HAIR CURLER Filed June 26, 1941 INVENTOR ATTORNEY Patented July 11, 1944 UNITED STATES 'E ATENT OFFICE 12 Claims.

My invention relates .to an improvement in hair curlers, wherein it is desired to provide a curler which is simple in construction and inexpensively formed.

:Many different designs. of hair curlers have previously been constructed. Some of these curlers are constructed with tubular elements having a clamping member to hold the hair against the tubular element. While these previous constructions have proven satisfactory in most respects, they are disadvantageous for two reasons. In the first place, the tubular elements are costly to construct, and must preferably be formed of light weight material which is sometimes difiilcult to obtain. In the second place, the tubular bodies are extremely apt to be uncomfortable to the wearer if they are worn overnight.

a It is the object of the present invention to overcome the previous difilculties experienced with hair curlers of the same general type, and to provide a curler which may be inexpensively constructed and formed of material which is readily available. It is further theobject of the invention to provide a curler which is formed of rounded parts which are not apt to injure the wearer even if the curlers are worn at night.

It is a feature of my invention to provide a curler which is formed of a substantially U- shaped piece of wire or strip material having a closed end and opposed open ends. This substantially U-shaped strip of material may be of one piece, or of two pieces secured together and is designed to engage the ends of locks of hair therebetween. The hair which is engaged between the sides of the U-shaped element is clamped under the spring tension of the U- shaped element itself, which obviates the necessity for a separate clamping element of the type commonly used in the past to clamp the ends of the strands of hair.

It is a feature of my invention to provide in combination with a spring clamping member for clamping the ends of strands of hair, a loop orthe like, which engages over the hair wound aboutthe clamping element so as to hold the curler in place. This clamping loop or element is pivotally secured adjacent the closed end of the clamping element and swings over the open end thereof to lock in this position. When swung over the end of the clamping element the Wire loop is held in place with respect to the clamping element so that the hair wound thereupon cannot become unwound therefrom.

Aieature of my invention resides in the fact that the clamping element itself forms the clamp for engaging the ends of the strands of hair, thereby obviating the necessity of a separate clamping member and spring for urging the clamping member against the curler body. Not only does this simplify and cheapen the cost of manufacture, but also it makes the curler easier to insert and remove, as less parts must be operated in order to properly position the curler in the hair.

A further feature of my invention lies in the fact that means may be provided for spreading the ends of the clamping member if it is so desired. As a result, the opposite sides of the clamping element may be easily engaged by the fingers and spread apart for insertion, the natural spring of the material holding these clamping members together to clamp the ends of the strands of hair therebetween, when finger pressure tending to spread the clamping members apart is released.

A further feature of my invention resides in the provision of a rivet or grommet, when such is required, which turns in combination with the locking loop of wire. In order to maintain the proper pivotal engagement between the wire locking loop and the clamping body of the curler, the rivet or grommet is so formed as to rotate with the locking loop, thereby preventing any danger of injury to the locking loop, or any tendency for the locking loop to resist pivotal movement when being swung into or out of place.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.

Figure 11 is a side elevation view of a modified form of curler.

Figure 12 is a top plan view of the curler illustrated in Figure 11.

a closed loop I2 which forms a bearing for the pivot of the curler. A pair of parallel arms I3 extend outwardly from the loo I2 and diverge outwardly toward their extremities I4. The diverging ends I4 permit hair to enter between the parallel arms I3 and to be clamped. firmly therebetween. This provides an anchor for the ends of the strands of hair which are then wound about the clamping body I0.

The wire loop II is preferably provided with a central closed end I5 and a pair of circular loop ends I6 thereupon. The circular loop ends I6 are designed to lie on opposite sides of the clamping body 100p I2 and to be held in this position by a rivet or grommet I! which forms a pivot for the two'elements I6 and II. The spring arms I9 of the locking loop II, preferably extend parallel at 20 for a short distance closely adjacent the pivot I1 and then are outwardly from the clamping body Ill to overlie the hair wound about the clamping body Ill. The arms I9 arc inwardly near the closed end I5, forming a pair of opposite projecting points 2I which are spaced apart a distance less than the diameter of the arms I3 of the clamping body Ill. Between these points 2I and the loop end I5 of the locking loop II, the arms I9 curve outwardly to form a finger engaging end by means of which the looking loop may be pivoted into and out of locking position.

In operation, the ends of the strands of hair are inserted between the diverging ends I4 of the arms I3, and the curler is urged into clamping position much in the manner in which a clothes pin is inserted into place. When the ends of the strands of hair have been clamped, the curler is rotated to wind the hair about the clamping body I6. During this operation, the locking loop I I is swung into the position indicated in dotted outline in Figure 1 of the drawing.

When the hair has been wound about the curler body, the locking loop I I is swung through substantially 180 degrees, the inwardly projecting points 2I engaging against one of the arms I3 and being spread by contact with the clamping body. When the loop II has been swung into the position indicated in Figure l of the drawing, it will remain in place until manually removed, because in order to pivot out of this position the locking loop llmust spread adjacent'the points 2I under spring tension This spring tension, necessary to spread the opposite arms III of the loop II, is just sufiicient to p fiovent accidental opening of the locking loop without making the curler difficult to operate.

