Abstract
A drive assembly for reciprocating connecting links includes a single, main drive shaft and alternating, counterrotating and direct individual drive assemblies. The drive assembly is particularly adapted for use in devices such as carpet tufting machines which require high speed reciprocation of connecting links and push rods. The drive assembly is designed to counterbalance undesirable multidirectional reciprocating forces generated by the drive assembly itself and other machine elements. The drive assembly, therefore, operates at high speeds while reducing overall machine vibration.
