  • Patent number: 4834940
    Abstract: Tooling and a method are provided for producing powder metal compacts in which a fine hole is provided through the compact without the need for secondary operations. A top punch and bottom punch are used in an opposing relationship and a stem is provided on the top punch to form the hole through the compact. A resilient member is placed upon the bottom punch opposite the stem. When powder metal is introduced into the die cavity of the press, the powder is compressed by pressing the first punch against the second punch. During this powder compaction process, the stem of the first punch will press through the powder until it engages and penetrates the resilient member. When the first punch and second punch are released, a powder metal compact is formed having a hole provided the entire length therethrough. Such a powder metal compact is especially designed for use as a wire-drawing die.

  • Patent number: 4790428
    Abstract: A conveyor belt guide apparatus is provided in which a guide roller is attached on either side of a conveyor belt and contacts the same. The guide roller is designed to rotate by the force of the conveyor belt when the conveyor belt moves off center. Spiral rings are positioned on the guide rollers in such a manner that the rings have a vertical pitch in the direction in which the conveyor belt causes the guide roller to rotate. When the conveyor belt attempts to climb up the guide roller, it engages the spiral rings and is forced back down. In this manner, the conveyor belt is prevented from climbing above the guide rollers and is adjusted back to its normal position.
