Abstract
The take-out mechanism on a glass container forming machine is operated by the vertical reciprocation of a fluid motor. The movement of the tongs into position to grasp a new container is controlled so that the tong arm which is swinging through an arc of 180.degree. degrees, is cushioned in its final movement so as to avoid excessive vibration of the mechanism. The pressure introduced into the motor for moving the tong arm into position over the dead plate is also connected to a second piston which is spring-biased in relation to the piston rod of the motor. When the tong arm has completed its movement and released the container at the dead plate, the pressure is discontinued at both the motor and the second piston which results in the rod of the second piston actuating the motor rod to cause the tongs to be lifted a predetermined amount. Two racks are driven by the motor through a common pinion and the racks are decelerated at the ends of their travel which corresponds to movement of the tong arms into their two final positions.
