  • Patent number: 10011289
    Abstract: A locking mechanism for a brake cylinder that has a tube surrounding the hollow shaft of the brake cylinder with a first set of teeth formed along an outer surface thereof. A gate having a second set of teeth corresponding to the first set of teeth is moveable in between a first position, wherein the first and second set of teeth are engaged to prevent movement of the brake cylinder piston, and a second position where the first and second set of teeth are disengaged to allow movement of the brake cylinder piston. A spring biases the gate into the locked position and a supplemental piston responsive to a source of brake pipe pressure can move the gate into the unlocked position so that the main piston is free to move.

  • Patent number: 8511760
    Abstract: A roller element bearing 40 track bushing system embodiment for track link assemblies 14 capable of being used on a vehicle 10 having an endless track 12. Each track link assembly 14 has a track shoe assembly 20 defining a front pin bore 22 and a rear pin bore 24. Each track link assembly 14 has a front pin 26 at least partially disposed within the front pin bore 22, and a rear pin 28 at least partially disposed within the rear pin bore 24. The embodiment discloses at least one roller element bearing 40 disposed within the front pin bore 22 around a portion of the front pin 26, at least one roller element bearing 40 disposed within the rear pin bore 22 around a portion of the rear pin 28. The roller element bearings 40 cooperate to prolong the useful life of the track link assembly 14.
