Switching apparatus for mass transit vehicle

Claim 2

In switching apparatus for a mass transit vehicle having support wheels and controllable to pass from a first roadway onto a selected one of a second roadway and a third roadway, with said apparatus including a pair of tracks for said support wheels, the combination of two guide members positioned between said tracks and with each of said guide members having a top flange, first guidance means connected to said vehicle and in substantially fixed position relative to said vehicle to pass between and cooperate with said two guide members, second guidance means connected to said vehicle and movable in position relative to said vehicle to be cooperative with one of said two guide members for controlling the vehicle to pass onto the second roadway, and third guidance means connected to said vehicle and movable in position relative to said vehicle to be cooperative with the other of said two guide members for controlling the vehicle to pass onto the third roadway.

Claim 3

The apparatus of claim 1, with said first guidance means including a guide wheel positioned to remain below the top flanges of the latter two guide members.

Claim 4

The apparatus of claim 1, with the second guidance means including a guide wheel movable between a first position below the top flanges of said two guide members and a second position above the top flanges of the latter two guide members.

Claim 5

The apparatus of claim 1, with said first guidance means being positioned below the top flanges of said two guide members.

Claim 6

The apparatus of claim 1, with said third guidance means being coupled with the second guidance means such that when the second guidance means is positioned to be operative with said one guide member the third guidance means is positioned not to be operative with said other guide member and when the third guidance means is positioned to be operative with said other guide member the second guidance means is positioned not to be operative with said one guide member.

Claim 7

In apparatus for controlling a mass transit vehicle having support wheels to switch from a first roadway onto a second roadway, with said apparatus including a pair of tracks for said support wheels, the combination of two guide members positioned between said tracks and with each said guide member having a top flange, a first guide wheel connected to said vehicle in substantially fixed vertical position for operation relative to and between said two guide members, a second guide wheel connected to said vehicle and movable in vertical position relative to said two guide members and selectively operative with one of the latter guide members to provide a first predetermined operation of the vehicle in relation to the second roadway, and a third guide wheel connected to said vehicle and movable in vertical position relative to said two guide members and selectively operative with the other of the latter guide members to provide a second predetermined operation of the vehicle in relation to the second roadway.

Claim 8

In apparatus for controlling a mass transit vehicle having support wheels to switch from a first roadway onto a second roadway, with said apparatus including a pair of tracks for said support wheels, the combination of two guide members positioned between said tracks and with each said guide member having a top flange, a first guide wheel connected to said vehicle in substantially fixed vertical position for operation relative to and between said two guide members, a second guide wheel connected to said vehicle and movable in vertical position relative to said two guide members and selectively operative with one of the latter guide members to provide a first predetermined operation of the vehicle in relation to the second roadway, and a third guide wheel connected to said vehicle and movable in vertical position relative to said two guide members and selectively operative with the other of the latter guide members to provide a second predetermined operation of the vehicle in relation to the second roadway.

Claim 9

The apparatus of claim 6, with the first guide wheel being operative to remain below the top flange of each of the latter guide members.

Claim 10

The apparatus of claim 6, with the second guide wheel being vertically movable between a first position below the top flange of each said guide member and a second position above the top flange of each said guide member.

Claim 11

The apparatus of claim 6, with said two guide members each having a top flange extending in a direction toward said first guide wheel, and with said first guide wheel being operative below the respective top flanges of the latter two guide members.

Claim 12

The apparatus of claim 6, with the third guide wheel being coupled with the second guide wheel such that when the second guide wheel is raised above the top flanges of said two guide members the third guide wheel is lowered below the top flanges of the latter two guide members.

Claim 13

In apparatus for controlling a mass transit vehicle to pass from a first roadway onto a selected one of a second roadway and a third roadway, with said apparatus including a pair of tracks and a first elongated guide member and a second elongated guide member, with each said guide member being positioned between the roadway tracks and including a top flange, the combination of first guidance means connected to said vehicle in substantially fixed vertical position relative to each of the first and second guide members when the vehicle is passing through said apparatus such that the first guidance means passes between and along the length of the first and second guide members, second guidance means connected to said vehicle and movable in vertical position relative to the top flange of the first guide member for controlling the vehicle to pass onto the second roadway, and third guidance means connected to said vehicle and movable in vertical position relative to the top flange of the second guide member for controlling the vehicle to pass onto the third roadway.

Claim 14

In apparatus for controlling a mass transit vehicle to pass from a first roadway onto a selected one of a second roadway and a third roadway, with said apparatus including a pair of tracks and a first elongated guide member and a second elongated guide member, with each said guide member being positioned between the roadway tracks and including a top flange, the combination of first guidance means connected to said vehicle in substantially fixed vertical position relative to each of the first and second guide members when the vehicle is passing through said apparatus such that the first guidance means passes between and along the length of the first and second guide members, second guidance means connected to said vehicle and movable in vertical position relative to the top flange of the first guide member for controlling the vehicle to pass onto the second roadway, and third guidance means connected to said vehicle and movable in vertical position relative to the top flange of the second guide member for controlling the vehicle to pass onto the third roadway.

Claim 15

The apparatus of claim 11, with the first guidance means including a guide wheel positioned to ride below the top flange of each said guide member, with the top flange of each said guide member extending toward said first guidance means.

Claim 16

The apparatus of claim 11, with the top flange of the first guide member permitting the second guidance means including a guide wheel to move between a first position above the top flange of the first guide member and a second position below the top flange of the first guide member.

Claim 17

The apparatus of claim 11, with said third guidance means being coupled with the second guidance means such that when the second guidance means is lowered to be operative with said first guide member the third guidance means is raised to be not operative with the second guide member and when the third guidance means is lowered to be operative with the second guide member the second guidance means is raised to be not operative with the first guide member.
