28 AN INTERESTING REPAIR JOB AT SEA. We have been favored by D. W. Bavaird, the secretary of the Glas- gow Branch of the Marine Engineers' Association, through our British rep- resentative, with the two interesting THE MarINE REVIEW tugs sent out to assist made their appearance. The 'whole"repair was managed in 48 hours' time. Three holes, 154 in. diameter, were drilled through the adjoining collars, and re- cesses were cut in one of the collars for receiving the heads of the bolts, BROKEN photographs showing how a_ broken shaft at sea was repaired. This in- teresting repair job took place about the middle of January last on board the screw steamer Hestia, of the Donaldson line, which broke her thrust shaft while on a voyage from Glasgow to Newport News. The ves- sel is of 3,790 tons gross, and - 2,434 tons net, and was some two days out when the breakage took place. <A severe gale was raging ai the time, and during the five days thereafter, she drifted some 256 miles. The Hestia's thrust shaft was -21 ft. long, 1314 in. diameter in the body, with collars 22% in. diameter, and 33% in. thick. The shaft was completely broken. When the chief engineer, Angus A. Urquhart,: had determined to effect a repair, even in the adverse circumstances, he availed himself of the' assistance of the mates of the ship £0 try and stop the tail shaft and propeller from revolving with the vicious lashing of the sea. When all seemed secure enough by meaus of the wire rope lashings they aJopted to effect this, these were torn asun- der as if they had been spun yarn. The chief engineer then got the ship's carpenter to fill up the. spare eccen- _ tric strap with wood and cut a circle to fit a coupling which he fitted as a brake. This device proved effective, and the repair was proceeded with and completed, and the ship was ready to resume on her own before SHAFT OF THE STEAMER HESTIA, OF THE DONALDSON LINE, \ so as to clear the thrust web. After fitting the three 15£-in. bolts through the collars, thnee keys were aiso fitted on the edges of the collars as shown in the illustration. Two of these were 14 in. long by 5. in. by 13% in., and repairs were completed the Hestia then steamed to Greenock en route for Glasgow, a distance of 367 miles,' which she accomplished in 47 hours 20 minutes. Although she was ac- companied by two tugs, which had been sent out to her assistance, the vessel was self-propelled all the way. Proceeding up the Clyde, the engines were operated to send the _ vessel ahead and astern even more than usual, and this, together with the movements in docking,: certainly af- forded striking testimony to the. eff- ciency of the repairs. to the shaft. The underwriters have made some recognition of the skillful way in which this repair was accomplished under most trying conditions to the vessel brought safely into port under her own steam. From one of the photographs of the shaft taken after removal from the ship, it will be observed that the internal stuffing is anything but what may be termed a homogeneous mass; the wonder is that the shaft ran so long--about 15 years.
