Patent ID: 7543461

Claim:
A gob deflector having an entry end for receiving molten glass gobs and exit end for directing the glass gobs into a blank mold of a glassware forming machine, said deflector having a continuous curved portion between said entry and exit ends, said curved portion having continuously concave arc defined by an upper curve contiguous with said entry end, and a lower curve different from said upper curve and contiguous with said exit end, said lower curve being defined by the equation r 1 =C 1 /θ 1 P1 , where r 1 is radius at angle θ 1 , and C 1 and P 1 are constants, said upper curve being defined by the equation r 2 =C 2 /θ 2 P2 , where r 2 is radius at angle θ 2 , and C 2 and P 2 are constants, said curves having minimum radii r 1 min =r 2 min where said curves meet at a central portion of said curved portion, said constant P 1 being non-zero and in the range of 0.4 to 0.7.
