13 Claims.

This invention relates to improvements in the yart of waving human hair and has particular reference to holding devices for a wound strand of hair.

In the prior Patent No. 1,919,282, issued July 25, 1933, there is disclosed a holding device for a strand of hair including a clamp and a curling rod in which the clamp is utilized to grip a strand of hair close to the scalp and to receive the curler rod upon which the strand is wound. In this holding device, the hair was adapted to be treated by a moistened pad and a heater to cause a permanent waving effect.

The clamp,y included a pair of pivotally connected elongated members brought securely together by a latching device to hold the hair strand therebetween.

The clamp, in the form shown, was provided with spaced pivot mounts for the curler rod and cooperating ratchet means to enable the curler rod to be wound up under tension.

The cooperating ratchet means, as disclosed in said patent, consisted of a ratchet formed on one end of\ the curler rod and a pawl carried by the clamp which is engageable with 'the ratchet so as to prevent rotation of the rod in a direction which would relieve the tension on the hair strand and allow it to become loosened on said rod.

The kpresent invention is particularly directed to a holding device of the character mentioned above in which the base of the clamp is formed of a molded piece vof bakelite or other plastic material while the other pivotally connected clamping member consists of a rubber covered metal arm and it is among the objects of the present invention to simplify the construction of the base and to enhance its strength without substantially increasing its weight or expense of manufacture and it is a further object of the present invention to provide a rubber covered metal arm member Which will automatically adjust itself to different thicknesses in the hair which is being held between said pivotally connected members.

It is still a further object of the present vinvention to provide a clamping construction in which the hair may be treated closely adjacent to the roots thereof without there being a substantial portion extending through the clamp and between the clamping members and the rod not subject to the proper treatment.

Other objects will be obvious or will appear during the course of the following specifications. In one preferred embodiment accomplishing the above mentioned objects, the base clamping member is formed of a relatively thin rectangular piece or plate of a molded plastic material, such as bakelite, which is peripherallyV slotted or grooved to receive a metallic reinforcing rib at one side face, the ratchet connection and one pivot mount at one end face, the latching member at its other end face and the clamping rod at the other side face, which clamping rod is pivotally connected to the ratchet structure.

The clamping rod itself preferably consists of a channel sheet metal strip receiving a sinuous spring member which channel strip is enclosed by another channel strip, the spring member tending to bias the two enclosing or enveloping strips apart.

Over the two channel strips is placed a rubber tube which rubber tube is adapted to be pressed into the groove or hollow in the side of the clamping bar by the latch arrangement Vabove described.

The mounts for the curling rod at the ends o-f the clamp are preferably so positioned that the center of the curling rod will be held directly over the front edge of Athe clamping bar with the result that there will be a minimum extent of hair between the clamping jaws and the curling rod not subject to the heat and moisture treatment.A

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for purposes of illustration is shown in the accompanying drawings, wherein:-

Figure 8 is an exploded perspective view showing thevvarious elements of the clamp upon enlarged scale.

Figure 9 is an additional exploded view of the clamping arm.

Referring to Figures 1 to 9, there is shown a heater A, a curling rod B and a clamp C.

The clamp C' to which this invention is particularly directed is provided with two clamping members, one clamping member D consisting of a base molded or formed out of an insulating material, such as bakelite, hard rubber or .some other plastic, and the other E of an arm pivotally connected adapted to be clamped against said base D by the latch F.

The base D also carries one pivotal mount G and the latch F carries the other pivotal mount H for the curling rod B.

The base D consists of an oblong rectangular shaped base of bakelite, hard rubber or other plastic material, the opposite long edges of which are provided with longitudinal recesses I0, II and the short lateral sides of which are provided with recesses I2, I3.

The bakelite or plastic base D is preferably of relatively small dimension, for example, 5%; of an inch in width, 2% inches in length and of an inch in thickness, in order to assure inexpensiveness and light weight in construction.

The base D is most desirably reinforced by placing in the slot I0 the closely fitting metal strip or plate I4 which is riveted in position by the drive. screws I5. (See Figures 3 and 8).

