Abstract
A blade tensioning mechanism for a band saw is provided with a block slidably mounted on the saw frame and carrying a movable, non-driven, i.e., idler, band saw blade wheel. A link extends through a cam follower secured to the block and carries a pivotally mounted cam for engaging the cam follower. The end of the link opposite the cam is threaded and is engaged in a threaded bore of a rotatable shaft which is carried on the frame and which is restrained against displacement relative to the frame. A handle is connected to the shaft through a preset torque limiting device whereby the blade can be pretensioned to a predetermined amount by turning the handle to move the link, cam follower, block, and idler wheel relative to the frame. The cam can be subsequently pivoted against the cam follower to further move the idler wheel a predetermined amount to apply a final, operational tension.
