Abstract: 1,146,218. Stuffing-boxes. A. L. HENDRICKSON. 10 Oct., 1967 [25 Nov., 1966], No. 46220/67. Heading F2B. A method of inserting fresh packing in a stern gland 26 whilst the ship is afloat comprises (a) slackening the packing gland 30 until a gap exists between it and the stern gland, (b) inserting a barrier 46 in the gap to retain the old packing 28, (c) further slackening the gland 30, (d) inserting fresh packing 62 around the propeller shaft 24 between the gland 30 and the barrier 46, (e) tightening the gland 30 until the packing 62 abuts the barrier, (f) removing the barrier and (g) further tightening the gland 30 to force the packing 62 into the stern gland. The gland studs 40 have adjusting nuts 44 and locking nuts 42 abutting the stern gland flange 38. In repacking the stern gland the nuts 42 are first slackened to allow insertion between adjacent studs of metal sectors 46 and the nuts 44 are slackened until the gland 30 is just clear of the flange 38. The nuts 42 are then further slackened and a U-shaped spacer 56 is fitted over each stud, the sectors 46 then being driven radially inwards, to provide a temporary barrier for the packing 28, Figs. 4 and 10. The nuts 44 are further slackened and new packing 62, Fig. 5, is placed around the shaft and compressed against the shaft by a band 64, formed in two halves. The nuts 44 are tightened until the packing 62 abuts the sectors 46 which are then moved radially outwards to allow the packing, by further tightening of the nuts 44, to enter the gland 26. Finally the sectors 46 and spacers 56 are removed and the nuts 42 returned to their original position.
