Abstract
Abstract In a preferred embodiment an automobile having four extra accessory utility wheels mounted on hydraulic jacks, with the back two accessory wheels being connected for synchronized steering thereof in both lateral and forward directions of movement of the car as well as the forward two wheels being synchronized with one another for synchronized steering in both lateral and forward directions and there being switch means whereby the front wheels and the rear wheels may be synchronized to one another for the forward and/or lateral steering, and at least one of the sets of front and back accessory wheels being connected for and including propulsion means alternately drivable by the regular automobile motor or by an electrical motor, the electrical motor-including embodiment also including accessory batteries connected to provide electricity to any accessory electrical motor and also connected to continually charged if necessary by the generator of the automobile, this above described combination of this invention providing both parking advantages and emergency power and wheels in the event of flat tires or other mechanical difficulty requiring supplemental driving power for propulsion of the automobile for reasonably short periods of time to remove the automobile from hazardous traffic locations or to propel the automobile to an appropriate next-occurring filling station or repair facility.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
288 words
A motor vehicle accessory wheel and drive device comprising an automotive carriage and motor vehicle means having at least three wheels operatively mounted on separate front axle and rear axle means; an additional front third wheel and axle means including extension and retraction means for lowering to a position sufficiently extended that the motor and vehicle carriage are supportable at a height such that any wheel mounted on the front axle means is supportable above and free from contact with a normal roadway supporting surface, the forward third wheel axle means including operatively connected steering elements such that any supporting wheel thereof is steerable in both lateral and forward directions; a rearward fourth wheel and axle means including extension and retraction means for lowering to a position sufficiently extended that the motor and vehicle carriage are supportable at a height such that any wheel mounted on the front axle means is supportable above and free from contact with a normal roadway supporting surface, the rearward fourth wheel and axle means including operatively connected steering elements such that any supporting wheel thereof is steerable in both lateral and forward directions; and drive means connected to at least one of said third wheel and axle means and said fourth wheel and axle means, for propelling said at least one wheel and axle means rotatably whereby when supported on said at least one wheel and axle means said motor and carriage vehicle are propellable along a roadway surface thereby; said third and fourth wheel and axle means each including (a) a hydraulic cylinder rotatably-mounted on said carriage, and (b) an electric motor means operatively-mounted to rotatably drive the hydraulic cylinder, whereby an accessory wheel of the hydraulic cylinder is controlably steerable.
Claim 2
Dependent Claim
288 words
A motor vehicle accessory wheel and drive device comprising an automotive carriage and motor vehicle means having at least three wheels operatively mounted on separate front axle and rear axle means; an additional front third wheel and axle means including extension and retraction means for lowering to a position sufficiently extended that the motor and vehicle carriage are supportable at a height such that any wheel mounted on the front axle means is supportable above and free from contact with a normal roadway supporting surface, the forward third wheel axle means including operatively connected steering elements such that any supporting wheel thereof is steerable in both lateral and forward directions; a rearward fourth wheel and axle means including extension and retraction means for lowering to a position sufficiently extended that the motor and vehicle carriage are supportable at a height such that any wheel mounted on the front axle means is supportable above and free from contact with a normal roadway supporting surface, the rearward fourth wheel and axle means including operatively connected steering elements such that any supporting wheel thereof is steerable in both lateral and forward directions; and drive means connected to at least one of said third wheel and axle means and said fourth wheel and axle means, for propelling said at least one wheel and axle means rotatably whereby when supported on said at least one wheel and axle means said motor and carriage vehicle are propellable along a roadway surface thereby; said third and fourth wheel and axle means each including (a) a hydraulic cylinder rotatably-mounted on said carriage, and (b) an electric motor means operatively-mounted to rotatably drive the hydraulic cylinder, whereby an accessory wheel of the hydraulic cylinder is controlably steerable.
Claim 3
Dependent Claim
26 words
The device of claim 1, in which the means for extending said third and fourth wheel and axle means to extended states comprises hydraulic motor means.
Claim 4
Dependent Claim
43 words
A device of claim 1, in which the means for extending said third and fourth wheel and axle means to an extended state comprises a hydraulic motor means, and additionally including a supplemental battery means operatively connected to drive said hydraulic motor means.
Claim 5
Dependent Claim
23 words
A device of claim 1, including switch means for alternatively jointly or separately operating said third and said fourth wheel and axle means.
Claim 6
Dependent Claim
52 words
A device of claim 4, in which each of said third and fourth wheel and axle means includes a separate extendable accessory wheel adjacent to each forward and each rearward wheel of a conventional type of the carriage and motor vehicle means, and including means for extending separately each separate extendable wheel.
Claim 7
Dependent Claim
53 words
A device of claim 1, in which each accessory wheel has a rollaby-contacting surface contactable with a normal roadway supporting surface when the accessory wheel is in an extended state, said rollably-contacting surface being of a predetermined breadth greater than breadth of respective conventional wheels of the automotive carriage and motor vehicle means.
