Abstract

An accumulator conveyor having an endless driven propelling member has a vertically adjustable support for said propelling member. The support has a stationary lower member and a vertically movable upper member divided into a plurality of segments arranged in tandem with two or more actuators supporting each segment of the upper member on said lower member. Each actuator has a hinged connection to both the upper and lower members and means to limit variation in the spacing between the plates. An expander is mounted on each actuator for forcibly separating the upper plate and actuator and lifting the upper plate as it pivots the actuator about its hinged connection to both the upper and lower plates. Separating the plates lifts the propelling member into conveying mode.
