Definitions

  • the present invention relates to a loading device for a gun, particularly for a motorized gun such as a gun mounted on a track-laying vehicle.
  • a principal object of the present invention is to provide a novel and improved loading device for heavy caliber guns in particular for guns mounted on track-laying vehicles, which permits a considerable increase of the rate of fire in comparison with the rate of 'fire obtainable by hand loading.
  • the term heavy caliber as used herein is not intended to designate a definite range of caliber but refers to shells the length and weight of which is such that they are not conveniently suitable for automatic feeding and ramming by means of a magazine of the type used for automatic guns of small caliber.
  • Another object of the invention is to provide a novel and improved loading device for guns of the general type above referred to, which is semi-automatic in that the feeding and ramming operations are eifected by the control of power drive means thereby relieving the gun crew of a substantial part of the heavy manual labor usually connected with the servicing by hand of guns having a fairly heavy caliber.
  • Still another object of the invention is to provide a novel and improved loading device for guns of the type above referred to, which does not interfere with traversing and elevation or depression of the gun barrel and which is operable in different elevational positions of the gun barrel.
  • Fig. 1 is an isometric view of a track-laying vehicle mounting a gun equipped with a loading device according to the invention.
  • Fig. 2 is an isometric fragmentary view of the loading device and the. gun in one operational position.
  • Fig. 3 is a similar isometric fragmentary view but show- Vehicle.
  • Fig. 4 is an isometric fragmentary view also similar to Figs. 2 and 3 and showing the loading device and the gun in still another operational position.

  • the elevator serves to receive a number of shells or rounds 14, side by side, and has at its outer end an opening 8 for feeding the shells, one by one, into the elevator.
  • the shells are elevated within the elevator by means 'of' two lower rails 9 and 10 and two upper rails 11 and 12; 1
  • Each rail is provided with spring actuated stops or catches 13 so spaced that the shells can be placed between the stops as can best be seen in Fig. 3.
  • .By means of a power drive reciprocatory movements are imparted to the rails so that shells placed in the casing through opening 8 are lifted upwardly, step-by-step.
  • the stops of the stationary rails must be so arranged that they permit a passage of shells in upward direction but not in downward direction.
  • the upper or discharge end of the elevator is preferably secured to the cradle in which the gun is carried on the The discharge end of the elevator feeds the table 15.
  • Loading table 15 is pivotally mounted on pivots 16 which may be part of the trunnions about which the gun barrel is elevated or depressed. In any event, pivots 16 should be disposed coaxially with the elevational'axis of the gun.
  • a retaining means shown as a spring actuated stop 17 which yieldably limits vertical displacements of a shell resting on the loading table.
  • a pivotal retaining means in form of a second stop 18 is provided at the rear end of the loading table and serves to prevent an axial displacement of a shell relative to the loading table.
  • stop 18 comprises a bifurcated portion which in the pivotal positions of Figs. 3 and 4 engages the flange of the cage of a shell and in the pivotal position of Fig. 2 is disengaged from said flange thereby permitting axial displacement of the shell as will be more fully explained hereinafter.
  • the pivotal position of stop 18 or more specifically of its bifurcated portion is controlled by means of an arm 19 which in turn is actuated by the pivotal position of loading tray 4.
  • Loading table 15 is pivoted about its pivots 16 by means of a hydraulic power drive 20.

  • This power drive is in communication with manifold 23 by pipes 32 and 33 and can also be con-- trolled from the aforementioned central control point.
  • Power drive 31' serves to turn flange-30 about a bearing shaft coaxial with tube -28 thereby effecting a pivotal movement of loading tray 4 about an axis parallel to the axis-of the barrel.
  • a piston rod 34 is disposed within the loading tray, extending through both the casing portion and the tubular portion-thereof.
  • One end of rod 34 is'secured to casing bottom 27 and a cylinder 35 is fitted axially slidable upon rod 34.
  • the end of cylinder 35 facing casing bottom 27 mounts an arm -39'-the free end of which is laterally extended to form a push member 40 engageable with the cage face of a shell in loading tray 4 as can best be seen in Fig. 3.
  • Arm 39 further supports a catch member 41.
  • This catch member is pivotally mounted on the arm and arranged to engage with its nose behind the cage flange of a shell as can-best be seen in Fig. 3.
  • a spring 42 also mounted on arm 39 biases catch member 41 toward its position of engagement.
  • the position of the catch member is controlled by means of a guide armor nose 43 pivotal in unison with the catch member and coacting with a guide member 45 and a guide rail 44.
  • guide rail 44 and guide member 45 are engageable with nose 43 thereby lifting catch member 41 out of its engagement with the shell flange during the ramming operation.
  • Guide member 45 is preferably spring actuated by means of a spring 46 to avoid damage tothe coacting components of the catch or retaining arrangement.
  • the next step is to unfold the elevator into the position of Figs. 2 to 4 in which it is ready to receive shells andto tilt the loading table into a position in which the loading surface thereof is disposed to deposit thereon the uppermost shell inthe elevator.

  • the loading table isat an angle to the axis of the loading tray so that the loading table must be tilted into a position parallel to the axis of the loading tray. Thisis accomplished by means of hydraulic power drive 20, the shell being held on the loading table by stop 18.
  • the elevator-ischarged with shells byplacing thesame, one by one, in opening 8 andactuating the elevator rails 9 to 12 until the elevator is filled and the uppermost shell -is deposited upon the loading table.
  • Cylinder 35 is now moved forwardly, by actuating its valve36, into a position close to the breech ring. Furthermore, the loading tray is pivoted by means of its power drive 31 from the position of Fig. 3 into the position of Fig.2 in. which the outer or lower part of the loading tray is in direct alignment with the loading table or more specifically the shell deposited thereon. As a result, spring actuated catch member 41 engages the cage flange of the shell and stop 18 is pivoted into the position released from said flange by engagement with the outer casing wall of loading tray 4 as can be clearly seen in Fig. 2. Thereupon,-valve 36 is 'so actuated that it moves cylinder 35 back into the position of Fig. 3.
