ABSTRACT:
The sprocket drive chain of this invention is particularly adapted for right angle drive but may also be used for straight or various other angular drive situations. The construction lends itself to ease of manufacture and especially for the automated manufacture of chain. In the preferred embodiment the chain comprises interlocked links rotatably coupled, such as by a pin and bushing combination, with stamped side plates to provide an intermediate tooth (sprocket) opening. The successive openings are adapted to receive a tooth at opposite 90.degree. angles thus readily being adapted to a right angle drive. Other embodiments employ a common pivot to support the side plates in successive 90.degree. opposite directions, and a single plate version useable with a slotted tooth sprocket.
