
tion for other similar purposes for which it may be suitable, to combine for instance,
any kind of instruments for application to handles as described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
A tooth brush made of any suitable material and composed of an angular or
curved handle of vulcanized rubber, stcel, wood or other suitable material, formed
with a hole adapted to receive a small removable brush with a stem or other
instrument for polishing the teeth and the rotation of which brush in the said handle
permits of fixing it in various determined angular positions by means of a suitable
tightening arrangement which permits of giving the masticatory organs proper care,
substantially as and for the purpose set forth.
