Abstract
Support assembly for joining and insulating a plurality of electrically-charged rails adaptable for transmitting electrical current to a trolley or like vehicle and comprising an insulative member surrounding each of the conductive rails, with adjacent rails and corresponding insulative members being joined at spaced junction hoods for ensuring complete insulation of the rails at all operating temperatures.
Claims16
An assembly for joining and insulating a plurality of electrically-charged rail sections to provide electrical power to a trolley or the like and comprising:
- a plurality of insulative members each enclosing a surface portion of a separate rail section with each insulative member having an axial length which is less than an axial length of a respective rail section enclosed by said insulative member to allow for relative thermal expansion or contraction;
- a plurality of spaced, junction hood assemblies arranged for supporting end portions of adjacent rail sections and adjacent insulative members;
- wherein each of said junction hood assemblies is formed from a single piece and include opposed open end portions, each of which is closed by a capping member which is pivotally hinged to each of said junction hood assemblies and which is pivotable into said open end portion;
- each of said junction hood assemblies further including means for allowing movement of said insulative members while ensuring insulative coverage of portions of said rail sections extending between adjacent junction hood assemblies.
An insulated, electrically-charged rail assembly capable of transmitting electrical current to a trolley or the like, and comprising:
- a plurality of adjacently disposed rail sections arranged in end-to-end relationship to one another, with a plurality of said rail sections each including at least one leg member having a projection extending outwardly therefrom;
- a plurality of adjacently disposed insulative sections, each partially enclosing a separate rail section, wherein each rail section is longer than its partially enclosing insulative section to allow for thermal expansion or contraction of each pair of adjacently disposed insulative sections;
- a separate junction hood assembly having opposite end portions overlapping a pair of said adjacently disposed rail sections as well as overlapping the insulative sections partially enclosing said pair of rail sections, with the opposite end portions of said junction hood assembly each including a curved leg portion and a confronting projection extending outwardly from each of said pair of rail sections;
- and
- substantially H-shaped engagement means mounted on each insulative section for slidably engaging said leg portion and said confronting projection to properly align said junction hood assembly relative to said rail section while allowing relative thermal expansion between said rail and insulative sections.
