This invention relates to an insert for fixation of a railway clip comprising an inner conduit, parallel to the rail, intended to receive the rectilinear central portion of the clip, a horizontal rear face on which abuts the rear portion, parallel to the rail, of the clip which is joined to the central portion by a 180.degree. bend and which then extends towards the rail, above the inner conduit, by a substantially perpendicular loop whose end comes into abutment on an insulating stop resting on the base of the rail, wherein the upper face of the insert comprises, towards the inlet orifice of the inner conduit, a retaining boss against which the loop of the clip comes into bearing contact to maintain the clip in a position of equilibrium, where the free end of the central portion is placed in the inlet orifice of the inner conduit.
A rail mounting assembly for fixing the rail of a railway comprising an insert and a clip, said insert including an axially extending conduit having an inlet orifice, a retaining boss on said insert, said boss having an upwardly directed arcuate surface disposed generally perpendicularly to said conduit, upwardly directed stop means adjacent said arcuate surface, a resilient clip adapted to be connected to said insert, said clip including an elongate central portion adapted to be received in said conduit, said central portion having a free end, a loop portion on said clip, the axis of said loop portion being perpendicular to the axis of said central portion, the exterior of said loop portion having a radius of curvature complemental to said arcuate surface, said clip being dimensioned such that when said loop portion of said clip engages said stop means, axial relative movement of said central portion away from said insert portion is prevented and said free end of said central portion is gravationally maintained in registry with said inlet orifice.
A rail mounting assembly for fixing the rail of a railway comprising an insert and a clip, said insert including an axially extending conduit having an inlet orifice, a retaining boss on said insert, said boss having an upwardly directed arcuate surface disposed generally perpendicularly to said conduit, a resilient clip adapted to be connected to said insert, said clip including a elongate central portion adapted to be received in said conduit, said central portion having a free end, a loop portion on said clip, the axis of said loop portion being perpendicular to the axis of said central portion, the exterior of said loop portion having a radius of curvature complemental to said arcuate surface, said clip being dimensioned such that said central portion of said clip is gravationally maintained in coaxial alignment with said conduit with said free end of said central portion in proximate relation to said inlet orifice when said loop is disposed on said arcuate surface of said boss, said boss being laterally displaced from a vertical plane extending through the longitudinal axis of said conduit whereby said clip may be removed from said insert solely by combined initially axial and subsequent pivotal movement of said clip relative to said insert.
