Abstract
Knock-on sweep structure includes a wedge adapter having opposite sides with upper and lower surfaces that engage the wrap-around portion of the sweep stem. The upper and lower surfaces diverge at different rates from a narrow end to a wide end to improve sweep-adapter contact. In one embodiment, the upper and lower surfaces on each side are planar and define a compound angle. The differential rate of divergence assures early contact between the adapter and stem at a plurality of spaced locations for improved retention and more reliable sweep positioning.
