YORK, ABSIGNOR 1'0 THE NESTLE-m Y., A CORPORATION OF OHIO HAIR WAVING APPARATUS Application am: June 1,

This invention relates to improvements in the art of waving human hair and has-particular reference to holding devices for a wound strand of hair.

Holding devices including clamps and curler rods have been heretofore devised wherein the clam is utilized to grip a strand of hair close to t e seal and to receive the curler rod upon which t 1e strand is wound. The clamp usually consists of a pair of pivotally connected bars adapted to be brought together to securely hold the hair strand therebetween, and is provided with means cooperating with the curler rod to tightly wind said strand thereon and maintain the latter under tension. The cooperating means customarily emplo ed consists of a ratchet formed on one en of the curler rod and a pawl carried by the clamp which is engageable with the ratchet so as to prevent rotation of the rod in a direction which would relieve the tension on the hairstrand and allow it to become loosened on said rod. With the strand of hair thus held between the bars of the clamp and wound on the rod, the lat ter is held against the clamp at least partly by the tension under which the strand has been-placed, and cannot conveniently be re moved until said tension is relieved. In the types of appliances heretofore used, the release of tension after treatment of the hair strand is accomplished by first separating the bars of the clamp after which the curler rod and hair strand may be shifted slightly in a longitudinal direction relative to the clamp in order to disengage the ratchet of the rod from the pawl of the clamp, whereupon the rod may be rotated to unwind the strand therefrom.

It has been found in practice that the separation of the bars of the clamp, preparatory to unwinding the hair strand after treatment,

' requires some skill in the proper handling ments of the pawl of the appliances as it entails the necessity of the operator holding both the clamp and the curler rod in order to accomplish the shifting of the latter to disengage the eleand ratchet mechanism.

In accordance withthe present invention it is :proposed to simplify the operation of releasing the hair strand from the curler rod by a suitable means the use of which will 7 avoid the necessity of the operator first separating the bars of the clamp and holding the same while shifting the rod and strand 1982. Serial No. 614,892.

relative to said clamp in order to disengage the parts of said pawl and ratchet mechanism one from the other.

In accomplishing this simplification it has been found satisfactory to provide the pawl with a finger-piece by which it may be released from the ratchet mechanism, and in one preferred form of the present invention such pawl is provided with an abutment which may be desirably located to serve as a finger abutment so as to-limit the movement of the pawl in releasing the ratchet.

he inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for purposes of illustration, is shown in the accompanying drawing wherein Figure 1 is a rspective view of the clamp and curler ro illustrating a hair strand in the act of being wound upon the rod while held by the clamp.v

Figure 2 is a side elevation of the clamp and rod in operative position, showing a heater applied thereto, partly broken away and'shown in section.

Figure 3 is an end elevation of the assen bly s own in Figure 2, also partly broken away and shown in section.

F gure 4 is a plan view of the clam Figure 5 is an end elevation thereo and Figure 6 is a perspective view of one of, the spring members employed with the heater.

he apparatus shown inthe accompanying drawing consists generally of three elements, namely a clamp 10, curler rod 11 and an electric heater 12. In use, the clamp is first employed to gri a strand of hair 13 adjacent the scalp, a ter which said strand is wound u on the rod 11, in the manner illustrated in igure 1. When the strand is completely wound upon the rod, the latter is unengaged with the clamp in a manner to be presently described in detail, and the strand is then wrapped in a pad or sachet (not shown) which is moistened with a hair treating solu-' tion. The heater 12 is then placed about the strand and heat applied for treatment of the strand in the customary manner.

The fresent clamp is shown, in its preferred orm, as comprisin the two cooperating clamping bars 14 am? 15, the former of ENT OFFICEJ which is made of a suitable insulating ma- I terial while the bar 15 consists of a metallic rod 16 covered by a sleeve 17 of rubber or other suitable insulation. The inner edge of gitudinally with supporting the rod on t the bar 14 adjacent the bar 15 is concaved as indicated at 18 (Figure 5) so as to receive a portion of the sleeve 16 to thereb provide maximum grip in surfaces for t e clamping bars which 01 the hair strand therebetween.

At the ends of the bar 14 the same has suit-- abl secured thereto the bearing members 19 an 20, the former of which is provided adjacent its base with a lug 21 to which is pivoted the ad'acent end of the bar 15. The other end 0 said bar carries a latching device consisting of a link 22 pivoted atone end to said bar and, in turn, having pivoted to its other end a cam lever 23. When the clamping bars have been brought into cooperative relation with the strand 13 therebetween the link 22 is swung to a position arallel with and against the adjacent end 0 the bar 14 and the lever 23 is then extended lonthe outer edge of said bar, as shown in Fi ure 1, to lock the clamping bars together. i Vith the clamp in its 0 erative position, be wound upon the curler rod 11.

The body of the rod is tapered inwardly from both ends as is customary with rods of this ty e and adjacent one end thereof has pivote thereto a retaining arm 24 which extends longitudinally of the rod and is adapted to have the free end of the strand interosed-between the same and said red at the Beginning of the winding operation. The strand is now wound upon the rod in the manner shown in Figure 1 and as the winding operation progresses clamp and finally contacts the same with the end portion 25 of the rod engaged in the recess 26 of the bearing 19 and the trunnion 27 at the opposite end of the rod engaged in the recess 28 in the bearin member 20, thereby efclamp. At the outer end of the portion 25 of the rod there is formed a ratchet 29 which is disposed exteriorly of the bearing member 19 when the rod is in osition and which is adapted to be enage by a pawl E the numeral 30 and carried by the bar 14.

his pawl and ratchet mechanism is designed to prevent rotation of the curler rod in one direction and at the same time permits of a turning of the rod in the opposite direction, by the application of a key to the squared end 31 of said rod, to tightly wind the strand 13 on the rod and thereby place said strand under the desired tension for the waving process.

