Abstract
A mechanism useful as a slip clutch or brake which comprises a housing member having a shaft affixed thereto and extending from one end thereof and a ball at the other end thereof having a second shaft extending therefrom outwardly of the housing. The housing has a partial end wall with an opening therethrough for the second shaft and a friction material having a partially spherical surface in the housing and positioned against the partial end wall. The ball is seated against the partially spherical surface of the friction material and drives the housing therethrough, but will slip when a predetermined torque is exceeded. The ball is biased into engagement with the friction material whereby when one of the shafts is rotated, the other is driven through frictional engagement of the ball and the friction material. Where the mechanism is utilized as a brake, the shaft on the housing may be eliminated.
