ABSTRACT:
A diaphragm assembly (10) is provided around the doors (11) of adjacent railway cars (12) and together adjacent diaphragm assemblies (10) enclose the passageway between adjacent railway cars (12). Each diaphragm assembly (10) includes a mounting plate (15) having vertical sections (17, 18) at the side of door (11) and an arch portion (19) above door (11) mounted to a car (12). The mounting plate (15) is of a predetermined lateral width and carries side portions (22) of a flexible membrane (21). A bridge portion (23) of flexible membrane (21) extends between side portions (22) and is attached to a face plate (25) which has vertical sections (26, 27) at the side of door (11) and an arch portion (28) above door (11). The face plate (25) has a predetermined lateral width greater than the width of mounting plate (15). Face plates (25) of adjacent cars ( 12) are adjacent to each other and a seal assembly (40) may be provided between the arch portions (28) thereof to prevent liquid from entering the passageway. At the bottom of the diaphragm assembly (10), a sill membrane (70) is attached to a sill plate (29) which is mounted between the vertical sections (26, 27) of the face plate (25). The sill plate (29) is attached to push rods (51) of the car (12) by a connector assembly (50) including bushings (57, 60) which minimize the noise of the connection. A walk plate (80) is hingedly connected to the sill plate (29) and is positioned above the sill membrane (70) to provide for ease of passage from one car (12) to another.
