Embodiment Construction

[0022]Referring now to FIGS. 1-5, a convertible railway car hatch cover is generally designated 10 and comprises an exterior shell cover 12, a mounting ring 28, and a gasket 30. The exterior shell cover 12 is generally round in the horizontal direction and dome-shaped in the vertical direction with respect to the railcar, but the exterior shell cover 12 can be any other shape as well. The exterior shell cover 12 has an outer-side 14 and an under-side 16. The exterior shell cover 12 is preferably molded from a polymeric material, but it can also be made from a metallic material. Hinges 18 connected to the outer-side 14 of the exterior shell cover 12 pivotally connect the convertible railway car hatch cover 10 to a set of hatch hinges 34 on top of a railway car (not shown). The hinge allows the exterior shell cover 12 to rotate up to 180 degrees with respect to the closed position.

[0023]A gasket 30 is mounted to a mounting ring 28 by pressing the gasket 30 into the mounting ring 28, a...

Abstract

A railway car hatch cover includes an exterior shell cover, a gasket, and a mounting ring. The exterior shell cover has an outer-side and an under-side. The gasket is a vented gasket or a non-vented gasket, and the gasket is mounted to the mounting ring. The mounting ring is secured to the under-side of the exterior shell cover. The mounting ring is removable, and the gasket is replaceable with a second gasket. The second gasket can be vented or non-vented. The mounting ring is reinstallable on the under-side of the exterior shell cover. The replaceable gasket allows a single hatch cover to function as a vented hatch cover or a non-vented hatch cover depending on the type of gasket installed.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates generally to railway car hatch covers, and more particularly to a convertible railway car hatch cover.[0002]This invention is applicable to railway car hatch covers. On covered hopper railway cars, each car has a series of hatches on top of the car that allow the railway cars to be filled from the top with various commodities, such as plastic pellets, flour, grain food products, and the like. The hatches also allow access into the car for maintenance and an opening for venting purposes. After the railway car is loaded, a hatch cover is secured over each hatch to prevent outside substances from contaminating the goods in the car, and also to prevent spillage and secure the goods or substance inside the car for transportation. A gasket is used in each hatch cover to create an air-tight seal. When it is time to unload a loaded railway car, a suction device can be connected to a fitting on the bottom of the railway car, and the car ...
