IMPROVEMENTS IN TOOTH BRUSHES
Year: 1880

page_text: LETTERS PATENT to Louis Holz and Leopold Meyer, Manufacturers, of the
City of Paris, in the Republic of France, for an Invention of "IMPROVEMENTS
IN TOOTH BRUSHES."
PROVISIONAL SPECIFICATION left by the said Louis Holz and Leopold
Meyer at the Office of the Commissioners of Patents on the 4th February
1880.
LOUIS HOLZ and LEOPOLD MEYER, Manufacturers, of the City of Paris, in the
Republic of France. " IMPROVEMENTS IN TOOTH BRUSHES."
The improved tooth brush is constructed in the following manner :-
The brush head is circular, of ivory, bone, or other substance; it has an internal
groove or grooves in which the bristles are mounted.
The brush is articulated to a metal shaft, which latter is set in a handle of ivory
or other matter ornamented as desired.
The object of the circular form of the brush in conjunction with its articulation
to the handle, and the method of fixing the bristles in grooves, is intended to
facilitate the movement of the brush inside the mouth and clean the teeth on each
Bide and in the centre simultaneously.

-The brush
The improved tooth brush is constructed in the following manner :-
head is circular, of ivory, bone, or other substance; it has an internal groove or
grooves in which the bristles are mounted.
The brush is articulated to a metal shaft, which latter is set in a handle of ivory
or other matter ornamented as desired. The object of the circular form of the
brush, in conjunction with its articulation to the handle, and the method of fixing
the bristles in grooves, is intended to facilitate the movement of the brush inside
the mouth and clean the teeth on each side and in the centre and lower parts
simultaneously.
Two principal parts therefore distinguish this brush, first, the brush proper,
comprising the hair or bristle mounting, and secondly, the movable handle.
The accompanying Drawings will clearly illustrate the nature and objects of the
Invention aided by the following description thereof:-
Figs. 1 and 2 represent a front and side view of our improved brush, and Figs. 3
and 4 a slight modification of the same principle seen as front and side views; in
these two latter Figures the brush head is straight, so that there is no necessity for
the groove being circular.
The new system of construction or articulation of the brush head consists of the
brush mount A and handle D. The brush which forms the principal part of this
small apparatus is or may be of ivory, bone, or any other suitable substance that
can be applied with equal effect.
This brush head is particularly constructed, as will be observed Fig. 1; it is
circular so as to act freely inside the mouth without difficulty; it has an internal
groove whence the hairs or bristles B, as the case may be, project for cleaning the
teeth.
These bristles, hairs, and so forth, are arranged on each of the sides internally as
well as at the bottom, so that the teeth may be simultaneously cleaned on each side
of the mouth as well as at the bottom of the jaw.
This brush head works or rather circulates inside the mouth by means of the
'handle D, which is supplied with a metal shaft C, whose end traverses the centre
of the mount A and is there securely fixed by a small rivet, as will be seen in the
Drawing.
The peculiarity of the mounting being the circular groove wherein the bristles,
hairs, or what not are fixed.
The handle may be of any desired form and more or less ornamented as required,
and of any suitable substance, and the brush head or mount turns with facility at
the end of the shaft.
In witness whereof, we, the said Louis Holz and Léopold Meyer, have hereunto
set our hands and seals, this Nineteenth day of July, in the year of our
Lord One thousand eight hundred and eighty.
