Claim 6

A clutch-coupling combination comprising: a drive hub member; a driven hub member; an inner drum member; means connecting said inner drum member to said driven hub member; a cylindrical bearing surface on said drive hub member; a cylindrical bearing surface on said inner drum member rotatably received on said drive hub member cylindrical surface; a clutch sleeve fixed to said drive hub; said clutch sleeve being generally concentric to said inner drum and defining an annular space between said clutch sleeve and said inner drum; drive clutch discs on said clutch sleeve in said annular space; driven clutch discs on said inner drum in said space; said drive clutch discs having engaging means adapted to engage said driven clutch discs; means connecting said drive clutch discs to said drive hub; and means connecting said driven clutch discs to said inner drum; actuating means for forcing said drive clutch discs and said driven clutch discs into frictional engagement with each other whereby said drive hub and said inner drum are fixed together; said means connecting said driven hub and said inner drum together comprise internal teeth on said inner drum; a coupling spacer; external gear teeth on said coupling spacer engaging said internal teeth on sad inner drum; and and means connecting said coupling spacer to said driven hub.

Claim 7

A clutch-coupling combination comprising: a drive hub member; a driven hub member; an inner drum member; means connecting said inner drum member to said driven hub member; a cylindrical bearing surface on said drive hub member; a cylindrical bearing surface on said inner drum member rotatably received on said drive hub member cylindrical surface; a clutch sleeve fixed to said drive hub; said clutch sleeve being generally concentric to said inner drum and defining an annular space between said clutch sleeve and said inner drum; drive clutch discs on said clutch sleeve in said annular space; driven clutch discs on said inner drum in said space; said drive clutch discs having engaging means adapted to engage said driven clutch discs; means connecting said drive clutch discs to said drive hub; and means connecting said driven clutch discs to said inner drum; actuating means for forcing said drive clutch discs and said driven clutch discs into frictional engagement with each other whereby said drive hub and said inner drum are fixed together; said means connecting said driven hub and said inner drum together comprise internal teeth on said inner drum; a coupling spacer; external gear teeth on said coupling spacer engaging said internal teeth on sad inner drum; and and means connecting said coupling spacer to said driven hub.

Claim 8

The combination recited in claim 5 wherein said drive hub has: a radially outwardly extending flange fixed thereto; an annular cylinder attached to the outer periphery of said radially extending flange; an inwardly extending cylinder head fixed to said cylinder; said cylinder head being generally concentric to said drive hub; an internal cylindrical surface on said cylinder; said actuating means comprising an annular piston having an external cylindrical surface slidably engaging said internal cylindrical surface on said cylinder; and piston rod means attached to said piston and engaging said friction discs.

Claim 9

The combination recited in claim 5 wherein said means connecting said coupling spacer to said driven hub comprises: external teeth on said coupling spacer; and internal teeth in a member supported on said driven hub engaging said external teeth on said spacer drum.

Claim 10

The combination recited in claim 5 wherein said means connecting said innner drum to said driven hub comprises a coupling spacer having first external teeth and second external teeth thereon spaced from said first external teeth; first internal teeth on said inner drum engaging said first external teeth; second internal teeth on means on said driven hub engaging said second external teeth; and said first external teeth and said second external teeth having generally spherical flank surfaces.

Claim 11

The combination recited in claim 5 wherein said actuating means comprises: an axially extending piston rod on said drive hub; means on said piston rod engaging said clutch discs; a cylinder on said drive hub; said cylinder having an inwardly directed cylinder head; an annular piston slidably engaging said cylinder; said inwardly directed cylinder head; said piston and said cylinder defining an annular control space; and means to admit liquid to said annular control space whereby centrifugal force acting on said piston moves said piston to actuate said discs.

Claim 12

The combination recited in claim 9 wherein said inwardly directed cylinder head has bleed holes therein adjacent the outer periphery thereof whereby liquid may escape from said annular space.

Claim 13

The combination recited in claim 5 wherein two said cylindrical bearing surfaces are supported on said drive hub; said two said cylindrical bearing surfaces comprising firSt and said second bearing surfaces being axially spaced from each other; said inner drum has two spaced external cylindrical bearing surfaces engaging said first and said second bearing surfaces; and said teeth on said inner drum being disposed between said first bearing surfaces and said second bearing surfaces.

Claim 14

The combination recited in claim 11 wherein said means connecting said coupling spacer to said driven hub comprises: external teeth on said coupling spacer; and internal teeth on means on said driven hub engaging said external teeth.

Claim 15

The combination recited in claim 11 wherein: said clutch sleeve is fixed to said radially extending flange; said clutch sleeve extends axially from said radially extending flange and generally concentric to said cylindrical bearing surface; an inwardly directed end plate on the end of said clutch sleeve; and an axially extending bearing member on said inwardly directed end plate; and a second driven drum bearing surface being disposed on said axially extending bearing member.
