toggle iron การใช้

Lewis Temple was an African-American blacksmith who invented the toggle iron, a type of toggling harpoon, which revolutionized the whaling industry and enabled the capture of more whales.
The toggling iron harpoon was even more successful and rapidly phased out the use of the " common harpoon " ( a term which refers to either the one or two flue harpoon ).
In 1848 Lewis Temple, an African-American blacksmith in New Bedford, Massachusetts adapted the toggling harpoon using a wooden shear pin to initially brace the toggle head, and created what came to be known as " Temple's Toggle " and later simply as the " toggle iron " or " iron toggle " harpoon.
