  • Patent number: 9026281
    Abstract: A device for monitoring the status of a railcar handbrake having a hand operated handle, which device has a load bearing member configured to be inserted in the linkage of a railcar handbrake system so that the force applied to the brake system passes through the load bearing member. A strain gauge mounted on the load bearing member measures the strain. The information from the strain gauge is indicative of the force applied by the handbrake to the brake and is used to determine the status of the handbrake. Means for determining motion of the railcar is also provided. In one form, if it is determined that the brake is on and the railcar is in motion, information, such as an alarm, is transmitted. A system and method of monitoring a railcar handbrake are also provided.

  • Patent number: 8910808
    Abstract: An improved coupler-knuckle assembly is comprised of a coupler body, a knuckle, and at least two knuckle retainer plugs. The knuckle has an internal coring geometry that increases the cross-sectional area of the throat portion of the knuckle compared to previous designs. The present invention's knuckle design includes a top and a bottom tapered holes in the knuckle with a locking groove at the bottom of each tapered hole for the knuckle retainer plugs to snap into. The knuckle retainer plugs are inserted through the coupler body and into the tapered holes in the knuckle. The improved coupler-knuckle assembly of the present invention reduces fatigue on the coupler, knuckle, and knuckle pin, prevents misalignment of the coupler-knuckle assembly, and prevents knuckle pin breakage.
