Shock hardening device for torpedo-mounted dispensers on torpedoes

Three extender assemblies are mounted on the torpedo-mounted dispenser (TMD) of a torpedo to provide shock hardening of the TMD. In a first embodiment, the extender assemblies consist of short sections of metal tubes mounted on inner plate portions. The inner plate portions are bent to conform to the TMD radius and attach to the TMD such that the metal tubes are aligned longitudinally on the TMD. Outer plates are attached to the tubes and are in contact with the dolly used to support the torpedo and TMD. When the dolly the TMD is subjected to a shock load, the tubes deform to take up shock loads applied to the TMD through the dolly. To attach the assemblies to the TMD, slots on each inner plate are positioned over hooks on the outside surface of the TMD. The hooks are part of the TMD assembly and serve to secure o-ring or spring retainers for the cable within the TMD. An eye bolt fits over the hook and is bolted to a bent tab on the inner plate. To facilitate loading of the TMD into or out of the dolly, the ends of the tubes and plates are chamfered. In a second embodiment, the tubes are aligned circumferentially about the TMD.
