Abstract

537,969. Bucket-chain dredgers; hinges. PARKER, T. Jan. 13, 1940, Neo. 807. [Class 68 (i) ] In a dredger bucket-chain in which one bucket has a pair of spaced eyes between which fits an eye on the adjacent bucket, a hinge pin extending through all the eyes, during hinging movements there is relative rotation between the pin and the spaced eyes, and none between the pin and the other eye. Further, means are provided to prevent entry of water and grit, and loss of lubricant, in the bearings in the spaced eyes. In Figs. 1 and 2, the pin 4 fits preferably within a bush 3 in the eye 1, and is held against rotation therein by friction, which may be increased by serrations, or by a serrated block pressed against the pin, or by bolts, wedges, keys or the like ; the reduced ends of the pin fit Within bushings 5 held in the outer eyes 2 by similar means or by radial tongues 8 and bolts 9 threaded to the eyes or to blocks welded thereto. The bushings 5 may have detachable half or whole liners or ball or roller bearings. The closed ends of the bushings 5 have tapped holes 10 to facilitate removal, and nipples 11 and non-return valves for insertion of lubricant. At the inner ends of the bushings 5 are solid or hollow rubber &c. sealing rings 12 which may bear frictionally against metal &c. rings 13 which may have grooves for passage of lubricant, and may be of angle section to extend within the rings 12. The bushings 5 may be recessed to enclose the rings 12. In Fig. 9, the pin 4 is recessed to receive the ring 12, oil ducts 16 being provided.
