Application June 23, 194s, serial No. 34,744 1 claim. (c1. 344.99;

This invention has for one of its objects the provision of a novel and simple hair drier which is adapted to be attached to a vacuum cleaner so that a woman may conveniently dry her hair at home.

Another object is to provide a drier such as described in which a flexible helmet and a conduit attached thereto are constructed and arranged so that the helmet may be comfortably worn with the conduit subject to convenient connection with a vacuum cleaner whereby, air may be blown into and through the helmet to dry the hair of the wearer in a particularly eiiicacious manner.

` Another object is to provide a simple and inexpensive hair drier such as described which is a unit may be readily and easily constructed of the present popular flexible plastic sheet material whereby the drier will be comparatively light as to weight, manufactured at a relatively low cost, capable of properly conforming to and covering heads of various sizes, and particularly comfortable to the wearer. l

Another object is to provide a hair drier such as described in which is embodied a novel form of filter to eliminate any dust or foreign matter which may be present in the air stream being directed into the helmet from a vacuum cleaner.

Another object is the provision of a simple and efficient mechanical means associated with the conduit for causing the vacuum cleaner to supply heated air to the helmet and thus accelerate drying of the hair.

We will describe only one form of hair drier embodying our invention, and will then point out the novel features thereof in the claim.

In the accompanying drawings:

Fig. 1 is a perspective view showing one form of hair drier embodying the present invention applied to a vacuum cleaner and to the head of a user.

Fig. 2 is a front elevation of the helmet as in use.

Fig. 3 is an enlarged fragmentary sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a top plan View of a modified form of the drier.

Fig. 5 is an enlarged sectional View taken on the line 5 5 of Fig. 4.

Fig. 6 is an enlarged fragmentary sectional view taken on the line 6--6 of Fig. 5.

Referring to the drawing more specifically 'l generally designates a flexible helmet constructed so that it will provide ample room around the head of the wearer to alford a free circulation of air through and about the hair to quickly dry the hair and 8 generally designates a. flexible conduit attached to the back of the helmet and adapted to be connected to a blower or the like for suplying air under pressure to the helmet. As here shown an ordinary vacuum cleaner 9 serves as a blower and the conduit as here provided is adapted to be readily connected to various makes of vacuum cleaners whereby the drier may be conveniently operated in the home.

The helmet and conduit are made of impervious and flexible sheet material whereby thedrier will be comparatively light and capable `of being readily folded into very small compass for convenient packaging, storage and shipment. Preferably a flexible sheet plastic now available on the market and which is `somewhat elastic, waterproof, highly exible and capable of having pieces or sections thereof joined or seamed by means ofheat and pressure or if need be by means of stitching, is used in making the helmet duit.

. As here provided the helmet is formed with a somewhat Vcylindrical body I0 having its oneend open and provided with an elastic puckering string as indicated but not specifically shown in Fig. 1, whereby the margin II of said open end will be drawn closely to conform to the head of the wearer about the forehead and back of the neck and above the ears as shown in Figs. 1 and 2. The top of the cylindrical body I (l of the helmet 'I is closed by a crown I2 as here shown made of two pieces or sections. The body Il) and crown I'2 are so dimensioned that there will be provided a hair drying chamber alfording ample space for the ycirculation of air in the helmet for effectively drying the hair..

The body I0 ofA the helmet is provided at the front thereof with air outlet means here shown as a plurality of openings I3 which are preferably covered with flexible screens I4 to prevent the hair from protruding through the openings. In the back of the body I0 of the helmet is an air intake opening I5 through which the conduit 8 communicates with the interior of the helmet, said conduit being joined to body about the margin of the intake opening as shown at I 6.

Attached in any suitable manner to the body I0 inside the helmet so as to extend over the intake opening I5 is a filter generally designated I'l for screening out any dust or foreign matter which may be present in the air stream passing through the conduit. This filter as here shown may Y consist of opposed and spaced flexible screens I8 held in a exible frame I9 of the same 3 material as the helmet and holding therebetween aller 20 of a porous and soft filtering material,

as best shown in Fig. 3.

As shown in Fig. l, the intake end 23 of the conduit 8 may readily be tted over the nozzle 2| on the usual flexible hose 22 of a vacuum cleaner of the type provided with such parts, said intake end being provided with an elastic puckerin'g or draw string as indicated butnot specifically lshown on Fig. 1. This formation of the intake end also makes the conduit readily attachable tothe exhaust or blower ends of As shown in various makes of vacuum cleaners. Fig. 1 the hose 22 has been applied to the exhaust end of the vacuum cleaner'so that Vthe cleaner will blow air through the hose and However, it is possible to vdraw air..Y

helmet. through the helmet for drying the hair, in which case the hose 22 is connected as for theusual vacuum operation and air is taken in through the openings.13thendrawn through the helmet, theopening I andthe conduit 3Y anddischarged through the vacuum cleaner.

1 Asshown in 1igs.,4:andv 5, thelexible conduit 8, may;v have its intake end 23v fixed directly to a; coupling member, 24-which may bescrewed.

int'oa tubular. and tapered tting 25 subject to insertion into thel discharge end of theA vacuum cleaner; In this, arrangement the. coupling 24 is provided with alter unit 26 forpreventng dust and; foreign -matterfrompassing through the conduit to the helmet.

' Fig. 6l shows how the intakeend of the vacuum cleaner may have anv apertured and flanged disk.211tted.thereover to; restrict the intaking of airy such that the motork of theY vacuum will become heated and, therefore, heat the air being suppliedto the helmet, thus accelerating the drying ofthe hair.

,This disk2l has acomparatively small fintake. aperture 28 therein so that the ,relatively small. volume of air permitted to pass therethrough will.

Y the purpose above noted. The disk 21 may be All impose a load on theinotor of the. vacuum cleaner. and Ythus .cause `the motor to heat upfor1V employed in the vacuum cleaner arrangement shown in Fig. 1, as well as with the arrangement shown in Figs.` 4 and 5, and in fact in any other type of vacuum cleaner to which the drier hereof is applicable.

Although We have herein shown and described only one form of hair drier embodying our invention, it is to be understood that various changes and modifications may be made therein v:without departing from the spirit of the invention and the spirit and scope of the appendedV claim.

We claim: v The combination with a motor driven vacuum Acleaner and a helmet for forming a hair drying chamber about the head of the wearer, of a conduit for delivering air under pressure from said vacuum cleaner to said helmet, and means for restricting the intakingv ofY air into said vacuum cleaner to suchrextent that `the motor of the cleaner will vbecome heated and heat the Yair discharged thereirom intoA said` conduit.
