Abstract: A brake shoe assembly with a removable brake shoe pad. A brake shoe assembly includes a brake shoe plate. A brake shoe pad and a pair of connector plates are provided. The brake shoe pad is adjustably received on the bottom of the brake shoe plate. The connector plates are slidably positioned onto the top of the brake shoe plate, and are connected to the brake shoe pad through the brake shoe plate by rivets through corresponding openings formed therein. The connector plates are additionally connected to the brake shoe plate by vertical members, with screws inserted through corresponding openings formed therein.

Abstract: A magnetically cushioned support structure for a mattress or seat includes a pair of spaced-apart, aligned sheets of non-magnetic material, each sheet having magnets disposed on its inner face in opposition to magnets on the other sheet, with the opposing magnet faces in each magnet pair having like polarity. The two magnet-supporting sheets are secured to one another by blocks of low-density polymeric foam material disposed between the sheets. The weight of a sleeper is supported by magnetic repulsive force, and the two sheets are held in alignment with one another by the foam blocks. Contact of the upper sheet with walls or support structure of a sleeper cab is prevented, thus isolating the top of the structure from vibration.
