Abstract

6384. Jones, H. W., and Reid, H. S. March 13. Davits have at their lower end a swivelling pulley b, to enable the hoisting rope or chain l to be wound evenly on the barrel of the winch &c. The davit a is mounted by bearings k on a bracket f on the deck below the boat deck. A sleeve d is provided with a pin c which carries the pulley b, the pin having bearings i engaging a ring j fixed to the bracket f. Specification 6224/13 is referred to.
