Device for tamping railroad track adjacent the tie ends thereof

A tamping device for tamping railway track ballast adjacent and beneath the track tie ends, comprising a track working machine;

• a retractable tamper frame mounted on the machine;
• said frame in operative position, extending substantially parallel to the center line of the track adjacent and outside the tie ends thereof;
• a plurality of tamping plate means mounted one behind the other longitudinally of the frame and extending inwardly thereof, in the direction of the track center, in stepped formation with a leading tamping plate means extending farther from the frame inwardly towards the track center than a next adjacent trailing tamping plate means;
• each tamping plate means having a leading edge and a trailing edge, one of said edges being flexibly connected to said frame and the other of the edges being connected to positive displacement tamping plate means vibrator means mounted on said frame to drivingly vibrate the tamping plate means relative to said frame.

A tamping device for tamping railway track ballast adjacent and beneath the track tie ends, comprising a track working machine;

• a retractable tamper frame mounted on the machine;
• said frame in operative position, extending, at least partially in the ballast, substantially parallel to the center line of the track adjacent and outside the tie ends thereof;
• a plurality of tamping plate means mounted one behind the other longitudinally of the frame and extending inwardly thereof, in the direction of the track center, in stepped formation with a leading tamping plate means extending farther from the frame inwardly towards the track center than a next adjacent trailing tamping plate means;
• each tamping plate means having a leading edge and a trailing edge, one of said edges being flexibly connected to said frame and the other of the edges being connected to positive displacement tamping plate means vibrator means mounted on said frame to drivingly vibrate the tamping plate means relative to said frame;
• and a ballast plough mounted at a leading end of said tamper frame said plough comprising a rearwardly upwardly inclined ramp surface and a ballast share blade extending above said ramp surface from a point adjacent the nose of the plough rearwardly towards the trailing end thereof.

A tamping device for tamping railway track ballast adjacent the track tie ends, comprising a track working machine;

• a tamper frame mounted on said machine;
• said frame, in operative position, extending substantially parallel to the rails of the track adjacent the tie ends thereof;
• a plurality of longitudinally extending tamping plate members mounted one behind the other on the frame and extending inwardly thereof towards the track center in stepped formation;
• each tamping plate member having a leading edge and a trailing edge, one of said edges being flexibly connected to said frame and positive displacement means mounted on the frame for drivingly vibrating the other of said edges relative to said frame and means to adjust the attitude of at least one plate member relative to said tamper frame.

A tamping device for tamping railway track ballast adjacent the track tie ends, comprising a track working machine;

• a tamper frame mounted on said machine;
• said frame, in operative positon, extending substantially parallel to the rails of the track adjacent the tie ends thereof;
• a plurality of longitudinally extending tamping plate members mounted one behind the other on the frame and extending inwardly thereof towards the track center in stepped formation;
• each tamping plate member having a leading edge and a trailing edge, one of said edges being flexibly connected to said frame and positive displacement means mounted on the frame for drivingly vibrating the other of said edges relative to said frame and means on the tamper frame to move the trailing edge of at least one plate member closer to the track center.
