COMPLETE SPECIFICATION.
A New or Improved Device for Supplying Oil, Lotions, or the like
to the Scalp or Hair.
I, ERNEST BISHOP of Heath House, Perranarworthal in the County of Cornwall,
Gentleman, 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 a new or improved device for supplying oil lotions or the
like to the scalp or hair by means of which certain advantages are obtained.
In order that my invention may be readily understood I shall proceed to describe
by way of a type or example one form in which it is to be or may be carried into
practice; and in order that the said form may be more clearly grasped I have
appended hereto a sheet of drawings illustrating the said form and also a
modification of a part thereof.
In the said drawing,
Figure 1 is an elevation partly in section of the form herein before mentioned.
Figure 2 is a transverse section on the line 2 to 2 of Figure 1, and
Figure 3 is a transverse section on the line 3 to 3 of Figure 1.
In the said figures 1 is a comb similar to those ordinarily employed as hair
combs; but it differs therefrom in that instead of being solid throughout as ordinary
combs are it is constructed with passages or ducts for the purpose hereinafter
mentioned. 2 is the handle of the said comb. This handle which may be formed
of any suitable material such for example as wood, metal, celluloid or the like
is hollow and contains within it a bag or bladder 3 of soft rubber. This bag or
bladder I shall hereinafter for the purposes of this specification term the reservoir.
It is designed to contain oil, perfume, lotion or any other liquid which it is desired
to apply to the hair or scalp. This reservoir communicates in the manner
hereinafter described with the canal 4 which is formed in the back of the comb
proper. From the said canal ducts 5 pass through the teeth of the comb. These
ducts extend to the points or extremities of the teeth and end in minute orifices 6 as
will be seen in the drawing. The nozzle or end 7 of the reservoir protrudes from
the handle into the canal as shown when the parts are in their normal position.
The handle with its contained reservoir is screwed to the comb proper by means
of the threaded ferrule or union 8. 9 is a screw-down valve or pinch-cock of any
convenient description which serves when screwed home to compress the neck 10 of
the reservoir and so prevent its contained liquid from escaping or passing out.
11 is an aperture formed in any convenient part of the handle which exposes the
reservoir and enables it to be reached by the finger when thrust through the said
orifice.
The action of this form of my invention is as follows:-
.Let us assume that the reservoir is filled with liquid, hair-oil for example which
it is desired to apply to the hair. The binding screw 9 is first loosened to allow a
free passage of the hair-oil from the reservoir. The comb is now used in the well
known ordinary manner but at the same time one of the fingers is inserted through
the aperture 11 and caused to press upon the reservoir 3. The reservoir 3 is thus
compressed and part of the oil therein is ejected through the nozzle 7 into the
canal 4 from which it passes through the ducts 5 and orifices 6 to the hair or scalp.
The hair can thus be oiled without soiling the hands. When no further ejection of
oil is required the finger is withdrawn from the aperture 11 and the pressure

page_text: removed from the reservoir. The elasticity of the sides of the reservoir now causes
any drops which may be hanging from the orifices 6 to be withdrawn into the ducts
so that no-oil remains to drip on other objects. The valve or pinch-cock 9 can now
be screwed down when no further oil will escape from the reservoir. The
reservoir 3 can easily be filled when required by unscrewing the handle at the
union 8, compressing the reservoir and then removing the pressure thereon whilst
the nozzle 7 is dipped in a vessel of hair oil. In other words the reservoir can be
replenished in the same manner as is the filler used in the case of ordinary reservoir
pens for replenishing the same with ink.
Figure 4 shows in longitudinal vertical section a tooth and part of the back of
the comb proper of a modified form of my inventiou. This form differs from that
hereinbefore described solely in the fact that the duct 5 instead of passing to the
extremity of the tooth leads to an orifice 6 at the side thereof.
1 desire it to be understood that I do not limit myself to the form or forms of my
invention hereinbefore described. Any competent person having grasped the spirit
of my invention will be able to modify the form and details thereof to an indefinite
extent.
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 :-
1. In a comb the employment of canals ducts or passages substantially as and for
the purpose set forth.
2. The combination of a comb proper fitted with canals ducts or other passages
and a reservoir for liquids substantially as set forth.
3. The combination of a comb proper provided with canals, ducts or other
passages, and a reservoir for liquids the said reservoir being contained in a
detachable handle substantially as set forth.
4. The combination of a comb proper, provided with canals, ducts or other
passages, a reservoir for containing liquids and a pinch-cock or its equivalent
substantially as set forth.
5. The arrangement and combination of parts substantially as set forth with
reference to Figure 1.
6. The modification set forth with reference to Figure 4.
