  • FIG. l the invention is illustrated in conjunction with a machine for surface tamping the ballast alongside the track rails between adjacent ties, the ties 1 resting on ballast 3 and carrying track rails 2 on which the carriage frame 16 is supported for mobility on the track by means of running gears 17, 17.
  • the machine moves in the direction of the arrow, to the left in the drawing, and the surface tampers are shown mounted at the front end of the carriage frame 16.
  • a mobile surface tamping apparatus of this type may be used in track maintenance work immediately subsequent to the leveling and/or lining and tamping of the track, or it may be used independently.
  • each unit has four surface tampers 4 mounted in respect of a respective track rail and the ties in the manner best seen in FIG. 4.
  • the carrier elements extend on respective sides of a track rail 2 in vertical planes parallel thereto while the surface tampers of each pair are mounted on respective sides of a tie 1 for surface engagement with the ballast between adjacent ties.
  • a common crankshaft 7 extends in a plane vertical to the track and parallel to the ties.
  • the crank shaft supports the two carrier elements independently and for free movement perpendicular to the plane in which the shaft extends, i.e. in vertical planes parallel to the track.
  • the crankshaft has two crank portions whereon the carrier elements 5, 5 are joumaled laterally adjacent respective sides of the track rail (see FIG. 2), and the two crank portions are staggered in, relation to each other in the plane of the shaft.
  • a drive means constituted by motor 6, is provided for rotating the crank shaft and thereby to vibrate the carrier elements 5, which are freely suspended on the crank portions of the shaft, thus to impart vibration to the surface tampers 4. Since the crank portions are staggered in opposite directions, the vibrations imparted to the support means for the tamping unit will be properly balanced.
  • two like tamping units are vertically adjustably mounted symmetrically on a common central guide for surface tamping the ballast adjacent each of the track rails 2.
  • a support means supports each ballast tamping unit for free movement in the plane of its crankshaft or a plane parallel thereto, i.e. transversely of the track.
  • the support means for each ballast tamping unit includes a main carrier member 10 and an intermediate carrier member 8.
  • a pivot pin 9 extending in the direction of track elongation interconnects the main and intermediate carrier members so that the intermediate member 8 is pivotal on the main member 10 in a direction transversely to the track.
  • the surface tampers 4 are freely movably in directions parallel and transverse to the track elongation for proper contact with ballast portions to be tamped thereby.
  • the main carrier member is a two-armed bracket whose arms extend in opposite directions from the vertical guide post 12 towards the track rails 2, 2, the centrally positioned vertical guide serving to mount the bracket 10 vertically adjustably on the apparatus.
  • the vertical guide post 12 is mounted between two brackets extending from a sliding block 14 which runs on transverse rails at the front end of the carriage frame 16 so as to enable the ballast-tamping units to be transversely moved in respect of the track.
  • This transverse movement may be effected by a hydraulic motor 15 connected to the sliding block.
  • Another hydraulic motor 13 is mounted on one of the brackets supporting the vertical guide post and has its piston rod connected to the support bracket 10 of the ballast-tamping units to provide a drive for vertically moving the units and for exerting downward pressure thereon to force the units and for exerting downward pressure thereon to force the vibrating surface tampers into engagement with the surface of the ballast during tamping.
  • ballast broom 18 is mounted at the rear end of the carriage frame on pivotal carrier arms 19 so as to be movable: into and out of engagement with the railroad bed.
  • Ballast brooms useful for this purpose usually comprise lengths of hose or like flexible elements extending radially from a rotatable shaft to clean the surfaces of the ties and evenly to distribute the ballast over the entire bed.
  • a machine of this type may include a carriage frame 20 having a front portion which vertically adjustably supports two tamper units 21 arranged for simultaneously tamping the ballast underneath two adjacent spaces between ties l. Tampers of this type have been disclosed and claimed, for instance in our U.S. Pats. Nos. 3,372,651 and 3,357,366. Combining the surface tampers of the present invention with this type of machine has the particular advantage that surface tamping will be simultaneously effected in the same number of spaces as tamping under the ties.
  • track-leveling and -grading machines include a track-raising apparatus 22 at the front end of the machine whose operation is controlled by a reference system including the stop 23 cooperating with a with reference line 24 extending to point 25 supported in fixed relationship to the previously graded track portion on which it rests.
  • the track-lining apparatus 26 is mounted intermediate the running gears of elongated carriage frame 20, all of this structure being conventional.
  • the surface tamping units of the present invention are mounted at the rear end of carriage frame 20 in a manner similar to the mounting shown at the front end of the carriage frame in FIG. 1.
  • the vertical guide post 12 is also movable on its support bracket in the direction of track elongation by adjustment means 27.
  • FIG. 4 shows the surface tamping units in operative position in relation to the track, a preceding position being indicated in broken lines.
  • the main carrier member may be joumaled on the vertical guide post for rotation about the axis thereof.
  • crankshaft of the surface-tamping unit has been shown to extend transversely of the track and the tamper carrier elements accordingly in the direction of track elongation, this relationship could be reversed so that the tampers are mounted for free movement on the crank shaft in a plane extending in the direction of the ties.
  • crank shaft and the vertically adjustable support means therefor are so arranged that the downward pressure on all the tampers freely suspended from a common crankshaft is always evenly distributed and that each tamper pair may be individually adjusted in relation to the ballast surface.
  • a mobile apparatus for simultaneously tamping the ballast along each side of a track rail and along each side of a tie between adjacent ties of a track comprising 1. a ballast-tamping unit associated with each of the rails,

  • two carrier elements each consisting of a crossmember and two legs extending from the cross member, a respective one of the pairs of surface tampers being fixedly mounted on a respective one of the two legs of a respective on of the carrier elements, said carrier elements extending in first parallel planes perpendicular to the track plane, and
  • a common support means extending in a second plane perpendicular to the first planes and to the track plane, one of said first and second planes extending in the direction of the track rails and the other one of said planes extending in the direction of the ties, the common support means pivotally supporting the two and in such alignment that each two of said surface tampers are positioned in planes parallel to the second p ane whereby the four surface tampers of each ballast-tamping unit are positionable along each side of a track rail and along each side of a tie at a point where the rail and the tie intersect carrier elements for free movement in the second plane; and
  • the common support means comprises a common crankshaft extending in said second plane through the two carrier elements for vibrating the two carrier elements and the surface tampers fixedly mounted thereon, the carrier elements being pivotally supported on the crankshaft.
  • crankshaft has two crank portions whereon the two carrier elements are journaled, the two crank portions being staggered in ralation to each other.
