Specification of Letters Patent.
Patented Apr. 13, 1920.
Application filed April 21, 1919. Serial No. 291,471.
To aZZ whom it may concern Be it known that I, Gnonen H. BRUDER, a citizen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Hairpins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to hair-pins such as are molded from celluloid or similar material and in which means are provided for preventing accidental falling of the pins from place.
I am aware that it has been proposed to make a hair-pin, between the corrugated prongs of which there is a correspondingly corrugated tongue, but in each instance of which I know, the tongue is comparatively stiff while the prongs of the pin are resilient. The result is that when hair is wedged between the tongue and the prongs and the pin tends to work out, either or both prongs may spring away from the tongue to permit of outward movement of the bunch of hair more or less readily between the prongs and the tongue.
It is the object of the present invention to provide a construction wherein the tongue will have a lesser degree of rigidity than the prongs of the pin and the corrugations of the tongue and prongs will be so correlated that when a bunch of hair tends to move outwardly from between the tongue and one prong, it will serve to spring the tongue toward the other prong and thus reduce the throat through which the hair at that side must pass outwardly, whereby to effectively prevent such outward passage. Thus, when a large bunch of hair starts outwardly at one side or the tongue it will move the latter to grip what may be a smaller bunch of hair at the other side, in contra-distinction to the result that obtains when a bunch of hair at one side in its outward movement springs the prong away from the tongue without movement of the tongue toward the other prong of the pin.
In the drawings Figure 1 is an elevation of the pin.
Fig. 2 is a view similar to Fig. 1 and showing the tongue deflected laterally by wedging of a large bunch of hair between it and the left prong of the pin, a smaller bunch of hair being gripped by the substantial closing of the throat between the tongue and the ri ht prong oi"- the pin.
Fig. 3 is a section on line 33 of Fig. 1, to illustrate the correlative cross sectional areas of the prongs and the tongue, such as insures yielding of the tongue before the yielding of either prong.
Referring to the drawings, there is shown a hair-pin comprising the bight portion 7 and two prongs 12 each tapered slightly from the bight to its free end, to facilitate insertion in the hair of the wearer. The bight or bend may be carried into a head substantially circular in contour, and the prongs may be waved rather than straight. As shown, they include outward bows or bends 1d and 13 connected by gentle reentrant angles 10 and the upper bows connected with the head by similar angles 9, while the lower bows are continued into the free ends 11 which bow inward and then preferably diverge slightly at their tips. lowever, for the purpose of the present invention it is necessary that the prongs approach each other at intervals on their inner faces only.
From the central portion of the bight 7, between the prongs and in the same plane with them, there projects a ton ue 8 that is normally spaced from them to the sides throughout the length of the tongue.
It will be noted hat the free end of the tongue 8 is pointed and lies below the angles 10, then it gradually increases in width to a point above the angles again gradually decreases to a point short of the angles 9; thence its width again gradually increases to a point between these angles and the bight, then decreases and again increases to the bight. In other words, the tongue is shown as having two spear heads within its length, respectively standing slightly above the narr wed portions of the pin-body which occur betwee; its opposite rentrant angles. The minor cross-sectional areas of this tongue are each less than the crosssectional areas of the prongs, while the por tions of the tongue of major cross-sectional area are considerably greater, hence the tongue is more flexible or resilient than the prongs, at least at its narrowest points.
It will be noted that th tongue at its free end lies between the outward bows i l of the prongs, at which point and for some distance therefrom its cross-ectional area is llO less than that of either of the prongs. The
. tongue furthermore at other points in its length is of less cross-sectional area than either prong so that if anything be wedged between the tongue and the prong at either side, the tongue will be deflected toward the otherprong instead of the prong being deflected away from the tongue. lVith this construction it will be readily understood that whenhair is wedged between the tongue and any one of theinwardly directed parts of a prong, the tongue will be deflected toward theopposite inwardly directed part of the other prong of the pin to close or approximately close the throat between the tongue and said'other prong so as to grip any hair that may be between those portions ortointerrunt free passage of hair therebeserve to hold the pin from loosening, but the lateral displacement ofthe tongue will be arrestedby the hair that-is gripped.
What is claimed is A hair pin comprising spaced prongs and an intervenin tongue inspaced relation to the prongs, the prongs approaching the tongue at intervals and at the same points of the tongue and the tongue only at inter vals between its points wheremost closely approached by the prongs, having greater In testimony whereof I affix rny signature in the presence of two witnesses;
