1009 forum posts 305 photos	I would not thought that it is part of a centrifugal clutch mechanism as they do not have any means of attaching a spring to hold it in to return them to the resting position when RPM lowers

1186 forum posts 11 photos	I have seen very similar, but with the boss on the outside of the curve, in a lever-operated lathe spindle-mounted collet chuck. The closing ring, to which the lever is attached, remains stationary and only moves forward or backward when operating the lever. The bronze slippers run in a groove in the part of the closing ring that rotates with the chuck. I must stress that the ones I have seen are inside out compared to the ones you show, so the above could be highly misleading.
