American engineer (1866–1945) who developed the first submarine to operate successfully on the open seas. Original signed pencil sketch of a cross-sectioned salvage tube on a beige 8.25 x 10 lightly lined sheet, with Lake adding copious notes and signing at the conclusion, “Simon Lake, Jan. 15, 1940.” In part: “Method of making up joint to salvage tube—the tubes are made up with male & female joint—section about 30 ft or more in length—the male end is entered the female section & the water pumped out between the bulkhead.” In fine condition, with a tear in the upper blank area.
