Armstrong, Barrington, R. I., assignor, by mesne assignments, to Budlong, Docherty & Armstrong, Incorporated, Providence, R.

2 Claims.

This invention relates to an ear ornament and the method of making the same, or more particularly to the finding for an ear ornament.

In the making of ear ornaments it is usual to provide from tubular stock a short section which is internally threaded for the reception of the binding screw. This section is then soldered to a U-shaped portion of the ear wire as a separate'assembly operation. Soldering is an expensive operation and one which requires considerable skill.

One of the objects of this invention is to provide the U-shaped portion of the ear wire and the threaded portion which receives the bidding screw without the necessity of soldering.

Another object of this invention is to provide the U -sh.aped body portion and the portion which receives the binding screw piece so that soldering will be unnecessary and the parts will be strong and without joint.

Another object of this invention is to eliminate certain assembly operations.

Another object of this invention is to eliminate the necessity of cutting plated stock to provide the portion which receives the binding screw thus enabling the plating of the stock to cover all edges.

Another object of this invention is to provide an ear wire by such a method that no raw edges which come from cutting the stock will be provided, thus enabling the ear wire to be formed from plated stock with all parts or edges covered with the plate which goes to form the stock.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is an elevation illustrating the finished article which is made by the method of this invention;

Fig. 2 is a perspective view illustrating a U- shaped length of wire prior to any operations except that of bending being performed thereon;

Fig. 3 is a perspective view showing the end of the wire as flattened;

Fig. 4 is a perspective view showing the flattened end as partially bent into cylindrical shape;

Fig. 5 is a perspective view of the flattened portion bent into cylindrical shape;

Fig. 6 is a view similar to Fig. 5, illustrating a tapas being passed through the cylindrical portion;

Fig. 7 is a view similar to Fig. 5, illustrating the binding screw as placed in the cylindrical thread- 2 ed portion and as having one head assembled thereon;

Fig. 8 is a view similar to Fig. 7 but showing in section the other head of the binding screw as mounted thereon.

In proceeding with this invention I provide a length of wire and flatten and roll one end of it into cylindrical shape and then thread this portion for the reception of the binding screw. This eliminates the necessity of providing a separate part and soldering it onto the wire. The finding in this form may then be utilized as heretofore for the assembly of an ornament thereon, {and the mounting of the binding screw in posiion.

With reference to the drawings, in designates a length of cylindrical wire which has been bent into U-shape providing a short leg I l and a longer leg I2. The longer leg I2 is swedged as at l3 (see Fig. 3) so as to flatten the same and after this flattening the flattened portion i3 is annealed. A first rolling as at H (see Fig. 4) is provided so that this flattened portion I3 will extend partially about a cylindrical form. The next operation is swedging or rolling, which bends the flattened portion as at l5 (see Fig. 5) into cylindrical form, and thereafter the inner surface It of this cylindrical form is tapped as by a tap H, as shown in Fig. 6.

After the finding has been formed, such as on completion of tapping as shown in Fig. 6, a binding screw I8 as shown in Fig. 7 having one head i9 previously assembled thereon is threaded into the cylindrical tapped portion 15 as shown in Fig. 7 and thereafter a larger head 20 which serves as a handle is assembled on the other end of the screw l8 as shown in Fig. 8. Any ornament such as 2| (see Fig. 1) is assembled on the short arm I l of the ear wire so as to provide the same of an ornamental appearance. The ornament will have a jaw portion 22 which will be positioned axially opposite the head i9 and the lobe of the car may be positioned between the portions I9 and '22 and by turning the handle head 20 the screw l8 will be moved so as to engage the lobe of the ear and bind the ornament 2| thereon.

I claim:

1. The method of forming a finding for an ear wire comprising providing a length of plated wire cylindrical in cross section, flattening one end portion of said wire, rolling the flattened portion about an axis transverse to said wire and parallel to the flattened surface into cylindrical shape with the end at the juncture of the cylin- REFERENCES CITED The following references are of record in the file of this patent:
