    Default The first propeller?

    JOHN PATCH

    John Patch, inventor of the propeller.jpg


    A sailor and fisherman who invented one of the first versions of the screw propeller.

    Patch was born in Yarmouth, Nova Scotia in 1781. His father Nehemiah was a Yarmouth sea captain who died in a shipwreck at Seal Island, Nova Scotia soon after John Patch's birth.

    Earning a living as a mariner and fishermen, Patch observed the efficiency of small boats propelled by single oar sculling and began to experiment with a propeller based in the motions of a sculling oar. During the winter of 1832-1833 he built a hand-cranked version of a doubled-bladed fan-shaped propeller. He demonstrated his propeller during the summer of 1833 before crowds watching as his small boat moved, seemingly magically, across Yarmouth Harbour. Patch further experimented by attaching his invention to a 25-ton coastal schooner named Royal George in the Bay of Fundy. The propeller allowed Royal George to enter Saint John Harbour in a calm which stranded other sailing vessels. Patch's invention was 4 years before John Ericsson's famous patent on the screw propeller in Britain. Patch lacked the funds to travel to Britain for a patent but instead tried to patent his propeller in the United States in 1832. However his application was refused as he was not an American citizen. Patch continued to improve his propeller and when American laws changed to permit patents by non-citizens, he received an American patent in 1849. Patch's propeller received some recognition, including praise for its efficiency in Scientific American magazine. However, by 1849 there were multiple competing versions of the screw propeller in Europe and America. Patch never received money or recognition.

    A petition by Yarmouth citizens to reward his innovation with a pension from the Nova Scotia government in the 1858 was unsuccessful and he died a poor man at Yarmouth in 1861.
    Hope for the best, but plan for the worst.

    One might say that this man of vision invented the propeller and got the shaft.

    There are two kinds of boaters: those who have run aground, and those who lie about it.

    Robert Fultons nautilus had a propeller

    A56FC872-6DD3-4FA7-A5B4-A2424A72A01E.jpg

    Robert Fultonís Nautilus was a time-out-of-place marvel of ingenuity. Built in a shipyard in Rouen, France, the Nautilus was constructed primarily from copper, with its metal sheets bent elegantly around a frame of iron. In a rather modern touch, it had a streamlined teardrop shape to reduce drag in the water. The Nautilus was roughly six meters long and two meters wide. The Nautilusís propulsion was provided by a geared hand-crank, that drove a screw. Nearly neutrally buoyant, via a series of weights and a simple pump, the craft could take on just the required amount of water to sink. With some depth attained, controllable horizontal fins (ie, diving planes) allowed the craft to rise and fall. Using a small spherical observation dome with portholes, the steersman could direct course.

    It was improved upon in 1806

    the end to the submarine didn’t turn out to be the end of Robert Fulton, who went on to design the steamship “Clermont,” which would found the world’s first practical steamship service. Unfortunately, his later success would never make up for all the money he’d spent on his vision of submarines. In 1815, in the middle of one of his many legal arguments about his patents, he caught a cold and died, having never seen the ideas he’d spent twenty years promoting, make their way into the world.

    While taking a Maritime History course in college 45 years ago, I did a paper on John Ericsson and his propeller designs. My research never mentioned Patch. Of course, this was long before computers so I just had my college library for research.
    I was born on a wooden boat that I built myself.

    To be fair, Michael's OP did say
    one of the first versions

    It really is quite difficult to build an ugly wooden boat.

    That sucky old page did not mention Fulton. Obvious from his drawings and builds - they were in use. Patch was 30 years after. Half model based on his 1799/1800 sub.

    And then there were the bamboo copters that children in China played with back in the 4th Century.

    Da Vinci's wouldn't have worked. Equal and opposite reaction, and all that.......

    An early marine screw design had two twists like that. It broke in half during trials, and the test vessel went faster.

    Wasn't Brunel's rather rough looking prop for the Great Britain actually quite efficient? even compared with more modern ones?

    Apparently it was.The design has been tested and found to be good.
