Abstract
In a conveyor chain and trolley assembly consisting of a chain center link having an open central portion through which the bases of a pair of trolley brackets extend, an interlocking connection is provided for preventing relative movement between the center link and trolley brackets. A pair of bosses are formed on the sides of the center link and project inwardly into the open central portion medially between the ends of the center link. Complimentary shaped recesses on the bases of the pair of trolley brackets are positioned in interlocking engagement with the pair of bosses by an attachment member which is mounted between and is connected to the bases of the pair of trolley brackets. In an alternative construction, only the attachment member extends through the open central portion of the center link and is provided with grooves engaged by the pair of bosses.
