  • Brake
    Patent number: 9915307
    Abstract: A brake for machine and method of using the brake is disclosed. The brake may comprise first and second brake linings configured to be frictionally engageable with a rail, a first biasing member configured to urge the first brake lining to engage the rail, and a first actuator configured to move the first brake lining (38) to disengage the rail when the first actuator is energized. The brake may be configured to be mounted on a machine, floor or the like.
    Type: Grant

  • Non-linear stiffness roller assembly
    Patent number: 9630805
    Abstract: A roller apparatus is provided. The roller apparatus may include a bearing wheel configured to rotatably couple the roller apparatus to a roller shaft, and a resilient member radially disposed about the bearing wheel and configured to contact a guiderail at different magnitudes of loads. The resilient member may include a first section of a first diameter and a second section of a second diameter. The first section may be caused to deflect in response to loads within a first load range, while the second section may be caused to deflect in response to loads within a second load range. The resilient member may exhibit a stepwise increase in stiffness with a gradual increase in load.
