Abstract
Abstract For glassware forming apparatus, a gear drive is provided for connecting the main horizontal drive shaft, which rotates continuously in one direction, to a vertical output shaft to oscillate the output shaft, on which the fluid motor for the 90* pushout is mounted, through an angle of approximately 90* for oscillating the 90* pushout fluid motor assembly through a corresponding 90* arc to sweep glassware articles from a dead plate through an arcuate path on to a continuously moving conveyor. The gear drive for oscillating the vertical shaft through 90*, also controls the delivery of air pressure to the fluid motor, through one air line or the other, in timed relation with the oscillating movement of the vertical shaft. Adjustment means are provided which permit adjusting the angle of the oscillating movement of the vertical shaft to slightly more or less than 90*, as desired, as well as for adjusting the orientation of the angle of oscillatory movement, without stopping the machinery.
