20 FIG. 7
ROBERTLZ INVEN ATTORNEY LOADING DEVICE FOR GUNS This invention relates to semi-automatic loaders for artillery pieces and particularly to loaders for guns mounted in tanks or other armored vehicles where space is limited and rapid loading is desirable.
Because of the configuration of various types of armored vehicles, it is difficult and impractical for a handler to lift and insert a relatively heavy shell in the breech of the gun carried by the vehicle. It becomes necessary, therefore, to provide mechanical means, accessible to the handler, upon which the shell can be placed, and which will lift and insert and shell into the breech of the gun to load it for firing.
It is the object of this invention therefore, to provide a new and improved loader for rapid firing guns which is simple, efficient, and rapid in operation.
The unique configuration contemplated by this invention utilizes a sliding loading tray which is arranged in conjunction with a single hydraulic cylinder for lifting the shell, inserting it in the breech of the gun, and returning it to the loading position. As will be hereinafter more fully described, this is accomplished by mounting the loading tray on a swinging arm upon which the tray is allowed to slide. A member adapted to be extended or retracted by a conventional hydraulic cylinder is pivoted at one end to the gun structure and at the other end to the tray. After a round has been placed in the tray, the member is extended to swing the arm and tray into loading position at the breech of the gun. A latching arrangement locks the arm in position so that subsequent retraction of the member is effective to slide the tray toward the breech to insert the round into the gun. Reextension of the member then slides the tray to the end of the arm, at which point the tray is latched in place on the arm and the arm is simultaneously unlatched, so that retraction of the member returns the arm to loading position.

FIG. 9 is a cross sectional view taken along line 9-9 of FIG. 5.
FIG. 10 is a cross-sectional view taken along line 10-10 of FIG. 5.
The loading device of the present invention is shown in the drawings in conjunction with a conventional gun I fixedly carried by a gun cradle 2. The cradle shown is for convenience in illustration only and is not essential to operation of the loading device, any convenient type of gun mounting being suitable for use with the device herein described.
The gun I is provided with a pair of journals 4 fixed to opposite sides of the gun and which serve as pivots for swinging arm 6. Arm 6 is composed of a yoke portion 7 and a rearwardly extending slide tube 8. Each arm of yoke portion 7 terminates in a bearing 9 carried on one of the journals 4 so that arm 6 may swing about the journals. Slide tube 8 carries a pair of slides 10 affixed one to each side of the tube as shown in FIGS. 8 and 10. A shell carriage 11 is slidably carried on slide tube 8 by means of slots or ways 12 which engage the slides 10, as best shown in FIG. 8, so that carriage 11 is adapted for reciprocating motion along slide tube 8. A conventional hydraulic cylinder 13 of the type having an internal piston contained within the cylinder for reciprocating motion therein in response to hydraulic pressures introduced into the cylinder by means of hydraulic lines 14 and 15 is connected to bracket 16 extending from the underside of the gun breech 5, by means of pivot pin 17. Piston rod 18 is attached to the internal piston and may be extended or retracted within cylinder 13 by suitably controlling the hydraulic pressure. Rod 18 is attached, by means of pivot pin 20, to bracket 19, which is carried by the underside of carriage 11. A latching mechanism 21, the function of which will be more fully described hereinafter, is affixed to the rearward end of slide tube 8.
Referring to FIG. 5, it may be seen that the latching mechanism 21 comprises a latch arm 22 pivoted by means of pin 47 in a bifurcated bracket 23 which is fixed to the end of slide tube 8. A detent lug 37 fixed to cradle 2 is adapted to be engaged by latch arm 22 to retain swinging arm 6 in the upper position shown in FIG. 2. A striker arm 24 having a longitudinal slot 25 formed therein is also carried by pivot pin 47, the slot 25 allowing vertical motion of striker arm 24 with re spect to bracket 23. A lug 26 extends from the side of striker arm 24 and engages the lower portion of latch arm 22 upon counter-clockwise rotation of arm 24 as viewed in FIG. 6. Torsion spring 27, which is carried by pin 28 in bracket 23, exerts a force against the lower end of latch arm 22 tending to rotate the arm 22 in a clockwise direction against lug 26. A tension spring 29, as shown in FIG. 9, is connected between bracket 23 and lug 30 on the striker arm 24 and serves to urge the arm 24 to the upper limit of the travel allowed by slot 25. A swinging bifurcated yoke 31 is pivoted to bracket 19 by pin 33. Torsion spring 45, also carried by pin 33, acts against pin 46 carried by the yoke 31 to urge the yoke in a counter-clockwise direction. A latch bar 34 having a sloping upper surface 35 extends between the arms of yoke 31. Detent lug 36 is fixed to the end of slide tube 8 and is adapted to engage latch bar 34 as will be hereinafter described, to prevent motion of carriage 11 toward gun breech 5.
