  • Magnetically actuated coupler assembly
    Patent number: 5823371
    Abstract: A magnetically actuated coupler assembly for model railroad rolling stock is provided. The coupler assembly includes a drawbar having first and second ends. The first end includes an aperture defined therethrough adapted for mounting in a coupler pocket on model railroad rolling stock. The second end includes a coupler head. A coupler knuckle is pivotably mounted to the coupler head by a magnetically actuated pivot post. A first coil spring alignment pin is located on the second end of the drawbar. A second coil spring alignment pin is located on the coupler knuckle. A coil spring is mounted between the coupler head and the coupler knuckle on the first and second coil spring alignment pins for resiliently urging the coupler knuckle to a coupled position.

  • Magnetically-actuated coupler for model railroad cars
    Patent number: 5509546
    Abstract: A magnetically actuated coupling and uncoupling system for model railroads comprised of a drawbar pivotally-mounted to one end of a railroad car, wherein the drawbar contains an integral leaf spring extending from the first end of the coupler to tend to center the drawbar, a coupler body with cantilever springs secured to the second end of the drawbar, a magnetically-actuated post pivotally-secured to the drawbar extending downward from the drawbar, and a pivotally-mounted coupler knuckle secured to the post and pivotally secured to the drawbar such that the pivotally-mounted coupler knuckle will interact with the cantilever spring.
