Abstract: An invert cylinder mechanism for a glass container forming machine of the I.S. type, the invert cylinder mechanism having a piston that is moveable along a rectilinear path between inner and outer positions within an annular housing to cause a cylinder rod attached to the piston to extend from said annular housing and to then retract back into said annular housing. A shock absorber is positioned within a recess of the annular housing with its longitudinal central axis spaced from and extending parallel to the longitudinal central axis of the rod. The shock absorber is engaged by the piston as the piston reaches its outer position to absorb inertial loads as the piston decelerates to a stop at its outer position. The recess has an opening out of alignment with the longitudinal central axis of the installed shock absorber, and the shock absorber is removable through the opening along its longitudinal central axis after first pivoting the shock absorber with respect to the longitudinal central axis of the rod.

Abstract: A shuttle type sweepout mechanism is described wherein the 90.degree. sweepout that consists of rotary head driven through an arc is mounted on a support that is translated in the direction of the moving conveyor. With the sweepout head capable of being rotated and translated makes it feasible to have an array of deadplates that are in alignment but at different distances from a pair of parallel conveyors that transport the ware to the lehr.

Abstract: There is herein disclosed a take-out arm mechanism for a glass forming machine particularly suited for the simultaneous handling of four or more containers wherein the arm is provided with an integrally molded and formed counterweight carried thereby to counteract the weight and mass of four take-out tongs, holders and attendant mechanisms. In addition, a novel tensioning means is provided for maintaining an adjustable, constant tension in an endless chain which extends between a pair of sprockets carried within the take-out arm. The sprockets and the chain together form, in essence, a parallel linkage mechanism which maintains the tong holder end of the take-out arm vertical relative to the movement of the arm through 180.degree. about the axis of the fixed spindle.

Abstract: This invention relates to conveyor systems and more particularly to article handling or positioning mechanisms for serially conveying or transporting hot glass containers between two or more work stations and into precise locations on alignment. The systems utilize heat-resistant fingers or arms to provide spaced-apart modules for retaining the glass articles, the fingers or arms being readily replaceable and reversible in ready-releasing locking arrangement.

Abstract: Each section of a multi-section glass forming machine contains a plurality of mechanisms for moving functional members in sequence for forming gobs into glass containers and for sweeping the containers from a cooling dead plate to a moving machine conveyor.A plurality of reversible, electric motors are provided for each section to operate the rotation of the sweepout mechanism and for operating the other mechanisms, namely, the parison mold opening and closing mechanism, the funnel operating mechanism, the baffle operating mechanism, the invert arm operating mechanism, the blow mold operating mechanism, the blowhead operating mechanism and the take-out mechanism. Each motor is coupled directly to the drive shaft of the mechanism and the rotation of each motor is controlled by a programmable controller which permits the adjustment of the timing and velocity during machine operation of each motor independently of the other electric motors.

Abstract: Apparatus for taking newly formed glass containers from a blow mold and transferring the containers to a dead plate wherein the take-out tongs for engaging the containers are mounted on a pair of holders that are pivoted like scissors relative to each other. A piston motor is pneumatically driven in one direction to cause the tongs and holders to close, and a spring, urging the piston in the opposite direction effects the opening of the tongs. When the tongs are open, the connection between the piston rod and the holders is a toggle linkage when the links are in a straight line preventing "winking" movement of the tongs toward closing by the fact of the toggle arrangement. Thus machine air closes the tongs and a fairly light spring force opens them.

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.

Abstract: Apparatus for moving newly formed glass containers from a cooling dead plate to a moving machine conveyor in which the ware is engagedf by a finger, with the finger being generally horizontal and engageable with the container at a point on its sidewall which best suits the moving of the container by a sliding motion. The finger, or fingers in the case of plural containers being simultaneously moved, is moved through an arc approximately 90.degree. with respect to its vertical axis, moving the containers from the dead plate to the conveyor and then the finger is retracted out of contact with the containers on the conveyor. The cylinder for extending and retracting the fingers is mounted on the upper end of a vertical shaft, the shaft being oscillated through approximately 90.degree.. In the drive mechanism for the shaft, a sprocket-carrying housing surrounding the shaft is provided with an internally contained, flat spiral spring which connnects the housing to a coaxially positioned sleeve.

The finger, or fingers in the case of plural containers being simultaneously moved, is moved through an arc approximately 90.degree. with respect to its vertical axis, moving the containers from the dead plate to the conveyor and then the finger is retracted out of contact with the containers on the conveyor. After retraction, the finger-mounting mechanism which takes the form of a generally horizontally disposed cylinder is moved back through 90.degree. to a position opposite the position of a dead plate where the finger is then again moved outward and rotated about the axis of the cylinder mounting. In this fashion the containers are moved onto the conveyor.
