ELECTRICAL I-IAIR-CUBLING APPARATUS.

Application filed June 18, 1925.

My invention relates to electrical hair curling apparatus, my more particular purpose being to provide a device of this character having certain specific advantages hereinafter set forth.

More particularly stated I seek to produce an electrical hair curling apparatus in which I employ a number of separate heating units, connected preferably in parallel with each other relatively to the source of electrical supply.

By use of my improved ap iaratus, connected as hereinafter described, I attain a considerable number of specific advantages, among which are the following:

First. It is rendered practicable to con struct and operate a large number of heating units all of them heating uniformly under all practicable working conditions.

Second. That it is practi able to vary within wide limits the number of heating units actually employed from time to time, changes in the number of units having relatively little effect upon the action of the several individual units actually in operation.

"hird. That by means of my improved apparatus the dangers of arcing and sparking, due to electrical short circuiting or to poor coimections, are avoided or at least reduced to a minimum.

Fourth. That owing to the construction and operation of the apparatus. the danger of a shock to the person whose hair is to be treated is greatly reduced, or prevented altogether.

Reference is made to the accompanying drawing forming a part of this specification, and in which the figure a side view, partly sectional and partly diagran'imatic, illustrating my improved electrical hair curling apparatus and indicating the manner in which it is used.

Mounted upona wall 7 are brackets S sup porting a conduit tube 9, the latter carrying a distributing head 10 having the proximate form of a bell, as indicated in Figure 'l.

A step down transformer is shown at 11. and in this instance is a transformer of the so-called shell type. However, any other appropriate form of step down transformer may be used, if of .suliicient capacity to supply an adequate amount of current for each and all of the heating units as hereinafter described. In practice by making the trans- S'crial No. 37,921.

former rather large it is an easy matter to render the secondary voltage substantially constant independently of the number of heating units energized from time to time while the transformer is in active use.

The transformer 11 is energized by aid of a pair of primary conductors 12, 13, con trollable by a switch 14.

Connected with the transformer 11- are a pair of secondary conductors 15, 16. Connected with the conductor 16 are a number of small hand switches 1'7, 18, 19. lVhile only twelve of these switches here shown the number may readily be larger, say from fifteen to eighteen.

Connected with these switches 17, 18. 19, are conductors 20, 21, 22 which may be in the form of either wires or conducting cords.

The bell 10 carries a ring 23 of metal or other conducting material, and also carries a ring 24: of insulating material whereby the ring 23 is insulated. The ring 23 is connected with the secondary conductor v15 above mentioned and is provided with a number of binding posts 25 to facilitate making electrical connections.

A number of sectors 26, 27, 28, each made of metal or other conducting material, are arranged in the form of a circle and separated by spacing sectors 29 of insulating ma terial. Any number of these sectors 26, 27, 28, may be employed, the number being the same as that of the wires 20, 21, 22. The sectors 26, 27, 28, are each provided with a binding post 29, there being as many of these binding posts as there are of the binding posts 25. It will be noted that while each binding post, together with the sector such as 26, 27, 28, upon which it is mounted, is energized by some one of the conductors 20, 21, 22, whereas all of the binding posts 25, together with the single ring 23, upon which they are all mounted, are energized by means of the single conductor 15.

I provide a number of double conducting cords 30, 31, 32, for conveying current to the heaters, there being as many of these double cords and many heaters as there are individual conductors 20, 21, 22.

Each double cord 30, 31, 32, is provided with. two branches 30, 30 leading to a pair of binding posts 25, 29, above described.

I do not limit myself to the precise mechanism here shown, as variations may be 4 I 1,ee7,72e
