It happened that at this time (the summer of 1850) his Grace the late Duke of Northumberland, who had always taken a deep interest in the Lifeboat Institution, offered a prize of one hundred guineas for the best model and design of such a craft; so I determined to complete my plans and make a working model of my lifeboat. I came to the conclusion that the cylindrico-conical form, with the frames to be carried completely round and forming beams as well, and the two screws, one at each end, worked off the same power, by which one or other of them would always be immersed, were worth registering in the Patent Office. I therefore entered a caveat there; and continued working at my model in the evenings. I first made a wooden block model, on the scale of an inch to the foot. I had some difficulty in procuring sheets of copper thin enough, so that the model should draw only the correct amount of water; but at last I succeeded, through finding the man at Newcastle who had supplied my father with copper plates for his early road locomotive. The model was only 32 inches in length, and 8 inches in beam; and in order to fix all the internal fittings, of tanks, seats, crank handles, and pulleys, I had first to fit the shell plating, and then, by finally securing one strake of plates on, and then another, after all inside was complete, I at last finished for good the last outside plate. In executing the job, my early experience of all sorts of handiwork came serviceably to my aid. After many a whole night's work--for the evenings alone were not sufficient for the purpose--I at length completed my model; and triumphantly and confidently took it to sea in an open boat; and then cast it into the waves. The model either rode over them or passed through them; if it was sometimes rolled over, it righted itself at once, and resumed its proper attitude in the waters. After a considerable trial I found scarcely a trace of water inside. Such as had got there was merely through the joints in the sliding hatches; though the ventilators were free to work during the experiments. I completed the prescribed drawings and specifications, and sent them, together with the model, to Somerset House. Some 280 schemes of lifeboats were submitted for competition; but mine was not successful. I suspect that the extreme novelty of the arrangement deterred the adjudicators from awarding in its favour. Indeed, the scheme was so unprecedented, and so entirely out of the ordinary course of things, that there was no special mention made of it in the report afterwards published, and even the description there given was incorrect. The prize was awarded to Mr. James Beeching, of Great Yarmouth, whose plans were afterwards generally adopted by the Lifeboat Society. I have preserved my model just as it was; and some of its features have since been introduced with advantage into shipbuilding.[1]
