Abstract
Abstract A throttle control device for use with a spring-return throttle wherein a rotatable sleeve on a handlebar must be rotated to advance the throttle, the throttle control device including a clamping arrangement receivable over the rotatable sleeve to be just forward of a handgrip normally received over the sleeve, the clamping arrangement having a tab that engages conventional equipment to prevent rotation of the clamping means, and including a lever operated cam for clamping the sleeve to hold the throttle in a pre-set position, the clamping arrangement being held in position by the handgrip.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A throttle control device, for a throttle apparatus including a handlebar and throttle operating means mounted on said handlebar, said throttle operating means including a sleeve rotatably mounted on said handlebar, said sleeve being adapted for receiving a handgrip thereover, and a housing fixed to said handlebar adjacent to said sleeve, said control device comprising clamping means for selectively holding said throttle operating means in a predetermined position, characterized in that said clamping means includes a disk defining an aperture for receiving said sleeve, said disk being positionable between said handgrip and said housing with said handgrip substantially contiguous to said disk, anchoring means for preventing rotation of said disk with respect to said housing including a tab fixed to said disk and engageable with said housing, said disk including a plurality of sections, means for urging said plurality of sections away from one another to enlarge said aperture and allow free rotation of said sleeve with respect to said disk, and constricting means for urging said plurality of sections towards one another to constrict said aperture and restrict rotation of said sleeve.
Claim 2
Dependent Claim
183 words
A throttle control device, for a throttle apparatus including a handlebar and throttle operating means mounted on said handlebar, said throttle operating means including a sleeve rotatably mounted on said handlebar, said sleeve being adapted for receiving a handgrip thereover, and a housing fixed to said handlebar adjacent to said sleeve, said control device comprising clamping means for selectively holding said throttle operating means in a predetermined position, characterized in that said clamping means includes a disk defining an aperture for receiving said sleeve, said disk being positionable between said handgrip and said housing with said handgrip substantially contiguous to said disk, anchoring means for preventing rotation of said disk with respect to said housing including a tab fixed to said disk and engageable with said housing, said disk including a plurality of sections, means for urging said plurality of sections away from one another to enlarge said aperture and allow free rotation of said sleeve with respect to said disk, and constricting means for urging said plurality of sections towards one another to constrict said aperture and restrict rotation of said sleeve.
Claim 3
Dependent Claim
39 words
A throttle control device as claimed in claim 1, and wherein said housing includes at least one fitting extending therefrom, characterized in that said tab is engageable with said at least one fitting for preventing rotation of said disk.

Claim 6
Dependent Claim
49 words
A throttle control device as claimed in claim 4, and further including a spring between said ears for urging said ears away from each other, a stud extending through said ears, said cam means being carried on one end of said stud, and a lever for operating said cam.
Claim 7
Dependent Claim
30 words
A throttle control device as claimed in claim 5, said at least one fitting comprising a pair of fittings spaced apart, said tab being receivable between said pair of fittings.
