Definitions

  • CT Railway ballast tamping mechanism has an oscillatable shaft [21] Appl 64351 terminating at its lower end in a nose which has a lateral bore. A pair of tamping tool supports have similar lateral bores 52 U.S. Cl.
  • the nose has four of such faces, two on each side of and adjoining UNITED STATES PATENTS said plane, and the supports have opposed pairs of faces correspondingly inclined to mate with the nose faces so that any i ggg g f; f t
  • This invention relates to railway ballast tamping mechanism wherein tamping tools at the lower end of an oscillatable shaft are inserted into railway ballast and the shaft is driven to make the tools work the ballast.
  • a railway ballast tamping mechanism comprising a vertical shaft adapted to be driven in an oscillatory manner about its longitudinal axis, and a pair of tampering tool supports adapted to be mounted on the lower end of said shaft, said tool supports having confronting surfaces which meet in a plane which contains the longitudinal axis of said shaft, said shaft having a nose at the lower end thereof, said nose having an aperture therethrough at right angles to said plane, said tool supports having similar apertures therethrough for alignment with the nose aperture when assembled, a bolt for passage through the aligned apertures, a nut for the end of said bolt, said tool supports having confronting recesses in said confronting surfaces to receive the nose, the nose and the tool supports having downwardly and inwardly inclined mating faces on either side of said plane, the inclinations of said faces being such that any tendency of the tool supports to be pushed up along the nose as they are being forced downward into railway ballast to be tamped causes said tool supports to be urged away from one
  • the tamping mechanism shown has a shaft 1 adapted to be oscillated about its longitudinal axis 2 by suitable known drive means (not shown) at the upper end of the shaft.
  • the shaft has a nose 3 at its lower end, which has lateral surfaces 4 on either side of and equally spaced from a vertical plane 5 which contains the axis 2.
  • a bore 6 extends through the nose from one lateral surface 4 to the other.
  • a pair of wedging surfaces 7, 8 are formed on the nose and a similar pair are formed on the diametrically opposite side of the nose, each of these surfaces extending inwardly both from top to bottom and laterally from plane 5.
  • a pair of tool supports 9, 10 are adapted to be mounted on the nose 3 and carry tools in the form of tamping blades 11.
  • Each support has a bore 12 adapted to be aligned with the bore 6 to receive the shank 13 of bolt 14 which cooperates with nut 15 to hold the nose and the supports in assembled condition.
  • the support 9 has faces 16 which mate with the faces 7 on the nose and the support 10 has faces 17 which mates with the faces 8. These faces 16 and 17 form the sides of recesses 18 which are formed in confronting faces 19 of the supports. In the embodiment shown, the recesses divide the confronting faces, in each case, into two face parts and 19b.
  • railway ballast tamping mechanism comprising a vertical shaft adapted to be driven in an oscillatory manner about its longitudinal axis, and a pair of tamping tool supports adapted to be mounted on the lower end of said shaft, said tool supports having confronting surfaces which substantially meet in a plane which contains the longitudinal axis of said shaft, said shaft having a nose at the lower end thereof, said nose having an aperture therethrough at right angles to said plane, said tool supports having similar apertures therethrough for alignment with the nose aperture when assembled, a bolt for passage through the aligned apertures, a nut for the end of said bolt, said tool supports having confronting recesses in said confronting surfaces to receive the nose, the nose and the tool supports having mating faces on either side of said plane which are inwardly inclined both from top to bottom and laterally from said plane such that any tendency of the tool supports to be pushed up along the nose as they are being forced downward into railway ballast to be tamped causes said tool supports to be urged away from one another to place said bolt in tension.
