HAIR` CURLER Filed Aug. 25, 1944 Patented Jan. 15, 1946 UNITED STATES PATENT OFFICE CURLEE Rudolf Krasberg, Chicago, Application Augusty 23, 1944, Serialllrlo. 550,692 6 Claimsl (CL12m-T34) The. `present invention relates to hair curlers and more particularly to an improved hair curler which will hold the curl from unwinding at any desiredl position on the strand of hair.

Heretofore hair curlers of a type comprising a bar on which a curl. may be WoundV have been provided with a suitable gripping member and a pivotedv loop-shaped locking member for restraining uncurling of the strand of hair Wound on the bar. Such type of hair curler usually uses a hollow bar which may be perfor-ated and which has a spring biased gripping or clamping member for engaging the end` of a strand of hair to bewoundupon the bar inthe form of a curl. A loop-shaped. locking member which is pivotally connected tothe bar restrains the curling motion but does not permit the curl to be wound tightly against the head of a person since in winding it is not possible to judge With great accuracy how many turns of the bar are required to form a. curl. Obviously av xed locking or restraining member therefor may be a fraction of a turn removed from a most desirable restraining position. Other types of hair curlers have been provided' with a hair pin like member inserted in the hollow bar, but such device is particularly disadvantageous when the hollow bar isof'the perforated type since it is diliicult to insert the hair pin like locking member into the bar since the perforated interior of the bar does not readily permit the placement of the wire member in the most desired restraining position. In` accordance with the present invention the above mentioned disadvantages are overcome byy providing a hair curler of the type having a barand a clamping or gripping member with a restraining member which is resiliently retained in thedesiredposition so as to have adequate inherent rotation resisting action relative to the bar.

It,Y therefore* is an object of the present invention to provide an improved hair curler with a restraining or locking member which obviates cer-tain` disadvantages. ofthe devices-of the prior art;

Othery andl further objects of the present invention. subsequently will become apparent by reference tothe following description taken in connection with the accompanying drawing wherein:

Figure 1 is a perspective view of ahair curler embed-ying the present invention asappliedv to a s tnrarngl oli-hair wound in the form ofA a` curl on thecurler;

nliligure lis-an enlarged: cross sectional view-o1BHL a portion of: the curler shown in Figure 1f, said section beingl taken longitudinally of the curler;

Figure 3 is a side view with an intermediate portion thereof broken away so as to. illustrate the structure at opposite ends of the hair cur-1er;

Figure 4- is a cross sectional View through the hair curler at right angles to the longitudinal axis thereof at a time when a strand of hairhas been formed on the curler and' tightened,y against the users scalp, the locking member serving at this 4time to restrainl theuncurling action ofthe eurle er; and` Figure 5 is a cross sectionalk View of the curler similar to Figure 4., showing. the` locking member released from the curl. so as to enable convem. ient longitudinal withdrawal of the curler.

Referring to the drawing therev is shown in Figure 1Y a strand of hair Illwound` in the formy of a curl la upon a hair curler having a bar. I4' anda cooperating clampingv or gripping mem-, ber I6; A loop-shaped locking member I8 is positioned so as to restrain the uncurling action of the curl I2.

The details of the arrangementgenerally shown-x in Figure-1` will become apparent from Figures 2f and 3 from which it will be seen that preferably the bar I4 is of the hollow perforated type, in` which case the gripping member IEm-ay-also be perforated. The gripping member I6: mayv be spring biased byra suitable spring Z'interposed. between a linger oper-ating portion 2'2 ofthe gripping member IB andthe body of the bar` I4. Oneend of the spring member 20 may be retained-inposit-ion byengagement with an up-structure portion` 24 of the bar I t or some other simi-lar restraining arrangement which ofcourse will be apparent to those skilled'in the art. The gripping member` I6 isA pivotally securedto the body l2- by a suitable rivet member 26. The end olf; the bar I d extendsv an appreciable distance b eyondjthe end of the linger portion I2-of the gripping' member I6 so as to providesuflicien-t length for supporting a frictionally retained rotatable sleeve mounting member 23 whichV is provided` with suitable-projectingportions 30 for pivotallysupporting the restraining or locking member- I8;

The sleeve 2 8' may have provided-at the interior thereof an annular-'recess 3 2 which isengaged-by a portion of a spring 311|,V mounted Within the eX- tension portion of the bar I4; One end ofthei resilient member 34 engages the inner surface of the bar I4 and the other end'thereofv projects-L through an aperture 36 so that the end ofthe springv mayY engage the annular recess 321701? the -supporting collar or sleeve 28. The spring 34 therefore serves to frictionally retain in position the sleeve 28 although by the application of sufficient force the sleeve 28 may be rotated so as to position the locking member I8 at any desired angular position relative to the bar I4. The locking member I8 at a short distance beyond the pivotal connection with the extensions 30 of the sleeve 28 is provided with inwardly curved portions 38 adapted to engage. oppositely arranged recesses. or slots 40 formed in the sleeve 28 for retaining the locking member I8 in thejlocking po sition shown in Figures l and 2.

During the time when the strand of hair IG is being wound into the form of a curl I2 on the bar I4 the locking member I8 is in its looked position as shown in Figure 2. In this position the locking member I8 is prevented from rotating with the bar I4 by the fingers of the operators hand. In other words, while the operator turns a ilnger grip cap 42 which is secured to one end of the bar I4 the Vother hand holds the locking member I8 against rotation. During this operation the curl is wound around the bar I4 and the gripping member I6, as illustrated in Figure 4. Due to the fact that the bar or tube I4 is adapted to be rotated relatively to the locking member or bale I8 the user may tighten the curl against the scalp to any desired degree. Once the curl has been tightened in the positionshown in Figure 4 it will retain that position and be prevented from uncurling by reason of the bale or locking member I8.- It should be understood that while relative rotation between the tube or bar I4 and the baleV I8 takes place during the initial'tightening of the curl, such rotation is continuously counteracted by the action of the spring 34 engaging the sleeve 28. This irictional engagement of the spring 34 with the sleeve 28 is suiiicient to prevent inadvertent or unauthorized uncurling of the strand after it has been tightened against the users scalp in the position illustrated in Figure 4. Thus during the time that the curl is drying and being set it is. prevented from uncurling and loosening by the action of the resilient member or spring 34 upon the sleeve 28. The users scalp isindicated by dot and dash lines in Figures 4 and 5.

When it isdesired to release the curler it is only' necessary to pivot the locking member or bale I8 away from the curl to the dotted position illustrated in Figure l, thereby releasing the strand. In yFigure 5 the curl is shown released from the bale I8 in position to permit longitudinal withdrawal of thecurler. While in the disclosed embodiment the strandV gripping member IG is formed with a `finger operating portion 22 which is biased by the spring 20, it should be understood that in some instances this structure may be eliminated. -Under such circumstances the weight of the gripping member IG is suicientto effect the initial gripping of the strancL-and the longitudinal withdrawal of the curler from the nished curl may be occasioned without the necessity of manually releasing the gripping member. In other words, the use of a spring biased or freely pivoted grippingmember is optional.

While for the purpose of illustration and description a certain preferred embodiment of the present invention has been shown, it is to be understood that the invention is not to be limited thereby since obviously such variations may `be made as are commensurate with the scope of the invention as dened in the appended claima This invention is hereby claimedas follows? 1,.
