  • Starting apparatus for internal combustion engines
    Patent number: 6253722
    Abstract: A starting device has a rotary drive member that is operable by hand or power devices. The device has a detented or geared strip arranged to engage with a similarly detented or geared starting wheel. The teeth of these parts are designed to grab and lock with each other in the starting direction and to slip past each other in the opposite direction. Crimping, sticking and other failure modes of conventional wind up rope units are virtually eliminated. A more consistent pull is afforded owing to a constant radius interface with the starter wheel rather than a diminishing radius of the type delivered by a wound rope.
