PROVISIONAL SPECIFICATION.
Improvements in Tooth Brushes.
I, ROBERT FITZMAURICE of Denny Street Tralee Ireland Physician and
Surgeon, do hereby declare the nature of this invention to be as follows :-
My invention consists in further improvements in tooth brushes according to
the principle of the invention for which I have applied for Letters Patent
No. 13552 of 1891. In accordance with the invention before specified I place the
handle of the tooth brush into an outer handle or drip reservoir. As the handles
of tooth brushes vary in thickness and size I have found it necessary to provide a
means for tightly fixing these varying sized handles into a uniformly sized outer
reservoir or handle.
This I accomplish by a flat bent spring enclosing the sides of the tooth brush
and when this together with the tooth brush is pushed into the handle or reservoir
it tightly fixes the said handle inside the reservoir as the flat spring is so shaped
in size as to bind against the interior of the reservoir and in being drawn together
tightly clasps the handle of the tooth brush in the same.
By this means I am able to overcome the difficulties which the varying sized
handles bring about in connection with my invention for which I have applied for
the aforesaid Letters Patent No. 13552 of 1891.
Dated this 23rd day of September 1891.

Improvements in Tooth Brushes.
ROBERT FITZMAURICE Medical Doctor, Denny Street, Tralee Ireland 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:-
My invention consists in further improvements in tooth brushes according to
the principle of the invention for which I have received Letters Patent No. 13,552
of 1891. In accordance with the invention before specified I place the handle of
the tooth brush into an outer handle or drip reservoir. As the handles of tooth
brushes vary in thickness and size I have found it necessary to provide a means
for tightly fixing these varying sized handles into a uniformly sized outer reservoir
or handle. This I accomplish by a flat bent spring enclosing the sides of the
tooth brush and when this together with the tooth brush is pushed into the handle
or reservoir it tightly fixes the said handle inside the reservoir as the flat spring
is so shaped in size as to bind against the interior of the reservoirs and in being
drawn together tightly clasps the handle of the tooth brush in the same.
By this means I am able to overcome the difficulties which the varying sized
handles bring about in connection with my invention for which I have received
the aforesaid Letters Patent No. 13,552 of 1891.
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
An improvement in tooth brush handles which consists of bent flat springs
which are fixed in the tube for which I have received Letters Patent,

page_text: numbered 13,552, and into which flat springs (the ordinary tooth brush handle is
tightly fitted, and which flat springs enable me to overcome a difficulty which
would otherwise occur, namely, of fitting into the tubes different sized ordinary
tooth brush handles.
