ABSTRACT:
A body for sliding in a track, and a rotary barrel cam. One portion of the body has two legs defining a separation zone between them for divergent movement of them. They further define within the zone, a passage in the body, for receiving the barrel cam. The barrel cam is mounted in the passage for rotation, about an axis that is generally normal to one wall of the track.
The barrel cam and the body define between them an axial thrust cam for forcing part of the pivot shoe axially with respect to the axis, against an inner surface of the track when the barrel cam is rotated.
An axially slidable brake pad is located over the barrel cam for engaging the inner surface of the track when the barrel cam is rotated.
The barrel cam and the body also define between them a radial thrust cam for forcing a leg radially with respect to the axis against an inner surface of the track when the barrel cam is rotated.
The body is adapted for receiving external elements for urging the body along the track.
