Title: Securing means for machine parts

Abstract: Means are disclosed for securing together a first, U-shaped member and a second member received within the first member. In the preferred embodiment, the second member is a holder for a mineral cutter pick and the U-shaped member is formed on a drum or cutter chain of a mining machine. The means comprise registering bores in the legs of the U-shaped member and in the second member, one of the members being formed with a recess extending transversely from the bore therein. A hollow cross pin is received within the bores and a locking pin is driven through a transverse bore in the cross pin to extend into said recess. The cross pin has a length equal to or less than said bores in registration, and part of its internal surface is provided with a screw thread.
