Resiliently supported magnetic rail-brake suspension device

A device for suspending a rail-brake magnet from a structure on a railway vehicle at a predetermined distance above a rail when in its de-energized state, said structure having a vertical opening therein, and comprising a compression spring and having a lower end surrounding said opening and an upper end, a plate on the upper end of said spring, means for connecting said spring to a rail-brake magnet and comprising a rod having an upper end connected to said plate and passing within said spring through said opening and having a lower end, a bearing block on the lower end of said connecting rod having a spherical bearing surface on the top thereof and engaging the underside of the rail brake magnet to pivotally support the rail brake magnet, and abutment means for limiting the movement of said spring in the direction of raising said rail-brake magnet to its de-energized position such that said spring is subjected to an initial stress when the rail-brake magnet is raised to its de-energized position, and an adjustable threaded coupling between said rod and one of said plate and said bearing block.
