application. that To all whom it may concern: v

Be it known that l. Enormnn llanria'r li ac.- nIN-Ano Liaraimnnrnni, a citizen of the liepublic of France residing in llieppe. tleii'ielnl rieure, llrance have inventeiil certain ne Y and useful l inprovcinents in tloinpoinid Barges, of which the following is a epecit'e cation.

The irn 'ention relates to a. marine barge formed by coupling together two or more barges which. are both internally nally cylindrical snch has been dencriltied in applicationv for United Finite-a Letters Patent No. 185,704, filed August ll, lllll'.

The invention is illustrated in the accompanying drawing, showing; the, c-on'iliiination of two barges situated side by side.

l igz ire l is a side elevation of the barge;

l ig. 2 is a transverse section thereol on a larger scale;

l igg 3 is a plan tl'iereiiit' partly in lltlllilfiil'" tal section;

Figs. 4.- and 5 are crossa-iectional diagrams; illuatrating the ellect elf tloodintt certain con 1 p art inentti Fig. 6 a detail View drawn. to an enla-rg'ed scale of a hatcliway partly in eection. as viewed from its end.

l ig. l" a plan of the eaid hatch ay.

llelt'erring to Figs. 1,2 and the two cylin drical halls are marked :l and ll rcnpectively. They are connected by sheet iron plates a, b, 0 which are perfectly tight.

it has been shown in the said application that barges consisting of a cylindrical hull such as A or ll. are substantially llllSllllItLblt. The compound. barge consisting of these element-e and shown in the accompanying drawin in also practic: lly unsinllable.

For this p urposse the two hulls are always strictly cylindrical interiorly, and a water ballast chamber subdivided.by tight trans verse part 101155 (I is constructed between them in the partlimited by the Pitl'titions 7) and 0. ln this; manner the hulle always we serve for any liquid cargoes a devclo ml interior inetaccntcr reduced to a point.

It follows that for all such carggpes the point of support at any inclinat-imi ot' the vessel is identical with the center oi' each cylindrical hull which is; the geometrical, position of all interior inetaccnters. lhe center of support of the whole cargo thus re mains constantly on. the intersecting line of llWUJltlllGS of symmetry oi the vessel h: N and f Y and its constancy being than ase'peclitcation of Letters latcnt.

The arrangement of the water-ballast between. the lnills A and B also has the ad vantage that aceessi can be attained to the plates of the water ballast chamber so that l tcrnai .ltecl 15 given by the relatlon when l the moment of inertia of the interiial flotations and l the volume of the ballast.

The water ballast also comprises" horizontal transverse batlle plates which are not t l-fl t and complete the connection of the bulls and break up the shoclna and blows of the heaving ballast.

Finally, the part comprised between the plz'ites a and 0 terms a tight passage affording room for movement from end to end under shelter. This passage contains particularly loading and navigating apparatus, such as winches, capstans, or the like. l t also tonne a. storage eon'ipartment. if necessary, for the equipment and. serv'ce of the vessel generally. Thus, the vessel has the same qualities as the barge described in the said application for llnited t'ltatcs' letters Patent. It is (JU'fl' stitutcd of elemcntn completely capable of being developed and it is practically incapable of being); submerged and capsizing. illorcovcr, it shows-great security against torpciloce and other damage since. any accident to orient the hulls; does not iniperil the existence of the vessel which always remains aulliciently afloat by reason of the reserve ol flotation provided by the space be tween the hulls. This is illustrated by Figs. 4 and 5 which how the heeling consequent on the blonine open of a portion of the compartments of one hull; in Fig. tit being .allow the two wheels 6 which are nearest to the screw 9' to be brought into position and mounted on the cover by inserting their pivots or axles in a hanger 70; the rails f can then be engaged in the grooves of the, wheels by unscrewing the screw g.

A similar operation at the other end of the cover places the latter on its four rollers and thus allows longitudinal dis1' laccment of the cover. Rey erse operation places the cover in the position in which it closes the hatchways.

To prevent the cover from running free on the rails during the operation, a brake Z holds it in place.

Having now fully described my said invention and the best means I know of carrying the same into practical effect, l claim 1. A compound barge comprising a number of individual barges consisting of bulls which are cylindrical both internally and externally, and a framework connecting adjacent barges, the said framework also being internally and externally of cylindrical contour and comprising a water ballast and a storage compartment.

2. A compound barge comprising two substantially cylindrical hllils and a frame-- work connecting them comprising an up er arched late a lower convex )late and an intermediate plate or deck, the space between the upper and intermediate plates constituting a longitudinal passage, and'the space between the intermediate and lower plates constituting'a water ballast. chamber.

3. A compound barge comprising a plurality of individual barges of approximately cylindrical form arranged side by side, and an intervening frame-work connecting them comprising top and bottom plates and inclosing a chamber constituting an intermediate hull.

4. A compound barge comprising a plurality of individual barges ofapproximately cylindrical form, each sub-divided by transverse bulk-heads into multiple compartments, said barges arranged side by side, and an intervening frame-work connecting them comprising top and bottom plates, and inclosing a chamber forming an intermediate hull.

A compound barge comprising a plu rality of individual barges of approximately cylindrical form, arranged side by side, and a framework connecting them consisting of top and bottom plates constituting an intermediate hull with its lower portion sub divided by transverse bulk-heads into successive ballast compartments.

6. A compound barge comprising a pinrality of individual barges of approximately cylindrical form, arranged side by side, and a framework connecting them consisting of topand bottom plates constituting an inter- -1ncdiatc hull, and an intermediate plate div1ding such hull into a lower chamber which'may contain ballast, and an upper chamber constituting a longitudinal deck, and transverse bulk-heads dividing such lower chamber into successive ballast compartments.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
