Abstract
Abstract A road supported, track guided vehicle: The vehicle has a body with a center of gravity and has a road wheel assembly near the center of gravity, which carries the load of the vehicle body. A rail guided rail wheel assembly is connected through a rigid arm by an articulated connection to the vehicle body. The arm extends forwardly of the body and serves to vertically position and to guide the vehicle. Electric power may be drawn through the wheel assembly.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
A track guided vehicle, comprising: a vehicle body with a front and a rear end and a center of gravity therebetween; a road wheel assembly, for traveling on a road surface, attached to said vehicle body near the center of gravity thereof; and a rail wheel assembly also attached to said vehicle body by means which holds said rail wheel assembly away from said center of gravity whereby said rail wheel assembly guides said body and the main load of said body is borne by said road wheel assembly; said means for attaching said rail wheel assembly to said body comprising a rigid supporting arm connected to said body and extending toward an end of said body, said arm having sufficient rigidity to prevent tipping of said body around said center of gravity and to support said body vertically.
Claim 2
Dependent Claim
139 words
A track guided vehicle, comprising: a vehicle body with a front and a rear end and a center of gravity therebetween; a road wheel assembly, for traveling on a road surface, attached to said vehicle body near the center of gravity thereof; and a rail wheel assembly also attached to said vehicle body by means which holds said rail wheel assembly away from said center of gravity whereby said rail wheel assembly guides said body and the main load of said body is borne by said road wheel assembly; said means for attaching said rail wheel assembly to said body comprising a rigid supporting arm connected to said body and extending toward an end of said body, said arm having sufficient rigidity to prevent tipping of said body around said center of gravity and to support said body vertically.
Claim 3
Dependent Claim
20 words
The vehicle of claim 1, wherein said rail wheel assembly is articulatedly connected to said body through said supporting arm.
Claim 4
Dependent Claim
19 words
The vehicle of claim 2, wherein said arm supports said rail assembly in front of said center of gravity.
Claim 5
Dependent Claim
12 words
The vehicle of claim 2, wherein said road wheel assembly is uniaxial.
Claim 6
Dependent Claim
21 words
The vehicle of claim 4, further comprising motor means connected with said road wheel assembly for driving said road wheel assembly.
Claim 7
Dependent Claim
37 words
In combination, the vehicle of claim 1 and a rail wheel assembly guiding rail system; said rail wheel assembly being guided in said guide rail system and being blocked against vertical shifting by said guide rail system.
Claim 8
Dependent Claim
20 words
The combination of claim 6, wherein said rail system is overhead and said rail wheel assembly is above said body.
Claim 9
Dependent Claim
48 words
The combination of claim 7, further comprising electrically operable motor means connected with said road wheel assembly for driving said road wheel assembly; current collectors in said rail wheel assembly being connected to said motor means for driving said motor means through electricity gathered by said current collectors.
Claim 10
Dependent Claim
26 words
The combination of claim 8, wherein said rail system is electrified and said rail wheel assembly current collectors are in contact with said electrified rail system.
Claim 11
Dependent Claim
134 words
A track guided vehicle comprising: a vehicle body having a front and rear end and a centeR of gravity therebetween; a road wheel assembly, for traveling on a road surface, attached to said vehicle body near the center of gravity thereof; and a rail wheel assembly carried by said vehicle body, said rail wheel assembly comprising an arm formed integrally with said vehicle body for supporting said rail wheel assembly away from the center of gravity of said vehicle body whereby said rail wheel assembly guides said vehicle and the main load of said body is borne by the road wheel assembly; said arm extending from said body toward one end thereof and having sufficient rigidity to support said vehicle body vertically and prevent the tipping of said body around the center of gravity.
Claim 12
Dependent Claim
134 words
A track guided vehicle comprising: a vehicle body having a front and rear end and a centeR of gravity therebetween; a road wheel assembly, for traveling on a road surface, attached to said vehicle body near the center of gravity thereof; and a rail wheel assembly carried by said vehicle body, said rail wheel assembly comprising an arm formed integrally with said vehicle body for supporting said rail wheel assembly away from the center of gravity of said vehicle body whereby said rail wheel assembly guides said vehicle and the main load of said body is borne by the road wheel assembly; said arm extending from said body toward one end thereof and having sufficient rigidity to support said vehicle body vertically and prevent the tipping of said body around the center of gravity.
