ABSTRACT:
This relates to a blow mold of a large capacity which is particularly configurated to replace two adjacent blow molds in a blow molding machine of the Ferris wheel type. The blow mold includes an inner mold half which will bridge the supports for two existing smaller molds and an outer mold half which is formed in two segments with each of the segments being independently mounted on the supports for two separate prior radially outer blow mold halves. Thus, an existing machine may be readily converted to make much larger blow molded articles then those for which it was originally intended. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of this application.
