Abstract
A transfer device for pushing a projectile (3) into the barrel of a weapon in the direction of the barrel (1) of the weapon along a transfer trough (2). The transfer device has two turning wheels (5, 6), a flexible power transmission element (7) forming a closed loop, and two transfer elements (8, 10) mounted to push the projectile (3) in consecutive steps towards the barrel (1) of the weapon.
Claims8
A transfer device for pushing a projectile into the barrel of a weapon along a transfer trough (2) that is located behind the barrel at least during the transfer and positioned substantially parallel to the barrel, the transfer device having two turning wheels (5, 6) at a distance from each other and an elongate power transmission element (7) that is a flexible element forming a closed loop and mounted to run around the turning wheels (5, 6) and that during the transfer of the projectile moves at least along part of its length substantially parallel to the transfer trough (2) toward the barrel of the weapon, and at least two transfer elements (8, 10) that under the influence of the moving power transmission element (7) push the projectile (3) from behind in consecutive steps toward the barrel of the weapon, whereby the first transfer element (8) is always in a position, in which it extends behind the projectile (3) and moves the projectile (3) first a part of the way, while the second transfer element (10) is in a position in which it is at the side of the projectile (3) and disengaged from the power transmission element (7), and when the first transfer element (8) is in a predefined position, the second transfer element (10) engages the power transmission element (7) and turns behind the projectile (3) to push it, characterised in that the power transmission element moves in one direction during the transfer of the projectile, that the power transmission element (7) has two connection elements (9, 11) at a distance from each other, and the first connection element (9) is engaged to move the first transfer element (8), and after the first transfer element (8) has moved the projectile (3) a part of the way, the second connection element (11) engages to move the second transfer element (10) at the same speed in the same direction, that the second transfer element (10) starts to push the projectile (3) from behind before the first transfer element (8) stops moving the projectile (3), that, after this, the movement speed of the of the first transfer element (8) decelerates and the second transfer element (10) continues to push the projectile (3) into the barrel of the weapon as the pushing movement of the first transfer element (8) ends.
