HAIR CURLER Filed June 20, 1945 v N VEN TOR.

Patented Oct. 14, 1947 UNITED STATES PATENT QFFICE HAIR CURLER Max M. Newman, New York, N. Application June 20, 1945, SerialNo. 600,467

2 Claims.

My invention relates to haircurlers and is particularly directed to hair curlers which initially support a hair pin and which efiect an engagement between the hair pin and a curl of hair formedaround a mandrel of the curler. A hair curler of this type is shown in U. S. Patent No. 2,321,931 of June 15, 1943, to Victor M. Newman.

In curlers of this type, means should be provided on the curler tofirmly retain the hair pin so that displacement thereof is avoided while the curler elements are manipulated toform the curl.

Such'firm retention is also required when the engagement between the formed curl .and the hairpin is effected ,as otherwise the engagement may be incomplete or generally unsatisfactory. However, in attaining thiszobjective, it is dcsirable'to avoid limiting the utilityof the curler to a-specific type .or size of hair pin since a wide variety of hair pins are conventionallyusediat present.

With the foregoing in mind, an object of this invention is to increase the ,utility of such a curler by permitting the utilization of hair pins of varied sizes and :shapes Without sacrificing the required firmnessf retention referred to above. Another-object of this invention :i :to provide an efiicient hair in retaining structure which shall spread-th hair pin to anextent where its engagementwitha curl is rendered'more positive particularly in respect to .larger'curls and stray hairs.

Another ohjectof this-invention is to simplify the operatingprocedure in forming curls while producing acurler of extreme structural simplicity in which onsiderable manufacturing economies are realized.

Another-object of this invention is to provide improved means for disassociating the formed and pinned curl from'the. curler.

Other objectsof my invention will be apparent from the following description it being understood that the above general statements of the objects of my ,invention'are intended-toexplain and not-to limit itin any manner.

The support l0 and mandrel member Il may be integral and may be formed of wood, plastic, metal, etc. The support I0 also functions as a 2. handhold member and is formed with a longitudinal groove l2 in which is disposed the wire l3. The wire 13 extends the length of groove l2 and is bent over and secured to the housing It at l4.

Telescoped over the wire l3 for sliding longitudinal movement in the groove I2 is the hollow hair pin carrier 15 which also functions as a clamp, retaining a lock ofhair between itself and the mandrel member l;l in the initial step of the curling operation.

The hollow hair pin carrier i5 is bent upwardly to form a manual operating member It by which the hair pin carrier I5 can be slid over the wire l3-in its telescoping action. In order to permit such action, the hair pin carrier I 5 is formed with an. opening I! through-which the Wire I 3 enters the hollow of the hair pin carrier. The mandrel member H is formed with a longitudinally extending concavity i=8 which communicates with the slot I 2 thus providing a continuous path for the hair pin carrier l5.

The hair pin carrier [5 is tubular as seen in Fig. 4 and an arcuate section of its outer end is cut away to form a hair pin gripping tongue It). This hair pin gripping tongue includes the hump 2|] formed by'bending the tongue l9, and the downwardly biased tip 2|. Thus, the tongue I9 is substantially L-shaped by being bent in two directions, the hump 20 terminating one angle leg of the L While the tip 2-! constitutes the other angle leg. It will further be noted that the tongue is of sufficiently small size and extent. as to besubstantially confined to the closed end of thehair pin. This not only permits wider opening of the hair pin but permits almost the entire hair pin to receive the curl.v Tongue l9 cooperates With the cut edge 22 of the carrier l5 in gripping the hair pin 23. The hair pin which is of the conventional substantially U-shaped construction has its lower leg 24 gripped between the tip 2| and the cut edge 22 thus relieving the tubular portion of the carrier l5 of this function. Accordingly'the leg 24 is accorded the full diameter of the comparatively substantially wider carrier 15 as seen in Fig. 4, so that the thickness of the leg 24, or the fact that it may assume various shapes does not prevent its being received .by the carrier l5. The edge 22 bears against one .point of leg 24 and thereby urges the leg against the opposite wall of the carrier {5. Thus plastic hairpins which are ordinarily thicker than metal hairpins can be accommodated. Additional retention plus spreading of the hair pin is efiected by the tip 2| which coacts-with thehump-EU in interposing an effective wedge betweenthe 18g 24 and the leg 25 of the hair pin. It will be observed that this wedge is disposed adjacent to the junction of the legs 24 and 25 so that the angle of spread is considerably increased. The downwardly biasedtip 2| acts in opposition to the hump 20 in eflecting the wedging action. With the: foregoing construction, it may be considered that the hair pin is held at 4 places, viz., the major position of the leg 4 frictionally abutting the inner wall of the tubular carrier i5, the pressure of the cut edge 22 against the leg 24, the pressure of the tip 2| adjacent the junction of the legs 24 and 25, and the hump 20 acting in opposition thereto. The pressure at these distributed points avoids the necessity of a gripping element specifically shaped to fit the legs of the hair pin.

