6 Claims. (01. 13244) M y invention relates to hair curlers and some.
of its objects. are to makethe curling operation easier, quickerand more accurate. I
.Qther objects aretoprovide ahair curlerthat can be conveniently held and operated in a posh.
tion where the curling corerotates about an axis substantially perpendicular to the scalp of. theperson whose hairis being. curled, to operate the rotation of, the curling corebya movement substantially parallel to the surface ofthis scalp, and.
thereby to make the formation of .curlsadiar.
cent .to thi surface more convenient and accurate.
Eurtherobjects are to. provide a hair curler with a shafthaving two oppositejends, each of which canbe co-axially connected with thecurl-ingcore, thereby to provide. optional. use. ,of either shaft endHthereby to make possible the rotationot the core in eitherof thetwoopposite .turning direc tions, and to hold and operate the curler in. each of these two cases in substantially the same convenient-and efficient manner. I Stillother objects'are to secure the curled condition of the hair before the. curl is removed from the core by means present in the hair curler,
thereby to avoid thepicking up of hair pins while the curl is not finally secured, thereby to avoid damage to the shape of the formed curl, and to accelerate theformation of one curl and of a seriesof'curls.
Still further objects-are tofacilitate the -re-- move-l of-the curls from the-curling; core insecured condition and in the correct position of the curls parallel to the head surface, to increasethe radial tension of thesecured curls, and thereby to make well shaped curls. I
Still otherpbjects areato. attain these results with. simple and inexpensive. means; and .to. provid a hair curler, that. .can be easily assembled and handled and that operates reliably.
Stillot er objects and -,40 advantages will appear:
from the following description of-an exemplifying.- embodiment of my invention, from the appended 1 claims and from the accompanying drawing in which: 7

Fig. 7 shows a bottom view of the member sh0wninFig.-6.:
Referring to the .drawing,-. numeral-I indicates a frame or housing of elongated shape. A smaller frame 4 maybe positioned in'and aflixedto the 1 frame I These frames support a mechanism which comprises a rack or toothed rod! passing.
'slidably through a-slot in an end walls of the frame I and through similar slots of the frame-4. The outer end of the rod 1 isprovided with-a button 9. whereby .therack 7 can be -pushed.inwardly*by---= compressing the button 9 and the rim I I between fingers of one hand. r
A shaft I2 passes'rotatably-through thehous ing I- and'through a wall the'housingrland of the rod I. Bothouterends of the shaft I2 are adapted for co-axial connec 'w tion with a curling core-that will be described. later. For example, a slotted cone I4 is afilxed'to.
each of these shaft ends and is provided withar bore I5 for the passage of a.connectingrpin lfizz The housing I- contains a gear or drivin me hs-ul afiismadapted to establish a driving connection 2 between the rack 1 and the shaft IZ. Thi mech- .w'
II-engaging. a
of the frameshfA-is another pinion 23 {Ki I Preferably the wheel 22 engagesltheminion'zn only when. the rack! is pushedinwardlyss-Ai spring 24 hasan-end attached to a hook-shaped projection; 25 of the.-rack;and.has another end w \projection 26 nf.:the.; wall. .8. The. tension .of the spring =24 :pullssthe rack. into the. shown position: in which a projec-ll 3 attached to .a' hook-shaped tion 21 of the inner rack end contacts the frame 4 and stops further contraction of the spring.
The wall 8 has a projectingrim- II:
I3 .of the frame: 4 inflax direction crossing I the longitudinalndirection of "I9 Which.- passes freq-:3 the housing :la and the same shaft 19.1..
When the rack is pushed inwardly against the tension of the spring 24, the teeth I"! move the pinion 18 together with the shaft 19 and the Wheel 22 toward the pinion 23 until the wheel 22 and the pinion 23 engage each other. Further movement of the rack in the same direction rotates the inion IS, the wheel 22 and the pinion 23. When the pressure on the bottom 9 which was used for pushing the rack ceases, the spring moves the rack back into the shown position, disengaging the wheel 22 from the pinion 23.
During this operation, the shaft I9 moves guidedly in a short slot 28 of the wall l3 and in a similar parallel slot of the housing I between the ends of thes slots.
A curling core 29 of generally cylindrical shape is co-axially afiixed to the shaft 12. Preferably this element is adapted for optional attachment to either one of the two shaft ends. Hence the element may be rotated by the rack either in g clockwise direction, seen from its free end, in counter-clockwise direction.
