Abstract

338,451. Richards, F. Feb. 7, 1930. Shoring. - The ends of curved rails used as supports for mine shafts and the like are flattened at the meeting portions A, and the joint is made by straight-sided fishplates B, instead of the usual curved edge plates. The jointing plates may embrace the flanges and have wedge edges to increase the grip on the flanges.
