Abstract
Abstract A sleeve attached to an automobile accelerator rod, the sleeve having circumferential ribs and grooves forming a longitudinal cammed configuration which coacts with a microswitch as the accelerator rod is moved back and forth. Relaxation of the foot pressure on the accelerator rod causes relative movement between the cammed surface of the sleeve and the microswitch, alternately activating a flashing indicator.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
194 words
A deceleration warning device, in combination with a vehicle acceleration system comprising: a. switch means including an actuating member, a stop member and spring means urging the actuating member against the stop member into a primed position, wherein the actuating member can actuate the switch means on reciprocation, b. a sleeve having a plurality of ribs and grooves, c. the actuating member operatively engaging the ribs and grooves, d. indicator means connected to the switch means, and e. movable means in the acceleration system including an accelerator rod adjustably mounting the sleeve, and providing relative movement in one direction, during deceleration, between the switch means and the sleeve to reciprocate the primed actuating member engaging the ribs and grooves for actuating the switch means and alternately activating and deactivating the indicator means upon continued relative movement of the switch means and the sleeve in said one direction during deceleration, f. the accelerator rod providing relative movement in the other direction, during acceleration, between the switch means and the sleeve to urge the actuating member away from the stop member and out of the primed position whereby the actuating member cannot actuate the switch means.
Claim 2
Dependent Claim
194 words
A deceleration warning device, in combination with a vehicle acceleration system comprising: a. switch means including an actuating member, a stop member and spring means urging the actuating member against the stop member into a primed position, wherein the actuating member can actuate the switch means on reciprocation, b. a sleeve having a plurality of ribs and grooves, c. the actuating member operatively engaging the ribs and grooves, d. indicator means connected to the switch means, and e. movable means in the acceleration system including an accelerator rod adjustably mounting the sleeve, and providing relative movement in one direction, during deceleration, between the switch means and the sleeve to reciprocate the primed actuating member engaging the ribs and grooves for actuating the switch means and alternately activating and deactivating the indicator means upon continued relative movement of the switch means and the sleeve in said one direction during deceleration, f. the accelerator rod providing relative movement in the other direction, during acceleration, between the switch means and the sleeve to urge the actuating member away from the stop member and out of the primed position whereby the actuating member cannot actuate the switch means.
Claim 3
Dependent Claim
103 words
A deceleration warning device as defined in claim 1, in which: g. the sleeve is cylindrical and has a plurality of circumferential ribs and grooves disposed in spaced, alternate Relation along the length of the sleeve, h. the switch means includes a pivoted lever arm member carrying the actuating member a spaced distance from the pivot axis and a pushbutton disposed in engaging relation to said pivoted lever arm member at a distance from the pivot axis that is less than the distance between the pivot axis and the actuating member, and i. bracket means adjustably secure the switch means to a support.
Claim 4
Dependent Claim
31 words
A deceleration warning device as defined in claim 2, in which: j. the sleeve is longitudinally split into two matching and substantially similar elements mutually connected to embrace the accelerator rod.
