CORRUGATED WALL PLATE.
Application filed June 7,
The invention resides in forming corrugations or embossments in a metallic plate so as to increase its strength to resistexterior loads applied upon it. By forming said corrugations or embossmentsintegral with the plate, considerable fabrication of other parts and riveting is eliminated, and furthern'iore, the ultimate weight of the structure is retained at a minimum.
Such integrally reinforced plates are especially adaptable for end walls of railway freight cars where the shifting of the lading causes severe impacts against the end wall. These integral reinforcements also resist the tendency of the plate to buckle, due to the torsional and weaving movements of the car in service. Such a plate may'alsohe used for the floor or roof of a railway car.
Such corrugations or embossments are mechanical beams and can be considered and calculated as such.
lVhen a car is loaded with sand, grain, charts or other plastic material it imposes an equally distributed load upon these beams. There are two ways of designing a beam to carry an equally distributed load so that its strength at any given point will be coinmensurate with the bending moment at that point; in other words, so that the libre stress will be the same at any plan-e crossing the beam. Y
First: 1f the beam is maintained at an `equal height throughout its length its width must vary so that the contour of the sides form two parabolas having their vertices at the middle of the beam and their bases coincident.
Second: If the beam is maintained at an equal width throughout its` length its height must vary so that its contour assumes a semi-elli pse.
My invention resides in forn'iing an integral embossmen't in a plate .so that the height and width are proportioned in .accordance with the known theories covering beams of equal strength throughout for equally distributed loads.
,Another object of the invention is to provide an embossment in a plate which can 1923. Serial No. 643,934.
readily be formed therein by a pressing operation and which would cause very little wear on the dies as there is very little drag of the metal over the dies.
In the drawings:
Figs. l and 2 show elevation and plan views respectively of my embossment wherein the height is maintained substantially the same throughout its length. I
Fig. 3 shows a section on line 3-3 of Fig. 2.
Fig. 4 shows a sectionv on line 4 4 of Fig. 2.
Fig. 5 shows a section on line 5-5 of Fig. 2.
Fig. 6 shows an end view of a railway car with my invention applied thereon.
Numeral l designates a fiat plate having an embossment 2 pressed integrally therein which has a constant height substantially throughout its length and is provided with terminal portions 3 which merge into thev plane of the plate.
I claim t l. A metallic plate having a corrugation formed therein of constant height and having its width vary so that thecontour of the sides forni two parabolas with their vertices at the middle of the beam and their bases coincident, so that said corrugation is of uniform strength throughout its length for an equally distributed load.
2. A metallic plate having a corrugation formed therein of constant height .and havits width vary yso that the contour of the sides form two parabolaswvith their vertices at the middle of the beam and their bases coincident, so that said corrugation is of uniform strength throughout its length for an equally distributed load, said corrugation having terminal portions merging into the plane of the plate.
