Abstract of Patent No.4850, granted to C. A. McEvoy, of London, for: 'In torpedoes which are exploded by the bending of a soft metal tube or case containing a liquid inclosed in a vessel of glass, the soft metal tube is connected by a chain with an external weight arranged to be displaced by the collision of a ship or vessel with the torpedo. In a torpedo ignited by an electric fuze, a vessel containing the exciting fluid is fractured by the collision. In torpedoes exploded by the displacement of an external weight, the weight is secured with a cover of papier-mache which remains rigid until softened by prolonged soaking in the water. The weight is connected with a hook sliding in a guide and engaging with the stem of a striker supported by a spring. In torpedoes fired by an electric current, the end of the cable is secured in a ferrule from which the extremity of the cable core projects; the ferrule is secured and held by a water-tight joint in the base of the fuze chamber.'
