Abstract

655,179. Stuffing-box substitutes. BARKER, G. P. May 20, 1948, No. 13743. [Class 122(v)] [Also in Group XXXIV] In a pin bearing arrangement for dredger bucket mechanism, the bearing surface between the bucket pin 10 and a sleeve 11 secured in the bucket eye may be lubricated by forcing grease through axial and radial. bores 24, 25, and packing glands 14 are provided at the ends of the bearing sleeve 11, each comprising a ring of rubber material 15 having a circumferential metal ring 16 and annular recessed metal rings 18. Each gland is disposed in a chamber 19 in a boss 20 and retained therein by a plate 21 bolted to the boss 20. The rubber material 15 may be that known under the Registered Trade Mark " Linatex." Non- return ball valves 26 are disposed at the outer ends of axial bores 24. Grease may be supplied through one valve 26 whilst the other valve 26 is held open to allow the old grease to discharge. In a modification only the outermost side plate 18 is provided and the adjacent retaining plate 21 is spot welded to the eye of the bucket. Specification 437,928, [Group V], is referred to.
