2 Claims.

This invention relates to hair curling apparatus for use in so-called permanentwa-ving'and it is among the objects of the invention to pro- 'vide a device for curling the hair in an efficient and expedient manner and which shall be adapted to subject the hair to proper tension while it is being wound for curling.

One method of so-called permanent waving consists of segregating a tuft of hair and winding it around a spool-like member while simulta'neously subjecting it to tension, then while retaining it on the spool subjecting it to heat for a suitable period of time so'that when the spool is subsequently removed, the hair will retain its curled shape.

In accordance with the present invention, means are provided for the mechanical handling of the tufts of hair, particularly while it is wound preliminary to heat treatment to subjec't'all of the strands to uniform tension without pull or strain on the scalp, and to this end a special frame is provided for supporting the spool in winding the strands while permitting it to'slide on the frame with a regulable amount of friction to produce the desired tension.

The invention further consists in improvements for preventing burning or heating of the scalp and in an improved clamp'for holding'the strands of hair adjacent the scalp and further provides a support for the spool winding frame 'mounted to be universally movable relative to the head of the person on which the curling device is used.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawings constituting a part hereof in which like reference characters designate like parts and in which:

Figure 1 is .a plan view of a winding frame and spool together with a clamping mechanism in assembled position, the hair-winding device being illustrated as having the strands of hair partially wound thereon:

support and curling frame together with asteam boiler;

Figure 8 .a cross-section of a guard :plate;

Figure 9 aplan view thereof; and

Figure lO an end elevational View of the-guard plate.

Referring to Figure 1, numeral l represents the scalp from which strands of hair 2 havebeen An insulating block 5 is disposed between the clamp and the head to prevent burning of excessive heating of the scalp. Clamp 3 is constructed as shown in Figures 3 to 5-inclusive and consists-of apair of hinged members having heavy rubber sections 5 constituting the clamping faces which come together at 6, Figure '5. The strands of hair are disposed between the rubber clamping edges as shown at 1, Figure 3, and a latch 8 looks the hinge members in place in the manner shown in Figure 3. blocks is a bracket 9 having extensions ID for receiving grooves II and I2, Figures 1 and 2, of a spool l3, the latter being provided with a ratchet wheel M which engages a ratchet pawl l5 of the clamp, Figure 5, to prevent its rota tion when inserted in the bracket 9. The spool is provided with a spring clamp bar l6 which is hinged at'l'l' so that it may be raised as shown by dotted lines in Figure 2. The ends of the hair strands are placed between the clamp'bar 3 it and the face of the spool IS, the clamp having gripping engagement by spring arms l8 with the body of the spool to securely hold it in place.

The spool is mounted on a slide bracket 19 movable on a frame 29 made ofa cylindrical rod,

one end of the frame having a yoke 2| for receiving the clamp 3 which is snapped between the abutments 22. The yoke 2| is secured to the rods by pins 23 or in any other suitable manner. The slide bracket 19 is slidably mounted on the frame 29 and provided with tension means 24 for varying the amount of frictional contact of the slide bracket with the frame to thereby vary the tension on the hair strands 2 as they are being wound on the spool l3.

The slide bracket I9 is provided with journals 25 and 26 for receiving pins 21 and 28 respectively, the pins fitting in the openings shown in dotted lines in the ends of the spool 13, Figure 2 of the drawings. A ratchet pawl 29 is mounted on slide bracket I9 in alinement with ratchet wheel M of the spool to permit turning the spool in the direction of winding the hair strands thereon. By turning the knurled head 29 of the spool shaft, the spool will wind the hair strands and simul- Mounted on the top-face of the clamp d taneously cause the slide bracket IE to move downwardly on the frame members in the direction of clamp 3. The spool is then transferred to the bracket 9 of the clamp 3 and prevented from unwinding by the ratchet pawl l5. The frame 20 is disengaged and the wound hair strands are then ready for steam treatment. The frame member 20 is provided with hinged ear for engaging a link 3| that is mounted on swivel arm 32, Figure 7, which in turn is hinged on a post or standard 33 that is transportable to the chair on which the person to be operated upon is reclining.

When the wound spool is attached to the bracket 9 of the clamp, the frame 20 is removed from the clamp 3 and a steam box 34 is snapped on the clamp as shown in Figure 6, the edge of the box fitting against the rubber face of the clamp 3 to provide a sealed joint. The box is provided with a conduit 35 communicating with the interior of the steam box at 36 and a vent hole 31 is provided at the other end of the box. A hose 38 is attached to the conduit 35, the hose leading toa manifold 39, Figure 7. Steam is generated in a boiler 40 having a fire-box 4| with tubes 42 leading to the exterior thereof, water being supplied overtop of the tubes and steam dome in the same casing, and the steam generated passes through a pipe line 43 to the manifold 39. The top of. the boiler or manifold is open to prevent development of excessive steam pressure. A plurality of flexible hose connections 38, with springs wound on the inside or outside to carry the weight of the steam pocket, lead from the manifold 39 to a large number of steam boxes of the kind shown in Figure 6, each housing a wound strand or tuft of hair so that when all of the hair is Wound, the steam treatment may be applied simultaneously to all of them.

To prevent excessive heating or burning of the scalp, a protector plate 4, Figures 8 to 10 inclusive, is placed adjacent the scalp in the manner shown in Figure 1. Plate 4 is of concave shape at 44 and is preferably a wooden block 45 lined with felt at 46 and 41. The block is in two parts hinged at 48 similar to the clamp 3, and is provided with a latch 49 to hold it together. This block clamp functions to clamp the hair and aids in preventing pull on the scalp in the same man ner as the clamp block 3.

Referring to Figure 1, the spool 13 is interchangeable with slide bracket l9 and bracket 9 of the clamp 3 and is transferred from slide bracket l9 by withdrawing pins 21 and 28 after which it is placed in the bracket 9 and locked by ratchet wheel l4 engaging the pawl 15 of the clamp. The same frame and slide bracket is then transferred by movement of the swinging arm and link 32 and 3| to another portion of the head for winding another tuft of hair. By thus supporting the frame 20 and by maintaining suitable adjustment of screws 24, a uniform tension is applied to the hair while being wound, thus assuring uniform results of the waving after the steam application to the wound hair. steam treatment, the steam boxes 34 are removed from the clamps. The clamps are separated by unlatching the members 8 and the rolls I3 are unwound and clamp I6 lifted to free the hair which is then brushed out in the usual manner.

It is apparent from the foregoing description of this invention that the winding and curling device is compact and of simple construction and does not require any separate tension means as heretofore proposed, and by the use of the universal support the hair may be wound preliminary a minimum time with uniform been herein illustrated and described, it will be apparent to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.
