Abstract
Improvements in the controls of the racing or progressive speed devices, characterized essentially by the fact of having a drive shaft, two conical plates, one fixed and the other displaceable, or the two displaceable, which by joining or separating them increase the diameters or they diminish, achieving progressive diameters for trapezoidal belts, which drag another axis in which they are mounted equal plates, in which while the motor increases the diameter the driven decreases it, or vice versa, achieving progressivity by this double effect; or it attacks a driven with fixed pulley of fixed diameter, regulating the tension of the belt, of the differences in diameter of the driven shaft plates, a pulley with tensioner, working on the face or inverse of the belt, which loosening The tensioner can serve as a clutch achieving progressivity by simple effect and moving the conical plates on bearing sleeves, free on the axis where the belt rests in the maximum opening of the plates.
