Abstract

Abstract A structurally encapsulated assembly is disclosed which provides override for a speed control unit so that throttle advance by the vehicle operator, once set speed is reached, has no effect on the setting provided for the engine by the speed control unit. The encapsulated assembly is attached, at its one end to a cable connecting means extending to the speed control unit, at its other end to the pedal operated linkage and, therefore, is in series between them.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 218 words
An antioverride mechanism for a speed control unit that is responsive to the road speed of a vehicle having a throttle pedal linkage and a carburetor with a throttle arm comprising; (a) a cable having a flexible sheath and a flexible core within said sheath and freely slidable relative thereto, said sheath having one end adapted to be secured to said speed control unit, said core having one end adapted to be secured to the speed control unit and movable thereby relative to said sheath; (b) a tubular housing having a first end secured to the other end of said sheath and being adapted to receive said core; (c) a slidable member positioned within said tubular housing for sliding movement relative thereto, the other end of said core being secured to said slidable member; (d) resilient means for resiliently biasing said slidable member away from said first end of said tubular housing, the resilient force imposed by said resilient means being insufficient to restrain movement of said core by said speed control unit relative to said sheath; (e) ball stud means for pivotally securing said slidable member to said throttle arm; and (f) linkage means for securing said housing to said throttle pedal linkage whereby said housing will move in response to movement of said throttle pedal linkage.
Claim 2
Dependent Claim 218 words
An antioverride mechanism for a speed control unit that is responsive to the road speed of a vehicle having a throttle pedal linkage and a carburetor with a throttle arm comprising; (a) a cable having a flexible sheath and a flexible core within said sheath and freely slidable relative thereto, said sheath having one end adapted to be secured to said speed control unit, said core having one end adapted to be secured to the speed control unit and movable thereby relative to said sheath; (b) a tubular housing having a first end secured to the other end of said sheath and being adapted to receive said core; (c) a slidable member positioned within said tubular housing for sliding movement relative thereto, the other end of said core being secured to said slidable member; (d) resilient means for resiliently biasing said slidable member away from said first end of said tubular housing, the resilient force imposed by said resilient means being insufficient to restrain movement of said core by said speed control unit relative to said sheath; (e) ball stud means for pivotally securing said slidable member to said throttle arm; and (f) linkage means for securing said housing to said throttle pedal linkage whereby said housing will move in response to movement of said throttle pedal linkage.
Claim 3
Dependent Claim 34 words
The antioverride mechanism of claim 1, wherein said ball stud means includes a longitudinally extending slot in said tubular housing and a ball stud secured to said slidable member and extending through said slot.