Beginning at the position depicted in FIG. 1, the complete loading cycle may now be described. A round of ammunition 38 is placed in position with its rear end in the carriage 11, the forward end of the round being supported by tray 30 which is affixed to the upper side of slide tube 8. To initiate the loading cycle, hydraulic cylinder 13 is actuated to extend piston rod 18, thereby swinging arm 6 about journal 4 upward into the ram position shown in FIG. 2 and bringing round 38 into alignment with the chamber of the gun I. As arm 6 swings into alignment with the chamber, the upper end of striker arm 24 engages stop 42 which is fixed to the side of detent lug 37, so that striker arm 24 is forced downwardly against the action of spring 29 to the limit of the travel allowed by slot 25. A cross bar 43 carried by the lower end of striker arm 24 engages the yoke 31 upon downward motion of striker arm 24, swinging the yoke downward to disengage latch bar 34 from detent lug 36. Simultaneously, latch arm 22 slides past detent lug 37, being deflected against the action of spring 27 by the lug and then snapping back into latch position as shown in FIG. 5. At the same time hydraulic cylinder 13 begins its return stroke, retracting piston rod 18. Since arm 6 is now latched in its upper position and yoke 31 has been disengaged from detent lug 36, retraction of piston rod 18 is effective to slide carriage 11 forward along slide rod 8, carrying round 38 forward into the gun chamber. Retraction of the piston rod 18 is terminated at the position shown in FIG. 3, the inertia of round 38 being sufficient to carry it the remaining distance into the chamber of gun 1. At this point hydraulic cylinder 13 again extends piston rod 18, moving carriage 11 back along the slide rod 8. As the carriage approaches the rearmost position, yoke 31 engages cross-bar 43, swinging striker arm 24 counterclockwise to the position shown in FIG. 6. Lug 26, which is abutting the lower end of latch arm 22, rotates the latch arm to disengage it from detent lug 37. At the same time the upper end 41 of striker arm 24 is disengaged from the lower surface of detent lug 37 and is slid upward by action of spring 29 against the underside of stop 42. Simultaneously with the above related action, the sloping surface 35 of latch bar 34 strikes detent lug 36, deflecting the yoke 31 downward against the action of spring 45 to allow latch bar 34 to pass the detent lug 36 and be snapped into latched position behind the lug by the action of spring 45 when carriage 11 reaches its rearmost position.
Retraction of piston rod 18 begins again at this point, and since the carriage 11 is now latched against forward motion on slide bar 8 and latch arm 22 is unlatched from detent lug 37, as shown in FIG. 6, retraction of the rod 18 is effective to swing arm 6 downward toward the load position. As arm 6 begins its downward motion, striker arm 24 is maintained in position against the underside of stop 42, by action of spring 29, and slides with respect to latch arm 22 until yoke 31 releases the cross bar 43. FIG. 6 shows the position of the latch elements just before yoke 31 has released the cross bar 43. As arm 6 continues to swing downward, striker arm 24 is held against the underside of stop 42 until pivot pin 47 reaches the lower end of slot 25, striker arm 24 then moving downward so that its upper end, which has, until this point, been constrained from movement by the sloping face 46 of detent 37, is free, thus allowing striker arm 24 and latch arm 22 to be rotated about pivot pin 47 by action of spring 27 to the position shown in FIG. 4. When piston rod 18 is fully retracted, arm 6 will have again assumed the loading position so that the cycle may be repeated.
Because of the positive action of the latching arrangement and the relative simplicity of the loading device, the loading action is extremely rapid, so that the rate of fire is limited only by the rapidity with which the handler can lift a round of ammunition from a rack and place it in the loading tray.
This unique design of a loading device provides a simple, rugged and efficient arrangement for lifting a round of ammunition to the breech of a gun, and ramming the round with the use of but a single hydraulic cylinder.
while but one embodiment of the present invention has been shown and described, it is to be understood that many changes and modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
