Definitions

  • the hydrostatic depth setting devices 'ofthe mines cannot be altered from the interior of the submarine after the mines have been placed in position in the open laying. tubes or chambers, so that the depth setting devices must be finally set before the mines are placed in the" tubes or chambers and the submarine departsfor its objective.
  • the regulation of the hydrostatic clepth s'etting devices of the mines is effected whenthe latter are in position in the open laying tubes or chambers, by means of 'leompressed air controlled from-aposition withinthe submarine.
  • the chambersof the hydrostaticdep'th' setting devices are connected'bymeans of 'a length of external tubing to a'suitableconnection which passes through the ipressure hull of the submarine andis connected to -tubing withinthe submarine whichlatter tubing is led to the controlpos'ition 'and is supplied with "compressed air, Itis evident that by raising or lowering the pressure ,of the air by suitablemean's at the control position the hydrostatic depth setting devi'cesican be ad ⁇ justed to regulate the depth setting of.
  • a valve inside the pressure hull is closed so as to' cut off the supply of compressed air.
  • a suitable isolating valve may be fitted on each mine between the hydrostatic device and the aforesaid external tubing so that when a mine is dropped from the laying tube the'following actions occurz-(l) After the mine i'sreleased and drops a short distance a lever appertaining to the isolating valve engages a projecting piece in" the laying tube in order to cause the valve to close and cut off communication to the hydrostatic device and (2) after the mine has dropped a further suitable distance the ex ternal tubing is disconnected from the casing of the isolating valve and the mine then dropsfreely.
  • the hydrostatic depth setting device on each mine may also have a mechanical setting so that a depthregulation may bejmade before placing, the mines in the laying tube or chamber.
  • a depthregulation may bejmade before placing, the mines in the laying tube or chamber.
  • E represents the casing of the hydrostatic depth setting device (details of which will be hereinafter described) .which risicarried by the mineand is regulated byi-compressed air admitted through a pipe E
  • This pipe communicates with the casing F ofan isolating valve (details of which will also be hereinafter described) controlled by alever F arranged above a stop member B in the chamber B.
  • the said valve casingiiF has detach ablyconnectedthereto a length of armoured flexible tubing F the upperend of which is attached to a connection F which passes through the pressure hull A and is connected to tubing F within the submarine, the latter tubing being led to the control position and being supplied .with compressed air which thus has access tothe hydrostaticrlepth setting device E.
  • a pressure gauge F Figure 4
  • a stop valve F Figures 1 to 3 inside the pressurehull is closed so ,as 010,111 off the supply of compressed air.
  • the hydrostatic depth setting device is thus set and the mine is ready to be released.
  • the hydrostatic depth setting device Eissimilar in its broad aspecttothat forming the subject of English PatentNo. 264.973 that is to say it comprises drum E rotatably mounted within the Gasing-E and carrying an auxiliary-wire Eicon nected to the contrivance situated ,inthe anchor for stopping thepaying out of the mooring cable by the pull which is exerted s onthe said auxiliary .wire when the rotation of the drum is stopped by a locking pawl E which is moved into engagement with a lug E on the side of the drum E when the set depth is reached, this depth being determined by a diaphragm E one side of which is open to the sea and theother is acted upon by the airpressure supplied by thevpipe E
  • the said pawl E forms part of a lever Fl which is pivotally carried by a rod E con- :nected to the diaphragm E and-is acted upon by a spring E
  • a-mechanical setting is provided so that regulation
  • a movable fulcriunE 1s provided between thepivot of the lever E and the pawl E and the contiguous portion of this lever is graduated as shown to :correspond with diiferent depth settings. moving the fulcrum E towards or away from the pivot the time at which the pawl E is moved into eng ement with the lug a1n- .der the conjoint action of the spring Fi i the external sea pressure and the internal; air pressure can be varied.
  • Tl1'1S,'?LS hereinbefore referred to enablesa preliminary-depth 7 setting to be effected; by :mov-i ngthe :fulcnusn lE-"in accordance with the low tide water level at the locality where it is desired to lay the minesand the compressed air regulation is then only required to be used torgiye an equal increased depth set-tingnto all-the mines corresponding to the height of the ac tual ,waterlevel above low tide water level at the time oflaying.
  • Theisolating valve casing F contains a spring controlled valve F of disc shape adapted to bear against a valve seat situated between the compressed air inlet opening communicating with the tubing F and the on the valvecasing F in such a manner'that 5 this gland will becornepulled fromzthe socket when the mine falls 'beyondthe point at which the lever F *isoperated'to allow the valve F to move onto its seat.
  • the present invention relates only to cases where the submarine mines are carried in laying tubes or chambers which are open to the sea, as in an alternative system of mine laying from submarines in which the mines are carried inside the pressure hull and are launched in a similar manner to that employed for launching submerged torpedoes, the depth setting of the mines can be regulated directly by the personnel of the submarine up to the actual moment of laying the mines.
  • a submarine mine for use in a submarine as claimed in claim 4 comprising an isolating valve associated with the hydrostatic depth setting device and means for detachably connecting the external tubing to the casing of said isolating valve, this isolating valve being operated to cut off communication to the hydrostatic depth setting device as the mine commences to descend in the laying tube or chamber.
  • a submarine mine provided with a hydrostatic depth setting device which is adjusted by means of compressed air, a conduit leading to the interior of the chamber of said depth setting device, an isolating valve the casing of which communicates with said conduit, a second conduit leading compressed air into said isolating valve and meansfor moving said valve, when released,
  • a submarine mine provided with a hydrostatic depth setting device which is adjusted by means of compressed air, additional mechanical means for adjusting said device, a conduit leading to the interior of the chamber of said depth setting device, an isolating valve the casing of which communicates with said conduit, a second conduit leading compressed air into said isolating valve and means for moving said valve, when released, to its closed position so as to shut ofi communication to the interior of the hydrostatic depth setting device chamber.
