  • Patent number: 5190145
    Abstract: A multifunction return-way system for one or more chains in a conveyor system. U-shaped mounting clips, having U-shaped arm ends, are snapped onto cross members between frame portions of the conveyor system, and are shaped to have snapped therein wear strips that are oriented in serpentine manner as viewed from above. Portions of the wear strips are maintained spaced apart by spacers mounted onto the rods and by spacer pins that are provided on the mounting clips for association with each other or with side frames. The mounting clips are thus trapped in desired locations. Intermediate clips, or pinch clips, are provided to hold central regions of the wear strips close to each other, at regions where there are no cross members.