The core 29 may be aifixed or coupled to the shaft l2 by means of a flat plate 31 which forms an axial projection of this element and fits the slot of either cone 14. The plate 3| has a crossing bore 2| which, in coupled position, forms a continuation of the bores l of the cone [4. The pin 16 passes through the bores I5 and 2| and thereby secures the plate 3| to the cone l4. By withdrawal of the pin 16, the element '29 may be detached from one shaft end whereupon the element may be attached to the other shaft end.
The core 29 is hollow and its cylindrical inner space 32 extends as far as the free end of the core. This free end is open. The core is provided with clamping means for the attachment of a strand of hair. For example, a resilient arm 33 has one end affixed to the outside of the core 29 and extends in the longitudinal direction of the core toward another end positioned near the open end of the core whereby the arm 33 together with the core forms a clamp adapted for gripping a strand of hair and for releasing this strand when the latter is Withdrawn beyond the free end of the core.
The core 29 has two longitudinal slots 34 which extend from the open end, are longer than the arm 33 and are preferably positioned diametrically opposite to each other. Each of these slots serves for the passage of one leg of a hair pin 35, the remaining part of which is positioned in the core and is slidably guided therein in axial direction of the core. Preferably there are two pins 35 with heads which are rotatably connected. These pins may be parts of a member 36 which has two side plates 31 connected by a pivot axle 38 passing through bores of the two pins 35. A little bar 39 connects the plates 31 and is so positioned that the bar forms a stop for the mutual rotation of the pins whereby the latter are prevented from approaching each other more than shown in dotted lines in Fig. 6 when the pins are turned in the direction of the arrows 41. Other stops 42 may connect the plates 31 at the other side of the pins and may prevent rotation in the opposite direction beyond the position shown in full lines in Fig. 6.
Each pin 35 has two resilient legs or prongs 43 and 44. The leg 43 has a thickness smaller or at least not larger than the width of the slot 34, measured in axial direction of the axle 38, whereby this leg can pass through and slide along this slot. The leg 44 is thicker, measured in 4 the same direction, and cannot pass through this slot. The leg 44 may be slightly shorter than the leg 43.
A plurality of members 36 is preferably used. These members are arranged in a row extending in the longitudinal direction of the core. For example, Fig. 5 shows two members 35, one positioned before the other, seen from the open end of the core. The legs 43 of each member, when inserted in the core as shown in Fig. 5, extend through the slots 34 beyond the lateral surface of the core in obliquely spreading directions. The legs 44 spread in the same directions, but are confined within the core because of their larger thickness. These legs contact the inner side of the cores wall and are slightly bent toward each other by the resistance of this wall. The inserted members 36 can be pushed along and out of the core while their legs 44 slide along the wall of the core.
In order to facilitate this pushing operation, a pushing member 45 is positioned slidably within the core. The member 45 may have a cylindrical shape and a projection 46 reaching through a longitudinal slot 41 of the core which slot ends at a short distance from the cores open end.
The above described hair curler operates as follows:
After one or several members 36 are inserted in the core 29 as shown in Fig. 5, a strand of hair is clamped under the arm 33. The curler is preferably held in a position where the longitudinal direction of the curling core is perpendicular to the surface of the scalp. Then, the core is rotated by pressing the button 9 whereby a curl is wound closely around the core. Then, the pushing member 45 is moved toward the open end of the core until the first member 36 emerges from the core. During this movement, the tips of the legs 43 move outside of the formed curl, and the tips of the legs 44 move inside of the same whereby the emerging pins 35 grip the curl from two sides and hold the curl in wound condition. After the first member 36 has been so applied to a curl, this member is straightened by turning its pins into the position shown in Fig. 6 in full lines.
Then, the remaining members 36 and the member 45 are pushed back from the open core end, and the curl forming and securing operation is repeated with the next member 36 being active. In this manner a series of curls may be made accurately and uniformly in quick succession.
I desire it understood that my invention is not confined to the particular embodiment shown and described, the same being merely illustrative, and that my invention may be carried out in other ways within the scope of the appended claims without departing from the spirit of my invention, as it is obvious that the particular embodiment shown and described is only one of the many that may be employed to attain the objects of my invention.
