Application filed October 29, 1917. SeriaI No. 199,026.

To all whom am}; concern:

Be it known that we, JOHN W. SoHoELL- NER and J OSEPH P. ROWLEY, both citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Methods of Manufacturing Connecting Members or Links for Cuff- Buttons, of which the following is a specification.

This invention relates to an improved method of manufacturing connecting members or links for cuff buttons. The sort of connecting members which we have in mind are those, in the form of a loop, or preferably a figure 8 to each end of which a cuff button is to be joined by means of another link or loop or ring. Such connecting members haveheretofore been made of wire stock bent to shape and with the ends soldered to gether. We propose by our invention to use flat material, and because of the distinctive method employed in manufacturing we are enabled to use flat material of base metal plated on but one side with precious metal and obtain as the result ofthe process a link or connecting member of which all visible surfaces are plated.

Inthe accompanying drawings we have.

illustrated, from figure to figurethe steps of the process, and the last two figures show the finished article.

Figure 1 illustrates in plan and edge view the flat blank with which manufacture begins; Figs. 2,3, 45, 5 and 6 illustrate in plan and section respectively further steps in the at 19 and the sides at 11, the precious metal surface 9 being on the outside.

The next operation is to bend in the upper edge portions of the flange 11 tothe position shown in Fig. 8 so that the cup is partially closed with the sides of the cup rounded. As the next step the upper edge portlons of the flange are bent in toward the bottom of the cup, as indicated in Fig. 4. Next, the bottom of the cup is punched out as indicated of the bottom surrounding the cut-out portion 12 are bent up to make or assume an overlapping relation with the downwardly bent flange 11, as indicated in Fig. 6. The result is'to produce a continuous ring which is split circumferentially on its inner surface where the split is substantially invisible, and it will be noted that all of the visible surfaceof this ring is plated. Moreat 12 in Fig. 5 and thenthe'edge portions,

over, we. prefer to conduct the manipulation so that the cross section of the complete ring I shall be rounded as indicatedin the'sectional view of Fig. 6. Finally, the ring of Fig. 6 7 is squeezed diametrically so that it assumes the shape of Fig. 7, providing two end loops or openings by which connection may be made with the cuff buttons.

It will be evident that the various changes of shape of the material may be made by different well known operations and we do not wish to be limited to the use of any particular method of performing any single step of the method, the invention so far as the method is concerned consisting in the sequence of manipulations whereby we are enabled to proceed from the flat blank to the finished article.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of our invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense, except as required by the scope of the claims.

2. The method which consists in providing a flat blank manipulating the same to give it a cup shape, turning in the edge of the cup, removingthe bottom of the cup and turning up the edge of the blank surrounding the cut-out portion and lapping the same over the inturned edge first mentioned.

3. The method which consists in providing a flat circular blank of base metal plated on one side With precious metal, drawing the blank to form a cup, With the precious metal surface outside, turning the edges of the cup inwardly and downwardly toward the bottom of the cup, punching out the bottom from the cup and turning the edges of 'the blank surrounding the cutout portion upwardly to meet the downwardly and inwardly turned edges ofthe flange, and then squeezing the resultingring along a diametrical line, substantially as described.

In testimony whereof We affix our signatures.

JOHN W. SGHOELLNER. JOSEPH PJROWLEY.
