Improvement on Abegg's Jan. 11, 1921 patent no. 1,365,071 for firmly attaching sockets to handles. In one form the clamping screw to attach handle and socket is placed inside the bore of the socket rather than being reached through a hole in the side of the socket. In another form, a wedge clamps the split shank to the socket.

Subsequent Abegg patent no. 1,422,067 moves closer to a typical spring / ball retainer attaching sockets to shanks.
