7 Claims.

'I'his invention relates to improvements in hair curlers and it is the general object of the invention to provide a curler which can be easily manipulated and exert a uniform clamping action on the hair. Y

In the curling of hair it is customary to clamp theends of a lock` of hair between curling and clamping elements and then rotate them to wind -up the hair to a position as close to the head 10 as possible, after which a bobble pin or the like is used to hold the curled hair and the curler is removed. It is desirable that the clamping action be uniform throughout the length of the curling element and it is an important object of l5 my present invention to provide a clamp so mounted as to move uniformly toward and from the curling element, preferably by a parallel motion, thereby permitting the invention to be used veither with ne or coarse hair.

It is desirable to 'provide the curling element with a handle or the like by which it may be manipulated and it is a further object of the invention to mount the operating parts for the clamp within the handle.

It is another object of my invention to provide a hair curler which can be manipulated with one hand, this result being accomplished by a sliding head or the like operatively connected to the clamp so that movement of the head relatively to the curling element will effect movement of the clamp. This result may be accomplished by means of an inclined surface operatively interposed between the curling element and clamp and rendered effective by longitudinall movement of the head to space the clamp from the curling element. The head may conveniently be located at the end ofthe crler in an unobstructed posi- Y tion where it may easily be reached.

vWith these and other objects in view which will appear as the description proceeds, my invention resides in thelcombination and arrangement of parts hereinafter described. and set forth in the claims.

In the accompanying drawing:

Fig. 1 is a perspective view of the invention,

Fig. 2 is a longitudinal section through the invention showing the clamp in hair holding position with the operating head extended,

Fig. 6 is an enlarged vertical section on line 6 6, Fig. 2.

Referring to the drawing, the body has projecting therefrom two hair engaging curling elements 6l and 62, respectively, which may be sep-l arat'ed by a slot 63'. 'I'he body is provided with an inclined bore 64 to receive a shank 65 of clamp 66. A second inclined bore 61 receives a light compression spring 68 the left end of which as viewed in Fig. 2 bears against the part`of the head 60 while the outer end bears against an up` turned part 69 of the shank 65. The end of the shank may be bent back as at 10 to extend substantially parallel to the shank and be received by a slot 1l formed in the head. The end 10 and slot 1l serve to guide the clampand hold the samev in proper operating position.

An operating head 'l5 slides over the cylindrical surface 16 of the head 60 and has passing therethrough a 'pin 11 which lies along the inner part of the upturned end 69 so that the latter is located between said pin and the outer hand engaging zone 18 of the head'. 'Ihe clamp may be in the form of a tongue as set forth in Fig. 2

and has a surface to engage a similar surface 8i on the curling element 62, the clamp in the present instance being located within the curling element.

In normal position'the spring 68 is expanded and holds the head in the relaxed or out position shown in Fig. 2, and because of the fact that, the axis of the bore 64 and the shank 65 are inclined with respect to the axis of the body and of the curling element the clamp will be in down position or against the clamping element considered as a whole. When ythe curler is to be used the operator will grasp the hair with the 'fingers against a rounded shoulder 85 and the palm against the zone 18 and give the head an inward movement against the action of the compression spring 68. This eiects a relative in` ward movement of the clamp with respect to the axis of the curling element, spacing the curler and clamp as shown in Fig. 4, after which the ends of the hair to be curled may be introduced vthrough the slot 63 and located under the clamp. 'I'he head 15 may then be released, whereupon the spring will expand to move the head outwardly and the clamp downwardly or against the clamping elementv due to the inclined relation already described relative* to the bore 6l and clamp 65. The curler may be rotated to wind Aup the hair around the curling element and a bobble pin inserted in the slot 68. Thereafter a slight inward motion of the head 6l relative to the 55 pressure is exerted on the by alparallelmotion,

body or handle il will releasethe hair ends and thecurlercanbewithdrawn.

Promtheforegoing itlwillbe seen that I have provided a simple hair curler-wherein the clamp "and curling element move'away fromeach other thereby sriopins of the ends of the hair A the hair engaging parts of the curler. 'I'he relative separation'of the. clamp with respect 'to the curlingunit is effected 'by means of anfinclined surface which is oblique'with respect to the body l or handle, and kclamp moves with. respect to the axis of thej curling element.` A light compression'spring acts to returntheclamp into holding relation withl respect to the curling element, and furthermore there is'a head to be manipulated preferably by the palmof one hand of-the user and effective when pressed toward the curling element to move the clamp away from the said element to deilne a space yor slot for the introduction of hair ends.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departother element slides against the yielding means to -move the elements away from each otherv when I donot wish to ing from the spirit and A scope of the invention and v be limitedto the details herein disclosed, but what I claim is:
