i Claims.

This invention relates generally to apparatus intended to be used in conjunction with a heater, for waving hair. It relates particularly to apparatus of this kind which is clamped upon the hair in proximity to the scalp, to cooperate with a core or mandrel upon which the hair is wound.

It is a general object oi this invention to devise apparatus of simple construction, which can be readily clamped upon the hair, and which will 1Q permit the mandrel upon which the hair is wound to be positioned in close proximity to the scalp.

It is a further object oi this invention to devise apparatus of the above character incorporating a clamp having surfaces made of resilient material which serve effectively to engage a strand of hair.

1t is a further object oi this invention to devisehair waving apparatus which will serve to minimize transmission oi heat to the scalp.

1t is a further object of this invention to devise hair waving apparatus utilizing a hair clamp and a mandrel upon which the hair is wound, in which novel means is provided for properly positioning and supporting the mandrel upon the clamp so that the mandrel will not become unwound.

Further objects of this invention will appear from the following description in which I have set forth the preferred embodiment of my inven- 3otion. It is to be understood that the appended claims are to be accorded a range of equivalents consistent with the state oi` the prior art.

The present invention isin some respects an improvement over apparatus shown and claimed in my copending Patent No. 1,966,756. 1t can be outlined briefly as consisting oi apparatus which can be clamped to a strand of hair in proxn imity of the scalp, in conjunction with a mandrel upon which the extended strand oi hair is wound. Thus referring to Figs. l to '7 inclusive, my clamping apparatus is formed by a pair oi elongated members 11, which are adapted to be clamped together by suitable means to be later described. In the construction shown which has given good results, members 11 are formed by a pair of metallic strips 12 which are preferably bent to provide opposing U-shaped portions 13. Fitted within the U-shaped portions 13 and preferably extending substantially the entire length of the strips 12, I provide insert stripslli of resilient material, such as soft vulcanized rubber. In order to prevent the scalp from being heated to an unpleasant degree when using my apparatus, preferably provide strips 16 of heat insulating material such as Wood, which cover the lower faces of metallic strips 12. Wood strips l'can be suitably secured to metallic strips 12, as by means of pins 17. To the lower faces of strips 16 are preferably secured strips 18 oi felt, or other equivalent soit material,

As a means for securing together members 11, I have shown links 21, and these links are preferably connected to the metallic strips l2. Thus I have shown corresponding ends of strips 12 provided with tabs 22, pivctally connected to the end of links 21 by means of pivot pin 23. 'Ihe other corresponding ends of members 11 are adapted to be clamped together by means or links 24, having corresponding ends pivotally connected to a tab 26, by means or pivot pin 27. The other corresponding ends of links 24 have a pivotal connection with the locking lever 28, this lever having a cam portion 29 formed upon the same. Cam portion 29 is adapted to engage a tab or projecting portion 31, extended from one of the metallic strips 12. When links 24. are in the position shown in solid lines in Fig. 2, projecting portion 31 projects between the links 24, and by rotating locking lever 28 to the position shown in solid lines in Fig. 2, cam portion 29 presses against the corresponding edge of portion 31, to secure the clamp members 11 together. To separate members 11, it is only necessary to swing the locking lever 28 outwardly and swing links 23 free from portion 31, after which members 11 can be separated.

As previously explained, I prefer to employ my clamping apparatus with a mandrel 32, upon which hair can be wound. This mandrel is preferably substantially circular in cros section, and has an intermediate portion 33 oireduced diameter. A lug 34 extending from one end of the mandrel provides convenient means whereby the mandrel can be rotated by the operator. Upon the other end o the mandrel are ratchet teeth 36, Which are adapted to cooperate with a ratchet or pawl carried by the clamping apparatus.

In order to properly position the mandrel 32 upon the clamping apparatus, I provide upstanding support members 37 upon the uppermost of links 2l and 24. These members can be formed integrally with their associated links 2l and 24, and preferably have arcuate upper surfaces 39 adapted to nt the end portions of mandrel 32.

In order to prevent unwinding of the mandrel 32 when it is seated upon members 37 and 38, I provide a uitable pawl which is preferably mounted upon one of the links 21 or 2 In this case I have shown a pawl 41, formed of a spring metal strip carried by the uppermost of links 3i. In fact as shown in Fig. 5, it can be formed integrally with the uppermost links 24, by providing an integral extension on this link which is doubled back to form the pawl 41. The hooked end portion 42 of this pawl 4l serves to engage the ratchet teeth 36.

In utilizing my apparatus, a comparatively wide strand of hair is rst placed between members ll, when these members are separated as shown in Fig. 3. Members 1l are then brought together and clamped in position upon the strand oi hair by engaging the clamping lever 28. As shown in Fig. 8, this strand of hair is then wound up on mandrel 32, and the mandrel is then seated upon the support members 37 and 38, as shown in Fig. l0. As the mandrel becomes seated in members 3'! and 38, ratchet teeth 35 engage pawl 41, and a ertain amount oi added rotation serves to properl I' tension the hair while pawl 4l ratchets over teeth 36. When the mandrel is released tension on the hair sufficient to properly retain the mandrel upon the support members 37 and 33, while pawl 4l prevents unwinding of the mandrel. The hair in this condition is then heated by suitable means. For example I can employ an electrical heater such as shown in rig. l. In this case two curved heating elements 43 are engaged upon opposite sides of the mandufel, and serve to the hair and mandrel until the hair sets into the desired wave. Generally a cloth 43 is rst placed about mandrel 32 after which the heater is positioned over the same. ritter the heating operation and after the heating appliance 1las been removed, it a simple matter to release pawl 4l, as this can be accomplished by forcing one end of mandrel 32 to one side to cause teeth 36 to be disengaged from the 'nook 42.

In using app' ratus oi this sind it is general practice to use a vaporizable oil upon the hair, and vapors from this oil during the heating process are apt to be directed down upon the scalp. In my invention means is provi ed for permitting escape of these hot vapors from between the mandrel 32 and the rubber inserts 14. For this purpose I have shown auxiliary metal plates or strips 44, which are mounted in spaced relationship to the strips l". As a suitable mounting I have shown rivets 46 interconnecting strips 44 and 12, with washers 47 ior maintaining the proper spaced relationship. The inner edges of strips 44 preferably have upturned portions 48 to preclude cutting of the hair. Generally the lov-Jer edges of the heating elements 43 come in fairly close contact with the upper plates 44. Vapore evolved from the hair as the hair is being heated, can pass downwardly between the inner edges of plates 44 and then outwardly between plates 44 and strips 12.

The resilierrL insert strips 14 are an advantageous feature ci my apparatus since they provide positive contact with all portions of the strand. E" hermore these strips provide considerable friction in their engagement with he hair, without undue amount of clamping pressure. rhe mounting of support members and S8 upon links 21 and 31 respectively, is also advantageous feature in that it leaves the mer bers il substantially unobstructed, and it .-.lzcs catching oi the hair while members l1 are attached or removed.

I claim:
