Definitions
- The-present invention relates to a loading mechanismfor-a gun,-and more particularly to a loadingmechanism for a non-automatic recoiling field gun.
- thep'rincipal objectof the'invention' is to provide a novel loading mechanism which permits rapidramm'ing of a non-automatic recoiling gun without special carefulness on the part of the gun crews
- Another object of the invention is to provide a n'ovel and improved loading mechanism for anon-automatic recoiling gunwhich greatly simplifies and acceleratesdhe loading and ramming operations.
- Still another object of the invention isto plrovidea novel loading tray assembly for a non-automatic recoiling gun.
- a further object of the invention is to provide -a:novel loading tray assembly which precludes an accidental damaging contact between a round and the breech-ring for all practical purposes.
- a still further object of the invention is to provide a novel loading tray assembly in which the tray is locked either in the ramming position or intheloading position, but is automatically unlocked and moved from one position into the other in accordance with theoperationalcycle of the gun operations.
- Fig. 2 is a view similar to Fig. 1, but showingthe tray in its ramming position
- Figs. 3 to are sectional detail views of the breech r-ing and the breech block-of the gun-in three'difierent operational positions.
- a channeled link 6 is pivoted on one endto 2,851,928 Patented Sept. 16, 1958 trunnion bracket'4 pivotal about'a pivot 7L
- An arm 10 is nested in ch'anneled link- 6 pivotal about a transverse pivot 11;
- the free enclof arm 10' isabifurcated and coacts with aspring loaded pin 12 axially.
- displaceable paralleltopivot'8; Pin 12 can be fitted in a suita'ble hol'e inna loadingtray 9 after swinging out arm 10:
- pin 12a Whenpin 12a inserted m its holeglink 6 is rigidly secured to the loadingtray.
- Arr'n lfl ' is n'ormally held by meansof -a locking pin 13 in a position suclr that pin'12 :cannot beinserted in'itshole in theiloading tray.
- a downward movement of link 6 relative to cradle 3 is limited by"an abutment lu'g 14 which is seated on a suitable locking bar a'nd cari -be caused to bear against" the trunnion bracketW:
- One end of a second link 17 islpivotal. about a pin 16*which 1's mountedJonFa bracket15secured tocra'clle'3.
- the other end of link-17 is: pivotal about a"pivot 18 eXtendin'g from: loadingtray 9.
- links6 and 17, loading tray 9 and the distance.between pivotsfi'and 16' define atparallelogram, the-components6, 17" and 9 of'which' are relatively movable.
- The-linkagesystem formed by links ?
- the loaidn'g tray is compelled tomove parallelto'the axisof thebarrel and perpendicul'a'rly thereto;
- the loading tray will always oceupy a positiohparallel-to' theaxisof the barrel or more specifically, the bor'e o-f the-ba'rr'el and the loadin'g cha'rnber therein.
- the spring 27 is compressed as the tray is lowered to the position shown'in Fig. Z-andassists in' raising the tray to the position shown in Fig. 1 after the round has been loaded into the' breech block in the manner'hereinafter described.
- Bracket 15' has' a hole in which is fitted a spring loaded pin" 28 coa'cting with one. end of a catch 29 so thatitibiases upwardly said end of the catch.
- the catch is "pivotal about a pin 30 fitted in a bearing member 31 securedto' trunnion bracket'4.
- Pin 30 extends through bracket 4 and"the end of thepin protruding from the bracket onthe side of breech ring 2' seats ant arm 32 ending in a lug 33.
- This'lug coactswith adog 34 on: breech ring 2: Catch 29 further coacts with. a nose 35' extendingfrom link 17.
- a second catch means 38 is pivotal about a'pivot 36 mounted on a bracket 37 fastened to the breech ring; Catch 38has a hookon'one end and the "other endofthe catch is extended to coact with a second release mean'sin.
- breech block 42 which is shown as being movable transversely ofthe' axis of: barrel 1.
- the breech block is opened by'the recoil movement of the gun for ramming:
- pin 39 When the breech block is in the position of Fig. 3 pin 39 is biased by spring 40 into the position in which catch 38 occupies its outwardly tilted position. The pin 39 remains in this position as long as it moves within the straight portion of the groove. However, when the breech block moves into the position of Fig. 5, either from its open position or its closed position, the inner protruding endv of pin 39 engages a ridge or rib 43 on the breech block which axially displaces catch 38 into a position in which the catch is withdrawn toward the Wall of the breech ring; When the breech block reaches the position of-Fig. 4 in which ridge 43 has passed pin 39, catch 38 is returned into the position of Figs. 3 or 4 by the action of spring 40. In other words, catch 38 remains stationarily in the position of Figs. 3 and 4 unless its operating pin' 39 is in engagement with ridge 43. As can be seen in Figs. 4 and 5 the catch is positively guided by pin 39.
- Catch 38 coacts with a locking member 44 secured to link 17 and extending transversely on both sides thereof.
- the upper part of member 44 has a bevelled edge which is engageable by the hook of catch 38 and the lower protruding part of member 44 has a shape such that it can abut against the top side of the hook of catch 38as will be more fully explained hereinafter.
- Link 17 has secured thereto a second locking member 45 which extends transversely of link 17 generally parallel with catch member 44.
- Member 45 coacts with abar 46 which is axially displaceable in a transverse hole formed in the respective wall of breech ring 2.
- the inner end of bar 46 should be visualized as coacting with the conventional firing mechanism of the gun.
- Member 45 overlies bar 46 in all positions of link 17 except the position shown in Fig. 1. As a result, bar 46 is pressed back into the breech ring.
- the firing mechanism should be visualized as being locked in the pressed-in positionof bar 46 by means suitable and well known for the purpose. Accordingly, bar 46 constitutes a control member for the firing mechanism.
- a round or shell 47 is shown in Fig. ,2 as being placed upon loading tray 9.
- the breech block 42 is opened. During the movement of the breech .block from its closed position into its open position catch:
- the hook of catch 38 engages the bevelled: edge of catch member 44 thereby retaining the loading tray in its lower or ramming position as isshown in Fig. 2.
- the new round can now be rammed, either by means, of a rammer or by hand. Due to the correct location of the round in relation to the 'loading chamber and th breech ring, the gun crew is relieved of the necessity of being specially careful to avoid an accidental damaging contact between the round and the breech ring. After the round has been rammed, the breech block is closed. During the closing movement, catch38 is again temporarily tilted inwardly by the engagement of pin 39" withridge 43. As a result, catch 38 is disengaged-fro locking member 44.
