RAILWAY CAR DOORWAY STRUCTURE Filed Feb. 28, 1951 INVENTOR. SIGVALD F. UDSTAD ATTORNEY.
?a.tented Nov. 11, 1952 RAILWAY CAR DOORWAY STRUCTURE Sigvald F. Udstad, Berwick, Pa, assignor to American Car and Foundry Company, New York, N. Y., a corporation of New Jersey Application February 28, 1951, Serial N 0. 213,215
'7 Claims.
This invention relates to railway cars and particularly to an improved structure for use at the doorway of box or similar freight cars and baggage cars.
Shifting of unsecured lading and heavy baggage on the floor adjacent the doorways against the doors when the cars are in transit frequently causes damage not only to the doors, but also to the lading. Various devices are provided for anchoring or bracing the lading at the doorways to prevent its shifting against the car doors, but most of these are either expensive to manufacture and install or have not given satisfactory service.
It is an object of the present invention to provide a simple and efiective structure for preventing shifting of lading against the doors of baggage or box and similar freight cars.
Another object of the invention is the provision of a structure as above described which in one position serves as a threshold plate for the car doorway and in another position as a lading barrier extending vertically across the doorway to prevent shifting of lading against the door.
Still another object of the invention is to provide a two-part threshold plate for railway cars comprising a fixed part and a hinged part swingable to a vertical position extending across the doorway where it constitutes a lading barrier.
A further object of the invention is to provide a structure of the type described adapted to be releasably secured in vertical lading barrier position by retainer means lying flush with the surface of the interior wall lining of the car whereby both the retainer means and lading are protected against damage by the other.
These and other objects of the invention will be apparent to those skilled in the art from a study of the following description taken with the accompanying drawings in which:
Fig. 1 is a transverse sectional view taken through the doorway of the car, the hinged part of the threshold plate being shown in vertical lading barrier position by full lines and in horizontally extending position by broken lines;
Fig. 2 is a side elevational View taken from within the car approximately on line 22 of Fig. 1 and in which the threshold plate is shown by broken lines when in its raised lading barrier position extending across the doorway;
Fig. 3 is a sectional plan view of the structure taken approximately on line 33 of Fig. 2, showing the threshold plate in its horizontal position;
Fig. 4 is a fragmentary perspective view showing one of the retainer members in engagement with the threshold plate for releasably securing the latter in vertical lading barrier position, and
Fig. 5 is a sectional plan view similar to Fig. 3, but showing the hinged threshold plate extending vertically across the full width of the car doorway where it constitutes a lading barrier.
Referring now more in detail to the drawings, the structure at the doorway is shown of a car having an angle side sill 6 and a sill reinforcing member in the form of a bulb angle 8, as is conventionally provided. Spaced channel-shaped door posts it are secured to the side sill 6 defining a doorway, the outer flanges of the posts having depressed lower portions secured to the vertical leg of the side sill in the usual manner, as more clearly shown in Fig. 1. The vertical leg of the side sill is cut down between the posts as indicated at l2 to provide for the doorway, as also more clearly shown in Fig. 1. Floor boards I4 extend transversely of the car and are supported on the horizontal legs of the side sills, a reinforcing and supporting angle l6 being secured to the short leg [2 of the side sill at the door opening, as is customary. It is, of course, to be understood the structure is the same at both sides of the doorway and that the car is usually provided with a doorway in both side walls of identical structure, and therefore only one side of the car and, with the exception of Fig. 5, only one side of the doorway is shown. A door sill plate IB secured to the floor It in the doorway by countersunk bolts 26, which also secure the floor to'the side sill structure, extends outwardly thereover and beyond the support angle l 6 where it is provided at its outer edge with a downwardly turned flange 22. Additional reinforcing means for the support angle and sill plate may be provided if desired by a small angle 24 secured thereto as shown in Fig. 1. The doorway is closed by any suitable door, such as that schematically indicated by broken lines at D in Figs. 1 and 3, which may be supported by any suitable means (not shown). The structure of the car at the doorway so far described is more or less conventional, and applied thereto is the combined threshold plate and lading barrier arrangement now to be described.
The threshold plate generally indicated at 26 includes a fixed part 28 rigidly secured by countersunk bolts 38 to the car floor I4 adjacent the inner side of the doorway. I-Iingedly connected to the fixed part 28 by pin 32 is a swingable portion 3d of the threshold plate, the floor being recessed at 36 along the inner side of the doorway to accommodate the hinge structure joining the two parts 28 and 34, which are formed with tapered outer edge portions 31 for an obvious reason. In the instance shown, an integral type hinge is provided, formed by bending the associated dovetailed edge portions of the plates 28 and 34 around the pin 32, but of course any suitable type of separate hinge element could be used for connecting these plates- The hinged part 34 of the threshold plate is thus adapted to be raised from a position extending horizontally in the doorway between the door posts to a vertical position where it serves to provide a lading barrier extending across the doorway. The hinged threshold plate is releasably secured in the lading barrier position by retainer members 38 pivotally mounted at 40 on the short inner flanges 42 of the channel door posts at opposite sides of the doorway. The door posts ID are provided with wood fillers 44 to which is secured the interior wall structure for the car comprising the lining 46 and inside finishing strips 48. As more clearly shown in Figs. 3 and 5, the lining 46 and inside finishing strips 48 are flush and project inwardly beyond the exposed inner face of the inturned flange 42 of the door posts H]. The lading barrier retainer members 38 pivotally mounted on these exposed interior post flanges 42 are of such dimensions as to lie wholly within the surface plane of the interior wall lining structure where they are prevented from damaging the lading and also are protected from damage by shifting of the lading. The lading barrier retainer members are formed to provide a bifurcated swinging end portion 50 adapted to straddle and engage the tapered edge portion 3'! of the hinged section 34 when in operative position to releasably secure the latter vertical lading barrier position. The pivotally mounted retainer members 38 when in the inoperative or released position extend substantially vertically on the exposed inner face portion 42 of the posts 10, as shown by full lines in Figs. 2 and 3, being releasably held in such inoperative position by keeper means 54 secured to the inner face portion of the post by bolts 56. The keeper means for the retainer members may be of any suitable or desired type, such as that shown, comprising a plunger 58 constantly and resiliently urged to engage in operative position by spring 80 mounted in a housing 62.
From the foregoing description, it will be seen that a simple and effective device has been provided for preventing shifting of unsecured lading and baggage at the doorway against the doors of the cars while in transit. During loading and unloading of the cars, the hinged part 34 of the device extends horizontally over the door sill plate l8 to provide, with the fixed part 28, a threshold plate structure, the retainer members 38 being held in inoperative position from obstructing the open doorway. Upon completion of the loading, the hinged part 34 is easily and quickly raised to vertical lading barrier position across the doorway and the retainer members 38 swung into engaging position releasably securing it there to prevent shifting of lading against the doors during transit of the cars.
The invention may be modified in various respects as will occur to those skilled in the art and the exclusive use of all modifications that come within the scope of the appended claims is contemplated.
