  • the breech end of the barrel is slidably mounted in a jacket composed of parts 2 and 3.
  • Jacket part 3 mounts 2,865,254 Patented Dec. 23, 1958 two ring sectors 4 which are guided in guide tracks 7 on cradle carriers 5 and 6.
  • Ring sectors 4 and guide tracks 7 serve to pivot the gun barrel and its jacket for elevation and depression of the gun, the pivot axis of the barrel being coaxial with the axis of loading tray 13 when the same is in the position shown in Fig. 2.
  • balls, rollers or needles may be fitted between sectors 4 and tracks 7.
  • the top wall of jacket part 3 supports a sleeve 8 through which a shaft 9 is extended.
  • a housing 10 within which a spiral spring 11 is disposed.
  • One end of the spring is secured to shaft 9 and the other to housing 10.
  • the end of shaft 9 within jacket part 3 mounts a jacket sleeve 12 in which the loading tray 13 is fitted which is shown as a cylindrical tube.
  • Tray 13 may either occupy the position of Fig. 1 which is the ramming position of the tray or the position of Fig. 2 which is the loading position of the tray.
  • the tray is slotted at 14.
  • a rammer 15 may enter the tray by means of the slot.
  • Rammer 15 is axially slidable on a'bar 16 one end of which is secured to a bracket 17 extending from the top wall of jacket part 3 and the other to the front wall of jacket part 3.
  • a spring 18 serves to actuate the rammer.
  • the arrangement and the actuation of the rammer are conventional and a detailed description thereof is not essential for the understanding of the invention.
  • Breech ring 19 mounts a camming plate 21 having a cam way 22 coacting with a cam roller 23.
  • Roller 23 is mounted on an arm 24 ending in a shaft 25 pivotally supported in the top wall of jacket part 3.
  • Shaft 25 has secured thereto a curved arm 26 pivotally linked to jacket sleeve 12 and hence to tray 13.
  • Jacket sleeve 12 and tray 13 both have a cut-out 27 so disposed that the cut-out together with a cradle like extension 20 of breech ring 19 forms an ejection path for an ejected cartridge case when the loading tray is in the loading postion of Fig. 2.
  • a shell is shown inserted in the loading tray, the projectile being designated by 28 and the cartridge case by 29.
  • an opening 3a is provided in the appro priate wall of jacket part 3. The diameter of this opening should be at least equal to the inner diameter of loading tray 13.
  • a releasable locking device is provided in order releasably to retain the loading tray in the loading position of Fig. 2 and in alignment with loading opening 311.
  • This locking device is shown in detail in Fig. 3 but for reason of clarity of illustration omitted in Figs. 1 and 2. It is mounted on a bracket 30 extending from tray 13 and comprises a catch 32 pivoted to bracket 30 by a pivot pin 31.
  • Catch 32 extends through a hole 37 in a plate 37a fixedly secured to bracket 30 and is engageable with the respective edge of plate 37a as can be clearly seen in Fig. 3.
  • a spring 33 urges catch 32 into engagement with plate 37a.
  • An arm 34 is on one end pivoted to catch 32 and on the other end linked to a bell crank 35 pivoted at 36 to tray 13. In the catch position of catch 32 the respective arm of hell crank 35 extends into tray 13 and hence the path of a cartridge casing 29 placed in tray 13.
  • 0nd locking device is shown in detail in Fig. 4 but omitted in Figs. 1 and 2 for reason of clarity of illustration.
  • the second locking device comprises a spring housing 38 fixedly secured to tray 13 and slidably housing a plunger ending in a catch 39.
  • a spring 41 urges catch 39 into the position shown in Fig. 4 in which the catch This secabuts against the bottom rim of a cartridge case 29 inserted in the tray thereby preventing an axial rearward movement of the cartridge case out of the tray.
  • a nut 40 serves to retain the plunger and its catch within spring housing 38.
  • the second locking device further comprises a sleeve housing 42 in which a plunger 43, is urged by a spring 44 against one arm of a two-arm lever 45 pivoted to tray 13 by a pivot pin 46.
  • lever arm coacting with plunger 43 is biased into a position in which it engages the forward edge of the base rim of the cartridge case thereby preventing a forward or ramming movement of the latter.
  • the other end of lever 45 coacts with a release bar 47 which should be visualized as being disposed near the ramming device and as coming into engagement with lever 45 when the loading tray is moved into its ramming position as will be more fully explained hereinafter.
  • Engagement of lever 45 with release bar 47 pivots the lever in clockwise direction against the action of spring 44 thereby releasing the cartridge case for the ramming operation.
  • Figs. 1 and 2 finally show an ejection hole 48 through the bottom wall of jacket part 3.
  • This ejection hole leads to a deflector chute 49 and serves to direct a cartridge case 29 leaving cradle like extension 20 away from the gun.
  • the loading tray arrangement as hereinbefore described, operates as follows:
  • the loading tray is now ready for a loading operation.
  • the locking device of Fig. 3 is released by engagement of the respective arm of bell'crank 35 with the cartridge case.
  • catch 39 engages the rearward edge of the rim of the cartridge case and lever 45 the forward edge of this rim thereby securing the shell against axial displacement in either direction.
  • the slanted edge of nose 39 permits passage of the cartridge rim against the action of spring 41.
  • the tensioned spring will return the tray into the ramming position whereby bar 47 comes in contact with lever 45 and pivots the lever out of engagement with the cartridge rirn.
  • the new shell is now ready for ramming and subsequent firing.
  • the cartridge case of a fired shell leaves jacket through cut-out 27, cradle like extension 20, ejection hole 48 and deflector chute 49.
  • an upper deflector may be provided.
  • This deflector is shown in Figs. and 6 in form of an upside down chute 50. It extends laterally from the tray, or more specifically from jacket sleeve 12 and is in alignment with the axis of the barrel and cradle like extension 20 when the loading tray is in the loading position. 7
  • FIGs'. 7 and 8 show a design in which the fixed upper deflector of Figs. and 6 is replaced by a movable upper deflector.
  • an upside-down deflector chute is pivoted by means of pivot pins or a pivot shaft 57 to cars or lugs 56 extending from jacket part 3.
