6 Claims.

, 1. V This .invention relatesv to, clamps, employed for holding the hair. in .theprocess of waving and'it has: particular reference to an improveddevice adapted for use both in curling and'in straightening too wavy, or kinky hair.

The principal object of the'invention'isto' provide a device consisting of a pair of relatively pivoted arms, spring biased to clamping position onfthehair' and equipped with aclaspf tohpld the arms firmly inclamped relationship while theclamped lock of hair is'being rolled upon a split roller. or mandrelflwhich is subsequently brought into attaching relationship with the clamp. Moreover, thei'inventionanticipates a taperednibor 'projection'split into half sections; one'being' formed' on theupturned free end of each clamp arm and adapted; when the armsare closed, to define a spindle for reception in a" correspondingly shaped recess in one end of the roller whose oppositeend' is received in a-bifur (Cl. 132---40 )l cated'e'ar formed on one=of thec'lamp arms adja- I cent its pivoted end, thus enablingtheroller to more-securely hold the arms in clamping relationship while rotating the same to impose final tension onthe hair.

' Another object of theinventionis to provide a clamp as set forth in which the tapere'd spindle hasaformedtthereon a squared portion: at'itsbase which is adapted :to be received in aicorresp'ondinJgly-:.shaped section of. the. recess in the end of thee-roller; the latter beingprovided adjacent its: I

Adjacentthe deflection [3 of arml I is formed a semi-circularprotuberance i5 adaptedto.. be

received in the correspondingly shaped recess Hi (Fig. 3) provided in a companion arm ll of' the clamp. The arm I! islikewise formed: with? an angular deflection l8 confronting the :deflection 13 of arm II, which arrangement enables the ends of the arms to"be broughvtogetherwhen pivoted inthe manner'to-be'presently' explained. The angulardeflection' l8'of arm ll'isalsopro vided with an elongated. recess' [9. I

Formed perpendicularly on thearm 11 is a bifurcated ear 20,.1ocated immediately above the recess H3 in .theiarm; The-width of the ear20 is equal to the combined widths of the arniszll and I1 and oneend-oftheear overlies the arm H, thustolocate the center of the square rec'ess 2| of theeardirectly'overthe center of thesemicircular recessvlt" of. the'a'rm l1; Aehole 22:.is drilled in the ear 20 perpendicular to the-arm I1 and. this hole registers with ahole' 23 drilled in the semi-circular protuberance [5 of arm II whenthe. arms are assembled and a pin 24 is passedthrough the holes 22. and '23 to serve as a'pivot for the arms H and I1. It is' preferred that both ends of the pivot pin 24 be countersunk; as shown inFigure'S". :TP

A leaf-spring 25 1s disposed-with one, end-in the recess l4 ofuarm II and its:opposite endin recess. 19 0f arm I1 and exertsoppositeforces on the ends of the arms tendingto urge the' latter into clamping. r position. The arms are: spread apart". by finger pressure exerted on i the milled. surfaces 26 opposite the angular deflectiom'iof each of the arms.

The clamparm' ll has .an upturned end 21 identicalto theupturned end I2 of 'armJ-ir: Formedon'each upturned end l2- and 21 isa half-section 28 of a tapered protuberance, the protuberances becoming a spindle when the arms are brought together into clamping relatlonship. At the base of each protuberance is formed the half section 29 of a squared portion which latter serves as a means to prohibit rotation of the curlingroller 30 in the manner to be presently explained.

The curling roller 30 has a center portion of reduced diameter and is provided with an 61011-1 gated, transverse slot 3| opening at one end and terminating short of the opposite end of the roller in which the end of a lock of hair is received so that the lock may be wound tightly and uniformly on' the roller. A cylindrical head 32 is formed on one end of the roller 30 which is recessed to define a square cavity 33 (Fig. 2) and a tapered portion 34. end of the roller 30 is a portion 35 of the same diameter as the head 32 and, spaced toward the end of the roller from the portion 35 is a squared portion 36, the intervening space 31 being cylindrical in shape. At the extreme end of the roller is' formed a handle 38 by which the roller is rotated. This handle has roughened surfaces to prevent slippage of the fingers as the roller is being manipulated.

The clamp I is so placed on the scalp as to engage a selected lock of hair adjacent the roots.

