He invented a plan for destroying the wreck, which was the same as one carried out by Colonel Pasley in 1839.
He also invented the 'sun proof' for testing the soundness of guns, long in use in the Royal Arsenal.
[2] He invented a petard, of which there is a model in the Woolwich laboratory; a crane for descending mines; and a harpoon for taking whales.
[3] For the last two of which he received premiums from the Society of Arts; and an apparatus for rescuing shipwrecked mariners, said to be identical with that afterwards devised by Captain Manby.
[4] In 1815 the House of Commons voted £500 to his daughter (Mrs. Whitfield) in recognition of the same invention.
