Driverless vehicle turntable system
First Claim
1. A driverless vehicle turntable system comprising first and second stationary track, first and second turntables interconnected for simultaneous rotation for transferring driverless vehicles from said first set of tracks to said second set of tracks, each turntable having a set of tracks aligned with a set of tracks on the other turntable in one position of the turntables, each set of turntable tracks being aligned with one of said first and second sets of tracks in another position of the turntables, a discrete rotatable drive shaft on each turntable for propelling a vehicle supported by its associated turntable, said drive shafts being coaxial when the tracks on said turntables are aligned with each other, and stationary tracks between and adjacent said turntables, said last-mentioned stationary tracks being aligned with the tracks on said turntables when said drive shafts are coaxial, a motor coupled to said first turntable for rotating said first turntable, and a connecting rod pivotably connected at its ends to said turntables so that said first turntable causes said second turntable to rotate in an opposite direction.

Abstract
A driverless turntable system is disclosed and includes two turntables coupled together for simutaneous rotation in opposite directions. A driverless vehicle enters the first turntable, is transferred to the second turntable, and then exits from the second turntable in a direction parallel to that when it entered the first turntable. Stationary tracks are provided adjacent the turntables for guiding the vehicles thereonto and therefrom.

4. A turntable system for transferring driverless vehicles between first and second sets of tracks comprising means including first and second turntables for transferring vehicles from a first set of tracks to a second set of tracks, each turntable having a set of tracks thereon, each turntable being rotatable about an upright axis so that tracks on the first turntable can be aligned with tracks on the second turntable in a vehicle transfer position of the turntables, means interconnecting said turntables for simultaneous rotation in opposite directions, means for rotating said turntables, a discrete vehicle propelling means supported on each turntable, selectively controlled vehicle stop means on each turntable for stopping a vehicle and interrupting the propelling effect of said vehicle propelling means, switches on said turntable for initiating rotation of said turntables, one said switch being on one turntable to initiate rotation of said one turntable in a first direction, and another switch being on the other turntable for initiating rotation of said one turntable in an opposite direction.
- 5. A turntable system for transferring driverless vehicles between first and second sets of tracks comprising means including first and second turntables for transferring vehicles from a first set of tracks to a second set of tracks, each turntable having a set of tracks thereon, each turntable being rotatable about an upright axis so that tracks on the first turntable can be aligned with tracks on the second turntable in a vehicle transfer position of the turntables, means interconnecting said turntables for simultaneous rotation in opposite directions, a discrete vehicle propelling means supported on each turntable, and selectively controlled vehicle stop means on each turntable for rotation therewith for stopping a vehicle and interrupting the propelling effect of said vehicle propelling means.

12. An automatic driverless turntable system comprising first and second horizontally disposed turntables rotatable about vertical axes, a set of tracks on each turntable, the tracks on said first turntable being parallel to said tracks on said second turntable in a vehicle receiving position of one of the turntables, when said one turntable is in a vehicle receiving position the other turntable being in a vehicle discharge position, the tracks on said first turntable being aligned with the tracks on said second turntable in a vehicle transfer position of said turntables, a motor means connected to one of said turntables for intermittently rotating said first turntable from a vehicle discharge position to its vehicle transfer position and then interrupting such rotation, a first switch means on said second turntable for initiating such rotation of the first turntable by said motor means, a second switch for initiating rotation of the first turntable from its vehicle transfer position to its vehicle discharge position by said motor means, means interconnecting said turntables for simultaneous rotation, a discrete drive shaft rotatably supported on each turntable between the tracks of each turntable, a discrete motor on each turntable coupled to its associated drive shaft, said drive shafts being parallel to each other when said one turntable is in its vehicle receiving position, and selectively controlled discrete vehicle stop means on each turntable for selectively stopping a vehicle and then permitting the vehicle to move off its associated turntable under the driving effect of its associated drive shaft as a function of the rotary position of the turntables.
