It is an object of thisi nventionto provide a 1 hair tastenerof the typedescribed which may be incorporated in .hair 'holders, of various types, barettesf-ribbon fasteners, and other similar "articles which. require; to be fastened -to;locks-.ot'"hair, .and which is provided to be positioned and secured,

These and other objects-of the invention, its nature, its. composition and arrangement and combination of part-siwill' be readily understood by'any one acquainted with theart to'whiehi this inventionrelates upon consultingi-the following descriptions: of :the drawings, in which Figure 1 is a general bottom view ot my improve'd -hair fastener.-

Transversely of the frame and in the inwardly difrected portions of the end portions 7 isa pin '9 whichextends across the gap-Sbetween the 55 --said:end-portions'7. The pin 9., and that p tion which bridges the gap 18 functions as a 1 pivot,.iat whichds pivotally mounted a "looking tongue 10 which is adapted to have its rounded end portion 11 rested upon the ar,cu

ate portion 6 otthe frame, when in looking position as shown in Figure 2. Re'terring again to 1 the frame 5 t-he numeral 12 indirates the points at which the end portions? are directed upwardly, and the numeral-13"l 5 indicates the-point at which the pivoted end portion of thelocking tongue is directed upwardly at an angle, and the portion between said point 13 and the contiguous extremity of the-locking leveris designated by the 1111- 70 meral 14. "On its underside the portion 1& is provided with a notch 15 which is engageable {by theflfinger nail in the unlocking operation to'be hereinafter described. In the form showninFigure' Qtheloclring T "tongue 10 is shownto 'be'longitudinally and upwardly bowed at a somewhat greater-curvatu're than the longitudinal upward bowing of the side members 5 ofthe frame. This dilierence in curvature is not seen'in Figure :8'whieh modification is better adapted to be i made in large more extended fasteners, which --will permit ofa greater degree of flexing of the locking tongue and frame when a lock of hair; is compressedtherebetween, than in the 'case asin the short or. compact form which preferably has the formation illustrated in Figure 2. Figure 3 shows the'dispositionof a'lock of hair and the relative positions of the 'locking ton'gue and the side bars of, the frame whenthe same is in locking association. Figure 9 illustrates the relative dispositionof the lock'ingtbrigu and the side memberso'f the f-farhetvheh a lock of hair-is clasped therebe- {tween by astructure made according to the modi-fication' illustrated in'Figure 8L I ltristhought to be :obvious tothose vaorquainted With-the art towhich this invention relates that in: thevform illustratedinFigure athere: uotrthernecessity ta giventhettra ne a and the locking tongue a relatively different curvature since the relatively greater length of the members permits a relatively greater flexing movement than is possible in the instance of the form illustrated in Figure 2 which comprises a relatively short and compact frame and relatively short locking tongue. In the drawings the numeral 16 designates a lock of hair. Reference to Figure 8 will disclose the specific formation of the pivoted end portion 14 of the locking tongue. It is providedlongitudinally thereof with a slot 17 in which the pin 9 engages. It is obvious that with this arrangement the locking tongue 10 may be upwardly and downwardly rocked, and relatively horizontally displaced as shown in dotted lines in Figure 2. The object of providing for a horizontal displacement is to permit the end portion 11 of the locking tongue to be brought from superposed position on the arcuate portion 6, to a position in which the said end portion 11 has certain amount of clearance from the inside of the portion 6, whereby the locking tongue is freely permitted to fall into the position shown in dotted lines in Figure 2.

In different modifications and rearrangements of the hair fastener it is advisable and may be necessary to have slotted extensions on the slot 17 formed in enlargements 18 on the portion 14 as seen in Figures 4, 6 and 7, to provide for the clearance just spoken of. In Figure 4 the extended portion of the slot takes the form of a short arcuate slot 19, and in the form shown in Figure 6 the slot extension takes the form of a slot in the form of a curve greater than a half circle as indicated by the numeral 20. In the form illustrated in Figure 7 the slot extension takes the form of a lateral offset slot 21.

It is thought to be obvious that the slot formation illustrated in Figures 4, 6 and 7 provides for positively locking the pivoted end of the locking tongue against accidental horizontal movement, and they provide the safety, non-displaceable feature of the looking tongue, in which resides one of the chief merits of this invention. It is thought to be obvious that in the form shown in Figures 4- and 6, a horizontal and upward pressure on the end portion of the locking tongue is re quired to lock the said tongue, and a reverse movement is required to unlock the same. In the form shown in Figure 7 a simple horizontal and downward or upward movement is required in the locking and unlocking operations.

In attaching the hair fastener, the lock is laid upon the locking tongue and the frame brought downwardly thereupon, and then the locking tongue is given a horizontal movement so that its end portionll may be brought to have the proper clearancefrom the portion 6 of the frame, this being necessary to freely permit the upward movement of the end portion 11 of the locking tongue, and then a reverse horizontal movement 1s given the tongue so as to be superposed upon the upper side of the portion 6 so as to lock the lock of hair as shown in Figures 9 and 3. When this is accomplished, an extra pressure may be brought to bear upon the pivoted end of the locking tongue pressing it into the oflset slot extensions illustrated in Figures 4:, 5 and 7, for securely and safely locking the locking tongue against accidental displacement as already stated.

It is to be definitely understood that I do not desire to limit the application of this 1nvention to the particular modification set forth above to illustrate the principle thereof, and any change or changes may be made in material or structure or arrangement of parts consistent with the spirit and scope of the invention.

lVhat is claimed is 1. A hair fastener of the class described comprising an elongated frame consistlng of a pair of side bars connected by a cross member at one end and having their other ends inwardly directed and in axial alignment and spaced apart, a pivot pin through said axial aligned ends and bridging said space, said side bars being longitudinally and upwardly bowed; and a longitudinally and upwardly bowed locking tongue having an angularly and upwardly directed end portion formed with a closed slot for pivotal and sliding engagement on said pin to permit pivotal and horizontal movement of tongue, said locking tongue adapted to having its other end port-ion disposed upon the cross member in looking position upon a lock of hair.

2. A hair fastener of the class described comprising an elongated frame consisting of a pair of side bars connected by a cross member at one end and having their other ends inwardly directed and in axial alignment and spaced apart, a pivot pin through said axial aligned ends and bridging said space, said side bars being longitudinally and upwardly bowed; and a longitudinally and upwardly bowed locking tongue having an angularly and upwardly directed end portion formed with a closed slot for pivotal and sliding engagement on said pin to permit pivotal and horizontal movement of tongue; said locking tongue adapted to having its other end portion disposed upon the cross member in locking position upon a lock of hair, and an extension of said closed slot formed to operate as a releasable detentfor maintaining said locking tongue normally against horizontal displacement from said position.

In testimony whereof I aflix my signature.
