Abstract
Abstract A clutch disengaging and bypassing assembly including a shaft slidable between clutch engaged and clutch disengaged positions and carrying a floating coupling for coupling an input coupling sleeve rotated by an input driving shaft with the clutch, the floating coupling transmitting rotation of the input coupling sleeve to the clutch and the clutch being splined to the slidable shaft when the shaft is in the clutch engaged position and an input end of the shaft being splined to the input coupling sleeve, the floating coupling disengaging the clutch and a splined portion of the shaft disengaging the clutch when the shaft is in the clutch disengaged position such that the clutch is completely bypassed and disengaged from the drive train.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
233 words
An assembly for disengaging and bypassing a clutch assembly for transmitting rotation of an input shaft to an output shaft, the assembly comprising a rotatable, axially slidable shaft having input and output ends, and carrying first engaging means at said input end and second engaging means for coupling said slidable shaft with the clutch assembly; output coupling means coupling said output end of said slidable shaft to the output shaft; input coupling means rotatable with the input shaft carrying third engaging means for engaging said slidable shaft; floating coupling means carried by said slidable shaft for coupling said input coupling means with the clutch assembly; and means for selectively sliding said slidable shaft between a clutch engaged position and a clutch disengaged position, said second engaging means being coupled with said clutch assembly and said floating coupling means coupling said input coupling means with the clutch assembly when said slidable shaft is in said clutch engaged position, and said first engaging means carried by said slidable shaft engaging said third engaging means carried by said input coupling means, said floating coupling means disengaging the clutch assembly and said second engaging means carried by said slidable shaft disengaging the clutch assembly when said slidable shaft is in said disengaged position whereby the clutch assembly is bypassed when said slidable shaft is in said clutch disengaged position and does not rotate with said slidable shaft.
Claim 2
Dependent Claim
233 words
An assembly for disengaging and bypassing a clutch assembly for transmitting rotation of an input shaft to an output shaft, the assembly comprising a rotatable, axially slidable shaft having input and output ends, and carrying first engaging means at said input end and second engaging means for coupling said slidable shaft with the clutch assembly; output coupling means coupling said output end of said slidable shaft to the output shaft; input coupling means rotatable with the input shaft carrying third engaging means for engaging said slidable shaft; floating coupling means carried by said slidable shaft for coupling said input coupling means with the clutch assembly; and means for selectively sliding said slidable shaft between a clutch engaged position and a clutch disengaged position, said second engaging means being coupled with said clutch assembly and said floating coupling means coupling said input coupling means with the clutch assembly when said slidable shaft is in said clutch engaged position, and said first engaging means carried by said slidable shaft engaging said third engaging means carried by said input coupling means, said floating coupling means disengaging the clutch assembly and said second engaging means carried by said slidable shaft disengaging the clutch assembly when said slidable shaft is in said disengaged position whereby the clutch assembly is bypassed when said slidable shaft is in said clutch disengaged position and does not rotate with said slidable shaft.
Claim 3
Dependent Claim
33 words
An assembly as recited in claim 1 wherein said floating coupling means is a splined ring rotatably mounted on said slidable shaft and longitudinally fixed thereto for sliding movement with said slidable shaft.
Claim 4
Dependent Claim
29 words
An assembly as recited in claim 2 wherein said means for selectively sliding said slidable shaft includes a ring rotatably mounted on said slidable shaft and longitudinally fixed thereto.
Claim 5
Dependent Claim
32 words
An assembly as recited in claim 3 and further comprising means for selectively disengaging said output coupling means from the output shaft when said slidable shaft is in said clutch disengaged position.
Claim 6
Dependent Claim
32 words
An assembly as recited in claim 1 and furthEr comprising means for selectively disengaging said output coupling means from the output shaft when said slidable shaft is in said clutch disengaged position.
Claim 7
Dependent Claim
277 words
An assembly for transmitting rotation of an input shaft to an output shaft comprising a clutch assembly having a rotatable flywheel and clutch plate; a rotatable, axially slidable shaft extending centrally through said clutch assembly and having a splined input end, an output end and a splined portion for engaging said clutch plate; an output coupling engaging said output end of said slidable shaft and the output shaft to transmit rotation from said slidable shaft to the output shaft; an input coupling sleeve secured to the input shaft and rotatable therewith and having a first splined portion for engaging said splined input end of said slidable shaft and a second splined portion; a floating splined coupling rotatably mounted on said slidable shaft and longitudinally fixed thereto for sliding movement with said slidable shaft, said floating coupling engaging said second splined portion of said input coupling sleeve for selectively coupling said input coupling sleeve with said flywheel; and means for selectively sliding said slidable shaft between a clutch engaged position wherein said floating coupling couples said input coupling sleeve with said flywheel for rotation therewith and said splined portion of said slidable shaft engages said clutch plate and a clutch disengaged position wherein said splined input end of said slidable shaft engages said first splined portion of said input coupling sleeve, said floating coupling disengages said flywheel and said splined portion of said slidable shaft disengages said clutch plate whereby the clutch assembly is bypassed when said slidable shaft is in said clutch disengaged position with rotation of the input shaft transmitted to the output shaft through said input coupling sleeve, said slidable shaft and said output coupling.
Claim 8
Dependent Claim
277 words
An assembly for transmitting rotation of an input shaft to an output shaft comprising a clutch assembly having a rotatable flywheel and clutch plate; a rotatable, axially slidable shaft extending centrally through said clutch assembly and having a splined input end, an output end and a splined portion for engaging said clutch plate; an output coupling engaging said output end of said slidable shaft and the output shaft to transmit rotation from said slidable shaft to the output shaft; an input coupling sleeve secured to the input shaft and rotatable therewith and having a first splined portion for engaging said splined input end of said slidable shaft and a second splined portion; a floating splined coupling rotatably mounted on said slidable shaft and longitudinally fixed thereto for sliding movement with said slidable shaft, said floating coupling engaging said second splined portion of said input coupling sleeve for selectively coupling said input coupling sleeve with said flywheel; and means for selectively sliding said slidable shaft between a clutch engaged position wherein said floating coupling couples said input coupling sleeve with said flywheel for rotation therewith and said splined portion of said slidable shaft engages said clutch plate and a clutch disengaged position wherein said splined input end of said slidable shaft engages said first splined portion of said input coupling sleeve, said floating coupling disengages said flywheel and said splined portion of said slidable shaft disengages said clutch plate whereby the clutch assembly is bypassed when said slidable shaft is in said clutch disengaged position with rotation of the input shaft transmitted to the output shaft through said input coupling sleeve, said slidable shaft and said output coupling.
Claim 9
Dependent Claim
26 words
