Abstract

165,042. Hasselberg, B. A. L., and Ostberg, K.. G. June 18, 1920, [Convention date]. Wire couplings.-Relates to apparatus for raising sunken ships of the type in which floats carrying guide-lines are released from the ship, and comprises a form of automatic coupling by means of which lifting.cables are connected to the ship. The float carries a length of thin wire coiled within it, which as the float rises, runs out against a resistance so that the wire is kept stretched. The lower end of the wire is secured to the coup: ling member 3, Fig. 3, which is attached by a chain to the framing of the ship. The lower coupling member consists of two concentric sleeves with internal flanges. The upper coupling member 7, secured to a guide line, is threaded on the float wire, and lowered till it engages within the sleeve 13. Freely movable balls 28 are housed in pockets 29 in the member 7 arranged askew with respect to its axis and so shaped that the balls may project but cannot fall out. Helical springs may be arranged behind the balls. The member 7 thus freely enters the sleeve 13, but on passing the flange 19 the balls fall outwardly and lock between spherical recesses in the pockets and the hollowed underside of the flange 19. The coupling member 12, to which is attached by means of the eyes 22 a lifting chain, is then threaded on the guide line and lowered to engage with the sleeve 3, the upper part of the member 7 being coned to assist the engagement. Locking is effected by means of the balls 25, the action being the same as that of the smaller coupling. If necessary, two or more guide-wires may be employed before the final lifting chain is lowered, further couplings being arranged concentric with the first. The Specification as open to inspection under Sect. 91 (3) (a) also describes a modified form of coupling of general application, shown in Fig. 5 (Cancelled), in which spring-pressed balls 37, housed in pockets in the sleeve 35 engage in recesses in the head 33. Between these recesses the head is cylindrical, so that disengagement may be effected by relative rotation of the members. In a further form of this modification, the balls are housed in pockets in the head, and engage in recesses in the sleeve. It is also stated that the locking balls in the form shown in Fig. 3 may be replaced by rollers or clutch teeth. This subject-matter does not appear in the Specification as accepted.
