Clamp for fastening a rail ferroviario, process of manufacture of a clamp, together to set a path ferroviario and process of installing a clamp

摘要

A clip for fastening a railway rail to a rail foundation is proposed, which clip is made of a rod of resilient material such that it has at least one bent portion of which the axial cross-sectional area is greater than that of the remainder of the clip. In one embodiment of the clip, the clip comprises, proceeding along the rod from one end thereof to the other, a first portion (1) which is substantially straight, the said one end of the rod constituting a free end (1b) of the said first portion (1), a second portion (2) which is a reverse bend, a third portion (3), a fourth portion (4) which is another reverse bend, and a fifth portion (5), the construction of the clip being such that it can be placed in a position in which a longitudinal axis of the first portion (1) extends horizontally and the third and fifth portions (3, 5), when viewed from above, appear to lie on opposite sides of the said first portion (1), wherein the axial cross-section of more than a tenth of the length of the said first portion (1) of the clip is smaller in area than the axial cross-section of at least a region of the said second portion (2) of the clip. Such clips may be made of less material as compared with some prior art clips intended for the same purpose, thereby being cheaper to make. IMAGE
