SAFETY HAIR-PIN.

To all whom it may concern:

Be it known that I, JULIUS KOTNER, a subject of the Kingdom of Hungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Safety Hair-Pins; 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 comprehends improve ments in hair pins and relates more particularly to those which are so constructed as to clamp against the hair and thus prevent loss.

The primary object of the invention resides in the provision of a safety hair pin which is of extremely simple construction, cheap to manufacture, and which may be easily inserted into and withdrawn from the hair without mussing it.

A more specific object of the invention resides in the provision of a hair pin having a pair of spring pressed prongs which are adapted to be moved toward or a 'ay from the main prongs, said spring pressed prongs serving to clamp the entire pin firmly in position.

The invention also aims to generally improve hair pins of this nature to render them more useful, practical, and commercially desirable.

lVith these and other objects in view, as will become more apparent as the description proceeds, the invention consists in cer tain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a side elevation of my improved safety hair pin, the face plate being partly broken away and the movable prongs shown in engagement with the stationary prongs, Fig. 2 is a fragmentary view similar to Fig. 1, showing the movable prongs away from engagement with the stationary prongs, Fig. 3 is an edge elevation, and, Fig. l is a transverse section taken on the plane of line 41 of Fig. 3.

In the preferred embodiment of my invention, I provide a somewhat U-shaped hair pin having a head 5 and the prongs or legs 6, which may be of wavy formation, as

Specification of Letters Patent.

shown in the drawings. A recess 7 is formed in the head and opens upon one face thereof. The main portion of the recess forms an elongated channel which opens upon the side edges and inner edge of the head. The remaining portion of the recess is V-shaped, as indicated at 8, and opens upon the main portion centrally of its ends.

A pair of locking prongs 9 and 10 of a somewhat shorter length than the prongs 6 and shaped to conform to the inner edges thereof, are provided for the purpose of clamping engagement with the hair. Rectangular blocks 11 and 12 are formed upon the upper ends of the prongs 9 and 10, respectively, and project entirely to one side thereof. These blocks are received within the body portion of the recess 7 and are held normally in their extended positions by means of the Hat metal V-shaped spring 13. This spring seats within the V-shaped portion 8 of the recess 7 and its extremities are fitted within notches 14 formed in the opposed ends of the sliding blocks. It will be noted upon reference to Fig. 1 that the notches 14: are shaped so as to allow the sliding blocks to be forced together without binding upon the spring.

A face plate 15 having the extensions 16 formed upon its inner edge is secured to the recessed face of the head 5 and to the prongs G by means of suitable fasteners 17 and retains the slidingblocks and spring in their proper positions.

lVhen the pin is inserted into the hair the sliding blocks 11 and 19. are forced toward each other which brings the prongs 6 and 9 and 10 into the relative position shown in Fig. 2. \Vhen the pin is in proper place the pressure is released from the sliding blocks and the spring 13 forces the locking prongs 9 and 10 toward the prongs G,without clamping against the hair.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that I have provided a very simply constructed safety hair pin, the parts of which may be easily assembled, and which may be easily inserted into and removed from the hair without mussing the same.

It is to be understood that while I have shown and described the preferred embodiment of my invention, I do not wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will fall within the spirit and scope of the invention.

Having thus described my invention, what I claim is 1. A safety hair pin comprising a U- shaped pin having a head and a pair of prongs, blocks slidable within recesses formed in the head, looking prongs formed upon said blocks for engagement with the inner edges of the first mentioned prongs, and spring means for forcing the blocks away from each other, whereby the locking prongs are moved toward the prongs of the U-shaped pin.

2. The combination with a hair pin including a recessed head and a pair of prongs, of a pair of sliding blocks movable longitudinally within said recess, a locking prong formed upon the inner end of each of said sliding blocks for engagement with the inner edge of one of the firstmentioned prongs, and a V-shaped spring also positioned within the recess formed in the head and having its extremities inserted within notches formed in the opposed ends of the sliding blocks, said spring tending to force said blocks normally away from each other.

In testimony whereof I afiiX my signature in presence of two witnesses.

JULIUS KOTNER.
