Jan. 10, I F guRgH HAIRPIN Filed July 5, 1932 INVENTOR. BY LESLIE F. 51/1201 A TTORNE YS.

Patented Jan. 10, 1933 UNITED STATES LESLIE F. BURCH, OF LOS'ANGE'LES, CALIFORNIA HAIRPIN Application filed July 5,

My invention relates to hair pins and has for an object the provision of means for effectively securing same against casual loss from the hair when properly adjusted therein.

Another object of the invention is to provide a pin which is constructed from a single piece of springy material to provide effective loss preventing means to positively grip the hair when the pin is fully applied and to be quickly and conveniently disengaged therefrom by a single actuation set up therein and influenced by the effect of presssure applied to a portion of the pin by the fingers of the user.

A further object of the invention resides in a novel construction of portions of the pin with a view of providing for their mutual co-action in a manner that will be reliable and which will furnish securing surfaces of large area between which the hair is adapted to be confined.

In the accompanying drawing,

Figure 1 is a view in elevation of the pin;

Figure 2 is a view similar to Figure 1, showing the legs of the pin adjusted to their relatively separated positions, such as they would assume when inserting the pin in the hair or when removing same therefrom; and

Figure 8 is a transverse section taken on the line 33 of Figure 1.

Figure 4c is a sectional View taken on the line H of Figure 2.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my pin from a single piece of springy wire of suitable gage and of a length to furnish a pin of desired size, depending upon the particular use to which same is intended to be put. I first bend the wire medially upon itself and then spirally twist two strands thereof together to provide an intermediate section A of a leg 5, which latter I shall hereinafter refer to as the center leg of the pin, and as illustrated, the strands are extended downwardly in relative parallelism from said section A and connected together by a return bend or bight 6. Above the section 4, the strands which form said center leg are extended in an upward direction to pro- 1932. Serial No. 620,959.

vide relatively springy branches 6" 6 These branches 6.6 arejnow continued to provide somewhat elongated horizontally disposed actuating loops 7- 7, and the wire is then furthercontinued to form legs 99, which latter are suitably crimped or fluted to coact with the similar'surfaces of the leg 5 and assist in the functioning thereof as a means to securely hold the pin against accidental loss from the hair when the pin is applied. H

The legs 9-9 are preferably the samein length as the aforementioned center leg 5. Now, it will be noted that because of the provision of the aforementioned branches 6 .6 the center leg 5 and the legs 9 9 normally tend to assume a position in substantial parallelism with respect to each other and that in consequence thereof the respective legs. will securely impinge against the hair which occupies the space between the said legs. When the loops 77 are pressed upon, when gripped between the fingers, the pressure being exerted in the directions of the arrows aa, the legs 99 will be effectively moved tothe positions shown in Figure 2, at which time the pin can be freely inserted in or removed from the hair.

lThe branches (l -6 occupy positions one in front of the other and by virtue of the twisted section A of said center leg 5, considerable resiliency is established from the point A to the point B, at which latter these branches join the loops 7'? so that considerable pressure. of the fingers must be applied against the loops before the branches (S -'6" can be moved to angular positions with respect to one another. It is because thereof that a high degree of resiliency is set up in the legs 9-9, which serves effectively to securely hold these legs tightly pressed against mer, the said means consisting of loops, each having a branch extending into the center leg and a branch extending into an adjacent side leg.

2. A hair pin constructed from a single piece of springy material and provided with a center leg having wave-like undulations, and a pair of similar side legs between which the center leg is interposed, the center leg consisting of two portions of said material spirally twisted together and the said side legs each consisting of a single portion of said material, one end of which is continued into one of the portions of said center leg, through an elongated angularly disposed loop at one end of the pin.

3. A hair pin formed from a single piece of springy wire and provided with a center leg and a pair of side legs in normal parallelism therewith and connected to said center leg by loops, the angle of each of which relative to a line drawn longitudinally through said center leg is such as will allow the two legs to be separated relatively when pressure of the finger is exerted against said loops.

4. A hair pin provided with a central leg and a pair of side legs between which the former is interposed the central leg consist- 1 ing of tow strands of wire intertwisted together for a portion of their length and provided with free springy portions forming continuations of the intertwisted strands and terminating in manipulating loops, the said loops each having a part thereof continued intoan adjacent one of the said side legs, whereby when pressure of the fingers is applied against the loops and distributed toward the long axis of the pin, the side legs will be moved relatively and away from said central leg against the normal tendency of said springy portions.

5. A hair pin formed with a center leg and a pair of side legs between which latter the :center leg is interposed, and means including interconnecting springy portions joining the center leg with the respective side legs and having branches adapted to be grasped between the fingers of the hand and ;pressed upon thereby so as to move the said side legs relative to the center leg.
