Century Dictionary and Cyclopedia
- n. A pin-chain of the link-belt type having a loose roller on each pin that joins the links. The roller serves to give a rolling contact with the sprocket-wheel of a conveyer and as a bearing to support the chain when it is drawn over an uneven surface, as in a car-haul.
“Engineering details even extend to a roller-chain cam-drive sprocket lined with rubber for quiet operation.”
