  • Patent number: 4981404
    Abstract: For anchoring heavy machinery to foundations, previously tensioned stress-level indicating bolt connectors are provided. In a top axial cavity of the connector, threads are provided to mount an angularly adjustable stress-level indicating pin. In use, when the design tension stress level is reached and the connector thereby extended, angular freedom or restraint of the gaging pin indicates that the pre-set stress has been reached or exceeded. Indicia angularly arranged on the connector end facilitate adjustment of the pin to provide upper or lower stress levels.

  • Patent number: 4784364
    Abstract: For supporting heat and vibration producing machinery on grouted foundations, high-strength plastic chock halves, which may be glass-polyester laminates, are used beneath machinery conventional steel sole plates resting on conventional plastic grout. The plastic material is characterized by a greater flexibility and much lesser thermal conductivity than steel, so they serve as barriers to the transmission of heat, while their flexible resiliency protects the foundation from vibrations attendant to operation of the machinery so supported. Leveling steel shims inserted between the chock halves do not impair the uniformity of the flexible resiliency they afford at each support point. Fretting wear of the machinery bed plates appears to be completely eliminated.
