On this day in 1902 Axel Welin was granted the patent for APPARATUS FOR RAISING OR LOWERING SHIP’S BOATS. U.S. Patent No. 711,749.
This invention relates to davits which are so constructed that the davits themselves can turn downward, as in the constructions when the lower end of the davit is pivoted to the deck or when the lower end is in the form of a toothed quadrant which rolls on a rack.
Heretofore when the davit is lowered the boat is lowered at the same time, and thus a greater amount of power is required to hoist the boat inboard than is required to lower it out.
The object of this invention is to some extent equalize the amount of power that is required to launch a boat and that required to hoist it inboard.
According to this invention the tackle is so arranged that as the davit is lowered the boat is raised relatively to the upper end of the davit, and vice versa.
