Push plate assembly for large diameter glassware

Claim 1

In a 90* pushout mechanism for transferring newly formed glassware articles from a dead plate of a glassware forming machine to a conveyor, said 90* pushout mechanism including: a. a fluid motor having a housing, an extendible member therein, and means for moving said extendible member cyclically through forward extension and rearward retraction strokes; b. means for rotating cyclically said housing and said extendible member through an angle of approximately 90* in a substantially horizontal plane in coordinated relation with the cyclical extension and retraction strokes of said extendible member; c. a push plate mounted in lateral position at the forward end of said extendible member; d. said push plate having an extension which projects laterally beyond the housing of said extendible member; e. a rotatable shaft carried on said lateral extension of said push plate; f. an elongated push finger mounted on said rotatable shaft; g. means for moving pivotally said push finger through an angle of approximately 90* from a horizontal forward position to a vertical upward position during the retraction stroke of said extendible member, said means comprising: g-1. a cam lever fixed to said shaft in said lateral extension of said push plate; g-2. spring bias means for assisting said cam lever toward a generally horizontal position rearwardly toward said housing; g-3. a cam roller adjustably mounted on the side of said housing in the vertical plane of said cam lever; g-4. said cam roller being adapted to be engaged by said horizontally disposed rearwardly extending cam lever during the retraction stroke of said extendible member to force said cam lever downwardly toward vertical position, thereby to rotate said shaft through approximately 90*, thereby to raise said push finger from a forward horizontal to an upward vertical position.
