Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
A railway passenger vehicle having a body unit riding on and supported by spaced wheel and truck units, said body unit including spaced end door members and spaced transversely extending end sills, a corridor passenger channeling device for guiding persons between adjacent vehicles, the improvement comprising: an end sill including an extension portion extending horizontally outwardly of the end sill, a buffer plate assembly pivotally attached to said end sill extension and having a contacting face portion adapted to contact an associated buffer plate of an adjacent passenger vehicle, passenger safety gate means including guide members mounted on said buffer plate assembly and spaced each side of said car door, said guide members having portions extending upwardly of said pivotable buffer plate assembly and spaced rearward of the contacting face portion of the buffer plate assembly to thereby provide a spacing between adjacent guide members of coupled cars.
