BALFOUR, OF CORNER BROOK, NEWFOUNDLAND BARGE FOR PULP WOOD AND THE LIKE Application filed 3Iay 31,1928, Serial No. 281,854. Renevved February 27,1931. This inventio.-i relates to new ancl usef-Lil im rovements i7i dump @arges ail-d particiiP larlv to barzes for carrying ptilp -wood, saw logs, and the like. The object o e, cr @@@rthe inve -ntion is to provide vess ge of siraple ccnstru&Lion which will be very easily and q-Liiekly loaded ancl tuiloaded with little man-tiltl labour. A-no'L,her object is to provicle t b,,tr(ye whieb 10 will be -Linloaded by mechanically ol:)erated means. Accorcling to our invent@@on the hull of the vessel or barae is coiistrli&ued to carry all of its load on deck. The clecli: is of the .15 riclue t.ype slopino- -Lip-wardly and fron-i the sid@ oi @he vess@l towarcls the centre, to facilitate the un'Loacling of the caruo whieh is held in place on said OLeek by hinged doors, eael-i of which is btiilt of t series of stan2,10 chions suitably he'Ld to(yether. The cargo d@ck is dividecl into con-ipartments by ,t series of blilk heads extending across the vessel. Th-, iorwird and after decks extend above the I,vel of the cargo deck to protect the c,,trgo, to pro@ide extra bouyancy for 1 the vessel -@.o provide suitable qli@rters for the crew, r@nd also to provide engine spice. Means are a!-so provided for diseliarging t@he cargo when th6 logs cannot be floated off. IVIecha-.qical iiieans are provicled for loal-ling the vessel. In the dr,)wings which illtistrate our invention Figure I is a plan view of a barge built 05 accordi-na to otii@ i,-ivention. Figtir, 2 is a side elevation of the barge shown i--ti Figure 1.

Referrina more particularly to the clrawipgs, It designates the hull of t vessel havino- a fore deck 12, aiid an aft deck 13 and the intermediite or c,,tro;o cleck 14. The cergo cleck is mide in two sections, each slopin- ii,.wardly ap-cl Lipivardly from the sides 15 to-",ards the centre of the vessel. The caro-o decl-i: is divided by a lonaitticli- 60 n,tlly di sposed bulli:head 16 extep-diii(r be een the fore and ift deeli:s which are pi-efer,,tblv positioned at a higher level than the I cai-o-o cleck, to provide accommodation for the creiv ind for the eiigines or propellin(r r,,5 mechaiiism. The c,,trgo deck i-s also divided into sel)arate eban-ibers on each side of the central bulli@head 16 by me,,tiis of the bulklie,.tds 17, which extend from side to side of the vessel. In the drtwing we h,,Lve shown 7o the cargo deck divided iiito eio-ht separate ch,,tmbers, btit it will be readily understood that this number is for illtistrative p-Lirposes only and iiiay be modif-.ed to suit the size of loo-s and the size of btrge. Each ch,,in-iber is 75 -i a zn p@'ovided witl - do6r IS hincyedly attached to the side of the vessel c-Lt the deck level. The doors are prefer,,tbly iiiide of L series of sp@teed staiiehi-ons or sltts 19 tied to-ether cl 80 iiear their ends by mea--Lis of the bars 20 a-@i 21. Each of the slats m,,ty be provided with an. eye brack-t 23 pivotally inounlu-ed on b,,Lrs 22 exteiiclino, the f Lill length o-j' the cai@go deck and forming hinged connections for the doors which, ii the uprigl-it, or cargo 85 holdi ng position, are held against loiagituclinal bars 24 by means of la@uches. These latch es coinprise pawls 25 pii,otally seeured to the bars 24, w-ith the free or hooli:ed ends enga ging wi@uh round bars each ex'uending oo the full leiag4uh of tl-i@ doors to wliieh they are attached. Each door is pi,ovided with a plur ality of enoa(ying pay@ls 25 secured to a n zn com mon sha-'Lt 26, to oiie end of -,vhich a leve r 27 is secured, so that on movemert of or% w said lever, the pa ls inay be operated in unis on.

