Abstract
Abstract A monorail track switch comprised of two swinging switch beams pivoted to track beam ends from which the wheeled trucks of trains are to be directed onto a continuing main line track beam, freedom for switch movements being provided for by anti-friction articulation of all members thereof, and characterized by a retractile gate that is replaceable between the free end faces of the two swinging switch beams respectively, and the opposed end face of the continuing main line track beam.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
An articulated self-aligning switch for elevated monorail track, and including; a pair of swinging switch beams with bearing means pivotally mounting the switch beams to the terminal ends of a main line track beam and a lateral track beam respectively, link means coupling the pair of switch beams to swing together and in spaced relation to each other and into and out of alignment with a continuing main line track beam, a retractile gate secured to ways and shiftable into and out of working position between the end faces of either of said pair of swinging switch beams and the end face of the continuing main line track beam, said retractile gate having substantially the same beam cross section with rails for truck support as the aforesaid switch and other track beams thereby to establish track continuity, and means replaceably retracting the gate from said working position to release the switch beams for selective positioning.
Claim 2
Dependent Claim
155 words
An articulated self-aligning switch for elevated monorail track, and including; a pair of swinging switch beams with bearing means pivotally mounting the switch beams to the terminal ends of a main line track beam and a lateral track beam respectively, link means coupling the pair of switch beams to swing together and in spaced relation to each other and into and out of alignment with a continuing main line track beam, a retractile gate secured to ways and shiftable into and out of working position between the end faces of either of said pair of swinging switch beams and the end face of the continuing main line track beam, said retractile gate having substantially the same beam cross section with rails for truck support as the aforesaid switch and other track beams thereby to establish track continuity, and means replaceably retracting the gate from said working position to release the switch beams for selective positioning.
Claim 3
Dependent Claim
37 words
The switch for elevated monorail track as set forth in claim 1, wherein the end face of the continuing main line track beam is angularly disposed to pass the said terminal end of the lateral track beam.
Claim 4
Dependent Claim
41 words
The switch for elevated monorail track as set forth in claim 1, wherein the said ways are upwardly reclined away from the end faces of the swinging switch beams for withdrawal of the retractile gate when out of said working position.
Claim 5
Dependent Claim
67 words
The switch for elevated monorail track as set forth in claim 1, wherein the end face of the continuing main line track beam is angularly disposed to pass the said terminal end of the lateral track beam, and wherein the said ways are upwardly reclined thereon away from the end faces of the swinging beams for withdrawal of the retractile gate when out of said working position.
