ABSTRACT:
The apparatus includes a sleeve which is attachable to a tool to be lowered into an uncased well bore. The sleeve has a roller mechanism connected in longitudinal relationship therewith so that the wheel is disposed beneath the tool as the tool is lowered into the well bore. The wheel has a slightly larger diameter than the maximum outer dimension of the sleeve so that the wheel will engage the surface of the uncased well bore and prevent the tool from becoming lodged on an indentation of the uncased well bore.
