Conveyor chain

A conveyor chain comprising:

• a plurality of side link assemblies and flight arm assemblies coupled together with universal connector assemblies to form an elongated chain;
• at least one flight arm assembly including a pair of opposing flight arms positioned on either side of the chain, the flight arms each comprising:
• an elongated body and an integral base formed with and extending from the integral base;
• a vertical sprocket opening formed in the integral base to extend vertically through the integral base, the vertical sprocket opening being configured for engaging a tooth of a drive sprocket to drive the flight arm;
• integral bases of the opposing flight arms configured to engage a respective tooth of a drive sprocket positioned on either side of the chain for driving the flight arm assembly on both sides of the chain;
• at least one side link assembly including a pair of opposing side straps positioned on either side of the chain, the side straps each comprising,
• a base;
• at least a pair of side strap bosses extending outwardly from the base and
• configured to engage a tooth of a drive sprocket to drive the side strap;
• side strap bosses of the opposing side straps configured to engage a respective tooth of a drive sprocket positioned on either side of the chain for driving the side link assembly on both sides of the chain;
• at least one universal connector assembly including:
• a universal pin;
• a universal link having an upper lip and a lower lip and corresponding vertical thru-holes configured to receive at least a portion of the universal pin, and a connecting portion extending between the upper lip and the lower lip and forming an opening there through, the connecting portion forming a horizontal bore;
• a connector link having a projecting member with a vertical bore configured to receive at least a portion of the universal pin, the projecting member being configured to be positioned between the upper lip and the lower lip of the universal link, and including horizontal bore extending laterally through the connector link;
• the universal pin coupling the connector link and universal link together to form the universal connector assembly;
• at least one of the universal link horizontal bore, the connector link vertical bore or the connector link horizontal bore being hardened with respect to the link.

• the elongated body including a plurality of apertures formed therein;
• urethane material formed over at least a portion of the elongated body and extending through the apertures;
• integral bases of the opposing flight arms configured to engage a respective tooth of a drive sprocket positioned on either side of the chain for driving the flight arm assembly on both sides of the chain;
• at least one side link assembly including a pair of opposing side straps positioned on either side of the chain, the side straps each comprising,
• a base;
• at least a pair of side strap bosses extending outwardly from the base and
• configured to engage a tooth of a drive sprocket to drive the side strap, each side strap including at least one opening extending through the base and at least one of the side strap bosses;
• side strap bosses of the opposing side straps configured to engage a respective tooth of a drive sprocket positioned on either side of the chain for driving the side link assembly on both sides of the chain.
