page_text: PROVISIONAL SPECIFICATION.
An Improved Tooth Brush with Wedge-shaped Bristles.
I, FRANZ ZELINSKI, of Kiew, in the Empire of Russia, Dental Surgeon, do hereby
declare the nature of this invention to be as follows:-
The tooth brushes heretofore used were not adapted to pass into the small spaces
between two teeth and to remove the tartar, remainders of food and the like
deposited therein, because these brushes had always a plane working surface, which
therefore could touch only the projecting points of the teeth of a set.
The subject of the present invention constitutes a brush which, besides the bristles
arranged in the ordinary manner, possess also a so-called "bristle wedge" of compressed
bristles, by the edge of which the deepest spaces between the several teeth can be
conveniently cleaned both from the outer side and from the inner side.
The brush consists of a handle of bone or of any other material suitable for this
purpose and the handle may be bent to any shape.
The softness, hardness and length of the hair may be varied.
Moreover I have provided in a new manner a wedge which consists of compressed
bristles more or less hard, and is cut at a sharp angle.
The wedge is either at the outer end of the brush or is fastened to the end of the
handle, at the point where I fix the bristle wedge.
Dated this 2nd day of September. 1896.

An Improved Tooth Brush with Wedge-shaped Bristles.
I, FRANZ ZELINSKI, of Kiew, in the Empire of Russia, Dental Surgeon, 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 :-
The tooth brushes heretofore used were not adapted to pass into the small spaces
between two teeth and to remove the tartar, remainders of food and the like deposited
therein, because these brushes had always a plane working surface, which therefore
could touch only the projecting points of a set of teeth.
The subject of the present invention constitutes a brush, which have the bristles
arranged in the ordinary manner; possess also a so-called "bristle wedge" of
compressed bristles, by the edge of which the deepest spaces between the several
teeth can be conveniently cleaned both from the outer side, and the inner side.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and figures
marked thereon.
Figs. 1, and 2, represent two constructional forms of the new brush, one in plans,
and other side elevations.
Figs. 3, and 4, illustrate the mode of using the brush against the teeth.

page_text: The brush consists of a handle 1 of bone or of any other material suitable for this
purpose and the handle may be bent to any shape one or the other side at a.
The ordinary hair or bristle brush 2, for its softness, hardness and length of the
hair, may be varied to any extent.
Moreover, I have provided in a new manner a wedge 3 which consists of compressed
bristles more or less hard, and is cut at a sharp angle.
The wedge is either at the outer end 6 of the brush or is fastened to the end of
the handle b', at the point where I fix the bristle wedge 3.
The bristle wedge 3 situated at the free end of the handle of the brush is from two
to three times broader than the first named, and its edge is at a right angle to the
edge of the latter.
Haying 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. In a tooth brush, the arrangement of a wedge 3 consisting of compressed
bristles either at the end of the brush, or at the end of the brush handle, or at both
points, for the purpose of passing with the edge of this bristle part into the small
spaces between the teeth and enabling these spaces also to be cleaned, substantially
as described and according to the accompanying drawing.
2. In a tooth brush, the combination of the various parts as described in the above
specification for the purpose specified.
Dated this 1st day of June 1897
