  • the tamping tools are vibratory and reciprocable in the direction of track elongation.
  • present-day track tampers also include means for grading or leveling the track, including a track-lifting means 9 at the front end of the overhanging portion of the carriage frame, and a reference system in respect of which the track is leveled, this system including a reference line 10 extending from a front bogiie 11 in the uncorrected track section to a rear station 12 resting on thecorrected track section.
  • the reference system also includes a stop 13 (and I3 in FIG. 3) cooperating with the reference line and resting on the track section being tamped by each track tamping assembly. All of this structure and its function are well known.
  • a separate tamping tool assembly each consisting of a series of pairs of associated opposed tamping tools, is mounted on a carrier vertically above each rail, of the track.
  • a common or central lubricating medium supply' source 7 is connected by a lubricating medium supply conduit system to all lubricating points of the tamping tool assemblies so that all assemblies have a common lubricating system although each assembly is enclosed in a housing defining a common sump for the lubricating medium for each assembly.
  • each tamping tool assembly includes a series of two pairs of opposed tamping tools, and the pairs of tools are so spaced from each other in the direction of track elongation that the tools of each pair which are adjacent to each other are at smaller distance from each other than the distance between adjacent ties whereby the adjacent tools of the two pairs may be immersed in the ballast between the adjacent ties.
  • each assembly associated with a respective track rail is housed in a separate carrier 5', the two housings are again connected to the same lubricating medium supply 7 (see also FIG. 8). However, it is also possible to mount the assemblies for both rails in a single housing.
  • twin units 5' are mounted for movement in relation to each other along the direction of track elongation.
  • the carriage frame 1' is of bridgelike configuration and runs on swivel trucks 2', 2' supporting a respective end of the carriage frame.

  • the track-lifting means 9 is mounted at the front end of the support frame and, if laterally movable, may also serve for track lining.
  • a hydraulic jack engages the track rails between the two twin track tamping assemblies in the center of the support frame 14 and, if the machine also serves as a track liner, this jack may be laterally movable to serve for lining the track at this point.
  • jack 15 serves primarily to press downwardly against the track and thus to prevent unwanted upward movement of the track at this point and thus to maintain the track in the graded position.
  • four separately housed twin track tamping assemblies of this type may still be centrally supplied from a common lubricating medium source 7.
  • the tamping tool assembly carrier is constituted by a common housing 16 defining a sump for a lubricating medium, such as oil.

  • the lower portion 18' of the tamping tools constitutes a mount for tamping tool jaw 18.
  • the housing 16 has a bottom formed with concave portions accommodating respective pivots 19 of the tamping tools which are flooded with lubricating oil. Suitable sealing means constituted by gaskets 19' are provided around the tamping tool pivots for preventing leakage of oil through the housing bottom.
  • the upper and lower tamping tool portions are detachably connected by means of a bolt 22 extending transversely to the axis of the tool, as best seen in FIG. 7, a sealing gasket 23 being interposed between the forked upper end of the lower tamping tool portion 18' and the lower end of the upper tamping tool portion 21 fitting into the forked upper end of the lower tool portion.
  • the relative angle of the tamping tool portions in respect of each other may be readily adjusted while the gasket 23 remains in place so that the distance between the lower ends of the tools of each pair may be changed, for instance to tamp double ties.
  • each housing 16 consists of detachably connected wall portions 16, 16", which may be bolted together along their mating flanges so that the housing may be opened for access to the parts mounted therein, the shafts or pivotal mountings for the moving parts in the housing being supported in the housing wall.
  • housing into two or more wall portions thus makes it possible readily to replace individual parts in the housing by removing one of the wall portions temporarily.
  • the housing for the track-tamping assembly associated with a respective one of the track rails comprises a center portion 16" and two lateral portions 16', 16' detachably fastened to the center portion along flanges extending in vertical planes parallel to the direction of track elongation so that the lateral wall portions may be selectively removed for access to the interior of the housing.
  • Suitable sealing means or gaskets extend between the flanges of the housing portions so that the wall of the housing will be sealed against oil leakage in the assembled condition.
  • FIG. 7 also shows the pulley and belt drive 38 for driving cam shaft 24 which serves as a common tamping tool vibrating means for all the tamping tools.
  • the cam shaft is journaled in the housing wall and extends in a plane which is transverse and vertical to the track, and runs centrally between columns 17, 17 on which the housing and tamping tool carrier is mounted for vertical movement.

