DEVICE IN CONNECTION WITH CENTRIFUGAL COUPLINGS

摘要

A centrifugal clutch having an internal drum surface on a driven member with friction shoe members displaceable on a driving member to and from said drum surface but normally drawn away therefrom by resilient means and each having an opening with a cam shaft extending therethrough, each cam shaft being rotatable in elongated openings in said driving member and having a lever extending towards said drum surface and another lever pivotally mounted on said clutch and positioned for engaging said first levers when desired to pivot said first levers from said drum surface and allow said resilient means to move said shoe members from said drum surface even when said driving member is rotating at a speed that normally would cause said shoe members, due to centrifugal force, to engage said drum surface.
