摘要： A wear ring seal construction for a carrier used in a pneumatic tube system, particularly a carrier of the type having a pair of wear rings surrounding the carrier body spaced from each other and from the ends of the carrier. The wear rings each are formed of a plurality of ring layers or laminations of a special material which flexes easily to accommodate out-of-roundness of the tube cross section, and indentations or sharp projections in the interior of the tube wall. The ring layers have alternately large and small diameters and different thicknesses and the arrangement of ring layers preferably is symmetrical about a center plane perpendicular to the ring axis. The wear rings are replaceable and have a minimum contact with the tube inner surface during travel through the tube while providing an efficient seal. Further, the minimum surface contact between wear ring and tube results in a miminum area on the edges of the seal rings for the collection of material which can soil the hands of a user manipulating the carrier when removed from the tube.

摘要： A closure construction for an open end of a generally tubular material-conveying carrier for a pneumatic tube system, especially adapted for banking service transactions. The end closure, preferably is formed of lightweight molded plastic components, and is pivotally mounted for smooth and ready lateral movement across an open end of the carrier body between fully closed and fully open positions. The end closure side wall is tapered enabling the carrier to move through pneumatic tube bends having reduced radii. An inturned flange is formed on the end closure and engages an outturned flange on the carrier body when in closed position preventing axial movement of the end closure away from the carrier body. A spring-biased toggle-connected mechanism is contained in a cavity formed within the end closure to urge and hold the closure in either fully closed or fully open position.
