Mechanical Mold Manipulating Systems
a. Early bottom hinged molds were opened and closed around the parison
formed bottle by a mold boy and a levering rod on the back of the front
dropping mold half.
b. 3-part molded shoulders and necks. These shoulder molds were hinged
to the backside of each mold half and had to be closed over the parison
formed bottle, for the final blow of the bottle maker.
c. H. Ricketts’ Patents – were involved with foot and hand, mold
segments levered in mechanical manipulation. His first patent was made
in 1821. Quite often these early bottles were embossed on the shoulder
with “/ PATENT \”. Many of them were embossed on the bottom in an
outside periphery ring, with “/ H. RICKETTS & Co. – GLASSWORKS – BRISTOL
\”. Some were later embossed with “/ H. R. & Co.\” in that same ring form.
