  • Torque limiting collar
    Patent number: 4577891
    Abstract: A torque limiting collar includes a support plate attached to a stationary support adjacent a fitting and a locking plate engaged with a nonmovable part of the fitting and bolted to the support plate. When the rotatable portion of the fitting is tightened against the nonmovable part, the torque is transmitted through the locking and support plates to the stationary support instead of being transmitted into the conduit connected to the nonmovable or rigid part of the fitting. The locking plate has an edge defined in the configuration of a segment of a socket pattern which matches and mates with the profile of the rigid part of the fitting.
