Eight locations are thus afforded for the pivotof the idler1 arm. The stud to which the spring is anchoredmay in like manner be screwed into either one of two holesin a block similar to the one just described, and this blockmay be mounted in any one of the three remaining positionson the rear shield. The position which should be used willdepend upon the way the idler pulley rests on the belt. Whenthese parts are put in position, further adjustment may beobtained by screwing the hook in and out of the spring be-fore hooking them on to the attachment. Adjus
