(under the class definition) Subject matter wherein means are provided to change the rotational velocity of the output body divided by the rotational velocity of the input body, said means having mechanism to sense a condition or change of condition in the environment of the friction gear transmission; and, in response to such sensing, effect said change of rotational velocity. [figure] [caption] The Patent illustrates that as the torque increases, however, the spring 60 permits the cammed surfaces 18 to slip down somewhat under the pin 19. This has caused idler 15 to be pushed down and this downward force is counterbalanced by the compression of the spring 60. As the load increases resulting in added torque, the increased slippage in the driving elements above described results in a relatively slower movement of the turntable with respect to the motor so that the turntable speed tends to drop from the constant desired speed. This is compensated for immediately by the shifting of the idler 15 down the slope of cone 14 to a different driving ratio producing a greater relative speed between the turntable and motor in order to maintain the constant turntable speed.
