Abstract
A counterweight is connected to a driving shaft through a lost motion connection. The shaft is received in a bearing relationship in a fixed member. An axially extending portion of the counterweight coacts with the fixed member to define a pair of chambers which radially vary such that the chambers taper convergingly in a circumferential direction corresponding to the normal direction of rotation of the shaft. Cylindrical pins are located in the chambers and provide a jamming relationship between the counterweight and the fixed member when said shaft tends to rotate in a reverse direction.
