Latest Patents

Franklin W Held holds a patent for an "Apparatus and method of making hollow articles." This invention is specifically designed for creating hollow racquetball balls. The process involves molding a mass of vulcanizable elastic material into a hollow semi-spherical form. The bulk of the material is heated to fully vulcanize it, while a portion around the edge is cooled to remain only partially vulcanized. Two semi-spherical forms are then abutted under pressure, and heat is applied to the uncured edges to fully vulcanize and bind them together, resulting in a seamless ball. The apparatus includes mold means that define a hollow semi-spherical cavity, with a cooling chamber at the open edge to prevent vulcanization at the edges during the heating process.
