10 Claims.

This invention relates to hair curling appliances, such as used in beauty shops for perma nent waving, curling, and the like, of womens hair. More particularly, the invention relates to a novel hair winding mandrel effective to secure better and more uniform distribution of the hair and more effective penetration of the treating solutions into the hair.

It is a primary object of this invention to provide a simple and inexpensive mandrel for winding womens hair, in which the hair is distributed substantially uniformly along the mandrel when the latter is latched in an operative position.

Another object is to provide a mandrel possessing the aforesaid characteristics and which is decreased in effective diameter, in the latched position, to provide for uniform spreading of bunched hair.

A further object is to provide such a mandrel having a longitudinally concave surface of stretchable material so that, when the surface is longitudinally extended, its diameter is substantially decreased.

These, and other objects, advantages and novel features of the invention, will be apparent from the following description and the accompanying drawings. In the drawings:

Fig. 21 is an elevation view of a mandrel, similar to that of Fig. 6, in the extended position, and incorporating a modified form of latching means.

Fig. 22 is an elevation view of the mandrel of Fig. 21 in the retracted position.

Figs. 23 and 24 are partial longitudinal sectional views of the mandrel of Fig. 21 in the extended and retracted positions, respectively.

Fig. 25 is a perspective view of the latching means of the mandrel of Figs. 21 through 24.

In accordance with the present invention, a stretchable winding surface is provided in combination with internal core or rod means. The surface is longitudinally concave and, in its retracted position, has a conforming fit over the core element or elements. The core or rod is longer than the surface, and extends therebeyond.

The surface is secured, intermediate its ends, to the core or rod, and interengageable latching means are provided between the ends of the mandrel surface and the extensions of the core or rod. The surface may thus be stretched longitudinally, and latched in the stretched position. This stretching effects a reduction in the effective cross-sectional arc or diameter of the surface. At the same time, the stretching surface carries with it the inner hairs, effecting a spreading out of the hair mass to achieve more uniform distribution of the hair along the mandrel. At the same time, the decreased diameter of the mandrel effects a loosening of the hair strand thereon.

The result of these two actions permits ready penetration of the relaxing and neutralizing solutions, used in hair treatment, to the very ends of the hair. Also, the body heat, under the customers cap, penetrates to the hair ends accelerating and intensifying the action of the solutions to a much greater extent than in the case of an unexpanded, wound up section of hair.

Referring to Figs. 1 through 5 of the drawings, the Winding rod or mandrel 3B is illustrated as including a winding surface 35 mounted on a rod til. Surface or mandrel 35, in the embodiment shown, is made of rubber and has a longitudinal concave outer surface and an axial passage 3! receiving rod 40. The surface decreases in diameter from its ends toward its mid-point.

Passage 3! is formed with an enlargement 32 receiving a central collar 33 on rod 49. The midpoint of mandrel 35 is thus fixed against movement along rod 450. The ends of mandrel 35 are notched, as at 34 to form heads 38 over which are fitted metal or plastic ferrules 31.

The ends of rod 58 project beyond heads 35, particularly in the retracted position of mandrel 35, as indicated at Secured on each end of rod Mi is a clip 39 of metal or plastic and having bent fingers .5 for snapping into notches when mandrel 35 is stretched as shown in Figs. 2 and 4. Thus, mandrel 35 may be latched in the stretched position by engagement of clips 35 over ferrules 37.

In operation, a strand of hair is wound on the mandrel while the latter is in the contracted position shown in Figs. 1 and 3. Mandrel 3 5 is then stretched until clips 39 snap over heads 35 and ferrules 31. In such stretching, the rubber mandrel spreads out the inner hairs of the strand. Also, mandrel 35 thins out, as shown in Figs. 2 and i, so that the previously tightly wound hair strand is loosened somewhat and the hair more uniformly distributed over the mandrel.

Figs. 6 through 9 illustrate a modified construction in which the winding mandrel comprises a relatively thin rubber sleeve fitted around a pair of relatively rigid core members it slidably mounted on rod 4%. Core members 15 decrease in diameter from their outer ends toward their inner ends, which latter abut collar 33 on rod 40. The outer ends of members 46 are notched or grooved, as at l! to form heads 46. The ends of sleeve mandrel :35 are suitably crimped or clamped into members lfi adjacent grooves 3?,

as indicated at 49.

Sleeve 45, in the retracted position, holds members against collar 33, so that extensions 88 of rod 48 project beyond the members 45. Clips 39 are secured on the ends of rod 49, as previously described. Consequently, mandrel 45 may be stretched by grasping heads 48 and snapping them into clips 39. This stretches sleeve 43, thinning it out. At the same time, as members A6 are moved outwardly, sleeve 48 becomes smaller in diameter adjacent its mid-point, as shown in Fig. 7. The hair is thus spread and loosened, as previousl described.

