An automatic weapons fed by a cartridge belt comprising a trigger and a feed mechanism for feeding the cartridge belt by applying traction force to the belt to advance the belt from a casing in which the belt is placed in overlapping folds. A feed assisting mechanism is provided for applying additional traction to the belt and comprises a star-shaped rotor in mesh with the cartridge belt in a zone situated downstream of the feed mechanism and an electrical motor drivingly coupled to the rotor and coupled to the trigger to furnish a torque whose energization is controlled by the operation of the trigger so that each time the trigger is activated the motor is energized. The feed assisting mechanism is disposed on a guide passage for the cartridge belt disposed between the feed mechanism on the weapon and the casing for the belt.
In an automatic weapon fed by a cartridge belt and comprising a trigger and feed means for feeding the cartridge belt by applying traction force to the belt, an improvement comprising feed assisting means for applying additional traction to the belt comprising at least one star-shaped rotor in mesh with the cartridge belt in a zone situated downstream of the feed means and an electrical motor directly drivingly coupled to said rotor and coupled to said trigger to furnish a torque whose energization is controlled by the operation of the trigger such that each time the trigger is activated the motor is energized, said motor being a direct current motor having a laminated coil and planar air gap and including an output shaft directly coupled to said rotor in driving engagement, said motor being underfed in voltage and being capable of periodic stoppage during stoppage of the belt while continuing to deliver torque to said rotor without overheating the motor.
In an automatic weapon fed by a cartridge belt and comprising a trigger and feed means for feeding the cartridge belt by applying traction force to the belt, an improvement comprising feed assisting means for applying additional traction to the belt comprising at least one star-shaped rotor in mesh with the cartridge belt in a zone situated downstream of the feed means, an electrical motor drivingly coupled to said rotor and coupled to said trigger to furnish a torque whose energization is controlled by the operation of the trigger such that each time the trigger is activated the motor is energized and timing means coupled to said motor to deenergize the same at the end of a selected time interval at least equal to the normal time of continuous usage of the weapon.
In an automatic weapon fed by a cartridge belt and comprising a trigger and feed means for periodically feeding the cartridge belt by applying traction force to the belt, a method comprising applying additional traction to the cartridge belt by meshing at least one star-shaped rotor with the cartridge belt in a zone situated downstream of the feed means and driving the rotor by an electrical motor directly drivingly coupled to said rotor and coupled to said trigger to furnish a torque whose energization is controlled by the operation of the trigger such that each time the trigger is activated the motor is energized, constructing the motor as a direct current motor having a laminated coil and planar air gap and an output shaft directly coupled to the rotor, and underfeeding the motor in voltage to permit periodic stoppage thereof during stoppage of the belt, while continuing to deliver torque to said rotor without overheating the motor.
