I claim: l

v l. Thecombin'ation with end frame members and belt rails of a railway car, of a metal end structure comprising an end sheet having flanges overlapping the sides of the car, anchoring members for said end sheet on the inside of the carsecured to said belt rails and extending through and secured to said end sheet.

2. The combination with the end frame .membersand belt rails of a railway car, of .a metal end structure comprising an end sheet having flanges overlapping the sides 50 of the car, anchoring members for said end sheet on the inside of the car secured to said belt rails and extending through and secured to said end sheet, and angular members on the outside of the car secured to the belt rails 5E and having flanges which bind the sheet against the end frame of thecar.

3. The combination with the end frame members and belt rails of a railway car, of

a metal end structure comprising an ended sheet having flanges overlapping the sides of the car, angular members on the outside of the car secured to said belt rail and h aV-' ing flanges which bind'the sheet against the end frame of the car,.and anchoringmembers on the inside of the car secured to said belt rails and extending through said end sheet and through the end flanges of said angular members. 4. The combination with the ridge pole of a railway car, of an end structure comprising a corrugated metal end sheet,'and a vertically extending reinforcing member secured at intervals to said end sheet and at-' tached to said ridge pole.

5. The combination with the upper and lower end .frame members of arailway car,

of a sheet metal corrugated end structure horizontal corrugations, and a vertically extending reinforcing member secured at intervals to said end sheet and attached to said upper and lower end frame members. 'WALTER P. MURPHY. Witnesses: v
