IMPROVEMENT IN THE MANUFACTURE OF JEWELRY-BASES.
Specification forming part of Letters Patent N0. 135,087, dated January 21, 1873.
CASE 0.
- lowing is a specification:
The invention consists in a new mode of forming an inner barrel on a jewelry-blank, as hereinafter fully described and subsequentl y claimed.
Figure 1 represents, in plan and section, the first blank employed Fig. 2, the second blank; Fig. 3, the completed article; Fig. 4,
' the mandrel and ring; Fig. 5, a detail plan and sectional view of ring; Fig. 6, a view of bnrnisher Fig. 7, the mandrel with article finished thereon.
A represents a blank, having bottom a and barrel a at a sharp angle, a to each other. B is a second blank, formed from the first and differing from it only in having the hole b cut out of it so as to leave the edge B. (l is the article or product ready to receive the studs, buttons, or settings, having the internal barrel c concentric with the one 00, and an intermediate groove or channel, 0. D is a mandrel having the cavity 01 corresponding in form to hole b and the mandrel edge d of a thickness corresponding to the width of blank groove 0.
The blank B is turned bottom upward over the edge d of mandrel, and ring F placed over blank B, and the blank edge B turned over inwardly with a burnisher, E, until at right angles to bottom. This produces the base'U, which is now ready for receiving the stud or setting.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The mandrel D, having edge d and cavity d, constructed as described, and combined with a burnisher and ring, as and for the purpose set-forth.
'2. The method of forming on the blank A an inner barrel, 0, concentric with outer barrel, substantially as described.
SHUBAEL OOTTLE.
