ABSTRACT:
A shear pin coupling comprises two coupling parts which are normally interconnected by a shear pin. Upon overload, the shear pin fractures and the parts can rotated relative to one another. After fracture, the shear pin is advanced to re-interconnect the coupling parts by a spring-loaded plunger. The shear pin and the plunger are shaped to prevent displacement of the shear pin in a direction other than its lengthwise direction. The end of the pin may, for example, be conical for this purpose.
