Abstract
An escapement is provided for use in conjunction with a conveyor having a frame which defines a plane on which articles are conveyed along a predetermined direction of movement. The escapement includes a housing which is pivotally secured to the conveyor frame about a first axis which is perpendicular to the predetermined direction of movement of articles on the conveyor. The housing includes a portion which is radially spaced from the first axis while a resilient shock absorber is disposed between the housing portion and the conveyor frame. A stop bar is movably mounted to the housing between an engage and a release position. In the engage position, one end of the stop bar is positioned above the conveyor plane so that, with the stop bar in the engage position, the stop bar prevents the passage of articles on the conveyor past the stop bar. Conversely, in its release position, the stop bar is retracted below the conveyor plane thus releasing articles for further movement on the conveyor past the stop bar.
