发明名称 Railroad crosstie
摘要 A plurality of elongated, substantially planar, elastomeric members are assembled together in a stack such that the members are generally aligned with each other. The members are made of tire treads. An elongated, substantially planar, rigid first plate is positioned on top of and aligned with the stack of members. An elongated, substantially planar, rigid second plate is positioned beneath and aligned with the stack of members. Fastening apparatus is provided for holding the first plate, the second plate and the stack of members together. The fastening apparatus includes bolts or rivets which penetrate the plates and the stack of members, forming a non-perpendicular angle with a longitudinal axis of the members. An anchoring apparatus is provided for anchoring a first rail to a first end of the crosstie, and for anchoring a second rail to a second end of the crosstie.
