My device relates to a device to clean sheaves, such as those used in the operation of elevators. A particular application of my device is as a sheave cleaning tool. The present invention, the sheave cleaning tool, comprises of a mounting plate and a blade plate attached by a hinge. A handle is welded to the blade plate to enable the the operator to raise and lower the blade, altering the level of pressure of the blade, applied to the sheave, without the operator having any contact with the blade or sheave. When this pressure is applied, the blade is lowered into the groove of the sheave, cutting and scraping away hardened rope tar that has been packed into the grooves of the sheave which guide the cables around the sheave. The blade itself is cylindrical and cut on an angle to form a point which fits into the grooves of the sheave. A cloth attachment may be fitted over the blade to apply cleaning solutions after the device has been used to remove hardened rope tar from the grooves of the sheave. The present invention has three safety features which may be added. The first safety feature consists of a threaded rod which is attached to the adjustable mounting plate, runs through the blade plate and is bolted on the underside of the blade plate. The second safety feature consists of a spring-back mechanism which automatically retracts the blade when not in operation. The third safety feature may be added to the design of the blade itself. The blade may be designed to pivot and lock to ensure the retraction of the blade during reverse movement of the sheave.
