Patented May 5,1908.
Application filed April 9, 1995. Serial No. 310,801.
To all whom it'may concern:
' -Be it known that l, OTTO MEHR'rENs, a subject of-the Em eror of Germany, and a resident of Kiel, ermany, have invented cert'ai'n new and useful Im rovements in Transport .Vessels, of which t 1e following is he present invention relates to vessels for carryingcargo in bulk such as coal, grain and the like. In the construction of such vessels, .ship owners prescribe the following condi- I V ti'ons, among others: 1-. The vessel must be self-trimming, that is to say, the filling of the i cargo sp'aces mustf, as far as possible, take place automatically withoutany considerable stowing work; any gaps left'unfilled or de- *ve" loping from the settlingiand ,jolting to- *gether of the cargo must be such that they [can fill automatically from the material in the hatches and in the superstructure by the movementsofth vessel at sea, withoutinterfering With the stability of the vessel.
is to say, the rolling period of the vessel must not be too short. 3. The vessel must be cagable of-holding such an'amount of water allast that the propellerwill be completely submerged when the vessel islight.
I? It has been suggested to comply with the above-mefitioned requirements by constructing the side Walls of the holds with an angle of inclination to the horizontal plane, corresponding to the'angle of rake or slope of tanks, are reckoned in the measurement for dues, charges for towage, etc.
port or cargo vessels constructed as above-,
tonnage and are, thereiore, not exempt in the assessment of dock, harbor, canal, andother Hence transoutlined are disadvantageous as far as the taxable or assessable space is concerned.
The objectof the present invention is to provide a transport-Vessel, which'comes up to standard requirements, and which, moreover combines a maximum of bulk ca acity and tonnage with a minimum of tax assessable space.
. 2' V The stability of the vessel must be good, that aleor A transport vessel embodying the present invention is shown diagrammatically inthe accompanying drawing, in which:
Figure 1 is a cross-section of the vessel, taken in a plane near one of the hatches,.and Fig. 2 is a cross-section taken through or ad; jacent to the bridge. I
The vessel is provided with a double hull, A, B, which is continued notonly throughout the bottom as in ships heretofore constructed, but extends up to "the harbor-deck C on both sides. The space between the walls A and B is adapted to receive water ballast and is divided by means of lor-lgitu dinal partitions D into compartments 'rvhich may communicate with one another in any suitable manner; The harbor-deck insurmounted by a seaproof superstructure E, 6, extending throng out the length of the vessel and having its sidewalls e extending upwardly directly from the inner wall B of the hull and at an angle of inclination to the horizontal plane, ap roximately correspondin to the rake or s ope of the cargo. The si e wallsof the hold are free from projec- ,tions or irregularities so as to be perfectly smooth. On the superstructure are arranged hatches F (Fig. 1) and the customar projecting parts such as the smoke-stack 8i and the bridge H (Fig. 2). i
It will beeasily understood that a vessel constructed according to the present invention complies with the standard require- Water ballast is placed in the double-hull extending up to the harbor-deck the entire ballast space, contrary to known ship-constructions, is free of assessment, according to the international system of tonnage measurement forsea-goihg vessels.
Besides'the advantage of a-low measurement, othe'r advantages accrue from the presence fof the sea-proof superstructure. According to the practice followed by-classiffication companies (surveyors), I- a- "smaller free-board (the perpendicular distance be tween the draft-line and the edge'of the sheer-plank, amidships) is allowed in vessels having continuous sea-proof superstrue ture than in vessels Without such a structure. A greater draft of the vessel is, therefore, permitted, and a larger loading capacity of the vessel obtained. Furthermore, thepractice of these companies, as far as the strength of material (plating and the like) is concerned, permits of the vessel being lighter when it as a continuous sea-proof superstructure. A vessel equipped in accordance with the present invention has, with a very slight measurement and a large loading capacity,
a comparatively small intrinsic Weight (net displacement) and consequently a comparatively large carrying capacity.
. The firmness of the hull of the'vessel is increased and the danger of leakage decreased by having the double-hull continued clear up to the harbor-deck. Furthermore, by placing the Water ballast the continuous double hull A, B, a better protection of the hull, is obtained than is the case in vessels having separate Water. ballast tanks. In practice, suitable means Will be embodied ture surmounting the harbor deckand having I side Walls extending directly from the inner Wall of the hull and inclined to the horizontal at an angle approximately corresponding to the rake or slope of the cargo.

A transport vessel having a double hull extending throughout. the bottom and ,upto the harbor-deck, and a sea-proof superstructure extending throughout the len th of the vessel, surmounting the harboreck, and constructed With sidewalls inclined tothe horizontal, at an angle approximately corresponding to therake or slope of the cargo the sidewalls of the super-structure extending directly from the inner wall of the hull.
