SCALP COOLING DEVICE

BLANCHE B. COLE

Patented December 6, 1938


This invention relates to improvements in scalp cooling devices particularly adapted for use in cooling the scalp adjacent permanent waving heaters.

The principal object of this invention is the provision of a simple and conveniently operable scalp cooling device whereby the cool air may be quickly and definitely directed to the overheated portion of the scalp to immediately relive the objectionable heated condition.

A further object of this invention is the provision of a scalp cooling device having an applicator with offset lips whereby the flow of cool air may be properly directed to the desired portion of the scalp.

Other objects are economy and simplicity of construction, ease and rapidity of manipulation and adaptability for use with the various types of hair treating attachment.

Reference will now be had to the drawing, wherein:

Fig. 1 is a perspective view of a scalp cooling device, n operation, embodying this invention.

Fig.2 is an elevation of the applicator.

Fig. 3 is a central sectional view of the applicator taken of line III-III of Fig. 2.

Fig. 4 is a sectional view of the applicator taken on line IV-IV of Fig. 3.

Fig. 5 is a perspective view of the chair clamp with a cooler hood secured therein.

Throughout the several views of the drawing, similar parts are designated by like numerals and 10 designates a motor of any suitable type to drive a fan or air pump 12 which delivers air through the flexible tube 14 to the applicator 16. The motor and fan may be on a common base, as shown, and are adapted to be placed in any convenient position on the floor adjacent the work, so that the operator may control the operation of the motor by means of the foot switch 18, which is preferably built in the motor unit.

In the operation of this device, the customer A is seated in chair C and the permanent waving apparatus 20, including heaters 22, are positioned so as to heat the hair for permanent waving in the usual manner. Due to defective hearers, steam sometimes escapes from the heaters and causes a burning to the scalp therebeneath, and it is to overcome this objectionable scalp burning that the present cooling device is provided.

A chair clamp 25 comprising a resilient U-shaped member 26 adapted to grip the back chair member is provided with clamping fingers 28 between which the tube attachment may be placed to secure them against dislodgement when not in use.

An internally positioned coupling tube 30 serves to interconnect the flexible tube 14 with the applicator 16. Applicator 16 is shown, as molded form a suitable material such as rubber, with a handle 32 adn a flared nozzle portion 34, shape with the orifices 36, thereof, elongated and communicating with the opening 38 formed through applicator 16. The lower lip 40 of nozzle 34 is concave and protrudes beyond the upper lip 42 as clearly shown in Fig. 2 and 3.

When air is forced by pump 12 through tube 14, sleeve 30, handle opening 32, it will be discharged through orifice. The object of this device is to direct cool air to the scalp at a point adjacent a hair treating heater that has through leakage of steam therefrom caused an uncomfortable heating of the head. These heaters are elongated adn when in operation are slightly are obtained when the cool air is directed from the scalp so that the best results are obtained when the cool air is directed from below the heater upwardly between the heater and the scalp, thereby driving the accumulated steam form its position, tending to cool the head and also the curling apparatus.

To properly apply the cool air the applicator is pressed against the head below the objectionable heater, with the lip 40 contacting the scalp and lip 42 spaced apart therefrom, thus driving the air upward between the heater and the scalp. The lower lip 40 serves as a dam to preclude a downward escape of the air, also the restricted orifice will cause a substantial distribution of the air throughout its length.

After the hair has been properly heat treated, it may be cooled by use of the head canopy 46 which is connected through the rigid tube 48 and flexible tube 14 to the air pump 12. This head canopy serves to properly direct and distribute the air, furthermore, a means for heating the air thus used might be provided.

It is very apparent that this type of foot control motor and air pump is suitable for delivering air to any type of applicator that might be used in the various hair treating operations.

What I claim is new and desire to cover by Letters Patent is:

1. In a scalp cooling device of the character described, an applicator inter-connected by a flexible tube to a source of air and having an elongated narrow orifice between offset lips, whereby when one of said lips is contacting the scalp the other of said lips will be spaced apart from the scalp to permit the flow of air therebetween.

2. In a scalp cooling device of the character described, an applicator having a hollow handle, adapted to receive air from a source of compressed air, an elongated, concave nozzle communicating with said hollow handle and having spaced apart, offset lips to form a relativ narrow orifice whereby when said applicator is positioned substantially perpendicular to hte surface of the head one of said lips will contact the scalp while the other lip will be spaced apart from the head, to direct air along the surface of the scalp.

3. In a scalp cooling device of the characters described, an applicator having a hollow handle, adapted to receive air from a source of compressed air, an elongated, concave nozzle communicating with said hollow handle and having spaced apart, offset lips to form a relative narrow orifice whereby when said applicator is positioned substantially perpendicular to the surface of the head one of said lips will contact the scalp while the other lip will be spaced apart from the head, to direct air along the surface of the scalp.

4. In a scalp cooling device of the character described, an applicator having an elongated hollow handle portion communicating with a transversely disposed nozzle portion , said nozzle portion being elongated and having two offset, spaced apart lips concaved toward said handle, whereby one of said lips will contact the curved scalp while the other lip is spaced apart therefrom.

5. In a scalp cooling device of the character described, an applicator having an elongated hollow handle portion communicating with a transversely disposed nozzle portion, said nozzle portion being elongated and having two offset, spaced apart lips concaved toward said handle, whereby one of said lips will contact the curved scalp while the other lip is spaced apart therefrom and the portion of said handle adjacent said nozzle being restricted in cross section.
