Mold apparatus for forming rings

A mold apparatus for forming various sized wax castings for finger-rings, comprising:

• a drum-housing, slightly larger than a finger ring;
• having a casting-bore disposed therein;
• a lower end-plate arranged to be removably received over the lower end of said drum-housing;
• an upper end-plate arranged to be similarly removably received over the upper end of said drumhousing;
• said drum-housing and said upper and lower end-plates thereby defining a casting chamber therein;
• means, comprising a single supportpost, for removably securing said endplates to said drum-housing;
• said support-post being positioned in the finger-opening of the wax-casting of a finger-ring;
• said support-post coacting with said drum-housing to define a casting cavity corresponding to the wax-casting of a fingerring;
• means positioned within said mold apparatus for allowing the wax casting material to be injected therein;
• finger sizing means, comprising one of a variety of predeterminedsized finger-ring bands adapted to be removably positioned within said casting bore, to encircle the outer surface of said support-post, for establishing the size of the finger-opening of the wax casting of a finger ring;
• ring sizing means, comprising one of a variety of predetermined-sized ring bands adapted to be removably positioned within and adjacent the inner surface of drum-housing, for establishing the overall size of the wax-casting of a fingerring.
