  • Patent number: 8616112
    Abstract: A drive for a weapon is provided, wherein rotational motion of a motor is converted to a forward or reverse motion of the breech in a simple manner using the Scotch yoke principle. In order to allow rest periods of the breech in the end positions, the crank radius is defined by a control cam, which changes when the crank is rotated. The hinge pin of the crank may be externally driven via a pinion shaft. A yoke pin is arranged in a groove of the crank so as to be radially displaceable and carries the breech carrier or the breech in a groove extending transversely to the direction of fire via a sliding block. Two rollers are arranged on the crank pin and run in control cams in the weapon or crank housing. The control cam is subdivided into different sectors/sections, thereby achieving the desired motion of the breech.

  • Patent number: 6591733
    Abstract: The present invention relates to a method and a device for handling artillery shells (14-16) when loading artillery guns (1) that have an integral shell magazine (9) fixed in the traverse system but independent from the elevating mass, which magazine on command feeds out shells (14-16) one by one with a specific linear velocity in the longitudinal axis of each shell. Each shell is subsequently transferred to the loading position for the gun by a loading pendulum (13) and cradle (6). The basic idea behind the present invention is that the outfeed velocity of the shells (14-16) from the magazine (9) shall be braked to zero in a brake module (12) mounted on the gun while they lie in a shell carrier (17, 18) mounted on the loading pendulum (13).

  • Patent number: 6460448
    Abstract: The loader assist for mortars allows for the automated loading of ammunition through the muzzle. The invention assists soldiers by transporting the shell into the muzzle from a lower position near the base of the mortar tube thus reducing exposure to enfilade enemy fire and the effects of muzzle blast. The loader assist comprises a frame surrounding the mortar and attached thereto. The frame is supported on pivots mounted to a turntable such that both the invention and mortar move as a unit. A lift device is positioned at the center of the frame and parallel to the mortar axis. A carriage comprising a transfer device is positioned on top of said frame. Said elevator is comprised of two linear actuators which are positioned opposite each other, allowing the jaws on each shuttle to act in pairs with the respective jaws on the other, to grip the shell in two places.

  • Patent number: 6443045
    Abstract: A rammer for an artillery piece with a barrel that can be elevated. The rammer has a cradle upstream of the barrel. The cradle is aligned with the powder chamber, has an accommodation for the shell, travels subject to a guide along a track that parallels the axis of the barrel, is coupled to a piston-and-cylinder mechanism that accelerates it toward the barrel, and is provided with a brake. The piston-and-cylinder mechanism is controlled by pneumatic controls that accommodate a rapid-opening valve. The valve diverts air back and forth between a source of compressed air and a vent. There is a pressure-reduction component with an electrically controlled proportional pressure-regulation valve between the source of compressed air and the rapid-opening valve. Signals from a fire direction system or position generator are forwarded to the electric controls. The pressure-regulation valve is then activated, reducing the ramming pressure in accordance with a prescribed formula as elevation decreases.
