Abstract: A reel is formed of a plastic molded huband and side, disk-like flanges. The hub is made of thin-wall, cylindrical rings that are arranged end-to-end, and the flanges are made of two or more separate radial sections having radially oriented, overlapped edges that fasten together. Removable mechanical fasteners extend through passageways formed in the hub rings and through the flanges for fastening them together. The width of the reel may be varied by changing the number of rings. The diameters of the flange may be varied by blocking off the outer portions of the mold in which the flask sections are molded to remove selected amounts of the peripheral portions of the sections for reducing the flange diameter. The hub rings and flange sections are interchangeable with like rings and sections for repair or reduced inventory purposes.

Abstract: A pallet system formed of a unitary, plastic molded, grid-like base made of intersecting, spaced apart, longitudinal and transverse strips, whose upper edges define a carrying surface. The lower edges of at least some of the longitudinal strips are generally coplanar to form a skid-like base support surface that may be positioned upon a conveyor. The lower edges of the remaining strips are recessed relative to the plane of the support surface. A unitary, plastic molded nest, having integral upper formations shaped to receive corresponding portions of supported articles, is rested upon the base and overlaps some of the openings in the grid-like base. Integral projections on the nest extend into their adjacent overlapped openings and engage the sides of adjacent strips for accurately positioning the nest relative to the base.

Abstract: A plastic conveyor trolley for an inverted T-bar monorail conveyor track is provided. The conveyor trolley comprises a pair of upper track-supported wheels and pairs of lower wheels engageable with and rotatable at times upon the underside surfaces of the track, the upper wheels being rotatably mounted on stub axles secured to the upper portions of the trolley arms, the lower wheels being rotatably mounted on bearing portions integrally formed in intermediate portions of the trolley arms, and a pendant member secured to and between the lower portions of the trolley arms. The lower wheels lie in a plane below and substantially parallel with the plane of the upper wheels.

Abstract: A plastic arcuate turn wheel structure for a plastic monorail conveyor structure is disclosed. The turn wheel structure is driven by a plastic chain drive and comprises a supporting structural framework, an arcuate inverted T-bar track section, a disc supporting plate, a turn wheel which is either an idler or a driven wheel, an axial bearing hub for said wheel, and a bearing thrust collar for said wheel.
