ABSTRACT:
A lehr loader (20) for transferring a line of freshly formed glass containers (C) on a cross-conveyor (XC) transversely of the cross-conveyor into an annealing lehr (L). The lehr loader has a superimposed stack of three carriages (48, 76, 94), the lowermost carriage (48) being supported on a frame (22) and being movable longitudinally in a horizontal plane with respect to the frame toward and away from the lehr. The intermediate carriage (76) is supported on the lowermost carriage (48) and is movable longitudinally with the lowermost carriage and is movable laterally in a horizontal plane with respect to the lowermost carriage. The uppermost carriage (94) is supported on the intermediate carriage (76) and is movable horizontally with the intermediate carriage and vertically with respect to the intermediate carriage. The uppermost carriage carries a pusher bar (120) for transferring glass containers (C) from the cross-conveyor (XC) into the lehr (L) upon motion of the lowermost carriage (48) toward the lehr. An air cooled support bar (246) surrounded by a pair of radiation shields (256, 258) is provided to prevent the support bar from being distorted due to the high temperature environment in which it must operate.
