Abstract
Abstract In a manual control system for the throttle of a vehicle engine, a control member connected with the throttle is spring biased to a rest position and is movable to selected operative positions by means of a handle which is located convenient to the operator. An electromagnetic brake for holding the control member in set position is controlled by switches connected in series and including a manual switch on the handle, a switch controlled by the position of the control member, a switch controlled by the vehicle brake, and a switch controlled by the vehicle clutch.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
264 words
A control system for controlling the fuel control means of a combustion engine of a motor vehicle having an operator station and brake control means at said operator station, said system comprising a manually movable control member having handle means at said operator station in position for convenient hand operation by the operator of said vehicle, means connecting said control member with said fuel control means, said control member being manually movable by said handle means from a rest position in which said fuel control means is in engine idling condition to any selected operative position for desired fuel supply to the engine, means biasing said control member to said rest position, means including electromagnetic means for holding said control member in selected operative position when said electromagnetic means is energized, circuit means for energizing said electromagnetic means including in series connection a current source, said electromagnetic means and at least two switch means, a first one of said switch means being normally closed and being opened by actuation of said brake control means to deenergize said electromagnetic means and thereby free said control member for movement by said biasing means to said rest position, and a second of said switch means being normally closed and manually operable, and manual switch control means on said handle means, said switch control means being connected with said second switch means and being hand operable by the operator when operating said handle means to open said second switch to deenergize said electromagnetic means and thereby free said control member for movement by the operator to selected position.
Claim 2
Dependent Claim
264 words
A control system for controlling the fuel control means of a combustion engine of a motor vehicle having an operator station and brake control means at said operator station, said system comprising a manually movable control member having handle means at said operator station in position for convenient hand operation by the operator of said vehicle, means connecting said control member with said fuel control means, said control member being manually movable by said handle means from a rest position in which said fuel control means is in engine idling condition to any selected operative position for desired fuel supply to the engine, means biasing said control member to said rest position, means including electromagnetic means for holding said control member in selected operative position when said electromagnetic means is energized, circuit means for energizing said electromagnetic means including in series connection a current source, said electromagnetic means and at least two switch means, a first one of said switch means being normally closed and being opened by actuation of said brake control means to deenergize said electromagnetic means and thereby free said control member for movement by said biasing means to said rest position, and a second of said switch means being normally closed and manually operable, and manual switch control means on said handle means, said switch control means being connected with said second switch means and being hand operable by the operator when operating said handle means to open said second switch to deenergize said electromagnetic means and thereby free said control member for movement by the operator to selected position.
Claim 3
Dependent Claim
40 words
A control system according to claim 1, in which said movable member comprises a rotatable disc, and said holding means comprises brake means operable by said electromagnetic means to hold said disc against rotation when said electromagnetic means is energized.
Claim 4
Dependent Claim
47 words
A control system according to claim 2, in which said brake means comprises a stationary disc coaxial with said rotatable discs, and in which said electromagnetic means is operable when energized to draw said discs together so that said stationary disc holds said rotatable disc against rotation.
Claim 5
Dependent Claim
68 words
A control system according to claim 3, in which said discs comprises ferromagnetic material, and in which said electromagnetic means comprises said discs and a magnet winding in a recess in said stationary disc, said stationary disc comprising a core of an electromagnet having said magnet winding and said rotatable disc comprising an armature of said electromagnet, said disc being thereby drawn together when said winding is energized.
Claim 6
Dependent Claim
30 words

Claim 7
Dependent Claim
48 words
A control system according to claim 3, in which one of said discs is on a shaft extending through the other said disc, and in which said electromagnetic means comprises a solenoid connected with said shaft and operable to move said shaft axially to pull said disc together.
Claim 8
Dependent Claim
20 words
A control system according to claim 6, further comprising a friction disc between said rotatable disc and said stationary disc.
Claim 9
Dependent Claim
34 words
A control system according to claim 6, further comprising means for adjustably varying the position of said solenoid axially of said shaft to adjust the pressure between said disc when said solenoid is energized.
Claim 10
Dependent Claim
27 words
A control system according to claim 3, in which said handle means comprises a rod projecting radially of said rotatable disc and a handle on said rod.
Claim 11
Dependent Claim
