An Improvement in Tooth, Nail, and other Brushes.
I, WILLIAM ADDIS, of 44, Herbert Street, Hoxton, London, N. Tooth and
Nail Brush Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improvement in tooth, nail, flesh, scrubbing, and other
brushes in the use of which water is employed for cleaning purposes and it has for
its object to provide a means of enabling the water usually retained at the roots of
the tufts of bristles to be drained off when the brush is put away after use and so
avoid the decay to which the tufts are liable through the action of the moisture
and whereby more especially in the case of tooth brushes the brush is also rendered
sweeter and preserved in a more sanitary condition by preventing the secretion of
impure watery deposits at the roots of the tufts.
To this end my invention consists in providing the brush "stock" or "block"
with rows of drainage holes drilled therethrough transversely from side to side,
said holes coinciding with the rows of holes in which the tufts are set and
communicating therewith, the drainage holes being left permanently open to allow
water retained by the bristles to drain off and evaporate.

An Improvement in Tooth, Nail, and other Brushes.
I, WILLIAM ADDIS of 44, Herbert Street, Hoxton, London, N. Tooth and
Nail Brush Manufacturer, 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 relates to an improvement in tooth brushes, nail brushes, flesh
brushes, scrubbing brushes, and others with which water is employed, and the
improvement has for its object to avoid the sourness and ultimate decay due to
fermentative action about the roots of the bristles consequent on the retention of
moisture when the brush is put away after use and more especially in the case of a
tooth brush to preserve the brush in a sweeter and more sanitary condition.
The invention is illustrated, in the accompanying drawing forming part of this
specification wherein I have illustrated in
Figure 1 a part sectional side view of a tooth brush and in
Figure 2 a section through the brush stock, the bristle tufts being omitted and
both figures being drawn to an enlarged scale.
The invention consists in providing the brush stock a with transverse drainage
channels 6 parallel to the face of the stock and passing through the stock from
edge to edge, one such channel for each row of holes e in which the tufts of
bristles are set in the ordinary way. Each drainage channel b communicates with

page_text: the corresponding row of holes c, but instead of directly intersecting therewith it
passes by preference towards one side of the row, as shewn, in order that the roots
of the tufts of bristles shall not stand completely across and obstruct the channels b
but be merely exposed at one side, leaving a clear thoroughfare for drainage.
These channels b being left permanently open at the sides of the brush stock any
water retained by the roots of the tufts may drain off and evaporate.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Providing a brush stock with drainage channels traversing the stock from edge
to edge parallel to the rows of holes in which the bristles are set and communicating
therewith so that the roots of the tufts are exposed at such drainage channels
substantially as and for the purpose specified.
