Description

Jan. 10, 1967 A. G. DEAN CORRUGATION END FINISH Filed Aug. 12, 1964 INVENTOR. ALBERT G. DEAN ATTORNEY United States Patent 3,296,766 CORRUGATION END FINISH Albert G. Dean, Narberth, Pa., assignor to The Budd Company, Philadelphia, Pa., a corporation of Pennsylvania Filed Aug. 12, 1964, Ser. No. 389,015 3 Claims. (Cl. 52-625) This invention relates to corrugated railway car bodies and, more particularly, to an improved corrugation end finish.
One of the objects of the invention is to provide an improved corrugated finish wherein the flattened ends of the corrugations have sharp edges that are shielded to protect people and articles against injury or damage due to the sharp edges.
Another object is to provide a corrugation end finish wherein the edges of flattened corrugations are shielded by means which additionally increases the strength and rigidity of the structure and improves the appearance thereof.
Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing wherein:
FIG. 1 is a side elevational view of a portion of a side loading rapid transit car embodying the invention;
FIG. 2 is an enlarged view, with portions removed, of the detail enclosed in reference box 2 of FIG. 1;
FIG, 3 is an enlarged sectional view along lines 3-3 of FIG. 2;
FIG. 4 is an enlarged perspective detail view with portions removed.
Referring now to the drawing, there is shown, in FIG. 1, a portion of a side loading rapid transit car having a car body provided with a plurality of corrugated panels 11. As illustrated, the panels are located on the side walls, the end walls, and the roof of the car body. Since, as indicated above, one of the objects of the invention is to protect people against injury by sharp edges on the ends of the corrugations, the invention is shown as applied only to those panels, namely the side wall panels and end wall panels, which are subject to bodily contact.
With reference to FIGS. 2-4, a longitudinally corrugated panel 11, on the side wall of car body 10, has a vertical edge that lies outboardly of a door post 12. Sandwiched between this edge of panel 11 and post 12 is a stiffener and shield member 13. Panel 11, post 12 and member 13 are joined by spot welding and the resultant joint is sealed by a conventional, commercially available spot-weld or weld-through sealer 14, the sealer being not shown in FIG. 4 for clarity of illustration.
Panel 11 has a plurality of corrugations formed, between their ends, by bottom walls 15, side walls 16 and top walls 17. The ends of the corrugations are flattened by pressing or mashing the top wall down towards the bottom wall so as to fold the side wall therebetween. Thus, as indicated at 18, the corners of the end of each corrugation have a thickness slightly greater than three "ice times the thickness of the sheet metal of the panel. edge thus formed is relatively sharp.
Member 13 comprises a flat portion 20 having an inner edge 21 co-terminous with the adjacent edge of post 12 and an outer edge which extends under the edge of panel 11 and is bent arcuately over on itself to form a bead 22 of a diameter d, measured normal to the plane of flat portion 20, greater than the thickness of the corrugations measured at 18 by an amount sufliciently great to prevent bodily contact with the sharp edges of the corrugations. Bead 22 nests against or abuts and extends alongthe sharp edge of panel 11 and stiifens the combination against bending along longitudinal lines.
Sealer 14 is applied, during assembly, between member 13 and panel 11 and post 12, and the panel, member 13 and post 12, are then connected by spot welding bottom walls 15 to the other members, as shown in the drawing. Preferably the panel, member 13 and post 12, are formed of a stainless steel to provide high strength to weight ratio. By way of a more specific example, panel 11 can be of .025 inch thick, type 301, quarter-hard stainless steel, and member 13 can be of a .018 inch thick sheet of similar material wherein bead 22 has a diameter d in the order of Ms".
While the above description is with reference to joining the panel at the door post, it will be apparent that the other edges of the panels can be joined in a similar manner to the underlying or adjacent structural members. It is to be understood that while only a single embodiment has been shown, changes can be made without departing from the scope of the invention as defined in the appended claims.
I claim:
1. In combination, a panel having a plurality of corrugations extending .in a given direction, ones of said plurality of corrugations being flattened along their end portions and terminating along an edge transverse to said given direction, a member having a flat portion underlying said panel beneath said flattened portions of said corrugations thereby stiffening said panel against bending between corrugations, said member having a marginal edge portion extending upwardly from said flat portion to overlie the same and to abut said flattened corrugations terminating along said transverse edge.
2. The combination of claim 1 wherein said marginal edge portion extending upwardly from said flat portion is of arcuate cross-section.
3. The combination of claim 1 wherein said ones of said plurality of corrugations flattened along their end portions are multiples of a single thickness of material and wherein said marginal edge portion of said member extends above a distance greater than said multiples of thickness of material.