The strip or plate i4 terminates at I6 without extending into the slot I3, but is provided with a forward extending flange II at its other end which fits into the side slot I2 and projects beyond the base D to form the holed ear IB, said ear serving as a pivot mount for the swinging clamping arm E.

The end of the plate I4. is provided with the upturned flange portion I9 which covers the end of the base D above the slot I2.

The upturned portion I9 has the extensi-on 29, a portion of which is bent sidewardly as indicated at 2l to form a finger piece and the forward portion of which has an outwardly projecting finger 22 forming the semi circular recess 23. This recess 23 receives the full diameter end portion 24 of the curler rod B adjacent the ratchet 25. The end portion 24 also receives the pivotal connection 26 of the finger 2l' which is adapted to cooperate with the concave and roughened center portion 28 of the curling rod B (see Figures 1 and 7).

The slot I2 and the adjacent end of the slot 'I9 are made of increased depth to receive the extra plate 29 which may be riveted or spot welded, as indicated at 39, to the terminal portion of the reinforcing plate I4.

The plate 29 is provided with an extension 3i which extends forwardly and then is upturned, as indicated at 32, to form the finger piece 33 at the upper end of portion of which piece 33 `is cut inwardly to form a pawl 34 (see Figures 3 and 8).

The pawl 34 is adapted to engage the teeth of the ratchet 25 and it has suflicient resiliency normally to rmly engage with said ratchet teeth 25.

The end of the curling rod 2'I ,is squared, as indicated at 35, and is adapted to receive a key (not shown) to enable the ratchet 25 to be turned up in the direction indicated by the arrow 35 on Figure 1 to tighten the hair upon the curler rod B.

At the same time, the finger piece 33 has sufficient resiliency so that by placing the index finger upon the finger piece. 2I and the thumb upon the finger piece 33, the pawl 34 may be released in turn releasing the curling rod 28l and then the curling rod 28 lifted out of position.

The ratchet 25 and the curling rod 28 may be readily placed in position by pressing the pivotal portion 24 thereof into the recess 23, the resiliency of the spring finger 33 permitting the pawl 34 to slip into position on the ratchet teeth 25 (see Figure l).

It will be noted that the base structure D is somewhat extended below the slot I2 as indicated at 31 to support the flange 3I which carries the pawl linger piece 32.

It will be noted that the semi-circular recess 23 is centered over the front edge of the bar B so as to reduce to a minimum the length of the strand of hair clamped between the bar B and the arm E and coiled on the curling rod 28.

The ear i8 is enclosed between the bored jaws 33 extending from channel frame. member 40. The pin 4I extends through thevcoinciding holes or openings in the jaws 38 and ear I8 and serves as the pivot mount of the swinging arm E.

rIhe pin 4l is carried on the resilient leaf 42 which is pivotally connected at 43 to the outside channel member 45 which closely fits over and encloses the open side of the channel member 4U.

Enclosed in the channel member 40 is thesinuous spring 45 which is held in position by the pin it? (see Figure 9). The rear portions 48 of said sinucus spring abut against the back edge 49 cf the channel member 40 and the front portions 55 abutting against the front edge 5I of the outside or enclosing channel'member 45.

It will be noted that the channel member is recessed at 52 between the shoulders 53 and that the outer channel member 45 fitted over this recessed portion, the two channel structures 40 and 45 being biased apart by said spring 45, that the outside channel structure 45 being loosely mounted on the inside channel structure 45 so that a swinging movement between said channel strucires may readily take place.

The two channel structures are held together and are enclosed within the rubber tube 54, the embossrnents or knobs 55 stamped on the edge 5I of the U-shaped structure 45 assuring that such rubber tube will have an enhanced gripping face in respect to the hair when it is forced into the recess iI of the base D.

The recess ii of the Vbar D is provided with a series of steps 55 which terminate in the end groove 5l at the base of said recess, said steps 55 and bottom groove 51 extending the length of the bar D.

To the jaw members 68 at the other end of the inner channel member 4Q is pivotally connected the ear 58 of the latch F by the pin 59.V The ear 58 is positioned on the end of the plate member @i which fits into the slot I3 at the end of the base D.

