ISAAC M. POTTER, OE PROVIDENCE, RHODE ISLAND.
MANUFACTURE OF SHEET-METAL FINGER-RINGS, 85C.
Specification of Letters Patent No. 30,246, dated October 2, 1860.
To all whom it may concern.'
Be it known that I, ISAAC M. POTTER, of the city and county of Providence, in the State of Rhode Island7 have invented a new and useful Improvement in the Method of Making Finger-Rings; and I do hereby declare that the following specitication.y taken in connection with the drawings making a part of the saine, is a full, clear, and exact description thereof.
Figure l, is a view of the sheet metal as it comes from the die represented in Fig. 3. Fig. el shows a side view of the finished ring and Figs. 5 and 6 views of the former by which the result to be described is effected.
Hitherto finger rings which belong'to that class of work which is known to the trade as soft solder jewelry have been made by the following process: The sheet metal of which the ring is to be made having been struck up in a die the interior is filled with pewter solder 'and then the ring is formed about a mandrel. The only object of the solder is to enable the workman to fashion the ring about the mandrel as otherwise the metal would be crimped as it is termed. It is obvious that in making cheap rings of this class the cost of filling the sheet metal blank must constitute a large item in the expense of manufacture.
My improvement consists in bending the blank after it has been struck up in a die without first filling it with solder. For this purpose I use a metallic former (Fig. 5), the dia-meter of which is smaller than that of the ring to be made. The former has upon its surface the same figure or device that is upon the blank after it comes from the die', so that the elevations and depressions in the under surface of the blank will fit the corresponding elevations and depressions on the former. The blank having been struck up by the die as shown in Fig. l, the former (Fig. is placed on a mandrel and the blank being adjusted tothe former so that the ligure on the two shall correspond it can be as perfectly bent into the form of a ring as if the interior had been first filled with soft metal.
IVhat I claim as my invention and desire to secure byrLetters Patent is- The use of a former (Fig. 5) when used in the manner described for the purposes specified.
