Abstract: 1,142,529. Rope &c. strainers. ANSELL, JONES & CO. Ltd. 30 Nov., 1967 [10 Dec., 1966], No. 55403/66; Heading F2G. [Also in Division E2] Means for securing a container to a supporting structure comprises a fitment 21 for securement to the structure and a device which includes a first part 10 arranged to have a rope, cable or chain attached thereto and a second part 16 arranged to be attached to the fitment and tensioning means 14 connecting said first and second parts, the second part including a shank 15 terminating in an eccentric head 17 arranged to pass through an opening in the fitment and to have a stud and socket joint with the fitment. In the construction the tensioning means is a tube both end portions of which are internally threaded, one end portion engaging the shank 15 of the second half which is externally threaded and the other end portion engaging a shank 13 of the first part which is also externally threaded with a different hand to that of the shank 15 so that rotation of the tube 14 in one direction draws the two shanks together and rotation in the other direction urges them apart. Rotation is aided by providing the tube 14 with the hole for receiving a tommy bar; alternatively, it can be provided with a hand wheel. Alternatively, the tensioning means can consist of two internally threaded sleeves fitted in the end portions of a tube, the sleeves engaging the shanks 13, 15; in a further tensioning means the shank 13 has threaded engagements with the tube 14, but the shank 15 is provided at its free end portion with a collar arranged to abut the inner end of a sleeve screwed into the end portion of the tube 40. The eccentric head 17 comprises a cylindrical portion 18 which is offset from the longitudinal axis of the shank and a pair of part-spherical portions 19 and 20, the portion 19 being integral with the end portion of the shank 15. The fitment 21 is a steel casting and has a generally flat base 25 which is formed with apertures 26 for bolting it to the supporting structure and a wall portion 27 which includes a pair of end portions 27a, the interior surfaces of which are of partspherical shape and four side portions 27b, the interior surfaces of which are of part cylindrical form; the portions 27b are arranged in pairs, the members of each pair being on opposite sides of the end portion of a slot 23, the central part of the slot separating the pairs; the end portions of the slot are wide enough to receive the shank 15 but not the head, whereas the central part is wide enough to enable the head to be inserted through it to engage the second part with the fitment. The relative sizes of the head 17 and the fitment are such that a second head 17 of a further second part can be inserted through the central part of the slot so that the fitment can contain two heads, each of which is towards a respective end of the slot 23. In a  modification of the fitment it is formed with reinforcing elements extending between the base 25 and the portion 27 and in a further modification the fitment is designed so that part of the head 17 is received in a recess 30 formed in the supporting structure. The first part shown is formed with a pair of jaws 11 through apertures in which a bolt 12 is passed to receive the end portion of a chain, rope or cable but in a modification the pair of jaws pivotally support a hook, the hook having a nose arranged to be held in engagement with the shank by means of a knock-off link.