The pawl member 30 ecifically comprises a base portion 32 secure in the adjacent end of the bar 14 and having extending upwardly from one end thereof the curved spring arm .33 which is of sufiicient length and resiliency to normally maintain the pawlor tooth 34 thereof in en agement with the teeth of the ratchet 29 an at the same time permit of the under which the latter the strand 13 is now rea y to the rod approaches the member generally indicated withdrawal of said pawl from the ratchet without undue pressure having to be exerted upon said arm. The latter is extend be end the pawl 34 to rovide a-fingerpiece 35 aii ording a means w ereby the operator may easily press the arm in a direction away from the ratchet 29 and thus disengage the pawl 34 from the teeth of said ratchet- To facilitate this releasing action the bearing member 19 is provided with a second fingerpi'ece 36 disposed in juxtaposition to the piece 35, and being stationary, said piece 36 provides a grip by means of which the movable fingerpiece can be more readily pressed in a direction away from the ratchet 29.

In the types-of clamps and curler rods usually employcd,when it becomes necessary to unwind the strand of hair from the curler rod after treatment of said strand, the tension has been placed by the operation causes such an interenga ement of the clamp and curler rod that in or er to conveniently release the latter from said clamp, the clamping bars must be first separated to relieve said tension. When this has been done, the curler rod with the strand wound thereon is free to be shifted slightly in a longitudinal direction relative to the clamp so as to disengage the ratchet on the rod from the pawl ofthe clamp, whereupon the unwinding of the strand from the rod by rotation of the latter may be accomplished. While performing this operation, the operator must hold the clamp while the rod is being shifted. In contradistinction, the present device provides a more simple and efiicient manner 0 releasing the curler rod for the purpose of unwindin the strand therefrom, inasmuch as it is only necessary for the operator to press upon the spring arm 30 to disengage the pawl and ratchet whereupon the strand may be unwound from the rod by a direct movement of the latter away from the clamp.

It will be noted in the construction shown it will not be possible for the operator to bend the pawl finger-piece 35 so as to unduly strain it, since when the pawl finger-piece 35 is moved sufficiently to release the pawl 34 from the .ratchet 29, such pawl finger-piece 35 will abut against the finger-piece 36. This feature is particularly important inasmuch as the resilient element is relatively delicate and ma be easily injured by excessive strain. It has en found that the squeezing movement necessar to release the pawl 34 by moving the pawl nger-piece 35 against the abutment 36 is most satisfactory, and is more susceptible to ready actuation by the operator.

When the finger-piece 35 is moved into contact with the abutment 36 which limits its movement, the pawl will be lifted out of the ratchet 29 which will then be free. It is to be understood, however, that the present invention also includes other relationships between the pawl finger-piece 35 and the abutwinding plates ment fingeroperator to p ace her thumb against one fin er- )iece and the index finger against the other an readily release the combination, as p viously described. It is also generally desirable to have both the abutment fin er-piece and the )awl finger-piece located ad acent to one of the bearing elements or members 19 attached to the end of the bearing 14 of the clampin member. The e ectric heater 12 is shown as comprising a pair of elongated heating elements 37 which are curved transversely and adapted to engage on opposite sides of the wound strand of hair on the curler red, as best shown in Figure 3. These heating elements are supported by upwardly converging 38 and to the intermediate portion of each plate is secured a handle 39 made of suitable insulation material and throu h which electrical conductors 40 extend or conveying current to resistance coils disposed within each of the heating elements 37 n opposite sides of each handle the associated supporting plate 38 is provided with the extensions 41 which diver e outwardly relative to the extensions on 51c opposed plate. Each pair of the opposed extensions of the respective 42 to receive a spherical member 43. These members on opposite sides of the handles 39 constitute bearings about which the handles have a pivotal movement so that the heating Elements 37 may be adjusted toward and away from each other.

To assemble the opposed heatin elements, their supporting plates and hand es into an operative unit and provide means for forcing the heatingelementstoward each other so that they will securely grip opposite sides of the hair strand, a contractile sleeve-like spring 44 is associated with each pair of extensions 41. .Each spring is split longitudinally so as to receive said extensions therebetween and thus exert a ressure upon the outer surfaces thereof wluch will normally force the heating elements toward each other. In order to prevent accidental displacement of the spring members alon one of its longitudinal edges, as indicated at 45, to provide at the ends of the sleeve a pair of lugs 46. The length of the cut out portion 45 is substantially equal to the width of the adjacent extension 41 so that the latter will engage in said out out with the lugs 46 overlapping the edges of the extension and thus preventing a lateral shifting of the spring member relative to the adjacent handles 39.

From the foregoing, that by compressing the free ends of the handles 39 the heating elements 37 may be spread apart against the action of the springs 44, preparatory to mounting the heater in operative relation to a hair strand, and that upon it will be apparent iece 36 which will enable the plates is provided with openings.

44, each of them is cut away I 4 ment of the release of said handles said spring members will be efi'ective to clamp the heating elements against the strand and thus maintain the eater in position for application of heat to the hair belng waved.
