Abstract

788,854. Anchor-bolts. HILL PORTER (NEWCASTLE), Ltd, and TALBOTT, A. C June 23, 1955 [June 18, 1954], No. 17885/54. Class 89(1) An anchor-bolt, e.g. for mine-roofs, comprises a screwed-rod 2, Fig. 1, with a head 2a and a number of eliptical washers 3 spaced apart by sleeves 4. The lowermost washer is supported obliquely by a tube 5 during insertion of the bolt into a bore 1, the tube being turned and the rod pulled to cause an initial biting of the washers into the bore-wall, whereafter the tube is removed and a nut 9 tightened. The tightening may be continued until all the washers lie at right-angles to the rod-axis. In a modification, the head 2a is replaced by a nut and the nut 9 by a cap-nut. In another modification, the washers 10, Fig. 7, are initially bent, and subsequently flattened, by tightening the nut, to bite into the bore-wall. In a further modification, part-spherical washers are used.
