When the after end of the cargo thas run to its natural angle of repose, the operator now in the hold View SHOWING OPENING OVER CONVEYORS. are catried forward and hinged at the poop front, and the delivery end is suspended by suitable tackle from twin masts or framework, and 1s raised or lowered according to cir- cumstances, delivering the load into telescopic shoots suspended therefrom. When the delivery is into trucks, the "offside" belt delivers amidships into a cross conveyor suspended on the masts, which carries the load to the shore side and delivers' by shoots into the trucks. A development of this principle has, however, been ap- plied to the Pallion, as, in order to obviate the use of delivery shoots, which result in considerable damage, the terminal conveyors are carried in swivel booms, which are raised or lowered and swung overboard to the points of delivery, thus permitting of the cargo being conveyed direct to the truck or barge without shoots. These booms may also be swung across to the reverse side of the ves- sel so that both booms can deliver simultaneously into trucks or ware- house. Another important feature of this discharging arrangement lies in the method of delivering the cargo to the belts from the hold, and enab- ling the operator to have full con- trol and free access at all times to the conveyors and to the face of the cargo. He may thus superintend and direct the continuous flow, and be in a position promptly to correct any tendency of the cargo to 'bridge or to choke the aperture leading to the belt, which being the smallest space the load has to pass through, insures a continued and uninterrupted de-- livery. : For unloading a coal cargo the point the space is naturally only par- tially filled. The slide door in the covers over the conveyors is drawn back by the operator in the tunnel, and the loose coal over it immediate- ly travels on to the conveyors, which may or may not have been started. If running, then the flow continues; if standing, no difficulty arises be- cause the conveyor is only loaded at that point, and the aperture becomes blocked and only clears and flows when. the belt is started. Then, if no. "bridging" occurs, the after part of the hold is readily emptied on to the conveyor which is carrying it on deck and or barges: If, however, any "bridg- ing" -is threatened, the operator in into the receiving trucks VERTICAL SLIDE Doors IN Hotps. merely removes the first cover and places it aft of the aperture, allow- ing another portion of the cargo to run, he being in a free position to maintain the run and correct any tendency to bridging and to abnor- mal: rushes. Jf. such do. occur. ana incline to block the aperture, he again corrects this, and, having run so much more he removes the next segment of cover, and so on, gradually trans- ferring the aperture from the after end to the fore end of the _ hold. The wing tanks and central tunnel being sloped, the cargo gravitates to the aperture and the finals are manip- ulated by the operator, one man be- ing on each side of the hold. 'An important feature is the inclined a Pa Ce ee ee ------ STERN ViEW OF PALLION, DiscHARGING Over BoTH SIDES. © the tunnel ascends to the chamber, and has free access over the aper- ture to correct any block.
