Abstract
Abstract This disclosure relates to a roadway switch for self-guided vehicles having at least two selectable routes of travel. The switch includes at least two movable I-beams each having one end pivotally mounted for movement in two modes. A rotatable member supports the outer end of each of the movable I-beams and permits movement of the other end of the I-beams in three modes. An electric motor is incorporated for rotating the rotatable member between a first and second position whereby one of the I-beams establishes the route of travel for the self-guided vehicles.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
A switching arrangement for use in a vehicle roadway having at least two selectable routes of travel, comprising at least two switching members, each of said switching members having a first rotational and pivotal connection at one end thereof and a second rotational, translational and pivotal connection at the other end thereof, and an actuating mechanism including a rotatable member in the form of a circular sector crank and a driving means interconnecting said rotational, translational and pivotal connection of each of said switchiNg members so that the position of the said switching members may be switched to select the route of travel for a vehicle moving along said roadway.
Claim 2
Dependent Claim
110 words
A switching arrangement for use in a vehicle roadway having at least two selectable routes of travel, comprising at least two switching members, each of said switching members having a first rotational and pivotal connection at one end thereof and a second rotational, translational and pivotal connection at the other end thereof, and an actuating mechanism including a rotatable member in the form of a circular sector crank and a driving means interconnecting said rotational, translational and pivotal connection of each of said switchiNg members so that the position of the said switching members may be switched to select the route of travel for a vehicle moving along said roadway.
Claim 3
Dependent Claim
18 words
