Latest Patents

Luther E Johnson holds a patent for the "Self Aligning Test Grip." This innovative tensile test grip is designed to hold a specimen securely while allowing for swiveling alignment of the pullrod and piston head. The device features a pullrod mounted in an annular bore, which carries a piston head that fits within a piston chamber. Both components are sealed on their outer surfaces, creating an enclosed chamber for hydraulic fluid. This design permits the pullrod and piston head to shift relative to the housing, providing self-alignment during tensile loads. Additionally, spherical seats can be locked together after initial alignment to facilitate compression testing.
