ABSTRACT:
A cutter bit mounting lug, a base member for mounting the lug to the driven element of a mining machine or the like and retaining means to prevent undesired disengagement of the lug from its base member. The lug and base member are so configured as to have a wedging engagement therebetween. The retaining means is separate from the lug and is so positioned with respect thereto as to be installable after the mounting of the lug on its base member and so as to be free of the resultant cutting forces sustained by the lug and the base member.
