Abstract
Abstract A combined turret positioner and hold-down clamp assembly at a glass pressing position of a turret-type glass pressing machine and including cooperatively mating male and female members associated with mold adaptors or supports, equally spaced apart about a peripheral portion of the machine turret, and also associated with an anvil at the glass pressing position, the mating members each embodying a vertical cross-sectional configuration of an inverted truncated isoceles triangle and there being one such member associated with each mold adaptor or support and its associated mold with one of the members being similarly precisely positioned on the turret in relation to each of the respectively associated mold adaptors and molds carried thereby. Motor means at the pressing position for successively actuating the mating member at that position into mating relationship with each successive mating one of the members as each respective mold adaptor and mold is successively moved to the pressing position, and means selectively energizing the motor means to start each mating actuation as the leading edge of each respective mating member associated with each respective mold adaptor and mold is moved into vertical alignment with the corresponding edge of the mating member at the pressing position, the mating actuation continuing until the turret is actuated into firm contact with the anvil at the pressing position. In a preferred embodiment of the invention the male and female mating members each embody a vertical crosssectional configuration of an inverted truncated right triangle with the right angle of each configuration being the truncated apex angle of such configuration.

Claim 1
Independent Claim
365 words
In combination with a rotatable turret of a turret-type glass pressing machine having a circular row of mold adaptors equally spaced apart about a peripheral portion thereof with means adapted to successively index said adaptors to each of a plurality of positions including a glass pressing position at which an anvil is arranged under and adjacent to said turret in close proximity thereto, a combined turret positioner and holddown clamp assembly for said glass pressing position, such assembly comprising; A. circular rail means including a plurality of similar arcuate and slightly spaced apart rail segments extending about said turret adjacent the outer periphery thereof and equal in number to said mold adaptors, each such rail segment embodying in the upper surface thereof a channel, each such channel being congruent with the others and each having a vertical crosssectional configuration of an inverted truncated isoceles triangle and each rail segment being similarly located adjacent an associated one of said mold adaptors with the channel in the respective segment precisely positioned in relation to the respectively associated adaptor; B. a vertically actuable wedge member at said glass pressing position, said wedge member including a portion having a crosssectional configuration corresponding to said configuration of each said channel and such wedge portion being normally positioned above said rail means in close proximity thereto; C. motor means for actuating said wedge member downwardly and said wedge portion into each said channel as each respective rail segment is indexed to said glass pressing position and for thereafter actuating such wedge portion out of each such channel; and D. control means for energizing said motor means in a first mode to start said downward actuation of said wedge member as the leading upper edge of each respective channel is moved vertically below the corresponding lower edge of the wedge portion of such wedge member and to continue such downward actuation until the ends of the wedge portion are in firm contact with the ends of the respective channel and said turret is actuated into firm contact with said anvil, and for thereafter energizing said motor means in a second mode to actuate said wedge portion upwardly out of each respective channel.
