ABSTRACT:
A chain drive mechanism has spaced sprockets about which is trained an endless chain. A traveling chain is disposed radially inward of the endless chain and encircles one or the other of the sprockets during power transmission. The traveling chain is transportable between the sprockets so that the speed ratio therebetween can be altered. When encircling a sprocket, the traveling chain is locked or latched to the sprocket. The lock mechanism has a retainer pin and a locking pin. The locking pin is connected for conjoint movement with the retainer pin which is positioned in latched and unlatched positions. In the unlatched position of the retainer pin, the lock pin engages an opening in the link of the traveling chain thereby securing the traveling chain to the sprocket.
