Unite States Patent 2,977,960 rERMANENT WAVE DEVICE Frances L. Cattermole, Rte. 1, Box 99A, Terra Bella, Calif.

This invention relates to apparatus employed in hair waving, and more particularly to a hair Waving clip device for securing strands of hair to form curls therein.

A main object of the invention is to provide a novel and improved'hair Waving clip device which is simple in construction, which is easy to apply to the hair, and which is 'arranged so that the strands of hair engaged thereby are held relatively close to the scalp, whereby the clip devic'e may serve as a means to protect the scalp from possible irritation from hair waving lotion, and whereby the strands of hair are respectively held in a position to be clamped so as to form curls in the hair.

A further object of the invention is to provide an improved hair waving clip device which is inexpensive to manufacture, which is durable in construction, which is relatively compact in size, which eliminates. the need of using pins in conjunction with same, as has been heretofore necessary with hair waving clip devices of the prior art, which is provided with means for securely gripping the strands of hair thereover so as to form curls therein, and whi ch causes no discoloration of the hair or other undesirable elie'cts.

Further objects and advantages of the invention will become apparent vfrom the following description and claims, and fromthe accompanying drawings, wherein:

Referring to the drawings, 11 generally designates a hair waving clip device according to this invention, the clip device comprising a pair of flat, arcuate, opposing arnis, shown generally at 12 and 13, said arms having the concavely curved inner edge portions shownrespectively at14 andlS. Thus, the arm 12 comprises a pair of superimposed flat plate members 16 and 17, the bottom plate member 16 being formed with a longitudinal groove 18 which is covered by the upper plate member 17 when saidupper plate member is secured on the lower plate .member 16 by the use of suitable adhesive, or the like. Similarly, the arm 13 comprises the bottom plate member 19 on which is superimposed the top plate member 20, thebottom plate member 19 being formed with a longitudinal groove 21 which extends parallel to the groove 18 when the arms 12 and 13 are in their locked positions, as shown in Figure 2. The respective top plate members 17 and 20 are rigidly secured, by suitable cement, or the like, to the bottom plate members 16 and 19, whereby to define the unitary arms 12 and 13. The top plate members are formed at their ends with the respective notches 22 and 23, and the ends of the bottom plate members 16 and 19 are formed with upstanding apertured lugs 24 and 25 at said notches, the lugs having horizontal slots there in which are in registry with the longitudinal passages defined by the respective grooves 18 and 21.

The respective arms 12 and 13' are provided at their opposing arcuately curved inneredge portions 14 and 15 with a plurality of inwardly directed, opposing comb teeth, shown at 27 and 28, the teeth comprising overlapping segments integrally formed with the respective plate members 16, 17 and 19, 20.

The arms 12 and 13 are pivotally connected in overlapping relationship at their lower inner end portions, as viewed in Figures 1 to 4, by a rivet 30. At their opposite end portions, the arms are provided with the inwardly directed resilient finger elements 31 and 32, said finger elements being formed respectively on the end of the bottom plate member 16 and the top plate member 20, as shown in Figure 1. The finger elements 31 and 32 are provided at their free ends with the respective integral locking balls 33 and 34, whereby the arms 12 and 13 may be fastened together by forcing the balls 33 and 34 past each other to interlock in the manner illustrated in Figure 2, the resilient fingers 31 and 32 being sufiicient'ly flexible to allow the balls to pass each other. The arms 12 and 13 may be released by forcing the balls 33 and 34 outwardly with respect to each other, the flexible fingers 3'1 and 32 being yieldable sufficiently to allow this action to take place, whereby the arms 12 and 13 may be separated in the manner illustrated in Figure 2.

, As shown in Figure l, the top plate 17 is formed with the recess 50 at its lower end adapted to receive the end lug 51 defined in the subjacent plate member 20 by the provision of a recess 52 in the end of said plate member 20, whereby the plate members 17 and 20 are adapted to interengage when pivotally connected by the rivet 30. Similarly, the end of the plate member 16 is formed with a recess 54 in its end adapted to receive the end lug 55 defined on the end of the bottom plate member 19 by the provision therein of a recess 56, whereby the ends of the plate members are interleaved when pivotally connected by the rivet 30.

