y 8, 1934- G. DECKER APPARATUS FOR HAIR WAVING Filed Oct. 14, 1929 @0 6 fieozl'l By fiii hu-:1 smg Patented May 8, 1934 UNITED STATES PATENT OFFICE APPARATUS FOR HAIR WAVING George Decker, Cleveland, Ohio, assignor to The Philad Company, Cleveland, Ohio, a corporation of Ohio This invention relates to apparatus for waving hair upon the human head and more particularly to the hair winding and heating apparatus adapted for use in the permanent process of waving.

An object of the invention is to provide an improved heater which may be simply applied to a coiled strand of hair.

Another object is to provide an improved heater which may be readily and economically manufactured.

Other objects will hereinafter appear.

The invention will be better understood from I the description of several practical embodiments illustrated in the accompanying drawing, in which;

Figure 1 is a perspective view of a heater applied to a curler rod and a protector clamp, as

I used in one process of permanent waving;

Figure 2 is a perspective view of the retaining means of Figure 1;

Figures 3 and 4 are views similar to Figure 2 of modified forms of the retaining means; and

Figure 5 is a transverse sectional view of the apparatus illustrated in Figure 1.

In one process of permanent waving, the hair of the subject is divided into flat strands, and each strand gripped adjacent the scalp of the wearer by a protector or clamp. The strand is then wound from its ends spirally, one turn over another, upon a curler rod which rests upon the upper surface of the protector, parallel to the surface of the head, and the wound strand, treated with a suitable solution, is subjected to heat to cause the hair to become set or waved.

In Figure 1, a protector clamp is shown as consisting of two arms 1 and 2 which are arranged to be clamped in parallel relation to grip a strand of hair. A curler rod 3 consisting of a tubular body having a reduced intermediate section is provided for the winding of the hair. One end of the curler rod is provided with slots 4 which may be selectively engaged by a detent formed on a spring 5 attached to one arm of the protector, and

so constitutes a pawl and ratchet to prevent the rotation of the rod in a direction to permit the hair to unwind. These parts may be substantially as described in any one of my copending applications, Serial Numbers 347,324, 368,544 or 379,187.

After the hair has been wound upon the rod and the latter engaged by the pawl of spring 5, the wound strand may be covered with a suitable pad or the like containing, if desired, a solution I for treatment of hair, and the wound and covered strand is surrounded by a heater by which the heat for effecting the wave is produced. The heater illustrated consists of an arcuate hollow shell 6 within which is a heating element consisting of a coil of resistance wire insulated by sheets of mica or the like, to which coil current is supplied through conductors 7 passing through an insulating handle 8 secured to the shell by screws 9.

To retain the heater in place about the strand of hair, a strip of spring metal 10 is provided, this strip consisting of a widened central portion 11 having perforations 12 through which the securing screws may pass and perforations 13 for the passage of the lead-in wires.

The ends of the strip are bent downwardly as at 14 and adjacent their ends have inwardly extending bends 15 adapted to spring into the open end spaces of the curler rod, as shown in Figure 1, so that the heater may be simply applied by pressing it down over the wound strand of hair until these projections snap over the ends of rod 3. The heater is thus resiliently held to the rod, from which it may be simply removed by pulling it upwardly, so that projections 15 will spring over the ends of the curler rod.

In Figure 3 a modified spring strip 110 is shown in which a central portion 111 is provided with perforations 112 and 113, the downwardly extending ends 114 having a somewhat corrugated shape to provide a series of inwardly extending projections 115, any one of which may be caused to spring over the ends of the curler rod, so that the heighth of the heater shell above the protector clamp may be adjusted by the operator to suit the size of strand of hair wound upon the rod.

In Figure 4 a still further modification of the spring retainer is shown, which is constructed of wire or the like having two central straight portions 211 terminating in upwardly sweeping ends and spring loops 212, the ends then bending downwardly to constitute inwardly extending projections 215 which operate as do the projections in the embodiment first described. The connecting screws and lead-in wires pass between the straight sides 211, and these sides are conveniently gripped by grooves provided for them in the bottom of the insulating block 8.

While there has been illustrated a double ended spring, the operation of the apparatus would, of course, be the same if two separate springs were used or if a rigid member were used at one end and a resilient member at the other end of the heater.

While I have described the illustrated embodiarranged to grip a flat strand of hair adjacentits roots, a curler rod upon which the strand may be wound from its ends to the clamp, means acting between the rod and clamp preventing the,

unwinding of said strand, a heater comprising an arcuate shell, a heating element therein, a handle carried by an intermediate exterior portion of said shell, springs secured between the shell and handle and extending downwardly to overlie the ends of the shell, the ends of the spring being provided with inwardly extending projections arranged to resiliently grip the ends of the curler rod.

2. Hair waving apparatus comprising a clamp arranged to grip a fiat strand of hair adjacent its roots, a curler rod upon which the strand may be wound from its ends to the clamp, means acting between the rod and clamp preventing the unwinding of said strand, a heater comprising an arcuate shell, a heating element therein, a handle carried by an intermediate exterior portion of said shell, springs secured to the shell and extending downwardly to overlie the ends thereof, the ends of the springs being provided with a plurality of inwardly extending projections arranged to resiliently grip the ends of the curler rod.

3. Hair waving apparatus comprising a curler rod upon which a strand of hair may be wound from its ends to near the scalp, means preventing the unwinding of said strand, a heater comprising an arcuate shell, a heating element therein, a handle carried by an intermediate exterior portion of said shell, springs secured to the shell and extending downwardly to overlie the ends thereof, the ends of the springs being provided with a plurality of inwardly extending projections arranged to resiliently grip the ends of the curler rod.
