Voros, St. Charles, Mo., assigner to ACF Industries, Incorporated, New York, N.Y., a corporation of New Jersey Filed Mar. 27, 1967, Ser. No. 626,102 U.S. Cl. 52-53 6 Claims Int. Cl. B61d 17/12; E04c 1/39; E04d I/30 ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION Conventional steel roofs are composed of multiple steel panels extending transversely of the car. The steel panels may be subassembled by butting the transverse anges, laying a steel seam cap over the abutting llanges, and then fastening the abutting flanges with a row of rivets. The subassembled roof structure is then applied to the box car superstructure. In the event of relatively small variations in dimensions, the metal roof structure may be stressed to conform to the intertting car structure. Prior U.S. Patents Nos. 1,450,243 and 1,461,721 show overlapping metal panels which are riveted together and are in nested relation only adjacent the eaves or upper sides of the box car.
DESCRIPTION OF INVENTION The roof structure of the present invention comprises a plurality of molded plastic panels to provide -a lightweight roof structure. As an example, a conventional steel roof for a fty (50) foot box car has a weight of around twenty-two hundred (2200) pounds while the roof structure of the present invention weighs only around eight hundred iifty (850 pounds). Such a weight reduction permits a greater capacity of lading in the box car. Adjacent lapping panels provide a generally uniform reinforcing box-shaped section extending transversely of the car for the full width of the car to reinforce the roof structure. The adjacent panels are adhesively bonded to each other at each side of the box-shaped section thereby providing a double seal against water leakage.
To receive the underlapping marginal portion of one of the adjacent panels, a recessed portion or indentation is provided on the underside of the overlapping panel adjacent the inner side of Va reinforcing channel-shaped rib for the full width of the car. As each panel is of a generally uniform thickness, a stepped or raised portion is provided on the outer surface of the overlapping panel adjacent the channel-shaped rib. The indentation permits a relatively smooth inner surface and a relatively tight fit at the side plate structures of the box car. In addition, the amount of lapping on each pair of panels may be varied to allow for a total car length variation as much as around seven (7) inches for a car of around fty (50i) feet in length without any change in panel design.
Another feature of this invention is in the manner of securing the roof structure. The plastic panels are not predrilled and upon positioning of the roof structure on 3,429,083 Patented Feb. 25, 1969 the box car, a template is attached at the side plate structure and holes are drilled in the plastic panels in alignment with the predrilled holes in the side plate structures thereby eliminating any necessity for prestressing the panels and reducing the possibilities of oversized holes and resulting water leakage.
The method of forming and securing the roof structure of the present invention comprises rst preassembling two roof halves, each half comprising one metal end panel and a plurality of plastic panels, positioning a center key panel on the car, and then positioning the -preassembled roof halves of the center panel. The center panel permits a car length adjustment of around two (2) inches for variations in car lengths.
The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

FIGURE 13 is a section taken generally along line 13-13 of FIGURE l2.
`Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.
Referring now to the drawings for a better understanding of this invention, a railway box car is generally indicated 10 having sides 12 and ends 14-- As shown particularly in FIGURES 4 and 5, side 12 includes side posts 16 and side panels 18 secured thereto. A side plate 2l) extends longitudinally along each side 12 Iand has an outwardly extending upper flange 22 to support the roof structure generally indicated 24 and comprising the present invention.
Each roof subassembly 2S comprises a metal end panel and a plurality of molded plastic panels 32. Each molded plastic panel 32 is generally identical and of a generally uniform thickness. Referring particularly to FIGURES 7, 8, and 9, each panel 32 has a channelshaped rib or reinforcement 34 extending transversely of the railway car 10. Rib 34 has tapered or sloping ends 35 and is of a uniform cross section between ends 35, A free lip or flange 36 extends outwardly from the outer side of rib 34. Formed adjacent the inner side of each rib 34 on the inner surface of panel 32 is an indentation or recessed portion 3S. Recessed portion 36 forms a stepped or outwardly extending projection 40 on the outer surface of panel 32. Main body portion 42 of panel 32 includes a plurality of relatively small projecting ribs 44 to reinforce body portion 42. A smooth marginal side portion 46 of body portion 42 adjacent ribs 44 is .adapted to be positioned beneath a rib 34 of an adjacent panel 32 and a smooth marginal end portion 48 is adapted to fit against upper flange 22 to provide a relatively tight fit therewith. To secure two molded plas tic panels 32 together and referring to FIGURES 6 and 6A, a suitable adhesive 47 such as a polyester or epoxy adhesive, is brushed onto the contacting surfaces of marginal side portion 46 of one panel and side portion 46 is then fitted within indentation 38 of an adjacent panel. The panels are suitably clamped together until the adhesive cures which may be twenty-four hours or more dependent on the particular adhesive employed and the ambient temperature. FIGURE 6A indicates the adjustment which may be made between overlapping panels 32 to vary the length of the roof structure by varying the amount of overlap between adjacent panels 32.
To assemble the roof structure comprising the present invention, the two roof halves or subassemblies 28 are each preformed from a plurality of molded plastic panels 32 and one metal end panel 30. Key panel 26 is then secured to side plates 20 centrally of the length of the car. Then, the two roof subassemblies 28 are placed over center panel 26 as shown particularly in FIGURES l2 and 13 and suitable openings are drilled in panels 32 in alignment with predrilled openings in flanges 22 of side plates 20. Bolt and nut combinations 29 secure subassemblies 28 to side plates 20. Nut and bolt combinations may be employed, if desired, to secure panels 32 to key panel 26 to avoid curing times normally required for adhesive securing means. In such event, a suitable sealing material could be placed between panels 26 and 32 to provide water tightness.
Molded plastic panel 32 may, for example, be formed of a reinforced fiber glass material. Other suitable thermoset or thermoplastic resins may be employed, such as polyesters, phenolics, epoxies, silicones, polyethylenes, and polypropylenes. Reinforced plastics usually include fibers of glass, asbestos, sisal or cotton in woven or nonwoven form. Glass fibers are most widely used with polyesters, phenolics and epoxy thermosets.
From the foregoing, it is understood that a lightweight roof:` structure for a railway box car is provided which may decrease the weight of a fifty foot box car around fourteen hundred pounds. The roof structure is formed from a plurality of molded plastic roof panels 32 which are arranged in an overlapping relation to provide a box-shaped reinforcement and a length variation of several inches, if desired, without changing the panel design. The panels 32 are secured to each other in a nested relation so as to provide a flush or smooth inner surface for fitting on side plates 20. Further, the panels have a double seal at the connecting box-shaped reinforcement to minimize any water leakage.
In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results obtained.
As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
