Description
June 2, 1936. a, DUCART HOOD FOR DRYING HAIR Filed June 21, 1935 //v v /vroe 40/45 300/927 Patented June 2, 1936 UNITED STATES PATENT OFFICE K!) FOR DRYING HAIR Guillaume Ducal-t, Paris, France Application June 21, 1935, Serial No. 27,881
4 InFrance July 17, 1934 'icinm (eta-2a) The invention relates to a hood for drying hair and which possesses numerous advantages over 15 or arms of which are arranged in such a way that during their rotation they describe a surface of revolution preferably hemispherical which encloses the hair to be dried.
It will be easily understood that by arranging thefan around the head of hair, the latter is aired and dried without the hot air having to pass through a duct or a distribution chamber.' Consequently the hot air is more effectively utilized without losses by radiation and the noise ordinarily produced'by the circulation of the air through the said distribution chamber and ducts is avoided.
In order to make the invention more clearly understood and by way of non-limiting construcm tlonal example, one embodiment of such a hood dryer is hereinafter described 'and is illustrated diagrammatically 'in the accompanying drawing, 2
to which reference will be made.
In this drawing: Figure 1 is a diametral sectional'view of the hood and a part of its supporting foot, certain of theparts being shown in elevation. t Figure 2 is a side view of the hemispherical an. 4) Figure 3 is a top plan view of this fan. Figure 4 is a view similar to Figure l and shows a modification in the drive of the fan.
In these figures, l is an outer casing in the form of a hemispherical cup, 2 is an inner casing 4,5 of similar form and the base of which engages upon the-base of the first casing so that an empty space serving for the lodgment of the fan is formed between the two casings.
According to the invention this fan comprises 50 blades 3, arranged in such a way that during their rotation they describe a surface of revolution which encloses the hair. For this purpose the fan is constituted by a body 4 having the shape of a hemispherical bowl in which are 1 formed the blades 3 which are curved in the direction of rotation thereby giving a uniform and silent air flow.
- The hemispherical bowl 4 is surmounted by a cylindrical part 5 forming the boss of the tan and closed atthe lower part by a conical base 6 6 at thecenter of which is provided a bearing for mounting the fan on the electric driving motor I.
In the chamber 5 is housed the motor I, the shaft I6 of which is secured to the boss 5 by means, for example, of nuts l1 and I8 between which the 10 'base 6 is tight. Between the periphery of the motor 'I and the internal wall of the chamber 5 is provided a space permitting air to circulate.
The motor 1 is provided with orifices IS on its rear casing and, between the armature and the 16 field magnet system 'l' yare provided passages 20 permitting air to circulate inside the motor;
By means of this arrangement, the motor is cooled in a particularly efiective manner. A switch B'is provided for starting and stopping the go motor I.
The air enters e space comprised between the two casings l and through orifices controlled by regulating plates 9 and provided upon the outer casing l which has a plain wall. The inner cas- 2:; ing 2 is, on the contrary, provided with a large number of perforations I0 and for this purpose it is formed of a perforated plate or of expanded metal or of metal trellis (as shown in Figure 4) or gauze or in any similar manner. 80
During its rotation, the fan 3 draws air through the motor I and the boss casing B keyed upon'the shaft of the motor; and also through the adjusta-. ble apertures 9, and is made to pass over a heating resistance Ii, and is then projected through 36 the perforations ill in the inner casing 2.
A depression is produced at the apex of this casing 2 which draws in hot air saturated with water vapour in order to make "it pass through the fan again, thereby recuperating the heat con- 40 "tained in this air without any danger of the water vapour coming into contact with the electric motor I which is protected by the boss casing 5, which is itself under depression.
This is due to the fact that, owing to its shape, 4 the fan 4 has a greater outpart at the level of its larger circle or' base circle 4 than at the level 5 where the blades 3 are set in, whence the result is an increasing output from 5 towards 4, thus creating in 5' a depression, the more so high that the diilerence between the diameters and 5' is greater.
' The pressure created between the fan 4 and the outer casing l flows towards the base of the hood, giving rise, between said fan and the human head 2|, to a strong draught altogether giratory and ascending towards the point 5. From said point, the air is taken anew and mixed to the hot air out flowing from the resistance II. The excess otair due to such a working modus is automatically expelled at the base of the hood, at 22 thus creating around the head 2|, owing to its giratory motion, a cooling zone preventing any over-heating of the head. 7
It is to be noted that, due to its rotation, the fan 4 causes the ascending and descending eddies currents to set apart The apparatus is carried by a foot I! upon which it is pivotally mounted by means of the hand grip M which is mounted in a yoke l5 provided at the upper end of the said foot.
It is clearly understood that without going outside the scope of the invention, modifications and improvements of details may be made and that equivalent means may be employed.
For example, the electric heating resistance may be replaced by a gas burner arranged externally.
According to the modification disclosed in Fig.
4, the actuating motor 1 is set apart from'thehood, the Ian being driven through a flexible cable or shaft 23.
I claim:-
1. A hood for drying hair comprising a hollow casing of dished form, and a rotatable fan within said casing and comprising blade elements also of dished form adapted to describe a surface of revolution which surrounds the hair to be dried during rotation of the fan.
2. A hood for drying hair comprising ahollow casing formed by two dished casing elements arranged one within the other in spaced relation, and a fan rotatable in the space formed between said casing elements and also being of substan tially the same dished form as said casing elements.
3. A hood for drying hair comprising a hollow casing of dished form, and a fan rotatable within said casing and being 01' substantially hemispherical form. x
4. A hood for drying hair comprising a hollow casing formed by two dished casing elements arranged one within the other in spaced relation, and a fan rotatable in the space between said elements and being formed by a dished plate the surface of which is cut out and expanded intermediate its apex and periphery to form fan blades.
