Description: |
| Abstract:
This invention relates to improvements in variable-speed friction-gearing; and the object of the invention is to provide a mechanism in which the adjustment of the friction power-transmitter relative to the driving or driven elements to vary the speed of the latter will be effected practically automatically.
Claim:
In a device for changing speed, two parallel, rotatable wheels or disks, a friction-roller supported between and arranged to engage both said disks to transmit motion from one to the other, and means for adjusting the plane of rotation of said friction-roller angularly to its normal tangent position at its point of contact to cause said roller to traverse said wheels or disks in opposite directions toward or from their centers. |
