HAIRPIN.

Application filed April 30, 1921. Serial No. 465,913.

To all whom it may conceive:

Be it known that I, MIoHAnL M. Mnlsnn, a citizen of the United States, residing at the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have lnvented a certain new and useful Improvement in Hairpins, of which the following is a specification.

This invention relates to hair pins and has more especial relation to that type commonly termed 1n the trade as1nv1s1ble.

These hair pins are constructed ofvery thin wire and are of very small dimensions in consequence of which they possess the ob jectionable feature of being more or less difficult of removal.

Another disadvantage is that strands of hair are sometimes pulled when feeling for the head of one of these invisible hair pins.

The leading object of the present invention is to provide a hair pin in which this objectionable feature is eliminated and in which a new and novel form of loop end or head is provided whereby while a hair pin may be more readily removed, no parts are present to impede its insertion or to catch in and lock with strands of hair to prevent its removal. A further object of the pres ent invention is to provide a hair pin of this character which may be manufactured at practically the same cost as conventional hair pins. A further object is to provide a hair pin of this character which because of its novel construction of loop end may be made of thinner wire thus adding to the invisible feature.

lVith these and other objects in View. the invention consists of the improvements hereinafter described. and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. 1, is a view in front elevation drawn to an enlarged scale of a hair pin embodying features of the invention,

Fig. 2, is a side View thereof,

Fig. 3, is a plan view thereof, and,

Fig. 4 is a. fragmentary View in side elevation of a slightly modified form of construction.

For the purpose of illustrating my invention, I have shown the accompanying drawings, several forms thereof which are present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities ofwhich my invention consists can be variously arranged and organized and that my invention is not limitedfto the precise arrangement and organization of the instrumentalities as herein shownand described. i i

In the drawings, 10 designates the prongs or tines of a hair pin which are normally spaced I, substantially. equi-distanccs apart throughout their extent and which are united at the top by a loop-end or head 11. In practice the tines of conventional hair pins have both a plane surface and a fluted surface but for illustrative purposes, I have selected unfluted tines. fit the time of manufacture of a hair pin and prior to the operation of bending the loop-end 11, I crimp or flute the thin wire employed midway of the length thereof so that the crimp-' ing is disposed laterally with respect to the length of the wire. T his crimping provides minute, conversely-inversely curved por tions which project substantially equi-distances upon each side of a line passing longitudinally through the center of the wire. When the wire is bent to hair pin configuration these inversely-conversely curved portions form upon the loop-end'or head, finger-pieces 12 by which a person may readily find and grasp a hair pin for ready application to and removal from the hair. If desired the loop-end or head may be tempered and other material than wire may be employed.

Viewed from the front, as in Fig. 1, it will be noted that the continuity of the loopend is practically the same as though th flutings were not present. This is important because the average purchaser is not disposed to buy hair pins having distorted or conspicuous loop-ends. This is particularly true of the so-called invisible hair pin and as the crimping is minute and the loopend is of the same conventional curve as a standard hair pin the invisible'idea is enhanced. i

In Fig. i, the construction is the same with the exception that the flutings are extended further toward each tine of a hair P A hair pin constructed as above described possesses the advantage of having at least one finger-grip upon opposite sides of the head whereby the pin may be readily inserted and removed from the hair. The fluting is not detrimental to the appearance of the hair pin and it costs practically no more to. manufacture than does a conventional hair pin. I am aware that numerous patents have been granted in which the loopends of hair pins are provided with formations calculated to catch, lock and otherwise fasten in the hair, but I disclaim herein any such device since I merely crimp the loopend of a conventional hair pin in order that the same may be more readily inserted and extracted.

It will now be apparent that I have devised a novel and. useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to, be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

What I claim is:

A hair pin, the tines of which are normally disposed substantially equi-distances apart throughout their extent and the loopend or head of which is syunmetrieally curved in conventional manner, said loopend or head being minutely crimped laterally with respect to the head and which erimped portion projects substantially equidistances upon opposite sidesof a line passing longitudinally through the center of the head to provide at least one finger piece upon each side of said loop-end or head.

in witness whereof, I have hereunto signed my name.

MICHAEL M. ME SEL.
