HIS ATTORNEY.

Patented Nov. 7, 1950 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to hair pins and more particularly to the type commonly referred to as bobby pins.

Such hair pins are widely used in connection with hair curlers which support a hair pin while enabling a curl of hair to be formed adjacent the supported pin and thereafter producing an engagement between the pin and the formed curl. The hair pin of the instant invention is well adaptetd for such curler use as well as for the general use of pinning hair tresses.

It is an object of this invention to provide such a hair pin which not only engages a curl or tress of hair by the resilient nature of its legs or shanks as is conventional but provides an additional barrier at the end of the curl or tress of hair. In this way, the clamped hair cannot escape from the pin and, as is ver important in hair setting operations, the pin is less apt to shift around in the hair from a pre-set position. It is a further object to provide such a pin which does not interfere with the proper shape of the pinned c-url or tress in that the barrier is disposed endwise of the hair engaging portion of the pin so that it merely more or less encloses the pinned hair and does not otherwise touch it.

Other objects of my invention will be apparent from the following description, it being understood that the above general statements of the objects of my invention are intended to describe and not limit it in any manner.

Referring to the drawings:

Fig. 9 is a side View in elevation of a third modified embodiment.

Fig, 10 is a top view of the third modified embodiment.

Fig. 11 is a cross-sectional view taken along the lines llll of Fig. 9.

Referring to Figs. 1-3, the hair pin I5 comprises the flattened upper and lower legs or shanks I6 and I! which are superimposed and connected pin at the closed end l8. The hair pin is fabricated from resilient metal or plastic and the shanks are normally urged into substantially planar contact with each other as is characteristic of such hair pins or bobby pins. In Fig. 1, the hair pin is illustrated as being used in a hair curler the operation of which is described in the above patent although any similar type of hair curler may be used.

Disposed endwise of upper shank I6 is a downwardly formed bend or projection l9, which is integral therewith. As illustrated in Fig. 2, projection l9 normally descends below the shank I! but when the shanks are separated, a illustrated in Fig. l, the projection is raised so as not to interfere with the normal operation of the hair pin. In order to permit the normal descent of the projection as above described, the projection is split centrally so as to form an opening therein adapted to accommodate the lower shank l1. It is, in fact, possible to form the split projection from a normal portion of shank [6 by striking it with a die to bend it downwardly while simultaneously splitting the shank to form the slot opening, It will also be understood that the provision of the opening is not essential to the improved operation of the hair pin but the clamping action thereof is unimpaired. The opening 20 does not positively engage the projection so that it permits the free, normal descent of the projection and free ascent thereof against the inherent spring action of the shanks.

The operation of the hair pin insofar as the improvement is concerned will be essentially the same used alone or in combination with a curler. When the shanks are separated, hair ma be introduced therebetween, and when the shanks are allowed to return to their normal position, the

projection will bar the escape of the clamped hair from the so-called open end of the pin. Thus, the hair will be locked in a box-like enclosure as illustrated in the full lines of Fig. 1, the box bein formed by the two clamping shanks l6 and [7, the closed end l8 and the projection I9. Accord ingly, the hair Will be securely engaged and any tendency for the pin to shift in the hair will be minimized.

In Figs. 4 and 5, the action is identical but the lower shank 25 is shorter than the projection bearing shank 26 so as to terminate before the projection. Accordingly, no slot or opening is necessary in the projection.

In Figs. 6, '7 and 8, the projection is unslotted and the lower shank 30 is formed with an opening 3! to receive the projection 32 of the upper shank 33. The box-like enclosure for the hair is again illustrated in Fig. 6. I

In Figs. 9, 10 and 11, an embodiment is illustrated which avoids slots or openings but wherein the shanks are substantially of the same length nevertheless. The lower shank 35 is continuous as in a conventional bobby pin. The upper shank 36 is superimposed as is usual over the shank 35 until the projection portion 31 is reached. At that point, the upper shank 36 is bent outwardly and downwardly so that it descends laterally of shank 35 and below its level as illustrated in Fig. 9. Shank 36 is then bent upwardly and inwardly so as to return to its state of superimposition in respect to shank 35. Thus, shank 36 is formed with a lateral downward projection 31 which descends as required and may be formed simply from the continuous shank 36.

While there has been described what at present is considered preferred embodiments of the invention, it will be evident that many changes and modifications may be made therein without departing from its spirit. It is therefore aimed in the appended claims to cover all such changes and modifications which fall within the true spirit and scope of the invention.

I claim:

1. A hair pin of resilient material having connected and superimposed upper and lower substantially straight shanks normally urged toward each other so as to be in normal contact with each other, a projection disposed endwise of one of said shanks whereby said projection normally descends below the level of said other shank, said projection being split centrally so 'as to receive said other shank in the split center thereof whereby said shanks may meet each other while the split projection descends below said other shank.

2. A hair pin of resilient material having connected and superimposed upper and lower substantially straight shanks normally unged towards each other so as to have a normally substantially contacting relationship, and a projection member disposed endwise of one of said shanks, said projection member having at least 'a portion thereof extending laterally of said other shank so that it may descend below said other fshank'while both shanks are in said normally substantially contacting relationship.

3. A hair pin of resilient material having connected upper and lower substantially straight shanks normally. urged toward each other so as to tow be in normal contact with each other, and a projection member formed on the outer end of said upper shank, said. projection member being formed by a pair of integral and divided arms on said upper shank, said arms being rejoined at the extreme outerend of the upper shank, each of said arms at the division area thereof beingbent downward in substantially V-shaped form, said lower shank being receivable into the division area 'of said arms and being normally urged therein through the inherent resiliency of the material, whereby the V-shaped portions of the divided arms straddle and are normally below the level of said lower shank.

4. A hair pin of resilient material having connected andsuperimposed upper and lower sub: stantially straight shanks normally urged into substantially planar contact with each other, and

a projection disposed endwise of one of said shanks whereby said -projection normally descends below the level of said other shank, and said projection being" freely movable above the level of said other shank against the normal tendency of the shanks to contact one another.

5. A hair pin of resilient material having upper and lower superimposed shanks connected to each other at one end and normally urged into substantially planar contact with each other by the inherent resiliency of the material, and a projection disposed endwise of one of said shanks and extending toward the other shank whereby said projection serves as a barrier at the open end of the pin when the shanks are separated and descends below the level of the other shank when the shanks are in their normal relationship, said other shank being substantially straight, said projection being freely movable below and above the levelof the other shank, such movement above the level of the other shank being against the normal tendency of the shanks to contact one another.

6. A hair pin of resilient material having upper and lower superimposed shanks connected to each other at one end and normally urged into substantially planar contact with each other by the inherent resiliency of the material, one of said shanks being bent downwardly adjacent its free end and the other shank being substantially straight whereby the separation of said shanks produces a box-like enclosure formed by the connected end of the pin, theshanks and the downwardly bent shank portion, said boxlike enclosure being adapted to maintain a lock of hair therein, and said downwardly bent shank portion being normally movable inwardly by the inherent resiliency of the material to a position where it is substantially entirely below the level of the other shank, said downwardly bent shank portion being further freely movable outwardly from its inward position against the normal action of the resilient shanks.

7. A hair pin of resilient material having connected and superimposed upper and lower shanks normally urged into substantially planar contact with each other, a projection disposed endwise of one of said shanks whereby said projection normally descends below the level of said other shank, said other shank being straight and formed so as to permit free descent of said projection as well as free ascent thereof against the normal tendency of the shanks to approach one another.
