Abstract
Abstract In order to prevent the slack of a core of an accelerator wire which otherwise may occur during the operation of an apparatus to maintain the vehicle in running at some desired speed, a guide is arranged along a portion of the core between an end of an outer casing of the accelerator wire from which the core extends outwardly and a member, fixed to a carburetor torsion shaft, at which the core is anchored.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
200 words
A carburetor control system for a motor vehicle including an apparatus to maintain the vehicle in running at some desired speed, the carburetor control system comprising: a torsion shaft for controlling an angular position of a throttle blade of a carburetor; a member, fixedly mounted to said torsion shaft; a throttle return spring for biasing said member in one rotational direction; an accelerator; an accelerator wire including an outer casing and a core extending through said outer casing, said outer casing having, at an end adjacent to said member, a switch stop spaced from said member and fixed to a fixed portion of the vehicle body by a bracket, said core having one end engaging said member and an opposite end operatively connected to said accelerator and arranged to transmit motion of said accelerator to said member against said throttle return spring; and means for holding said member at various angular positions thereof against the bias of said throttle return spring independently of the position of said accelerator in accordance with various running conditions of the vehicle; in which a stationary guide is arranged along the core of said accelerator wire which extends between said member and said switch stop.
Claim 2
Dependent Claim
200 words
A carburetor control system for a motor vehicle including an apparatus to maintain the vehicle in running at some desired speed, the carburetor control system comprising: a torsion shaft for controlling an angular position of a throttle blade of a carburetor; a member, fixedly mounted to said torsion shaft; a throttle return spring for biasing said member in one rotational direction; an accelerator; an accelerator wire including an outer casing and a core extending through said outer casing, said outer casing having, at an end adjacent to said member, a switch stop spaced from said member and fixed to a fixed portion of the vehicle body by a bracket, said core having one end engaging said member and an opposite end operatively connected to said accelerator and arranged to transmit motion of said accelerator to said member against said throttle return spring; and means for holding said member at various angular positions thereof against the bias of said throttle return spring independently of the position of said accelerator in accordance with various running conditions of the vehicle; in which a stationary guide is arranged along the core of said accelerator wire which extends between said member and said switch stop.
Claim 3
Dependent Claim
209 words
A carburetor control system for a motor vehicle including an apparatus to maintain the vehicle in running at some desired speed, the carburetor control system comprising: a torsion shaft for controlling an angular position of a throttle blade of a carburetor; a member fixedly mounted to said torsion shaft; a throttle return spring for biasing said member in one rotational direction; an accelerator; an accelerator wire including an outer casing and a core extending through said outer casing, said outer casing having, at an end adjacent to said member, a switch stop spaced from said member and fixed to a fixed portion of the vehicle body by a bracket, said core having one end engaging said member and an opposite end operatively connected to said accelerator and arranged to transmit motion of said accelerator to said member against said throttle return spring; and means for holding said member at various angular positions thereof against the bias of said throttle return spring independently of the position of said accelerator in accordance with various running conditions of the vehicle; in which a guide is arranged along the core of said accelerator wire which extends between said member and said switch and in which said guide is formed integrally with said bracket.
Claim 4
Dependent Claim
209 words
A carburetor control system for a motor vehicle including an apparatus to maintain the vehicle in running at some desired speed, the carburetor control system comprising: a torsion shaft for controlling an angular position of a throttle blade of a carburetor; a member fixedly mounted to said torsion shaft; a throttle return spring for biasing said member in one rotational direction; an accelerator; an accelerator wire including an outer casing and a core extending through said outer casing, said outer casing having, at an end adjacent to said member, a switch stop spaced from said member and fixed to a fixed portion of the vehicle body by a bracket, said core having one end engaging said member and an opposite end operatively connected to said accelerator and arranged to transmit motion of said accelerator to said member against said throttle return spring; and means for holding said member at various angular positions thereof against the bias of said throttle return spring independently of the position of said accelerator in accordance with various running conditions of the vehicle; in which a guide is arranged along the core of said accelerator wire which extends between said member and said switch and in which said guide is formed integrally with said bracket.
