the two torsion bar springs transversely to the axis of the soul in the cam tracks 8 are non-positively connected. While Tube sheets arranged side by side and at their lifting of the closure piece during the advance of the opposite ends are clamped, the gun barrel being the torsion bar springs 13 and 14 each at the free ends attached lever in tensioned, so that the Schheßvorgang that in itself arranged below the bottom locking piece 5 automatically by the weight of the locking piece Groove strips are performed. takes place through the tensioned torsion bar springs under-Further Details of the invention will emerge based.

The guide flanges 7 fixed by the launch of the projectile 12 at the cradle 3 counteracted the recoil lifts the tube 1 together with the bottom over the forged tube sheet 4, and the end piece 5 shoots backwards, with the guide and thus the Shutter open. The guide rollers 6 with the lifting of the switch Sd along the flanges 7 carry cam tracks 8 which are moved on the guide track 9 until they come to a stop with a straight line 8 α on the end opposite the firing direction. Before the short fire running parallel to the upper edge of the cradle, a new floor straight line 8 a started at the loading machine 11, then fed into an ascending 40 12. Without interruption, curve Sb is passed over, to finally end in a curve 8c that is steeply sloping through the tensioned pipe hauler. In addition to this cure advance of the pipe 1 with the bottom closure piece 5, venbahnen 8, the guide flanges 7 still carry the straight guide grooves 9, which is caused by the entrainment of the loading machine 11, through a sensible construction. At the inside of the guide flanges 7 are 45 of this flow, which serve with the taking of the highest and when the gun barrel returns to the point of the rising curve Sb through the control of the guide rollers 6. The lower edge of the roller 6 comes to a preliminary end, once the full opening of the bottom lock S, which runs parallel to the upper edge of the cradle, is reached again, the groove 9 flows continuously into the short straight line 8 α . that the attachment of a new projectile 12 and the Since the curved path 8 and the guide groove 9 50 insertion of a new cartridge load can take place, it is provided that the rising curve 8 b of course can instead of the separate also in the area of the guide groove 9 as a switch Sd cartridged ammunition can be used.

1 2 patent claims made demands regarding performance increase 'in terms of range and rate of fire 1. Gun with one opposite the barrel conditional among other things a reinforcement of both the cradle the returning gun barrel and a bottom piece of the gun barrel as well as the verquer to its soul axis displaceable locks 5 locks. However, this has the disadvantage of larger closure, its opening movement results in forward measurements and thus higher weights, Derived from a guideway via a roller, thereby realizing the further requirement, is, that when the gun barrel returns, namely an increased rate of fire, in beausser The intervention remains, which makes it more difficult. draws that the tube sheet (4) around- io the object of the invention is therefore opposite gripping.

Gun according to claim 3 and 4, characterized in an advantageous embodiment of the invention characterized in that the levers (15, 16) are in the lower part of the switch with a joint on the guideway half of the bottom plug (5) arranged attached and the return pipe through the in the Groove strips (17, 18) are performed. 45 guide groove, retractable guide pulley can be lifted. In itself there would also be a switch in the form of bar, in which the guide groove is one to the rear decreasing depth and the guide rollers The invention relates to a gun which can be lowered. However, this would mean a weakening of the lock that is reversing compared to the cradle and a protective tube and a cross to its core axis that would be more expensive and more susceptible to failure.
Slidable shutter, the opening movement of which The closing of the shutter according to the invention when advancing from a guideway via a generally takes place by its own weight is derived from the roller, which is diverted when the forward movement and loading process are reversed, with the Leitschützrohres remaining disengaged. 55 roll onto one of the ascending curved tracks. In a known gun of this type is performed on closing, steeply sloping curved path the returning gun barrel with a cure. The closing process can, however, continue Venbahn provided crank piece stored, which in the advantageous embodiment of the invention Advance speed can be accelerated by a fixed cradle that the bottom locking piece arranged roller is actuated and the opening movement 60 by lever acting on its underside, the causes the closure. As a result of the free ends, one lever action each clamped in the tube sheet occurs comparatively large forces on the torsion bar spring are attached to the tube sheet due to the structure of the lock and the control or with the cam tracks non-positively connected members are not reducible. This is why. The use of torsion bar springs for closing Both the known proposal and other 65 ßen of gun breeches are known per se. Closures of this type are not readily available again. A particularly advantageous because they are space-saving Temporal, performance-enhanced guns transferable. Formation of the lock is in further training The more recently namely on such guns design of the invention is also achieved in that
