- c : wane, 1914 Motor Life for Atlantic Liner An interesting novelty has been intro- duced by the Allan Line of steamships on board its two new liners Alsatian and Calgarian, in the form of motor. lifeboats. These were built by McLaren Bros., of Dumbarton, Scotland, and are fitted with Marconi wireless telegraph apparatus. The launches, one of which nay rip § i i MOTOR LIFEBOAT. FOR * ATLANTIC LINER has been supplied to each ship, are car- tied on davits at the aft end of the vessel, and are always kept in readiness for immediate use. The lifeboats have been primarily de- signed with the intention of making them absolutely unsinkable in heavy weather. With this object in view, they have been decked entirely fore and aft, with a small watertight cockpit aft of midships to accommodate the steersman and afford access to the cabin, which 1s arranged to seat twenty-eight persons. The hullis constructed of mahogany and oak of extra heavy scantlings. A special feature of the cockpit is the ample self- draining arrangement, which allows about 20 cubic feet of water to. pass out of the cockpit into the sea in three seconds, so that the cockpit should prove no source of danger in a heavy sea. At the aft end under a small hatch is fitted a winch on which about 500 yards of wire rope are coiled for use when towing other lifeboats, for rescue work, etc. The winch can be operated by hand from the cockpit, or it may be coupled up to and driven by the engine under the control of the engine clutch. Hand and power bilge pumps are fitted for draining the various compartments of the boat, should this at any time be found necessary. Substantial chain lifting slings have been fitted fore and aft. Within an air- tight compartment at the fore end is the main fuel tank, with a capacity to THE MARINE REVIEW allow of running twenty hours without replenishing. In addition to this, in each bilge are fitted fuel tanks which in turn replenish the main fuel tank by means of a pump connection. Thus, the boats have a total capacity for run- ning at full speed for forty hotrs. A watertight bulkhead is fitted between the cabin and the after part of the boat. The power plant consists in one boat of a Gardner paraffin engine of 20 horsepower, driving a MacLaren patent- ed reversible propeller through the latter firm's special form of marine clutch. In the other boat a Gleniffer paraffin motor is installed driving a similar pro- peller gear. A small dynamo driven by the engine supplies current for the wire- less telegraph apparatus. An arrange- ment is also provided for driving the dynamo by hand should the engine power not be available. Two specially long masts are provided, on which two 20-ft. aerials may be hung at a height of 25 ft. from the sea level, giving a range of communication of about thirty miles radius. Messages can also be transmitted over a two-mile range by 'the submarine signalling apparatus fitted on board. Under pressure from the engine a small compressed air tank supplies blast to the whistle. The boats are thus very complete, and are regarded as opening a new area in 235 The Late Alfred Noble American engineers will be gratified to read the tribute paid to the late Alfred Noble by Engineering, of Lon- don. Few men have been identified with so many great engineering under- takings as Mr. Noble, and his work was watched with interest throughout the whole engineering world: We regret to have to record the death, which occurred on Sunday, the 19th ult., at St. Luke's Hospital, New York, of Mr. Alfred Noble, the well- known American civil engineer. Mr. Noble was born on Aug. 7, 1844, at Livania, Wayne County, Michigan, where his parents resided on a farm. His grandfather served in the war of 1812, and his ancestors took part in the revolutionary war. He received his early education in the district school of his native place, and worked on his father's farm during his spare time. In 1862, when only eighteen years of age, Mr. Noble enlisted in the 26th Michigan Volunteer Infantry Regiment, and took part in the Civil War. From that date, until the year 1865, he served in the army of the Potomac through the whole of the Civil War, fortunately without being wounded; he was mus- tered out of the service in June, 1865, with the rank of sergeant. Immediately on leaving the army, Mr. Scale Vite 8 ae 4 Si 4 -- Dimensions: 28/0: 8/0"« 3:9" of Feet 5 wth) OO O20 Crile Con ae fO -- SHIP'S MOTOR LIFEBOAT the development of equipment for the saving of life at sea. There is little doubt, it is held, that many ocean-going liners will soon be provided with power lifeboats of this type. Three thousand "Boddy" life-saving jackets have been supplied to the Cunard Steamship Co. for use in the great liner Aquitania. Noble prepared to enter the University of Michigan; in 1867 he became a sophomore, graduating in 1870 with the degree of civil engineer. : . hiae He commenced his life as an en- gineer in 1868, and from that year to 1870 he acted as an assistant engineer on river and harbor works on the Great Lakes. From 1870 to 1872 he had charge of improvements on the St.
