WILLIAM EDWARDS, SAN DIEGO, CALlFORNIA.

HAIR-PIN;

Specification of Letters Patent.

Application filed October 23, 1918. 'Serial No. 127,266.

To all 'whom it may concern: I

Be it known that 1,.WILLLAM T. EDWARDS,

a citizen of the United States of America; residing at Diego and advantages of the in-' vention will be set forth in the detailed de scription which now follows:

a The figure shown in the accompanying drawing is a front face view of my improved'hair pin. I

- Referring to the drawing, it will be seen pin is made of a single piece that the bight portion of this wire'is bentlupon itself to form a central prong 5 above which the wire is outwardly flared and lies at an acute angle to the medianline of the hair pin forming the por-' tions 6. The portions 6 are continued to form inwardly directed shoulders -7 and above these shoulders the twoparts of the wire are twisted into engagement with each other at 8 to form a stiffening and reinforcing -memberwhich prevents separation of the outer sides of the hair in. Above the twisted portion 8 the wire 18 bent outwardly 'aarddownwardly in opposite directions at 9 and 10 and is then bent outwardly at .11 and inwardly at 12 to form portions conforming in their general outline to the outer sides of'the flaring portions 6 and shoulders 7 and is then extended downwardly for a considerable distance toform the side prongs 13 and 14.

From the foregoing description it will be seen that I have provided a three prong hair. pin with the resultant advantage that more strands of hair may be engaged thereby than with the two prong'hair pin so that the hair is more effectually held in the desired position. In addition. the central prong 5 depending bet-ween the prongs 13 311K114 forms two entrance channels 15 and .16 throughwhich the hair passes. The fiar ing portions 6 acting in conjunction with the portion 1-2 constitute restricted passages '17 and 18 into which the hai'ris more or less compressed as the pin is pushed into'plac'e so that when the hair finally reaches the upper portions of the assages 17 and 18, the tendency to expan causes it to move behind the shoulders 7 and since these shoulders 7 lie at an obtuse angle to the median. line of the hair pin, it follows that the hair 'pi'n' will not become readily disengaged from Patented Feb. 2c, 1917.

the hair but that, upon the contrary, more force is required to remove the hair pin than is required to place the hair pin in position and considerably more pull is necessary to remove the hair pin than is necessary to remove a hair pin of the ordinary type.

Vhile the 'elements shown and described are welladapted to serve the purposes for which they are intended it is to be understood that" the invention is not limited to the precise construction set forth but in 'cludes within its purview"whatever changes as fairly come within the spirit ofthe ap-.

pended claimsv -Having described my invention what I claim is 1. A hair pin made from a single piece of wire, the opposite ends of which constitute prongs and the bight portion of which is bent to form a central prong then bent to.

form outwardly divergent portions which lie at an acute angle to the median line of the hair pin, then bent inwardly to form shoulders that lie at an obtuse angle to the median line of the hair pin and are then continued to the first named prongs, that portion of thehair pin at the juncture of the divergent portions and theshoulders lying in spaced relation to the first named prongs and all of the portions of the hair pin lying in substantially the same transverse plane.

25A hair pin made from a single piece of wire, the opposite ends of which constitute -prongs and the biglft portion of which is bent to form a central prong then bent to form outwardly divergent portions which lie at an acnteangle to the median line of the hair pin, then bent inwardly to form shoulders that lie at an obtuse angle to the median line of the hair pin and are then continued to' the first named prongs, said first named prongs comprising outwardly bent portions which conform to the outline of the divergent portions and the shoulders and lie in spaced relation thereto. all of the portions of the hair pin lying in substantially the same transverse plane.

3. A hair pin made from a single piece of wire and bent at its bight portion to form a central'prong, then bent to form outwardly divergent portions which lie at'an acute angle to the median hne of the hair. pin, then bent lnwardly to form shoulders.

that lie at an obtuse angle to the median line of the hair pin, then bent to-twisted formation and then bent outwardly and downwardly to form side prongs, all of the portions of the hair pin lying in substantlallythe same transverse plane. 4. A hair pin made of a single plece of.

' wire and bent at its bight portion to form wardly to form side prongs, said side prongs 4 comprising bent portions which con form to the outline of the divergent portions and the shoulders, all of the portions of the hair 2 'pin lying in-substantial'ly thesame transverse plane. 1

5. 3; hair pin made. of a single piece of wire and bent to form side prongs and a central prong, said side prongs and said central prong being bent to such shape as to constitute receiving passages, constricted passages above said receiving passages and abrupt shoulders at the upper ends of the constricted passages, all of the portions of 3 the hair pin lying in substantially the same transverse plane.

In testimony whereof I aflix my signature in presence of two witnesses.
