Abstract

1517193 Overload couplings C VAN DER LELY NV 2 July 1975 [5 July 1974] 46700/77 Divided out of 1517192 Heading A1B A shear pin 22 connecting the tine support 11 to a projection 8 on a driven shaft 1 for rotation, is advanced after fracture by a spring 24 to be entrained in a recess 19 in the side of the projection 8 so that rotation of the tine support 11 is resumed. The sheared-off end of the pin 22 may be pushed from sleeve 18 via opening 17, and the pin 22 re-engaged in the sleeve 18.