Another form, which the mandrel may assume in practice, is shown in Figs. 10 through 15. In this embodiment, a rubber sleeve winding mandrel 50 is snugly fitted over an inner core 55, both the mandrel and core having corresponding longitudinally concave outer surfaces.

Core has formed at its extremities reduced extensions 52 over which are fitted substantially rigid washers 53. These washers have flanges 54 which are turned in at their outer edges 53 to bite into thickened end portions 5? of mandrel 50. 58 pivotally secured thereto for movement parallel to the washer.

The mandrel operates in the following manner. In the contracted position of rubber sleeve 5% (Figs. 10 and 12) latch members 5% lie alongside extensions 52 as seen in Fig. 14. When sleeve 50 is stretched (Figs. 11 and 13) members 58 are swung to the diametric position, shown in Fig. 15, wherein they engage the ends of extensions 52 and retain the sleeve in the expanded position. In expanding, sleeve 53 thins out to loosen the coiled hair, and spreads the inn-er layer of hair, while remaining concentric with the core at the body portion thereof carrying the wound hair. 59, the same being resilient, returns from the position of Fig. 13 to that of Fig. 12.

Figs. 16 through 29 illustrate a form of winding rod identical with that of Figs. 6 through 9 except for the use of a different sleeve con- Each washer also has a stiff latch member Upon release of the expanded sleeve iii) struction and minor alterations in the slidable core members. In this arrangement, the winding mandrel comprises elongated, pleated and circumfcrentially spaced extensible strips 50, such as paper, plastic or thin metallic material, each secured at its inner end to collar 33 of rod 40 and at its outer end, to one of the slidable cores 46.

Cores 46 are formed with longitudinal grooves 61, each receiving a strip 60. The strips are secured to core members 46 adjacent notches 11, as indicated at 62. The strip inner ends may be secured between collar 33 and rod 40 in any suitable manner.

Desirably, strips 60 are suniciently stiff and resilient that they retain cores 48' in the retracted position of Figs. 16 and 18. When the strips are extended or stretched, heads 48 are snapped beneath clips 39 on rod 40 to retain the strips extended. In expanding, the mandrel composed of strip 66 contracts laterally to loosen the tightly wound hair strand. At the same time, it spreads out the inner layer of hair in the same manner as do the rubber mandrels previously described.

The arrangement shown in Figs. 21 through 25 is likewise substantially the same as that of Figs. 6 through 9, but incorporates a different latching arrangement. As shown, core members 46" are mounted slidably on rod 40 and abut collar 33 in the retracted position. The core members decrease in cross-section from near the outer toward the inner ends to provide a longitudinally concave periphery.

Sleeve mandrel 45', of rubber, is fitted over members 3% and likewise has a longitudinally concave outer surface. Core members 46" have cylindrical ends '66, and metal or plastic collars t? clamp sleeve 45 to ends 66. Each collar 61 has an arm 68 extending diametrically thereof. Arms 88 have apertures 69 fitted over rod 49 and slightly larger in diameter than the rod.

Arms 68 are resilient and normally are cooked relative to rod 48 so that the edges ll, 12 of aperture 69 bite into the rod. This retains the members 46" fixed along rod All. When sleeve mandrel 45' is contracted, members 46 abut collar 33, (see Figs. 22 and 24). In operation after winding, the arms 68 may be loosened by pressure on turned ends 73, and cores 48" slidingly drawn outwardly on rod 4!] to stretch sleeve 45'. The arms 68 are then released, and edges H, 12 thereof bite into or crimp rod 40 to retain sleeve mandrel 45 stretched.

The described hair winding rod or mandrel is eflicient and effective in operation, and the latching means may be quickl and easily engaged and disengaged. This facilitates successive use of the mandrel.

When a swatch of hair is wound on the mandrel, the movement of the hair is two-fold when the mandrel is stretched. Not only are the hair strands separated but also each half of the swatch assumes the form of a mitigated spiral, with the two spirals symmetrical and having their apices adjoining the center of the mandrel.

There is thus obtained a curl representing a Croquignole modified. by a bi-lateral spiral mover ent of the hair during expansion of the mandrel. This effect is apparent in the finished curl as a curvature of its ridges and grooves nearly parallel to the natural curvature of the scalp throughout the length of "the swatch. The aligned curls can be easily coordinated, in dressing the hair, as parts of a circular wave made up of will. be understood that the invention may be otherwise embodied without departing from such principles.
