1851 Great Exhibition: Official Catalogue: Class VIII.: Edward Auqustus Inglefield
99. INGLEFIELD, EDWARD AUGUSTUS, R.N., 9 Portsea Place, Connaught Square — Inventor.
Model of H.M. brig " Flying-Fish," fitted with a screw- propeller, to be worked by the capstan; also gearing for connecting the screw-shaft with the chain-pumps. A new application of the capstan, and of the chain-pumps.
A small lever handle throws the screw into gear with the chain-pumps, and the revolution of the screw, consequent on the motion of the ship through the water in a gale, or even at anchor (in a tide-way), will pump the vessel out, without any manual labour.
An anchor without a stock, and both flukes taking the ground, when in use. It is stated that this anchor cannot be fouled, nor can a ship damage herself should she ride over it. It has double the hold of an ordinary anchor; it takes into two pieces; is easily tatted and fished, and is simple in manufacture.
