  • Patent number: 4295369
    Abstract: A gear meter is characterized by a dual magnetic drive used for driving meter accessories. The measuring gears within the gear meter are provided with driver magnets which urge the rotation of driven magnets mounted on rotatable shafts arranged within the fixed shafts about which the measuring gears rotate. The rotating shafts are coupled with gears which either correspond in shape and size to, and which are radially aligned with, the respective measuring gears, or are circular. The coupling gears combine the torque generated through the two rotating shafts to drive a meter accessory shaft.
