Patented Sept. 24, 1929 UNITED STATES ,PATENT OFFICE GARTH G. GILPIN, OF RIVERSIDE, ILLINOIS, ASSIGNOR TO UNION METAL PRODUCTS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION 0F DELAWARE CORRVUGATED METALLIC PLATE Application mea February 9,1928. sei-iai No. 253,1sa
My invention relates to the construction of vrailway cars, and more particularly to wall structures made of one or more metallic plates or panels formed with integral reinforcing, stiening and bracing embossments or corrugations. Car wall structures frequently require small doors therein for loading lumber, rails or other similar long material or for the installation of ventilators When the car is used to convey perishable lading, such as fruits, etc. Railway stock cars require openings therein for loading sheep, hogs, or oth er small animals. When the wall or other car structure is made of a corrugated metallic plate it is desirable to form the corrugated or embossed metallic plate so that the cutting of the door opening therein will not reduce the strength of the corrugations, or at. least, will reduce their strength a very small amount.
The object of my invention is to provide a door opening in a corrugated or embossed metallic plate and to so form the corrugations or embossments that their strength will not be materially reduced.
Another' object is to provide a door opening in a corrugated or embossed metallic plate and form the corrugations or embossments so as to be relatively rigid adjacent the door opening and relatively resilient adjacent the frame members of the car to which the metallic plate is secured.
Another object of the invention is to provide a panel for a door opening in a metallic plate, which plate is provided with a plurality of corrugations, some of which merge into the panel and others of which extend continuously across the plate to opposite sides thereof.
In the drawings:
Fig. 1 is a typical application of my structure as used for an end wall of a railway boX car.
Fig. 2 is a section on line 2 2 of Fig. 1.
Fig. 3 is a detail of a typical metallic plate.
Fig. 4 is an end view of Fig. 3.
Figs. 5 to 9 inclusive are sections on lines 5 5 to 9 9 respectively of Fig. 3.
Fig. l() is a fragmentary section showing the application of a typical Idoor frame.
(such as shown in Fig. l0) or door may be used with my construction. The drawings, however, show a slidable door l2 mounted in ak four sided cast metal door frame. The door frame is preferably of such form and construction and is secured to the metallic plate so as to transmit any horizontal loads imposed thereon to the oppositely disposed embossments; or in other words, to make the aligned embossments (such as 13 and 13) in effect, a continuous beam from one edge to the opposite edge thereof.
The plate is formed with a plurality of pri mary corrugations or embossments 2O which spring from the opposite sides of the panel 7 and which preferably decrease in width and decrease in depth and terminate into the plate adjacent the opposite edges of the plate or adjacent the frame members of the car (corner post 3 3, for instance) to which the plate is secured. Terminations 21 may be provided if desired. The plate is also provided with secondary corrugations or embossments 22 which spring from the plate adjacent the panel and terminate into the plate adjacent the opposite edges thereof or adjacent the frame members of the car to which the plate is secured and may Valso be provided with terminations 23 if desired. The ends of the primary corrugations` or embossments are substantially equal in width to the outer ends of the secondary corrugations or embossments and are spaced apart dis yances equal to their widths. The ends of the primary and sec.- ondary corrugations and cmbossments, as well as the portion of the plate between the corrugations and embossments, are formed with a curved contour so as toform asinuous and resilient structure. (See Fig. 9.) These secondary corrugations or embossments preferably terminate into the plate in alignment with the primary corrugations or embossments. The portion of the plate adjacent the raised panel (see Fig. 8) is formed with embossments 2O preferably spaced apart distances equal to their width and the embossments preferably have arcuate (with large radii) tops 2T and the portions of the plate 28 between the embossments are also preferably arcuately formed (with large radii) and are preferably deeper (28) than the secondary corrugations or embossments 22, whereby a structure is provided which is relatively stronger and relatively more rigidj than the section ofthe plate (Fig. 9) through the ends of the divided port-ions 23 of the embossments.
The plate is also preferably formed with a eorrugation or embossment 30u81 en one or both sides of the panel which decreases in width and decreases in height toward their opposite ends and terminate into the plate preferably in alignment with the primary and secondary corrugations or embossments. These corrugations or embossments preferably terminate adjacent the terminations of the primary and secondary corrugations or embossments and are equal in width thereto and spaced therefrom a distance equal to their width so as to form a sinuous resilient structure (see Fig. 9) furthermore, the middle of these corrugations or einbossments correspond in contour to the corrugations or embossments adjacent the panel to co-operate to form a contiguous and sinuous configuration.
Corrugated metallic plates, such as shown in the drawings, are formed between dies mounted in the platens of a reciprocating press and it has been found that in forming such a1 flat panel, as herein shown and described, that the metal wrinkles and is deformed so that when a part of the panel is cut out to make the door opening` that the metal so cut out cannot be used for other purposes without being straightened. l overcome this objection by forming a continuous web 33 around the portion of the plate to be out out for the aperture which eliminates the wrinlrling and bending so that after the plate is pressed the portion of the plate cut out for the aperture is not scrapped, but in fact, is used to form the door (l2) for the individual plate. A flat portion 84 isleft between the continuous web 33 and the edge of the door opening for attachment of a door frame.
The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.
In my co-pending application Serial No.
253,182, filed February 9, 1928, I have disclosed and claimed certain features which are disclosed but not claimed in this application.
