they will tend to turn or twist around and in this lock themselves in the hair so that they will not fall out, and as they are pulled out of thehair they have a twisting motion in reverse. These results are accomplished by making a spiral 111 each branch of the hair pin, these spirals beingcoiled around the axis of each branch, and the spirals not being coiled around each other as'has been proposed.

In the accompanying drawings, Figure 1 is an elevation of a hair pin embodying the invention; Fig. 2 is an elevation of the same turned vertically at 90; Fig. 3 is aplan view of the position shown in Fig. 1; F ig.

4 is an elevation of a modified form ofhair.

pin in which the helixes of the arms are wound oppositely; Fig. 5 is ayfragmentary,

view of the same turned vertically at 90;

Fig. 6 is a plan view of the position shown in Fig. 4.

- Referring specifically to the drawingsflhe hair pins shown consist of two branches 6 and 7 connected at the rear end by a bend 8.v

Adjacent the bend, the twobranches'arelo'- cated in the same plane, forming what may be called or regarded as a handle portion.

Beyond this the branches diverge from said plane, as shown in Fig. 1, so that the points 9 are spaced from each other in a plane at a right angle to the plane of the handle portion. Each branch is coiled to form a helix,

as indicated at 10, and the convolution or curvature of each helix is in the form shown in Fig. l in the same direction around its respective axis, In the form shownin Fig.

4 the helices are wound oppositely. In the short hair pins the coils are rather higher pitch than those in the long hair pins.

hen the hair pin so constructed. is

pushed into the'hair the helical construction of the branches causes a twisting action which tends to crimp or twistthe hair around the branches and to draw the "branches toward each other, which has the effect ofgiving a wavy appearance to the hair and also fastens the pin in the hair so that it will not accidentally fall out, but may be withdrawn by a slight pull or special effort which will, cause the same to untwist or turn in the reverse CllIGCtlOIl, Fig. 2 illustrates a position assumed by the branches 01' the pin under a drawing action incident to placing the pin in the hair.

An important feature of this pin is that when it is pushed into the hair it does not have to be rotated by the wearer, the struc. ture being suchtha-t it rotates itself while being pushed in the hair. I am aware that the patent to Fosnight No. 811,628 shows a somewhat similar hair pin, which, however, may be forced into' the hair by proper presmay be withdrawn by rotating it, but this is objectionable and inconvenient for the operator. By means of the present construction no positive rotation is required at the hands of the operator, as all that is necessary is to force it into the hair when it will contract and rotate. itself and when so pushed in it locks itself and cannot fall out. I claim: I A hair pin having two branches and a connecting bend, the branches extending '75 sure together wit-h a slight rotation, and

from the-bend with straight portions 10- v cated in a single plane, both branches being coiled in the same direction to form helices on different axes, which axes diverge from the plane of the straight portions.

Intestimony whereof, I affix my signature in presence of two witnesses.
