A clamp member will clamp a bag to each frame so that it may be open when the V is present. A torsion spring biases the frames toward one parallel position and away from the other. A pair torsion springs connecting the frame provides a convenient hinge.

  • Patent number: 4922688
    Abstract: In a load transporting conveyor of the type which has a plurality of load confining compartments located thereon which are transported by the conveyor along a load transporting path, there is provided a load settling mechanism. The load settling mechanism includes a load support platform which forms a bottom wall of each compartment. Resilient suspension members support the bottom wall with respect to the conveyor such that it is free to vibrate with respect to the conveyor. A vibration activator mechanism is located along the load transporting path so as to engage successive load support platforms as they are transported along the load transporting path to cause the load support platform to vibrate to thereby vibrate any load which is located thereon to cause the load to settle into the load confining compartment.
