Definitions

  • the present invention relates to'installations of automatic guns, and more particularly to automatic guns equipped with aloading pendulum for feeding around of ammunition from a source of supply such as a hoist to'the ramming position.
  • the loading pendulum can swing freely between a position fixed in relation to a stationary part of the gun (supply position) and a position fixed in relation to the elevating mass of the gun (ramming position).
  • Aspecific object of the invention is to provide a novel and improved gun installation of the general kind above referred to, in which the amplitude of the swinging movements of the pendulum is continuouslyand automatically controlled in accordance with the elevational position of the elevating mass of the gun (gun barrel) so as to reduce said amplitude proportional to, an increasing elevation of [the gunbarreL.
  • a loading pendulum assembly according to the invention maybe advantageously used for a single pendulum installation and also for synchronization of two alternately operating pendulums.
  • FIG. 1 is a diagrammatic view of a gun installation ac- 1 cording to the invention showing the loading pendulum in its loading position.
  • FIG. 2 is a view similar to that of FIG. 1, but showing the loading pendulum in its ramming position.
  • FIG. 3 is a viewsimilar tothat of FIG. 1, but showing the gun barrel elevated from the horizontal position of FIG. 1.
  • FIG. 4 is a view similar to that of FIG. 2, but showing the gun barrel in elevated opsition. Y I
  • FIG. 5 is a perspective view of structure of a loading pendulum assembly based upon the principle diagrammatically shown in FIGS. 1 through 4, as usuable in prac tice and V i --FIG. 6 is adiagrammatic view of a modification of the pendulum assembly according to FIGS. 1 through 4.
  • FIGS. 1 through 6 only those parts of the gun and its mount are indicated that are essential for the understanding of the invention.
  • FIGS. 1 through 4 show part of the elevating mass lofthe gun and more specifically the recoil jacket and a-portion of the barrel of the gun.
  • the nonrelevating part of the gun mount is shown at 2.
  • the recoil jacket 1 is pivotally sup ported on a trunnion 3, the mounting for which is not shown.
  • the supply of ammunition is indicated at 4 and may be visualizedat the top end of a hoist.
  • T heloading pendulum assembly comprises a lever or a for instance on trunnion 3 for pivotal movement in unison with the recoil jacket.
  • the other end of link 5 is pivotally connected to one end of a guide link 6, which is formed with a lengthwise guide groove 8 and mounts at its, other end a roller 7.
  • Roller 7 is guided in a circularly curved guide track 9' formed in a guide link or member 9, fixedly secured at one end to the nonelevating part 2 of the gun.
  • a loading pendulum 10 is pivotally mounted on the elevating mass. 1 of the gun,
  • the pendulum is extended by a link or'lever.11 pivotal in unison with the pendulum.
  • Link 11 is pivoted to one end of a driving bar or link 12.
  • the other endof driving link 12 ' mounts a roller. 14 which is guided in a second curved guide track 15 formed in a guide member or link 15 and having the same curvature as guidetrack 9'.
  • Roller 14 also engages guide track 8 of link 6 and is lengthwise slidable in that guide track.
  • Guide member 15 is pivotal about a-pivot pin 16 on the non-elevating part 2 of the gun. The respective ends of guide members 9 and 15 are shown tobe in registry in FIGS. 2 and 4.
  • guide member 15 is pivoted tola drive bar 17 which in turn is hi'ngedto a reciprocatory-lever 18 which should be visualized as being driven by suitable power drive means (not shown).
  • Lever v 18 is driven by the drive-means from the position shown
  • a buffer 13 is interposed in link 12 and serves to absorb joints occurring between-roller 14 and driving guide member 15 and also to compensate for possible backlash in the transmission formed by the aforedescribed links and guide members.
  • curved member 15 will be turned in clockwise direction taking along with it driving link 12 which is drivingly coupled by lever 11 to pendulum 10 whereby the latter is turned in counter-clockwise direction into the position of FIG. 2.
  • Lever 5 will remain in its position, butroller 14' of link 12 will slide along guide track 8 towards the'outer end thereof. The roller will also slide in guide track 15' toward the free end of said track.
  • the ratio of transmission is selected in the exemplification according to FIGS. 2 and '4 so that guide members 9 and 15, links 6 and'12 and levers 5' and 11 are in registry when pendulum is in its ramming position.
  • pendulum 10 in FIGS. l and 2 must turn through an angleof 90 to reach the ramming position which is the widest angle through which the pendulum must Swing in the said position of elevating mass. Accordingly, the displacements relative one to another which the links and members of the linkage assembly must perform are also the greatest possible displacements; Y
  • lever 18 is driven in counterclockwise direction, that is, from the position ofFIG. 2 into the position of FIG. 1.
  • Such movement of the lever compels corresponding movements of all the links and members drivingly coupled therewith as is evident from the previous description. 7
  • Driving lever 18 has been described as a reciprocatory lever, but it is also possible to rotate the lever.
  • drive means for the bar 17 can be an arbitrary one provided it can give the guide member the desired movement between the two positions shown in FIGS. 1 and 2.
  • the gun may be elevated from the horizontal position of FIG. 2 into the elevated position of FIG. 4 and vice versa without moving the loading pendulum out of its ramming position.
  • guide tracks 9 and 15' are in registry at the beginning of the elevational movement of recoil jacket 1.
  • Link 6 will be lifted when and while the recoil jacket 1 is elevated, but a at the same time it takes along driving link 12 through the same distance due to the coupling between roller 14 of driving link. 12 and link 6.
  • the lifting movement of link 12 has no effect upon the position of pendulum 10.
  • pendulum'10 will. move through the required smaller arc in response to turning of lever 18 ramming position of FIG. 4 into the loading position of FIG 3 when lever 13is returned from the position of FIG. 4 into the position of FIG. 3.
  • the ratio of transmission which is transmitted from lever 18 to V the loading pendulum is'continuously controlled in accordance with the elevational position of the gun.
  • the link 6 need not have the-form of a bar but can
  • the track 8 in FIGS. l 4 is shown straight, but it can have a curved form and a direction which more or less corresponds to the one shown in FIG. 5.
  • FIG. 5 The structure of the loading pendulum assembly of FIG. 5 is evident from the previous description by referring to the corresponding reference numerals. The only diiference is that the mountings for guide members 9 and 15 are shown separate as this has been found to be more practical from a manufacturing viewpoint. It may also be noted that in FIG. 5 the guide tracks 9 and 15 are shown double, links 6 and 12 are bifurcated and each mounts two rollers 7 and 14 respectively.
  • the guide member 9 of the proceeding figures is replaced by a link 19 which is pivoted at one end to the non-elevated part of the gun mount at 20.
  • the other end of link 19 is formed with a guidetrack 21 in which roller 14 of link 12 is guided lengthwise slidable.
