Abstract
A tufting machine having individual crank assemblies for reciprocating the push rods which carry the needle bar. Successive crank shafts aligned with each other and parallel to two main drive shafts which are rotated in opposite directions. Gears on the main drive shafts respectively transfer power from the two drive shafts so as to rotate each successive crank shaft in a direction opposite from the direction of rotation of the preceding crank shaft. The connecting rods connected to the crank assemblies thus are thrown outwardly in opposite directions as the crank shafts are rotated, so as to balance the machine. Additional counter-balance weights are provided on the main drive shafts.
