Definitions

  • the chief object of the present invention is" to provide an improved arrangement-j for actuating the safety device or devices in which the d1a'-" phragm is not subjected to theafor'esaiding lever provided at its rocking point with Patented May 15, 1928.
  • This, invention relates to submarine mines of"the kind provided with one or; more safety devices controlled by the tension of the mooring cable.
  • the safety devices have been actuated by a slidlng rod which 7 passes into the flotation chamber or mine proper and is connected directly or indirectly to the mooring cable and; the con-- sequent movement of the said rod has necessit'ated the provis'ion of a watert ght 'dlalarge' movements and can thereforebe made of sufficientrigidity and strength to with-' standthe high hydrostatic pressures obtaining when the mine-during the anchoringop+ eration descends to every considerabledepth beneath the surface of the water.
  • the aforesaid sliding-rod is replaced by ajfrockthe aforesaid diaphragm which, therefore, partakes only of the rocking'movements of the said lever.
  • Thi"s, lever is suitably connected to 'the mooring'cableandalso to the safety device or devices which, in the Case of a mine that isfi'red electrically when one or other of a number of horns on the exterior of thefmine is struckby a passing ve s sel, comprise a safety switch arranged in the Circuit of the battery, which circuit in-'" cludes the detonator, and a trigger or release ingdevice that normallyholds the primerof the mine at a safe distance from the" detonator and when moved into the disengaging position allows the primer todrop into the operative position in relation to the deto nator'.
  • rockinglever ma y be held in. the inoperative position' by a delay'action' device; which L prevents the said, lever from being moved to close the switch and move the trigger to the releasing positioni'u'n'til after the lapse of'a predetermined interval of ti me from the moment of separation of the flotation chamber from thefanchor'.
