Many Pickering governors had a spring loaded trip device to close the governor in the event of a mishap . This was often attached to a cord which ran to wherever it could be reached by those using the machinery . Known in the States , I believe , as ' The Sawyers Lever ' . The ratchet parts are often to be seen on governors .
A refinement of this was a weighted pulley on a swinging arm . The pulley ran on the back of the governor pulley , and if that belt broke or malfunctioned , then the pulley dropped and a lever from its arm tripped the ratchet and closed the governor . Very effective , and a good reason to use a Pickering .
