By means of a tie rod (not shown) between them the tongs are appropriately spaced from each other to engage the new rails previously positioned between the old rails. Both rail supporting tongs 19 are connected to the crane boom 2 by means of an open-link chain 21.
  • a similar pair of rail supporting tongs 20 are also pro vided beneath the vehicle frame 10, which tongs in the instant case are termed the rear rail supporting tongs and which are likewise suspended from an open-link chain 21.
  • the rear rail supporting tongs are similarly spaced from one another by a tie rod (not shown) so as to guide the new rails outwardly to the proper gauge.
  • Each of the rail supporting tongs 19 and 20 includes a pair of lugs or brackets 23 which have small rollers 24 attached to their ends.
  • the new rails 5 to be placed are received by the rail supporting tongs 19 and 20.
  • the lugs of each of the tongs are manually'spread apart, and the rail supporting tongs l9 and 20 are lowered over the rails until the lugs 23 are at the level of the railway track. Thereafter, the lugs are urged against each other so that they are positioned adjacent the railway track and the rollers 24 abut the lower faces of the rail heads.
  • the rollers 24 of the rail supporting tongs l9 and 20 now roll along the lower faces of the rail heads.
  • the correct spacing between the rails is maintained by the provision of the tie rods 20 which guarantee both at the front and at the rear rail supporting tongs l9 and 22, respectively, that the rails are positioned in their proper position for subsequent bolting to the ties.
  • the new rails 5 are raised by the rail supporting tongs l9 and 20, respectively, to such extent that the Thammer bolts on the ties may be left in position without becoming damaged or impeding the diverging movement of the new rails 5.
  • the front rail supporting tongs 19 have the special function of raising the new rails 5 in front of the crane vehicle 1 to a level above the Thammer bolts, and the rear rail supporting tongs 20 now guide the rails into the correct gauge of track for the subsequent bolting to the ties.
  • the new rails contact the track bed or foundation at the most at a distance of 3 or 4 meters rearward of the crane vehicle 1.
  • the illustrated apparatus includes a rubber tired vehicle bridging or spanning the railway track and being equipped at its front end and in the region of the vehicle frame as well as at its rear end with roller and guiding elements for raising the old rails, passing them along both sides of the vehicle and bringing them together to smaller gauge of railway.
  • the illustrated vehicle is also provided with further roller and guiding elements underneath the vehicle frame for guiding the new rails from their location within the gauge of railway into the position of the old rails.
  • the illustrated rubber tired vehicle is adapted to move with its wheel along either side of the railway track so that raising of the old rails and guiding of the new rails into the position of the old rails is not interfered with.
  • the illustrated vehicle is a crane vehicle or mobile crane which is equipped with a rail supporting frame including a pair of supporting arms at the front end.
  • the arms include front guiding rollers for the old rails to be raised.
  • at least one guiding or supporting roller is provided in the area of the rear end of the vehicle frame for each of the two old rails to be laid down in the inboard direction.
  • roller and guiding elements for guiding the new rails are formed as rail supporting tongs interconnected by means of a tie rod and pro vided with a pair of lugs adapted to be spread apart and having their ends provided with rollers by means of which they are adapted to engage underneath the rail heads in the manner of pliers or tongs.
  • This construction renders possible in advantageous manner to grip and precisely guide the new rails.
  • the front rail supporting tongs as illustrated are mounted on the boom of the crane vehicle by means of a suspending device, and the rear roller supporting tongs are mounted in the region of the rear portion of the crane vehicle, also by means of .a suspending device.
  • the suspending device may be constituted simply by an open-link chain.
  • the vehicle may be further provided with special axles and rimmed or spur wheels so that it is adapted to move on the railway track.
  • the method of the invention facilitates the replacement of old rails by new rails in one single operation and without any additional manipulation by workers.
  • the old rails to be removed are passed over the rollers in infinite length and laid down into the railway track, or optionally onto the tie beads, by means of the rollers of the trailer.
  • the wooden separators or washers may be easily replaced. Both rails to be removed are guided over the rollers which are positioned above the vehicles axles. At the same time, the two new rails are raised by means of the rail supporting tongs and moved from their location in the middle of the railway track into the position of the old rails, whereby exact alignment is provided by the tie rods.
  • the apparatus according to the invention is of surprisingly simple construction as the expert will recognize, because the new rails are placed into their final position in most simple manner, and the old rails are removed simply by causing portions of the apparatus to advance underneath them.
  • the boom of the crane vehicle is adapted to fulfill three functions:
  • New rails which are present in substantial lengths may be drawn by the boom of the crane vehicle so as to have exactly the proper spacing precisely at the rail butt joint to be welded. During such drawing operation, the rails may be drawn in such way that the subsequent welding operation need not be performed on a tie. To this end, the already placed rail is cut to the proper length, and the new rail is drawn into the desired positron.
  • the boom renders possible a lifting ofthe old rails at the beginning of the working procedure in order to introduce them under the crane vehicle or mobile crane.
  • the new rails are continuously raised by the boom during the advancing movement of the crane vehicle.
  • jointed rails can also be handled because the passages for the old rails can be selected to be of correspondingly great dimension. It is also advantageous that if the new rails do not terminate within the space between the ties, the next new rail as described above can be drawn in such manner that it can be weldedto the end of the preceding rail section within the space between ties. During the placement, the tie ends are initially positioned one above the other, and the trailer moves onto the uppermost, last new rail via an overrunning shoe.
  • a method for continuously exchanging an old pair of rails with a new continuous pair of ribbon rails on a tie bed by means of a rubber-tired vehicle comprising the steps of: rolling said rubber-tired vehicle along said bed in a forward direction with the wheels thereof disposed outwardly of said old rails and spanning both said new rails and said old rails, simultaneously lifting said old rails and said new rails at the front end of said vehicle from said tie bed, spreading said new rails apart while said old rails remain raised by said vehicle as said rubber-tired vehicle continues to travel with said old and new rails passing beneath said vehicle, lowering said new rails into the positions occupied by said old rails, spreading apart the old rails, and rearwardly of said vehicle lowering said old rails to positions outwardly of their previously occupied positions.
  • An apparatus for continuously replacing an old pair of rails with a new pair of continuous ribbon rails on a tie bed comprising a vehicle having a frame, rubber tires attached to and supporting said frame for rolling along said bed, said frame and said wheel having a predetermined span greater than the width between said old rails to allow said vehicle to roll along said tie bed at locations outwardly of said old rail locations, means on the front end of said vehicle for raising and supporting the old rails from the bed for traveling through said vehicle, means at the front end of said vehicle for raising and supporting said new rails simultaneously with the raising of said new rails, means on said vehicle for spreading apart said new rails to the gauge of said old rails as said vehicle rolls along said bed and said new rails travel through said vehicle, and means for shifting said old rails laterally and for lowering the same to said tie bed at locations adjacent said new rails.
