ABSTRACT:
A clevis having a pulley rotatably mounted between its outer ends has a bight or closed inner end of uniform thickness curved around a segment of a cylindrical surface with its axis parallel to the plane of rotation of the pulley, and spaced from the surface of the pulley. A retaining clamp bar has flat ends attachable to a mounting surface, and a center portion off-set upwardly from the plane of the ends by a distance no greater than the thickness of the bight of the clevis. The off-set center portion is curved transversely upwardly about a segment of a cylindrical surface substantially coincident with the axis of curvature of the bight of the clevis when the clamp bar is arranged through the clevis and secured at its ends to a supporting surface. The periphery of the pulley is concavely curved and spaced at its center from the bight of the clevis.
