Ship's pump.
A suction-pump for freeing a ship's hold from water. That illustrated is provided with a chamber H above the deck, with which the head of the pumpbar-rel and foot of the suction-tube A communicate. The cover E and valve F are removable, so that ready access may be had to the interior of the pump. Down ton's pump is used in the British navy as a bilge, deck-washing, and fire-engine pump. It has three buckets, one above another, in the barrel, and an air-chamber in the head, so as to discharge a continuous stream of water. When fitted with deck or suction plates, it is capable of drawing water from three to six different parts of a vessel. |
