Application filed May 25,

. To all whom it mag concern." i i Be it known that I, MIorrAEL J. WILLIAMS, a citizen of the United States, residing at Buffalo, county of Erie,and State of New York, have'invented a new and useful Improvement-in Hairpins, of which the fol-- lowing is'a specification. i i

This invention relates to hair pins.

' More particularly the invention relatesto the type of pins such as is shown in the patent granted to me--No. 1226836; This type of pin embodies prongs which are turnable or flexible, relatively to each other, to define loops in which strands of the hair are confined in place the pin being prevented from falling out of the hair or disengaged therefrom.

Some of the objects of the present invention are: to produce a hair pin which embodies sinuous prongs which normally cross each other, the prongs being; capable of flexing action so that upon the insertion of the pin in the hair and by imparting thereto a slight twist the prongs will reverse themselves and will in their changed. relation define a loop for the hair which has passed between the prongsthe prongs impinging against each other by virtue of the inherent flexibility of the material from which the pin is made; to produce a hair pin of the character set forth from a piece of flexible wire which is covered with a'fiexible cover-. ing such as celluloid. With these and other objects in view the invention resides in the particular formation and functions of the parts hereinafter more fully described and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of the hair pin of the present invention, and in which the prongs of the pin are shown in their normal relative positions.

Figure 2 is another elevation of the pin with the prongs as shown in Figure 1.

Figure 3 is a view similar to the view shown in Figure lbut showing the prongs reversed and as they would he were the pin applied.

Figure 4 is a view similar to Figure 2 with the prongs as shown in. Figure 3.

Figure 5 is a cross-sectional view taken on the line 5-5, Figure 1.

conjunction with eyeglasses, because a suitchain may be properly connected to the .p1n.

several views of the drawing fordetails, it will he manifest that, the pin of the present invention shown in Figures 1 to' 5 inclusive, isbent and formed from a single element to define a bight 10 from which extend prongs 11 and 12-. The prongs 11 and 12 are substantially identical in formation as regards their sinuosity. Each prong is bent or convexed inwardly just below the bight 10, bent. outwardly and slightly rebentinwardly and then outwardly thus providing a relatively long curved part. 13 which merges with a part 14 which is 'bent or curved and then rebent as at 15 to extend into a substantially straight part 16 having Referring now more particularly to the a pointed end 17. The prongs are so formed a on the bight 10 and have such relation to each other that the parts 15 of the prongs cross each other twice. It may now be well to mention thatthe element from which the pin is formed possesses the desired degree of flexibility; that the prongs in their normal relation as shown in Figures 1 and 2 have a tendency to keep slightly spaced so that strands of the hair may readily pass be tween them in the application of the pin to use. The pin is pushed into the hair the proper distance when it is twisted. The twisting, and inasmuch as the prongs are in engagement with the hair, causes the prongs to be reversed, that is to say, the prong 11 instead of lying or being disposed on one side of the other prong 12, disposed on the opposite side of the said prong 12. lnder this relation of the prongs, they have a tendency to impinge against each other due chiefly to the inherent flexibility of the element from which the pin is made, and duepartly to the formation of the pin. Under the reversed arrangement of the prongs a loop 18is formed as shown in Figure 3 and in such loop the strands of the hair are confined. When it is desired to remove the pin it is only necessary to first exert a twisting action at the bight 10 which again reverses the relation of the prongs to their normal condition thus allowing the pin to be readily withdrawn.

The element from which the pin is formed like other pins of this character is covered or coated. Pins now on the market are enamelled or japanned, While this may be i form of clone with the pin of the present invention it is one of the objects to cover the material 7 such as a steel wire with a flexible covering Such as celluloid 19, s shown in Figure 5 As shown in'Figure 6 the pin has a bight 21 which is fOrmedby-crossing the prongs. The bight 21 is therefore in the a circle to which a chain orthe like may be connected for the connection of the pin 20 to eye-glasses, exception of the bight 21 willbe made identically to the pin of the preferred form.

What is claimed is: r I 1 1.' Ahair pin bent and formed from an element possessing flexiblen'ess to provide prongs which cross each other" twice normally slightly spaced throughout the major POItlOllS'Of their length andwhich are capable of being brought-to a relation so-as to define a loop and inwhich relationthe prongs impinge each other. v

2. A hair pin bent and formed from an element possessing 'flexibleness to provide sinuous prongs which cross. each other twice normally slightly spaced throughout the The pin 20 Lwith the major portions of their lengths, and which are capable of being brought to a relation so as to define aloop, and in which relation the prongs impinge each other, the said "prongs each having a comparatively straight partbelow the lowest point at which they cross each other.

3. A hair jpin bent and formed from a composite element possessing flexibleness, to provide sinuous prongs l'LZIVIDg'CUTVQCl parts which intersect each other twice in the normal relation of the prongs but spaced to- 7 permit the passage of strands of hair therebetween, the-twisting ofthe pin when engaged in the hair causing a reversed relation of the said prongs inwhichthe said curved parts impinge each other due to the fiexibleness of the element and the formation of the pin.