The element 8l carries the pivot mount H on an upturned vertical end flange 62. The flange 62 is provided with an upstanding portion 63 having the semi-circular recess 64 which receives the bearing stud 55 at the other end of the curling rod (see Figure l) extending away from the large diameter portion 6B which is held inside vof the upstanding portion 53.

The other end of the bar 6I is provided with an CII ear el iitted between the jaws 68 at the end of the iinger member 1I. The jaws 68 of said clamping bar F have vertical ange portions 69 to nt into the recess 1li at the corner of the bar D, the end of the metal insert plate I4 being correspondingly recessed as indicated at in Figure 8.

It will be noted that the flanges 69 and the recess l@ are eccentric so that when the lever 1l is clamped against the face of the bar D, as indicated in Figure 3, the rubber sheath 54 will be clamped into the recess ll and tightly hold the hair therein.

In operation, the end of the tress of hair to be subjected to the Croquignole or other permanent waving operation may be placed under the nger 2i after the tress of hair has been selected and clamped between the swinging arm E and the base plate D.

rod B is turned until the hair has been all wound thereon'and then the curling rod B with the hair thereon is placed in position in the recesses 23 and 54.

As the curling rod B is placed in position, the pawl wi snap on to the ratchet 25 and by the application of the key to the squared nut 35 of the curling rod the hair may be tightened up.

Then, a pad may be placed over the hair on the curling rod B and then the heater indicated by A may be placed in position thereon and permitted to remain there for a desired length of time to cause the liquids on the pad to penetrate into and cause a thorough treatment of the hair with steaming.

The pad may consist of a piece of flannel or felt impregnated with a suitable liquid and prelerably backed by a sheet oi metal foil and an impermeable paper cover, the felt or flannel being placed on the inside against the hair on the curling rod B and the foil and paper being placed on the outside and the paper contacting with the heater A.

The heater A consists of two partial cylindrical magnesium alloy (containing small amounts of aluminum and manganese) jaw, members 85 which are outwardly bowed in their central portions to accommodate the shape of the hair. To the cylindrical elements 85 are connected the sheet metal arms 88 by the disks 85 and thev rivets Si.

These sheet metal arms 88 are provided with inturned ears 89 through which passes the pivot rod Sii, the upper portions of the arm structure being also connected at 9i to the bakelite handles of the finger pieces 92. The spring 93 fits arc-und the pivot rod and maintains the iinger pieces @Z and 93 apart, the jaws 85 together.

The construction and operation of the heater device A and the manner and means for preheating it and controlling its operation are not disclosed in the present application but forms the subject matter cf co-pending applications, Serial Nos. 62,094; 62,095; 69,641 filed February 3, 1936, February 3, 1936, and March 19, i936, respectively.

It is thus apparent that the present application has provided a clamping device of light weight, and the base D of which may be readily manufactured from or molded out of bakelite by readily available machinery with a minimum of cost.

clamping arm and latch F may all be inexpensively constructed from sheet metal and then subsequently assembled together and to cooperate with the base in a simple and convenient manner.

When so assembled on the base, the parts will not get out of order and will be extremely durable being capable of standing up over a long period of time although subjected to severe handling.

The resilient insertion 46 between the two channel shaped bar members 4E) and 45 which enclose each other enables adjustment of this arm E to accommodate the diiierent thicknessesv or distribution of the hair upon the curling rod B or passing between the clamping base D or clamping arm E and the clamping action will be more uniform for the entire length of the clamp.

In addition, the location of the pivot mounts 23 and 64 for the curler rod B directly over the front of the base D or the arm E of the clamp will lessen the extent of hair between that wound on the curler rod B and that clamped in position, so that a maximum length of the hair will be treated by the heater A and by the moisture of the treating pad.

It is apparent that the specic illustrations shown above have been given by way of illustr-ation and not by way of limitation and that the structures above described are Subj ect to wide variation and modiiication without departing .from the scope of intent of the invention, all oi' which variations and modifications are to be included within the scope of the present invention.
