Definitions

  • the said mechanism consists of a cylinder 4 containing a piston 5, which by a bell crank lever 6 and a link 7 is connected with 1a diaphragm 8 or the like exposed, at the outerside, to the water pressure.
  • Opening into the cylinder 4 behind the piston is a piping 9 for a suitable pressure medium, as for instance a liquid'contained in a receptacle 10 and acted upon by the pressure of a gas adapted to be supplied from without by a pump or from a compressed gas receiver before launching the floating body, or to be supplied from a com pressed gas receiver located in the floating body.
  • a suitable pressure medium as for instance a liquid'contained in a receptacle 10 and acted upon by the pressure of a gas adapted to be supplied from without by a pump or from a compressed gas receiver before launching the floating body, or to be supplied from a com pressed gas receiver located in the floating body.
  • a slide valve 11 Serving as a member controlling the supply of pressure medium to the cylinder 4 is a slide valve 11 movable in a valve chest, or a three-way cockor the like controlled'by the hydrostat 2 12 denotes a piping leading from the liquid receptacle 10 to the slide valve, and 13 denotes a discharge piping adapted to discharge liquid from the cylinder 4 into the interior of the floating body or, if desired, into a separate container.
  • the slide valve 11 is also con trolled indirectly by the piston 5, which is connected with a rod or a frame 14: forming a support for the inner'end of the spring 3. On account thereof the tension of the spring depends on the positionof the piston 5, and
  • valve channel 15 Fig. 2 occupies a middle position between V the ports devised in the valve chest for the pipings 12 and 13.
  • V The device described operates as follows, it being supposed that the floating body from the beginning is in equilibrium at a certain depth of submersion.
  • the cylinder 4 is in part filled with liquid and keeps the diaphragm 8 in such a projecting position, that the specific weight of the floating body corresponds exactly to the specific weight of the surrounding water.
  • the diaphragm 2 occupies a middle position and-the slide valve is in inoperative position, as in Figs.
  • the said spring tends to move the diaphragm 2 back to the cific weight takes place.
  • the piston 5 decreases the tension of the springB and, owing thereto, tends to interrupt indirectly the connection between the cylinder 4 and the discharge piping, since the water pressure, on the decrease of the tension of the spring 3, is anew capable of moving the diaphra 2 and the slide valve' 11 back to their middle positions.
  • Themovementof-theplate 29 is efiected'bythe mechanism serving to 7 hange the specificweightof the fioatingij body, for instance by: the plate being connected by meansof ali-nkBO' and a bell crank 9n; lever 31with the thlieadedstem 18. r 7
  • Thefloating body shown in Fig. 5 differs from that shown in Fig. 3 only in'that the pressure acting upon the liquid contained in the receptacle 10 is eflfected by means of a piston 33 actuated by a spring motor 32 instead of by a compressed gas.
  • the spring motor 32 which may be wound up by means of a crank placed on the pin 34 is by suitable means connected with a nut in the form of a toothed whee-l, said nut be ing screwed onto the threaded rod 36jof the piston 33 thus servingto move the piston forward, according as the liquid under pressure is consumed.
  • the construction and manner of operation of the controlling mechanism proper are similar to those of the embodiment shown in Fig. 3.
  • the invention is not limited to the constructional details shown in the drawings, but may be varied in many different manners.
  • a piston or a receptacle connected with the outer water or any other suitable device.
  • a slide valve shown in Fig. 1 may be substituted a. three-way cock, and forthe same valves shown in Figs. 3 and 5 may be substituted two valves placed one above the other or a three-way cock having a pivotally mounted casing, the hydrostat actuating in the two latter cases the one member for opening the connection to or from the working piston, while the other member is actuated by the device changing the specific weight and serves to interrupt the connection.
  • a submarine floating body adapted to assume a position of equilibrium at a certain depth of submersion, comprising means for changing the specific weight of the body consisting of a movable member adapted to be actuated in one direction by the outer water pressure, a liquid pressure cylinder, a container for liquid under pressure, a hydrostatic device, and a member controlling the supply of liquid from said container to the cylinder and its discharge from the cylinder, said controlling member being actuated in opposite directions by the hydrostatic device and the means for changing the specific weight of the body and means for varying the normal effective force of the hydrostatic device.
  • a submarine floating'body adapted to assume equilibrium at a certain depth of submersiomcomprising a hydrostat, a motor opposing the operation of the hydrostat, resilient means between the motor and bydrostat to permit compensating movements of either, and displacement varying means operated by the motor.
  • a submarine floating body adapted to assume a certain depth of submersion, comprising a hydrostat,:r motor opposing operation of said hydrostat, resilient means between them, a valve operated by the differential movement between said motor and hydrostat and controlling a supply of motive fluid under pressure to said motor, and displacement means operated by the motor.
  • a hydrostat means for'varying the specific weight or" the said floating body
  • a connection between the said hydrostat and the said means comprising a movable member, the movements of which are controlled by the cooperation of the saidhydrostat and the specific weight varying means
  • a yielding device interposed between the said hydrostat and the specific weight varying means, said yielding device cooperating to control the action of the said hydrostat.
