COMPLETE SPECIFICATION.
Apparatus for Drying Hair and other Filamentary Bodies.,
I, JOSEPH ETIEnne PrégardieN, Engineer, of 19'Neuböfferstrasse, Cologne
Deutz, in the German Empire, 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 :-
--
The appliances hitherto known for drying hair or the like have been constructed
of a comparatively large size and were unsuited for private use, inasmuch as the
assistance of a second person was always necessary to operate them. Their
construction was, 'besides, very complicated, and it was an expensive matter to keep
them in repair.
It is the object of the present invention, to obviate all these drawbacks, by
providing improved apparatus for drying hair, capable of being used by any one
person, privately and independently of any outside assistance, in drying his or her
own hair. The apparatus is, moreover, extremely easy and convenient to handle,
being of small weight, neat and clean.
The apparatus is fit for use however, not for drying hair only, but for drying a
variety of other materials consisting of long fibres, such as yarn, wool and
the like.
The invention will be best understood by reference to the accompanying
drawings, Figs. 1 to 9, in which the improved apparatus is shown in various
modifications, each being represented in longitudinal section and in cross section.
A casing a, provided with an exchangeable handle, has on its working surface
hollow projections 6' communicating with the interior of the casing.
The shape, sectional area and size of the casing and of the projections b
depend upon the particular purpose for which the apparatus is to be employed in
any given case.
In the form shown in Fig. 1 the apparatus assumes the shape of a brush, and
the projections have the shape of short conical tubes.
Fig. 2 represents the apparatus in the shape of a comb, the back or support of
which is formed as a receptacle, while the teeth form the projections above
referred to.
Fig. 3 is still another form of the device of the same class, in which the several
knife-shaped projections are arranged in a row.
Various other forms may be given to the improved hair drying apparatus,
without departing from the principle of the invention.
Figs. 4 to 9 represent apparatus constructed on the same principle, but of
circular or annular cross-section, and provided either along the whole of their
periphery, or upon a part thereof, with hollow or solid projections, as the case
may be. These projections may either, as before mentioned, take the form of
conical tubes, or that of hollow discs (Figs. 6 and 7) or of solid dises (Figs. 8
and 9). In apparatus of this configuration, the receptacle a, together with the
projections b, serves for the reception of the heating medium employed, the heat
of which is directly communicated to the several projections, or in other words to
the operative surface of the apparatus.
When this receptacle or vessel a is of annular section, the inner part thereof
may serve for the reception of a heating agent, while the annular portion may
receive the medium employed for the transmission of heat.
The most convenient source or medium of beat would be hot water admitted

page_text: into the interior of the apparatus through an orifice a³ provided with suitable
arrangements for closing it. Other heating agents, however, may be employed,
due care being taken, that the heat thereby diffused is distributed among the
various operating surfaces in an even and uniform manner..
The surface of the casing or body of the apparatus may, if required, be provided
with an outer envelope or jacket for reducing the waste heat.
Instead of the hollow projections, solid ones may be employed, if need be.
It is also possible, to employ a smooth receptacle or vessel, or a solid body with
an even outer surface, but in that case the useful effect of the apparatus would, of
course, be a good deal reduced.
The operation of the improved hair-drying device will be readily understood by
reference to the drawings. The hair or the like to be dried is simply taken in
one hand, while the apparatus, held in the other hand, is passed through it, the
projections or teeth acting much like the teeth of a comb. Owing to the contact
of the heated surfaces with the hair or the like, the drying process is rapidly and
thoroughly completed.
If desired, the apparatus may be stationary, without a handle, in which case
the material to be dried must be passed through or between its teeth or
projections.
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
1. Apparatus for drying hair and other filamentary bodies, chiefly comprising a
vessel provided with hollow or solid teeth or other projections extending from
its working face, and (for ordinary purposes) with a handle, the whole being
arranged and adapted to operate substantially as described and illustrated by the
drawings.
2. The various forms of hair-drying apparatus shown by the drawings.
