, This invention relatestfo improvements in hull-structures'of ships and the like and has. 7
for one-of its objects to produce a hull'structure of greater strength thanthat Ofk II Q W II;
hull structures of similar weight -.1,
A further object of the inventioriis to.
produce a hull 'structurehaving a greater dead weight carryingcapacity than has been;
possible iwithr'known "constructions. 1 Y.
Another; obiect'of 'this invention is thet abolition of all verticallyfarranged frames I connected to the platingiofthe side walls illustratlng analternative way of arranging and the substitution therefor T of diagonally arranged frames thereby enabling greater """strength ona weight. for. weightbasis to be obtained thanfhas been possible heretofore.
Other objects of the invention are to reduce the cost of construction and also reduce the possible source of leakagethrough the skin "of the ship.
In the past it has been customary to construct hulls with vertical or longitudinal frames to which the side walls are attached and it has been proposed to brace the vertical frames in such constructions by diagonally arranged members said members in some instances being attached to the skin of the vessel.
The invention consists in the attachment to a plurality of substantially parallel ob liquely arranged frames which do not inter,

.1 t Figure 5 is a fragmentary perspective'view illustrating an alternative way of arranging fiat bulk heads and in which theimembers-g' forming thediagonal frames although interrupted areso connected with the bulkheadbulk heads without the cutting or interrupt? ing of the diagonal frames; and v Figure 7 is afragmentary perspective view 1 corrugated bulk heads and in which the inemfibers forming the diagonal framesa'lthough' interrupted arev so connected I with the bulk head that the strength.ofthejconstruction is maintained. I I w T In the form of constructionillustrated; in T the drawingseach side wall has threelongitudinal girders a which are of box or trunk 1 form extending substantiallyfrom'one end", of the vessel tothe other, see; Figure fZr-"Ih e longitudinal girders a to be associated with i i I a side wall'are connected together by frames 7 b which are diagonally arranged. 1 The' frames bmay be in the form of a bulb angle fi her cross-sectionsuitable-for attachment to the g rders a and for th atta h e thereto of the side plating g,
' jThe sidevplatingl 0 is connected to thedijagonal" frames 6 in anyordinary manner, for v example by riveting and the structure as a whole may be iprovided as illustrated" with a ;-keel (Z. and double bottom tanks 6;; v
Tojavoiddifliculties at the extreme ends of 'thehul'lstructure it'will benot'edthat the diagonal frames and theilongitudinalgir ders do not extend beyond av certain point; I

nary construction. 1
introduce the frequisitei transverse Y gel bulk heads gm provided, zsaidbulk heads 9 being of-ordinary fiatform; see Fig ures, and5, or of corrugated formsee'Figures fifand'l as desired. o R I p: The arrangements illustrated 'iniFigures 4 and 6 ,enable the continuity of the frames 1) a V to be maintained, the bulkheadjfg being suit as f whilst the arrangements illustrated in Figures 5 and 7 enable cost to be reduced, the frames 1) being cut to avoid the bulk head 9 to which said frames b are attached by brackets such as h.
For clarity of illustration the means for connecting the parts together such as rivets or the like are omitted and it will be understood that the introduction of such means is within the knowledge of those skilled in hull design and construction. I
When the bulk heads 9 are formed with vertically arranged corrugations then a short section with horizontally arranged corrugations is mounted on the side plating as illustrated in Figures 6 and 7 said short section having a vertically arranged web plate 70 (Figure 1) on the edge remote to the hull and r to which the bulk head with vertically arranged corrugations is connected in well known manner.
It will be seen that owing to the arrangement of the frames 1') in a diagonal direction not only is resistance afforded to local deformation of the hull plating in the event of impact with horizontal or vertical obstructions. but the material in said members is arranged in a more economical manner thus en abling a hull to be produced of a given size and strength which is lighter in weight than that obtained by known constructions.
The longitudinal girders a when formed hollow, as illustrated in the drawings, enable more adequate ventilation of the compartments of the hold to be obtained than has been possible hitherto certain of the girders a being adapted to be employed for the delivery of air to the compartments whilst other of the girders are adapted to collect air discharged from the compartments and deliver it externally.
It will be understood that the longitudinal girders a and diagonal frames Z) may be of any shape or cross section as may be found most satisfactory or convenient in use, the girders a when of box form being either oblong, square, triangular or polygonal or with one or more rounded sides in transverse section as may be most convenient.
As illustrated in Figure 3 the longitudinal girder a at the turn of the bilge is substantially triangular in crosssection whilst the.
remainder of the girders a are polygonal in form.
Although for the purposes of illustration all the diagonal member I) have been shown as inclined'in the same direction obviously if desirable or necessary the said diagonal members between any pair of bulk heads may be inclined in opposite direction to the members between another pair of bulkheads.

A main hull structure for ships and the like comprising only in combination a plurality of substantially parallel obliquely urn-directionally arranged frames between the bulkheads, a plurality of longitudinal girders connected to said frames, one of said girders being arranged at the upper part of the hull and one of the said girders being arranged at the lower part of the hull and plating attached tothe frames and girders so as to form the side walls of the hull.
8.
