Improvements in the Construction of Hollow Backed Brushes for
Supply of Liquid.
1 REGINALD HADDAN of the Firm of Herbert Haddan & Co. of 18 Buckingham
Street, Strand, W.C. London, Patent Agent, do hereby declare the nature of this
invention, a communication to me from abroad, by Paul Hochet of 24 Rue des
Fossés St. Jacques Paris in the Republic of France, Brush Manufacturer, to be as
follows:-
―:
This invention relates to a new construction of hollow backed brushes, which is
applicable to brushes of all kinds, and in which the frame or back of metal or
any other material, is hollow and adapted to receive in its interior or hollow space
antiseptic or other liquids which, passing through the bristle setting holes, will
soak the same as desired. The exterior plate or shell from which the bristles
project, is provided with holes of different form and shape, according as the style
of brush requires. Within the hollow back or body is another shell or plate
perforated in the same manner, and the two shells are soldered to each other, or
folded or riveted together, or united by any other means, so as to leave between
them a certain free space.
To set the bristles, each bunch of bristles is passed through a hole of the outer
shell, and is fastened on to the inner shell by the ordinarily employed methods of
setting bristles, the hairs being passed through the corresponding hole of the inner
shell. On the back or upper surface of the brush body is attached a slightly
curved plate. Antiseptic or other liquids can be put into the interior of the frame
by means of a hole which is closed by a threaded plug. This hole may be
arranged on the back of the brush or on any other part that may be judged
convenient. The liquid can be introduced directly or with the aid of a caoutchouc
flask or ball. The opening is then closed by means of the plug, and, as the air is
debarred from passing into the hollow back, the liquid cannot escape through the
But when the
holes of the frame, which are partially closed by the bristles.
brush is used, there is a certain amount of draught in the bristles of the setting
in consequence of their flexion and, following the capillary attraction, the liquid
will soak the bristles from the roots up to their extremity, and so communicate
itself to the human hair or other object to which the brush is applied. This
delivery of the liquid can be regulated in different ways: by loosening the threaded
plug and so giving more or less air-said plug being hollow and having holes at
different heights, or by removing this plug entirely and adapting in its place a
flask or ball of india rubber or caoutchouc, the compression of which causes the
liquid driven by the compressed air, to escape. The interior of the back may be
fitted with a sponge or other absorbing material, soaked with the antiseptic or
other liquid, and this liquid can be caused to run out by a pressure exerted in any
convenient way upon the absorbing and spongy substance. Instead of mounting
the cover or inner plate fixedly, it may be adapted in a moveable manner, like a
slide cover.
In this case the opening for pouring in the liquid, is dispensed with,.
for the liquid is directly put into the hollow back. Other holes may be arranged
in the outer plate like those through which the bristles pass; the liquid will then
also run out through these holes. For the circular brushes the liquid is introduced
through the hollow axle or in any other manner. As to the liquids introduced into
these brushes or brooms, they differ according to their application for hair

may be used. Skin brushes for use from a medical standpoint or for cleanliness,
may be filled with medicinal or soapy liquids of all kinds. Clothes brushes should
be provided with water or any other matter suitable for cleaning, and also with
disinfectants alcohol, benzine, etc. For the nail brushes: antiseptic or soapy
liquids; for tooth brushes: antiseptic or any dentifrice; for carpet and domestic
brooms water, caustic liquids, tinctures, varnish etc.; for boot brushes: blacking
or polishing liquids etc.

I, REGINALD HADDAN of the Firm of Herbert Haddan & Co. of 18 Buckingham
Street, Strand, W.C. London, Patent Agent, do hereby declare the nature of this
invention a communication to me from abroad by Paul Hochet of 24 Rue des Fossés
St. Jacques, Paris, in the Republic of France 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 the construction of hollow backed brushes in which
the frame or back of metal or any other material is hollow forming a chamber its
face plate having holes through which the bundles of bristles pass somewhat
tightly yet without hermetically closing said holes, the said bristles being secured
in holes made in the back plate of the said chamber so that the chamber is adapted
to receive in its interior space antiseptic disinfectant, medicinal or cleansing liquid
for supplying the same to the bristles and thus to the object to which the brush is
applied. The improvements consist in the construction of such brushes and in the
means for regulating the outflow of liquid therefrom.
In the annexed drawings
Fig. 1 is a face view of a brush back or body suitable for a hair brush and
Fig. 2 is a part longitudinal section thereof on line X-Y of Fig. 1 showing
also the bristles and part side view.
Fig. 3 is a cross section and Fig. 4 a side elevation of the plug for closing the
orifice through which the liquid is admitted to the space within the hollow back
and for regulating the outflow of liquid to the bristles as hereinafter explained.
Fig. 5 is a side view partly in section of a nail brush..
Fig. 6 is a similar representation of a tooth brush:
Fig. 7 illustrates a carpet broom and ▸
Fig. 8 a circular brush..
The brush back is made up of three plates-A B and C. Of these the plate A
is a counterpart of the plate B and these two plates form together the chamber
for reception of liquid. The plates A and B are perforated with holes of suitable
shape according to the kind of brush and more or less closely together each hole
in one plate being opposite a corresponding hole in the other. The plate C forms
a cover over the back of plate B. The bristles are inserted in bunches in the
ordinary way and pass through the holes in plate A and through the corresponding
holes in plate B and they are set in or behind-the plate B according to the ordinary
method of setting bristles. The space between the plates A and B has at any
suitable place an orifice surrounded by a flange forming a socket for the screw
threaded plug D. This plug may have a rubber washer for enabling it to close
the orifice hermetically when screwed fully down. In the screw threaded part of
the plug D open several parts or passages d d' d opening freely to the base of the
plug so as to be in constant communication with the space between plates A & B.

page_text: The orifices of these passages are each at a different height that is to say at a
different distance from the washer d' of the plug. It will be obvious therefore
that by partially unscrewing the plug one or more of these orifices may be brought
into free communication with the outer air above the flange of the brush back and
à relative amount of freedom given for air to enter the brush back in replacement
of the liquid which will then be enabled to flow out between the bristles in the.
plate A. When the bristles are brought into movement or deflected by the use
of the brush the liquid is drawn out by capillary attraction and more or less
saturates or moistens the bristles.
In place of using a screw plug D there may be fitted a compressible ball or
bulb for causing outflow of liquid by the higher air pressure produced by its
compression by hand, or such ball or bulb or the hollow back may be filled with
sponge or other absorbent by the compression of which the liquid is ejected. In.
the plate A there may be additional holes through which bristles do not pass.
The plates A and B may be rigidly fixed together by soldering, rivetting or
screwing or the one may slide on or be removable from the other for insertion of
liquid without employment of a plugged orifice.
Having now particularly described and ascertained the nature of this said inven-.
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a hollow backed brush the combination, for the purpose set forth of a
face plate having a plurality of holes therein, a back plate having holes corre-.
sponding with those in the face plate, a plurality of bristle bundles passed through
the holes in the face plate and set in the holes in the back plate, the two.
plates forming a closed chamber having an orifice, and a plug for closing said
orifice.
2. In a hollow backed brush, the combination, for the purpose set forth, of a
face plate having a plurality of holes therein, a back plate having holes corre-.
sponding with those in the face plate, a plurality of bristle bundles passed through
the holes in the face plate and set in the holes in the back plate, the two plates
forming a closed chamber having an orifice, and a plug for closing said orifice,.
the said plug having ports communicating with the interior of the chamber and.
leading severally to points at different heights in the said plug.
