EUGENIE VICTORIA GOAD of No. 3 Westrop Villas Canonbury, London, N. and
EDWARD GOAD of No. 28 Northampton Street, Essex Road, London, N. manufacturer,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to produce a tooth brush, that will enable the person
using it to force water or any other kind of liquid into the mouth at the same time the
teeth are being cleaned with the brush, and to carry out this object, a small hole is
made through the handle of the brush into a small space above the bristles or between
the whole of the back of the brush and the bristles, and perforate the under part of
the brush and between each bunch of the bristles with small holes. Or by means of a
groove along the under side of the handle to the head of the brush and a small tube
At the end of the handle
of metal or glass perforated with small holes at the end.
which is made shorter than those at present in use, a thread is cut to screw the reservoir
upon.
A reservoir or hollow ball of different shapes and sizes to bold the liquid, and made
of india rubber or any other suitable material, is fastened or screwed upon the thread
cut upon the end of the handle.
The reservoir or ball can be filled with liquid by unscrewing from the handle, or a
hole in some other part, with a screw cap and cup may or may not be used.
Having now described the nature of our invention, we would observe that we do not
limit ourselves to the precise details herein given as various modifications may be
made therein while retaining the essential features of our said invention.
Dated this 23rd day of July 1887.

page_text: We, EUGENIE VICTORIA GOAD and EDWARD GOAD, of No. 73, Ludgate Hill, in
the City of London, Manufacturers, 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 object of this invention is to produce a tooth brush which will enable the person
using it to force water or other liquid into the mouth at the same time that the teeth
are being cleaned with the brush. For this purpose we make a small hole through
the handle of the brush into a small space above the bristles and perforate the under-
part of the brush and between the bristles with small holes. Or we form a groove
along the under-side of the handle to the head of the brush having a small tube of
metal or glass perforated with small holes at the end. To the end of the handle of
the brush which is advantageously made shorter than those at present in use we apply
an elastic bag or hollow ball of suitable size serving as a reservoir to hold the liquid;
the said reservoir is screwed or otherwise fastened upon the end of the handle of the
brush.
In order to enable our invention to be fully understood we will proceed to describe
how the same can be carried into practice by reference to the accompanying drawing
in which figure 1 is a side elevation and figure 2 a longitudinal section of a tooth
brush provided with our improvements; figure 3 is a horizontal section on the
line A B of figure 1. Similar letters in all the figures represent similar parts.
a is the handle of the brush; bis the hole we make through the handle a, and which
hole extends nearly to the top of the back or body c of the brush; d, d, d are the holes or
perforations which we make in the under-part of the back or body of the brush, the
said holes d opening into the space or continuation of the hole b in the back of the
brush e is the elastic bag which we fit to the end of the handle of the brush; in the
drawing the end of the brush is shown slightly tapered so that it will fit. into the
corresponding hole in the mouth of the bag which arrangement we have found con-
venient in practice as it allows of the bag being easily detached from and placed on
the end of the brush, but the end of the brush may be screw-threaded so as to screw
into a threaded hole in the mouth of the bag.
By this arrangement it will be obvious that if the bag e be filled with water or other
liquid and the brush be placed in the mouth of a person using the brush the liquid
can by squeezing or collapsing the bag e be forced through the hole in the handle
and through the holes d, d, d in the back of the brush into the mouth for cleaning the
teeth or otherwise.
The bag or reservoir can be filled with liquid through its mouth by detaching it
from the brush or it can be filled by collapsing the bag and drawing the liquid through
the holes d, d, and as will be well understood.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination with a tooth brush of an elastic reservoir in communication
with the back or body of the brush between the bristles whereby liquid from the
reservoir can be forced into the mouth while the teeth are being cleaned.
2. The manufacture and use of the improved tooth brush hereinbefore described
and illustrated in the accompanying drawing.
