A hatch cover for railroad car hatch openings has a body member with inner and outer depending circular flanges. The flanges are located so as to span the loading nozzle or coaming of the hatch. The flanges and body portion define a three-sided pocket between them which receives a removable gasket. The gasket is retained in the pocket by a plurality of clips either integrally molded into the lower edges of the flanges or held by fasteners. The clips extend radially toward the opposite flange. The gasket is sufficiently resilient to allow a user to flex the gasket past the clips during installation and removal of the gasket in and out of the pocket. During opening and closing of the cover the clips retain the gasket in the pocket.
bstract Cette invention concerne un couvercle d'ouverture de chargement de wagon marchandises formé d'un corps et de rebords annulaires intérieur et extérieur se prolongeant vers le bas. Ces rebords ont une configuration leur permettant de couvrir complètement l'hiloire ou bordure verticale de l'ouverture de chargement. Les rebords et le corps du couvercle définissent un logement en U adapté pour recevoir une garniture d'étanchéité amovible retenue en place par une série de clips soit moulés à même le bord inférieur des rebords soit montés au moyen de fixations. Ces clips se prolongent radialement vers le rebord opposé. La garniture d'étanchéité se caractérise par une souplesse suffisante pour permettre de la faire passer au-delà des clips à sa mise en place et son retrait. € l'ouverture et à la fermeture du couvercle, les clips retiennent la garniture dans son logement.
