PROVISIONAL SPECIFICATION.
An Improved Tooth-brush.
I, ERNEST EDWARD BOYCE BOEHMER of 3 Westmoreland Road, London, W.,
in the County of Middlesex, Clerk in H.M. Civil Service do hereby declare the
nature of this invention to be as follows:-
The ordinary form of tooth-brush has a straight flat surface which when used
rubs against the prominencies of the teeth but to a large extent leaves the recesses
between them untouched, whereas my improved tooth brush cleans all the ordinary
recesses between the teeth as well as the other more accessible parts.
The brush is constructed in a manner similar to that of the ordinary brushes
with this exception, instead of the rows of clusters of hairs or bristles being
evenly spaced, as is at present the case, a whole row of the clusters of hairs or
bristles in the width of a brush is left out at intervals, by which arrangement the
hairs or bristles have more room for play and the brush as a whole acts as if a
number of small brushes were brought into use at one and the same time, and the
result is that a most efficient tooth cleaner is produced; and further by leaving
out the clusters of hairs or bristles at intervals as just described the hairs or
bristles are more readily aerated and quickly dried than can the hairs or bristles
of the ordinary brush be.

I, ERNEST EDWARD BOYCE BOEHMER of 3 Westmoreland Road, London in
the County of Middlesex, Clerk in H.M. Civil Service 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 improved tooth-brush is constructed in the ordinary way with this exception,
that every fourth or fifth or a combination of the two transverse row of tufts of
bristles or hairs is omitted, as shown by the drawing, in plan by Figure 1, and in
elevation by Figure 2, by doing which gaps will be left at intervals, and every
cluster of tufts will consist of three or four transverse rows, unless, for the sake of
economy, the last cluster is made of a less number.
By this arrangement of the tufts of hairs or bristles a better tooth cleaning
brush results than has hitherto been obtainable. The improved tooth-brush has
the following advantages; it is sufficiently aerated, it has plenty of scrubbing
surface, it can efficiently clean the majority of the irregularities to be found in the
surfaces of teeth, which the common brush cannot do efficiently without an
excessive amount of trouble on the part of its user, and, unlike the brushes that

page_text: have the ends of their tufts of bristles or hair cut to a point so as to give a
corrugated, zigzag, or saw-tooth like appearance when viewed from the sides or
ends of the brushes, the extremities of brushes made in this manner are not liable
to wear down, while the pointed tuft type are, and then these latter are no better
than the ordinary brush.
Further by the adoption of clusters of three or four transverse rows of bristles
or hairs these latter are well supported by their neighbours and are not so linble
to break off at the root as are transverse rows of bristles or hairs spaced widely
apart.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
Tooth-brushes made with every fourth or fifth transverse row of tufts of bristles
or hairs, reckoning from the end further from the handle, omitted or a combination
of this arrangement as herein set forth and shown in the drawing.
