Abstract
Abstract A safety control system for use in mobile vehicles driven by a throttle controlled engine. The safety control system, upon actuation of the vehicle brakes, automatically brings the engine throttle into its idling position, irrespective of the setting of the engine throttle control and maintains it in this position as long as the vehicle brakes are being applied. The safety control system also brings the engine throttle into its idling position upon return of the throttle control lever to its idling position, irrespective of the position of the throttle control cable connecting engine throttle and throttle control lever.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
187 words
In a mobile vehicle comprising a frame, propelling means attached to said frame, an engine mounted on said frame and operably connected to said propelling means to impart motion to said vehicle, engine speed control means including engine throttling means, spring biasing means biasing said engine throttling means towards engine idling position, speed control setting means including mechanical motion transmitting means arranged to operate said engine throttling means, vehicle brake means and vehicle brake actuating means, the combination therewith of a safety control system interposed between said engine throttling means and said mechanical motion transmitting means of said speed control setting means, said safety control system having signal generating means disposed to generate a signal responsive to at least one given operator action, and disconnecting means responsive to said signal from said signal generating means disposed to actuate said disconnecting means, disconnecting said mechanical motion transmitting means of said speed control setting means from said engine throttle means thereby permitting said engine throttling means to bring the engine to the idling condition irrespective of the position of said mechanical motion transmitting means and said engine throttling means.
Claim 2
Dependent Claim
187 words
In a mobile vehicle comprising a frame, propelling means attached to said frame, an engine mounted on said frame and operably connected to said propelling means to impart motion to said vehicle, engine speed control means including engine throttling means, spring biasing means biasing said engine throttling means towards engine idling position, speed control setting means including mechanical motion transmitting means arranged to operate said engine throttling means, vehicle brake means and vehicle brake actuating means, the combination therewith of a safety control system interposed between said engine throttling means and said mechanical motion transmitting means of said speed control setting means, said safety control system having signal generating means disposed to generate a signal responsive to at least one given operator action, and disconnecting means responsive to said signal from said signal generating means disposed to actuate said disconnecting means, disconnecting said mechanical motion transmitting means of said speed control setting means from said engine throttle means thereby permitting said engine throttling means to bring the engine to the idling condition irrespective of the position of said mechanical motion transmitting means and said engine throttling means.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
29 words
The combination of claim 1 further characterized by said signal generating means having means disposed to generate said signal responsive to an actuated position of said brake actuating means.
Claim 5
Dependent Claim
48 words
The combination of claim 1 further characterized by said signal generating means having first means disposed to generate said signal responsive to the position of said speed control setting means and second means disposed to generate said signal responsive to an actuated position of said brake actuating means.
Claim 6
Dependent Claim
26 words

Claim 8
Dependent Claim
55 words
The conbination of claim 6 further characterized by said disconnecting means having locking means, spring means biasing said locking means towards a position connecting said engine throttling means to said speed control setting means and solenoid means operable through said locking means disposed to disconnect said engine throttling means from said speed control setting means.
Claim 9
Dependent Claim
42 words
The conbination of claim 7 further characterized by said locking means having rod means connected to said speed control setting means, said rod means having groove means, and plunger means operable by said solenoid means to engage and disengage said groove means.
Claim 10
Dependent Claim
98 words
The combination of claim 7 further characterized by said locking means interconnecting said engine speed control setting means and said engine throttling means, said locking means including rod means having groove means, and sleeve means, said sleeve means having circumferentially speced holes, ball means guided in said holes and arranged to engage and disengage said groove means, solenoid actuated cam means guided on said sleeve means and arranged to operate said ball means, spring means to bias said cam means towards engagement with said ball means and solenoid means to disengage said cam means from said ball means.
Claim 11
Dependent Claim
25 words
The combination of claim 6 further characterized by said solenoid actuating means having switching means responsive to a given position of said brake actuating means.
Claim 12
Dependent Claim
26 words
The combination of claim 6 further characterized by said solenoid actuating means having switching means responsive to a given position of said speed control setting means.
Claim 13
Dependent Claim
33 words
The combination of claim 6 further characterized by said solenoid actuating means having first switching means responsive to said brake actuating means and second switching means responsive to said speed control setting means.
Claim 14
Dependent Claim
75 words
The combination of claim 11 further characterized by said speed control setting means having control lever means, throttle control cable means operably connecting said control lever means and said disconnecting means, first spring means biasing said throttle control cable means towards engagement with said disconnecting means and said control lever means and second spring means biasing said control lever means towards disengagement with said throttle control cable means and engagement with said second switching means.
