2 Claims.

This invention relates to a hair-waving appliance, especially to an appliance of the type comprising a clamping device including a body member with a clamping edge, and a swinging lever with a complemental gripping edge adapted to be swung bodily in an arcuate path around a pivot or fulcrum on said body member near one end of the gripping edges, having a latch on its free end to hold the edges in gripping relation with strands of hair of various thicknesses; and the invention relates more particularly to such an appliance in which the body member is provided with a spindle upon which the strand of hair is to be wound spirally.

In the operation of such hair waving appliances characterized by the aforesaid swinging gripping members, users thereof have experienced the disadvantage that while the clamping action upon a strand of hair of substantial thickness, for example, a strand on the top of the head, where the hair is naturally thickest, is quite adequate to hold the strand during the Waving operation; on the other hand, when a strand of hair from an equal are-a, usually a square inch, lower down on the head, is to'be treated, it is so much thinner as not to be clamped adequately.

The strand, thus insufliciently gripped, becomes loose and the treatment is unsatisfactory, as it is quite essential that the strand shall be tightly wound if a proper Wave is to be imparted thereto.

Another source of loose winding experienced in the use of appliances of the above type, arises from the f act'that the spindle upon which the hair is wound spirally, if mounted rotatably upon the body member of the clamping device, a provision which is desirable in order to permit the winding to be readily tightened, very often slips rotatively in a sense reverse to that of the winding, with unfavorable effects upon the efficacy of the treatment.

Under such conditions, it is an. object of the present invention to provide a means by which the swinging clamping member of such a hair waving appliance will automatically accommodate itself to strands of hair of different thicknesses, and will be held in equal-1y tight gripping engagement therewith regardless of the difierences in thickness.

Another object of the invention is to provide means for so rotatably mounting the spindle upon which the strand is to be wound spirally that rotation thereof is restricted to a turning movement only in the sense in which the strand of hair is wound on tightly; and as a corollary, its

rotation in the opposite sense, either intentionally or accidentally, will be positively prevented.

A cognate object is to provide such a rotation control that even if, after the strand has been wound on the spindle with desirable tightness,

the winding should be continued, no damage to a the appliance will result, nor will the hair be the drawing, in which:

and

Fig. 8 is a plan view of the knurled knob used to eifect rotation of the spindle.

In a now-preferred embodiment of the invention selected for illustration and description, the part designated by the reference character H is what may be designated briefly as the body member of a clamping device of known general construction, and formed of any suitable material, having one of its margins, as l2, formed with a gripping edge over which may be drawn a strand of hair from any desired portion of the head of the user, so that the member M will be disposed 45 with its flat upper surface it adjacent to, and approximately in parallelism with, the scalp of the users head.

As usual in this type of appliance, a complemental gripping member It, with a gripping edge 50 I5, is provided, taking the form of a lever which is mounted pivotally upon a suitable fulcrum l6, such as a lug disposed near one end of the gripping edge [2 of the body member, and around which the lever is adapted to swing in an arcuate 55 path until its gripping edge i5 is in close proximity to the gripping edge I2, with the strand of hair embraced therebetween.

In pursuance of the invention, means are provided to maintain this cooperative relationship of the gripping edges i2-l 5, in firm holding engagement with the strand of hair, regardless of whether the latter is of the thickness commonly found at the top of the head, or of a thinness such that the gripping edges are very closely assembled.

For the above purpose, I have illustrated as a convenient form of structure a latch device I l which is in general of known form, being pivoted as at 98 upon the free end of the lever l4, so that the latch swings around with the lever through its arcuate path, from the open, fullline position to the dotted line position. The latch is desirably made of relatively thin material, so that it fits snugly in a slot I9 formed for its reception in the end 29 of the body member !3 of the clamping device (see Fig. 1).

