Abstract
Abstract A cover plate attachable to a motorcycle to cover transmission structure, and an annular bore surface on the cover plate defining an axis coincident with the motorcycle engine drive shaft axis comprising a sprocket shaft axially spaced from the drive shaft; a compensating nut on the sprocket shaft; an output pulley drive shaft coaxially aligned and coupled to the sprocket shaft and the compensating nut, and an output pulley on the output pulley drive shaft for transmitting drive to a supercharger for the engine.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
In combination with a cover plate attached to a motorcycle to cover transmission structure, and an annular bore on the cover plate defining an axis, said motorcycle including an engine drive shaft having an axis, said cover plate axis being coincident with the motorcycle engine drive shaft axis, the combination comprising: a) a sprocket shaft axially spaced from said drive shaft, b) a compensating nut on the sprocket shaft, c) an output pulley drive shaft coaxially aligned and coupled to said sprocket shaft and said compensating nut, and an output pulley on said output pulley drive shaft for transmitting drive to a supercharger for said engine, and d) mounting means extending about the output pulley drive shaft, and received adjacent said annular bore on the cover plate to center the output pulley drive shaft in spaced relation to the engine drive shaft.
Claim 2
Dependent Claim
142 words
In combination with a cover plate attached to a motorcycle to cover transmission structure, and an annular bore on the cover plate defining an axis, said motorcycle including an engine drive shaft having an axis, said cover plate axis being coincident with the motorcycle engine drive shaft axis, the combination comprising: a) a sprocket shaft axially spaced from said drive shaft, b) a compensating nut on the sprocket shaft, c) an output pulley drive shaft coaxially aligned and coupled to said sprocket shaft and said compensating nut, and an output pulley on said output pulley drive shaft for transmitting drive to a supercharger for said engine, and d) mounting means extending about the output pulley drive shaft, and received adjacent said annular bore on the cover plate to center the output pulley drive shaft in spaced relation to the engine drive shaft.
Claim 3
Dependent Claim
35 words
The combination of claim 1 wherein said compensating nut and said output pulley drive shaft have telescopically interfitting parts for transmitting rotation from the output pulley drive shaft to said sprocket shaft via said nut.
Claim 4
Dependent Claim
37 words

Claim 5
Dependent Claim
36 words
The combination of claim 1 wherein said sprocket shaft has an end portion that is externally threaded, and said nut is received on and over said end portion and has threaded engagement with said end portion.
Claim 6
Dependent Claim
36 words
The combination of claim 3 wherein said sprocket shaft has an end portion that is externally threaded, and said nut is received on and over said end portion, and has threaded engagement with said end portion.
Claim 7
Dependent Claim
43 words
The combination of claim 4 wherein said nut includes a flange, there being a recess in said flange in axial alignment with said sprocket shaft, and there being a lug on said output pulley drive shaft, the lug axially received in said recess.
Claim 8
Dependent Claim
17 words
The combination of claim 1 wherein said mounting means includes a flange received in said annular bore.
Claim 9
Dependent Claim
25 words
The combination of claim 1 including said cover plate attached to said mounting means, and relative to which the output pulley drive shaft is rotatable.
