Abstract

807,549. Spring boards. HUNT & SON Ltd., H. May 11, 1856 [May 13, 1955], No. 13828/55. Class 132(1) [Also in Group X] A springboard comprises a series of longitudinally extending aluminium alloy elements of tubular or box-like cross-section secured together side by side so that their upper walls form collectively the deck of the springboard. As shown, extruded aluminium alloy elements 10 are secured together by bolts 11 with washers 12 and nuts 13 and the ends are closed by end plates 17. The alloy may be fully heat treated and contain 1 per cent silicon and ¥ per cent magnesium. Matting is secured to the fixed end 14 of the board and extends over the other end 15, a rung on its end engaging over hooks 16 formed on washers 12 held by nuts 13. Sections 10 may be of triangular section and may be cemented together instead of bolted. The alloy may be anodized or otherwise treated to make it resistant to corrosion. The elements may be spaced apart by washers or the like and the board may be tapered.
