Abstract
Abstract A rapid transportation system which includes a channel trackway with electromagnets positioned therealong. The magnets are individually energizable and are arranged to support and propel the pallets associated therewith. The pallets are arranged to support a motor vehicle, a passenger pod, a freight pod, or a work pod. The magnets of the trackway are used to divert a pallet from the main trackway to adjacent trackways such as a station or depot through a switch having no moving parts. A mechanical diverter is provided for preventing a pallet from becoming lodged in a partially switched condition to thereby tie-up the system.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
99 words
A rapid transit system comprising a trackway formed of solid material and having at least a pair of spaced apart parallel Tshaped slots formed therein, a plurality of electromagnets mounted in saiD trackway along said slots, a pallet positioned above said trackway, at least a pair of webs extending downwardly from said pallet into said T-shaped slots, a T bar integrally formed on the lower end of said webs, means for individually and progressively energizing the electromagnets in said trackway to exert electromotive force on said T bars to raise said pallet and propel said pallet along said trackway.
Claim 2
Dependent Claim
99 words
A rapid transit system comprising a trackway formed of solid material and having at least a pair of spaced apart parallel Tshaped slots formed therein, a plurality of electromagnets mounted in saiD trackway along said slots, a pallet positioned above said trackway, at least a pair of webs extending downwardly from said pallet into said T-shaped slots, a T bar integrally formed on the lower end of said webs, means for individually and progressively energizing the electromagnets in said trackway to exert electromotive force on said T bars to raise said pallet and propel said pallet along said trackway.
Claim 3
Dependent Claim
24 words
A device as claimed in claim 1 wherein the electromagnets are positioned above and below said T bar for balancing the magnetic loads thereon.
Claim 4
Dependent Claim
24 words
A device as claimed in claim 1 wherein means are provided in said system for moving a pallet off of said system as desired.
Claim 5
Dependent Claim
32 words
A device as claimed in claim 1 wherein electromagnetic and mechanical switching means is provided in said trackway and on said pallet for switching said pallet to a branch line as desired.
Claim 6
Dependent Claim
20 words
A device as claimed in claim 1 wherein said pallet is provided with means for supporting a motor vehicle thereon.
Claim 7
Dependent Claim
20 words
A device as claimed in claim 1 wherein said pallet is provided with means for supporting a passenger pod thereon.
Claim 8
Dependent Claim
35 words
A device as claimed in claim 1 wherein means are provided in said system for individually and successively energizing said electromagnets for controlling the position, speed and height of the pallets moving in said system.
Claim 9
Dependent Claim
45 words
A device as claimed in claim 7 wherein a plurality of branch lines are provided in said system with each of said branch lines having a switch through which the pallet moves controlled by a plurality of electric magnets in said trackway in said switch.
Claim 10
Dependent Claim
32 words
A device as claimed in claim 8 wherein stationary mechanical means are provided for guiding said pallet through said switch to remain in said trackway or to move into said branch line.
Claim 11
Dependent Claim
20 words
A device as claimed in claim 1 wherein a passenger carrying pod is secured to said pallet for movement therewith.
Claim 12
Dependent Claim
20 words
A device as claimed in claim 1 wherein a freight carrying pod is secured to said pallet for movement therewith.
Claim 13
Dependent Claim
43 words
A device as claimed in claim 1 wherein the electric magnets in said slot along said trackway are positioned above and below said slots and along each side of said slots for controlling the position of the pallet with respect to said trackway.
Claim 14
Dependent Claim
32 words
A device as claimed in claim 1 wherein means are provided for guiding a motor vehicle onto a pallet and additional means are provided for centering the pallet beneath said motor vehicle.
