ABSTRACT:
A pneumatic tube conveyor system including tubing of rectangular cross-section with both elevational and lateral bends. The carriers are generally rectangular in outline with a pair of generally cylindrical fore and aft transverse members interconnected by a narrower and thinner intermediate section. The ends of the transverse members are curved on radii equal to one-half the longer inside dimension of the tubing and the tops and bottoms are curved on radii equal to one-half the smaller dimensions so that diametrically opposite sides are in contact with the tubing walls as they negotiate bends.
