Abstract: A roller made of a synthetic resin, used for a belt-conveyor, by means of utilizing insert-forming injection molding, placing a thin-walled metallic housing for containing a roller bearing therein, at the innermost boss portion, for concentrically forming a roller body integrally with the metallic housing. The inner race of the bearing is press-fitted onto the roller shaft, and the outer race thereof is press-fitted inside the metallic housing. A roller of such a construction will resist or absorb most of the inherently large thermal expansion and contraction of a synthetic resin made article, and thus enables the life of the resin made rollers to be elongated far beyond expectation.

Abstract: A roller made of a synthetic resin, used for supporting a conveyor belt, possesses an anti-electrostatic-charge capability. Utilizing insert-forming injection molding, a conveyor carrier roller body is integrally formed concentrically about a thin walled metallic housing containing a rotary bearing assembly therein at the innermost position for concentrically forming a conveyor carrier roller body integrally with the metallic housing. The inner race of the bearing is force-fitted onto the roller shaft and the outer race of the bearing is force-fitted inside the metallic housing. A roller of such a construction will readily discharge the static electricity charged on the surface of the roller by conducting it to ground through a snap ring (fitted in a circular groove formed inside of the boss portion of the roller), the housing, the bearing, and the shaft. The snap ring positioned adjacent the electricity charging place functions like a lightening conductor through the point-discharging.

Abstract: The invention is a unique connector for joining the juxtaposed ends of the shafts of two adjacent conveyor idler rolls. The shaft ends are provided with diametrically extending pivots.

One clevis loopingly or pivotably engages the pivots attached to one idler shaft, and the other clevis similarly engages the perpendicularly aligned pivots attached to the other shaft. In one embodiment, a trunnion nut having colinearly extending pivot stubs and a threaded central opening, is screwed onto the end of each shaft. Optionally, a flexible grease tube can be passed from one shaft end through the connector to the other shaft end to provide flow-through lubrication capability.

Abstract: Each end of a catenary carrier for an endless conveyor belt is supported by a quick release mechanism operable to drop the catenary rollers out of operation. The quick release mechanism includes a link which has an elongated slot wth an enlarged annular end portion. Supports at opposite ends of the catenary carrier carry a rotatable support pin for the link which has a head portion and a neck portion. The neck portion is annular except for two flats formed on radially opposite sides thereof. When the neck of the pin is disposed in the annular end portion of the slot, the link will be locked against movement relative to the pin in the direction toward the carrier if the flats are transverse to the slot. When the support pin is rotated 90.degree. to present the narrow width of the neck in alignment with the slot, the weight of the carrier will cause the link to move relative to the pin whereby the neck of the pin will be disposed in the opposite end of the slot from said annular portion.

Abstract: A plurality of troughing rolls, that are suspended in a chain-like manner between opposite side frame members of a conveyor, support a conveyor belt so that the transverse cross-section of the belt defines a trough. The troughing rolls that are located adjacent each side of the conveyor belt are axially inclined in opposite directions. At least one arm is pivotally mounted on the frame and attached to the adjacent end of an inclined troughing roll. A locking pin is provided for retaining the arm in a first position where the troughing rolls support the conveyor belt. The locking pin can be readily moved to release the arm for pivoting to a second position where the troughing rolls are clear of the belt. The arm is mounted to pivot in a plane that is generally parallel to the adjacent inclined side edge of the belt. This plane is substantially the same plane in which extends the line of force that is applied to the arm by the troughing rolls in a belt supporting position.
