STUD AND CLASP.

SPECIFICATION forming part of Letters Patent No. 234,337, dated November 9, 1880. Application tiled Septcmber24,1880. (Nomodel.)

To all whom tt may concern Be it known that l, MERRITT B. SCOTT, of Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Studs and Clasps; and I do hereby declare that the following is a full and complete description of the same.

This invention relates to that class of clasps for which Letters Patent were granted to me October 2S, 1879, No. 220,992, and is an improvement on the clasp so patented to me.

It consists merely in the improved mode of construction ofthe same, with a view to econonly, strength, and efficiency.

That others may more fully understand my invention, I will particularly describe the same, having reference to the accompanying` drawings, wherein- Figure l is a perspective view of my clasp complete. Fig. 2 is a diagram of the blank in its first form. Fig. 3 represents the blank in its second form. Fig. 4 is a longitudinal section. Fig. 5 is an end elevation, showing the bent form of the parts bl) and d d, forming the post and shoe.

The frame is composed ot' a single piece of sheet metal shaped as shown in Fig. This blank comprises the central part, a, with the lateral arms b extending from opposite edges, near one end, and the semicircular plates d at the ends of' said arms. At the opposite end of said central part, a, the lateral ears c care formed.

Forsmall clasps it is more convenient to cut the notch g after the blank has been punched, as in Fig. 2; but forlarger clasps it may be formed complete at the first punching.

The arms l) l) being bent backward and the ends brought together constitute the post of the stud, and the semicircular plates d d being similarly bent outward and adjusted in the same plane, with their straight edges contiguous, constitute the shoe, and the plate a then constitutes the face, to which any ornament may be attached. If it is desired to use the article only for the purpose of a stud, a platecover, h, may be laid over the shoe d, and its edges turned over the same for the purpose of finish and strength. For the purpose of a clasp, however, the arm Cr is pivoted to the ears e c, and the sharp-pointed spur t' at the end thereof is adjusted to pass into a hole in the plate c opposite the arms b b, and is held firmly in that posit-ion by the spring J, one end of which is riveted to the plate a between the arms l) b. The free en d ofthe spring .I rests upon the square k on the arm G, and thereby holds the same either closed or open, as the case may be.

Having described my invention, what I claim as new is- 1. A stud or clasp with the face, post, and shoe all constructed of a single plate or blank shaped as shown, combined with a spring, J, riveted to said plate a, and the arm G, provided with the spur t' and square 7s, substantially as set forth.

2. A stud or clasp frame constructed of a single piece or blank, as shown-that is to say, a plate, a, arms b b, and semicircular plates d d, bent together as described, so that said plate a forms the face, the arms b b constitute the post, and the semicircnlar plates constitute the shoe7 as set forth.

3. In a stud or clasp, a blank or piece, a, cut with projectingarms b b, said arms adapted to be bent so that the part a, will form the face, and the arms b b Will form the post to support the shoe d.
