Definitions

  • This invention relates to such an apparatus for the electricaldistance control of the valve gear of a hydraulic gun pointing mechanism which first enables the gun barrel to 'be adjusted in a manner which is -specially accurate and free from shock and secondly difiers from other apparatus for the electrical long distance control of the valve gear of a hydraulic gun pointing mechanism by the fact that its valve gear takes up a considerably less amount of space.

  • the above mentioned long distance control apparatus contains a transmitter K mounted at the observing station (see Fig. 1) which is constructed in the .usual way so that the continuous current supplied to it by conductors (not shown) is converted into three dephased currents of variable strength. These three dephased currents of variable strength are conveyed by a three-phase long distance conductor 70 to the receiver F which is constructed as a synchronous motor, the said conductor 12 being excited from the continuous current main J.
  • the transmitter K is adjusted by a milled head 10 and a hand wheel I0 each of which is positively connected to a middle wheel 10 and I0 of a gun planet gear in the manner shown in Fig. 1.

  • the adjusting apparatus rotated by the hand wheel is positively connected to a telescope 74 which oscillates about a horizontal axis and is used when it is desired to eliminate the influence of an oblique position of the ship (e. g. when rolling or pitching) on the elevation imparted to the gun barrel with respect to a horizontal plane.
  • the gearing which is intended to connect the piston rod C of the controlling valve to the receiving motor F and the gun barrel A and substantially inclosed by the casing E is shown in Figs. 2 and 3. It contains two worm gears 6 e and 6 e mounted in the casing E and. of which the one 6 e is positively connected through a gearing e f with the shaft f of the receiver F (see also Fig. 1) and the other through a gearing c.
  • the two worm gears are connected 'by a sun and planet gear 6 6 with an ap paratus which regulates the stroke of the piston rod C of the controlling valve B and which is-hereinafter termed the stroke apparatus.
  • This stroke apparatus contains a drum 6 which rotates with its shaft e in the casing E and the axis of rotation of which coincides with the common axis of rotation of the worm Wheels e and c and 'is provided on its outside with a rib e in the form of a helix.
  • This rib 6 has on the part which extends over the one half of the length of the drum a greater external diameter than on the part which extends over the other half.
  • the transition from the one diameter to the other is formed by a transition are e fi which extends over only a comparatively short part of the'rib e against the rib 6 lies a roller 03 which embraces it laterally and which is movable longitudinally on a bolt 05 running parallel with the axis of rotation of the drum 6.
  • the bolt 03 is fixed to one forked lever arm D of a double-armed lever which is pivotally mounted on the casing E about an axis which is likewise parallel with the axis of rotation of the drum and the other lever arm D thereof carries, on the part which protrudes from the casing, the toothed sector d already mentioned which cooperates with the toothed rack c of the piston rod C.
  • the lever arm D is under the action of a tension spring 03 which tends to rock the lever D D in such a'way that the roller 612 bears with pressure against the rib e.

  • the shaft f and with it the drum e of the stroke apparatus is set in rotation through the medium of the gearing f 6 e e e 10 11 direction of'the arrow y (see Fig.
  • This latter therefore passes first from the pipe 6 into the'part of the pipe 6 in front of the cut-0H device G through the lower part of the opened cut-ofi devlce G, the adjoining part of the pipe 6 and the pipe a into the cylinder A
  • The-piston a consequently rises andimparts to the gun barrel A an elevating movement.
  • the water displaced by the piston 11* flows away at the same time through the pipe at and the waste water pipe a opened by the cut-off device G.
  • the ratios are so determined that the movement of the gun barrel takes place at a moderate speed.
  • the piston valve 0 of the controlling valve B begins to admit the water under pressure from the pipe 6 through the passage 6 into the pipe a
  • The'piston 0 simultaneously opens the passage 6 leading to the waste water pipe, so that the water displaced by the piston a? now also flows away through the waste water pipe a b.
  • a principal advantage of the apparatus which forms the subject matter of this invention is that the gun barrel can be moved into the position required by the ad ustment of the transmitter with great accuracy and free from shock.
  • the controlling valve only exerts an accelerating or retarding action on the movement of the gun barrel,'whereas rapidly closing cut-ofi' devices are the controlling factors for the beginning and above all the end of the movement of the gun barrel, and it is not necessary, to construct the controlling valve as an accurately working element.
  • the laps may therefore be so widel chosen that small variations in the position of the controlling edges or an unavoidable wearing of these edges do not prejudicially afiect the accuracy of the adjustment of the gun barrel.
  • the fact that the lappf the valves may be of large dimensions and that an accurate adjustment of the controlling valve is not necessar permits in its turn of making the app iances which serve to return the controlling valve considerably smaller than if an accurate adjustment of the controlling valve were necessary.
