ABSTRACT:
A flexible connector for connecting adjacent ends of spaced apart, upper and lower conduits used in conveying particulate material, where one of the conduits regularly moves, is formed of a cloth-like tube whose upper and lower ends surround the conduits and are secured thereto by elasticized bands. A loose, cloth-like, tubular sleeve is arranged within the tube with its upper end secured to the upper end of the tube for surrounding the upper conduit with the tube upper end. The sleeve is otherwise unsecured to the tube and its lower end loosely extends beneath the tube and into the upper end of the lower conduit. A resilient, stiff band surrounds and is secured to the middle of the tube for maintaining the shape of the tube while the sleeve is free to move and yield under the impact of, and the venturi-like effect due to, the flow of particulate material from the upper conduit to the lower conduit through the connector.
