ABSTRACT OF THE DISCLOSURE An improvement is provided in an adjustable pulley con- struction. The adjustable pulley construction includes a first disc having at least one belt-engaging surface and having a centrally located internally threaded annular hub, and a second disc defining at least one belt-engaging surface and having a centrally located annular externally threaded axle, the annular hub of the first disc being coaxially and threadedly connected to the axle of the second disc and being axially movable relative thereto. The belt-engaging surfaces are positioned in facing relationship so that a pulley belt can be located therebetween. The improvement is in the form of means for securing the hub to the axle thereby to maintain a desired spaced relationship between the belt-engaging surfaces. The securing means includes a transverse threaded bore disposed within the hub and a set screw received in the bore. A longitudinal keyway recess is provided in the hub communicating with the threaded bore. A keyway land is provided on the axle adapted to be located in line with the set screw. A generally H-shaped key is positioned within the keyway recess in the hub and the keyway land of the axle, so that one surface of the key engages keyway recess and the other surface engages the keyway land, with one arm of the "H" projecting beyond the outside face of the hub, and the other arm preferably projecting into a recess in the hub. In this way, the key defines a clamping base for engagement with the set screw, turning of the set screw operating to move the end of the set screw relative to the key to provide a frictional clamping action of the key to the keyway land. In addition, the protrusion of the arms of the "H" prevents accidental loosening of the disc on the axle should the set screw become loosened.
