Abstract: A roller carrying yoke is mounted on the base of the belt sander for pivotal movement about a pivot screw as controlled by the adjusting mechanism which includes a carriage bolt non-rotatably mounted in a slot in the yoke. The slot allows movement of the yoke relative to the bolt. The bolt projects through a hole in the housing and threads into the knob. A spring compressed between the yoke and the housing frictionally loads the knob so it holds adjustment. The yoke moves the roller away from the fixed roller until the roller engages and is limited by a belt. Then the loading spring is stretched to tension the belt. The tension spring force is cancelled out as the lever is actuated to pull the roller back for belt removal. When the cam follower on the yoke engages the cam (operated by the lever) the spring length remains constant and the actuating force is minimal.
