Abstract
A lightning resistant hydrological pulley comprising an insulator between a pulley body and an axle insert. The insulator is made of electrically non-conductive material, thereby denying lightning surges an electrical path from the pulley body to an axle disposed within the axle insert. Set screws angularly immobilize the pulley body relative to the insulator, and the insulator relative to the axle insert and relative to an axle disposed within the axle insert. In the preferred embodiment, the insulator is made of synthetic material such as white Delrin, and the pulley body and the axle insert are made of brass.
Claims17
A lightning resistant hydrological pulley comprising a pulley body having a boss insulator bore, an insulator disposed within said boss insulator bore, said insulator comprising an insulator axle insert bore, an axle insert disposed within said insulator axle insert bore, said axle insert comprising an axle insert bore, means of angularly immobilizing said pulley body relative to said insulator, and means of angularly immobilizing said insulator relative to said axle insert and relative to an axle disposed within said axle insert bore.
A lightning resistant hydrological pulley comprising a pulley body having a boss, said boss comprising a boss insulator bore, an insulator disposed within said boss insulator bore, said insulator comprising an insulator axle insert bore, an axle insert disposed within said insulator axle insert bore, and means of angularly immobilizing said insulator relative to said pulley body.
A lightning resistant hydrological pulley comprising a pulley body having a boss, said boss comprising a boss insulator bore, an insulator disposed within said boss insulator bore, said insulator comprising an insulator axle insert bore, and an axle insert disposed within said insulator axle insert bore, and means of angularly immobilizing said axle insert relative to said insulator.
