The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will. be obvious to those skilled in the art tc which the invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing-the preferred exemplification of the invention.

Referring in detail to the drawing, l5 denotes a device embodying the invention. The same includes a rotary curler part which may include a plurality of jaws [6, ll, pivotally interconnected at I8 and providing finger piece portions I9, 20 between which is seated a U-shaped strip spring 2| expansible for moving the jaws toward each other. Upon the jaw it there may be rotatably mounted a curler device so that it can be held in the hand while the jaw structure it, I! is rotated with the curler device acting as a bearing. 55

As thus far described, the structure is conventional.

According to the invention, the jaw I6 is formed as a grooved element, and it may consist of a tube having a slot 22 extending from the free end of the jaw to a point 23 at which the tube is circular in cross section, for reenforcement, being cut away in part at its other end to form the finger piece 2!). The other jaw H is of generally are shape in cross section and is formed with opposite ears for the pivot pin H! which extends through the tubular part of the jaw I6.

The companion part 24 of the hair curler includes a tube 25 having a strip element or spring 26 connected at one end 2'1 to the tube and having at its other end a catch 28 adapted to releasably snap into the adjacent end of the tube. The part 24 may be made as a one piece sheet material structure, with the material folded to provide a tube which is thus longitudinally split as at 29 at the side thereof facing the spring 26, and the latter being integrally struck out of said sheet material for the integral connection at 21. The tube 25 may have perforations (not shown) to facilitate drying of the hair.

The jaw I6 is inserted into the tube 25 which acts as a bearing for rotation of the jaws l5, IT, with the clamp 26 in open position. Upon pressing the clamp element 26 downwardly, the catch 28 passes through the groove or slot 22 to snap into engagement with the adjacent edge of the tube 25. Now the jaw l6 may be withdrawn with the catch 28 in closed position riding in the slot 22 until the jaw l5 has been completely removed.

To assure easy alinement of the catch 28 with the slot 22, the tube 25 may be provided with a tit 38 projecting releasably into a corresponding shallow recessed portion 3! of the jaw I 6 as shown in Fig. 6. When the operator feels the engagement or hears the click, she knows that the desired alinement has occurred. Any forcible turning will release the projection 30.

In Figs. 9 and 10 is shown a modification 32 which is generally like the device l5, except that the slotted jaw lfia externally engages around the tube 25a so that the latter acts as a shaft and the jaw [6a as a bearing. The operation of the spring and catch elements 26, 28 is the same as before. This device 32 is not as desirable as the device l5 because the hair is curled around the jaw I6a instead of directly on the tube 25a. Hence when the curl is withdrawn onto the tube 25a, it loses desirable tension because the tube 25a is substantially smaller in diameter than the jaw [6a.

In Figs. 11 to 14 is shown a modification 33, which permits alinement of the catch 28 with the slot 22 at all points of turning of the jaws so that the clamping spring 26 can be applied as closely to the scalp as possible. Accordingly, the detent such as 30, 3! of Fig. 6 may be omitted.

In principle, one jaw of the device 33 is journaled on the other jaw which is inserted into the tube of the clamp 24, and a projection on the tube 25 engages in the slot 22 to prevent rotation of the slotted jaw. For example, the tube 251) may have free end portions at 34 bent into the slot 22 for guiding engagement therein, as indicated in Fig. 13, but this will not prevent the engagement by the catch 28 as hereinbefore described.

The slottcd jaw lGb may have a tubular part, shown in Fig. 14, which is annularly recessed at to form a bearing. Engaged in this hearing is a ring or collar 36 which is thus held against removal. Fixed to this collar is a finger piece 31 which thus extends beyond the adjacent end of the jaw lGb. Pivotally mounted on the collar 36 at 38 is the jaw l'lb affording a finger piece 39. Thus while the jaw ilb is rotatable about the jaw iGb, the fingers 37, 39 are always in operative alinement and may be spring pressed apart by the U-spring 2!. Since the projection 34 is at the mouth of the tube 252) the sleeve jaw I612 is instantly easily alined for operation of its slot 22, irrespective of the angular position of the jaw Elb about the axis of rotation.

In operation, all the hair curlers shown are alike, especially those shown in Figs. 1 and 12. A strand of hair is engaged under the external jaw such as H, Ila, or lit, and the tube such as 25, 25a, or 25b held stationary while the jaw structure is revolved to form the curl. Then the spring element 26 is locked to retain the curl and the other jaw such as 16, ifia or I 62; removed, with the catch 28 riding in its adjacent slot and stripping off the curl of hair for tight, reliable retention thereof.

In Figs. 15 and 16 is shown a modified clamping device 40 comprising a pair 01 members 4|, 42 integrally interconnected at one end as by a resilient curved portion 43, and having at the other end interengaging means. The latter include a catch portion or nose piece 44 on the movable arm 42 for releasable snap engagement under the end of the arm 4|, which may be concaved at 45 as shown. Thus the device 40 may be very cheaply struck out of sheet material, with the arm 4| having sufiicient width to adequately carry a curl of hair wrapped therearound. This arm 4! may be regarded as longitudinally ribbed or otherwise reenforced.

According to Fig. 16, the arm 4| is coordinated with a jaw member IE or lfia or lfib so as to properly seat the latter for rotation, as, for instance, with the arm 4! having parallel edges diametrically engaging the interior of the jaw member. Thus the arm is disposed to afford space for engagement of the nose piece 44 under the edge 45 by merely pressing down on the arm 42. In operation, the clamping device 40 functions throughout like the device 24.