The solution is applied to the hair and the ends thereof are placed in the slot 3i of the roller 30. The roller is rotated and the lock of hair is wound uniformly thereon until the roller is brought into juxtaposition to the clamp whereupon the roller is shifted endwise to engage its recess 34 with the tapered spindle formed by the half-sections 28. When the roller is thus disposed, the cylindrical portion 31 thereof will be in alignment with and will rest on the recess 2i of the car on the arm IT. This will hold the roller in proper relationship with the clamp while it is 'further rotated to impose added tension on the hair necessary to curl or straighten the hair, as the case may be.

When the desired tension is imposed on the hair, the roller is further moved longitudinally to engage the squared portions 29 of the tapered spindle with the squared portion 33 of the recess in the head of the roller. When thus engaged, the squared portion 36 of the roller will be brought into engagement with the square recess 2| of the car 20. The roller is thus held securely against further rotation while maintaining the required tension on the hair and further, the arms of the clamp are held firmly together by virtue of the engagement of the split spindle 28 by the hollow head 32. of the roller.

-When the clamp is initially placed on the hair, the arms II and I! are primarily held by a latch composed of a tongue 39 formed on one side of the arm I! and having a lip a adapted to engage over a rib 11 formed in a recess 40 in the companion arm II. This latch is sufficient to hold the arms together during the initial rolling of the hair but when the rolling operation is completed,'the increased tension requires a more secure retaining means for the clamp arm to prevent their relative displacement. This is supplied by the cooperating squared portions of the spindle and the squared cavity in the head of the roller.-

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims Spaced from the opposite the other half-section being formed on the upturned end of the companion arm, a squared portion formed at the base of each of said halfsections, an ear formed on one of said arms having a squarerecess disposed over the pivot of said arms, a slotted roller having a head provided with a recess having a tapered portion adapted in one position of said roller to rotatably receive said tapered spindle and a squared portion adapted to receive the squared portion of said spindle in another position of said roller to secure said arms in clamping relationship and to prohibit rotation of said roller and means on said roller engageable with the squared recess of said ear to hold said roller against rotative and lateral displacement with respect to said clamp.

2. A hair clamp and roller comprising a pair of relatively pivoted arms normally spring biased to closed position, an upturned end on each of said arms opposite their pivotal point, a protuberance formed on each of said upturned ends, said protuberances jointly forming a tapered spindle in closed position of said arms, a roller havin a head provided with a recess combining a squared portion and a tapered portion adapted in one position of said roller to rotatably receive said tapered spindle to hold said arms in closed position, a squared portion formed at the base of each of said protuberances, said squared portions adapted to be jointly received by the squared portion of the recess of said head in another position of said roller to hold the latter against rotation and means adjacent the pivotal point of said arms for receiving the opposite end of said roller.

3. A hair clamp and roller comprising a pair of arms pivoted together adjacent one end and normally spring biased into relative parallelism, an upturned 'end on each of said arms opposite their pivotal point, a protuberance on each of said upturned ends, said protuberances jointly defining a tapered spindle when said arms are in closed position, an ear formed on one of said arms having a portion overlying the other of said arms and provided with a squared recess in ali nment with the pivotal point of said arms, a hair roller having a recessed head receiving said spindle and provided with a cylindrical portion disposable in the recess of said ear in one position or said roller to hold said'roller rotatably in relation to said clamp and means operative in another position of said roller to hold the same against rotation with respect to said clamp.

4. A hair clamp and roller comprising a pair of pivotally connected arms movable into relative parallelism, each having an upturned free end, a protuberance on each of said upturned ends, said protuberances jointly defining a tapered spindle in closed position of said arms, ,a squared portion at the base of each of said protuberances, an ear formed on one of said arms at the pivotal point thereof having a recess, a hair roller having a cylindrical portion and a recessed head respectively engageable with the recess of said ear and said tapered spindle in one position of said roller to respectively secure said arms in closed position and to hold said roller rotatably in relation to said clamp and means formed jointly on said clamp and said roller to hold the latter against rotation with respect to said clamp.

5. The structure of claim 4, in which the ends of said arms next adjacent to their pivotal point are angularly deflected, the confronting deflected surfaces each being recessed, and a leaf spring of substantially V-shape having its ends lying in said recesses to normally urge said arms into relative parallelism.

6. The structure of claim 4, in which the means for holding the roller against rotation consists or a squared portion formed on said spindle ad- J'acent its base receivable by a squared portion in the recess in the head of said roller and a squared portion on said roller receivable by the recess in said ear.
