Description: |
| Abstract:
In carrying out my invent ion I combine with the front axle pivoted to the carriage-body so as to turn in a horizontal plane and with the rear or driving axle a mechanism for clutching the wheels of such driving-axle to it, and clutching them from it during the turning of the front axle in either direction, the object of my invention being to enable the carriage to turn quick or sharp curves to advantage, and one of the rear wheels, while remaining on the curves, to revolve independently of the driving-axle, such wheel, while the carriage may be running in a straight path, being so clutched to the axle as to be revolved by it. The wheel so unclutched is that which, while the carriage may be on the curve, may be on the outside or longer rail or wheel-path. By allowing it to run independently of the other or fellow wheel and the driving-axle, while the latter are in conjunction and both wheels are on a curved track, the inner wheel will not slip on the track, but both wheels will readily conform themselves to the length of curve each has to pass over.
Claim:
The combination of the two clutches and their operative mechanism, substantially as described, or the equivalent thereof, with the wheels and the two axles, applied together and to the carriage- body, essentially as hereinbefore explained, the purpose of the clutches and their operative mechanism. |
