Abstract

Abstract Disclosed herein is a throttle control for an engine including a housing supporting a control lever for rotation relative to a neutral position, a throttle lever movably mounted on the housing and adapted to actuate the engine throttle, a throttle drive member including a drive pin and mounted for rotation in response to movement of the control lever from the neutral position, and a cam member connected between the throttle lever and the throttle drive member. The cam member includes a cam track receiving the drive pin and having a shape effective to displace the cam member relative to the throttle drive member, transversely relative to the rotational axis of the throttle drive member, so as to move the throttle lever in response to rotation of the throttle drive member. In one embodiment, the control further includes a shift lever movably mounted on the housing and adapted to actuate the engine clutch and a shift drive member drivingly connected to the shift lever for actuating the engine clutch in response to movement of the control lever from the neutral position. The cam track is arranged so that the cam member, and thus the throttle lever, remains in an engine idle position during initial movement of the control lever from the neutral position to actuate the engine clutch and so that further movement of the control lever from the neutral position causes translatory movement of the cam member to advance the engine throttle.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 205 words
A throttle control for an engine having a throttle, said control comprising a housing, a shaft member supported within said housing for rotation relative to said housing, a control lever connected to said shaft member for common rotation therewith relative to a neutral position, a throttle lever movably mounted on said housing and adapted to actuate the engine throttle in response to movement of said throttle lever, a throttle drive member including a drive pin and mounted on said shaft member for common rotation therewith in response to movement of said control lever from the neutral position, a cam member carried by said throttle drive member and connected between said throttle lever and said throttle drive member, said cam member including a cam track receiving said drive pin and having a shape effective to displace said cam member relative to said shaft member and to said throttle drive member to move said throttle lever in response to rotation of said throttle drive member, and guide means on said cam member and on said throttle drive member for guiding translatory movement of said cam member relative to the rotational axis of said shaft member in response to movement of said drive pin in said cam track.
Claim 2
Dependent Claim 205 words
A throttle control for an engine having a throttle, said control comprising a housing, a shaft member supported within said housing for rotation relative to said housing, a control lever connected to said shaft member for common rotation therewith relative to a neutral position, a throttle lever movably mounted on said housing and adapted to actuate the engine throttle in response to movement of said throttle lever, a throttle drive member including a drive pin and mounted on said shaft member for common rotation therewith in response to movement of said control lever from the neutral position, a cam member carried by said throttle drive member and connected between said throttle lever and said throttle drive member, said cam member including a cam track receiving said drive pin and having a shape effective to displace said cam member relative to said shaft member and to said throttle drive member to move said throttle lever in response to rotation of said throttle drive member, and guide means on said cam member and on said throttle drive member for guiding translatory movement of said cam member relative to the rotational axis of said shaft member in response to movement of said drive pin in said cam track.
Claim 3
Dependent Claim 46 words
A throttle control according to claim 1 wherein said throttle lever is mounted for pivotal movement about an axis fixed relative to said housing, and said cam member is connected to said throttle lever by a pivot spaced from the pivotal mounting of said throttle lever.
Claim 4
Dependent Claim 49 words
A throttle control according to claim 1 wherein said cam track includes a central portion extending at a uniform radius from the rotational axis of said throttle drive member and end portions extending from said central portion at increasing distances from the rotational axis of said throttle drive member.
Claim 5
Dependent Claim 50 words
A throttle control according to claim 1 wherein said guide means includes a bushing having a part which surrounds a portion of said throttle drive member and has an outer bearing surface and wherein said cam member includes an oblong slot having opposed walls which slidably engage said bearing surface.
Claim 6
Dependent Claim 29 words
A throttle control according to claim 4 wherein said bushing includes another part carried by said housing and a central bore rotatably receiving one end of said shaft member.
