SHEET-METAL END STRUCTURE FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed November 25, 1912. Serial No. 733,369.

To all whom it may concern:

Be it known that I, WALTER P. MURPHY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sheet-Metal End Structures for Railway-Cars, of which the following is a specification.

My invention relates to a sheet metal wall structure for railway cars, more particularly for the end wall of the car, and the primary object of the invention is to provide a structure of this sort consisting of one or more sheet metal panels having corrugations which run to opposite edges of the panel, this feature facilitating the pressin of the corrugations; and, further, to provi e pairs of attaching members for the panel or panels, one pair at each of the edges of the panel to which the corrugations run, between which said edges are arranged and to which they are attached, whereby the corrugations form, in eflect, restrained beams, giving the panel great strength and rigidity.

The invention is illustrated in certain preferred embodiments in the accompanying drawings, wherein Figure 1 is an elevation of the superstructure of a railway box car provided with a corrugated sheet metal end wall constructed in acordance with my invention.

Figs. 2 and 3 are views, in perspective, of one pair of attaching members for the panels, Fig. 2 being the outer member and Fig. 3 the inner member, these figures being on a smaller scale thanFig. 1.

Fig. 1 is asectional plan, on an enlarged scale, on line '44 of Fig. 1.

Fig. 5 is a vertical sectional view on line 55 of Fig. 1.

Fig. 6 is a view corresponding to Fig. 4., illustrating a modification, and

Fig. 7 is a vertical sectional view on line 77 of Fig. 6.

Like characters of reference designate like parts in the several figures of the drawings.

Referring first to Figs. 1 to 5, inclusive, theend structure consists of an upper corrugated panel 10, a lower corrugated panel 11, and at each side of the car a pair of attaching members 12.(Fig. 3) and 13 (Fig. 2), the members 12, 13 being preferably an gular in cross-section. The panels are formed with corru ations 14 which run to the vertical edges 0 the panels. Preferably, one flange of each of the angular attaching member 12 overlapping the e panels on the outside. Panel 10 overlaps panel 11 and is secured thereto by a line of rivets 18. The attaching members have flattened portions 19, 20 so that they fit the panels closely at these places. Preferably the lower panel has an inturned flange 21 which is secured by bolts 22 to the end sill 23 of the car, the flange intervening between the end sill and the flooring 2 1. The upper edge of panel 10 is secured to the end plate 25 by means of bolts 26 which extend through the fascia plate 27. The edges of the panels are secured to the corrugated flanges of the panels by means of rivets 28,29.

A modification is shown in Figs. 6 and 7. In this construction the corrugated panels, the lower panel 11 being shown, are secured between pairs of angular corrugated attach ing members 12*, 13 the flat flanges of which lie on opposite sides of the corner post 16 and are secured thereto by bolts 15*. I have also shown a flat sheet steel lining plate 30, the vertical edge of which is secured to the panel and to the attaching members by rivets 28 The lining plate may be also secured to paneLll at the points intermediate the sides of the car by rivets 31. I do not claim the lining plate in this application. The other parts of the car construction shown in Figs. 6 and 7, and not described, are the same as corresponding parts in the construction of Figs. 1 to 5, inclusive, and are given corresponding reference numerals.

A car end of either of the constructions above described can be economically manufeatured. The pressing of the corrugations is simplified by having the corrugations run to the edges of the sheet. The pressing operation can be carried on in the ordinary corrugating machine. The construction is extremely strong and rigid, due to the fact that the corrugations, which function as lbs beams, are fixed between rigid attaching members, namely, members 12 and 13, or 12"' and 13, as the case may be. The corrugations are, in eflect, restrained beams and function as such in transmitting to the framing of the car the load of shifting cargoes.

I claim:

1. The combination with a railway car, of an end structure comprising an end sheet formed with corrugations which extend to the edge of said sheet, a pair of attaching members provided with flanges secured to the car body and with corrugated portions between which the corrugated edge of said end sheet is secured.

2. The combination with a railway car, of an end structure comprising an end sheet formed with corrugations which extend to the edge of said sheet and merge one into the other, a pair of angular attaching members provided with flanges secured to the car body and with corrugated portions between which the corrugated edge of said end sheet is secured.

3. The combination with the corner posts of a railway car, of an end structure comprising an end sheet formed with horizontal corrugations extending to the edges of said sheet and merging one into the other, and a pair of attaching members at each side of the car provided with flanges secured to opposite sides of said corner posts and with corrugated portions between which the corrugated edges of said end sheet are secured.

4. The combination with the corner posts of a railway car, of an end structure for the car comprising corrugated sheet metal panels extending across the car from one corner post to the other, and a pair of attaching members, angular in cross section, secured to each of the corner posts between which the outer edges of said panels are fastened.

5. The combination with the corner posts of a railwaycar, of an end structure for the car comprising corrugated sheet metal panels extending across the car from one corner post to the other, and a pair of attaching members angular in cross section secured to each of the corner posts on opposite sides thereof between which the outer edges of said panels are fastened.

6. The combination with the corner posts of a railway car, of a corrugated sheet metal end structure for the 'car having along its vertical edges means providing two pairs of attaching flanges which stand at right angles to the plane of the end and are adapted to overlap and be secured to opposite sides of the corner post in each case.

7. A sheet metal end structure for a railway car, comprising a sheet metal panel extending across the end of the car and formed with corrugations which run to opposite edges of the panel, and pairs of angular attaching members, one pair at each of said edges between which the said edges are fastened.

8. In a railway car, a sheet metal panel having corrugations running to opposite edges thereof, and pairs of attaching members, one pair at each of such edges which overlap the said edges on both sides thereof, to which said edges are fastened so that the corrugations form, in efl'ect, restrained beams.
