A retainer arrangement for a stationary shaft, rod or the like for retaining the shaft against upward movement in an upwardly open recess or slot of a support bracket, and the combination of the retainer with the shaft and with the support bracket. The retainer arrangement comprises a retention spring clip which encircles a substantial portion, such as 270.degree., of the shaft periphery contiguous the supported end of the shaft. The upper portion of the retention spring clip is formed to include opposite laterally spaced axially extending lugs which are adapted to snap each into a corresponding retention groove carried by the respective opposite recess-bounding walls of the support bracket when the shaft is seated in the upwardly open recess or slot of the support bracket. With the lugs of the retention spring clip engaged with the oppositely disposed retention grooves of the support bracket, the lugs are in axially overlying relation to oppositely disposed upper surface portions of the shaft, whereby to prevent upward movement of the shaft out of its seated position.

Shaft retainer arrangement

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. This action drops the caternary rollers from their supporting relationship with the conveyor belt. The opposite end of the slot is enlarged to permit the link to be removed from the head end of the pin.
