Definitions

  • This invention relates to a method of. and apparatus for directing gun fire and has for its main object to provide a quick and simple means of concentrating the fire of a plurality of dispersed guns on to a common target.
  • apparatus for directing the fire of a plurality of dispersed guns on to a common target from a control position comprising a device on which the relative positions of the pivot guns of the dispersed troops are adapted to be plotted, and which is so arranged as to be set according to the direction of the target for the control position, meansbeing provided which is arranged to cooperate with said device in such a way as to be set according to the range of the target for the control position and which is so constructed as to indicate the directions and ranges of. the target for each of the pivot guns oi the dispersed troops.
  • the device on which the relative positions of the pivot guns are adapted to be plotted comprises a transparent or translucent window which is superimposed upon a setting scale indicating angles and distances from the control position, means being provided for rotating said window to a position determined by the direction of the target from the zero line of the control position, and for replacing said setting scale by a degree fan so marked as to indicate the direction and range of the target from each individual pivot gun from the gun markings plotted upon said window.
  • Figure 1 is a plan view of an apparatus for directing gun fire constructed in accordance with the invention.
  • Figure 2 is an end view of the apparatus shown in Figure 1.
  • Figure 3 is a view from the underside, while Figure 4 is another plan view showing the scale for taking readings moved into another position.
  • the apparatus which will be referred to hereinafter as the plotter is constructed in the form of a hollow rectangular shaped box I, which is constructed of metal or any other hard material and has a hinged transparent lid 2, and a hinged opaque base 3, both the lid and the base being normally retained in the closed position by means of lugs or projections 4 and 5 which engage behind the periphery of a knurled retaining wheel ii which is provided with a slot 1 for enabling either the lid or the base to be lifted when the wheel 6 is rotated to such a position as to enable the lug 4 or 5 to pass through the slot 1.
  • a metal retaining strip 8 having a longitudinal groove in which is slidably mounted a flat metal plate 9 having a circular opening in which is rotatably mounted an annular member it on which is marked a degree scale and which carries a transparent or translucent sheet of material, the latter being held in position by a spring ring ll. 1
  • This annular member together with the transparent sheet of material forms a rotatable window, and the degree scale co-operates with a zero mark l2 on the plate 9 so as to enable the annular member ill together with the transparent sheet ofmaterial to be rotated through any required angle from a zero line up to a predetermined angle, for example, in either direction.
  • Slidably mounted beneath the window is a chart 13 which is stretched between two rollers or spools l4, I5 much in the same way as a film is mounted in a camera so that by means of two control knobs l6, 11 external to the box casing the chart can be wound from one roller on to the other so as to cause the chart to move underneath the transparent window into any desired position.
  • the chart is formed in two sections comprising a setting scale H!
  • the left hand side'of the casing l is provided on its upper side with a pair of spring clips 20, 2
  • the underside of the base 3 is'provided with a flat spring loaded retaining member 35 for holding a supply of discs of transparent or translucent material 35 for use in the annular member Ill.
  • the method of operation is as follows:
  • the centre of the setting cir- I cle is assumed to be in the middle of the window, this is not essential and the carriage 9
  • the angle from the zero'line of this gun (which is known as the control pivot gun) to the other troop pivot guns together with the distances of such troops from the control pivot gun are measured or estimated, and the chart is set with the control pivot gun at the centre of the setting circle.
  • the annular member in together with the window is rotated through a radial angle corresponding to the angle between the director zero line and the line gun target, commonly called the angle from zero line and the carriage 9 is moved sideways if necessary'so that the mark on the window representing the director, or the control troop pivot gun is over the centre line of the range and line chart.
  • the chart is then wound by the control knobs I6, I! until the range of the control troop pivot gun as indicated by the degree fan is disposed under the mark on the window representing the. position of the director or the control troop pivot gun.
  • the plotter constructed in accordance with the invention may have other uses beyond those described above, for example, it may be used to discover the relative positions of troops concealed one from the other. In order that this may be effected, all troop pivot guns are ranged on a common target, and their positions are plotted on the window of the device, the range and line portion of the chart being used. The setting circle is then arranged under the window, and the relative positions of the troops recorded. In this case further concentrations may be carried out, the approximate troop positions thus found being used until more accurate information is available.
  • Apparatus for directing the fire of a plurality of dispersed guns on to a common target from a control position comprising a setting scale indicating angles and distances from the control position, a Window on which the relative positions of the pivot guns of the dispersed troops are adapted to be plotted superimposed upon said setting scale, means for rotating said window to a position determined by the direction of the target from the zero line of the control position and means for replacing said setting scale by a degree fan so marked as to indicate the direction and range of the target from each individual pivot gun from the gun markings plotted upon said window, and means slidably mounting said window with respect to said setting scale whereby the position plotted for any one of the dispersed pivot guns may be employed as the control position;
  • Apparatus for directing the fire of a plurality of dispersed guns on to a common target from a control position comprising a setting scale indicating angles and distances from the control position, a window on which the relative positions of the pivot guns of thedispersed troops are adapted to be plotted superimposed upon said setting scale, means for rotating said window to a position determined'by the direction of the target from the zero line of the control position and a degree fan provided with radius range marks, said setting scale and said degree fan being formed on a piece of flexible sheet material stretched between a pair of rollers or spools whereby said setting scale may be removed from said window and its position occupied by said degree fan which is so marked as to indicate the direction and range of the target from each individual pivot gun from the gun markings plotted upon said window, and means slidably mounting said window with respect to said setting scale whereby the position plotted for any one of the dispersedpivot guns may be'em ployed as the control position.
