Patent number: 8534180Abstract: A weapon system includes a carrier vehicle and a vehicle dependent mortar, wherein the carrier vehicle has a crew space and a weaponry space to house the mortar, and the mortar is charged in an index position with mortar grenades, with several sheddable propellant modules on the tail shaft thereof. The weapon system avoids manual loading of the mortar with mortar grenades because an automatic loader is arranged in a weapon space separated from the crew space by a separating wall. The loader transports the mortar grenade from a magazine in the weapon space into the index position of the barrel of the mortar and axially inserts it into the mouth of the barrel, and an automatic shedding device is arranged in the weapon space to automatically remove unnecessary propellant modules from the mortar grenade after fixing target parameters and before insertion of the mortar grenade into the barrel.Type: GrantFiled: April 18, 2011Date of Patent: September 17, 2013Assignee: Rheinmetall Landsysteme GmbHInventors: Wilfried Becker, Wolfgang Boer, Hans-Ulrich Desgranges, Hans Moser

Patent number: 6460448Abstract: 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.Type: GrantFiled: August 17, 2000Date of Patent: October 8, 2002Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Roy A.
