Abstract
1382653 Towing guide H E STUBBS 24 March 1972 [19 April 1971] 13888/72 Heading A1A A towing guide for controlling the path of a trawl net or other submerged object comprises a hollow tubular rotor 12 supported by webs 14 and 16 on a non-rotating axle 26 extending through the rotor, the rotor 12 being driven through spur gear 92 and ring gear 94 by a three phase induction motor 70 fixed to the axle 26 by adjustable mountings 72. Fixed to the ends of the axle 26 are baffles 50, which are spaced from the rotor 21 by gaps 66 (Fig. 2) which are sufficiently small to impede ingress of water. Power for the towing guides is provided by a variable frequency electric generator on the towing boat, via a cable (102) which may also carry circuits for a net sounding device (100) (Fig. 5, not shown). The rotor 12, end baffles 50, and webs 14 and 16 are preferably made of an organic polymer-based material such as fibreglass, the webs being integrally formed with their bearings 18 and 20 which are preferably water lubricated rubber bearings. Warpage and lack of dimensional control of the materials are allowed for in the narrow water-impeding gaps 66, and in the provision of the adjustable mountings 72 for the motor 70 on the axle 26. The towing guide is connected to a net 42 as shown in Figure 1.
