Abstract
Abstract An end member positioned against the end of a handle bar is engageable with a throttle sleeve rotatably mounted upon the handle bar. The end member also includes an expansion member residing within the handle. A manually movable expander selectively moves the expansion member into frictional engagement with the inside surface of the handle bar for retaining the throttle sleeve at rotatably selective positions relative the handle bar.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
A throttle setting device for use in combination with a vehicle, which vehicle includes, a cylindrical tubular handle bar having an inside surface and an end, a tubular throttle sleeve having an outside surface coaxially rotatably mounted upon said handle bar, and a hand grip coaxially sheathing said throttle sleeve and rotatable therewith, and for retaining said throttle sleeve at rotatably selective positions relative said handle bar, said throttle control device comprising: a. an end member positioned proximate the end of said handle bar; b. engagement means carried by said end member for interlocking said end member with said throttle sleeve; and c. retention means carried by said end member for selectively engaging said handle bar and stabilizing said end member against rotation.
Claim 2
Dependent Claim
123 words
A throttle setting device for use in combination with a vehicle, which vehicle includes, a cylindrical tubular handle bar having an inside surface and an end, a tubular throttle sleeve having an outside surface coaxially rotatably mounted upon said handle bar, and a hand grip coaxially sheathing said throttle sleeve and rotatable therewith, and for retaining said throttle sleeve at rotatably selective positions relative said handle bar, said throttle control device comprising: a. an end member positioned proximate the end of said handle bar; b. engagement means carried by said end member for interlocking said end member with said throttle sleeve; and c. retention means carried by said end member for selectively engaging said handle bar and stabilizing said end member against rotation.
Claim 3
Dependent Claim
24 words
The throttle setting device of claim 1, wherein said engagement means includes means for receiving and gripping to outside surface of said throttle sleeve.
Claim 4
Dependent Claim
34 words
The throttle setting device of claim 1, wherein said engagement means includes: a. a recess formed in said throttle sleeve; and b. a tab projecting from said end member and received within said recess.
Claim 5
Dependent Claim
44 words
The throttle setting device of claim 1 wherein said retention means includes: a. an expansion member extending from said end member within said handle bar; and b. an expander for selectively expanding said expansion member outwardly against the inside surface of said handle bar.
Claim 6
Dependent Claim
106 words
The throttle setting device of claim 4, wherein: a. said expansion member includes a tubular projection having a free end and being severed longitudinally from said free end to form deflectable fingers; and b. said expander includes, i. a generally conical element having a convergent end directed toward said end member, and ii. handle means for alternately moving said expander in a first direction toward said end element for deflecting said fingers outwardly into frictional engagement with the inner surface of said handle bar and a second direction away from said end member for relaxation of said fingers from the inner surface of said handle bar.
Claim 7
Dependent Claim
57 words
The throttle setting device of claim 5, wherein said handle means includes: a. guide means extending through said end element; b. a stem slidable extending through said guide means and having, i. a first end affixed to said expander, and ii. a second end; and c. a hand knob affixed to the second end of said stem.
Claim 8
Dependent Claim
25 words
The throttle setting device of claim 5, wherein said fingers have a relatively smooth, low-friction surface for contacting the inside surface of said handle bar.
