Abstract

Apparatus and a system are provided for a trackless-roadway vehicle having internal and external propulsion energy sources; the external energy being obtained by a collector plow from electric power rails located in a conduit below the roadway. The collector plow, sensors, the plow elevating mechanism, and the plow steering mechanism are mounted on a laterally movable carriage on the underside of the vehicle. By means of servo-systems comprised of sensors, servo-amplifiers, and drive motors with associated gearing, the plow is automatically and continuously translated and orientated to maintain the plow arms in the vertical plane of the slot in the cover of the conduit. The plow consists of two arms, each with a contactor. When the plow is out of the conduit, the contactors lie in a single plane so that they may pass through the slot. After passing through the slot the contactors are brought to bear on the power rails by contra-rotation of the plow arms. Switching and relay means are employed to transfer the propulsion motor between the external and internal sources, to effect recharging of the internal source, and to control the limits of the horizontal and vertical travel of the plow.

Claims

1. A roadway vehicle having:

a. an internal and an external source of propulsion energy, the latter located in a conduit below the surface of the roadway;

said conduit having a slotted cover, and said external energy source being recessed out of the vertical plane of the slot.

b. a plow with elements for conducting energy to the vehicle and for contacting the external source through a slot in the conduit;

c. means for lowering the plow into the slot in the conduit and for raising the plow out of the slot;

d. means for positioning the plow relative to the external energy source to permit engagement of same outside of the vertical plane of the slot, and means for effecting engagement and disengagement between the conducting elements of the plow and the external energy source.

2. A vehicle as described in claim 1 having sensor means for determining the lateral position and angular orientation of the plow with respect to the conduit slot.

3. A vehicle as described in claim 2 having dirigible means for changing the lateral position and angular orientation of the plow with respect to the conduit slot.

4. A vehicle as described in claim 3 having the sensor means coacting with the means for laterally positioning and angularly orienting the plow whereby the plow is automatically made to lie in the vertical plane of the conduit slot.

5. A vehicle as described in claim 4 having the sensor means, the plow, the plow elevation means, and the plow angular orientation means mounted on a laterally movable carriage located on the underside of the vehicle, and having means for moving the carriage laterally, whereby the plow is automatically made to lie in the vertical plane of the conduit slot.

6. A vehicle as described in claim 4 having switching means controlling the elevation of the plow, whereby it is automatically raised or lowered upon the occurrance of preselected conditions.

7. A vehicle as described in claim 1 having switching means and recharging means, whereby the internal energy source is replenished by the external source.

8. For the vehicle described in claim 1, a conduit plow having:

a. a plow arm with a planar contactor;

b. means for holding the plow arm and the plane of the contactor in the vertical plane of the conduit slot so that the plow can be lowered into the conduit slot;

c. means for rotating the plow arm about its longitudinal axis after the contactor is in the conduit, whereby the contactor is held against the power rail in the conduit;

d. means for rotating the plow arm back to its original position so that the plow may pass out of the conduit slot.

9. A vehicle as described in claim 1 wherin the internal energy source is a secondary type electric battery.

10. A roadway vehicle having a plow with elements for conducting energy to the vehicle and for contacting an external source of propulsion energy located in a slotted conduit below the surface of the roadway, which vehicle is not mechanically guided by elements associated with the roadway while contacting the external source.
