ELECTRICALLY-HLATED CURIIING IRON.

Application filed my 31,

This invention relates to improvements in electrically heated curling irons, and has as its primary object the provision ofa novel curling iron in which the body and the conductorcords' swivel relative to each other;

An important object of the invention resides in the provision of new and improved means for swiveling the cords and the heat? ing element as a unit in the body of the curling iron.

Other objects reside in the provision in a curling iron of the above character of means for relieving strain on the electrical connections in the body of the iron, and means for protecting the cords at the outer end of the handle.

A general object of the invention is to provide a novel curling iron of the above character which utilizes standard features of construction of irons in which the cords are fixed, and which is simple and inexpensive in construction.

Further objects and advantages will become apparent as the description proceeds.

In the accompanying drawings:

Figure 1 is a longitudinal section of a curling iron embodying the features ofmy invention.

Fig. 2 is a fragmentary longitudinal section of the curling iron taken along line 22 of Fig. 1;

.While the invention is susceptible of various modifications and alternative constructions, 1 have shown in the drawings and will herein describe in detail the preferred embodiment, but it is to be understood that I do 'not thereby intend to limit the invention to the specific form disclosed, but intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claim.

Referring more specifically to the drawings, the exemplary embodiment of the invention comprises a suitable handle 5 and a suitable shank 6 inserted at one end in one end of the handle. The shank 6 is of tubularform suitable for holding an electric heating elementv 7, and the handle 5 is formed with an axial bore 8 for the electric leads -to the heating element. Pivotally mounted on the shank 6 is a suitable crimper 9 having an operating arm 10 adapted to be depressed by finger pressure to pivot the 1927. Serial no. 195,188.

crimper away from the'shank. A suitable spring 11 is inter-posed between the shank. 6

and the arm .10, and tends to pivot the crimper 9 toward the shank.

The heating element 7 may be of any suitable type suitably insulated, andis loosely disposed in the shank 6. A pair of insulated lead wires 12 are electrically con- .nected to the heating element 7 at 13, and

extend therefrom through the shank 6 into the bore 8 of the handle 5. Electrically connected to the lead Wires 12 at 14 in the here 8 are two electric cords 15 which are taped together at 16 and which extend out of the handle 6 for connection to a suitable source of electric current. V

Means is provided for permitting the body of the curling iron to be rotated or swiveled relative to the cords 15 so as to prevent twisting of the cords when hair is wound end of the bore 8 is enlarged at 17 thereby providing an annularshoulder 18. Rotat ably seated against the shoulder 18 is a bearing washer 19'which preferably is made of insulating material, and which has a central heating element 7 .the wires 12 and the cords against longitudinal displacement in the curling iron relative to the washer 19. Removably secured in the outer end of the enlargement 17 of the bore 8 by means of a set screw 24 threaded laterally into the enlargement is a plug 25 which preferably is made of insulating material, and which abuts against the washer 19 to hold the latter against the shoulder 18, and thereby to hold the heating element 7 rotatably in position in the shank .6. The plug 25is formed with an axial bore 26 for the cords 15.

-To protect the cords 15 against injury from excessive bending, a coiled wire 27 is disposed thereabout at the point where they leave the handle 5. The 'coil of wire 27 extends through the bore 26, and the inner end thereof abuts against the washer 19.

75 around the shank 6. To this end, the outer cords 15 in the handle 5.

To hold the wire-27 against displacement,

the inner end of the bore 26 is flared as shown at 28, and the inner end of the coil is enlarged as'shown at 29.

It will be evident that-I have provided a useful and advantageous curling iron of which the body can be rotated without twisting the electric cords. The heating element 7, the lead wires 12 and the cords 15 are rotatable as a rnit within the body. The Washer 19 provides a, simple and eflicient bearing means for holding the parts in place. The construction is advantageous in that it provides strain relicf for the electrical connections at 13 and 14, thereby preventing injury to the latter through rotation of the The invention utilizes standard construction, and in general the construction is simple and inexpensive.

I claim as my invention:

A curlingviron having, in combination, a

handle having an axial bore, said bore being formed with a bearing surface, a hollow metal shank secured to said, handle,

.a heating element in said shank, a plug having an axial bore in the outer end of said first mentioned bore, electrical cords extending through said bores and connected to said heating element, a narrow bearing Washer encircling said cords and rotatably disposed between said bearing surface and said plug. the opening of said Washer being flared, a plate having a taper end wedged into said flared opening and having notches embracing said cords to hold the latter against slipping, and a coiled wire encircling said cords. in said plug. said last mentioned bore and said Wire coil being flared to retain said wire in position.

In testimony whereof, I have hereunto aifixed my signature.

EUGENE MEEK.
