902) MARINE REVIEW. : 29 COALING AT SEA-BRITISH ADMIRALTY TESTS. The Lidgerwood-Miller marine cableway, manufactured by the well- known Lidgerwood company of 96 Liberty street, New York, and de- signed to transfer coal, ammunition, supplies and provisions at sea, was described in the Review some time ago when tests were made at sea COALING THE TRAFALGAR AT SBA. between vessels of the United States navy. Important improvements have lately been made in the system and attention is again directed to it on account of sea trials undertaken by the British admiralty. It is re- ported from England that results of the admiralty trials point to the practical solution of this'most troublesome of problems confronting naval COMPAGNIE GENERALE TRANSATLANTIQUE FRENCH LINE--UNITED STATES AND EUROPEAN MAIL ROUTE.

SMOOTH-ON | IRON CEMENT IS A POWDERED-METALLIC-COMPOSITION which, upon being mixed with water, becomes a hard metallic IRON, that is insoluble in water, steam or oil, withstands fire and expansion and contraction--being the same as Iron 1s why it is sometimes called MAGIC IRON. ee When applied to a blemish in a casting the blemish is removed. Hundreds of breaks or fractures in hydraulic machia- ery, leaks in connections in steam or water work, have been permanently and cheaply repaired with SMOOTH-ON. Send for 60 page illustrated book.

Other tests are to follow on battleships in this country and it is confidently expected that the cableway will be generally adopted for the United States navy. Russia has already applied it to the greatest of her battleships, now building in this country at the works of the Cramps, Philadelphia. The London Times, most conservative of the English publications and the one standing closest to the British govern- ment, said after the British tests that the "problem of coaling war ships at sea seems near to solution." Mr. Spencer Miller, the inventor, is confident since these latest trials that whatever difficulties may have been en-' countered heretofore in the perfect working of the device have clearly been overcome in a most satisfactory manner in the latest form of. the cableway and that its capacity has been increased to a degree that will enable it to give the maximum service desired. It will be remembered that in the trials made by the United States navy department it was required that the cableway transfer 20 tons of coal an hour with a distance of 300 ft. between ships speeding at the rate of 6 knots. This was accomplished in a heavy seaway. In the test by the British admiralty the required amount to be transferred was increased to 40 tons an hour and the distance between ships 400 ft. (making for greater safety), while the speed of vessels was almost doubled. These tests, made off Portsmouth in the English channel on the 4th inst. with the battleship Trafalgar and collier Muriel in tow, lasted three hours and are reported to have de- veloped a maximum of 40 tons of coal trans- ferred per hour. The engraving on this page shows the two British vessels while making the tests and gives a good idea of the working of the cable- way. The pair of sheaves which were form- erly required upon the after deck of the tow- ing vessel and a canvas chute down which the bags of coal were dropped have now been done away with. When the load of bags reaches a point in transit immediately over the after deck of the receiving vessel all the cables are pulled down to the deck, the loaded bags deposited, the empty ones hooked on, and the. cables tautened up again and' traveler re- turned. In the test by the British admiralty a large square mast was fitted in the fore part of the collier Muriel and from the top of this the cableway extended to the quarter deck of the Trafalgar. An-elevator runs on rails secured to this mast and hoists a ton of coal in bags 65 ft. up to the mast head. A traveling carriage takes the coal bags from the elevator and transfers them at great speed to the war- ship. <A trip every minute is easily accomplished. The traveler is pro- pelled back and forth by a wire rope %4-in. in diameter, operated by two direct-acting engines having two 10x10-in. cylinders and slipping drums. Instead of using a sea anchor to keep an equal strain on the main cable between the vessels, the same result was ingeniously accomplished by the use of a main cable tension engine, which automatically keeps the cable taut while permitting its length to vary. This engine has two 13x13-in. steam cylinders, and is geared to a slipping drum. The engine turns in the same direction all the time and the slipping drum is given a definite power of about 5 tons by the slip of its friction heads. Hence the drum maintains a constant pull on the main cable, revolving one way and then the other as the movement of the ship requires greater or less length of cable.
