ABSTRACT:
This relates to a special endless conveyor chain particularly adapted to carry fixtures which are to be readily removable and replaceable on the conveyor chain. In order to accomplish this, the pins which connect together the links of a conventional conveyor chain are elongated above the conveyor chain for reception in bores within an associated fixture. The conveyor chain is formed of elongated links and shorter links with the length of the elongated links being in accordance with the general dimensions of a fixture longitudinally of the conveyor chain. Each upper one of the elongated links is provided with a flat upper surface so as to provide a supporting surface for a fixture to be mounted thereon. Instead of the usual strap-like configuration, each upper elongated link is preferably provided with an enlarged central portion which may be circular in outline to provide an adequate seat for an associated fixture. A special sprocket may be provided for the conveyor chain with the sprocket having circumferentially spaced teeth for reception between customary rollers of the conveyor chain and with the sprocket further having between each pair of teeth a radially outwardly projection for projecting between elongated links of the conveyor chain with the sprocket projection being in supporting relation with respect to an associated upper elongated link whereby a loading placed on a fixture carried by the conveyor chain is first transmitted to an associated upper elongated link and through that link to the underlying sprocket projection.
