"DEVICE FOR CONTROLLING A RAILROAD TRACK MAKING OR REPAIRING MACHINE" ABSTRACT OF THE DISCLOSURE This device for controlling a railroad track making or repairing machine comprises on the one hand a single laser emitter mounted on a skip standing on the track or the lay-out ahead of the machine, notably a tamping, levelling or sweeping beam in a horizontal plane and a second fan-shaped or sweeping beam in a vertical plane, and on the other hand two laser receivers mounted on the machine and adapted to adjust themselves automati- cally as a function of the impact line of one or the other of said laser beams at positions corresponding to the de- sired positions of the working members of the machine, the laser emitter being mounted on a support permitting its rotation about its track-parallel axis between two end positions spaced 90 degrees apart, these angular posi- tions corresponding the one to the beam in the horizontal plane for levelling operations and the other to the beam in the vertical plane for shifting operations. In a modi- fied version the laser emitter is fixedly mounted and it is only the optical system generating the fan-shaped or sweeping beam that is rotated through 90 degrees by means of a motor.
