ABSTRACT:
An energizing spring for a roller clutch of the type having a cage with horizontal and vertical cross bar pairs is provided with an improved latch. The spring is the accordion type, and the next to last fold thereof is a mounting fold sized to fit over a vertical cross bar. The last spring fold, which includes the spring tail, is open wider than the spacing between the vertical and horizontal cross bars. The spring tail includes a retrorse stop flange and a contralateral biasing finger spaced apart by slightly less than the raidal thickness of the horizontal cross bar, and the biasing finger is formed with a peak. As the mounting fold is pressed into place over the vertical cross bar, the biasing finger flexes past the edge of the horizontal cross bar, and once the peak of the biasing finger has passed the edge of the horizontal cross bar, the spring tends to self-seat. When the biasing finger has flexed back beneath the horizontal cross bar, and the retrorse stop flange has been flattened against the top of the horizontal cross bar, the pushing force on the spring may be released, and the horizontal cross bar will be resiliently captured. The latch so provided has a large zone of stability extending from the peak of the biasing finger to the stop flange.
