Definitions

  • the present invention relates to a pivot gun in which the pivot carrying the upper carriage can be given an inclination relatively to the lower carriage, in order to adjust the pivot vertically s, in space.
  • the object of the present. invention is a pivot gun, whichy has av notably smaller firing height and: thus greater stability.
  • This object is obtained by connecting the upper carriage to a sleeve whichis mounted for rotation on a pivot, the latter, preferably near its lower extremity, being; suspended from the lower carriage by means of a Cardan joint or the like and beingy provided at its lower extremity with lateral arms rigidly fixed to it and adjustably connected to f the lower. carriage.
  • the invention further provides that in any position of the lower carriage on the ground, which carriage advantageously is constructed as a cruciform carriage, the required angle of inclination to be given to the pivot is adjusted by means of shortest possible screw spindles, by displacing saidv lateral rigid sleeve arms by an angle relatively to two adjacent legs of the cruciform lower carriage, preferably by'an angle oi 45 der grees.
  • Figure 4 is a vertical section on line IV-IV, Figure 5, of a carriage forming the first embodiment correspond-ing to the structure according to Figure 3,v
  • FIG. 5 is a top view, partly in horizontal section on the line V-V of Figure 4,
  • Figure 6 is a vertical section on the line VIA-VI ofv Figure 5
  • Figurer? is an illustration serving to disclose (Cl. kS9--40) the second embodiment and showing schematically two different positionsv of the cross carriage onl the ground,
  • Figures 10y andi 1l are.l perspective schematic views of the carriage according to thesecond em-A hodiment, in the, two positions of Figure 7,
  • Figure 12 is a top view, ⁇ partly in section, of
  • the pivotal column II on which the gun is slued has at its lower end an external flange I2 which is provided with axially-directed extensions I3, see Figure 4, and stiffening ribs I4.
  • the flange I 2 has fixed to it a short tubular piece I5, outwardly anged at its upper end, and two angle irons I5, all of which elements together form the bearings on ring I9 for the two other trunnions I1, disposed 90 apart from trunnions 9 and by which pivotal column I I is journalled in the Cardan ring I0.
  • TheI pivot column I I has further rigidly attached to it two radiallyA extending arms which include an angle of 90 and are formed by vertical sheet metal plates I8 welded to the periphery of extensions I3 and by rigid angle iron braces I9 to the upper portion of tubular piece I5. These arms I8, I9 thus form each a fork, the two prongs of which are fixed to the column above and below the Cardan journal 9, I1, respectively.
  • the walls I8 and angle irons I9 of each arm jointly support at their outer ends a sleeve 20, the sleeveof each arm having journalled in it a stud 2 I.
  • This stud has a bifurcated outer end within which is supported on horizontal pivots 23 a threaded nut block 22.
  • a threaded adjusting spindle 24 passes through the nut block 22 and is mounted in its turn for rotation in a block 25 Cardanically but non-shiftably suspended from the lower carriage. At the top the spindle 24 carries a hand wheel 2G.
  • the upper carriage is mounted on the pivot I I by means of a sleeve 21 and two antifriction bearings 28 and 29.
  • a ball thrust bearing 39 takes up the weight of the upper carriage and of'all parts carried by the latter.
  • the upper carriage comprises a box 3l' which by means of horizontal plates 32 and vertical plates 33 is connected to the sleeve 21.
  • This box carries lateral carriage walls 34 on which are provided the bearings for the horizontal gun trunnions 35.
  • the elevating gear of the gun is marked by the toothed arc 36 and pinion 31.
  • Lateral training is effected by an internally toothed wheel 38 fixed on the flanged portion of tubular piece I5 and in mesh with a pinion (not shown) mounted on the upper carriage.
  • the Vhereinbefore described carriage constructed according to the invention shows, when compared with the known type of carriage, the further advantage, ⁇ that the diameter of the internally'toothed wheel 38 of the training mechanis'mA caribe-made very large without interfering in any way with other ⁇ parts of the carriage.
  • the .power for operating the carriage upon' training therefore, can be kept small.
  • Case I in connection with the first embodiment will be considered iirst by reference to Figure 8.
  • turning of the carriage about the axis X--X is obtained by that leg which extends in the direction of the inclination, being lifted by the amount a, while the legs extending transversely of the former are lifted each by the amount Therefrom results Yan inclined position of the plane of the legs relatively to the ground, the angle of which position can be calculated from tang the inclination thus assumes the value a, (i342 y
  • the maximum inclination (a) that can be obtained with the given amount a thus does not lie, generally spoken, in the direction of the legs, as in Case I, but between the legs.
  • a determined limit value of the inclination of the ground can be compensated at any rate, for instance a limit value prescribed by the user, no matter in which position the carriage may be relatively to the ground, that is in the position of Case I, Case II or in an intermediate position.
  • This limit Value which is obtained at any rate by the amounts a and b, is +5 in the rst embodiment,
  • This second embodiment is illustrated in detail in Figures 12 and 13. It differs from the rst-described.I embodiment merely by v,the azdjusting: arms being angularly displaced relatively: tothe legs of. the lowery carriage.
