HULL STRUCTURE OF' SHIPS AND THE LIKE Filed ug. 21, 1929 2 sheets-sheet 2 Haro/d du/arid Esce/9m Cam/as I Patented Jan. 31, 1933 'rss HAROLD EDWARD rosonLYN cA'ivirs', or LoNDoN, ENGLAND HULL STRUCTURE OF SHIPSV AND THE LIKE Application filed August 21, 1929, Serial No. 387,323, and in Great Britain August 28, 1928.

An application has been filed in Great Britain, August 2S, 1928. This invention relates to improvements in hull structures of ships and the like and has for one of its objects the provision of a closed Y in accommodation alley way throughout substantially the length of the vessel.

A further object of the invention is to accommodate in the construction the various steam, water, electrical and mechanical services in such a way that more convenient inspection and utilization can be eected than is possible with known arrangements.

Another object of the invention is the provision of means whereby the cargo holds may be more effectively ventilated than has been possible with known structures, and whereby access can be had to the double bottom of the vessel at all times in each hold whether laden or unladen thus enabling drainage water to be removed with greater certainty than has been possible heretofore.

in additional object of the invention is the provision of means whereby increased longitudinal strength may be obtained compared with that of known structures on a weight of material per ton dead weight basis.

The invention consists in the arrangement of a closed in accommodation alley Way on and above the upper deck of a ships hull structure, said alley way extending for the greater part of the length of said structure so as to enable access to be had from one end of the ship to the other, said alley way in some cases communicating with the bottom of the vessel under each hold by means of vertical trunk ways.

1n the drawings Figure l diagrammatically illustrates the application of a closed in accommodation alley way in accordance with this invention to a Hush deck vessel having a forecastle at the forward end and a steering engine house at the after end;

Figure 2 is a plan of the vessel illustrated in Figure l; and

Figure 3 is a cross sectional view of Figure l.

As illustrated in Figures 1 and 2 the alley way structure comprises a forward section a,

an engine and boiler room casing ,25` and an after section c the threeparts being connected in any well known manner in order, that the stresses in the several parts a b and c are transmitted from one part to the others in an 55 adequate manner. y l The alley way structure a b 0 is arranged onland above the upper deck of the hull structure (see Figure 3) and accommodates steam pipes, water pipesyelectric Wires, steer- 60 ing lrods and other gear in such manner as toenable ready inspection thereof and rapid repairs thereto to be effected. The after end of the part c of the lalley Way terminates in the steering engine house diwhilsttheffor- 65 ward end. ofthe parta of said-'alley way terminates in the forecastle e, the closed in accommodation alley Way ab c enabling accessjto be had from one end of the vessel lto .the other and to the sounding pipes ofthe various holds, said alley way also receiving lthe air pipes from the double bottom. f ,E Iii-some instances the alley way or parts thereof may' be included `in the system lof ventilationvof the cargo holds inasmuch as the said alley wayY or parts thereof may act as a. duct orV ducts for the transmission of air to or from the various compartments.

In the case of a vessel constructedwith a poop, 'bridge andfo'recastle the alley way comprises two sections one located between the bridge and they forecastle and the other between the bridge and the poop, the two sections 4being associated withthe bridge structure-in such a manner that continuity of strength of the structure is maintained.

The longitudinal alley Way a b c may be connected with the double bottom by one or more vertical trunk waysg j@ i j c through whichaccess can be had to the" bottom of the vessel under each hold at alltimes even when saidholds are filled with cargo. The fbot.- Y Y tom of each of the trunk ways g h z' j mnay terminate' in a well Zin which drainage water from the holds will collect and from which it can be pumped in the ordinary way. i

As illustratedA in Figure 8, the drainage `arrangement comprises a Vscupper ppem draining into the ,Well Zand a suctionpipe frQle ,engineroom for pumping the drainage Water' out of said Well Z. As illustrated 'in Figure 3 the Well Z extends the full Width of the vessel but in some cases the said Well is only arranged in the centre portion of the vessel under a Vertical trunk Way in which case the piping must be rearranged. l

. Each vertical trunk Way rmay be provided With a manhole 0 at the upper partarrang'ed to enable access to be had to said vertical trunk Way from the'longitudinal alley Way and manholes pp at the lower part of said trunk Way in order that access can be had to the Well Z. To enable accessV to be had to other parts of the double bottomV the trans- Verse floors r may be provided With manholes g. VObviously if manholes suchas ok are ob-` jectionable in the longitudinal alley Way' thenisuc'h manholes may be replaced by small hatches.' l

I claim f yl. Afships hull structure comprising a f 'closed in accommodation alley Way arranged 'on and above the upper deck of the structure, Y

said alley Way extending for the greater part of the length or" said structure so as to enable access to be had from one end of the ship to the other including Vertical trunk Ways arranged to enable communication between the alley Way and the bottom of the vessel under each hold to be veected Without disturbance of the-cargo `in the holds, substantially as described. v v

2. A ships hull structure vcomprising 'a closed in accommodation alley Way arranged on and 'above'theupper deck of the structure, said alley Way extending forfthe greater` part 'of the length of said structure so as to enable access to be had 'from one end of the `ship to the other, said longitudinally disposed .alley Way being arranged in sections and connected f 1 to the bridge, the engine and boiler room cas'- ing or the like so as to 'stiien the hull structure as la Whole and 'enable communication to be established throughout substantially the length of the vessel, substantially as described.

3. A ships hull structure comprising 'a closed in accommodation alley Way arranged on and above the upper deck of the structure,

said alley way extending for the greater part y ofthe length of said structure soV as to enable V access to be vhad from oneend of the ship to the other, said longitudinally disposed alley Way being arranged in sections and connected to the bridge, the engine and boiler room casingfor the like so as to stiffen the hull structure as a Whole and enable communication lto be established throughoutv substantially the length of the lVessel andfverti'calftrunk Ways connected to said alley Waysections to Venable communication between the alley Way andthe bottom ofthe vessel to be effected Without disturbance ofthe cargo* inthe holds,
