Abstract
A keyless mounting device has inner and outer tubular sleeves telescopically engaged. The confronting surfaces of the inner and outer sleeves are tapered so that relative axial displacement of the sleeve in one direction expands the outer surface of the outer sleeve and contracts the inner surface of the inner sleeve. Relative axial displacement in the other direction allows the outer surface to contract and the inner surface to expand. The inner and outer sleeves are threaded at one end and the free end of each sleeve adjacent the threads provides an annular abutment surface. An adjustor is provided to effect the relative axial displacement of the sleeves. The adjustor has one set of threads to engage the threads of the inner and an abutment surface to engage the abutment surface of the outer when the threads are tightened and second threads adapted to engage the threads of the outer and second abutment surface adapted to engage the abutment surface of the inner when loosening the sleeves. One form of the adjustor is a one-piece unit having a hexagonal form with threads at opposite ends so that the one-piece adjustor may be reversed and changed from loosening to tightening and vice versa. A second adjustor is shown having a knurled outer configuration to facilitate manual adjustment between tightening and loosening. A third adjustor is a two-piece adjustor having one piece adapted to perform the tightening operation and a second piece adapted to perform the loosening operation. In the illustrated embodiment of the two-piece adjustor, one of the pieces is provided with a cutout so that it may be removed from the shaft without need for sliding it off the end of the shaft.
