Abstract
Tensioning devices for maintaining tension in a chain of a chain saw are disclosed. An example tensioning device includes a housing adapted to be coupled to a drive cog of a chain saw, a saw bar mount adapted to be coupled to a saw bar of a chain saw, and at least one spring adapted to bias the saw bar mount in a distal direction from the housing, thereby tensioning the spring. The tensioning device may also include a ratchet and pawl assembly that allows the saw bar mount to be moved in the distal direction and stops movement of the saw bar mount in a proximal direction. The tensioning device may also include a lock adapted to hold the saw bar mount in a proximal position against a biasing force of the spring. Methods of assembling components for maintaining tension in a chain of a chain saw and of operating the assembled components are also disclosed.
