Q? 02% mar/75y Patented Oct. 21, 1930 G. SHEL'ION, OF ST. LOUIS, MISSOURI LHAIR-WAVING DEVICE Applicatioafiled January 21, 1929. Serial No. 333,895.

My invention relates to the art of permanent curling or waving of the human hair and consists in a novel apparatus for applyingv heatto the curled strand of hair and the supply wra ped about the same.

One. of the 0 ects of my invention is to provide means or applying the heater to the strand of hair at as close a point to the scalp of the user as possible. It is necessary, in the use of heaters of this type, to protect the scalp of the user from burns or scalding due to the heater or steam or hot fluid escaping from the supply or curl which have moisture applied thereto during the curling operation and it is a further object of my invention to provide an effective seal for this urpose. I

It is customary to apply a clamp to the strand of hair adjacent to the scalp and to mount the heater on this clamp. The clamp has heretofore included strips or slabs of 'cork, rubber or similar yielding insulating material, the effectiveness of which was limited because the clamping of a strand of hair between the opposed edges of the slabs would result in indentations bein formed in these edges which indentations, 1n later applications of the clamp, would form passageways for the seepage of steam. and hot fluid to the seal of the user. In such clamps as I am familiar with, the yielding clamp elements have been of such thickness that the curling rod and heater could not only be positioned as close to the scalp as desired ut alsothe clamp and heater could not be held in as stable a position as desired.

Anotherobject of my invention is to rem- .ed this unsatisfactory (condition.

t is a further objectfof my invention to provide hair-engaging strips for the clamp which shall be easily renewable and will form an effective seal between the scalp of the user and the heater.

These and other detailed objectsof my invention are attained by the use of the structure illustrated in the accompanying drawings in" which Fi ure 1 1s aperspective view of the heater mem er. y

-5 Figure 2 is, a transverse. vertical section through the same showing it applied to a strand of hair. .Figure 3 is a perspective of the clamp on which the heater is mounted.

' Figure 4 is a pers ective of the outer portion or envelope 0 the renewable strip for the clamp. j a

Figures 5 and.6 are perspectives of fillers for the envelope shown in Figure 4.

Figure 7 illustrates the manner of assembling the strips with the envelope.

The heater member has an arcuate body 1 containing an electric resistance heating element and mounting a block 2 of insulating material on its convex surface. Spring clips 3 are attachedto each'side of the block 2 and each cli comprises an end portion secured; to the b ockby'a rivet 4, or other suitable means, and an offset intermediate ortion and an outer portion 5 spaced from lock2.

Separately formed arms 6 are mounted upon the outer portions 5 of the spring clips and project upwardly and downwardly therefrom. The upwardly projecting portions form handles 7 for manipulating the 7 heater and the downwardly projecting portions 8 terminate in jaws 9 extending under the lower edges of the heater 1 and adapted to project to grip the strand of hair S and the supply P. It will be understood that the spring clips 3 hold or tend to hold the jaws in the full line osition shown in Figure 2 but the compression of the handles 7 towards each other will move the jaws 9 away from each other so as to permit application or removal of the heater member to and from the cylinder-like body formed by the strand of hair wrapped about the rod 10 and enclosed in the supply-P. I

By mounting the arms 6 as shown. the structure is simplified as compared with devices including hinges and spring devices for closing the jaws on their hinges, and this arrangement also forms a pivotal mounting for the arms 6 spaced substantially from the center o'f the heater and farther apart than the faces-of the jaws so that movement of the jaws into and out of their grippin position '1s accompanied by a "minimum 0 vertical movementfthereby permitting the device to be applied to the strand of hair nearer to the scalp than in devices where the arms are pivoted on the center line of the heater.

The heater and curling rod are mounted upon the clamp device comprising a pa r of bars 11 pivoted together at one end as 1nd1- cated at 12 and provided with a releasable latch 13 at their other end. The pivoted end of the bars is provided with an upstand ng lug 14 having a slot 15 adapted to receive a squared pin 16 extending from one end of the curling rod 10. The latch 13 is provided with an upstanding lug 17 adapted to engage a similar pin formed on the other end of the curling rod.

Each of the bars 11 is preferably formed of .channel section as best shown in Figure 2 and these bars are open at their ends.

A sealing and insulating member 18 is pro vided for each clamp bar and consists of a loop oftubular material applied to the lower flange of the bar and this loop is preferably formed of tubular elastic material and is closed. A tube formed of rubber of substantial thickness may be used for this purpose and may be stretched lengthwise to fit over the bar flange, the tube being wide enough to project from the edge of the flange a substantial distance so that, when the bars are clamped together, the upper leg of the loop will be compressed along the strand of hair to form a tight joint. The lower leg of the loop has some play relative to the bar and provides a more comfortable support for the clamp and heater and also contributes to the insulation of the heater from the scalp A.

In the preferred embodiment of my invention. the tubular loop 18 is provided with inserts 19 and 20 of flat and comparatively rigid material, such as bakelite or vulcanized rubber. By slitting one end of the loop '18, as indicated at 21. the fillers 19 and 20 may be inserted in the upper and lower legs of the loop. By twisting the loop inside out, so tospeak, the slit 21 may be turned inwardly so that it is not visible, thereby adding to the appearance of the product. Figure 7 illustrates the tube asit is being turned from the position with-the slit 21 outwardly to a position with the slit inwardly.

The loop 18 may be formed of a tube with ends abutting each other and this will simplify the manufacture and eliminate the slit.

I show the lower filler 20 as being provided with a lateral offset 22 and this feature will provide a wider base for the clamp, thereby increasing its stability and reducing the tendency of the apparatus to turn from its vertical position and making it more comfortable for the user. This feature will also provide I finger holds spaced from the metal ofbars 11 whereby the operator may pick upthe clamp when the bars are hot. i

The described structure provides a omt which is tight against water and steam member. The quadruple layer of rubber between the scalp of the user and the, heater member and the relatively small proportion of metal provided by the bars 11 adequately insula e the scalp of the user from the heat generated in the heater.

The described structure is adapted for Variations in the type of equipment with which it is used as the rubber loops may be stretched over different lengths of bars and may have fillers of different widths and thicknesses inserted therein. For example. the upper fillers 19 may be of increased thickness to provide a greater area of contact with the strand of air.

It is obvious that the details of the structure may be varied substantially without departing from the spirit of my invention and I contemplate the exclusive use of such modifications in the device as come within the clamp comprising a pair of rigid bars pivoted to each other near one end and an.in-

dividual endless tube of compressible material cletachably applied around each of said bars so as to contact with a strand of hair between said bars and to space said bars from the scalp of the user, and means within said tube giving it a flattened shape for.
