4644. Gemmell, D., and Stewart, W. Feb. 23. Hatchways.-The tarpaulins covering a ship's hatchway are secured by a batten consisting of two bars 1. 3, one of which is adapted to slide over the other and is fitted with wedge surfaces 4 which engage cleats 5 on the coaming. The two bars 1, 3 are kept together by studs 7, which may be fitted with clamping-nuts 10. By sliding the bar 3, the wedges force the bar 1 towards the coaming, securing the tarpaulin.
