,Ta all whom it may concern.-

Be it known that I, GEORGE SHONE, of East St. Louis, Illinois, have made anew and useful Improvement in Ships, of which Vthe fol-' lowing is a full, clear, and exact description.

The improvement relates to those ships which are classified as non-sinkable'P; Its leading feature is a water-tight chamber arranged centrally and extending vertically and longitudinally in the hull of the ship and dividing the cargos'pace of the hull into two 4parts-namely, that contained within and that surrounding said chamber-and having floating-power to sustain the ship when said space surrounding said chamber is waterlogged, as described, substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this speci# Figure 1 is a plan of the ,improved ship; Fig. 2, a side elevation, partly broken away to show a portion of th'e interior in section; and Fig. 3, a vertical cross-section on the line 3 3 of Fig. 2. l '1 Only those parts of the ship are exhibited which are essentialI to an understanding of the improvement. Various features are indicated by the broken lines in the dierent views. 4

The same letters of reference denote the same parts. f

A represents the hull. VIts dimensions in most cases are substantially the same as those of an ordinary ship of equivalent capacity, and in shape the hull may be varied more or less, according to the size or style of ship being built and the specialplan of its builder.

'The water-tight chamberB in its general out. -line conforms somewhat to` th'e hull, and in length and width it is suciently smaller than the hull to cause a space C-say, from six feet to twelve feet in width-to be formedbetween the side a of the hull and the side bof the water-tight chamber. The bottomb'of the chamberB is also raised above the bottom a of the hull to form an intervening space C', which in practice may not be as deep asis the width of thespace C. The watertight chamber is arranged centrally in the' hull,'and it is carried up to project above the top of the hull,

substantially as shown,and it is made watertight from its bottoni upwardx to above the PATENT; :Grauen rs Patent Nq. 424,568, dated Aprn 1, 1890.'`

top of the null, and the projecting upper porpreferablymade water-tight, but so that from pose incidentto-the operation and use of the ship-that is, ,any machinery employed 1n moving the ship is contained within the water-tight chamber, as well as the passengers rooms.- The freight is designed to be carried not only within the water-tight chamber, but also in the space C between the shell of' the Bulk-heads Dare used partly to strengthen the ship and partly to divide it into compartments. They extend crosswise in the vship neath the water-tight chamber, and they also may extend" across the-levater-t'rglitchamher.

or some of the bulkheads may across the Water-tight chamber, and some' which are extended vacross the Water-,tight tight chamber into water-tight compartments b2. The compartments a?, into which the' space C C is divided by means 'of the bulkheads, are preferably not made Water-tight* that is, by means of some small opening, suchl as shown at d, Fig. 2, Water admitted into a compartment can llow thence not rapid1y,.,but gradually, into the othercompartments cl2, ahd the ship thereby kept trimfor if the hull is stove in,say, at the bows the water 'enters that part ot the 'space C, and if it is retained there the ship is' liable to be depressed at its forward en'd only; but if the water is allowedto ilow thence throughout the length of the hull the ship settles evenly -in the water'. v.

By means of suitable water-tight decks E the space G can be suitably divided horizontally fon receiving freight, whichcan be. introduced through the hatchways e. These hatchways,by meansof suitable hatches, can be adapted to be water-tight, so that` any wator admitted into the space ,C shall be conined to that deck or decks in which the leak occurs. The decks are braced with diagonal 1,) by which means the structure is considerably strengthened.

The present improvement 'is not restricted to what are termed ships strictly. It in Vpart can be embodiedin many kinds of waF Myl leading object is not to provide a cellular construction, but to forni a non-sinkable ship with as little additional weight of parts as possible, and 'so that the carryiug'capacity of the'ship shall not be reduced more 'than is due to the extra weight of those additional parts, to which endl form the described water-tight chamber, arranged centrally and eX- tending longitudinally in the ship and having its shell spaced' inward from the outer --shellof the ship, as descrihed, and providing 1.v A ship-hull having a central watertight chamber whose shell is separated from the shell of said hull by a surrounding Space through which water entering therein through an opening in the shell of the hull can flow around said central chamber, whereby said hull is kept trim, substantially as described.
