FRANCIS J. WAKEFIELD, OF AT'ILEBORO, MASSACHUSETTS, ASSIGNOR TO ARTHUR A. IVJIGRiAE AND CHARLES P. KEELER, BOTH OF ATTLEBORO, MASSACHUSETTS.

LOCKET.

To all wit-omit may concern:

Be it known that I, F RANOIS J. ann- FIELD, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements 111 Lockets, of which the following is a specification.

My invention relates to lockets, and has for its objects the ends commonly sought in such structures, and particularly to pro vide a structure capable of being stamped out of thin metal at a minimum of expense, and wherein the parts may be assembled and engaged without the employment of solder; to avoid the use of the usual hinge construction, and insure a closure of the parts without the use of any independent fastening means.

To the above ends essentially my inven tion consists in such parts and combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification, Figure 1 is a rear elevation of my locket, Fig. 2, a side elevation of the same, Fig. 3, a section on line mm of Fig. 1, Fig. 4, a top plan View of the body of the locket with the cover removed, Fig. 5, a front elevation of the locket cover, Figs. 6 and 7 are partial enlarged sections on line a: a: of 'Fig. 1, showing the parts in open and closed positions, respectively, Fig. 8 is an enlarged section on lineyg of Fig. 1,Fig 9,alike section on line y of Fig. 1 with the cover removed, and Fig. 10, an enlarged front view of a portion of the locket including and adjacent the pivotal joint, showing a portion of the rolled over flange broken away.

Like reference characters indicate like parts throughout the views.

My locket comprises a body portion A and a cover B, each of concavoconvex outline, adapted when brought into engagement with each other to form a thin structure. The body A is provided with an outwardly and inwardly rolled over flange a, having its inner edge resting against the upper face of a flatannular disk or field piece C, and holding the latter with its peripheral edge in tight frictional contact with the inclined inner face of the body portion A. The flange a has a small portion thereof cut away to form a recess (Z extending to the Specification of Letters Patent.

horizontal plane of the field piece C. At a point diametrically opposite the recess (Z the flange a has a rectangular recess 6 cut out of a portion of the flange extending downwardly into contact with the field piece, whereby the remainder of the flange 6 forms a shoulder 6 outside the plane of the field piece for a purpose to be later set forth. The cover B has integral with its periphery a perforated lug f, and upon its edge, diametrically opposite the lug f, a curved lug G, and provided with lateral projections g upon its ends forming a reduced intermediate portion 9 between the outer portion of the lug G and the body B of the cover. The cover is engaged with the body through the projections g which loosely enter the rolled over flange A at each side of the slot 6, so that the lug G, as shown in Fig. 7, has a bearing on its outer edge against the field piece C when the cover B is open. Vhen in open position the portion of the lug G nearest the cover contacts with the shoulder e which forms a stop for the downward movement of the cover. lVhen the cover is closed, the lug f is seated in a cavity (Z, and the cover is held in closed position by virtue of the resiliency of the rolled over flange a, whose edge yields inwardly when the edge of the cover B is pressed into frictional engagement therewith in its course to the upper face of the field piece C, against which the cover rests in its closed position.

It will be observed that this structure lends itself to ready assemblage in that the blank comprising a body portion A before having its flange a rolled over is laid upon the lower die of the press, and then the field piece C is placed upon the concave surface of the body A and concentric therewith, and finally the cover B is placed upon the prior two parts with the lug G located in such a position that the flange a when ultimately formed will close upon the projections 9. Then the plunger or upper die will descend and roll over the flange (5, thus by a single stroke of the tools engaging all the three parts of the locket in their final form.

lVhat I claim is,

1. In a locket, the combination of a body, a field piece seated against the body, a rolled over flange extending above the plane of the field piece in engagement with the field piece and provided with a cut away portion forming a stop above the plane of the field piece, a cover, a lug upon the cover extending. into the cut away portion of the flange, and lateral projections upon the lug extending loosely into the flange at each side of the cut away portion.

2. In a locket, the combination of a concavo-convex body, a field piece seated upon the body, a rolled over flange integral with the body in contact with the field piece and adapted to hold the field piece in contact with the body, said flange being provided with a cut away portion above the plane of the field piece, a cover, a lug upon the cover extending into the cut away portion adjacent the field piece and adapted to engage the field piece when the cover is open, and lateral integral projections upon the lug extending loosely into the rolled over flange above the face of the field piece.

In a locket, the combination of a body, a field piece resting against the body, a resili ent flange upon the periphery of the body and integral therewith extending above the plane of the field piece and in engagement with the field piece, said flange being pro vided with a recess ex ending to-the plane of the field piece, said flange being also pro vided with a cut away portion at a point diametrically opposite the recess, a cover, a lug upon the cover registering in the recess, a second lug upon the cover at a point diametrically opposite the first mentioned lug and extending into the cut away portion, and ears integral with the second lug extending loosely into the flange.

4. In a locket, the combination of a body, a field piece in the body, a resilient rolled over flange integral with the body above the surface of the field piece resting against the field piece, said flange being provided with a recess extending to the plane of the field piece, the flange being also provided with a cut away portion, a cover, a lug upon the cover registering in the recess, a second lug upon the cover extending into the cut away portion, and projections integral with the second lug loosely extending into the portions of the flange adjacent the cut away portion and exterior of the field piece.

In a locket, the combination of a body, a hollow resilient flange upon the periphery of the body provided with a cut away portion, a cover, a lug upon the c ver extending into the cut away portion, and lateral projections upon the lug extending loosely into the portions of the flange adjacent the cut away portion.

6. In a locket, the combination of a body, a resilient flange integral with the body and substantially circular in cross section, said flange being provided with a recess, and provided at diametrically opposite point with a cut away portion, a cover, a lug upon. the cover adapted to extend into the cut a "ay portion, a second lug integral with the cover adapted to register in the recess, and lateral projections upon the first lug loosely cnering the pcztions of the flange adjacent the cut away portion.

in testimony whereof I have affixed my signature in presence of two witnesses.
