SCALE-TREATMENT DEVICE.

Application filed January ment or pin of the brush has the same polarity, while the other pole of the current is usually applied through an electrodeheld-in the hand of the person undergoing the treatment. The application of electric currentin this manner is likely to provevery disturbing ,to the nervous system, sincethe current seeking the line of least resistance through the entire body will pass through the more delicate and vital organs. g I

It is the object of my present invention to provide for administering electrical scalp treatment of this sort without disturbing the deeper seated delicate nerves or organs.

Another object is to provide for applying the electric current solely through the scalp and independently of the remainder of the body. 1

Another object is to break the circuit through the scalp into a plurality of circuit connections which, with the avoidance of the deeper seated delicate nerves and organs and the confining of the treatment currentto the scalp, gives armild stimulation-without the sharp sting orshock experienced with the former devices and methods. 1 I

Another object is:to, provide a generally improved andsimplificd construction that may be economically produced, and a device in" which the electrodes and otherpartsv may be readily cleaned and sterilized, without dis-.

turbing the wiring or circuit connections. U

To acquaint those skilled in the art with the manner of constructing and practicing my presentinvention, I shall now-describe in connection with the accompanying drawings, a particular embodiment of the same.

In the drawings i Figure 1 is aside elevational view of an embodiment of the invention;

Fig. 2 is a view of the bottom or under side of the device as viewed in Fig. 1; I

showing the circuit connections between the conductors and the electrodes of the device.

Referring to the drawings, the particular device selected toflillustrate' the construction and manner of practicing the present invention comprises a handle 5, a back member 6, and a pair of electrodes 7 and 8.

The electrodes 7 and 8 each comprises a metal or other suitable conductingstripha'vmg a connecting or back portion 10 anda. plu rality of integral teeth 12.-v The upper connecting or back portions 10 of the electrodes 7 and 8 each have relatively short longitudinalextensions 14 at one end and at itsoppositeend each back portion 10 has a lon itudinal extension 15 of somewhat greater ength. The extensions 15 form contact ends for connecting the circuit through the electrodes,

and theextensions 14 form retention means at the opposite end, as will hereinafterappear. I Y

The main back member 6 is formed of suitable insulating material such as hard rubber. The back member-6 is of circular cross section threaded externally at its outer end at 18 to receive an end cap 20, and extending longitudinally, through the back member v6 from end to end is a slot 21 for receiving the back portions 10 of the comb or electrode members 7 and'8. The electrodes? and 8 removably mounted in, the back member-6, are insulated from each other therein by means of an insulating, strip 25 interposedbetween the back portions of the electrodes and extending throughout the lengths thereof. I Carried b the back memberz6 at the inner end ofeac electrode is acontact clip 28 for connecting thecircuit conductors 29 one to each electrode 7and8.

The clips 28 are-of angularv formation with one leg of each lying internally along each of the opposite sides of the slot 21, and the other legs turned out'over the inner end of the back f 6. The clips 28 maybe securedby screws 30 and the conductors 29 may be connected to their respective clips through-these screws f orby soldering-the conductor wire, or otherwise connecting it to the inner laterally turned end 32 of the clip. When the electrodes 7 and 8 are mounted in the slot 21 the inner extensions 15 thereof "fit tightly between and firmly in contact with the longitudinally Fig. 5, thereby connecting one electrode to each contact or clip member. The extensions 15 maybe tapered or thinned slightly, so that the back portions 10 will fit snugly in the slot 21 and at the same time the extensions 15 will fit between the clip members 28.

With the electrodes mounted in the back member and connected to the conductors 29 and insulated from each other, the inner extending end of the back member with the electrode extensions 15 are telescoped into the outor tubular or socketed end of the handle 5. The back member 6 may be additionally secured-in the handle by a screw 36 threaded radially through the tubular or socketed end 35 of the handle, and into a registering opening in theiback 6. The cap member 20 is threaded upon the outer end of the back 6 over the electrode extensions 14, finishing the outer end of the device and holding the electrodes and back member firmly together.

The conductors 29 may extend out through the opposite end of the handle 5 and be pro vided at their opposite ends with suitable connectors 40 for connecting the electrodes through a co-operating connector 12 with a suitable source 01 current, which may comprise a suitably housed iaradic or galvanic circuit or the device might even be connected through a suitable rheostat with the usual 110 volt Edison outlet. Threaded into the end of the handle 5 from which the conductors 29 extend, is a nut 45, and a coiled spring 46 se cured tightly about the conductors 2%) at 4t? and secured at its opposite end in the nut minimizes the movement of the conductors in the handle and takes the stresses and wear oil of the conductors and oil of the connections between the conductors and the clips 28, pre venting accidentally pulling the wires out or breaking the connections in the use out the device and its movement into dill erent positions.

The teeth 12 oi the electrodes and 8 are preferably turned or converge at 50 (Fig. to dispose the freeends of the teeth 12 in a. common cent 'al longitudinally extending plane at 52. The teeth 12 of one electrode are preferably staggered with respect to the teeth 12 of the other electrode, so that the teeth of one will engage between the teeth oiithe other and, in elfect, a plurality of alternate dissimilar poles will be provided from one end of the comb to the other. The lower edges or ends of the teeth 12 may be finished on an are, as shownat 55 in Figs. 1 and 3, or this may, of course, be varied as desired.

In use the device is connected to the direct or other current source and the teeth of the comb are brought into co-operation with the scalp and hair. Tlie current thereupon passes from one electrode to the other through the upper tissuesfionly, that is, through the scalp, hair and adjacent parts without passing through the other parts of the body, more especially the delicate and vital organs, as is the case-where one electrode only is applied to the scalp and the other held in the hand.

The staggering or ofi'setting of the teeth oi. the electrodes and their setting in alignment with each other or in a common plane in elfectbreaks the circuit through the scalp into a plurality of circuit connections in parallel with each other, which with the avoidance of the delicate nerves and other organs and the confining of the treatment current to the scalp, gives an exceedingly desirable stimulation without the sharp sting or shock ex perienced with the former devices and methods. Y

The structure is improved and simplified. It may be inexpensively produced and it permits convenient cleaning and sterilization of the two electrodes and other partso't the dev1oe.

20 is removed and then by loosening the screw 36 the entire back with the electrodes carried thereby may be withdrawn from the handle The two electrodes may then be removed troin the slot 21 in the back'member 6, and with the other parts cleaned as desired. To reassemble, the electrodes are placed back in the slot 21 in contact with the clip members 28 and with the insulating strip 25 between them, the back with its electrodes again secured in the'handle and the end cap thread ed upon the outer end of the back member and over the electrode extensions 14.

While I have described my invention in connection with an electric comb, it is tobe understood that it may be embodied in a brush or other scalp treatn'ient device, and I do not intend to be limited to the precise details shown or described.