As illustrated in Figure 4 of the drawing, the pivot I1 is preferably in the form of a grommet having a substantially cylindrical wall 22, about which the loops I6 and I2 are engaged. End flanges 23 firmly clamp the circular loops I6 and I2 in place. In preferred form notches 24 are cut in the flanges 23 to engage on opposite sides of the parallel portions of the loop II so as to cause rotation of the grommet I! in unison with the locking loop II. As the entire locking loop pivots in unison with the grommet, rotation of either of the loops I6 is not hindered by friction on both sides of the loop tending to bend the relatively thin wire loop I6 out of shape.

In Figuers 5 through 10 of the drawing, I disclose the curler B, which is slightly difierent in construction from that previously described. The curler B is preferably formed from an elongated fiat strip of material which is centrally folded at 25 to provide opposed arms 26. The arms 26 may be integral or may be formed of two parts connected together at thefold 25. In preferred form the fold 25 is enlarged to form a barrel 28 for journaling the end of a wire locking loop 21. The ends of the loop 21 may be inserted in the hollow journal 28 and may pivot with respect to the .curler body.

The curler body is comprised, as has been stated, of arms 26. These arms 26 are bent to provide parallel portions 29 adjacent the journal 28 and are then formed to provide outwardly arcuated loops 36. The loops 30 are arcuated outwardly a sufiicient distance to permit the fingers to engage therebetween to spread these loop portions apart as best seen in Figure 8 of the drawing. The edges of the arcuated .portions 36 are rolled inwardly soas to provide a smooth folded surface forrengagement of the fingers. By grasping the curler, as illustrated in Figure '7 of the drawing, an inward pressure of the finger and thumb will spread the arms 26 apart to'permit hair to enter-between the arms 26. With the ends of the strands of hair between the arms 26 the pressure is released, allowing the arms to clamp together.

The arms 26 beyond the arcuated portions 36 continue into parallel portions 3!, which are preferably slightly channel-shaped, as best illustrated in Figure 9 of the drawing. This curving of the parallel portions 3I of the arms tends to stiflen the arms and also to continue the tendency for the hair to curl around the curler body. The extreme ends 32 of the arms 26 are fiat and are spaced slightly apart, as best illustrated in Figures 5 and 10 of the drawing.

The locking loop 21 is arcuated outwardly at 33 away from the arms 26 and near the free ends,

32. The locking loop is bowed inwardly to provide projecting portions 34 which are normally spaced closer together than the width of the arms 26. Thus the locking loop engages between the ends 32 of the curler body, thus holding the locking loop 2'! in looking position; The locking loop 33 is preferably provided with a closed end 35 projecting beyond the ends of the arms 26 to permit swinging of the loop.

In operation the curler B is grasped as illustrated in Figure 7 of the drawing, the armsf26 being spread by pressure of the finger andthumb.

The ends of the strands of hair are'then clamped. between the arms 26' which hold the strands of hair while the strandsare wrapped. about the aboutthe clamping body, the loop 21 is-swung into locking position, at which time the projecting points 34 engage between the ends 'of the arms 26. The locking loop is held in place until it is manually pivoted out of locking position.

In Figures 11 and 12 of the drawing, I disclose another form of my invention, which is similar in construction to that which has just been described. In the curler C, illustrated in Figures 11 and 12, the curler is formed of a strip of material which is folded at 35 to provide two parallel arms 31. The arms 31 are essentially flat and parallel at portions 39 adjacent the fold 3t, and are then outwardly arcuatedto form out wardly bulging portions 40 which provide finger engaging means. The arcuated portions 40 merge into clamping-portionsfil, which are preferably somewhat channel-shaped in cross section,'as indicated in Figure 9;

- This-channel shape of the arms 31 stiffens the arms'and assists the natural tendency for the hair ends to curl. As in the case of the curler B, the arms 37 are free to flex apart between the finger engaging portions and the central fold, as the portions intermediate the finger engaging portions and the central fold are fiat and the remaining portions of the curler body are preferably provided with rolled edges.

As noted in Figures 11 and 12 of the drawing, the finger engaging portions do are provided with rolled edges 42 which are bent in much the manner indicated in Figure 8 of the drawing. Thus the finger is not injured by the relatively sharp edges of the curled body.

A pair of elongated slots 43 are cut in the arms 37 near the extreme free edges thereof, A wire loop 44 is provided with inturned ends 45 which engage in apertures 4% in the flat portions 39 of the curler body. The wire loop 44 is provided with substantially parallel portions 3? adjacent the inturned ends 45 and then bows outwardly to extend over the finger engaging portions 49. The loop 44 arcs inwardly near the free ends of the arms 31 and is provided with projecting points 49 which engage into the slots 43. The loop 44 is preferably closed at 56 so as to provide a means of swinging the loop into or out of locking position. In this case, however, as well as in the previously described constructions, the loop 44 may be closed at its pivot end and open at its outer end.

In operation the curler C is identical with the curler B. In other words, the entire construction is identical to that of the curler B, with the exception that the loop 44 of the curler C is positioned to pivot about an axis perpendicular to the fiat parallel portions 39 of the arms 31, while in the curler B the loop 2! is pivoted on an axis parallel to the plane of the parallel portions 29 of the arms 26.
