PROVISIONAL SPECIFICATION.
Improved Tooth Brushes for Effectually Cleansing the Teeth.
JOHN SUGDEN CRAPPER Doctor of Dental Surgery, of the White House Hanley
in the County of Stafford do hereby declare the nature of this invention to be as
follows:-
The form of the bristles and the shape of the frames are favorable to the thorough
cleansing of the teeth; the brushes being used upwards & downwards will pass into
the interstices thus cleansing the sides as well as the labial and lingual surfaces of the
teeth. The upper central incisors being larger than the laterals, and in the lower
teeth the reverse being the case, the bristles are placed proportionately to suit thein
also. The brush for the labial surfaces of the teeth is shaped concavely, & that for
the lingual surfaces convexly, thus when being used the brush will be in contact its
whole length with Teeth. They are the smallest brushes for the purpose ever
introduced, & will be more convenient & effectual in their work. It is intended to
produce single handed brushes in both cases. It is also intended to make the brushes
in three sizes viz. :-adults, medium & childs.
Dated this Ninth day of June 1886.

page_text: 1 JOHN SUGDEN CRAPPER Doctor of Dental Surgery, of the White House Hanley
in the County of Stafford, 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 :-
This Invention relates to certain improved tooth brushes for cleansing the teeth and
as will be seen from the accompanying drawings the form of the bristles and the shape
of the frames are favourable to the through cleansing of the teeth; the brushes are
small and being used upward upwards and and downwards will pas into the interstices
between the teeth thus cleansing the sides as well as the labial and lingual surface of
the teeth. The upper central incisors being larger than the laterals and in the lower
teeth the reverse being the case the bristles are placed proportionately to suit them
also the brush for the labial surfaces of the teeth is shaped concavely and that for the,
lingual surfaces convexly thus when being used the tufting of the brush will be in
contact along its whole length with the Teeth.
The brushes are made small, particularly the one for the labial surfaces, which allows
of the bristles being pressed between the intersticies of the teeth; they are fitted to a
handle or hand piece having a cavity or hollow therein for holding small articles
required such as floss silk and holder, the size and shape of the brushes are convenient
for introduction into the mouth and are very effective in their work.
In the drawings annexed hereto Fig. 1. represents a construction of the double
brush with the handle divided at a, and provided with an internal hollow for holding
such matter as floss silk and holder for same or as required. Fig. 2. represents the
same brush with the handle parts separated. Fig. 3 represents the bruslies made on
short pieces b, c, of ivory, vulcanite, or of required material for backs and these are
fitted at a, to a cylindrical piece d, for the handle. The bodies e, of the brushes for
the lingual surfaces (inside of dental arch) are of convex shape and the bodies of the
brushes for the labial surfaces (outside of dental arch) are concave. In the case of
the bodies e the shank e¹ is bent as shown, but in the case of the bodies f the shank
may be nearly straight.
The dotted arrow lines of Fig. 1. indicate that single brushes may be made but in
that case a pair would be required. It is intended to make the brushes in three
sizes viz. : adults" "medium" and "child's."
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 :
The improved tooth brushes constructed, combined and arranged as and for the
purposes herein set forth and shown by the drawings.
