One of Johnson's notable inventions is an apparatus for the removal of vault lids and other heavy covers. This tool is designed to lift and remove heavy lids, such as manhole covers, with ease. It features an elongate lever with a handgrip at the upper end and a pivot head at the lower end. The pivot head is equipped with wheels that provide a pivot axis, while a hook is mounted in front of the pivot axis and a footplate is located behind it. The hook is inserted into an opening in the lid, allowing the operator to lift and remove the lid by pulling back on the lever and stepping down on the footplate. After removal, the lid can be transported by rolling the assembly over the ground using the wheels. This invention significantly reduces strain and the risk of injury for the operator.
