Abstract: A lateral travel limiter for the chain of a chain drive assembly as commonly seen on multi-speed bicycles. The chain lateral travel limiter attached to a bicycle frame proximate to a front derailleur and the front chain rings, and is positioned with respect to the front derailleur and the front chain rings so that during a shifting event, and in the event that the front derailleur shifts the chain laterally from a first plane defined by an outer chain ring to second plane defined by an inner chain ring and the chain travels laterally beyond the second plane defined by the inner chain ring, the chain is caught against the chain lateral travel limiter and guided in a manner that redirects the chain to the plane of rotation defined by the chain when engaged and rotating on the inner chain ring.

Abstract: A cutter blade (17) for a finger joint cutter head (10) which includes a cantilevered cutting tip attachment. A cantilever pocket (20) is formed in the fillet area of steel backing member (18) to receive and hold the inner end of a hard material cutting tip (19), such as tungsten carbide. Cantilever pocket (20) has tapered sides which diverge outwardly and a rounded vertex or pocket bottom. Cutter tips are elongated to extend well into cantilever pockets (20). Each cutter tip is attached within a pocket (20) and along the joint surface of steel backing members (18), using a sandwich braze, to form braze joints (21) and (22).
