The _ driving engines are connected to. the conveyors so that either can be run independently or 'simultaneously, the power arranged being delivering at the rate of 500 tons per hour. Accordingly, it is estimated that in regular working the steam- ship Pallion will be unloaded in six hours, or, allowing for stoppages in moving barges, etc., seven to eight hours, and 'this, too, with but one stoker, one engineer, two laborers in the hold, and two adjusting the 'shoots or booms in the craft. The gear, be- ing placed quite independent of the cargo, is free to run empty, and all may be made ready and waiting for 'a start before the vessel is moored and the ibarges in position. This alone will save considerable time as compared with the work of rigging derricks, platforms, and the hand- ling of baskets, etc. The total cost of discharging the cargo of the Pallion will not exceed $60, including the upkeep of the gear; and it is affirmed that the cost of dis- charging a similar cargo at, for in- stance, the port of Hamberg, is about $560, and that in the work no fewer than 110 men are employed for about sufficient to. deal with a full load on both belts,. per hour. There is a complete system of signal bells fitted throughout the tunnel at the various discharge doors, which enables the officer on deck to control the supply on either or both sides of the vessel. The vessel jis classed with the British Corporation Registry, Glasgow. The advantages claimed by the in- ventors for this type of vessel would January, 1910 4 this will form an important factor as against the consideration of the probable increase of the harbor ac- commodation and facilities. Barge owners, again, will recognize the saving of time, and also the fact that the coal is delivered quietly from a reasonable height into the barge instead of being dropped in large grab loads, as is frequently done. Coal merchants and consumers will reap an advantage, as there is no great fall, and, consequently, a maximum of breakage or loss of weight. It should be here noted that the conveyors, while passing through the poop, are carried over two automatic weighers, each of which give the actual weight of cargo delivered. 'The cen- tral tunnel in the hold, being under somewhat 'similar conditions to a mine, is electrically illuminated and fitted with a ventilating fan and up- cast ventilator at the fore end, which is of such size as to form an access shait to and from the deck, . 'The tunnel also has free communication with the machinery space by means of a watertight door. A liberal esti- mate of the cost of discharge would not reach the sum of 2 cents per ton, ang at this cost the cargo is also weighed. We also have information that the Pallion has discharged recent cargoes in eleven hours, which is considerably short of the estimated rate previously noted. The estimated rate of un- loading with iron ore is 1,000 tons per hour. A comparison with the steamers ----} (Sollee ie Sig ae iz: SECTION SHOWING DELIVERY TO appear to be various.
