Application 'illed lay 7, 1825. Serial No. $38,707.

This invention relates to an improvement in hair pins especially adapted for use with bobbed hair, and has for its object the provision of an improved hair pin which is well adapted to engage with the hair in the ordinary manner to hold the same as fixed without danger of the pin slipping from its place, the pin being self-locking when cngaged with the hair.

'A further object is the provision of a hair pin having the advantages and capacities mentioned and which has all the advantages of theordinary hair self-locking, and w ich is of simple and durable construction, reliable and effective in operation and easy and comparatively inexpensive to manufacture.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be more fully described and particularly pointed out in the appended claim,

drawings forming a part of this specification, and in which:

Figure 1 is a view in elevation showing a hair pin constructed in accordance with the present invention, the arms of the hair pin being shown spread, and w v Figure 2 is a view similar to Fig. 1 but showing the arms-of the hair pin interlocked.

Referring to the drawings, the numeral 1 designates the head or body portion of the hair pin which takes the form of a bight or bend from which the arms or prongs 2 and 3 project. The general form of the hair pin is the same as that of the conventional pin, Midway between their ends the

arms

2 and 3 are formed with crimps 4 and 5 to better adapt the pin to engage and hold the hair. The arm 3 is longer than arm 2 and is substantially straight from the point at which it joins the body portion to its extreme in in addition to being- .outer ends. of the hair ewise substantially straight 6 designed to interlock with the outer end of the arm 3, asshown in Figure 2. The hook 6 opens outwardly with respect to the arm 2 and is gradually curved to render it easily engageable with and disengageablc from the arm 3.

With this arrangement the arms of the hair pin present continuous hair-engagim surfaces for practically their entire lengti so that all of the advantages of the ordinary hair pin is had. Along with these advantages is the additional advantage obtained by virtue of the interlocking of the extreme pin, whereby the hair pin is held in osition and the hair better confined on and between the hair-engaging surfaces presented by the arms of the pin for practically the entire length of the arms.

I claim:

A hair pin having a body portion and a pair of arms of uniform cross section throughout their extent, one of said arms being substantially straight from the body portion to its free end, the other arm being formed with a gradually curved outwardly opening hook at its outer extremity engageable and extendable around the outer end of the straight arm in substantially encircling engagement to interlock the arms, the arm' with the hook being substantially straight for practically its entire length, that is, from its head to itshook, whereby the arms of the hair pin present continuous hair-engaging surfaces for practically their entire length between which the hain is confined when the arms are interlocked, the terminal of said hook extending substantially longitudinally of the pin to facilitate its insertion in and removal from the hair without entanglement.
