Claim 1
Independent Claim
155 words
A DRIVING DEVICE FOR MACHINES, COMPRISING: A POWER SOURCE; AN INFINITELY VARIABLE TRANSMISSION DRIVEN BY SAID POWER SOURCE; AN OUTPUT SHAFT; A HYDRAULICALLY OPERABLE FRICTION CLUTCH FOR CONNECTING SAID INFINITELY VARIABLE TRANSMISSION TO SAID OUTPUT SHAFT; HYDRAULICALLY OPERABLE ACTUATING MEANS FOR CHANGING THE RATIO OF SAID INFINITELY VARIABLE TRANSMISSION; A SOURCE OF FLUID PRESSURE; A CONTROL MEMBER SELECTIVELY MOVEABLE THROUGH A PREDETERMINED RANGE OF MOVEMENT; A FIRST VALVE OPERABLE BY SAID CONTROL MEMBER BY MOVEMENT THEREOF THROUGH AN INITIAL PORTION OF ITS RANGE OF MOVEMENT FOR DIRECTING GRADUALLY INCREASING FLUID PRESSURE FROM SAID SOURCE TO SAID FRICTION CLUTCH WHEREBY SAID CLUTCH IS GRADUALLY ENGAGED; AND A SECOND VALVE OPERABLE BY SAID CONTROL MEMBER BY MOVEMENT THEREOF THROUGH A LATER PORTION OF ITS RANGE OF MOVEMENT FOR DIRECTING FLUID PRESSURE FROM SAID SOURCE TO SAID ACTUATING MEANS FOR SAID INFINITELY VARIABLE TRANSMISSION TO THEREBY VARY THE DRIVE RATIO FROM SAID POWER SOURCE TO SAID OUTPUT SHAFT.
