v 1 claim. (c1. 12er-,355)
This invention relates to new and useful improvenients in hair removing instruments, especially tweezers for pulling hair from the human body. 4
More specifically, the present invention proposes the construction of a tweezer device including a pair of tweezer members embedded in a body of insulating material and connected to an electric circuit adapted, when charged, to send current through the members to the hole made by pulling a hair todestroy the hair reproductive ability of the cells at the hole. x
Still further, it is proposed to provide a device as aforesaid including resistances and a neon tube for reducing the current to an amount which will effect the desired result without shocking the human body, the human body being part of the circuit.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawingsand to the appended claim in which the various novel features of the invention are more particularly set forth. i
In the accompanying drawings forming a material part of this disclosure- Fig. 1 is a foreshortened perspective view `of a tweezer device constructed in accordance with this invention.
' Fig. 2 is an enlarged section on the line 2-2 of Fig. 1.
Fig. 3 is an enlarged longitudinalcentral sec-' tional view of the device.
Fig. 4 is a diagrammatic view of the device showing the circuit thereof.
Fig. 5 is a similar view to Fig. 1, but illustrating a further modification of the invention.
The electrical hair removing instrument according to the present invention, comprises a casing I of plastic, hard rubber or other suitable non-metallic material, open at its end II and closed at its opposite end by a wall I2 providedv with an orifice I3. The casing is hollow and has an internal shoulder I4, providing a chamber I .between the shoulder I4 and the wall I2. Opposed openings I6 in the side of the casing provide vision into the chamber I5.
A soft rubber tube I1, or other insulating material is disposed in the casing outwardly of chamber I5, the inner end of the tube Il abutting the shoulder I4 and the outer end protruding a considerable distance beyond the end II of the casing, the protruding outer end forming an extension I8. Tube Il is large enough to form a tight squeezing t in the casing, which fit prevents the 2 tube I1 from becomingV disassembled from the casing.
The tube I'Iihas ,various members embedded in it, insulating these members and supporting them. If desired,` these members could be individually insulated andthen disposed in suitable orifices in the tube I'I.
In `the innerlend of the tube Il is a socket IS in which is screwed a neon or other tube 28 or other suitable indicator which is visible through the openings I6. In the outer end of the tube Il are secured two tweezer members 2I, these members 2l extending about 1/2"V to 1%. beyond the outer end of the tube I1. These members 2| are similar in shape to conventional hair pulling tweezers, such asr'tweezers adapted to be used for pulling eye-brows, eye-lashes and other small hairs. t
A contact plate 22 is embedded in extension IB with its exterior surface protruding beyond the tube Il and therefore being exposed. This plate 22 may be made of any suitable metal such as copper. "p "f An electric circuit is provided for the tweezer device for a purpose presently to appear. It includes a plug 23 `adapted to beinserted in a conventional wall socket in a house for obtaining a supply of electric current (direct or alternating). The plug 23 has two points 24 for a double wire 25 having two leads 26 and 2l'. .This wire 25 passes through orifice I3 and lead 2B is connected with the socket I9 for the neon tube. Y Lead 21 is connected to a resistor 28 which is electrically connected with plate 22. The two tweezer members 2l are electrically connected by a wire 29 which is connected through a resistor 30 to the socket Iii and neon tube.
The operation of the device is as follows:
The tweezer can be used to pull any hair from a body, especially a small hair from a human body, such as mustache or Whisker hairs on a ladys face. The person grips the device with the thumb on the plate 22 and the index finger on the extension I8 near the outer end thereof. The membersY 2| are then placed on opposite sides of the hair to be pulled. If the skin is touched, no harm will be done. The person then squeezes the extension I8, which is of rubber, thus moving the members 2| together into gripping contact with the hair. The hair is then removed by a short sharp pull. Rubber extension I8 is sufliciently soft to enable a lady to easily move members 2l together. The construction of the tweezer members 2|, acts as a spring, when the squeeze is released, forcing the Amembers 2l apart.
As soon as the hair has been pulled out, the tweezers are touched to the skin at the point from which hair was removed. This contact completes the electric circuit through the lead 26 to the neon tube, therefrom through the resistor 30 to the tweezer members, therefrom through the body of the person to the plate 22 and then through the resistor 28 to the lead 21. The current supplied through the tweezer members, due to the resistors and neon tube, will be very low and will not cause a shock, but will supply enough current to treat the cells at the spot from which hair was removed to inhibit a reproduction of another hair.
The soft rubber tube l'l serves the double purpose of insulating the tweezer members 2l from the persons hand, and supporting plate `22. The neon tube serves as an indicator of contact and current flow, and limits the amount of current sent to the resistor 30. The electric current may be applied directly, through resistance, inductance or capacity, or through a combination of them, as desired. The cell treatment by the electric current at the spot from which hair Was removed destroys, kills or renders dormant the hair root preventing or inhibiting the regrowth of the hair.
The aforedescribed electric tweezer device enables an individual to remove hair in the privacy of his or her home in an economical and easy manner. The device is very simple to use, there is Ano danger of shocks or injury to the skin, the current flowing through the body is measured in microamperes, and Vthe device is inherently capable of long life and easy repair.
In Fig. 5, the device is shown 'to be provided with an extension member 32. This extension member consists of an insulated wire 33,-connected to the plate 22 at one end, which is covered with suitable insulation, and a hand terminal 33 is connected at the other end. This hand terminal 33 may be held or placed in contact with the person Who receives treatment by another person, in the event the device is not used for self treatment. f
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claim.
Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
An electric tweezer device for pulling da hair and treating the hole electrically to inhibit hair regrowth comprising a. casing, a soft rubber tube in said casing having an extension exteriorly of said casing, a metal plate secured to said extension and being exposed exteriorly, a pair of tWeeZer members secured to said rubber tube and extending therebeyond adapted to be moved together for pulling a hair by squeezing said extension, said casing extending beyond the end of said rubber tube remote from said tweezer members providing a chamber, a neon tube in said chamber supported by said rubber tube, an electric wire lead for transmitting current between a source of electricity and said tube, another electric wire lead for transmitting current between said tube and said tweezer members,A another electric wire lead for transmitting current between said plate and to said source whereby when said tweezer members are brought into contact with said hair hole in a human bodyV and said plate is brought into contact with said human body, said human body closes the circuit, lights said neon tube and effects current passage from said tweezer members to said hole, treating the cells at said hole and said hair root to inhibit hair regrowth.
