    Abstract: A boltless brace assembly for a rail includes a base block interlocked with a brace, and further includes a wedge to be inserted between an upper surface of the base block and a lower surface of the brace, thereby applying an upward force to the brace and a resultant downward force to secure the rail base. The brace assembly may be modified to provide a universal brace assembly, a resilient brace assembly, or a frog base clamp.

    Abstract: A rail brace assembly provides positive support for a stock rail mounted on a switch brace plate. The assembly includes a rail brace that it is installed over a fixed block attached to the brace plate. The block has a slot and a channel that accept a mating rib and tapered wings connected to the underside of the rail brace. The interaction of these elements provides vertical restraint for the rail brace. The brace assembly includes a stop that is secured to the brace plate and a tapered wedge that is disposed between the stop and the rail brace. Upon driving the wedge longitudinally of the rail, lateral force is applied to the rail brace and the rail. The stop and the wedge employ a longitudinally extending tongue and groove to prevent relative vertical movement therebetween. The junction between the wedge and the rail brace is defined by mating convex-concave surfaces. A shear member such as a cotter pin prevents the wedge from being retracted once the wedge has been driven to a desired longitudinal position. Because the wedge cannot be moved inadvertently, lateral force will be applied continuously to the rail brace by the wedge.

    Abstract translation: 轨道支架组件为安装在开关支架板上的库存轨道提供正向支撑。 该组件包括一个轨道支架，它被安装在固定在固定块上的固定块上。 该块具有狭槽和通道，其接纳与轨道支架的下侧连接的配合肋和锥形翼。 这些元件的相互作用为轨道支架提供了垂直约束。 支架组件包括固定到支撑板的止动件和设置在止动件和轨道支架之间的锥形楔形件。 当沿轨道纵向驱动楔子时，横向力被施加到轨道支架和轨道。 止挡件和楔子采用纵向延伸的舌部和凹槽，以防止它们之间的相对垂直移动。 楔形件和导轨支架之间的接合部由配合的凸凹表面限定。 一旦剪切构件如开口销一旦楔被驱动到期望的纵向位置就防止楔形件缩回。 由于楔不能无意中移动，横向力将通过楔形件连续施加到轨道支架。
