page_text: A Method of and Apparatus for Drying the Hair.
JAMES MCKENZIE DAVIDSON Bachelor of Medicine and Master of Surgery,
Ophthalmic Surgeon residing at 343 Union Street Aberdeen do hereby declare the
nature of this invention to be as follows:-
My invention relates to a new method of drying the hair-especially long hair-
after the head is washed or shampooed.
It consists essentially of
-
(1) Air (preferably heated) being forced along a tube by means of a foot
bellows (or any other convenient means)."
(2) An apparatus for heating the air.
(3) A hollow comb with small holes in different positions on the teeth & on the
back of the comb, & this is connected by means of a flexible tube to the pipe
supplying the hot air, so that in this way the heated air issuing from the small holes
under pressure while the hair is being combed leads to its (the hair) being dried
without the unpleasantness of the hard & frequent rubbing with towels as at
present.
I do not confine my invention to a hollow comb perforated with holes but would
employ any shape or form of instrument perforated with holes or by means of slots
or other orifices suitable for the purpose.
For example a brush with a hollow handle & back having perforation or
openings hetween the bristles or wires of the brush & in this way small streams of
air will diffuse through the hair while it is being brushed.
In carrying out the invention the air may be heated in any convenient manner
but I have used the following arrangement which is effectual. A small copper
cylinder has one end permanently closed except at the centre from which issues a
small copper tube. The other end has a cap which screws on to the end & in the
same way as before a small tube issues from the centre of the cap. The interior
of the cylinder is packed with iron wire-the end unscrewing enables this wire to
be changed if desired. A small buusen flame supplied from an ordinary gas
bracket heats the cylinder & when the air is forced through it, the iron wire so
greatly increases the heating surface that a large quantity of air passing through
is rapidly heated with a small expenditure of heat-producing material (gas,
spirit &c.).
The handle of the comb, brush "&c. is connected by means of a flexible tube (well
vulcanized india rubber tubing does well) to the pipe supplying the hot air.
The heat of the air can be regulated easily by heating more or less the "heater."
The rapidity or strength of the air coming through the comb &c. is regulated by
the bellows & c.
I do not confine my invention to any special forin or material for the heater.
I also may interpose a dessicator as well such as a tube or vessel containing
calcium chloride.
The air need not be heated-especially in warm weather and this would render the
apparatus for supplying the air to the combs &c. simpler.

page_text: I, JAMES MCKENZIE DAVIDSON Bachelor of Medicine and Master of
Surgery Ophthalmic Surgeon, residing at 343 Union Street, Aberdeen 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 method of drying the hair especially long hair
after the head is washed or shampooed.
It consists essentially of
(1) Air (preferably heated) being forced along a tube by means of a foot
bellows blower or fan (or any other convenient means).
(2) An apparatus for heating the air.
(3) A hollow comb with small holes in different positions on the teeth and on
the back of the comb and this is connected by means of a flexible tube to the
pipe supplying the hot air, so that in this way the heated air issuing from the small
holes under pressure while the hair is being combed leads to its (the hair) being
dried without the unpleasantness of the hard and frequent rubbing with towels as
at present.
do not confine my invention to a hollow comb perforated with holes but would
employ any shape or form of instrument perforated with holes or by means of slots
or other orifices suitable for the purpose. For example a brush with a hollow
handle and back having perforation or openings between the bristles or wires of the
brush and in this way small streams of air will diffuse through the hair while it is
being brushed. In carrying out the invention the air may be heated in any
convenient manner but I have used the following arrangement which is effectual.
A small copper cylinder has one end permanently closed except at the centre from
which issues a small copper tube. The other end has a cap which screws on to the
end and in the same way as before a small tube issues from the centre of the cap.
The interior of the cylinder is packed with iron wire or metal tubes the end
unscrewing enables this wire or tube to be changed if desired. A small bunsen
flame supplied from an ordinary gas bracket heats the cylinder and when the air is
forced through it, the iron wire or tubes so greatly increases the heating surface
that a large quantity of air passing through is rapidly heated with a small
expenditure of heat producing material (gas, spirit &c.).
The handle of the comb, brush &c. is connected by means of a flexible metallic
or vulcanized india rubber tube to the pipe supplying hot air.
.
The heat of the air can be regulated easily by heating more or less the
"heater."
The rapidity or strength of the air coming through the comb is regulated by the
bellows, blower or fan.
I do not confine my invention to any special form of material for the heater.
I also may interpose a dissicator as well, such as a tube or vessel containing
calcium chloride.
The air need not be heated especially in warm weather and this would render
the apparatus for supplying the air to the combs &c. simpler.
To enable my invention to be fully understood: I will describe how it can be
carried into practice by reference to the accompanying drawing in which
Fig. 1. is a sectional elevation of the comb.
Fig. 2. is a plan of the comb.
Fig. 3. is an enlarged sectional view of the comb tooth.
Figure 4 is the hosting onlinder

page_text: (A) is a tubular connection through which the hot air is conveyed to the comb
the air being carried from the heater by a flexible metallic or other tube (B) is
the tubular back of the comb which conveys the air to the hollow perforated
teeth (C) of the comb, (D) is the copper cylinder the interior of which is packed
with iron wire or metal tubes (E) is the cap screwed to one end of cylinder
for the purpose of inserting or removing the wire or metal tubes (F) is the air-
inlet from the bellows, blower or fan (G) is the outlet for the heated air which is
connected by the aforesaid flexible tube to the comb.
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 :-
1st. The means of producing a constant current of air by a bellows, blower
or fan:
2ndly. An apparatus for heating the air as it passes from the bellows, blower or
fan to the perforated comb or brush.
3rdly. A hollow comb or brush for applying and distributing the air to the hair
or material to be dried.
