Dougherty's patent "has for its object to so construct a rowlock that it will permit of the 'feathering' of the oar, while the latter cannot be detached from the gunwale or outrigger without lifting the thole-pin out of its socket; and it consists in a collar and a sleeve, each made in two parts, the former secured to the loom of the oar, and the latter pivoted to a forked swivel thole-pin inserted in a socket in the gunwale or outrigger..."
