34 TAE MARINE Review MASTER AND ENGINEER. In the past years a strained feeling existed between the deck and the engine room departments on board steam vessels. The origin of this bad feeling is historic. With steam came a new class of men into ships, and a new department over which the captain was commander, yet before its intricacies perfectly helpless. Previous to the introduction of steam everything on board was sub- servient to the master's will. He was master in name and in truth. A new master crept on board with the steam,--the chief engineer. The motive power lay in his hands. Ancient prerogatives were invaded. Civil war fol- lowed the evolution wrought by steam. Many of the dif- ficulties between these two departments are now amicably settled, at least as far as the larger class of ships are con- cerned, although they linger still in cargo ships. The cap- tain, was not always as civil and courteous as he might be to the engineer. Once while bringing his ship along- side of the wharf in Buenos Ayres a gallant captain was indulging in sulphurous language incidentally aimed at the engineer, when that worthy looking up through the skylight cried loud enough for the passengers to hear, "Captain, the passengers will think you are talking to 2) . me In the eyes of some engineers of steamships the deck officers of their ships are profoundly ignorant. Here are some of the stories they tell: A young mate went into the engine room with a message from the captain to the engineer. The latter saw the other was interested, and began to explain things to him. Being a civil and obliging - man he made no attempt to tell fairy tales to the stranger, and, moreover, he kept as clear as possible of all puzzling technicalities. He pointed out the cylinders, the various rods, the eccentrics, the shaft, and so on, explained rough- ly the uses of the various pumps, and auxiliary machinery, and the mate was genuinely pleased and interested, and said so, Then, when going up on deck again, a thought seemed to strike him. Halting on the ladder, he called the en- gineer and explained the difficulty. "Thanks, awf«lly, for showing me around, Mac; you've made the whole thing as plain as a pike-staff. But one thing I don't quite grasp. What are the boilers for?" "A burly, thick-headed skipper had been given the com- mand of a little steam collier. Going up with great pride onto the bridge of his new ship, the first thing that caught his eye was the engine room telegraph. 'What's that for?' he demanded. "Why, that goes down tothe engine room,' was the reply. 'You see all the orders on it--"Full speed," "Half speed," "Slow," "Stop," 'You just have to move the handle.' The old man was charmed. 'If Aa put the handle to "Full," will she gang full speed?' 'Why, certainly.' 'An if Aa put the handle to "Stop," will she stop ganging?' 'Certainly.' The old man was still more charmed. Final- ly, after thinking some time, he heaved a great sigh of pleasure. 'Why, that's fine, man! That's clever! That does away with all them saucy devils o' engineers.' " Another old Scotchman was coming alongside at South Shields in his new command. With great stampings on the knob that rang the engine room bell, he had at last got abreast of where he wanted to be, but rather far out. He was puzzled as to the means of getting close in. He jumped on the bell knob and rang great, incoherent peals in the engine room. But it had no effect. Matters seemed to go slightly worse. Finally, in undignified despair, he turned. and addressed his engineer by word of mouth: 'Aa divent waant to gang aheid! Aa divent waant to gang astern! But just gie 'er a wallop on the port side' '-- . Sailors' Magazine, New York. DIAMOND IMPROVED TURRET ATTACHMENT. The Diamond improved turret attachment manufactured by the Power Specialty Co., 513 Washington Arcade, Detroit, Mich., is designed to be used on single spindle drill compres- sors, boring machines and lathes. Every manufacturer is aware of the fact that much valuable time is lost on the drill press by changing drills and handling work several times for the different sized holes. The Diamond turret attachment instantly converts the single spindle machine into a gang dtl, _ It is superior to the gang drill in that every tool in use is in perfect alignment with spindle of machine, thus a job clamped to the table, or a heavy piece being operated on, subject to a series of operations, need not be changed. For drilling and tapping this device has no equal. It is so con- structed that it responds at once to the reverse motion of the machine. It also converts an ordinary lathe instantly into a turret lathe by simply inserting its shank into tailstock spindle of the lathe. Many operations may thus be performed as readily as with a turret lathe, such as drilling, reaming, boring, tapping and turning. For special operations, the same forms of special tools as are used in turret lathes will be required. The attachment consists of two pieces, one of which is loosely mounted on spindle, which fits socket in machine spindle, either taper or straight, as the case may be, while the other is adapted to revolve on first mentioned piece, being suitably guided and carrying four-spindle sockets, each hav- ing Morse taper-hole to receive tools. By the operation of latch the two pieces are locked together at the same time clutch is engaged and tool is in motion. There is nothing complicated about this device. When ordering be sure to state size of shank and whether taper or straight, Morse or Brown & Sharpe. In the table of turbine steamers, built and building, published by the Marine Review of Dec. 28. Turbinia II built for the Turbine Steamship Co. at Hamilton, Ont., is credited to Swan & Hunter as builders. Of course, it is well known on the great lakes that the Turbinia was built by R. & W. Hawthorn, Leslie & Co., Hebburn-on- Tyne, but it is easy to explain how the Review fell into this error. The table was taken from Mr. E. M. Speak- man's paper on "Marine Steam Turbine Development and Design" as read before the Society of Naval Architects and Marine Engineers in New York and was published as printed in the proceedings of the society.
