Coupling with air cooled friction discs

Claim 1

A FRICTION ASSEMBLY COMPRISING; A SET OF INNER DISCS SURROUNDING AND DISTRIBUTED ALONG A COMMON AXIS AND A SET OF OUTER DISCS ALSO SURROUNDING AND DISTRIBUTED ALONG SAID AXIS, SAID OUTER DISCS RADIALLY OVERLAPPING AND EXTENDING OUTWARDLY BEYOND SAID INNER DISCS, MEANS MOUNTING BOTH SETS OF DISCS FOR MOVEMENT ALONG SAID AXIS AND AT LEAST ONE OF SAID SETS OF DISCS FOR ROTATION ABOUT SAID AXIS, THE NUMERICAL RATIO BETWEEN AT LEAST SOME OF SAID INNER DISCS AND THE OUTER DISCS COOPERATING THEREWITH BEING TWO OUTER DISCS FOR EACH INNER DISC ARRANGED RESPECTIVELY ON OPPOSED SIDES OF AND ADAPTED TO FRICTIONALLY ENGAGE EACH INNER DISC SO THAT A PAIR OF OUTER DISCS ARE PROVIDED FOR EACH OF SAID INNER DISCS TO WHICH SAID NUMERICAL RATIO APPLIES, SAID PAIRS OF OUTER DISCS BEING AXIALLY SPACED FROM EACH OTHER SO THAT BETWEEN EACH PAIR OF SUCCESSIVE INNER DISCS TO WHICH SAID NUMERICAL RATIO APPLIES THERE ARE TWO AXIALLY SPACED OUTER DISCS, MEANS COOPERATING WITH SAID OUTER DISCS FOR PRESSING THE LATTER AGAINST SAID INNER DISCS AND FOR RELEASING THE PRESSURE OF SAID OUTER DISCS AGAINST SAID INNER DISCS, AND BLOWER MEANS OPERATIVELY CONNECTED TO THAT ONE OF SAID SETS OF DISCS WHICH ROTATES ABOUT SAID AXIS FOR ROTATION THEREWITH, SAID BLOWER MEANS INCLUDING A PLURALITY OF BLOWER WHEELS, AND THE TWO AXIALLY SPACED OUTER DISCS SITUATED BETWEEN EACH OF SAID PAIRS OF SUCCESSIVE INNER DISCS DEFINING BETWEEN THEMSELVES A SPACE WHICH RECEIVES ONE OF SAID BLOWER WHEELS, SAID BLOWER MEANS DIRECTING AIR FIRST AXIALLY AND THEN RADIALLY WITH RESPECT TO SAID AXIS, AND EACH OF SAID BLOWER WHEELS HAVING AN AXIALLY EXTENDING SUCTION PASSAGE AND A SUBSTANTIALLY RADIALLY EXTENDING DISCHARGE PASSAGE, SAID MEANS FOR MOUNTING BOTH SETS OF DISCS FOR MOVEMENT ALONG SAID AXIS INCLUDING FOR SAID OUTER DISCS A PLURALITY OF ELONGATED SUPPORTING ASSEMBLIES EXTENDING PARALLEL TO SAID COMMON AXIS THROUGH SAID OUTER DISCS AND BEING UNIFORMLY DISTRIBUTED ABOUT SAID COMMON AXIS TO LEAVE FREE ANGULAR PORTIONS OF SAID OUTER DISCS SITUATED BETWEEN SAID ELONGATED SUPPORTING ASSEMBLIES.
