  • Patent number: 4364452
    Abstract: Each feeder cylinder, in addition to opposite end feeder chambers, had intermediate chambers formed in the piston at opposite sides of the centerline thereof alternately in fluid communication with the feeder chambers of another of the feeder cylinders. Additionally, each feeder cylinder has a monitoring cylinder in flow communication with the feeder chambers thereof arranged such that when lubricant is forced from a feeder chamber of a particular feeder cylinder to the associated bearing, less than one-half of the lubricant received at that bearing is forced by back pressure to one of the monitoring chambers of the associated monitoring cylinder. Thus, for each of the opposite strokes of a feeder cylinder, one associated bearing of a pair receives a major quantity of lubricant and the other bearing of that pair a minor quantity of lubricant while the associated monitoring cylinder is forced through one of its alternate strokes in supplying the minor quantity of lubricant.

  • Patent number: 4362037
    Abstract: An upper die is movable by a ram downwardly against a lower die with the dies enclosing a hollow article such as a knobshell in die cavities thereof. RAM continued downward movement of the closed dies forces a piston connected to the lower die downwardly against hydraulic fluid of a containing cylinder forcing the hydraulic fluid internally of the knobshell through the neck thereof forming the knobshell outwardly against the die cavity surfaces. The piston size compared to the knobshell size automatically creates a reactive force reversely tending to maintain the dies closed greater than the internal knobshell forming force tending to separate the dies. After knobshell forming, reverse ram movement first relieves piston pressure against the hydraulic fluid and ultimately separates the dies with a knockout member being actuated to eject the formed knobshell.