The loading device is showli clearly in Figures 4 and 5. 5 In Figures 1, 2 aiid 3, a series 6f derriclcs 31 are shown, each pair of derricks beiii(t connected together by a beani 32, Trom wliieli the hoisting ropes 33 depeiid for lifting thc@ cargo 34 iiito the cliaiiib,-,rs l'oriiied iii the 10 vessel. The ropes are raised aii(I lowered by means of winches in the usu,,,,l iiiai-ino-r. The derricks are shoivn pivotalli, iiioiiiited oii upright niembers 3,@. so that car,o iiiay be lifted from eacli side of the bir-e. The, -argo inay be lield iii I)I@ice by ii-teaiis of 15 (@ chains or ropes 36a wliieh I)ass arouiid pulleys 36 and are ti(yhteii,,,c] bv iii(-,aiis of the winches or capstais lol', slioiyn iii Figtire 6. The chains niay be ari-aiiaed in zi(;--za@r f aslin el 20 ion across the top of ttie cirgo or in th,-manner shown, so that thei.,e will be practically no movemeiit of the coiiteiil-s of ti-le vesse,l while same is in nio'ciolli. Some of the pulleys 36 are securecl to th,-, cei-itre bulk25 head while the remaii-icler are sectii-ed to tl,,e door stancliions 19. TI,@e v@iiiel-ies ii-iay be hand or poii@er operated. To facilitate uiiloading of the, car-yo, Linloa,,Ilii(,, cliailis i)S are provided, as shown iii Fl,,-,ures 8 aiicl 9. 30 These chaiiis are securecl to ttie sicle of the hull and fit iiito (yrooi-es 39 foriiied iii the cargodeck.

It will 40 be readily seen that rniiiy iiiodificatioiis iiiay be made in the creiie.@al coiistrii(,tioii oi! ttle device without@ d7epai-tiii(-, froiii t'he spirit ofthe invention. 27:1 In operation the caroo whicli iiiay be clit p 45 logs, is placed ill position oii the cargo deck by means of the derricks, or by n-ieaiis of clump trucks ti@avelinc, on the rail positioned at the centre of tliemvessel. The slings 42 .for the car-O may be of any desired type 5o well known in this ai-t. The gates tre ill the closed or upright positioii. The slope of the deck tends to arraii-e the loo-S with tn zn their longitudinal axes substa-iiti,,tlly parallel so that ttie vessel may be easily loaded 53 to its full capacity without iiecessitatin(y hand labour arrancring the locys oii the said . t5 n deck. The chains or ropes 36a are ti(,htened over the cargo to hold same in place, by operatiiig the capstans to which the so chains are attached. When the vessel is loaded, the cargo deck is partially siibmer(,,-ed, as showii by the water levels 42. It will be seen that the fore and ,Lft decks protect the cargo from the froiit aiici reai-, whicli the gates, bulklieads and chaiiis hold the cargo firmly in position. In unloading, the cliains 36a are slackened off tnd the gates opened by raisin'Y the latelies holdinfr t@ in same. The gates fall outwardlv as sl-iown by the dotted Iiiies 43, and, biing of the 70 open or slat type, siiik below the water level rapidly. The (@@irgo, &r the 1-ntjor part of it, rolls outwirdly aild flotts from the deck of the vessel. The vessel rises in the water as the load is beiii- i-emoved and in some 75 cases soi-ne of the load reiiiains on declc, and to facilitate the complete discliar-e of the car(,o, the chains 38 are drawn by means of t"he drun-is into the position sliown as 3Sa in Figure 9, that is, uiitil they f orm a 50 straight Iiiie betweeil the side of the vessel gnd the dr'ums to which they are attaclied, formin- tn aiigle of tpproxin-iately 500 witli the ho@'rizontal. The niovenieiii of the c-hains causes the reiuainincy part of the car- 85 (yo to be rolled clear of t"he deck, without 'necessitatiii(y haiidlin(r of the lo(,Ts. I-, tn The vessel is of very siinple constrtiction iii(I I-,i-oi,-id,,,s a -%,- essel oi- bir(ye whicli may be. quicklv loaded Ind unlot@ied with the go minimuiyi I ,iiiiount@ of 1-iandling of the locrs ivliieli are iis@@d iii tl-ie paper makino, industi-y, ,iiid the like. The raised fore and aft decks allow space for the crew ,tnd for the iiecessarv mechanism for propellin(y the ves- 95 sel aiid'opertting the mecha,nism " mounted oii the vessel, -,is well as formin- a protection for the cirgo and gii,in(r zn additional buoyancy to the vessel. The loaclin- and iinloadin(y mech--tiiism is i,cry Silliple - (ind by loo pi,oviding coinpartii-ieiits, the vessel inay be I)ai,tially unloac'led without interferiii- witli tile reniaiiicler of the cargo. By carryidg the car o oii deck it lias been fouiid that the cost of handlin@, same dtiting the loadin(y 105 t@ n operation is Lboiit 40 to 50@lo of the cost of loading steamers by piesent methods, as practically no labotii@ is reqtiired for stowii-ig the cargo into holds. Since at least 75@'o of the' caro bein(-, discharo@ed from 110 z:l tD t,lie bai-ge herein described rolls or is floated off wlien the gates are opene(I and the reiiiaiiiin(r 25c/o 1'.s tinloadec-'[ n-iechinic(illy, iio stevedores ire required for uiiloadin tliereby s,,tviiig practically ill the expense of iir, liandling iiecessai-y in vessels where the wood is carried in holds. Having thus described our inventioii, what we
