CLIFFORD e. KING, or PROVIDENCE, RHODE ISLAND.

v METHOD OF FORMING `THE ORNAMENTAL BODY OF AN EAR-RING.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application led July 17, 1919. Serial No. 311,545.

To all whom t may concern:

Be it known that I, CLIFFORD G. KING, a citizen of the United States, .residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in' Methods of Forming the Ornamental Body of an Ear-Ring, of which the following is a specification.

My invention relates to earring bodies of crescent form.

These bodies are usuallymade from iiat precious metal plated material, in which case it is obviously essential that the base metal overlaid by the precious metal be not exposed. It is also imperative that the internal chamber formed by the central enlargement of the body be everywherel sealed against any access of finishing liquids. It has heretofore been customary in forming such bodies to solder together two crescent shaped shells which produced objectionable seams and openings.

The essential objects of my invention are to attain the advantages and avoid the disadvantages above enumerated; to cheapen the process construction; to reduce the weight of the body to a minimum; and insure a construction adaptable for bodies of small size.

The invention consists in such steps and combinations of steps, and in such parts and combinations of parts as are included within the scope of the appended claims.

In the accompanying drawings which -form a part of this specication.

Figure l is a longitudinal section of the original tube from which the Vbody is ultimately formed,

Figs. 2 and 3, a central longitudinal section and front view respectively of the same after the compression and .elongation step,

Figs. 1 and 5, aside elevation and front view respectively of the same after the bending step,

Fig. (i, a section on line 6 6 of Fig. 4,

Fig. 7 a front view of a completed earring, and

Fig. S, a longitudinal central section of the end portion of a pair of dies. n

Like reference characters indicate like parts throughout the views,

In carrying out my invention a cylindrical tube 9 of metal, preferably provided with a precious metal skin or plated exterior surface 10, is, by the tapering dies of a reducing machine or otherwise, compressed or reduced toward its ends into conical portions 11. The reduction also elongates the member and forms solid extremities 12 due to the maximum accumulation of metal atl the points of greatestcompression. By the described action of the dies also the plating material at the extremities is closed over completely covering1 the base metal, as at 13.

Upon an arbor or otherwise the member 9 is next bent up into crescent shape, as shown in Fig. 5.

The member is in this instance adapted for the reception of an ear wire 14C by cutting a central longitudinal slot 15 in one of the solid ends l2, to form bifurcated portions or ears 16, which are drilled to form perforations l? to receive the pintle 18 of the ear wire. The opposite solid extremity of the member 9 is nicled by any suitable tool to form a cavity 19 for the reception ofthe i free end of the ear wire.

The reducing dies herein shown in part comprise similar upperand lower members, 2l, provided with longitudinally disposed tapering cavities terminating in rounded end portions 23.

I claim,-

l. The method of forming the ornamental body of an earring consisting in compressing and elongating an empty tube into the form of a double cone comprising solid ends, and then bending the tube into the form of an incomplete ring. y

Q. The method of forming the ornamental body of an earring consisting in elongating and tapering by compression an empty tube to forni a solid metal mass at each end of the tube, next bifurcating the mass at one end, perforating the bifurcated portion, and

finally forming va cavity in the mass at the signature.
