13 Claims.

This invention relates to hair curling devices and has particular reference to devices for rolling up the ends of hair and holding it in rolled form until it sets. I

5 Hair curling devices of this type, known generally as end-curlers", have been made in various forms, all characteristic in that they include a cylindrical body around which the hair is rolled inwardly from its ends, and a locking member 10 pivoted or otherwise attached at one end of the body and detachably connected thereto at its free end for securing the hair in rolled position while the curl sets. Various arrangements have been adopted ior detachably connecting the free end of the locking member to they body and these include spring catches which soon lose their resiliency, rubber bands which are, rapidly deteriorated by the hair treating oils, liquids and compounds used to set the hair, and other forms of connecting means which do not remain effectlve;

In accordance with the present invention, a hair curling device of the end curler type is provided which is free from the aforementioned objections in that the free end of the locking member is positively secured to the body, without the use of spring latches, rubber bands and the like, and in such a way that it cannot be detached except intentionally, and does not lose its eifectiveness.

In the new hair curling device of this invention, the lock between the body and the free end of the locking member is obtained by a relative longitudinal bodily movement between the body and the pivoted locking member, which enables locking cooperation between the corresponding free ends of the body and the locking member, preferably by the insertion of a part of the looking member in the end of the body or vice versa, so that a positive lock is made at an angle to the direction ofthe closing and opening movements of the pivoted locking member. Elastic bands and spring latches are accordingly dispensed with and a positive but readily releasable lock is provided between the locking member and the body.

More particularly, the new device of this invention comprises a tubular body having a locking member pivoted at one end to one end of the body 0 and bodily movable longitudinally with respect thereto at its pivotpoint, so that the free end of the member is releasably secured to the free end of the body. For example, the free end of the member maybe shaped for insertion into a slot 5 or other opening in the corresponding end of the body, or the free end of the member may be provided with a ring for encircling the body. The locking member is preferably urged into locking position either by a spring or by a novel resilient end portion of the locking member.

In another form of the device, in which a clamping lip is pivoted on the body for initially clamping the hair prior to the application of the locking member, the latter is carried by the lip which is bodily movable longitudinally of the body to move the locking member with it for locking and unlocking cooperation between its free end and the free end of the body in the manner described.

In another modification of the invention, the projecting ends of the hinge pin between the body and the lip is perforated for the sliding reception of the inner ends of the locking member, which is accordingly movable bodily longitudinally of the body for locking and unlocking cooperation between its free end and the free end of the body. Alternatively, only one such connection between the locking member and the pivot pin may be employed.

Also, the body may be made of metal or a nonmetallic material, such as rubber, or metal covered with rubber, and if the body is made of metal the lip may be formed integrally therewith in accordance with this invention.

It will be seen that with the present invention 'in its various iorms the objections to the usual types of end curling devices are overcome, and that a very simple, inexpensive, and a device positive in action is provided.

For a more complete understanding of the hair curling device of this invention, reference may be had to the accompanying drawing, in which Figure 1 illustrates a preferred form of the invention, in which the locking member is urged in normal locking position by the natural resiliency of its pivot end;

Figure 2 is a longitudinal cross-section therethrough, as seen along the line 2-2 01' Figure 1;

Figure 3' illustrates a modified form of the dea vice in which the free endof the locking memberv releasably encircles the corresponding end o1v the body and is urged into locking position by a spring within the body;

Figure 4 is a longitudinal section therethrough, as seen along the line 4-4 of Figure 3;

a Figure 5 illustrates a modified form of the device in which the lip is slidable longitudinally of the body and carries the locking member;

Figure 6 illustrates another modification-in which the lip and body are made of' one piece of material; and

Figure 7 is still another modification which the locking member is slidable through apertures in the pivot pin of the lip.

Referring to Figures 1 and 2 of the drawing,

numeral I0 designates a tubular bodyof metal, such as aluminum, although it may be made of rubber or other non-metallic material, or of metal coated with rubber or other non-metallic material, depending upon requirements. Also, the body may be perforated as indicated, so as to permit air circulation therethrough to facilitate drying of the hair. The lower end of the body is provided with an integral, outwardlyturned finger piece ll.

Pivoted to the body ID by means of a pivot pin I2, is a lip l3 having a semi-circular contour or a contour conforming to the contour of the outer 20 surface of the body l0, so as to partially embrace the latter. The lower end of the lip I3 is also provided with an outwardly-turned finger piece I! cooperating with the finger piece ll of body l0 and normally urged therefrom by a leaf spring points for the converging ends I! of a generally" U-shaped locking member l8, which is preferably made of resilient wire and is inwardly turned at its free end to form locking means IS. The curvature of the pivot ends II of the locking member I8 is such that they produce a cam action in openings I6, and the resiliency of the wire 4 of which the locking member l8 isformed urges these ends together, so that when the locking member is is drawn upwardly, as seen in Figure 2, the ends I! produce a self-spring action which tends to urge the member I! downwardly as seen in Figure 2. Accordingly, locking means I! is normally urged into the open free end of body I! when aligned, therewith without requiring the use of separate springs for that purpose. Also,

the device may be very simply assembled by merely inserting the ends II of the locking memher is into corresponding openings I! of the body ill, the ends I! being turned up slightly, as shown in Figure 2, to prevent them; from being withdrawn through the openings I! in use.

trated in Figures 1 and 2, the locking member II is drawnlongitudinally of the body 10 to release locking means I9 therefrom and is swung away from the body III as is indicated by the arrow in Figure 1. Finger pieces II and I4 grasped between the fingers and pressed together to separate the lip II from the body ill and the end of a strand of hair is clamped betweenthem and the strand is then rolled inwardly from its end upon the body ll. When the has been rolled on the body Ill, locking member ,I l is moved longitudinally of the body II to align the locking means I! with the open end of the body ll. The locking member is then released to permit the locking means is to snap into the open free end of the body [0 under the influence of the selfspring action afforded by the free ends II of the locking member i8. It will be observed that the sides of the locking member are drawn against 15 thebody II because of the cam action of ends l5 engaging the inner surfaces of finger pieces In utilizing the new hair curling device illusaomaso held on the body.

