SHELTON, F CAMBRIDGE, MASSACHUSETTS SCALIP-TREATING APPARATUS Application filed January 19, 1927. Serial No. 162,017.

This invention relates to apparatus for treating the scalp.

The invention aims to devise an apparatus of this character which will facilitate the d massaging and heating of the scalp and the application of liquids thereto for any purpose, as for example, in shamptming. In giving an oil shampoo it is preferable to have the oil hot at the time of application to the scalp and to heat the scalp so as to open the pores preparatory to such application. It is a very common practice, also, to massage the s al during and after the application of the oil. The present invention provides a device adapted especially for use in this work, although it is contemplated that it may also be used in treating the scalp in other ways. For convenience the liquid to be applied will be hereinafter referred to as oil, it being understood, however. that this term is used in a generic sense to include any liquid which can be used in the apparatus.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a plan view of a device constructed in accordance with this invention;

Fig. 2 is a vertical. cross-sectional view through the device shown in Fig. 1;

Fig. 3 is a horizontal cross-sectional view of the device shown in Figs. 1 and 2, a part of the handle being broken away;

Fig. 4 is a cross-sectional view on a large scale showing the construction of the teeth or nipples: and

Fig. 5 is a perspective view showing the invention applied to a vibrator.

The device shown in the drawings comprises a body part 2 having a series of blunt ended teeth or nipples 3 projecting from the face thereof. Preferably this face is curved to conform in a general way to the curvature of the head. This part may conveniently consist of a light weight cast metal, such as aluminum, or it may be made of non-metallic pilaterials, such as vulcanite, bakelite,'or the ire.

Mounted centrally in the body part 2 is a. metal container 4 adapted to hold a quantity of olive oil, medicament, or liquid of any kind. The container or reservoir is open at the face of the device and this opening is normally closed by a cover or closure 5 which is screw threaded into the opening. The cover carries a plurality of nipples 6, similar to the nipples 3, andv each of the nipples 6 has a hole or duct formed therethrough to conduct the oil from the reservoir 4 to the scalp.

In order to heat the oil and also the body portion of the device, an electric heating coil 7 is mounted in the body 2 and closely sur rounds the oil container or reservoir 4 so that the heat generated in the coil is conducted very directly to the oil in the reservoir. The body portion of the device also includes a circular fiange 8 which surrounds the heating coil 7 and serves to conduct heat from this coil to the face portion of the device where it is transmitted to the nipples 3. The conduction of heat toward the back of the device is reduced by a washer 9 of heat insulating material, and for this purpose, also, the back piece 10 may be made ofvulcanite or of an asbestos rubber composition which has relatively high heat insulating properties. Transmission of heat to the edge portion of the body 2 is retarded by the air space in which the thermostat is located. The back 10 is secured to the body part by a series of screws, one of which is shown at 12.

The apparatus may be used either with or without a handle, as desired, but incase a handle is used, it preferably is constructed and attached as shown at 13 and is made 1101- low so that the electric conductors 14 which lead to the heating coil 7 may pass through it.

For the purpose of automatically limiting the temperature which the device will attain, I prefer to include a thermostat in the electric circuit. This thermostat is indicated at 1:1. and as shown, is mounted in the annular chamber which surrounds the flange 8. The thermostat is in series with the coil 7, the current flowing through the thermostat to a'contact piece 16 which is adjustable toward and from the thermostat by means of a screw 17 so that the degree of heat employed can be regulated by adjusting the screw. That is, the thermostatic strip 15, as its temperature rises, will tend to straighten and thus break its connection with the contact 16 and open the heating circuit. By turning the screw 17 the contact mav be moved in or out so that the temperature at which the circuit will be broken can be regulated.

In case the body member 2 is made of metal, it is preferable to make the tips of the nipples 3 of some softer material. Such a construction is shown in Fig. 4 in which the tip 18 is made of rubber of the desired degree of hardness and is screw threaded on to the main part of the nipple 3. This construction facilitates the replacement of the tips in case they become worn or become aflected in any wa by the oil or other liquid used.

n using the device itis contemplated that it may be employed both to heat and massage the scalp preparatory to applying the oil. The oil may then be placed in the reservoir 4, the closure 5 screwed in tightly, and the oil then a plied while the massaging is continued. 'Fhe heat generated in the coil 7 quickly warms up'the oil so that it flows through the restricted ducts or apertures in the nipples. The device may also be used to advantage in applying medicaments of various kinds to the scalp.

Under some circumstances it is' desirable to attach the device to a vibrator, and for this purpose the handle 13 is dispensed with, and the back piece 10 is constructed to thread on to the shaft or stud of an ordinary vibrator 20, Fig. 5.

While I have herein shown and described the best embodiment of my invention that I have so far devised, it will be understood that the invention may be embodied in other forms without departing from the spirit or $00 e thereof,

- aving thus described my invention, what I'desire to claim as new is:

1. A scalp treating device comprising a body part having an oil reservoir therein, an electric heating coil surrounding said reservoir, heat insu ating means for retarding the transmission of heat from said coil toward the back of said device, and a pluralit of nipples projecting from the face of sai device for engagin the scalp, certain of said nipples having ucts therethrough for delivering the oil from said reservoir.

2. A scalp'treating device com rising a body part having an oil reservoir t erein, an electric heating coil closely surrounding said reservoir, a removable closure for said reservoir, heat insulating means for retarding the transmission of the heat generated in sai co l toward-the. edge portion and the back of said body, scal engaging nipples proecting fromthe ace of said device, and

ducts for conducting oil from said reservoir to certain of said nipples.

3. A scalp treating device comprising a body part, an oil container separate from said body part and mounted therein, said device having a front wall provided with nipples for engaging the scalp, ducts for conducting oil from said reservoir to the front face of said device, an electric heating coil closely surrounding said container and located in said body part, and heat insulating means at the back of said coil and container.

at. A scalp treating device comprising a body part havin an oil reservoir therein. electrical means for heating the oil in said reservoir, a plurality of nipples projecting from the face of said device for engaging the scalp, restricted oil discharge openings leading from said reservoir to the face of said device, said body part having a space therein between its edge portion and said reservoir, and a thermostat in said space for automatically limiting the temperature generated in said device by said electrical heating means.

5. A scalp treating device comprising a body part having an oil reservoir therein, an electric heating coil surrounding said reservoir, a. removable closure for said reservoir located at the face of the device, said device having nipples projecting from the face thereof to engage the scalp, oil discharge ducts leading from said reservoir to said face, and a heat insulating back secured to said body part.
