  • Improvements in or relating to locking devices for rotary bearings
    Patent number: 4183589
    Abstract: A device, especially for the bearings of idler rollers of underground coal conveyors in collieries, to lock the two halves of a bearing against further rotation when the bearing overheats. Overheating causes a fusible plug, mounted on one half of the bearing, to melt and release a catch member which engages with an abutment on the other half. The plug may be designed so that when it has once fused so as to lock the two halves, it still prevents them from resuming mutual rotation even if it solidifies again.
