Abstract
Abstract A power collection apparatus is disclosed for the purpose of power distribution from a central power supply to the propulsion motors of at least one mass transit vehicle operative with a predetermined roadway track, including one or more rail gaps and/or crossover switches, to permit the vehicle to transfer from one section to a second section of that roadway track. The power collection apparatus includes collector support apparatus carried by each vehicle and designed to be operative with a rail support member for three individual phase power rails, a ground rail and a signal rail, permitting high speed vehicle passage through a rail gap and a crossover switch.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A conductor assemblage for use with a rail electrification system, comprising in combination: (a) a set of vertically stacked collector shoes adapted for engagement with a group of vertically stacked live power rails of the electrification system; (b) said set comprising three shoes located in vertically spaced relation and adapted for disposition in horizontally opposite locations with respect to the group of live power rails; (c) a carrier; (d) means mounting the set of shoes on the carrier for limited, simultaneous vertical movement; and (e) a mechanical control device mounted on the carrier and connected with said set of shoes; said control device being engageable with a rail section of the electrification system and normally yieldably positioning the shoes of the set at a predetermined level on the carrier.
Claim 2
Dependent Claim
129 words

Claim 3
Dependent Claim
113 words
In power collection apparatus for a vehicle operative with a track having a vehicle support surface below which first and second conductive rails are positioned and above which first and second power rails are positioned, the combination of first collector means operative with said first conductive rail, second collector means operative with said first power rail, first collector support means operative with said vehicle and pivotally supporting each of said first and second collector means, third collector means operative with said second conductive rail, fourth collector means operative with said second power rail, and second collector support means operative with said vehicle and pivotally supporting each of said third and fourth collector means.
Claim 4
Dependent Claim
113 words
In power collection apparatus for a vehicle operative with a track having a vehicle support surface below which first and second conductive rails are positioned and above which first and second power rails are positioned, the combination of first collector means operative with said first conductive rail, second collector means operative with said first power rail, first collector support means operative with said vehicle and pivotally supporting each of said first and second collector means, third collector means operative with said second conductive rail, fourth collector means operative with said second power rail, and second collector support means operative with said vehicle and pivotally supporting each of said third and fourth collector means.
Claim 5
Dependent Claim
73 words
The power collection apparatus of claim 2, including first connection means between said first collector means and said second collector means such that the position of the second collector means is determined by the position of said first collector means, and second connection means between said third collector means and said fourth collector means such that the position of the fourth collector means is determined by the position of said third collector means.
Claim 6
Dependent Claim
39 words
The power collection apparatus of claim 2, with said first collector support means being positioned at one side of said power rails and with said second collector support means being positioned at the other side of said power rails.
Claim 7
Dependent Claim
54 words
The power collection apparatus of claim 2, with said first collector support means and said second collector support means being symmetrically positioned respectively at a first side of said power rails and at a second side of said power rails such that said vehicle can operate in each of two directions along said track.
