Assembly for casting individual jewelry rings of precious metals has a base carrier to take larger and smaller cylinder bodies with a ring width gauge and a sleeve to define the hollow zone of required dimensions

摘要

The system for individually casting jewelry rings of precious metals has a base carrier (1,4) to take a cylindrical body (5) of a larger dia. A cylindrical body (6) of a smaller dia. is placed over the larger body (5). A sleeve (7) is pushed over the larger body (5), with an inner dia. matching the outer dia. of the body. A ring width gauge (8) is fitted to the base plate (1), at the sleeve (7), so that the sleeve (7) slides against the bodies (5,6) to define a hollow zone (9) of the dimensions of the ring to be cast.
