Abstract
Rail construction including laterally adjacent frog sections with guard rails outwardly spaced to each side thereof by interposed liners. The components are interconnected by a transverse tightened bolt with vertical misalignment precluded by either nesting projections on adjacent abutting faces of the components or by a rigid, preformed sleeve press-fit within the bore receiving the bolt, the sleeve extending through the frog sections and at least partially through the liners.
Claims20
Rail construction including a frog comprising two laterally positioned, elongate rail sections with first, laterally adjacent, abutting faces, one on each said rail section, guard rails laterally outward of said rail sections to opposed sides of said frog, a liner interposed between and engaged with each said guard rail and a corresponding said rail section for maintaining the laterally outward position of said guard rails, each said liner and the corresponding rail section having second abutting faces thereon, each of said first and second abutting faces having spaced projections thereon, said projections on each said abutting face inter-nesting with the projections on a corresponding said abutting face, and weld-free connecting means clamping said guard rails, liners and frog rail sections together with said projections nested wherein lateral separation is precluded by a bolt, and transverse movement of said rail sections relative to each other and to said liners is prevented by said inter-nesting projections.
Rail construction including a frog comprising two laterally abutting, unwelded rail sections, guard rails laterally outward to opposite sides of said frog, a liner interposed between and engaged in a weld-free manner with each guard rail and a corresponding said side of the frog, a laterally extending bore defined through said rail sections, said liners and said guard rails, a preformed, rigid, elongate sleeve extending within said bore through and in intimate fixed engagement without play with said rail said sections and at least a substantial portion of each of said liners immediately adjacent said rail sections, said sleeve having ends terminated in the bore at said liners, wherein transverse movement of said rail sections and said liners, relative to said bore and said sleeve, is precluded, a connecting bolt engaged through said sleeve and bore, and tightening means beyond said guard rails for tensioning said bolt between said guard rails for a weld-free joining of said rail sections, liners and guard rails.
