ABSTRACT:
A circular saw blade in which tooth assemblies are pivotally mounted along the periphery of the disc spaced apart at equal angular distances. Each tooth assembly has a U-shaped tooth wedging member pivotally mounted on the disc. The tooth is secured between the disc and the wedging member. Pivotal movement of the tooth wedging member in one direction wedges the tooth between the disc and the tooth wedging member. Pivotal movement of the tooth wedging member in an opposite direction releases the tooth from the wedging action between the disc and the wedging member. A cam locking member is rotatably mounted on the disc adjacent the wedging member. Rotation of the cam locking member in one direction locks the tooth wedging member in the tooth wedging mode. Rotation of the cam locking member in an opposite direction unlocks the tooth wedging member to enable the tooth to be released from the wedging action between the disc and the tooth wedging member.
