The keeper spans the end of the handle and is provided with inturned tongues or flanges I adapted to enter longitudinally extending receiving channels 8 formed in the sides of the handle.

The body of the handle is cut away so that the exteriorfface 'oflthej keeper lies flush with the face of the handle and friction is relied upon to hold the keeper in any set position. Obviously. one can readily shift the keeper with his finger or thumb to a position overlying,; r-;clear of-the head of the pick. A keeper of this kind is very simple and inexpensive in construction' and re liable in use but of course any other means could be used for the purpose the -scopeof the;
