The measuring device comprises a carrying frame (7) guided by the rails (2, 2') and driven along it through a railroad vehicle to which it is connected through the intermediary of hinges enabling a vertical and lateral displacement of said frame (7) with respect to the vehicle. The carrying frame (7) is provided with a plurality of feelers, cooperating with the surface of the head (12) of the rail (2) transversally spaced apart the ones from the other. The carrying frame (7) comprises a guiding dihedral used as reference base, the edge of which is parallel to the longitudinal axis of the rail (2), applied against the upper part of the rolling surface of the rail (2) and the lower part of the internal face of the head (12) of the rail. This guiding dihedral (2) carries at least one hinging shaft (21) which extends parallely to the edge of the guiding dihedral (2) on which at least two mechanical feelers (16,17) are pivoted, said feelers contacting the rail ( 2) in a measuring zone extending transversely to the surface of the head (12) of the rail.

1. Continuous on track measuring device of the transverse profile of the useful portion of the head of at least one rail of a railroad track comprising a bearing frame, guided by the rails, and pulled along them by means of a railroad vehicle to which it is connected through hinges permitting vertical and lateral displacements of said frame with respect to the vehicle, this bearing frame being provided with a plurality of feelers, cooperating with the surface of the head of the rail, displaced the ones with respect to the others transversely to the rail, characterized by the fact that the bearing frame comprises a guiding dihedral forming a rerefence base, the edge of which is parallel to the longitudinal axis of the rail, applied against the upper, portion of the rolling surface and against the lower portion of the internal face of the head of the rail; and by the fact that it comprises at least one hinging shaft parallel to the edge of the guiding dihedral on which are pivoted at least two mechanical feelers, measuring at least two different sidelines of the rail, provided with pin-point contact members intended to enter in contact with the rail in a measuring zone transverse to the surface of the head of the rail. 2. Device according to claim 1, characterized by the fact that the shaft on which the feelers are pivoted is laterally displaced on one side of the middle longitudinal plan of the rail and by the fact that the contacts of at least two of said feelers cooperate with points of the surface of the head of the rail located on the other side of said middle plan of the rail. 3. Device according to claim 2, characterized by the fact that it comprises two parallel shafts mounted on the bearing frame, located on either side of a vertical plan passing through the longitudinal axis of the rail, each of these shafts serving to pivot at least two mechanical feelers. 4. Device according to claim 3, characterized by the fact that each feelers comprises two arms, hinged on said shafts, the free ends of which are connected through a bar on which is fixed the contact member. 5. Device according to claim 4, characterized by the fact that the feelers hinged on the same shaft are, seen from above, located the ones inside the others, and by the fact that the contact member of all the feelers are substantially aligned on the trace formed by the intersection of a plan perpendicular to the rail with the surface of the head of said rail. 6. Device according to claim 5, characterized by the fact that, seen from above, the arms of a feeler pivoted on one of the shafts are located between the arms of two feelers pivoted on the other shaft. 7. Device according to claim 5, characterized by the fact that, seen from above, the adjacent arms of two feelers pivoted on a same shaft are located between the arms of two feelers pivoted on the other shaft. 8. Device according to claim 4, characterized by the fact that it comprises at least three feelers the contact members of which cooperate with the rolling surface of the rail and at least two other feelers the contact member of which cooperates with the inside edge of the rail. 9. Device according to claim 8, characterized by the fact that it comprises further at least two feelers the contact member of which cooperates with the outside edge of the rail. 10. Device according to claim 8, characterized by the fact that it comprises lifting means of all the feelers simultaneously controlled by a same control member located on the path of a counter-rail. 11. Device according to claim 8, characterized by the fact that it comprises lifting means of all the feelers simultaneously controlled by a same control member located on the path of a counter-rail and by the fact that it comprises further retracting means of the feelers the contact member of which cooperates with the outside edge of the rail, controlled by a second control member independent from said other control member. 12. Device according to claim 1, characterized by the fact that the bearing frame is provided with vertical guiding pads, intended to rest on the rolling surface of the rail, located on either side of the group of feelers, and by the fact that these pads are hinged on the said bearing frame on axes extending perpendicularly to the longitudinal axis of the rail. 13. Device according to claim 12, characterized by the fact that the bearing frame is provided with lateral guiding pads, hinged on the said bearing frame on axes extending perpendicularly to the longitudinal axis of the rail, intended to enter in contact with the inside lateral face of the rail, located on either side of the group of feelers. 14. Device according to claim 10, characterized by the fact that it comprises two bearing frames each associated to one rail of a railway track, that it comprises spreading means tending to spread these frames apart and to apply the lateral guiding pads against the internal surface of each rail, and by the fact that the control member of the lifting means of each bearing frame is located on the path of a counter-rail associated to the rail cooperating with the other bearing frame. 15. Device according to claim 14, characterized by the fact that the control members of the lifting means of the feelers are provided with a cam cooperating with a lug fast with the guiding frame of the device causing simultaneously with the lifting of said guiding frame the retraction of said feelers. 16. Device according to claim 1 characterized by the fact that it comprises at least eight mechanical feelers, one of which at least being retractable independently from the others. 17. Device according to claim 13, characterized by the fact that it comprises two bearing frames each associated to one rail of a railway track, that it comprises spreading means tending to spread these frames apart and to apply the lateral guiding pads against the internal surface of each rail, and by the fact that the control member of the lifting means of each bearing frame is located on the path of a counterrail associated to the rail cooperating with the other bearing frame.
