Abstract:
1. An apparatus for distributing gobs of molten glass from a gob feeder in a predetermined sequence through stationary channels onto molds of a plurality of sections of a glass forming machine, said apparatus comprising: at least one scoop channel having a first end adapted to receive said gobs from said feeder and a second end alignable with one of said stationary channels, said scoop channel being rotatable about an axis for aligning said second end of said scoop channel with said stationary channels; a pinion attached to said scoop channel proximate to said first end thereof, said pinion being fixed to and rotatable with said scoop channel about said axis; an electrical motor for rotating said pinion and thereby rotating said scoop channel about said axis; a gear train transmitting torque from said motor to said pinion, said gear train including a screw engaged with said motor, said motor being adapted to rotate said screw in a reciprocating manner, a worm wheel engaged with said screw and rotatable in response to rotation of said screw, a toothed wheel mounted coaxially with said worm wheel and fixed thereto so as to rotate with said worm wheel, said toothed wheel driving said pinion for effecting rotation of said scoop channel upon rotation of said screw by said motor; an intermediate toothed wheel engaging both said pinion and said toothed wheel, said intermediate toothed wheel transmitting torque from said toothed wheel to said pinion for effecting rotation of said scoop channel upon rotation of said screw by said motor; and said intermediate toothed wheel comprising first and second partial toothed wheels positioned in overlying relation coaxially aligned with one another, said first and second partial toothed wheels being rotationally adjustable with respect to each other about an axis of rotation in order to minimize clearance between themselves and the pinion and the toothed wheel at the periphery thereof, means being provided for fixing a relative rotational position of said first partial toothed wheel to said second partial toothed wheel.
