TOWINGvNCHORAGE FOR TOVVED BODIES.

1,319,565. Original application iiled September 18,

- To all whom t may concern:

l Be it'known that I, CHARLES DENNis'roN BURNEY, a subject of the King of Great Britain, residing at Dean Holme, Kilmeston, Alres'ford, in the county of Hants, England, have invented certain. new and useful Improvements in Towing-Anchorage for Towed Bodies, of which the 'following is a specification.

rlhis invention relates to means for attachng a towing cable to the head' of a towed body intended to be towed from a ship, more especially a body provided with an explosive charge by which a submarine vessel or other body may be destroyed. The towing cable may be an electricall one and serve to convey current forI actuating the firing mechanism, but this frms no 'part of the present invention. rlhe towed body may be of the kind described in the specification of my application No. 192019, from which the present application lis divided,

and no known under the name of a parav vane.

The chief object of the present invention is to provide a secure anchorage for the towing' cable, which anchorage permits of relative. rotation of the towing cable and towed body or paravane without slacking.

1n order that the said invention may be clearly understood and readily carried into effect, the same will now be described more fully with reference to the accompanying drawings, in which Figure 1 is a section of the head of a towed' body or paravane showing in section the anchorage for the towing cable; and

Fig. 2 shows a modication.

The paravane forms no part of the presentinvention and only a small portion of it is shown yin-Fig. 1, including the head 1, with a depressing plane 2 which causes the paravane to be deected downwardly .and outwardly in known manner when it is towed through the water, and with striker mechanism 3. f

The towing cable 68, which is an armored electric cable, is connected to the anchorage 69 in the head of the paravane. This consists of a plug 70 internally threaded .and with 'an aperture in the lower face through which the inner core of the cable passes. A sleeve 71 is mounted on the armored part of the cable and/carries an inner sleeve 72 adapted to rotate within the outer sleeve 71.

i The armoring of the cable isanchoredin the following manner. Rubber buffers 73, a washer plate' 74, a splicing bush 75 and a sp-licing ring 76 are fitted over the armoring, the splicing ring lhaving a head or flange 77, formed with holes 78, through which the strands of the .armoring are passed. The strands are then bent back as at`79 against the outside of the ring. Thebush 75 and ring 76 are formed with divergent and convergent adjacent surfaces.

On the required parts being assembled on the towing cable, the outer sleeve 71 is screwed into the lplug 70 and when fully home all the parts are locked together, the adjacent surfaces of the bush-and ring securely clamping the strands of the armoring. The head of the outer sleeve is preferably made of ypolygonal shape to receive a lock nut 8O adapted to fit over the head of the sleeve and to be retained in place by an eye bolt 81 screwed into the plug 70.

A In the modification shown in Fig. 2, the cable 68a is not an electrical one an-d is connected to the towed body through a cutter comprising jaws 118, 119 and mounted of the towed body for the purpose of cutting the mooring rope of a mine. The modified tow anchorage 123 consists of a streamline sleeve 124: having a central bore, provided with rubberbuf'fers 125,

and a `cup 126, coned internally. The strands of the towing cable 68a are opened' out and then bent back on themselves. lf desired the inner strands may be removed for any desired distance. The coned `cup is then pushed up until all the wires are inside and the interior filled with liquid metal such as white metal. Resin is preferably added to the cup, to prevent sticking of the white metal to the sameso that the cone shaped pudding 127 on the end of the cable is free to rotate in the cup.

The sleeve 124 isscrewed on to a plug 128 which is secured by a bolt 129 to a shackle-180 which in turn is secured by a bolt 131 to the eye plate 122, the two bolts being arranged at right angles so as to permit of universal movement between the tow anchorage and the cutter block of the para- 1 vane. rThe end of the sleeve 124 remote -from the anchorage is cut at an ,in-t

cline to permit the mine mooring passing readily from the towing cable to the anchorage without encountering any obstructions, the other end of the anchorage being arranged and constructed to prevent any obstruction arising to the passage of the mooring of the mine along the' anchorage into the cutter jaws.

What I 'claim and desire to secure by Letters Patent of the United States is 1. A towing anchorage for a cable at-y tached to a towed body, comprising a member secured to the towed body, through which member the end 'of ythe cable is passed, a coned sleeve, means for gripping the strands of the cable against the said sleeve on opening o ut and bending back the said strands, and -a resilient buffer."

2. In a towed/ body provided with an explosive charge and towed by an 'armored 4can pass, .an outer sleevesecured' to the said member, a rotatable inner sleeve, a

electric cable, Ya tow anchorage for the 'said resilient buffer, a splicing bush and a splicing ring having divergent and convergent` adjacent surfaces, the splicing ring being provided with holes through which the strands of the 'armoring are passed and bent back.
