Abstract: 986,144. Fastening railway rails. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL. Jan. 22, 1962 [Jan. 20, 1961], No. 2294/62. Heading E1G. A railway rail is fastened to a concrete sleeper by means of a clip, one end of which engages the rail foot, the other end carrying a ridge which engages in a notch in the top face of the sleeper, and a bolt passing through an aperture in the clip into a well in the sleeper, both the aperture and the well being of slightly larger cross-section than the bolt shank. And the bolt shank engaging the well only with its side remote from the rail and engaging the wall of the aperture only with its side nearest the rail. As shown a threaded bolt 4 passing through a well 6 in a sleeper 1 and anchored by a plate 8 carries a clip 11 at its upper end one end of which bears on the rail foot 2. The other end 13 is received in a notched portion 14 of the sleeper, the notched portion preferably being lined with asphalt. The aperture in the clip through which the shank 4 passes is of slightly larger cross-section than the shank itself and the arrangement of sleeper, plate, bolt and clip is such that the bolt shank engages the outer wall A of the well 6 and inner wall B of the aperture in the clip 11, which arrangement transmits side thrust F from the rail to the sleeper over a relatively large region of a section of the sleeper which is compressed by the heel 13 and thus strengthened. A small clearance is preferably left between the heel 13 and the notch 14 so that contact is only established at C after the bolt has been subjected to side thrust from the rail. The well 6 may have a metal liner on its outer wall A.
