IMPRovED SAILING-VESSEL `Fon SToRING AND TRANSPORTING PETROLEUM AND OTHER oILs. 4

The Schedule referred to in thes'e Lettera Patent and making part of the same.

I, PASCAL AQUINAN, of the city of Baltimore, in the State of Maryland, have invented certain lmprovements in a Sailing-Vessel for Stowin g and Trailsporting Petroleum and other Oils, of which the'following is aspecfication.

The objects of my invention are to construct a vessel of iron, to be propelled by the ordinary method, with masts, rigging, and sails, for carrying oil in bulk,

thus avoiding the necessity' for barrels, separate tanks,

or Aother vessels for holding the oil, and, at the same time, securing the cargo from the danger of combustion, leakage, and other damage incident to the ordinary means of transportation; also, vto enable a vessel to carry a much larger amount of oil than` could possibiy otherwise be the case by the usual mode, and also to economize in the expense of loading and discharging cargo, cooperage, carting, housing, and storing, which is accomplished by my plan of' pouring the oil, by meansof hose, or other simple device, directly into the ship.l

Figure 1 isa longitudinal sectional view. Figure 2 is a plan view of the deck.

Figure 3 is a transverse section from a-b.

Figure 4 is a view of the oil-register.

Figure 5 is the iloat for the same.

Figure 6 is the screw-cap for deck.

Figure 7 is a man-hole plate.

,Figure 8 is the escape-yalve.

Figure 9, section of wooden tank, having escape- Figure 10, section of iron mast, with escape-valve.

A is the hull, constructed of' iron plate riveted to iron ribs, without inside skill, but divided into a convenientnumber of oil-reservoirs T, see figs. l and 2 B are the bilgc-pumps, which pass through the deck I C, ihr the purpose-ot' keeping the run or hilgc free of water. These pumps have no well, and pass to within a short distance of the floor of' the vessel.

'lhe interior of the vessel is divided longitudinally, fore and aft, throughout'its entire length, by a partition or bulkhead, l), constructed, preferably, of boilerplate fastened to angle-iron. By this means'the oil is prevented from surging, or shifting from side to side,

when the vessel or ship lies over on its side or careens, andthe vessel is also greatly strengthened and stiffened by said bulkhead.

A sufficient number of transverse bulkheads, E E E, are also inserted, to divide the interior into separate compartments, for carrying diliercnt kinds ot' oil and better stowage. All of the said compartments are intended to be perfectly tight, so that one should not be affected by a leak in another.v

Fis a fresh-water tank or compartment, just above the kelson an'lidships, with a roof or tight cover of'4 iron, and contains thewater for the vessels use, and communicates with the' deck above by a. pipe, a, intended for a pump.

Above said water-tank, in the space marked 1S, provisions arc stored, with a hatchway, b, for access to the same.

The deck of this iron vessel isl perfectly tight, having no communication with the oil save by circular holes c, each about three inches in diameter, and leading into'the oil-compartments below, and each filled with a screw-cap, fig. 6, which will be removed, when necessary to pump oil in or out.

To allow for the escape of' gas, each oil-compartment is fitted with an escape-pipe, or, preferably, each mast,

if' of wood, is furnished with such escape-'pipe d, or each mast, if' of iron, may be tubular, and serve as such escape-pipe.

, 'lo prevent waste and deterioration, each escapepipe or iron -mast has a valve, e, fitted in, from twenty to thirty feet, lor other convenient distance above the deck.

Each compartment is fitted with a floating register, j; see figs. 4 and 5, passing through a suitable pipe, g, fig. 4, and having a graduated scale showing the exact height of the oil -iu each reservoir. v

For the purposes, of' repairs and cleaning the different reservoirs, there areufitted man-hole plates h, perfectly water and oil-tigh It is well known that the coal-oil of commerce, of' 11()o Fahrenheit standard fire-test, cannot ignite except' by the actual presence of' flame, when heated tothat degree hence there cannot be danger of combustion, save from such contact, and such contact cannot occur in this sailing oil-vessel, as no lcommunication is allowed with said oil, nor can the inflammable oil or gas come into contat with' the dame, as isv sometimes the case in ordinary wooden and other vessels, by the permeatiou of the escaping gas, or bythe incantious use of candles, lamps, or otherlighted matter, in the hold cabin, or otherplaces into which the gas has flowed.

Should the vesselA not bleiullof' oil, if desired, water can be' admitted, upon which 'the oil, from its less specific gravity, will float, and the oil can be pumped out at pleasure.

Should the vessel leak, no harm can ensue to the oil, an admixture ofr it with water being impossible, and the water can be pumped out, as indicated. The register showing the actual Height of the oil in the ship, and its capacity, and that of each compartment being accurately known, the ,real amount of oil can, by simplecalculation, 'easily be ascertained.

The advantages of my improvements are as follows:

First. lhe cost of constructing my safety iroutransport, or sailing oil-vessel, is lessthan for constructing one on the ordinary plan, owing to the absence of interior decks and ceilings, while my oil-vessel can easily be adapted to the ordinary purposes of transportation;

Second. The entire cost of the barrels is saved by my plan. As each barrel costs from two to three dollars, in a small vessel of fifteen hundred barrels (or sixty thousand gallons) stowage, at least four thousand dollars would be saved in this single item alone, besides allowing about thirty per cent. more carrying capacity, thus obviating objections that may Wellbe urged against anyplan of separate tanksntbe hold of a ship, which latter plan necessitates great additional expense, Vbesides loss of room; and

Third. The danger of accidental fire is rendered nearly, if not quite impossible, thus lessening rates of insurance, great loss, dto.

I claim, as my invention- 1. The combination ofthe hull A, deck O, fore and aft vertical bulkhead D, transverse bulkheads E E E,

b, fresh-Water pump a, all constructed and arranged, and for the purpose described.

,2. The combination of the oil-reservoirs 'l with the bilge-pnmps B, floating register j, register-pipe g, the circular holes c, with the screw-caps c, with the hull vA and deck O, all constructed and arranged, and for the purpose described.

3. The escape-pipe d and valve e, as fitted to mast, with valve e asscrewed into tubular iron mast, all constructed and arranged, and for the'purpose described.

4. The safety iron transport, or sailing oil-vessel, with the partsABGDEFSTabcdefgh, all combined, arranged, and cmzstUcte'd substantially as and for the purpose described.
