TEMPORARY DOOR CLOSURE Filed March 12. 1959 ATTORNEYS United States Patent 3,063,498 TEMPORARY DOOR CLOSURE Barton H. Ford, Omaha, Nebr., assignor, by mesne assignments, of one-half to International Paper Company, New York, N.Y., a corporation of New York, and onehalf to The Stanley Works, New Britain, Conn., a corporation of Connecticut Filed Mar. 12, 1959, Ser. No. 799,008 6 Claims. (Cl. 160-368) This invention relates to a temporary door closure, and the invention is particularly useful in connection with a grain door and in the forming and installing thereof.
The present invention is a continuation-in-part of my copending application, Serial No. 568,482, filed February 29, 1956, now Patent No. 2,966,213, issued December 27, 1960.
In the fabrication and installation of grain doors, it has been common to secure metal straps through the use of staples, etc., to corrugated board and to provide the straps with spaced holes adapted to receive nails, means being provided for uncovering the straps so that nails can be driven through the openings thereof. In such structures, the entire strap is perforated at spaced intervals and thereby weakened throughout its length, and further it is necessary to provide fold flaps or other means for exposing the straps.
An object of the present invention is to provide a temporary door closure in which imperforate straps are anchored to a door body in a manner for receiving nails driven through the door, indicia lines being provided for indicating the line of nailing. A further object is to provide a door closure equipped with malleable steel straps so secured to the door as to permit effective nailing thereof so that the only holes through the straps are the actual holes made by the driving of the nails. Yet another object is to provide a structure in which the straps are secured by adhesive alone to the door structure by means of waterproof adhesive and anchored firmly in position to receive nails in the installation of the door. Other specific objects and advantages will appear as the specification proceeds.
The invention is shown, in an illustrative embodiment, by the accompanying drawing, in which FIGURE 1 is a broken perspective view of a railway car to which is secured a door enclosure embodying my invention; FIG. 2, a broken vertical sectional view, the section being taken as indicated at line 2-4 of FIG. 1; FIG. 3, an enlarged broken view in elevation of the inner panel of the door containing nail lining indicia; FIG. 4, a detail sectional View, the section being taken as indicated at line 44 of FIG. 3', FIG. 5, a view similar to FIG. 4 but showing a modified form of the invention; and FIG. 6, a detail sectional view, the section being taken as indicated at line 66 of FIG. 5.
The closure is adapted to be secured to a freight vehicle such as a boxcar, truck, etc., so as to serve for a temporary closure during the shipment of granular goods. In the specific illustration given, A designates a boxcar having a door opening provided with a frame A. To the frame is secured a temporary door closure B.
The temporary door closure B may be of any suitable material. In the illustration given, the door comprises an inner liner 10, an outer liner 11, and a central core 12 adhesively secured to the two liners. The corrugated board is scored near the bottom at 13 to permit a bottom flap 14 to be extended inwardly of the door opening. In the illustration given in FIGS. l-4, inclusive, a plurality of straps 15 are secured within the door body B and between the outer liner 11 and the core 12. The strap 12 may be of any suitable material, but I prefer to employ a malle- 3,063,498 Patented Nov. 13, 1962 able steel strap through which nails may be driven to anchor the strap to the door frame A. The door B may be secured firmly in place by the use of a pry-board 16 at the bottom of the door and a headboard 17 at the top of the door. The pry-board provides a protection when the storm doors outside of the frame A are being pried apart in the opening of the storm doors, while the headboard 17 provides a support at the top of the door A for enabling the operator, after installing the door, to escape from the car.
In the modification illustrated in FIGS. 5 and 6, a steel strap 18 is anchored by adhesive directly to the outer ply or liner 11a of the door body B, the corrugated core 12a being bonded to the liner 11a and the inner liner 10a. I have discovered that when the strap 18 is firmly anchored by strong adhesive, and preferably Waterproof adhesive, to the outer liner 11a, it is possible to erect the door B and to nail it securely in position with the nails passing I through the imperforate strap 18. With this structure,
the edge of the strap 18 is visible and the operator can I see where to nail the sides of the door B so that the nails pass through the straps 18. The accuracy is further inthrough the straps 15 or 18. Directions such as Nail on this line, Nail here, etc., may be employed for indicating the nail lines on the inner liner of the door.
As above stated, I have discovered that imperforate metal straps can be employed and effectively nailed with- I out damaging the door during installation where the straps? are united to the board by strong adhesive, and preferably 7 The board serves as a positive waterproof adhesive. means for supporting the straps against the nail frame A, and when the nails are driven through the door body, the straps do not slide away from the nail but hold their position against the frame A to permit accurate nailing of the straps. elusive, the inner corrugated core 12 additionally serves as an anchoring means for the straps 15 to hold them during the nailing operation. In each of the structures, the core 12 and inner liner 10 serve to hold the nail when it is first partially driven toward the strap 15 or strap 18 so that the nail is then held in position for the final blow which drives the nail through the strap and into the frame A.
In the formation of the door, the inner and outer liners, the core therebetween, and the metal strap-s, together with the imprinting on the inner face of the inner liner 10, may all be simultaneously accomplished in the forming machine itself, the inner and outer liners being adhesively bonded to the core, the metal strap bonded to the board, and the front liner being imprinted to provide the nailing line in alignment with the straps.
In the resultant door structure, the door body is supported by imperforate straps except where the nails actually pass through the straps, and installation is accom plished readily by the indication of the location of the straps from the inner face of the body while at the same time the straps are rigidly secured for nailing to the door body.
While I have shown a corrugated board body and prefer that structure, it will be understood that other door bodies formed of laminated liner sheets, plastic sheets, and other material may be employed in the practice of my invention.
While, in the foregoing specification, I have set forth a specific structure in considerable detail for the purpose of illustrating my invention, it will be understood that In the structure shown in FIGS. 1-4, ini skilled in the art Without de arting from the spirit'of my invention.
