Abstract:
A device for attachment to fluid levitated object for stopping and guiding movement along a ground surface thereunder, comprising:(a) a supporting frame, (b) a brake, (c) a brake attachment frame mounting said brake on said supporting frame and in cooperation with said ground surface so as to afford readily stoppable movement characteristics to the device, (d) a brake variable-yieldable bias means between said brake attachment frame and said supporting frame, producing variable force therebetween to yieldably urge said brake into anti-slip rubbing engagement with said ground surface, (e) a guide wheel, (f) a guide wheel attachment means mounting said guide wheel on said brake attachment frame for rotation about a horizontal axis and cooperation with the aforesaid ground surface so as to afford readily guidable non-side-slip movement characteristics to the device, (g) a compressive separating means between said brake attachment frame and said guide wheel attachment means, so when said brake variable-yieldable bias means force is low, said guide wheel only contacts said ground surface; and as said brake variable-yieldable bias means force is high, said brake also contacts said ground surface.
