  • Patent number: 6758406
    Abstract: A brace assembly provides support to a railroad rail, such as for a switch. The rail is supported on a tie plate. A wedge block is secured to the tie plate adjacent the rail. A groove is located in the inner wall of the wedge block. The groove extends longitudinally between the side walls and is spaced between the upper and lower sides of the wedge block. A brace has a tapered upper edge and a tapered lower edge that engage the rail. The brace has a tongue that extends outward from the base into the groove. The tongue and groove have widths that decrease from one side to the other. Moving the brace longitudinally relative to the wedge block enables the brace to be wedged between the wedge block and the rail. A spring clip secures the brace to the wedge block.
