  • Safety restraint for brake actuators
    Patent number: 4565120
    Abstract: A safety restraint limiting the separation of brake actuator housings containing powerful compression springs. The restraint consists of a sheet metal body having a notch receiving the housing flanges, the notch being of sufficient dimension to permit partial separation of the housing flanges upon release of the flange clamp band, and the flange and restraint include engaging complementary surfaces which produce an inward force on the restraint when the restraint is subjected to axial spring forces thereby retaining the restraint notch in alignment with the housing flanges to limit axial separation thereof.
