Application June 30, 1950, Serial No. 171,342

1 Claim. I (Cl. 128-393) This invention has to do with electric combs, and has as an object the provision of an improved electric comb capable of effectively stimulating and giving life to the hair.

It is a further object of the invention to provide an electric comb in which a continuous electrical circuit is passed through the comb teeth. I

Another object is to provide a comb of this character wherein the circuit carrying wire is carried by insulative comb teeth in such manner as to expose the wire to contact with the hair along one edge of each tooth.

Other objects and advantages of the invention will appear hereinafter.

Without intending thereby to limit the broader scope of the invention, as defined by the appended claim, we shall now describe, in detail, a present- 1y preferred embodiment thereof, for which purpose reference will be made to the accompanying claim, wherein:

Fig. 1 is a side elevation of our improved electric comb, with parts being shown in section;

Fig. 2 is a section taken on line 22 of Fig. 1;

Fig. 3 is an enlarged section taken on line 33 of Fig. 1;

Fig. 4 is a section taken on line 4-4 of Fig. 1; and

Fig. 5 is an enlarged section taken on line 5-5 of Fig. 1.

Referring now to the drawings, our comb is designated generally by the numeral 5, and comprises a head 6 and a handle portion 1.

The head 6 comprises a base I5 having teeth l6 cast integral therewith. It is our preference to cast the head of any suitable electrically insulative plastic material, such as an acrylic, or Bakelite, having sufficient stiffness to render it usable as a comb.

An electrically conductive wire H has one of its ends connected to a terminal l8 and its other end disposed for conductive connection with an electrically conductive resilient strip iii to be more specifically described hereinafter. The wire I! leads from terminal l6 along the base, thence downwardly along the forward edge of the outerendmost tooth l6, thence upwardly within said tooth, and thence continues in like manner through each successive tooth, finally extending back through the base, ending in contact with a ring 20, the ring being disposed to contact strip 19.

As best seen from Fig. 5, the wire l'l fits in a semicircular, longitudinal slot 22 in the forward edge of each tooth, so that the wire is thus exposed to contact with the hair as the combing operation is performed.

While various means may be provided for supplying electric current to the wire, we shall now describe the means which we at present prefer, being a conventional dry cell housed within the hollow handle 1.

The terminal 3| at the left end of the cell is disposed to contact terminal l8, while the opposite end terminal 32 of the cell is conductively connected to the flanged inner end I911 of the strip l9 by means of a coil spring 34.

The strip [9 is in two sections whose contiguous ends 19b, are spaced apart, and the gap between those ends is adapted to be bridged, for the purpose of closing the circuit, by a slide switch 35 which has a manually engageable portion 35a projecting through and movable along a slot 36 in the handle.

So that the handle may be removed for changing the dry cell, it has a threaded end portion 38 engaging external threads on the inner end of the base.

In operation, the device has its circuit closed by manually sliding the switch 35 to the left, thus causing the electrical circuit to set up a magnetic field about the teeth, and particularly along the forward edge of each tooth, the wire being directly exposed to contact with the hair along said edge of each tooth.

It will be understood, of course, that although the construction just described in detail is the one which we at present prefer, our invention is susceptible of being carried out in other and modified specific physical forms without departing from the broader scope of the invention as now to be defined in the claim.

We claim:

An electrical comb comprising a base having comb teeth of electrically insulative material formed integral therewith, each of said teeth having a longitudinal groove in one of its edges opening towards the next contiguous tooth, an electrical switch carried by said base, an electrically conductive wire connected at one end to one terminal of said switch and thence leading downwardly along and imbedded within each of said respective teeth, thence upwardly in exposed position along said groove therein and thence being connected at its other end to the other terminal of said switch, and means for electrically energizing said wire through said switch.
