Abstract
A wall lining sheet, particularly, but not exclusively, for lining the interior end walls of freight railway cars. The wall lining sheet comprises a metal sheet having a plurality of spaced-apart attachment tabs each defined by a configured slot extending through the sheet. Each of the tabs has a bendable free end portion whereby the bendable free end portion may be displaced outwardly from the plane of the sheet. The wall lining is particularly useful in relining the interior surface of corrugated end walls of freight railway cars after the end wall has been deformed and reshaped substantially to its original state.
Claims9
A wall lining sheet comprising a rigid sheet having a plurality of spaced-apart bendable attachment tabs disposed in the plane of said sheet and each defined by a configured slot extending through said sheet, said sheet being free of support adjacent said tabs and each said tabs having a bendable free end portion and transverse opposed side edges free of said sheet whereby said bendable free end portion may be displaced outwardly from the plane of said sheet without deforming said sheet for securement of said sheet to a backing structure having an irregular outer plane, said securement being effected by a weld formed between said tabs and said outer plane through an opening formed by said configured slot after deformation of said tabs to an adjacent portion of said irregular plane.
In a railway car comprising corrugated end walls each having an outer face with elevated ridges, the improvement comprising a wall lining sheet secured over an inner face of each said end walls, said wall lining sheet comprising at least one metal sheet having a plurality of spaced-apart bendable attachment tabs disposed in the plane of said sheet and each defined by a configured slot extending through said sheet, each said tabs having a bendable free end portion and transverse opposed side edges free of said sheet whereby each said tabs is displaceable from its normal plane without deforming the sheet, at least some of said tabs being welded to said elevated ridges of said outer face of said end walls with at least some of said tabs bent outwardly of said sheet towards said inner face to compensate for irregular spacing between said outer face of said wall lining and said elevated ridges of said inner face of said corrugated end walls, said weld being formed between said tabs and said elevated ridges through an opening formed by said configured slot after deformation of said tabs to an adjacent portion of said elevated ridges.
