Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A support apparatus for a conductive rail operative with a vehicle moving along a roadway including spaced tracks and a guide beam having an upper flange and supported between those tracks, said vehicle having an electric motor connected to a collector shoe, the combination of: rail support means positioned above and coupled to the upper flange of said guide beam for positioning said rail substantially parallel to said spaced tracks such that said collector shoe cooperates with said rail to energize said motor, with said rail support means including an insertion slot, and rail mounting means coupled between said rail and said rail support means for holding said rail, with said rail mounting means including at least one fastener member having a predetermined shape operative with said insertion slot of said rail support means to fasten securely said rail to said rail support means.
Claim 2
Dependent Claim
144 words
A support apparatus for a conductive rail operative with a vehicle moving along a roadway including spaced tracks and a guide beam having an upper flange and supported between those tracks, said vehicle having an electric motor connected to a collector shoe, the combination of: rail support means positioned above and coupled to the upper flange of said guide beam for positioning said rail substantially parallel to said spaced tracks such that said collector shoe cooperates with said rail to energize said motor, with said rail support means including an insertion slot, and rail mounting means coupled between said rail and said rail support means for holding said rail, with said rail mounting means including at least one fastener member having a predetermined shape operative with said insertion slot of said rail support means to fasten securely said rail to said rail support means.
Claim 3
Dependent Claim
57 words
The support apparatus of claim 1, operative with a plurality of conductive rails, with said rail support means including a plurality of insertion slots and with one of said rail mounting means being provided for each of said conductive rails and being coupled between that conductive rail and a different insertion slot in said rail support means.
Claim 4
Dependent Claim
64 words
The support apparatus of claim 1, with said rail being positioned by a plurality of said rail support means positioned above and coupled to the upper flange of said guide beam at predetermined locations along the length of said rail and with a different one of said rail mounting means being coupled between said rail and each of said plurality of rail support means.
Claim 5
Dependent Claim
47 words
The support apparatus of claim 1, with said rail support means including an insertion slot and with said fastener member being tapered in shape to be operative with said slot and adapted to be bent apart to wedge the rail mounting means against the rail support means.
Claim 6
Dependent Claim
44 words
The support apparatus of claim 1, with said rail mounting means having ends adapted to be opened to accept said rail and then be closed upon insertion of said rail mounting means into said slot for clamping said rail to said rail support means.
Claim 7
Dependent Claim
28 words
The support apparatus of claim 1, with said rail mounting means having fastener tabs which can be separated to wedge the rail mounting means into said insertion slot.
Claim 8
Dependent Claim
72 words
The support apparatus of claim 1, operative with a plurality of conductive rails, with a rail mounting means having fastener tabs provided for each conductive rail for holding the latter said rail, and with said rail support means including a different insertion slot for each of said rail mounting means and operative with the fastener tabs thereof for positioning said plurality of conductive rails in a predetermined arrangement relative to said roadway.
