Tooth Brush.
1, RUDOLF MISCHE of Blomberg, in the Empire of Germany, Manufacturer, do
hereby declare the nature of the said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
This invention consists in a new combination of parts constituting a brushing device
applicable more especially as a tooth brush.
The device consists of a sleeve in which is journalled a spindle carrying at one end
a brush of circular, cylindrical, conical or other convenient form, the latter lying in
an extension attached to said sleeve. The said extension may be cylindrical or of
other shape so as to form a guard plate over one half side (more or less) of the brush,
the latter being capable of revolving within the guard plate.
The spindle carries a crank by which it may be revolved.
Referring to the accompanying drawings:
Fig. 1 is a side view of the brushing device.
Fig. 2 is a sectional view of the sleeve and guard.
Fig. 3 is a sectional view of the crank attached to the spindle.
Fig. 4 is a view of the spindle and brush thereon.
HHH' is a casing made of caoutchouc or any other uninjurious material, B the
brush with spindle C and G the crank. The part H2 of the casing serves to receive
the brush B the spindle C of which is journalled in H and fastened by the rear
diminished end d by a set screws in slot b¹ of the crank G. To prevent the brush
spindle from sliding in the casing, a disc b is arranged on the brush spindle, said disc
being in contact with the front part of the sleeve й, while the crank G abuts against
the rear part of the sleeve H.
On the front end of the brush is provided a small knob k for the purpose of
protecting the soft parts of the mouth when introducing the brush.
The brush when worn out, can be easily replaced by a new one by simply loosening
the screw 8.

page_text: Tooth brushes heretofore used, have the drawback, that particles of food instead of
being removed, are partly rubbed into the interstices between the teeth and cause
injury thereto.
To moisten the brush for use, it is placed into the liquid destined for cleaning the
teeth, the brush receiving as much as is required for cleaning one row of teeth.
The casing of the brush is then held with the left or right hand according as
whether the left or right side of the teeth is to be cleaned, and introduced horizontally
into the mouth, the shield H2 of the casing being directed away from the teeth, and
the edge a or a¹ respectively of the casing laid softly on to the upper or lower gum
respectively and the brush turned with the free hand.
The turning of the brush must be effected with the upper row of teeth downwardly
and with the lower row of teeth upwardly the casing being moved slowly to and fro.
The under sides of the teeth can be treated in the same manner.
After using the improved tooth brush, it may be pressed on to the inner side of a
vessel filled with water, the brush revolved a few times by means of the crank, a
perfect cleaning of the brush being thereby effected.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is :-
:-
A brushing device consisting of a brush B revolvably journalled in the casing H H¹ H³,
said brush being rotated by the crank G, substantially as set forth.
