Description

HAIRPIN Filed Feb. 5,

BY my;

ATTORNE WITNESS Patented Apr. 20, 1937 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to hair pins, and its general object is to provide a hair pin of the wavy arm type commonly known as Bobbie pins, but clearly differentiates therefrom in 5 that my pin can be easily and expeditiously applied and removed, as the arms thereof are capable of being readily opened or separated and held accordingly, merely by squeezing or applying pressure at one end thereof, and when released, will return to their normal clamping poformed from a single strand of resilient material, is simple in construction, inexpensive to manufacture, and extremely eflicient in use, operation and service.

This invention'also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views,

and in which:

Figure 1 is a perspective view illustrating my pin with the parts thereof disposed in normal noted that my pin is formed from a single strand or strip of resilient metal and into a straight arm I, in the form as shown.

40 From the straight arm, the strip is shaped to provide inwardly directed converging portions 2 and 3 cooperating to present a substantially V-shaped configuration, as clearly shown in Figurel, and with the converging or inclined portion 2 spaced and disposed at an upward angle with respect to the straight arm I. From the outer end of the converging portion 3, the strip is directed inwardly and not only follows the shape of the portion 3, but is arranged in contacting engagement and cooperates therewith to provide what may be termed a handle, which for distinction is indicated by the reference numeral 4. This handle which includes the portion I has its outer end extending slightly -beyond the juncture of the portion 2 with the straight arm I, and its outer end is bent downwardly to overlap the said iuncture when the pin is disposed to open position, as will be noted upon inspection of Figure 2.

The strip from the handle v4 merges into an arm 6 which is bent transversely at equi-distantly spaced intervals throughout its length in scalloped formation to provide the wavy or serpentine confi uration.

The arm 6 terminates at its outer end flush with the outer or free end of the arm I, and the said end of the arm 6 is upwardly flared, as

shown.

While the arm I is shown as being straight, it can likewise be shaped in the same manner as the arm 6, and both of the arms may be curved in the arc of a circle from end to end to follow the curvature of the head of the wearer, or any other shape, without departing from the spirit of the invention.

From the above description and disclosure of the drawing, it will be obvious that I have provided a hair pin that not only includes a pair of cooperating arms normally disposed in gripping or clamping association, but also means whereby the arms can be readily separated or opened inapplying and removing the same with respect to the hair, and that action is accomplished merely by applying pressure or squeezing the handled end thereof, in the manner as clearly shown in Figure 2.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and. in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is:

1. A hair pin comprising a pair of clamping arms, and a V-shaped spring disposed between said arms and normally urging said arms towards each other, one of said arms being movable and having a portion thereof engaging the apex of said V-shaped spring, whereby when the legs of the V-shaped spring are pressed together the movable arm rocks on the apex of the V- shaped spring. 4

2. A hair pin comprising a stationary arm, a movable arm, and a V-shaped spring disposed between said arms and having the ends of its legs respectively secured to the arms, said movable arm having an intermediate portion thereof engaging'the apex of the V-shaped spring,

of the spring.
