STATE CHARLES ALBERT DIES, OF CHICAGQ, ILLINOIS.

HAIRIPIN.

To all whom it may concem.

Be it known that I, CHARLES A. DIES, a citizen of the United States, residm at Chicago, in the county of Cool; and of Illinois, have invented certam new and useful Improvements in Hair-pins, of which the following is a description.

My invention relates to that class of devices used in dressing ladies hair and commonly known as hair pins.

The object of my invention is to provlde a devic of the kind described whlch when inserted in the hair will retain its position until it is desred to remove it and also one by means of which the hair may be secured a and firmly retained in its desired position and so obviate the inconvenience and annoyance caused by the falling out of the pins and consequent derangement of the hair.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and descrlbed, and more particularly pointed out in the claims.

In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts:

Figure 1 is a side elevation of my improved hair pin.

Fig. 2 is an edge elevation of the same. Fig. 3 is a section taken substantially on line 3-3 of Fig. 1.

Fig. 4 is a side elevation of a slightly modified form of my improvement.

Fig. 5 is a similar view of another modified form.

In the form shown-in Figs. 1, 2 and 3 my improvement comprises a member 1 formed of wire or other suitable material, bent substantially at its center to form a U shaped pin with arms of substantially uniform length. As shown a portion 2 of the arms at the closed end of the pin are substantially parallel and lie in a common plane while the next adjacent portion of the arms are bent to form a helix about a common center 3 and diverge from each other toward the free ends of the arms to the point 5, the next adjacent portion 6 of the arms while continuing the helical curve about the I center line 3 converge -regularly toward the free ends of the arms whil the end portion 8 of the arms still continuing the helical curve again diverges to the end of the arm so that in twisting the pin into the hair the Specification of Letters Patent.

tate

hair tends to force the free en of the arms apart so that the parts 6 will assume a position substantially parallel to each other when in service and resiliently engage the hair positioned between the arms to hold the pin and the engaged hair in position.

When thus constructed it is obviously desirable that the bending action when inservice should occur as far as possible in-the parts 4 of the pin'which being of'considerable length permits a free resilient movement of the parts 6 and 8 without permanently distorting the pin. To insure this action the member 1 is preferably flattened as shown near the closed end of the pin sub- Patented May 10, 1921. Application filed June 28, 1916. Serial No. 105.472.

2 of the arms a slightly tapering form laterally as shown.

In the preferred construction also a laterally projectlng bead 9 is provided on both sides of the pin at the outer margin of its closed end preferably extending entirel across the end of the pin thus further still ening this portion of the member and provide a convenient grip for the fingers in inserting or removing the pin from the hair. In this form also the pitch of the helical curve is reduced slightly toward the; free end of the arms to still further increase the holding efi'ect of the pin and prevent its disengagement from the hair when in service.

. i In the form shown in Fig. 4 my improved hair pin is formed in all respects substantially the sameas shown in Figs. 1 to 3'with the single exception that in this form the section 11 of the arms corresponding to the section 6 in the form hereinbefore described the arms are substantially parallel instead of converging. In this form when in service the arms are slightly divergent or spread toward their free ends and while forming an excellent device for securing the hair in position does not retain its place in the hair as satisfactorily as the form hereinbefore described.

In the formshown in Fig. 5 my improved of the helical curve in the form shown in Fig. 5 remains constant throughout its entire length instead of decreasing toward the free end of the arms. The general utility and holding power of this form of my device is very nearly, if not uite as satlsfactor as the form shown in B igs, 1 to 3.

Iiaving thus described my improvement it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact formor construction shown.

What I claim as new and desire to secure by Letters Patent is:

1. A hair-pin comprising a U shaped memher having arms of substantially uniform length, each curved helically about a common central axis, said arms gradually approaching each other to a point adjacent their free ends and thereafter diverging slightly to their extremities, said member being flattened at the closed end of said pin parallel to the common plane ofsaid arms and having a laterally projecting bead on both sides of the pin at the outer margin thereof.

2. A hair-pin comprising a U shaped member having arms of substantially uniform length, each curved helically about a commoncentral axis, said arms gradually approaching each other to a point adjacent their free ends and thereafter diverging slightly to their extremities, said member being flattened near the closed end of said pin parallel to'the common plane of said arms and having a laterally projecting bead at the outer margin of the closed end of the pm.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
