Abstract
Abstract A two-speed motion transmitting mechanism is disclosed in which an input shaft has an input sprocket and the inner portion of a centrifugal clutch mounted thereon. The input sprocket is connected by a first endless chain to a sprocket mounted on an overrunning clutch which, in turn, is mounted on an auxiliary shaft. A second endless chain connects a sprocket mounted on the outer portion of said centrifugal clutch, which, in turn, has an output shaft extending centrally therefrom. Initially, the drive from the input shaft is effected through the first and second chain and the outer portion of the centrifugal clutch to the output shaft. After a predetermined speed is reached, the centrifugal clutch engages and the drive from the input shaft is effected directly through the centrifugal clutch to the output shaft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
A multi-speed motion transmitting mechanism comprising an input member and an output member mounted on a common axis, a centrifugal clutch having two rotatable members, one of said members connected to said output member for rotation therewith and the other of said members connected to said input member for rotation therewith, an auxiliary member spaced from said axis having an overrunning clutch thereon, means connecting said input member to said auxiliary member through said overrunning clutch, means connecting said auxiliary member to said one of said centrifugal clutch members to drive said output member through said overrunning clutch and said auxiliary member when the centrifugal clutch is disengaged, said centrifugal clutch operable to connect the output member directly to the input member for rotation at the same speed as the input member when said centrifugal clutch is engaged.
Claim 2
Dependent Claim
138 words
A multi-speed motion transmitting mechanism comprising an input member and an output member mounted on a common axis, a centrifugal clutch having two rotatable members, one of said members connected to said output member for rotation therewith and the other of said members connected to said input member for rotation therewith, an auxiliary member spaced from said axis having an overrunning clutch thereon, means connecting said input member to said auxiliary member through said overrunning clutch, means connecting said auxiliary member to said one of said centrifugal clutch members to drive said output member through said overrunning clutch and said auxiliary member when the centrifugal clutch is disengaged, said centrifugal clutch operable to connect the output member directly to the input member for rotation at the same speed as the input member when said centrifugal clutch is engaged.
Claim 3
Dependent Claim
150 words
A multi-speed motion transmitting mechanism comprising an input member and an output member mounted on a common axis, a centrifugal clutch having two rotatable members, one of said members connected to said output member for rotation therewith and the other of said members connected to said input member for rotation therewith, an auxiliary member spaced from said axis having an overrunning clutch thereon, an endless member connecting said input member to said auxiliary member through said overrunning clutch, an endless member connecting said auxiliary member to said one of said centrifugal clutch members to drive said output member through said overrunning clutch and said auxiliary member at a different speed than said input member when the centrifugal clutch is disengaged, said centrifugal clutch operable to connect the output member directly to the input member for rotation at the same speed as the input member when said centrifugal clutch is engaged.
Claim 4
Dependent Claim
150 words
A multi-speed motion transmitting mechanism comprising an input member and an output member mounted on a common axis, a centrifugal clutch having two rotatable members, one of said members connected to said output member for rotation therewith and the other of said members connected to said input member for rotation therewith, an auxiliary member spaced from said axis having an overrunning clutch thereon, an endless member connecting said input member to said auxiliary member through said overrunning clutch, an endless member connecting said auxiliary member to said one of said centrifugal clutch members to drive said output member through said overrunning clutch and said auxiliary member at a different speed than said input member when the centrifugal clutch is disengaged, said centrifugal clutch operable to connect the output member directly to the input member for rotation at the same speed as the input member when said centrifugal clutch is engaged.
Claim 5
Dependent Claim
197 words
A multi-speed motion transmitting mechanism comprising an input member and an output member mounted on a common axis, a centrifugal clutch having two rotatable members, one of said members connected to said output member for rotation therewith and the other of said members connected to said input member for rotation therewith, an auxiliary member spaced from said axis having an overrunning clutch thereon, means including a chain and sprockets mounted on said input member and said overrunning clutch, respectively, to define a first drive train connecting said input member to said auxiliary member through said overrunning clutch, means including a chain and sprockets mounted on said auxiliary shaft and said one centrifugal clutch member, respectively, to define a second drive train connecting said auxiliary member to said one of said centrifugal clutch members, said first and second drive trains arranged to drive said output member through said overrunning clutch and said auxiliary member at a different speed than said input member when the centrifugal clutch is disengaged, said centrifugal clutch operable to connect the output member directly to the inPut member for rotation at the same speed as the input member when said centrifugal clutch is engaged.
Claim 6
Dependent Claim
