Abstract

A self-propelled machine having a frame for receiving a truck which supplies ballast to a dispensing hopper at one end of the frame. A fluid system provides the locomotion and controls for the dispensing hopper. A turntable expedites conversion of the machine between road and rail use.

Claims

1. A self-propelled ballast dispensing machine comprising:

a frame;

a pair of wheels adjacent each end of said frame adapted for mobility on a pair of tracks;

a hopper means at one end of said frame for receiving and dispensing ballast onto a track bed;

said hopper means including a front wall extending substantially up from said frame but less than the height of the bed of a dump truck, a rear wall and a pair of said walls extending from said frame at least the height of said front wall;

means on each of said side walls and adjacent said front wall for increasing the distance of separation of the top portion of said side walls adjacent said front wall to accommodate the bed of the dump truck as it pivots into said hopper means;

said frame being sufficiently long to carry said dump truck on said frame for supplying ballast to said hopper means; and

drive means on said frame for propelling said machine on said tracks.

2. The self-propelled ballast dispensing machine according to claim 1 wherein said distance separation increasing means includes a movable wall portion pivotably connected at its bottom to said side wall with the tops of said movable wall portions pivotably away from each other.

3. The self-propelled ballast dispensing machine according to claim 1 including ramp means pivotally connected at the other end of said frame for permitting trucks to be driven onto said frame and resilient means between said ramp means and said body for maintaining the non-pivotal end of said ramp means above the ground when unloaded and allowing the non-pivotal end of said ramp means to engage the ground when loaded.

4. The self-propelled ballast dispensing machine according to claim 1 including a fluid control system;

and

said hopper means includes a fluid motor means connected to said fluid control system for controlling the amount of ballast dispensed by said hopper means.

5. The self-propelled ballast dispensing machine according to claim 4 wherein said hopper means includes a dispensing outlet extending substantially the width of said frame, a pair of doors slidably mounted across said dispensing outlet, and said fluid motor means includes a pair of fluid cylinders connected to a respective door to control the position of a respective door relative to said dispensing outlet to control the amount of ballast dispensed.

6. The self-propelled ballast dispensing machine according to claim 1 wherein said frame includes a flatbed portion to which said wheels and hopper means are mounted and a gooseneck portion extending above and forward the one end of said flatbed portion to which said hopper is mounted;

and further including an operator'"'"'s station on said gooseneck portion.

7. The self-propelled ballast dispensing machine according to claim 6 wherein said operator'"'"'s station includes a power source and fluid transmission driven by said power source;

and said drive means includes drive train means interconnecting said fluid transmission and a pair of wheels at the hopper end of the machine.

8. The self-propelled ballast dispensing machine according to claim 6 further including a pin means extending down from said gooseneck portion for connection to a fifth wheel of a truck tractor;

and means connected to said frame for raising and lowering said frame at the gooseneck portion to allow connection and disconnection of said frame to said truck tractor.

9. A self-propelled ballast dispensing machine according to claim 8 further including a turntable means secured to said flatbed portion of said frame at substantially the center of gravity of said machine for facilitating rotation of said frame relative to a track when supported on said track.

10. A self-propelled ballast dispensing machine according to claim 9 wherein said turntable means extends down from said frame less than the wheels so as not to engage the tracks.

11. A self-propelled ballast dispensing machine according to claim 8 further including a means on the end of said flatbed portion of said frame for receiving a pair of wheels for off-track travel.

12. A self-propelled ballast dispensing machine comprising:

a frame;

a pair of wheels adjacent each end of said frame adapted for mobility on a pair of tracks;

a hopper means at a first end of said frame for receiving and dispensing ballast onto a track bed;

means at said first end for connecting said frame to a fifth wheel of a truck tractor;

means at a second end of said frame for receiving a pair of wheels for off-track travel;

vertical means at said first end adjacent the outlet of said hopper means vertically movable relative to said frame for raising said frame above the ground to allow connection and disconnection of said frame and said truck tractor;

horizontal means connected to said vertical means and extend transverse thereto for spreading dispensed ballast when said vertical means lowers said horizontal means to said pair of tracks;

said frame being sufficiently long to carry a land vehicle on said frame for supplying ballast to said hopper means; and

drive means on said frame for propelling said machine on a pair of tracks.

13. The self-propelled ballast dispensing machine according to claim 12 wherein said frame includes a flatbed portion to which said wheels and hopper means are mounted and a gooseneck portion extending above and forward the one end of said flatbed portion to which said hopper is mounted;

and said fifth wheel connecting means is on said gooseneck portion.

14. The self-propelled ballast dispensing machine according to claim 13 further including an operator'"'"'s station on said goosebeck portion.
