14 Claims.

This invention relates to improvements in hair waving apparatus of the kind used in beauty parlors for the commercial waving of human hair.

An object of my invention is to provide im-- proved hair waving apparatus embodying a construction capable of being readily manipulated by an operator and which can be conveniently controlled to secure a desired Waving effect.

Another object of my invention is to provide improved hair waving apparatus embodying a novel and compact structure which permits the convenient use of a large number of hair waving heaters at one and the same time. I

A further object of my invention is to provide 1 improved hair waving apparatus of the kind em- 15 ploying a number of hair waving heaters, which embodies yieldable means engaging with the electric cords connected to the heaters, the said means being adapted to releasably support a number of the cords in independently adjustable positions.

Other and further objects of the present invention will be pointed out hereinafter, indicated in the appended claims, or obvious to one skilled in the art upon an understanding of the present disclosure. For the purposes of this application I have elected to show herein certain forms and details of hair waving apparatus representative of my invention; it is understood, however, that these are presented here for purposes of illustration only, and that therefore they are not to be regarded as exhaustive of the variations of the invention, nor are they to be given any interpretation such as might have the effect of limiting the claims, short of the true and most comprehensive scope of the invention in the art.

In the accompanying drawings:-

Fig. 1 is' a side elevation of hair waving apparatus embodying my invention;

Fig. 2 is a top plan of that part of the apparatus which supports the terminals, the electrical cords and other parts of the hair waving equipment;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 4, showing a part of the insulating material in which the connected electrical terminals are imbedded, broken away;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3;

55 ignates' a suitably shaped base having secured Fig. 5 is an enlarged sectional view taken on thereto an upstanding tubular post 2 which adjustably supports a standard 3. Secured to the upper end of the standard, as by a set screw 4, is

a horizontally disposed hollow arm 5 which has an opening on its underneath side near its free 5 end through which electric cords are adapted to extend.

Journaled to the free end of the hollow arm 5 is a crown-shaped supporting structure 6 which is provided at its lower end with an outwardly and upwardly disposed annular flange 1. Overlying and supported by the annular flange 1 is a ring-shaped plug board 8 made from bakelite or other suitable insulating material. The plug board 8 maybe rigidly secured to the flange l by any suitable means, such as by screws 9 extending into threaded bosses 10 provided on the upper side of the said flange.

Entirely imbedded within the insulating material. from which the ring-shaped plug board is made, are five semi-circular and concentrically arranged bars or strips H, I2, l3, l4 and [5 made from copper or other suitable material capable of conducting electrical currents. The inner semi-circular bar E i is connected to the negative side of an electrical circuit and the bar I3 is connected to the positive side of the said circuit. The intermediate bar i2is grounded. Also connected in this circuit is a switch Iii and an electric light globe ll. Arranged in groups of three and electrically connected to the bars H, H and i3 are terminals 58 which are preferably tubular in shape and of a size capable of receiving the metal contact members of electric plugs it. Each of the bars and their respective terminals i8 are preferably formed integrally with one another as a solid unit, as by casting, thereby eliminating all mechanical or soldered connections. At points where the terminals I8 occur the plug board 8 is provided with holes for the insertion of the metal contact members of the plugs i9, the said contact members of each plug being three in number, the center one being the ground connection.

. The outer semi-circular bar I5 is connected to the negative side of another electrical circuit and the bar it is connected to the positive side of said circuit. The intermediate bar I4 is grounded. Also connected in this circuit is an electric light globe and a switch 2|. The bars l5, I4 and i3 are also provided with terminals 18 which are similarly arranged in groups of three. Both of the circuits are supplied with an electrical current by wires 22 leading to a source of electrical power, and a time switch 23 connected in the circuit leading to the source of power provides for the manual closing of the supply circuit and the automatic opening thereof at the duration of a predetermined period of time.

The globes H and 20 are suspended from sockets mounted on a bracket 24 secured to and extending diametrically across the crown-shaped supporting structure 6. The globes extend through a concave disc 25 which is held in a closed position against the lower end of the structure t by the said globes. The wires 22 supplying the apparatus with electrical energy extend through the hollow arm and the opening at the free: end of the latter, and downwardly through the crown-shaped supporting structure 6.

The various groups of terminals l8 provide electrical outlets for plugs l9 which are con nected to hair waving heaters 26 by cords 21. So as to hold the heaters 26 in suspended positions and at the same time permit the vertical adjustment thereof, I have provided a number of outwardly disposed supporting structures which are adapted to frictionally but yieldably engage with the cords 21. The outwardly disposed supporting structures for the cords 2'5 each comprises an outwardly disposed bar 28 secured at its inwardly disposed end, as by a screw, to a boss on the flange 7. Each bar 28 extends through a slot provided in the upturned periphery of the flange i. Slidably, but not rotatably, mounted on the bar28 are a plurality of pairs of clamp members 29 having curved or arcuate end portions between which a cord Ell is adjustably held. Encircling the bar 28 and interposed between cer tain of the clamp members 29 are spiral springs 30, the function of which is to yieldably maintain the clamp members of each pair in gripping engagement. The springs 3E? exert sufficient pressure upon the clamp members 29 to normally hold the engaged cords 2'! in positions wherein the heaters 26 are supported at desired levels. The vertical position of any of the heaters 26 may be conveniently adjusted by pulling its associated cord either upwardly or downwardly with sufficient force to overcome the gripping engagement of the contacting clamp members. The number of heaters employed in a hair waving operation, may of course, be varied to suit different requirements.

It is apparent that my invention may be embodied in apparatus wherein a single circuit is employed, or again in apparatus where a considerable number of circuits are required. In

each instance the various conductors and terminals may be imbedded in a suitable insulating material in the manner herein shown and described. It is also evident to those skilled in the art that the principle of my invention, insofar as it concerns the apparatus for supplying an elec-- trical current to a large number of outlets, may be satisfactorily employed in connection with different kinds of constructions other than hair waving equipment. In this regard it is to be understood that the scope of my invention is to be determined by the appended claims rather than by the exact disclosures herein made.

Preferably, in making a plug board in accordance with my invention the various bars or strips and their connected terminals are first arranged in predetermined positions within a suitably shaped and constructed mould. Molten or liquid insulating material such as bakelite, sufiicient to fill the mould is forced with considerable pressure entirely around and into firm contact with the bars and terminals. The mould is preferably provided with suitably shaped protuberances or independently removable pins which extend to points where the terminals l8 occur, and which, when withdrawn from the hardened insulating material forming the body of the plug board, leave suitable openings for the insertion of the contact members of electrical plugs. The terminals may be provided with central openings for the insertion of the contact members of the plugs by any suitable means, such as by drilling holes therein.
