Abstract
Abstract A glassware forming machine including means for distributing gobs of molten glass to individual sections of the machine at a predetermined rate, drive means responsive to electrical power of a selected frequency generated by a power source for driving the gob distributing means at the predetermined rate and an automatic control means responsive to timing signals for controlling each of the individual sections in a predetermined timed sequence of steps for forming the glassware wherein the power source generates the timing signals at a frequency proportional to the selected frequency of the power source. Each piece of glassware is formed during a machine cycle which is related in duration of the gob distribution rate and typically is defined in terms of 360°. The power source includes means for generating a reference signal at a frequency which determines the selected frequency of the electric power and means responsive to the reference signal for generating the timing signals at the frequency required for defining 360° per machine cycle.
