Abstract
A sprocket rotatable about a vertical axis and engaging a flexible roller chain having a sagging oncoming flight has a sloped portion on the upper side of each tooth near the forwardly moving edge thereof to facilitate initial engagement with the underside of the upper link plate of an oncoming sagging chain link and to lift the link plate up onto an adjacent flat horizontal surface near the tooth root whereby the chain link is firmly supported horizontally while engaged with the tooth. Preferably, each tooth has two oppositely sloped surfaces defining sloped edges and a commonly usable flat surface on its upper and lower sides so that the sprocket can be mounted for rotation in either direction regardless of which side faces upward.
