PIN TONGUE.

Application filed October 2, 1922.

1 all whom it may concern:

Be it known that I, LOUIS E. SAnLnn, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Pin Tongues, of which the following is a specification.

This invention relates to certain new and useful improvements in pin tongues of the type used in connection with brooches and other articles of jewelry, and the primary object thereof is to provide a pin tongue construction and method of making wherein involves a piece of wire having its head or pivotal eye formed of a separate piece of material which is rigidly secured to the body of the pin by swaging and without the use of extraneous fastening means to thereby provide a strong and reinforced head for the tongue.

A further object of the invention is to provide a pin tongue construction which permits of easy and expeditious assemblage and subsequent swaging of the parts.

The invention still further aims to provide a pin tongue construction which in- TOlVGS a minimum of material and labor.

The invention has still further and other objects which will be later set forth and no manifested in the course of the following description.

In the drawings Figure 1, is a plan view of the blank from which the body of the tongue is made;

Figure 2, is a view of the blank arranged within the cup preparatory to swaging;

Figure 3 is a section on line 3-3 of Figure 2;

Figure l. is a detail perspective view of the cup and Figure 5, is plan of the completed pin.

In proceeding in accordance with the present invention, a preferably wire blank 1 is employed which has a tapering or is pointed formation, as depicted in Figure 1,

of the drawings.

The first step resides in bending of the wide or thick end of the tapered or pointed blank into the form of an eye or circle havso ing an open center as indicated at 2. A metal cup 3 is provided having a slot 4 eX- Serial No. 591,840.

tending transversely of its rim, the diame ter of the cup being such so as to receive the circular end 2 of the pintherein, with the adjacent part of the blank extending through the slot 4 of the cup as illustrated in Figure 2, the end 2 resting or seating upon the bottom of the cup as shown in Figure 3.

With the two parts in this assembled relation, the same are subjected to a swaging operation so as to produce the finished structure of Figure 5, wherein it will be noted that the part of the rim of the cup which projects above the eye 2 lies superimposed upon the latter, aflording a rigid and strong connection between the cup and tongue and providing a reinforced head for the tongue.

At the same time, the bottom of the cup has a hole punched therein in register with the open center of the eye 2, in order to receive the usual pivotal pin or pintle for the pin tongue. I

The eye of the tongue is thus not only peripherally surrounded by the cup, but the opposed faces of the same are also engaged by the cup bottom and the projecting or top part of the cup which is swaged over the adjacent face of the eye, while the slot which receives the tongue forms an interlocking connection therewith.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is r In a pin tongue, a body having an eye at one end, and a cup having a bottom and a rim, the rim having a slot extending transversely thereof, the eye being received in the cup and extending through the slot and having one side face thereof seated on the cup bottom, the free edge of the rim being extended inwardly and impinged against the opposite side face of the eye, the bottom of the cup having an aperture in register with the in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. v

LOUIS E. SADLER.
