A third plan is to raise the wreck by directhoisting power. An instance of this is Bishopsfloating-derrick, shown at Fig. 1617, page 688. 4. Vafeas plan for raising sunken ships consists in first clos-ing hermetically the hatches, port-holes, and all other openingsin the deck or upper or side parts of the sunken ship, and thenpumping air to the bottom of the ship through tubes in-scrtei eitner throjg 1 the bottom of the ships hull, or throughthe deck, eich tube being passed down close to the bottom ofthe ship. The air thus introduced rises by itself toward theunder side of the deck, and, not being able to escape, water contained in the ship down and out through the hole Fig Haisin-Seeder. made by accident or through holes made for the purpose Thevessel will thus be rendered buoyant, and will rise to the surface Raisin-seeder. (Household.) A machine fortaking the seeds from raisins. The examijle showsthe usual form. The falling from the hojipere down the spout / are iinjialed upon closely setwires on the cylinder by revolution against a rubberdrum ; a scraper removes the seeds from the sur-face, and the pulp is subsequently drawn cff liewires and collected. The wires are set so closely asto force outward the seeds ; these, when removeil bythe scraper, fall into one drawer, while the pulji re-moved from the wires by the rake m falls into theleft-hand drawer.
