Abstract

In pneumatic conveying systems, telescoping joints are often employed to connect a fixed component with a movable component. Employment of conventional telescoping joints results in an uneven inner surface. Such has deleterious effects on carriers passing through it. The drawing shows a substantially air tight slip joint for a carrier transport tube. It comprises telescoping cylindrical outer sections and two sets of four interlocking finger s arranged to form a rectangular inner channel. As the device is extended the outer telescoping cylindrical sections prevent air loss. The interlocking fingers provide the extended carrier channel of rectangular shape. The free ends of the fingers flair outward to eliminate any projections into the channel area that might obstruct carrier movement.
