GEORGE H. KNIGHT, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO WILLIAM R. LANE & (10., OF SAME PLACE.
ORNAMENTAL RING FOR JEWELRY.
SPECIFICATION forming part of Letters Patent No. 404,094, dated May 28, 1889.
Application filed October 27, 1888.
To all whom it may concern.-
Be it known that I, GEORGE H. KNIGHT, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Ornamental Rings for Jewelry, of which the followin g is a specification.
The nature of my invention consists in a ring formed from a seamless tube by turning the end portions of the tube backward, so that the ends thereof will abut against the surface of the tube and the sides will be in contact with each other, thus enabling me to produce from single-plated stock a jointless ring having a practically continuous plated surface.
Figure 1 represents an axial section of a single-plated seamless tube from which the ring is to be formed. Fig. 2 represents the same with the end portions of the tube turned over outwardly, so that the ends of said portions will abut against the surface of the tube and the sides will be in contact with each other. Fig. 3 represents the same with the ends turned inwardly and into contact with the inner surface of the tube and with each other. Fig. 4 represents the ring shown in Fig.2 when rolled down to form a band ring. Fig. 5 represents the ring shown in Fig. 3 when rolled down to form a ring of half-round crosssection.
In the accompanying drawings, A, Fig. 1, represents a seamless tube, which may be provided either with an interior gold-plated surface, a, or with a corresponding exterior goldplated surface, the said tube being readily formed from plated sheet-metal stock by means of suitable dies.
In forming my improved ring from a seamless tube, A, having an interior plated surface, a, I turn the ends I) b of the tube outwardly by means of the proper dies until the said ends are made to toucheach other at their plated sides and to abut against the former exterior base-metal surface, 0, of the tube. The jointless plated ring so formed Serial No. 289,332. (No model.)
will have a practically continuous plated surface, the ends I) b of the tube being firmly pressed together at the seam d with a plated surface contact.
Vhen making a plated band ring, I compress the ring shown in Fig. 2 between suitable rolls, so as to spread the same laterally and press the inner surfaces closely together, as shown in Fig. 4., thus forming a jointless plated band ring which will stand the test of dipping in acid and will have all the appearance of a solid-gold band ring.
The tube A can be plated upon its exterior surface and have its ends turned over interi- 6o orly, as shown in Fig. 3, the ends I) I) being pressed together with the plated surfaces be tween them at the seam d, the said ends abutting against the former interior base-metal surface, 0, of the tube; and the ring shown in Fig. 3 can be either rolled down to make a band-ring, as shown in Fig. 4, but in this case with the seam (1 upon the inside of the ring, or to make a ring having ahalf-round cross-section, as shown in Fig. 5.
I claim as my invention 1. An ornamental ring formed from a seamless plated tube and having the end portions of the tube turned backward, so that the ends thereof will abut against the surface of the tube and the exterior plated sides of the turned end portions will be in contact with each other, substantially as described.
2. An ornamental ring formed from a plated seamless tube and having the ends of the tube turned backward to meet at their plated side, substantially as described.
3. An ornamental ring formed from a plated seamless tube and having the ends of the tube turned to meet at their plated side and compressed to angular form, substantially as described.
GEORGE H. KNIGHT.
