HAIR-PIN.

Specification of Letters Patent.

Application filed November 23, 1915. Serial No. 63,122.

To all whom it may concern;

Be it known that I, MARTA KALINOWSKA,

a subject'of the Czar of Russia, residiiig at New York, in the countyand State of New York, have invented certain new and useful Improvements in Hair-Pins, of which the following is a full, clear, and exact specification.

This invention relates to hair pins, and has for its object to provide an improved hair pin of the type having pivoted prongs adapted to grip part of the hair placed between them for preventing the device from being jarred out, as is so apt to occur in dancing or active exercise. I

It is the aim of this invention to produce a'hair pin of this type which will effectively hold itself in the hair, but which has the appearance, when in place, of an ordinary hair pin having rigid prongs.

Another object is to so construct the hair pin that the handle or operating end of the movable prong will not be. apt to be accidentally displaced-and the device thus re- I leased from the hair.

Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views :Figure 1 is front elevation of a hair pin made substantially in accordance with this invention, a part of the fixed prong being broken away to disclose the rubber strip carried by the movable prong, and theopen position of the movable prong being indicated in dotted lines. Fig. 2 is a longitudinal section through the prongs of the hair pin, taken from side to side, the

head being broken away, and Fig. 3 is a" cross section throligh the closed prongs of the device. 1

The hair pin, as illustrated, comprises a fixed prong 1 and a movable prong 2 pivoted together at 3. The fixed prong is so called because it is permanently attached to the ornamental head 6 by the arm 4, whereas the movable prong has a diverging arm 5 which is movable with respect to the head 6, although said arm 5 is purposely made to closely resemble the arm 4 of the fixed prong and extends into uxtaposition to the head 6, as indicated at 7.

Both prongs are made in channel form,

the prong 2 being of less thickness so that it may 'fold into the channel of the fixed prong 1, as shown best in Fig. 3. The channel in the prong 2 is fitted with a filling strip 8, preferably of rubber, which provides an effective gripping surface within the channel of the fixed prong 1.

The'prongs are yieldingly held together 1n folded or gripping position, as shown in solid lines in Fig. 1, by a spring 9 housed in the channels in the arms 4 and 5. This the channel of the arm 5 and bears uponthe base of said channel for holding the prongs closed,.as will be readily understood. When it" is desired to open or spread the prongs apart, as when the hair pin is to be placed in the hair, it is only necessary to press upon the arm 5 of the movableprong and moveit toward the arm 4 of the fixed prong, whereupon the prong2 will be swung away from the prong 1, as indicated in dotted lines in Figs. 1 and 2. After the prongs have been inserted into the hair in open position, the pressure is removed from the arm 5 and the spring 9 immediately closes the prong 2 upon the prong 1, firmly gripping the hair between them. The channel form of the prongs makes them very strong and rigid, \while the rubber strip used in the channel of the movable prong provides a good and tenacious grip on the hair. The arrangement of the end 7 of the arm 5 of the movable prong in juxtaposition to the head, while the latter overhangs and is arranged in the same plane with said arm,

makes it almost impossible to accidentally Patented Aug-[15, 1916.

verging arms on the other side of the pivot,

and a head secured to the arm of one prong and extending across and into juxtaposition to the arm of the other prong and in the plane thereof, for the purpose specified 3. A hair pin comprising a pair of prongs pivotally connected together, both prongs having channels facing one another, one channel being narrower than the other and adapted to fold into the same and a strip of rubber secured in the narrower channel for the purpose specified. I

4. A hair pin comprising a pair of prongs pivotally connected together, one prong havside of the pivot, and a spring for yieldingly holding the prongs in closed position, said spring being entirely housed in the channels in said arms;

In testimony whereof I have signed my name to this specification.
