Abstract
Abstract Usually wasted kinetic energy derived from relative movements of the vehicle wheels and chassis frame is converted into usable electric energy by the operation of a simplified chassis-mounted mechanical drive operatively coupled with alternators or generators through a pair of oppositely active and inactive transmission devices driven by a common rotary element, such as a gear.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
In a system for generating electrical power for a vehicle having a relatively movable frame member and axle connected by a resilient suspension, a pair of opposing rotary current generating devices mounted in coaxial relationship on said frame member, flywheel means connected directly to and rotatable respectively with said generating devices for respectively maintaining the rotation of said devices during periods in which no external force is applied thereto, direct driving means including an alternately oppositely rotating element common to the generating devices connected with and driven by said axle during the rise and fall thereof relative to the frame member, and oppositely active and inactive one-way rotational drive means respectively connected between said generating devices and said alternately oppositely rotating element.
Claim 2
Dependent Claim
122 words
In a system for generating electrical power for a vehicle having a relatively movable frame member and axle connected by a resilient suspension, a pair of opposing rotary current generating devices mounted in coaxial relationship on said frame member, flywheel means connected directly to and rotatable respectively with said generating devices for respectively maintaining the rotation of said devices during periods in which no external force is applied thereto, direct driving means including an alternately oppositely rotating element common to the generating devices connected with and driven by said axle during the rise and fall thereof relative to the frame member, and oppositely active and inactive one-way rotational drive means respectively connected between said generating devices and said alternately oppositely rotating element.
Claim 3
Dependent Claim
53 words
In a system for generating electrical power as defined in claim 1, said direct driving means further including a rack bar connected with and reciprocated by said axle responsive to the rise and fall of the axle and being drivingly engaged to said alternately oppositely rotating element, and said element comprising a pinion.
Claim 4
Dependent Claim
39 words
In a system for generating electrical power as defined in claim 2, and spring means on said axle connected with the rack bar to bias the teeth of the rack bar into mesh with the teeth of the pinion.
Claim 5
Dependent Claim
26 words
In a system for generating electrical power as defined in claim 3, and additional snubbing spring means connected with opposite end portions of said rack bar.
Claim 6
Dependent Claim
68 words
In a system for generating electrical power as defined in claim 1, and said oppositely active and inactive one-way rotational drive means comprising a pair of coaxial shafts connected between said alternately oppositely rotating element and shafts of said current generating devices, and one-way active, one-way inactive ratchet drives for said shafts having driving connections with the shafts and having driven connections with said alternately oppositely rotating element.
Claim 7
Dependent Claim
59 words
In a system for generating electrical power as defined in claim 5, said ratchet drives comprising toothed ratchet collars fixed on said shafts, and coacting driving coil springs surrounding said shafts and having one-way driving terminals engaged with the one-way driving ratchet teeth of said collars and having opposite end terminals drivingly connected with said alternately oppositely rotating element.
Claim 8
Dependent Claim
42 words
In a system for generating electrical power as defined in claim 6, and said direct driving means including a rack bar connected with and reciprocated by said axle and being drivingly engaged with said element, and said element comprising a pinion gear.
Claim 9
Dependent Claim
34 words
In a system for generating electrical power as defined in claim 5, wherein said flywheel means are respectively on the shafts of said current generating devices between said generating devices and their drive means.
Claim 10
Dependent Claim
53 words
In a system for generating electrical power as defined in claim 1, and said direct driving means further including a reciprocating drive element connected with said axle, a platform extension on said frame member and supporting said current generating devices, and guide bearing means for said reciprocating drive element on the platform extension.
