8 Claims.

This invention relates to hair curlersyand has for one of its objects the production of a simple and eflicient' releasable locking means for a hair curler to hold the rotating hair-gripping jaws in a set and non-rotatable position.

Another object of this invention is th production of a simple and efilcient hair-clamping means for use with the rotatable hair-gripping aws.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

By referring to th drawings it will be noted that I5 designates the hair-winding drum which comprises a primary jaw I6 and a secondary jaw I1 is hingedly secured, as at I8, to one end of the primary jaw I6. The jaw I1 is adapted to clamp down over the jaw I6 and to hold the hair in a clamped relation upon the drum I5, as the hair is wound upon the drum. The drum I 5 carries a winding knob I9 at one end for the purpose of rotating the drum I5 as the knob I9 is rotated. A hair-guiding member is used in association with the winding drum I5 and this guiding member 20 comprises a journal portion 2I which fits within a longitudinal socket 22 of th drum I5,

as shown in Figure 3. The journal portion 2| is provided at one end with an outwardly extending loop portion 23 Which extends beyond the outer end of the drum l5 and is provided with an inclined portion 24 for fitting into the radiating notches 25 formed at one end of the drum [5, as shown in Figures 3 and 5. This loop 23 terminates in an underlying leg 26 which extends under the drum I5 and is provided with an outwardly bent terminal 21 to which is pivotally secured a swinging latch 28. A parallel clamping rod 29 is fixed, as at 30, to the underlying leg 26 and the opposite end of the clamping rod 29 is provided with an outwardly inclined end 3|, as shown in Figure 4. This end 3| is adapted to be engaged bythe end portion 32 of the latch 28 and holds the rod 29 in clamped parallel relation to the leg 26 when the latch 28 is moved to the position shown in full lines in Figure 4. When the latch 28 is moved to the position shown in dotted lines in Figure 4, the rod 29 may be swung away from th leg 26 to. permit the hair which is to be wound upon the drum I5 to be fitted between the rod 29 and the leg 26.

I preferably provide a protector pad 33 of any suitable or desired material similar to that shown in Figure 10 and which fits under the guiding member 20 in actual practice, against the head of the user, and this protector pad 33 is provided with a suitabl longitudinally extending slot 34 which is adapted to register with the rod 29 and leg 26.

It should be understood that the pad 33 is placed against the head and a strand of the desired amount of hair is extended through the slot 34 of the protector pad 33 and between the rod 29 and the leg 26, and the latch 28 is moved to a locking position. The end of the hair is then clamped between the jaws I6 and I1 and the drum I5 is rotated, the guiding member 20 moving toward the pad 33 as the hair is wound upon the drum I5. By moving the drum I5 toward the inclined portion 24 of the loop 23, the notches 25 will engage the inclined portion 24 and lock the drum I5 in a set position. Th drum may be released by moving the drum I5 away from the inclined portion 24 for rotating the drum if desired, or for releasing the hair-curling device and removing the same from the head.

In Figures 6 and 7 there is shown a modified form of the invention wherein a winding drum 35 is illustrated comprising a primary jaw 36 and an auxiliary jaw 31. The primary jaw 35 is provided with an extending finger-grip 38 at one end and the primary jaw 36 is rotatably mounted upon the inwardly extending journal portion 39 of the guiding member 40. The guiding member 40 comprises a pair of parallel rods 4| between which the strand of hair may be fitted and the outer ends of the strands 4| terminate in a right-angularly extending enlarged loop 42 which may be gripped by the finger of the opera tor for spreading the rods apart to facilitate the placing of the hair therebetween. The opposite ends of the rods 4| terminate in an upwardly and outwardly extending loop 43 which projects in a plane at right angles to the loop 42 and constidrum 35 is being rotated. A retaining band 44 is used to hold the parallel rods forming the guide I 40 in assembled relation.

In Figure 10 there is shown a further'ernbodi ment of the present invention which illustrates a protector pad 45 upon which rests a clamp member 46 carrying parallel spring rods 41 secured and fastened together as at 48 by means of a staple, these rods 4'! fitting in a position to overlie the longitudinally extending slot 49 formed in the clamp member 46 and the, protector pad 45. Each rod 4'! is provided with a flaring outer end 50 extending in substantially parallel relation to the sides of the V-shaped notch 5| formed at the outer end of the clamp 46 and protector pad 45. These flaring ends 55 provide means to be engaged by the fingers of an operator to spread. the rods 41 apart and to facilitate the placing of the hair therebetween.

In association with the structure illustrated in Figure 10, I provide a special winding drum and locking mechanism, the winding drum being indicated by the numeral 52 and comprising a pair of

clamping jaws

53 and 54 of a suitable type. A collar 55 is secured at one end'of the drum 52 and an operating key 56 is carried by the drum 52 to rotate the drum within the collar 55. The primary jaw 53 of the drum 52 is provided with a latch-receiving portion 51 at the end opposite to the key 56. This latch-receiving portion is providedwith a pair of cross-notches 58. A looking bar 59 is pivotally secured, as at 60, to the collar 55 and is adapted to lie snugly against the drum 52, as shown in Figure 8. A pivoted latch 6| is secured to the outer end of the locking bar 59 and this pivoted latch is adapted to selectively fit in one of the cross-notches 58 of the latchreceiving portion 51 and hold the drum 52 .in a selected rotated position. The end of the latch 6| is bent laterally as at 62, and again bent backwardly in the opposite direction; as at 63, to provide a finger-engaging portion to facilitate the placing of the latch 6| into and out of engagement with one of the selected cross-notches 58.

Figures 11 to 13 inclusive, it will be noted, illustrate that the winding drum 52 carries a key or thumb-engaging portion 56, and the collar 55 is loosely mounted upon the drum 52 so that the drum 52 may be freely rotated in counter-clockwise direction within the collar 55. The latchreceiving portion 5! is carried by a shank 5'| which shank 57* is fitted within the socket 64 .formed in the 'drum 52. This shank 64 carries a ratchet coil spring 51' one end of which is adapted to frictionally contact the inner wall of the socket 164 and prevent the rotation of the drum 53 in a clockwise direction and permit the rotation of the drum in the direction of the wind of coil 51 or in a counter-clockwise direction when the finger-engaging portion embodying the elements 62 and 63 are gripped between the thumb and the first two fingers of one hand of an operator, and when the turning key 56 is gripped between the thumb and first finger of the other hand of the operator. The locking bar 59 is attached to the collar by a fixed pivot 55 at one end and is attached to the latch 6| by a fixed pivot 5| so as to firmly anchor the ends of the locking bar 59, but at the same time, because of the spring characteristics of the bar 59 this bar may flex outwardly, as shown in dotted lines in Figure 13, as the hair is rolled about the drum 52.

It should be understood that a very simple and efiicient hair curling device is provided which may be very conveniently and quickly locked in position, and which may be used in association 7 with the guiding element to facilitate the winding of hair upon the drum, at the same time efiicintly supporting the drum in a position to hold the hair in a wound position upon the drum and closely against the head of the user.

Certain detail changes in the mechanical structure may be employed without departing from the spirit of the invention so long as such changes fall within the scope'of the appended claims.
