Definitions

  • This invention has for its primary object to provide improved mechanism for steering torpedoes, or other self-moving weapons, against a ship or moving target after it, shall have passed through a wake or a like abnormally disturbed condition of the water.
  • the invention also resides in an improved wake-controlled mechanism for increasing or ac'centuating a deviation in a particular direction to steer a torpedo against a moving target.
  • Figure 1 shows the path of .a torpedo passing astern of a ship and returning upon it;
  • Figure 2 shows the improved self-steering device controlling the direction rudder under the influence of a rotary movement around an axis
  • Figure 8 shows a self-steering device con trolling the direction rudder under the combined effect of two concordant and contemporaneous rotations around two different axes
  • Figure 4- illustrates the manner of connecting the constructionof Figure 3 to a gyroscope Figure 5, shows the construction of Figure connected with a gyroscope;
  • Figure 6 shows a detail of the connection with the gyroscope
  • a self-steering device of'the type which operates under the effect of the rotations around one axis, for instance the course deviation, on entering the wake or the heeling movement, is shown in its general arrangement in Figure 2.
  • the device includes a fluid pressure or servo-motor O for controlling the direction rudder connected in the usual way with the slide valve A controlled by the gyroscope 0 ( Figure 5) of the usual gyroscopic steering-gear.
  • the controlling gear of the direction rudder is connected at e to the rod f of a piston 26 operating in the cylinder 9 of the servomotor C.
  • the fluid pressure is admitted to this cylinder through the two conduits a a after passing through the inverting device D from cylinder in of the distribution valve A, in which latter-cylinder operates, in the usual way, two valves 7' j, connected by a rod 1 to the gyroscopic steering gear 0.
  • Figure 5 is shown the horizontal ring A the vertical ring A and the revolving mass M, the direction of movement of the torpedo being indicated by arrow N.
  • a forked lever if which with its fork engages a pivot 25 borne by the vertical ring A as is better shown in Figures 5 and 6 where 0 indicates the rotation axis of the vertical ring.
  • the two links cl, d which by means of connections r, 7" transmit to rods 1 and i of the valves B and A the path oscillations.
  • conduit a in communication with conduit a, or con-' duit' (1,, the pistons p, and p covering the openings 5 andb of conduit 6 in the valve B.
  • torpedo enters the wake andunder'goes a'brusque and violent deviation either piston p or 9, uncovers also the respective port Z), 6 to admit compressed air from conduit '0 into'con'duit' b and the cylinder is. This results inthe piston Z being forced tothe left against spring m.
  • Piston Z is provided with two crossed channels 8 which when thepiston'is in its extreme left position, cross or invert the communications between cylinders h and 9, so thatpiston u, insteadof rectifying the torpedo, willjact to amplify and maintain the direction taken by the torpedo, bringing it upon the path which will lead it back against the ship attacked.
  • the apparatus besides the inverting device Dsimilar to that of Figure 2, the usual distribution valve A, and the rod z' of whose doublep'iston is-connected to the gyroscope of theordinary gyroscopic Steering device as shown 1n Figure 2, includes also two slide valves of the self-steering device," one B, thep iston .rod g of which'is also connectedtothe gyroscope of thelgyroscopic steering device in the manner; al ready shown fo'rslide valve ⁇ 3' in Figure 2, and one B"control'led'"by' the rolling gyrob are arranged in series in the compressed air conduits Z), and Z/ from conduit 0 or a and there'fore both rods q, 9 must be simultaneously shifted to a sufficient extent in order that the compressed air may have free passage through this way.
  • a torpedo steering mechanism coinprising a rectifying motor and means operable by an abnormal deviation of the torpedo for reversing the action of the motor to increase and maintain the deviation.
  • a rectifying motor means for admitting compressed fluid thereto for operating the same upon a deviation of the torpedo, and a reversing gear operable upon an abnormal deviation to reverse the action of the motor.
  • a rectifying motor for admitting fluid pressure to the motor for operating the same upon deviations of the torpedo to return the latter to its proper course
  • a reversing gear interposed between the valve and motor for reversing the action of the latter
  • a gyroscopic controlled valve operable upon a brusque deviation of the torpedo for admitting air to the reversing gear to render the same operable.
