Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
186 words
Vehicle switching apparatus comprising: transport track means including an upstream section, diverging first and second downstream sections and a junction section at the confluence of said upstream and downstream sections; inverted channel means secured to said track means; switching guide surface means mounted on said channel means at said junction section and including a first stationary run associated with vehicle transport along said first downstream section and a second stationary run associated with vehicle transport along said second downstream section, each of said runs providing an uninterrupted guide surface from said upstream section, through said junction section and to the associated downstream section; and vehicle carriage means including support roller means engaging said track means, first and second antifriction means and selectively operable drive means for directing a said antifriction means into directionally switching engagement with a selected stationary run, each of said runs comprising a trolley surface defining a running bed for a said antifriction means and flange means extending away from said trolley surface and projecting from a wall of said channel means for positionally retaining the antifriction means relative to the trolley surface.
Claim 2
Dependent Claim
186 words
Vehicle switching apparatus comprising: transport track means including an upstream section, diverging first and second downstream sections and a junction section at the confluence of said upstream and downstream sections; inverted channel means secured to said track means; switching guide surface means mounted on said channel means at said junction section and including a first stationary run associated with vehicle transport along said first downstream section and a second stationary run associated with vehicle transport along said second downstream section, each of said runs providing an uninterrupted guide surface from said upstream section, through said junction section and to the associated downstream section; and vehicle carriage means including support roller means engaging said track means, first and second antifriction means and selectively operable drive means for directing a said antifriction means into directionally switching engagement with a selected stationary run, each of said runs comprising a trolley surface defining a running bed for a said antifriction means and flange means extending away from said trolley surface and projecting from a wall of said channel means for positionally retaining the antifriction means relative to the trolley surface.
Claim 3
Dependent Claim
26 words
Vehicle switching apparatus according to claim 1 wherein said flange means includes spaced first and second flange members disposed at opposite edges of said trolley surface.
Claim 4
Dependent Claim
43 words
Vehicle switching apparatus according to claim 1 wherein each of said runs comprises spaced opposed restraining flanges and a trolley surface defining a running bed for a said antifriction means between said flanges, said trolley surface being disposed laterally of said track means.
Claim 5
Dependent Claim
42 words
Vehicle switching apparatus according to claim 1 wherein each of said runs comprises spaced opposed restraining flanges and a trolley surface defining a running bed for a said antifriction means between said flanges, said trolley surface being pendant from said track means.
