lMPP OVEMENT IN HAIR-PINS.

Specification forming part of Letters Patent No. 43,439, dated July 5, was.

To all whom it may concern.-

Be it known that I, ANDREW T. THAYER, of the city, county, and State of New York, have invented a new and useful Improvement in Ladies Hair-Pins; and I do hereby declare that the following is a full, clear, and exact description ther eot, which will enable any person skilled in the art to make and use the same, referencebeing had to the accompanyin g drawings, making a part of this specification, in which- Figure 1 is a view of my invention in use or appli ad to the hair; Fig. 2, a detached and enlarged side view of the same; Fig.3, an edge view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to .obtain a hairpin which will not slip out of the hair or become casually loosened and detached; and to this end the invention consists in construct ing the pin with a circular spring at the bend orjunction of the two prongs of the pin, as hereinafter set forth, whereby acertain de gree of elasticity is obtained sut'ticient to cause the two prongs, when pressed in contact and inserted into the hair, to press or bear against the same and bethereby firmly held in position.

'lhe hairpin I construct, as usual, out of a single piece of wire bent or doubled so as to form two prongs, a, a, of equal length, and at the bend I flatten or compress the wire and give at a circular form, so as to constitute a spring, I), as shown clearly in Figs. 1 and 2. The compressing or flattening of the Wire at the bend orjunct-ion of the prongs a (a increast s the elasticity of the spring I) and renders the same more durable than it otherwise would bG-lll fact, a perfect spring is obtained, and the prongs a a are bent obliquely outward from the ends thereof, as shown more particularly in Fig. 2, the spring I) having a tendency to keep the pron gs a a in that position.

In applying the pin to the hair the prongs a a are pressed together in contact, as'shown in red, Fig. 2, and the spring I), in consequence of having a tendency to force the prongs a m apart, cause the pin to be bound in the hair, so that it cannot become casually loosened or detached.

Having thus described my invention, I claim as new and desire to secure by Letters Patent, as an improved article of manufacture A hair-pin constructed or formed with a circular spring, b, at the junction of its prongs a a, substantially as herein set forth.

ANDREW T. THAYER.
