  • Patent number: 8448781
    Abstract: A conveyor chain includes a plurality of chain links connected together in a chain, each including a pair of forward arms having a space therebetween and a rearward arm extending in a rearward direction. The forward arms of one link are configured to receive the rearward arm of an adjacent link to form a continuous chain. The rearward arm of each link extends a distance from the forward arms so that when adjacent links are coupled together, an engagement space is created between the forward arms of the links. The engagement space is configured to receive portions of sprockets that would engage the forward arms of the link for driving the chain.

    Abstract: An improved drag link chain is fabricated from a plurality of links joined together in articulated relationship for moving bulk material along a trough or other conveying surface. The links are made having an open end and a closed end. The closed end includes a barrel having a flat side for pushing material. The barrel is disposed within the closed end with its flat side facing inwardly from the closed end toward the open end of the link. The barrel has a rounded back side that seats on a tooth of a sprocket so that a joint of articulation is caused between an inner diameter of a bore of the barrel and an outer diameter of a pin that joins together open and closed ends of tandemly connected links to form an endless drag chain. The barrels of the links, when engaged by teeth of a sprocket are seated thereon with no relative rotation therebetween and thereby avoid excessive wear on the barrels and the teeth of the sprocket.
