Abstract
A securing device for a railway rail includes a fixing rod having a first end in the form of a spring head which bears on the shoe of the rail. The rod extends through a shim and has a second end is configured like a hook and is held in an anchoring sheath embedded in a support. The anchoring sheath includes a shoulder for tensioning the spring head under the shoe of the rail after the rod has been rotated by a half turn. The tensioning of the rod also results from the slope of the upper surface of the shim which extends upwardly and continues the slope of the shoe of the rail.
Claims16
A securing device, for securing railway rails on cross ties, comprising a rod having a first end and a second end and a longitudinal axis, said first end including a spring head, shaped as an open ring, which is adapted to rest against a rail shoe, said second end including an inclined heel, off-centered from said longitudinal axis, defining a hook which is adapted to cooperate with a hooking surface, and means for progressively tensioning said spring head on the rail shoe, comprising a surface inclined upwardly in the direction of the rail shoe, for guiding said spring head of said rod to a position over the rail shoe as said spring head of said rod is moved by a half-turn around said longitudinal axis.
A securing device, for securing railway rails on cross ties, comprising a rod having a first end and a second end and a longitudinal axis, the first end including a spring head, shaped as an open ring which is adapted to rest against a rail shoe, said second end including a heel which is off-centered from the longitudinal axis, defining a hook which is adapted to cooperate with a hooking means, said securing device comprising two functionally operable means for tensioning said spring head on the rail shoe, said two means for tensioning said spring head on the rail shoe comprising:
- (a) a first means, including an upper surface which is inclined toward the rail shoe, for exerting a tensioning force on said spring head by rotating said rod by a half-turn, to move said spring head from a first position on said inclined upper surface to a second, higher position, on a portion of the rail shoe;
- and
- (b) a second means including an anchoring sheath having a shoulder for cooperating with said heel of said rod when said spring head is maintained in said second position, said shoulder being longitudinally downwardly inclined in the direction of the rail shoe to further exert a tensioning force on said spring head.
