Japanese Patent JPS5225607
Kind Code:
B2
Abstract:
A rolling stock accelerator is disclosed which will start a railway car or similar vehicle moving from a standing start, and/or accelerate an already moving car at low speed. A number of screw drums having helical fins mounted thereon are disposed axially in parallel with the rails of the track, with a mechanism for controlling their operation, all mounted upon a base. In response to an external signal, each of the screw drums is rotated axially, causing the helical fins to engage the flanges of the car wheels, thereby moving the car forwad or accelerating it by means of the rising surface of the rotating fin impelling the wheel forward.
