LOOKET.

To all whom it may concern: 7

Be it known that I, WARREN VILLIS, a citizen of theUnit'ed States, residing at North Attleboro, in the countyof Bristol and State of Massachusetts, have invented certain new and useful Improvements in Lockets, of which the following is a specification.

My invention has relation to lockets, in which may be safely enclosed and carried pictures, mementos and the like and consists in an improved method of constructing a locket and in the improved locket produced thereby.

My improved locket is made up of four parts, namely, a rim, back and front members, preferably of concavo-convex form, in order to form a shallow chamber between the two parts, when assembled, and a locklink member.

In the drawings:

Figure 1 is a front plan view of the locket;

Figure 2 is an edge view of Figure 1;

Figure 3 is a view of the rim;

Figure 4 is a View of the link member in perspective;

Figure 5 is a View of rim wire spirally wound upon a mandrel or former, with some of the studs aflixed;

Figure 6 is a cross-section of the locket on line 66 of Figure 1.

The object of my invention is to produce a locket, tight, cheaply made and assem bled, easily opened and closed, and of neat appearance.

To this end I form a rim of wire, drawn to a concavo-convex shape in crosssection, as shown in Figure 6, the hollow or concave face being the inner side of the rim,

, in use, and the convex face being the outer side of the rim in use. A suitable length of this wire is spirally wound, side by side, upon a mandrel or forming shaft, preferably of cylindrical shape, as shown in Figure 5, the inner hollow side, a, being next the mandrel M. A line, m parallel with the axis of the mandrel, is drawn across the coils of wire, and on each coil at an unequal distance from the line m, on either side of the line m. are aiiixed studs, S. Several of these pairs of studs are shown as affixed, in Figure 5, and such studs will be afiixed to every coil of the spiral and the Specification of Letters Patent. Patented Apr. llll, 1922.

1921; Serial No. 486,060.

spiral is then cut along the line m, the result being a multiplicity of split rings, 33, as shown in Figure 3, forming the rim, R. Or the spiral may be cut'be'for'e the attachment of the studs 8, and the studs S attached to the rings, separately.

The inner diameter of these rings, R, will be determined by the size of the mandrel, M, in accordance with the desired size of the finished locket, and it may be noted that the front and back conoavo-convex members, F, may be suitably formed, of crystals such as are used upon watches, and, as these are of various standard sizes, the rims B may be formed to receive any of the standard sizes desired, or sizes specially made, or the parts F may be one or both formed of other material than glass and of any desired size.

The lock-link L is formed of resilient material, preferably metal, curved, as shown in Figure 4:, and having apertures, 1, at each end, and carrying at its centre a spring loop which serves also as an attaching means for the chain in use. arms of the lock-link are formed depending flanges or skirts, 2. It will be noted that the studs S are set at unequal distances from the split in the ring, and that when the locket is assembled the split comes beneath the flange 2 and the ends are thus forced into and held in perfect alignment and the joint hidden. This function of the flanges is of importance, since the rings are originally formed as a spiral, are then cut into rings, but retain their spiral form until the ends are forced into alignment, and the ends have a tendency to return to the spiral if uncontrolled.

The locket is assembled by bringing the edges of a pair of frontand back members F together, the convex surface of the members being outwardly disposed, slipping the edges of the members F within the hollow, a, of rim R, pressing the ends of the rim into butted relationship, placing one aperture 1 of link L over one stud S and the other end of the link upon the other stud and pressing the link at the center to partially straighten and lengthen the link until the other aperture 1 slips over the other stud S. Upon releasing pressure on the link, the resiliency of the link will cause it to try to regain its original set or curve On the edges of the and will tend to draw the studs S toward one another, thus holding all the parts togetl'ier, until released by prying up one end of the link from one of the studs S, When the parts may be disassembled.

I claim:

1. The locket above described, made up of a front and a back member; a rim, formed as a split ring, surrounding and engaging the edges of the front and back members; a pair of studs, spaced apart and each fast on the split ring on opposite sides of the split; a spring link engaging both studs and drawing the rim and holding the rim and front and back members in fixed relationship.

2. The locket above described, made up of a front and a back member; a rim, formed as a split ring, surrounding and engaging the edges of the front and back members and carrying on opposite sides of the split and at unequal distances therefrom, a pair of studs; a link formed with a spring loop midway of its length and having depending flanges on both sides of each arm of the link, the link engaging both studs and the flanges holding the ends of the split ring in perfect alignment.

Signedat North Attleboro, Massachusetts, this 18th day of July, 1921.

WARREN E. WILLIS.
