lAmilioation Med June 24, 1926. Serial No. 118,168.

This invention relates generally to devices intended to be used in dressing the hair.

lMany kinds of pins have been roposed for use with short or bobbed hair. ne type of pin particularly adapted4 for this purpose comprises merely a short strip of spring metal doubled upon itself to form a pair of parallel branches which are retained in close contact by the natural resilience of the strip. These pins however have not been entirely satisfactory since the branches are difficult to spread with the'fingers in spite of the use of odset and divergent ends.'

It is an object of this invention to devise a hair in in which the twin .branches may be readiily spread with the fingers.

A further Vobject of this invention will appear from the following description in which we have set forth the preferred einbodiineiit of our invention. It is to be understood that `the scope of the invention is to be determined from the present claims and the state ofthe prior art.

Referring to the drawings:

Fig. 1 is a side view of the hair pin incorporating the principles of this invention.

Fig. 2 is a plan view of the pin shown in 1. at igs. 3-6 are views similar to Fig. 1 showingseveral modifications of the invention.

heinvention com rises generally a single spring strip whic is bent to form contacting branches which may be spread by applying pressure at one end of the pin. Referring to the drawings, there is shown,a hair pin constructed of a single relatively at spring strip 10 of metal or other suitable material Which is doubled upon itself to et. form a looped end 11 at a pair of Contactin branches 12 and 13 which extend paralle and are retained in close contact by the natural resilience of the strip. In prior hair pins of this type it has een necessary te either diverge the end of" the branches 12 and 13 orto make one of the branches longer than the otherin order to facilitate spreading of the branches by the ngers. In this invention the strip between the looped end and the branches is formed in such a manner that by applying pressure the ends of the branches 12 and 13 may be readily spread.

Thus in that form of the invention shown in Figs. 1 and 2 the strip between the looped end 11 and the contacting branches is formed 55 in such a manner as to provide spaced ingerhold portions 14 and 15 which comprise a` substantial artof the length of the pin. These finger old portions converge as at 16 and 17 to mer e with the branches '12 and 60 13. Upon app ying pressure to the fingerholdfportions 14 and 15 it isobvious that' the point 18 at which the convergin portions 16 and 17 merge with the brano es 12 and 13, will form in effect a fulcrum about 65 which the branches 12 and 13 will rotate, thus causin the branches to be( spread as shown in otted lines of Fig. 1. After spreading them a certain amount in this manner it is obvious that the operator may 79 grasp the branches with the free hand to spread them a further amount if necessary.

'llhe modification shown in Fi 3 issome-i what similar to that describe above but differs in that the ingerhold, portions 315 extend inalinement` with branch l13. The operation of this pin however isy identical to the pin shown in Figs. 1 and 2. lin the pin shown ,in Fig. 4 the fingerhold portion i414 and 415 have been clamped closer togetherto limit their inward movement so that the elastic limit of the metal strip will not be exceeded. ln this case the looped end 411 has been formed to extend beyond the lfingerhfold ortions in order to prevent '85 the pin from slipping from the lingers; The iingerhold portions need not be made straight but may be provided with opposed humps 20 and 21, as shown in Fig. 5, in order to facilitate gripping of the iinger- @0 hold portions. I.

The lever effect for spreading the Abranches may be obtained by other methodsthan that described above. rlhus, as shown in Fig. 6 the sprin strip is bent to form a lurality of zloope portions 22 and 23 which' are joined togltherby another looped portion 24. The dgerhold portions 25 and 26 join together the branches 12 and 13 with the loops 22 and 23. Upon applying pressure to 100 the fingerhold portions it is obvious that the loop 23 will serve as a fulcrum upon which the branch 12', fingerhold 'portion 24, and loo 21 will move, thus causing the branches to e spread.

We claim: 1 n 1. A hairpin comprisin a single Hat strip of spring material dou led upon itself to fdrm a pair of parallel branches normally in contact their entire length and a looped i' end, said strip being alsoVs a ed to provide 3. A hair pin comprising a springstrip l doubled upon itself to fom a vpair of branches normally contacting throughout ranch" e branches normally contactin orm a pair of f Manne their entire length and ioined by a looped ortion, the junction point between the ooped portion and branches constituting a fulcrum, whereby pressure applied to the loop intermediate its ends serves to'separate sai branches apart.

4. A hair pin comprsin a spring strip doubled upon itself to orm a pair of throughout their entire len th and joinedv y an elongated looped portion, theopposite sides whereof are formed with humps to facilitate the gripping and compressing' thereof, and means incorporated with said looped portion whereby pressure applied to the lsides thereof operates to spread said branches.

In testimony whereof, We have hereunto set our hands.
