Steplessly controlled differential reducer coupling

Claim 1

A STEPLESSLY REGULATED DIFFERENTIAL REDUCER COUPLING COMPRISING A NONROTATING SURFACE OF ROLLING CONTACT HAVING CREASED, AND A ROLLING WHEEL TO BE BROUGHT INTO CONTACT WITH SAID SURFACE, A DRIVING SHAFT WITH RESPECT TO WHICH SAID WHEEL IS FREELY ROTATABLE, A DRIVEN SHAFT OPERATIVELY CONNECTED WITH THE SAID WHEEL FOR ROTATION THEREWITH, ECCENTRIC MEANS CARRIED BY SAID DRIVING SHAFT AND SUPPORTING SAID ROLLING WHEEL FOR FREE ROTATION WITH RESPECT TO SAID DRIVING SHAFT, FIRST ADJUSTING MEANS OPERATIVELY CONNECTED TO SAID ECCENTRIC MEANS FOR TRANSMITTING FROM SAID DRIVING SHAFT TO SAID ROLLING WHEEL AN ECCENTRIC MOVEMENT OF CONTROLLABLE MAGNITUDE IN ORDER TO BRING THE ROLLING WHEEL INTO A ROLLING MOVEMENT ALONG THE SURFACE OF ROLLING CONTACT, AND SECOND ADJUSTING MEANS OPERATIVELY CONNECTED WITH SAID SURFACE OF ROLLING CONTACT FOR ADJUSTING THE LATTER TO A DIAMETER CORRESPONDING TO THE MAGNITUDE OF ECCENTRIC MOVEMENT OF SAID ROLLING WHEEL, SAID SURFACE OF ROLLING CONTACT BEING FORMED BY TWO RINGS, COAXIAL WITH SAID DRIVING SHAFT AND OF EQUAL DIAMETER, WHICH BETWEEN THEMSELVES FORM A WEDGE-SHAPED GROOVE DEFINED BY SAID SURFACE OF ROLLING CONTACT, SAID RINGS, HAVING THREADS AT THEIR OUTER PERIPHERIES, A STATIONARY FRAME SURROUNDING AND BEING IN THREADED ENGAGEMENT WITH SAID THREADED PERIPHERIES OF SAID RINGS FOR SUPPORTING SAID RINGS FOR MOVEMENT TOWARD AND AWAY FROM EACH OTHER IN RESPONSE TO TURNING THEREOF WITH RESPECT TO SAID FRAME, SAID SECOND ADJUSTING MEANS BEING OPERATIVELY CONNECTED WITH SAID RINGS FOR TURNING THEM WITH RESPECT TO SAID FRAME SO AS TO MOVE AND RINGS AXIALLY IN RELATION TO THE DRIVING SHAFT TOWARD OR AWAY FROM EACH OTHER.
