Abstract
Abstract Normally-open switches in series with a power source to an alarm device are closed by simultaneous actuation of a motor vehicle clutch and accelerator to provide an alarm to the operator. Means are provided for preventing the generation of an alarm during low-gear start-up and/or during synchronized operation of the controls for gear changing.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
An alarm system for a motor vehicle of the type having a manually operated clutch and a manually operated accelerator comprising an alarm device operative when energized to produce an alarm; means for preventing said energizing at least during starting said motor vehicle into motion and being effective during small values of operation of said accelerator and ineffective at large values thereof; first and second normally open switches in series between an electrical power source and said alarm device; first means for closing said first switch whenever said clutch is actuated; second means for closing said second switch whenever said accelerator is actuated more than a predetermined amount; and said predetermined amount being greater than an amount employed during actuation of said clutch during startup and properly synchronized gear change.
Claim 2
Dependent Claim
130 words
An alarm system for a motor vehicle of the type having a manually operated clutch and a manually operated accelerator comprising an alarm device operative when energized to produce an alarm; means for preventing said energizing at least during starting said motor vehicle into motion and being effective during small values of operation of said accelerator and ineffective at large values thereof; first and second normally open switches in series between an electrical power source and said alarm device; first means for closing said first switch whenever said clutch is actuated; second means for closing said second switch whenever said accelerator is actuated more than a predetermined amount; and said predetermined amount being greater than an amount employed during actuation of said clutch during startup and properly synchronized gear change.
Claim 3
Dependent Claim
91 words
An alarm system for a motor vehicle of the type having a manually operated clutch and a manually operated accelerator comprising an alarm device operative when energized to produce an alarm; an electrical power source; a first switch interposed between the electrical power source and the alarm device; a second switch interposed between the electrical power source and the alarm device; first means for actuating said first switch whenever said clutch is actuated; and second means for actuating said second switch whenever said accelerator is actuated more than a predetermined amount.
Claim 4
Dependent Claim
91 words
An alarm system for a motor vehicle of the type having a manually operated clutch and a manually operated accelerator comprising an alarm device operative when energized to produce an alarm; an electrical power source; a first switch interposed between the electrical power source and the alarm device; a second switch interposed between the electrical power source and the alarm device; first means for actuating said first switch whenever said clutch is actuated; and second means for actuating said second switch whenever said accelerator is actuated more than a predetermined amount.
Claim 5
Dependent Claim
30 words
The alarm system according to claim 2 wherein the first switch and the second switch are normally open and in series between the electrical power source and said alarm device.
Claim 6
Dependent Claim
29 words
The alarm system according to claim 2 wherein said predetermined amount is greater than an amount employed during actuation of said clutch during startup and properly synchronized gear change.
Claim 7
Dependent Claim
23 words
An alarm system according to claim 2 including further means for preventing said energizing at least during starting said motor vehicle into motion.
Claim 8
Dependent Claim
27 words
An alarm system according to claim 5 wherein said further means includes switch means actuated by engagement of low gear in said vehicle for preventing said energizing.
Claim 9
Dependent Claim
24 words
An alarm system according to claim 5 wherein said means includes a delay for preventing said energizing during short periods of said simultaneous operation.
Claim 10
Dependent Claim
29 words
An alarm system according to claim 5 wherein said further means includes switch means actuated by a tachometer for preventing said energizing at engine speeds below a predetermined value.
Claim 11
Dependent Claim
28 words
An alarm system according to claim 5 wherein said further means is effective during small values of operation of said accelerator and is ineffective at large values thereof.
Claim 12
Dependent Claim
37 words
An alarm system according to claim 9 wherein said further means includes a switch actuated by a pressure in an engine of said motor vehicle, said pressure being variable with varying amounts of actuation of said accelerator.
Claim 13
Dependent Claim
149 words
An alarm system according to claim 1 wherein each of said first and second switches includes: a housing; a sliding block in said housing; means coupled to one of said clutch and accelerator for moving said sliding block from a first position to a second position in said housing; first and second electric terminals in said housing; first and second spaced-apart contact devices connected respectively to said first and second electrical terminals and bearing at first and second spaced-apart location on said sliding block; a bridge contact on said sliding block; said bridge contact being in contact with no more than one of said contact devices when said sliding block is in said first position; and said bridge contact being in contact with both of said contact devices when said sliding block is in said second position whereby electrical contact is made between said first and second electrical terminals.
Claim 14
Dependent Claim
21 words
An alarm system according to claim 11 wherein said further means being a substantial distance between said first and second positions.
