ABSTRACT:
A new and improved multi position bottle guide assembly for bottles suspended by a neck ring and conveyed by pneumatic power. The bottle guide assembly includes a pair of elongated guide rails positioned along the path of travel of a bottle which is pneumatically conveyed while supported by a neck ring. The rails are adapted to be in proximity to the sides of the bottle on opposite sides of its path of travel to preclude lateral movement. Further included are support mechanisms for the rails located at the ends of the rails. Also included are a plurality of rods for supporting the rails. Each rod has coupling mechanisms for the support mechanism at a first end and a piston at the second end. A block for each rod has a bore of a diameter essentially that of the diameter of its piston and extends through the block with its axis in alignment with the axis of the rod. Further included are a pair of axially spaced pneumatic ports extending through the block in a direction perpendicular to the axis of the bore and on opposite sides of the piston whereby when pressurized air is introduced through the port adjacent to the rail the piston moves away from the rail to accommodate larger bottles and when pressurized air is introduced into the port remote from the rail, the piston moves towards the rail to accommodate smaller bottles.