  • Separate drives 26 and 27 are connected to the upper ends of each tamping tool of a pair (the three associated pairs being mounted on the same shafts and, therefore, being driven therewith).
  • the drives reciprocate the opposed tamping tools in the direction of track elongation, the illustrated drives being hydraulic motors.
  • a transmission element 28 is mounted in the housing 16, which holds all the shafts and pivotal mountings of the track-tamping assembly, the fulcrum 29 of the transmission element being mounted on the housing wall independently of the camshaft.
  • each transmission element 28 is linked to a respective transmission element 28 by means of interposed drives 26, 27; and each transmission element is at least indirectly connected to the vibrating means, being linked to the outer ends of the camshaft arms
  • the transmission element is advantageously a lever having two arms, a bell crank lever being illustrated in FIG. 4.

  • each pair of opposed tamping tools is associated with one common transmission element, the structure being identically duplicated for each pair of the twin-tamping tool assembly (the three associated pairs moving in unison with the driven pair).
  • the two arms of the transmission lever 28 extend at an angle to each other, which angle faces the vertical plane wherein the camshaft axis extends, and the upper transmission lever arm is connected to the associated vibrating arm 25.
  • the fulcrum 29 of the transmission lever is positioned below a horizontal plane defined by the camshaft axis in the embodiment of FIG. 4.
  • the upper end of the tamping tool farther removed from the camshaft is linked to the arm of the transmission lever extending upwardly from fulcrum 29, and the upper end of the tamping tool closer to camshaft 24 is to the arm of the transmission lever extending downwardly from fulcrum 29. In this manner, the tamping tools of each pair are vibrated in opposite directions.
  • the length of the reciprocating stroke of the opposed tamping tools of each pair may be further varied by providing adjustable stops 30 for the reciprocating movement of the outer tool of each pair.
  • a fixed stop may be mounted on the cylinder of hydraulic motor 26 and a movable stop 30 for selective engagement therewith may be mounted so as to be movable into the path of the cylinder movement by a hydraulic motor or like drive 31.
  • the movable stop 30 will engage the fixed stop and thus limit further movement when the stop 30 is swung into the path of the cylinder movement of hydraulic motor 26 by drive 31.
  • the distance between the opposed tools of each pair is further adjustable by changing the angle between the upper and lower portions of the tools.
  • the housing 16 encloses only a part of the tamping tool assembly, i.e. only the pivots 19 of the tamping tools are immersed in a lubricating medium sump in the housing.
  • the lubricating points of the other pivotal mountings and drives for the tamping tools 6 are supplied from a common or central supply of lubricating medium 7 by a lubricating medium conduit system 32.
  • the kinematic system for connecting the upper tamping tool ends to the camshaft arms 25 also differs from that of FIG. 4, the transmission element 28' being a straight two-armed lever one of whose arms is connected to the camshaft arm at the same point as the drive 26' while the other transmission lever arm is connected to drive 27' of the opposing tamping tool.
  • the lubricating conduit system 34 includes a pump 33 which delivers lubricating medium to a device 35 for conditioning the medium, such as an oil filter and/or an oil-cooling system. The reconditioned oil is then delivered into housing 16 and to the various lubricating points of the track-tamping assembly, and leaves the sump at the bottom of the housing by gravity through an outlet whence the used lubricating medium is returned into the conduit system by pump 33. In this manner, the oil may be used for an extended period oftime without being changed.
  • FIG. 6 also shows some preferred delivery means for the lubricating medium to lubricate assembly points positioned outside the sump, such as spray nozzles 36, oil distributing baffles 37, which may simply be cast ribs in the housing wall, etc., all of which serve adequately to provide lubrication for all moving parts of the assembly within the housing.
  • spray nozzles 36 oil distributing baffles 37, which may simply be cast ribs in the housing wall, etc., all of which serve adequately to provide lubrication for all moving parts of the assembly within the housing.
  • While such oil distributing means are of particular advantage in an enclosed housing, they may also find use in an arrangement similar to that of FIG. where the sprayed or other distributed oil may then be further directed into the sump in the housing therebelow whence it may be recirculated in a similar manner as described in connection with FIG. 6.