In the modification illustrated in Figures 3 and 4, the locking member l8a is formed at its free end with a ring 20 which is adapted to encircle the upper end of the body Ilia to serve as the locking means for the locking member I841. The

inner end of the locking member [8a is provided with a transverse bar portion 2| which is slidable longitudinally of the body la in elongated slots 22, being normally urged downwardly by means of a coil spring 23 connected at one end to the bar 2 I and at its other end to the pivot pin l2a of the lip 13s.. It will be seen that by pulling outwardly on the end 20 of the locking member l8a, this end or ring 20 may be aligned with the free end of the body Illa, so that when the locking member "a is released its spring 23 pulls it downwardly longitudinally of the body Illa, as seen in Figures 3 and 4 to cause ring 20 to encircle body Illa. and thus lock the locking member "la in position. The operation of this form of curler will be understood from the description of the operation of the form illustrated in Figures 1 and 2.

In the form of curler illustrated in Figure 5, the body lob is formed as before, but the connection between the body "lb and the lip I3!) is provided bya pin and slot combination, the pivot pin l2b passing through longitudinal slots 24 formed in opposite ends of the lip l3b. The locking'member ilb is pivoted on and is accordingly carried by the lip l3b and is formed with a transverse bar 25 at its free end which is adapted to engage in notches 2B in the free end of body lob. In utilizing this form of the curler, the hair is wrapped around the body lilb, clamped thereto by lip 13b and locked in place by aligning bar 25 of locking member l8b with notches 26 and moving the lip l3b downwardly longitudinally of the body 10b, as seen in'Figure 5, to engage the bar 25 in the notches 25. A spring 23b may be provided within the body llib for normally urging the liplib and with it the locking member 18b in a. downward direction as seen in Figure 5.

In the modified form of the curler illustrated in Figure 6, the body IOc and the lip ilc are formed of onepiece of metal, preferably aluminum, being joined by the integral connecting piece 21 which is flexible to serve as the hinge permitting the lip lie to move toward and aw y from the body liic. A compression leaf spring 22 is secured at its ends by rivets 29 to the body He and to the lip lie, so as to resiliently urge lip 13c into engagement with body Mic. The

3|, adapted to be inserted into the open free end of the body lie when the locking member lie is moved longitudinally downwardlyin slots II with the locking means II in alignment with the open free end of body I00. A spring-23c, similar to spring 22 in the form illustrated in Figure 4 may be employed for urging the lockingmember I lc normally downwardly as seen in Figure 6, although a spring is not essential, because when the rolled hair is spread out along the body llc it will lock the locking means in position.

In the form of curler illustrated in Figure 7,

the body lid and thelip lld are connected together by a pivot pin l2d the ends of which proiect to either side of thencorresponding portions of the lip lid and are each provided with a transverse perforation. Through each of these perforations slidably passes a leg 32 of the U- shaped locking member ltd. The extreme end of each leg 32 is provided with enlargement 33 which prevents it from being withdrawn from the corresponding perforationin the pivot pin l2d. The free. end of the locking member l8'd is provided with a downwardly turned means 34 for insertion into the open free end of body Ind when 10 the locking member l8d is moved downwardly as seen in Figure 7. Alternatively, only one of the legs 32 of the locking member |8d with the locking means 34 need be employed, the omitted leg of the body member being indicated by the dotted lines in Figure '7. A suitable cotter pin is inserted in the corresponding perforation in pivot pin lZd to prevent the latter from being withdrawn. In this form of locking member l8d, the locking means 34 is enlarged transversely so that it frictionally engages the inner walls of the body llld, so as to hold the locking member M11 in locked position. A spring 23d interposed between the enlargement 33 and the pin l2d normally urges the locking member l8d downwardly toward lock- 25 mg position.

It will be understood that the one-piece construction of the body We and lip l3c illustrated in Figure 6, may be employed in all forms oi'the device illustrated except the form of Figure 5,

and that the various forms of locking members I8 to l8d, inclusive, may be employed on any of the forms of body and lip combinations illustrated in the various modifications and also that the various forms of locking means it], 20, 25, 3|

and 34 may be employed with any of the various forms of locking members l8 to llld, inclusive.

It will be seen that all of the modifications of the end curler of this invention are characteristic in that the locking member is moved bodily longitudinally of the body to efiect locking and unlocking of its free end with the body and that the lock between the free end of the locking member and the body is positive and secure, so that accidental or unintended release of the locking member is impossible, it being necessary for the user to efiect positive relative longitudinal movement between the body and the locking member to release them from each other.

While certain preferred embodiments of this invention have been illustrated and described herein, it is to be understood that the invention is not limited thereby, but is susceptible of various changes of form and detail within its scope.
