HAIR REMOVING APPARATUS Application filed September 3, 1931.
This invention relates to hair removing apparatus and more particularly is directed tc a multiple needle electrolysis type depilator, such as used for removing visible or undesirable hair from different parts of human bodies.
Among the objects of this invention is to generally improve depilatory apparatus of the character described whereby the latter shall comprise few and simple parts which are easy to manipulate and convenient to apply, which shall form a neat and compact structure, which shall be cheap to manufacture, and practical and efficient to a high degree in use.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the constructions hereinafter described and of which the scope of application will be indicated in the following claim.
In the accompanying drawing, in which is shown various possible illustrative embodiments of this invention:
Fig. 1 is a perspective view showing a portable type of electrolysis depilator constructed to embody the invention, and set up ready for use.
Fig. 2 is a cross-sectional view taken on lines 22 in Fig. 1.
Fig. 3 is a diagrammatic view showing the electrical circuit incorporated in the improved depilator, and
Fig. 4 is a front elevational fragmentary View, partly in sections, showing a foldably collapsible form of arm and rack construction embodying the invention.
Referring in detail to the drawing, 10 denotes portable type of electric depilator apparatus constructed to embody the invention. Said apparatus 10 is seen to comprise a suitable box 11 preferably of light weight, durable construction having a bottom and top hinged covers 13 and 12, respectively, and a base plate 14 which forms an upper side of the box 11 under the top cover 13. Said base Serial No. 560,921.
plate 14 may be retained in position by any suitable means such as screws 15.
Carried on the base plate 14 are the parts of the apparatus 10, such as a rheostat, dial, and knob indicated generally at 16, a switch 17, a meter 18, terminal post 19, and metallic stand or support 20. All the aforementioned parts are connected in electric circuit with a suitable power source, as for example, dry cell batteries 21, as shown in Figs. 1 and 3. The batteries 21 are housed in the box 11, and can be inspected or replaced by simply loosening latch fittings 22 and swinging the bottom cover 13 open in the well understood manner.
The stand or support 20 connects with the 6 lower end 23a of a metallic arm 23. Said end 2364 preferably forms part of a suitable swingably adjustable connection 24 secured by a clamping screw 25. The upper end 237) of said arm supports a rack 26 through another swingably adjustable connection 27 having a clamping screw 28.
The rack 26 may comprise a metallic center rod 29 which extends from the connection 27. Said rod has fixedly secured thereto spaced insulating strips 30 and 31. The strip 30 positioned adjacent the connector 27 is faced with a metallic plate 32 which is provided with uniformly spaced through openings 32a. Said plate 32 and opening 32a form terminal junctions for connecting flexible conductor wires 34 with the stand 20, arms 23 and rod 29, in the manner hereinafter described. 85
The strip 31 is positioned to terminate the rod 29 and may be provided with uniformly spaced openings 31a which has angularly extending slots or passages 31?).
Inserted firmly into each of the plate open ings 32a which forms a receptacle, is the end plug terminal 33 of the flexible conductor wire 34, the other end of said wire carries a socket 35, into which a needle 36 is fitted in the well understood manner. The conductor wires 34 extend through the strip openings 31a and may be readily slipped in and out thereof through the slots 31?).
When the needles 36 are not in use the conductor wires 34 may be drawn back and laid in the spaced slots 30?) so that the needles 36 hang in a position not to interfere with the hair removing operation. The angular position of the slots 316 do not allow the conductor wires to be accidentally displaced from the opening 31a as is clear from Fig. 1.
A suitable metallic cup 40 or sponge (not shown) for retaining a conducting liquid, such as a salt water solution, in which fingers or other portion of the patients body is immersed is provided. Said cup 10 may be formed with a terminal post 41, which is interconnected through a suitable conductor wire 4-2 with the terminal post 19 on the base plate 14.
The use of the improved apparatus 10 will now be apparent. After the parts have been assembled, and positioned as shown in Fig. 1 with the circuit parts arranged as shown in Fig. 3, any one of the needles 36 is inserted into the skin to contact with or pierce the root of a hair to be removed, the fingers of patient being immersed in the liquid in the cup 40 and the switch 17 closed to complete the circuit. The knob of the rheostat 16 is next turned until the desired current is permitted to flow, as indicated on the ammeter 18. The hair is then electrolyzed without burning or otherwise injuring the skin or flesh. A plurality of needles may be used simultaneously to shorten the treatment, the current being regulated correspondingly.
By arranging the parts as shown in Fig. 1 and described above, the base plate is left clear and permits forming a more attractive appearing apparatus which is convenient to operate. The conductor wires 3% and needles 36 not in use may be drawn back so as not to interfere with the operator or inconvenience the patient.
The entire apparatus 10 as shown in Fig. '1 is enclosed in the box 11 and may have the cover 13 secured to prevent unauthorized use by a suitable lock 37. IVhen said apparatus is not in use, the arm 23 is dismounted and stored in the top cover 12, being retained by the companionate spring clips 38. The rack 26 is also disconnected from the arm 23 and retained by the companionate spring clips 39, as shown in dot-ted lines in Fig. 1.
To eliminate the necessity of dismounting and disconnecting the arm 23 and rack 26 from the apparatus as described above, a modified form of the invention is shown in Fig. 4. Here the rack 26 is provided with an upper connection or goose-neck structure 127 which allows the rack to be folded against the arm 23. The stand or support 20 is positioned adjacent one end of the base plate 1 L so that the arm and rack may be folded down against the plate 14 under the cover 12 as shown in dotted lines in Fig. 4. The upper connection 127 has a clamping screw 128 and may be coupled to the arm 23 by means of slot and pin joint 127 a to permit limited swinging movement of the rack 26 with respect to the arm 23.
It will thus be seen that there is provided an apparatus whereby the several objects of this invention are achieved and which are well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
In combination with a box provided with a cover, a base mounted on said box, a metallic arm supported on said base, a battery mounted in said box, means connecting withsaid battery in conductive relation with said metallic arm, a first rack swingably supported on said arm and having a plurality of plug openings formed therein adapted to receive electric terminals, said first rack being in electrically conductive relation with said metallic arm, a second rack supported by said arm and positioned in spaced relation to the first rack and having a plurality of oblique slots formed therein adapted to support conductor wires.
In testimony whereof I afliX my signature.
