Specification of Letters Patent.
Patented Aug. 3, 1920.
Application filed August 11, 1916. Serial No. 114,396.
To all whom it may concern:
Be it known that I, CLINTON C. MURPHY, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Railway-Car-Door Constructions, of which the following is a specification.
My invention relates to a railway box car door of the outside sliding type, and the object of the invention is to provide a door of this type composed essentially of metal (although preferably lined with wood) which will be so constructed and reinforced as to have the strength, rigidity and durability required for such structures- The invention consists in the novel and improved constructions, arrangements and devices to be hereinafter described and claimed for carrying out the above stated object and such other incidental objects as will appear from the following description.
The invention is illustrated, in a preferred embodiment, in the accompanying drawings wherein Figure 1 is a view, in perspective, of the side of a steel box car provided with the door construction of my invention.
Fig. 2 is a detail view, in perspective, of a guiding and weatherproofing strip with which the upper edge of the door is provided.
Fig. 3 is a vertical sectional view on line 33 of Fig. 1, and
Fig. 4 is a sectional plan on line 44 of fiike characters of reference designate like parts in the several figures of the draw- 1n eferring to the drawings, 10 designates the steel under frame of the car, 11 the sheet metal side sheathing thereof, and 12 the roof, which is shown in a diagrammatic manner. The side wall of the car is shown as formed with a door opening 13. 14,14 are angular metal door posts within which are arranged wood nailing strips 15 to which the wooden side lining boards 16 are secured. flange of which overlaps the floorin 18 at the door opening, the other flange 0 which overlaps and is secured to the under frame member 10.
It will.be realized that my invention is not limited to these details of construction 17 is an angular sill plate, one.
of the car which are shown simply for the purpose of illustrating the application of the door construction constituting my invention to a steel box car of familiar type.
The door comprises a sheet metal panel, consistlng preferably of two sheet steel plates 15) formed with vertical stiffening corrugat ons 20 and with outturned flanges 21 at their meeting edges which are riveted together. The metal portion of the door also comprises, preferably, four metal strips, angular in cross section, which are arranged along the edges of the door as follows: at the upper edge of the door is a 2- bar 22 having a vertical flange 23 overlapping the corrugated sheets 19, an inturned hor zontal flange 24:, and an upwardly proectlng vertical flange 25 which is bent over outwardly to provide a lip 26. To the lower edge of the door is secured a Z-bar 27. On the forward edge of the door is another 2- bar 28 and on the rear edge a channel bar 29 arranged so that its flanges project forwardly. The metal structure thus formed is preferably reinforced by corner gusset plates 30 and is lined with a suitable insulating lining. The lining consists, preferably, though other material might be used, of horizontally arranged matched boards 31 which are secured to the metal structure of the door by bolts 32 or other suitable fastening devices. The boards add considerably to the strength and rigidity of the door particularly when, as in the preferred arrangement shown, they run transversely of the corru ations. The lining boards are preferably tted close up against the Z-bar 28 and channel bar 29.
An insulated metal door, as above described, is very strong and durable but relatively heavy in comparison with the side doors ordinarily used on box cars. I, therefore, providemeans for supporting the door directly on the under frame of the car. The under frame carries the entire weight of the door, a guide being provided above the door opening, the purpose of which is simply to hold the door in vertical position and to guide its movements in opening and closing.
For supporting the door on the under frame I preferably provide a plurality of brackets 33 riveted or otherwise suitably secured to the under frame 10 of the car, and furnished preferably with rollers 34 engaged by the horizontal flange 35 and depending vertical flange 36 of the Z-bar 27. Above the door opening a guiding and weatherproofing strip 37 is provided having a flange 38 for riveting to the side sheathing of the car, and a horizontally disposed channeled portion 39 which extends around the lip 26 formed on the Z-bar 22 with which the upper edge of the door is provided. This arrangement provides a perfectly effective waterproofinIg means for the upper edge of the door. t involves no castings or projecting parts likely to be knocked off if the car is side swiped. lVhile the guiding strip must, of course, be of a length approximately double the width of the door, as it does not carry the weight of the door but simply guides the upper edge of the same, it may be made of relatively light stock. The guiding and retaining means provided by strip 37 and brackets 33 take the thrust of the cargo on the door, in case through careless loading such thrust occurs, the stresses being transmitted by the vertical corrugations which act as beams.
40 is a stop strip secured to the side sheathing of the car at the forward edge of the door opening having an off-set flange 41 adapted to overlap the outwardly projecting flange 42 of Z-bar 28. 43 is a similar strip secured to the side of the car at the rear edge of the door opening (the terms forward and rear having reference to the direction in which the door is moved to open and close it) and providing an offset flange 44 for overlapping the inner forwardly projecting flange 45 of channel bar 29.
It will be seen that the door above described, although quite heavy and massive in its construction, so that it will withstand the hard usage to which all the parts of a railway freight car are subjected, is so supported that it puts no undue strain on the superstructure of the car. Inasmuch as it is carried directly on the under frame any disadvantage due to the fact that it is somewhat heavier than ordinary doors is more than counterbalanced by its strength, rigidity and durability. v
I claim:
1. A railway box car comprising, in combination, Z -bar members at the upper, lower and forward. edges of the door, the first named member having an additional outwardly extending web along its upper edge, and a channel member at the rear edge of the door, corner devices for fastening said members together to constitute a rigid frame, and a sheet metal panel composed of a single thickness of metal secured to said framework and formed with substantially parallel corrugations which terminate within the edges of the panel so as to rigidify the same.
2. A railway box car comprising, in combination, Z-bar members at the upper, lower and forward edges of the door, the first named member having an additional outwardly extending web along its upper edge, and a channel member at the rear edge of the door, corner devices for fastening said members together to constitute a rigid frame, a sheet metal panel composed of a single thickness of metal secured to said framework and formed with substantially parallel corrugations which terminate within the edges of the panel so as to rigidify the same, and wooden lining boards on the inside of the sheet metal panel which extend transversely of said corrugations.
3. A railway box car door comprising, in combination, metal frame members, angular in cross section, at the upper, lower and vertical edges of the door; corner devices for fastening said members together to constitute a rigid frame; and a sheet metal panel composed of a single thickness of metal secured to said framework and formed with substantially parallel corrugations which terminate within the edges of the panel so as to rigidify the same.
4. In a railway car door construction, the combination with guiding and retaining means for the upper and lower edges of the door; of a door which slides back and forth in said guiding and retaining means consisting of a rectangular metal framework, and a sheet metal panel secured thereto formed with a plurality of vertically extending corrugations which terminate within the edges of the panel forming effectively beams which transmit stresses exerted against the door to the upper and lower reinforced edges thereof and to said guiding and retaining means.
CLINTON C. MURPHY.
