ABSTRACT:
A keeper for retaining opposite ends of a pair of idler rolls fixed within apertures in the first and second supports of a common bracket. Keeper is unitary rigid member including a planar body with a raised rib on its upper surface and a pair of shallow, substantially triangular legs depending therebelow. Such legs extend away from the body at an obtuse angle and the apex of each triangular leg is flattened slightly to form a run parallel to longitudinal dimension of the body so that legs can span the distance between the supports of the bracket and engage the wrench flats at the ends of a pair of idler rolls. Keeper is forced into locking position by simple manual tools, and once in position, the rib on the keeper is trapped between the opposite walls defining the apertures in the bracket and the reaction of the idler rolls presses on the legs of the keeper so that the keeper exhibits a self-captivating characteristic.
