ABSTRACT:
In glassware forming apparatus the reciprocation of a transfer carriage between two operating positions is effected by a cylinder and piston device in which the traverse of the piston is progressively cushioned at the ends of the piston stroke. Members, which are slidably mounted in the piston and protrude from it, close exhaust outlets in an end wall of the cylinder when the piston is at different predetermined distances from the end wall, and these members are positioned in the piston by the action of the end wall for similarly co-operating with corresponding exhaust outlets in the opposite end wall of the cylinder.
