Abstract
Abstract The subject invention relates to a switching device which will be activated by the sudden release of an automotive accelerator pedal. A pendulum arm is secured to the accelerator linkage and will operate when the position of the linkage is suddenly changed, but will not operate when the position is changed at a normal speed. A switch unit enclosed in a casing has a clevice type switch arm which extends through the casing to engage the pendulum arm when the accelerator pedal is released suddenly thereby to close two pairs of contacts. Three circuits are completed by the closing of the contacts through which current from a power source causes the vehicle''s stop lamp to illuminate, a signal lamp within the visual range of the vehicle driver to illuminate, and a flasher unit to energize. The flasher unit, after a predetermined period of time, conveys current to an electromagnet secured within the casing which causes the switch unit to reset, whereby the contacts are disengaged and the circuits are broken.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
A switch comprising: a. a casing; b. a load circuit for energizing a remote device; c. first contact means in said casing for opening and closing said load circuit; d. actuating means for manipulating said first contact means so that said load circuit will be opened and closed, selectively; e. a time delay reset circuit for resetting said actuating means; and f. a second contact meAns carried on said actuating means for opening and closing said time delay reset circuit.
Claim 2
Dependent Claim
80 words
A switch comprising: a. a casing; b. a load circuit for energizing a remote device; c. first contact means in said casing for opening and closing said load circuit; d. actuating means for manipulating said first contact means so that said load circuit will be opened and closed, selectively; e. a time delay reset circuit for resetting said actuating means; and f. a second contact meAns carried on said actuating means for opening and closing said time delay reset circuit.
Claim 3
Dependent Claim
56 words
The switch of claim 1, wherein said time delay reset circuit includes: a. delay means for delaying current for a predetermined time; b. a first conductor connecting said delay means and said contact means; c. electromagnetic means for resetting said actuating means; and d. a second conductor for connecting said delay means and said electromagnet means.
Claim 4
Independent Claim
121 words
An apparatus for use in a vehicle in combination with an existing accelerator linkage to provide early warning of deceleration prior to an emergency stop comprising: a. a casing: b. a load circuit for energizing a remote device; c. first contact means in said casing for opening and closing said load circuit; d. actuating means for manipulating said first contact means so that said load circuit will open and close, selectively; e. a time delay circuit for resetting said actuating means; f. second contact means carried on said actuating means for opening and closing said time delay reset circuit; and g. pendulum means secured to the existing accelerator linkage for engaging said actuating means when said accelerator linkage is released suddenly.
Claim 5
Independent Claim
121 words
An apparatus for use in a vehicle in combination with an existing accelerator linkage to provide early warning of deceleration prior to an emergency stop comprising: a. a casing: b. a load circuit for energizing a remote device; c. first contact means in said casing for opening and closing said load circuit; d. actuating means for manipulating said first contact means so that said load circuit will open and close, selectively; e. a time delay circuit for resetting said actuating means; f. second contact means carried on said actuating means for opening and closing said time delay reset circuit; and g. pendulum means secured to the existing accelerator linkage for engaging said actuating means when said accelerator linkage is released suddenly.
Claim 6
Dependent Claim
30 words
The apparatus of claim 3, wherein said actuating means includes opposed, hinged first and second clevis arms which will operate with a ''''snap action'''' between a first and second position.
Claim 7
Dependent Claim
108 words
The apparatus of claim 4, wherein said first contact means includes a first contact carried on said first arm and a rigidly, fixed second contact carried within said casing for engaging said first contact to close said load circuit when said actuating means is in the second position, and wherein said second contact means includes a third contact carried on said first arm and a fourth contact for engaging said third contact to close said time delay reset circuit when said actuating means is in the second position, said fourth contact being movably mounted within said casing in order to provide a more positive engagement between said contacts.
Claim 8
Dependent Claim
56 words
The apparatus of claim 3, wherein said time delay reset circuit includes: a. delay means for delaying current for a predetermined time; b. a first conductor connecting said delay means and said contact means; c. electromagnetic means for resetting said actuating means; and d. a second conductor for connecting said delay means and said electromagnetic means.
Claim 9
Dependent Claim
60 words
The apparatus of claim 3, wherein said pendulum means includes: a. a support mounted on the existing accelerator linkage; b. a pendulum pivotally mounted on said support; c. a bracket for limiting the arc of movement of said pendulum; and d. a spring assembly for preventing said pendulum from moving when the accelerator linkage is moved in a normal manner.
Claim 10
Dependent Claim
60 words
The apparatus of claim 5, wherein said pendulum means includes: a. a support mounted on the existing accelerator linkage; b. a pendulum pivotally mounted on said support; c. a bracket for limiting the arc of movement of said pendulum; and d. a spring assembly for preventing said pendulum from moving when the accelerator linkage is moved in a normal manner.
Claim 11
Dependent Claim
56 words
The apparatus of claim 8, wherein said time delay reset circuit includes: a. delay means for delaying current for a predetermined time; b. a first conductor connecting said delay means and said contact means; c. electromagnetic means for resetting said actuating means; and d. a second conductor for connecting said delay means and said electromagnetic means.
