Definitions

  • he present invention relates to subfloating bodies, such as mines, torpedoes, and the like, which, after having been launched, are adapted to perform an oscillating movement about a position of equilibrium below the surface of the Water.
  • a depth-regulating chamber provided in the body and adapted to be filled and emptied alternately under the control of a hydrostat or by means of a screw likewise controlled by a hydrostat.
  • a source of power is provided which in known apparatus of this kind consists of a gas producer, a gas accumulator, a source of electric energy or the like.
  • 1 designates the chamber containing the explosive charge.
  • the toothed wheels 6, 7, 11 are supported by a lever 13 swingably mounted on the shaft of the toothed wheels 4, 5' and connected to a well known hydrostat 14 which acts on the lever 13 so as to bring the wheel 7 in or out of engagement with the rack 81.
  • a projection 15 is provided on the air-brake, said projection striking, when the wheel 7 is disengaged from the. rack, a fixed abutment 16 which thereby prevents further movement of the air brake and thus of the spring motor.
  • the rod 8 is guided at the upper end of the channel 9 by spring actuated levers 17 which are placed in such position that they retard the inward movement of the rod 8.
  • the mine described above operates as follows: The mine is adjusted in any suitable manner so that it will descend in the water, contracted, but will ascend in the water, when the bellows are pressed outward. Before the launching the bellows are contracted and the spring motor is wound completely and stopped in the manner above described. The mine, when launched, will thus begin to descend immediately.
  • the hydrostat 14 is actuated by the water ressure, thereby causing the toothed wheel to engage the rack 81, and, at the same time, bringin the projection 15 out of engagement with the abutment 16 so that the spring motor is released. Under the influence of the spring motor the rod 8 will now move downward the speed of this movement being previously adjusted by means of the braking device 12.
  • the bellows 10 are thus pressed outward, therebyincreasing the entire volume of the mine so that the mine becomes lighter than the water displaced, ceases to sink and commence to move upward.
  • the construction of the mine may be modified in difierent manners by the equivalents of the form shown.
  • other means than the to effect the variations of volume of the mine, and the oscillating movement thereof such. as for instance a piston reciprocating in the channel 9 or a screw, and in the latter case a rotary shaft is'provided instead of the rod 8 the rotation of said shaft taking place under the control of the hydrostat when the subfloating body reaches its uppermost or lowermost-positions in the water.
  • the principal feature of the invention consists in the arrangement of a spring motor as the driving device.
  • a spring motor means acted upon by said motor to cause the bellows may be used body to move up and down in the water, and a hydrostatcontrolling the operation of the spr1n motor.
  • a subfloating body adapted to perform an oscillating movement about a position of equilibrium below the surface of the water, the combination of a spring motor, means acted upon by said motor for varying the volume of the subfloating body, and a hydrostat controlling the operation of the sprinfimotor.
  • a subfloating body adapted to perform an oscillating movement about a position of equilibrium below the surface of the water, the combination of a hydrostat, a spring motor, bellows actuated by said motor vand the outside water, and means connecting said spring motor and bellows under the control of the hydrostat.
