Abstract
A vaulting board is fastened at one end to a frame and slopes up under the action of two spaced apart, concave upwards, leaf springs carrying rollers on each end which contact the under side of the board. The spring centers are clamped in assemblies carrying transverse shafts at the bottom and the curved ends of J-bolts fit around the shafts and are connected to the frame, so that the springs pivot about the shafts axes under vaulting impact to equalize the stresses impressed in the board by the spring ends.
