GAR ROOF Application filed June 1,
The invention relates to metallic car roofs of the riveted type and the invention consists in certain novel features of construction as hereinafter set forth.
In the drawings:
Figure 1 is a plan view of the roof;
Figure 2 is a side elevation thereof;
Figure 3 is a cross section on line 3-3 of Figure 1;
Figure 4 is ure 1.
In the present state of the art metallic car roofs may be classified in two types, first, flexible, where the roofing elements are relatively movable and second, rigid or riveted constructions where the adjacent elements are in fixed relation to each other. The present invention relates to the latter type but has for one of its obj ects the utilization of elements which are also applicable to the flexible type. Thus in the flexible type it is usual to employ roofing sheets arranged between the carlines and having upstanding flanges and also caps for embracing the carlines and upstanding flanges of the sheets, but permitting relative movement thereof. With the present invention we utilize the roofing sheets with their upstanding side flanges and the caps for embracing said flanges, but combine the same with a peculiar construction of carline such as to permit of riveting the three members to each other. The construction is also one which while preventing any relative movement of the elements at the point of attachment nevertheless possesses a certain amount of flexibility so that the stresses due to the weaving of the car frame are not concentrated at any one point.
In detail, A are the roofing sheets which are provided at their side edges with marginal portions A in a slightly higher plane and inclining upward towards the outer edges and with upstanding flanges A at said outer edges. B are transverse caps which are provided with downturned side flanges B parallel to the flanges A and outwardly extending flanges B parallel to the portions A. C are carlines, the main body portion of which is of channel cross section with sides which flare outward in an upward direction. At
a section on line 47-4 of Fig- 19a1. Serial No. 541,505.
MIGHI- the upper ends of the sides are outwardly l extending portions C which are return bent at C to be parallel with the portions A and B of the sheets and cap and beyond the portion C are portions C parallel with the portions A and B of the sheets and caps.
Longitudinally of the carline or transversely of the car, the cross section is progressively increased in depth from the sides towards the center.
In assembling the roof the flanges A B and G are placed together and secured by rivets D spaced at suitable intervals. These rivets together with the anchor flanges A B, C will hold the elements in fixed relaamount of flexure is possible due to the oppositely extending return bend of the carline which will relieve the structure from over-stressing at any one point during the weaving of the car frame. Another advantage of the construction is that the plane of the sheets is intermediate the upper and lower ends of the carline which forms a stronger structure.
tion to each other. However, a certain The roof is attached to a car frame having Z-bar side plates E. The carlines are provided with downturned flanges F riveted to the upturned flange E of the bars E and the sheets and caps are also providedwith downturned flanges G and H which are similarly riveted.
What we claim as our invention is:
1. A car roof comprising roofing sheets having upturned side flanges, carlines of channel cross section having at their upper ends return bent portions terminating in outwardly extending flanges and caps embracing the channel and return bent portions of said carline and having outwardly extending flanges parallel to the flange of said carline, said sheets, car'line and cap being riveted to each other.
2. A car roof comprising carlines of channel cross section having upwardly andoutwardly flaring side walls, return bent portions at the upper ends of said side walls and laterally outwardly extending flanges, roofing sheets and carline caps having portions parallel to the return bent and laterally extending flanges of said carlines and nested therewith, the said parts being secured to each other by riveting.
3. In a car roof, a carline formed of channel cross section with return bent portions at the upper ends of said section and outwardly extending flanges, a cap fitting over the channel of said carline and extending parallel to said return bent flange and laterally extending flange, and a roofing sheet having a marginal portion parallel with and extending between said cap and carline and secured thereto by riveting.
In testimony whereof we aflix our signatures.
