United States Patent O M' 3,119,351 LliNER AND RETAW'R PANEL Michael .1. Ford, Hartsdale, NX., assigner, by mesne assignments, of one-half to international Paper Company, New York, NX., a corporation of New York, and one-half to The Staniey Works, New Britain, Conn., a corporation of Connecticut Filed May 29, 1959, Ser. No. 816,935 3 Claims. (Cl. 10S- 423) This invention relates to a liner and retainer panel, and the invention is particularly useful in connection with the lining of railway boxcars and other freight vehicles.

An object of the invention is to provide a panel which may be secured to the studs or frame on the interior of the freight vehicle while utilizing fibrous board material reinforced to provide a sturdy and readily applied lining wall. A further object is to provide a lining or retainer panel structure of unique construction which may be nailed or otherwise secured to the interior frame of a car while providing a smooth and uniform interior surface for the car. A still further object is to provide a liner structure in which a metal sheet is supported within fibrous walls of a board for supporting the wall and providing a sturdy liner overspace in the freight vehicle wall. Other specific objects and advantages will appear as the specification proceeds.

The invention is shown, in an illustrative embodiment, by the accompanyign drawing, in which- FIG. 1 is a broken vertical sectional view of a railway boxcar equipped with liner material embodying my invention; FIG. 2, an enlarged broken vertical sectional view, the section being taken as indicated at line 2--2 of FIG. 1; FiG. 3, a broken plan view of my liner or retainer panel, portions of the panel being broken away to show the structure thereof; FIG. 4, a transverse sectional detail view, the section being taken as indicated at line 4 4; and FIG. 5, a broken sectional detail view showing a modified form of panel board embodying my invention.

In the illustration given in FIGS. l-4, inclusive, A designates a railway boxcar having a bottom wall 10, a top wall 11, an end wall 12 and side walls 13. The side walls 13 are provided with spaced vertical studs 14. B designates my liner or retainer panel secured to the studs 14.

The panel B, as shown best in FiGS. 2, 3 and 4, com-l prises two corrugated cores and 16 bonded to sheets or liners 17 and 13, respectively. On their inner sides, the cores 15 and 16 are bonded by adhesive to a metal sheet 19. The metal sheet 19 is thus supported resiliently between the corrugated cores 15 and 16 and is adapted to receive nails 2f) or other fastening means when the panel B is secured to the studs 14, as shown best in FIG. 2.

In operation, the installer places a panel B against the studs 14, as shown best in FIGS. 1 and 2, and drives nails, etc. through the board into the studs 14 or other inner frame of the Vehicle. The nail passes through the corrugated cores 15 and 16, liners 17 and 1S, and through the metal sheet or plate 19 so as to firmly clamp the board against the stud or frame. It is found that the inner portion of the corrugated board yields under the nail head so as to be slightly indented, as in a tufting operation, and leaves the inner liner surface 17 substantially even throughout so that the nails are not projecting for engagement with the merchandise carried in the vehicle. At the same time, the metal sheet 19 serves to lock the entire board firmly in position and also provides a reinforcing, weighted carrying support for the portions of the board extending between the studs or over openings in the frame.

The metal sheet 19 may be formed of aluminum, aluminum alloy, light gauge steel, or other metal which provides 3,119,351 Patented dan. 2?, 1964 ICC the necessary support while at the same time receiving the nails for fastening the board to the car frame. It is found that the metal sheet not only provides tensile strength for the board but also, mounted as it is between resilient core bodies 15 and 1e, is effective in cushioning blows from merchandise within the car and in preventing the corrugated board from breaking or tearing under the impact of articles in ordinary shipping conditions. Since the sheet 19 is coextensive with the panel B, the installer can drive the nails 20 readily through the panel and be certain that the nail engages the metal before it enters the stud 14.

ln the modification shown in FIG. 5, the metal sheet 19a is supported between fibers 21, the bers being confined on both sides by the liners 22 and 23. Preferably the fibers 21 are bound together and to the outer liners by adhesive to form a solid fiberboard and the metal sheet 19o provides a metal sheet core for the board.

The panels B may be erected one above the other along the sides of the car, as illustrated in FIG. l, and the adjacent ends may be nailed to form a tight joint, as illustrated best at the top of FIG. 2.

Should one of the panels become damaged, ready repair can be accomplished by cutting out the damaged portion and using the same as a templet for forming a repair segment which can be readily nailed in place. Further, tape can be extended over the adjacent edges of panels or cut portions of panels to provide ready repair.

While, in the foregoing specification, I have set forth a specific structure in considerable detail for the purpose of illustrating the invention, it will be understood that such details of structure may be varied widely by those skilled in the art without departing from the spirit of my invention.

l claim:

1. In combination with a freight vehicle having an inner frame, a board panel secured to said frame and comprising imperforate metal reinforcing means embedded within a fibrous body, and liners bonded to the outer sides of said fibrous body, said body comprising a corrugated core interposed between said frame and means, and nails extending through said panel and into said frame.

2. In combination with a freight vehicle having Vertical studs therein, lining boards nailed to said studs, each board comprising corrugated cores bonded on the outer sides to liner sheets and bonded on their inner sides to a central imperforate metal sheet, said metal sheet being resiliently supported by said cores, the flutes of said cores being vertically disposed.

3. In a retainer panel for lining freight cars, and the like, an imperforate malleable metal sheet sandwiched between a pair of corrugated paperboard members, said sheet and members being substantially coextensive whereby a nail passing through an edge portion of one member for securing said panel to a stud, or the like, also passes through the other of said members and said sheet, each of said members including a corrugated core disposed immediately adjacent said sheet and a paper liner adhesively secured to its associated core on the side thereof remote from said sheet, the flutes of both cores extending in the same direction.
