摘要： A low maintenance rail seat has recess in the concrete tie and an abrasion plate that covers the floor of the recess and its sides parallel to the rail base. The abrasion plate includes ribs which seat in additional recesses in the tie to retard longitudinal movement. The anti-abrasion assembly preferably has four flanges which wrap around the top of concrete tie to prevent dust particles from entering and abrading the concrete rail seat. These flanges also wrap around the support shoulder for additional resistance to longitudinal movement. The components are designed to provide 8.5″ of lateral support along the side of the rail base while the traditional e clip fastener provides only 3″ of lateral support. The interlock feature between the anti-abrasion assembly and the concrete tie also minimizes relative movement between abrasion plate and concrete tie, which results in less concrete surface abrasion.

摘要： A rail clip for fastening railway rails to rail ties. The clip consists of U-shaped member formed from metal plate having a base with a free end and the other end curving upwards with an internal radius of 18 mm or less and a short straight section followed by a second curve and two tapered arms extending therefrom or beyond the curve, said base adapted to be secured to said tie outwardly spaced from the foot of said rail, said arms being bent downwards in a third curve beyond said base and finally the tip portion of said arms being bent backwards in a forth curve toward and short of said base to form toes which are orientated for contact with the top surface of the rail base such that said arms and toes are deflected upwards relative to said rail to develop downward clamping forces at the said toes which hold the said rail on the said tie to restrain longitudinal, lateral and vertical movement; after the said clip is formed it is hardened and tempered and then cold set by loading it in the same manner as occurs in track but the applied load is increased until the yield is passed and the clip is permanently deformed, the load is then removed & the process is repeated at least once.
摘要翻译： 用于将铁路轨道固定到轨枕的轨道夹。 夹子由金属板形成的U形构件形成，其具有带有自由端的基部，另一端向上弯曲，内部半径为18mm或更小，并且具有短的直线部分，随后是第二曲线，以及两个从其延伸的锥形臂 或者超出曲线，所述基座适于被固定到所述导轨的与所述轨道的脚部向外间隔开的位置，所述臂在第三曲线中向下弯曲超过所述基座，并且最后所述臂的尖端部分在第四曲线中向后弯曲 朝向和短于所述基座以形成脚趾，所述趾部被定向成与轨道基座的顶表面接触，使得所述臂和脚趾相对于所述轨道向上偏转，以在所述脚趾处产生向下夹持力，所述趾部将所述导轨保持在 所述领带限制纵向，横向和垂直运动; 在形成所述夹子之后，其被硬化和回火，然后通过以与轨道中发生的相同的方式加载来冷却，但是施加的负载增加直到产量通过并且夹子被永久变形， 该过程至少重复一次。

摘要： A flat bar elastic rail clip in which the flat bar is turned back on itself so that one portion is longer than the other. The flat bar incorporates an opening in both portions to accommodate a rail spike that is held in the rail tie. This type of spike is usually used in combination with a concrete tie and a guide plate that seats on the rail seat of the tie. The combination of a shaped flat bar clip which is capable of providing both rail clamping and rollover protection configurations in combination with a guide plate and spike.