The mandrel H is little more than semicircular in cross section as illustrated in Fig. 5, but at the inner end thereof its sides rise, as seen in Figs. 1 and 2, so that its overall thickness at the point adjacent the wire (3 is increased accordingly, One of the purposes of this increase in thickness is to prevent the formed curl from accompanying the hair pin carrier as it recedes into the groove l2 of the support I!) since the curl will have been formed around the lesser thickness of the mandrel member H and its internal diameter will therefore be such as to prevent it riding over the portion of increased thickness.

A ring 26 is slid over to mandrel member H and, making frictional contact with the larger diameter of support 10, serves to complete the assembly of the device and to prevent the complete disassociation of the hair pin carrier l from the telescoped wire I3 as seen in Figs. 1 and The simplicity of assembly of the instant device is notable. The wire I3 is initially inserted in place. The hair pin carrier i5 is then slid in from the opposite end until the opening I! causes it to telescope the wire l3. The ring 26, which may be of metal, rubber or the like, is then slid over the mandrel member to the support where it is' frictionally retained, completing the assembly.

My invention is practiced in the following manner:

The hair pin is applied to the mandrel memher by inserting its leg 24 into the outer end of the tubular hair pin carrier l5 whereupon the above mentioned gripping elements take effect. A look of hair is then applied between the hair pin carrier I5 and the mandrel member II where it is retained due to the tendency of the carrier IE to maintain its position in the concavity l8. The device is then rotated so as to form a curl 21 around carrier l5 and mandrel member. The operating member I6 is then rearwardly actuated by'the fingers thereby retracting the carrier l5 and the hair pin. This retraction continues until the hair pin is caused to embrace the curl 27.

During this retraction, the leg 24 of the hair pin is carried toward the wire I3 due to the telescoping action of the carrier l5 and said wire. When it approaches the groove l2 it will meet the stationary wire [3 as illustrated by the dotted lines of Fig. 3 so as to prevent further movement of the hair pin. Continued retraction of the carrier [5, therefore, necessarily disassociates the hair pin from the carrier gripping elements and effectively frees the formed and pinned curl. Any tendency of the curl 21 to enter the groove I2 is resisted by the increased diameter of support l0 at that point so that the formed curl is effectively prevented from entering the support and to this extent, the increased diameter cooperates with the wire l3, each jointly serving to resist the continued movement of the respective hair pin and curl. This expedient further serves to maintain the degree of engagement between the hair pin and the curl during the ejection of the pinned curl from the curler.

During the retraction of the carrier, and after the tongue l9 leaves the closed end of the hair pin, the movement of the hair pin is confined to a straight path since it is guided by and rides in the concavity l8 of the mandrel member. Thus it cannot swerve so as to distort the curl or interfere with its proper pinning. When the carrier I5 is finally retracted, the hair pin is still in the concavity I8 and its lower leg is loosely held by the tongue l9 as illustrated in Fig. 3. This insures control of the curl at all times during its formation and pinning.

I have shown a preferred embodiment of my invention but it is obvious that numerous changes and omissions may be made without departure from its spirit.
