' deck, or decks, without, however, obtaining Be it knownthat I, CARL J onmn FRED MALCOLM LILLIEHGGK, a subject of the King of Sweden, and resident of Stockholm, Sweden, have invented new and useful Im' provements in Ships or Vessels, of which the following is a specification, reference being had to the drawings accompanying and forming a part hereof.

ships or vessels with-transverse frames and a small number oflongitudinal girders or beams in the bottom, andsometinies also in the sides, a comparatively greater strength is obtained athwartship than in the longitudinal direction. As, however, it is well known, that. the greatest strains arexthe bending-strains in a vertical plane in the longitudinal direct-ion of the vessel. it-will easily be seen that the longitudinal beams in the sides only imperfectly contribute to increase the vesse s power of resistance against such strains, hence, with the usual method, especially in larger vessels, it is necessary to make use of a strongly built the desired solidity and strength.

The. object of the present invention is to provide alighter, cheaper, and stronger construction of the various parts in ships or vessels, by making better use of the building material.

The invention consists in the combinations, arrangements and construction of parts hereinafter described and claimed.

In the accompanying drawings I ;have shown two ships or vesselsembodyingmy invention. Figures 1 and 2 are crosssections thereof. The left halves of the figures are sections showing the transverse frames or beams c, and the right halves are sections between them showing the longitudinal framing. Fig. 3 is a detail. A

In the sections the bottom and sides are built of continuous longitudinal frames and in Fig. 2 is shown a double bottom. The transverse strength is obtained bybulkheads, diagonals, and strong transverse-frames' or beams 0, consisting, preferably, of single or double U-irons, angles, 'or other suitable shapes, placed on the inner side of the former and at a suitable distance from each This invention relates to improvements in snIr onvEssnL.

other in accordance with the strength required.

When the room between the decks does .not admit continuous transverse beams under the longitudinal beams, the former may be made intercostal. When an iron deck 1s not used, plates are secured to the transverse-beams, and in these plates the deckplanks are secured. The deck is laid in the usual manner with stringers along the sid- .5 and the transverse-beams are secured to them and to the underlying beams orto the sides of the vessel by means of knee-plates. welded knees or otherwise asmost convenient. The stringer-plates are-su'pportedby knee-plates fastened to the side Where necdeck is not used, tie-plates are fitted to run' athwart the ship, between the transverse beams, from stringer to stringer plate; they may also be placed diagonally, and the deck may be laid in sections, if desired.

As it is principally the beams in the bottom and in the upper decks, which are situated far from the neutral axis, that contribute to the strength of the vessel in the longitudinal direction, the beams of the middle-deck .or lower deck may be placed athwart the ship in the usual, manner, see Figs. 1 and 2, and the framesc'ould, therefore, also be of the usual transverse type.

. By means of this construction the shellplating or the hull will be stronger for breaking or shearing stresses, as a less number of rivet-holes arerequired to fasten the plates at the longitudinal frames or beams.

and the holes are not made in a transverse c u o I.

seotlon as in the frames in the old system.

Having; now described my invention and construction, what I cla m as newand desire to secure by Letters Patent is:

1.' A' metal ship constructed with a plurality of continuous l0ngitud1nal beams directly attached to the deck plating,- and a pluralit of cross-beams disposed under the inner edges of the longitudinal deck beams; substantially as described. I

2. ,A metal ship constructed with a. plurality of continuous longitudinal beams directly attached to the deck plating, and a plurality of cross beams disposed under the inner edges of the longitudinal deck beams; the upper longitudinal beams of the vessel being in preponderant number in relation to the cross beams, substantially as described.

3. A metal ship constructed of longitudinal metal beams at the deck, sides, and bottom, to one edge of which the plating is connected, and transverse beams, the longitudinal beams being in a preponderant number in relation to the cross beams, and the latter bemg placed at great distances from each other, said longitudinal beams being connected to said cross beams and t0 the skin v 0m JOHAN FREDRIK' MALCOLM muaraeox.
