Abstract: 445,130. Submarine mines. RUDWANN, D., 9, Via Pomerio, Fiume, Italy. Dec. 21, 1934, No. 36614. [Class 9 (ii)] Relates to submarine mines provided with a hydrostatic device for maintaining the mine at a constant depth in a tide way, of the kind in which the hydrostat unclutches or clutches in one direction or the other a gearing between a propeller and a drum, the rotation of which in one direction or the other shortens or lengthens the effective length of the mooring cable. According to the invention, the propeller 33, Fig. 4, the hydrostatic diaphragm device 24, 26, the drum 22, and the gearing are arranged in axial alignment. The drum and the gearing are mounted in an outer casing 21, which is provided with a circle of teeth 44 in mesh with the last pinion 45 of the gearing. The gearing is carried by an internal casing 14 fast with the drum. The gearing comprises a number of pinions and worms, which can be set in rotation in one direction or the other by a dog clutch member 47 on a spindle 34 rotated by the propeller through a friction clutch 34<1>. A stop 16 is operated by the gearing to limit the number of rotations of the drum in one direction or the other, after which the friction clutch 34<1> slips. The propeller is rotatably mounted on a pivot 57 projecting from the drum 22 ; and the hydrostatic device comprises two diaphragms 24, 26 arranged between perforated walls in the hub of the propeller and containing lubricating oil between them. External pressure acts through holes 23 on the diaphragm 24 and is transmitted by the lubricating oil to the other diaphragm 26 controlled by a spring 28, and connected by the friction clutch 34<1> to the spindle 34. All the parts of this mechanism are filled with lubricant. The mooring cable is paid from the drum over guide pulleys 42, 41, 40. A short length of cable is kept slack before the mine is laid and the end of this slack part is attached by a link 36 to a spring bolt 35. The outer casing 21 of the apparatus is attached at two points 19, 20 to a short auxiliary cable 6, Fig. 1, including a shock absorber 3 and a swivel 2 and connected at its other end to the shackle 1 of the mine A. Before the mine is laid, the cable 6 lies over a projection 1<1> on the mine, and the casing 21 of the depth controlling device is held tight at the side of the mine or between the mine and its anchor B, a cork seat 4 being provided for it. A short time after the mine is dropped into the sea, a releasing device 8 frees it from its anchor, the mine rises, the auxiliary cable 6 falls off the peg 1<1>, and the depth controlling device takes its position below the mine as shown in Fig. 2. Then, after a partial rotation of the drum 22, a finger 43 on the spring bolt 35 escapes through a notch in the flange of the drum, the bolt release the slack length 10 of the cable, and the parts assume the operative position, Fig. 3. Specification 129,018, [Class 9 (ii)], is referred to.