This latch arrangement of my present invention differs from the conventional arrangement of such latching devices in the important respect that instead of having its nose or detent portion 2i engaged with a smooth, continuous edge portion of the body member, as would be the case if the upper edge 22 of the member I3 had been continued straight to the right-hand end of the device as viewed in Fig. 2, the invention provides for selective engagement of the detent 2| with any of a series of notches or teeth composing an inclined, serrated locking edge 24 with which I have provided the portion 23 of the member l3.

Three of such notches are shown, but it is not intended to exclude the provision of two notches, nor a greater number than three, according to the requirements encountered in use. It is particularly to be observed that the pivot l8 by which the latch I! is mounted on lever i4, is so disposed that when the lever I4 is inclined at a Wider angle to the gripping edge l2, by reason of the presence of a relatively thick strand of hair in the clamp, and the detent 2| is therefore engaged with the right-hand notch of the series, or with the intermediate notch thereof, the latch itself will occupy an angle that will tend in itself to aid the maintenance of firm holding or retentive engagement between the detent and the selected notch; and it is also to be noted that the selection is performed in a purely automatic manner, and without the need for volitional eifort on the part of the user.

In pursuance of another stated object of the invention, the body member l3 of the clamping device is provided with a post 25 which is adapted to enter a socket 26 in the end of a spindle or curling rod 2? upon which the strand of hair is to be wound spirally in conventional fashion.

According to this feature of the invention, a coiled spring 28 is interposed in the socket between the walls thereof and the post 25, and acts as a one-way clutch to restrict rotative movement of the spindle 2'5 to rotation in the direction of winding the strand of hair thereon.

Upon reversal of such rotation, the ends of the coil spring are engaged with the walls of the socket and check such reverse rotation.

Even after the hair has been wound tight, the rotation in the proper direction may be continued without harm to the appliance or to the strand, as the spindle will slip within the spiral strand in that direction.

Under no circumstance, however, will the members 28 permit counter-slippage.

I have shown at 30 in Fig. 5 a knurled knob which has a central bore 3| of non-circular crosssection, adapted to receive a complemental end portion 29 of the spindle 21, and serving as a convenient means by which the spindle may be turned manuallyto wind on the hair.

The knob 30 can be readily removed for use upon another spindle of the series usually in service concurrently during any hair waving treatment, so that a single knob serves an indefinite number of spindles, and no spindle is encumbered by the weight of the knob, with an important advantage in comfort to the user, as there is not added weight pulling on a strand.

I claim:

1. A hair waving appliance of the class comprising a clamping device for embracing a strand of hair near the scalp, and a rotatable spindle mounted upon said clamping device and upon which said strand of hair is to be wound; said clamping device being characterized by a body part providing a mount for said spindle, said body part being of generally planiform shape,

and having a gripping edge and a serrated locking edge; a swinging clamping lever mounted pivotally upon said body member near one end of said gripping edge, being adapted to swing through an arcuate path into gripping alignment with said gripping edge, said swinging lever hav ing pivoted at its free end a latch member provided at its free end with a pivotally mounted, freely swinging detent adapted to be swung by manual pressure applied sidewise against said detent into easy self-adjustive selective engagement with an appropriate tooth component of said serrated locking edge, according to the thickness of the strand of hair at any time embraced between said clamping lever and the complemental clamping edge of said body member, and further characterized by having said serrated locking edge formed as a sinusoidal cam, and by having said detent formed with a recurved terminal having a round, complemental tooth adapted to travel smoothly over the serrated cam to and from the position of selective adjustment.

2. A clamping device for a hair waving appliance of the class described, said device comprising a planiform body member with a gripping edge and a locking edge disposed at a converging angle near one end of said body; and a gripping lever pivoted to said body at the opposite end of said gripping edge, said lever having pivoted to its free end a latch terminating in a detent adapted to be swung into engagement with any selected tooth of a sinusoidally serrated cam constituting said locking edge, the latter being formed on at least one wall of a pair of walls bounding a slot within which the shank of the latch is embraced as it swings to-and-from its adjusted position.