Similarly, the remaining ends of arms 12 and 13 are reduced to define spaced flat lugs 58, 59 and 60, 61 which are interengageable when the clip device is in its closed position, as shown in Figure 2, to insure that the clip device will be held in a flat condition when the locking balls 33 and 34 are lockingly engaged in the manner illustrated in Figure 2. The ends of the respective arms 12 and 13 are recessed, as shown at 63, whereby to receive the reduced end portions of the opposing arm, and whereby the top and bottom surfaces of the opposing arms are substantially flush with each other when the clip is in its closed position.

Designated at 35 is a generally U-shaped fiat resilient pin member having the flat side arms 36 and 37, said side arms being spaced to be slidably engaged through the lugs 24 and 25 and to be slidably received in the passages defined by the grooves 18 and 21. The arms 36 and 37 are formed at their ends with the respective hook elements 38 and 39 which are pivotally engageable with the lugs 24 and 25 when the pin member 35 is in its fully retracted position, whereby the pin member may be swung to an overlying position with respect to the main body of the device, as illustrated in Figure 4. The ends of the arms 36 and 37 are connected by the transversely extending flat rod-like bight elements 40 and 41 i which are spaced in the manner illustrated in Figures 1 and 4 and which are located to receive the locking balls 33 and '34 therebetween when the pin member 35 is in its external gripping position, shown in Figure 4.

As shown, the arms 36 and 37 are relatively flat and are adapted to closely'overlie the top surfaces of the arms 12 and 13 when the device is arranged in the position shown in Figure 4. The arms 36 and 37 are relatively flexible so as to yieldably grasp strands of hair 44 and to clamp the strands tightly against the top surfaces of the arms 12 and 13. The arms 36 and 37 are likewise flexible sufficiently so that they may be bent in the manner illustrated in Figure 3 when the pin member 35 is retracted from the device.

In using the device, the strands of hair to be curled are first engaged between the opposing comb teeth 27 and 28 and the device is locked in clamping engagement with the strands, the device being located in any desirable position on the users head, for example, closely adjacent to the users scalp. The arms 12 and 13 are locked in closed position by the locking engagement of the locking balls 33 and 34, as above described. The strands of hair are then held by the users finger while the pin member 35 is retracted and the hook elements 38 and 39 are engaged in the slotted lugs 24 and 25, after which the pin member 35 is rotated to an overlying position with respect to the strands of hair and is lockingly engaged with the locking balls 33 and 34 by forcing the balls through the space between the transverse bight elements 40 and 41. This clamps the hair strands to the top surfaces of the arms 12 and 13, in the manner illustrated in dotted view in Figure 5, and shown in full line view in Figure 4, whereby the strands of hair will be held in clamped position and whereby the required curls will be formed therein.

The clip device may be readily unfastened from the hair by reversing the procedure above described, first unfastening the clamping pin member 35 and then disengaging the locking balls 33 and 34 to allow the arms 12 and 13 to be swung apart and to release the hair strands. The various components of the clip device may be made of any suitable material, such as plastic material, preferably of a material which is chemically impervious to hair waving lotions and other preparations ordinarily employed in waving the hair. Various suitable materials are available which will meet the requirements, and such materials are well known to those skilled in the art.

The rod-like, transversely extending bight elements 40 and 41 are somewhat resilient and are sufficiently yieldable to allow the locking balls 33 and 34 to be forced therethrough, under pressure from the users fingers, and are likewise sufficiently yieldable to allow the locking balls 33 and 34 to be disengaged therefrom when the device is unlocked. As shown, the outer rod-like member 41 is arcuately curved to provide a smoothly curved end loop for the pin member 35, whereas the transverse inner rod-like member 40 is relatively straight.

The clip device of the present invention is superior to previous devices proposed for securing hair to form curls therein, because the device does not form a kink in the hair strands but instead merely holds the curl in a natural curved configuration, which is the desired wave configuration. Furthermore, the resulting hair wave is closer to the scalp and lasts longer.

The clip device of the present invention protects the scalp from contact with and irritation from permanent wave lotion, and also protects the hair from discoloration from chemical action of the permanent wave lotion with metal, since the device is made of relatively inert plastic material.

Obviously, the clip device of the present invention may be used either professionally or in the home.

The clip device may be readily employed with hair which has been previously bleached or dyed, since the hair strands 'may be curled in either direction in the clip device. Bleached or dyed hair can be only successfully waved if curled in a particular direction due to the fact that the natural physical properties of such hair are somewhat impaired, and that the chemical action of permanent wave lotion makes such hair relatively brittle, causing the hair strands to break off if curled in the wrong direction.

While a specific embodiment of an improved hair waving clip device has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
