Application filed August 15, 1919.- Serial No. 317,679.
To all whom it may concern Be it known that l, FREDERICK M. WHYTE, a citizen of the United States, residing at Tarrytown, in the county of lVestchester and State of New York, have invented a certain new and useful Improvement in Metal Roofs for Cars, of which improvement the following is a specification.
This invention relates to car roots, and more particularly to metal roots as applied to freight cars or box cars, the object being to provide an improved root of the type having metal roofing sheets extending between the carlines, and in which each roofing sheet is rigidly secured along one of its side edges while the opposite side edge at the adjacent carline is free to slide to compensate for the twisting and weaving motion of the car without subjecting the roofing sheets to corresponding buckling stressesi Another object is to provide improved means ilor covering and weather-proofing the space between the side edges of the adjoining roofing sheets at each carline.
Another object is to provide an improved construction whereby any one of the metal roofing sheets may be detached and removed for repairs or renewal without disturbing the adjoining roofing sheets.
Another object is to provide an improved end sheet construction whereby the two opposite end sheets of the car roof are made alike and interchangeable.
With these and other objects in view,-my invention comprises certain'improved features of construction which will now be more fully described and claimed.
In the accompanying drawings: Figure 1 is a transverse section taken on the line 1-1 of Fig. 2, extending slightly more than half the width of the car, and showing a metal roof embodying my improvement;
Fig. *2, a side elevation of the same with portions broken away; Fig. 3, a longitudinal section of the same, taken substantially on line 33 of Fig. 1, and showing the carlines at the opposite ends oi: the car and one of the intermediate carlines; Fig. 4, a transverse section of one of the carlines upon a larger scale, and showinn the covering strip and the adjoining edges of the roofing sheets; and Fig. 5, a similar sectional View, but showing a modification in which the binding strip is eliminated, and the roofing sheets are supported directly upon the purlins.
According to the construction shown, the car-lines, 4, are supported at their ends on the side plates, 1, of the car body, in any suitable manner, as, for instance, by means of brackets, 3. While the side plates are indicated as being formed of metal, it will be understood that they may be of wood or other material; also that the carlines may be either of wood or metal, and of any desired shape, although I prefer to form the same of a 2 bar metal section, as shown. The purlins, 5, which are preferably formed of wooden beams, may be bolted to the under side of the carlines, and extend longitudinally oi the car in the usual manner. The sheathing boards, 8, when used, are supported upon the purlins in the ordinary way. The metal roofing sheets, 9, in the type of roof known as an outside metal roof, are laid upon the sheathing boards between the carlines and preferably extend the full width of the car from eaves to eaves.
According to my improvement, each of the intermediate roofing sheets, 9. is rigidly fastened along one of its side edges to one of the carlines, while the opposite side edge is left free to slide relative to the car frame in the plane of the root, and thereby relieve the same from any buckling stresses due to the weaving and swaying, motions of the car while running. As shown, the roofing sheet is provided with an upstanding rebent flange 18 secured to the carline by bolts, 13, and for the purpose of distributing the clamping effect over a greater length of the roofing sheets, the binding strips, 11, of wood or metal. may be mounted on the bolts, 13, for clampinp the roofing sheet against the carline. The binding strips are particularly desirable where thin gage metal roofing sheets are employed, as in an outside metal roof. The opposite side edge of the metal roofing sheet is preferably formed with an upstanding, rebent flange 19 with a free space between the vertical portions thereof, for the purpose of preventing the entrance of water or moisture. T his edge of the roofing sheet is, however, left free to slide upon the sheathing boards. In order tohold this edge of the roofing sheet down flat upon the roof, I preferably pro vide a bearing strip, 12, of wood or other suitable material, the same being supported lengthwise of the carline by bolts, 14, and brackets, 15, mounted on the bolts, 13.
For covering the earlines and weatherproofing the joint between adjacent roofing sheets, I provide the covering strips or. carline caps, 10, having bent down side portions inclosing the strips, 11 and 12, passing beneath the same in contact with the roofing sheets, and having upstanding flanges at the side edges. One of these flanges 20 is clamped to the carline with the flange 18 of the roofing sheet, 9, by
means of the strip, 11, and bolts, 13, while the vertical flange 21 at the opposite side of the carline cap interlocks with the turned over side edge of the adjoining roofing sheet, thus forming a weather-proof joint. The carline caps may extend the full width of the car, but are preferably formed in sections extending a little more than one-half the width of the car and overlappingeach other at the ridge. The carline cap is placed in positionby engaging the upper end thereof with the lower ends. of the flanges 18 and 19 of the roofing sheets at the caves, and sliding the same upward along the carline. The eaves molding, 17, and flashing, 16, are secured on the s1de plate, 1, in the usual way, and the lower edges of the roofing sheets are bent down over the molding. The lower ends of the carline caps are also bent down over the molding and fastened to the side plates.
The end roofing sheet at the rightend ofthe car has an upstanding flange 18 at its left hand side which is rigidly clamped to the carline by bolts, 13. while the right hand edge 22 is turned down over the end plate, 6, of the car, and loosely fastened thereto by nails. The end roofing sheet at the left end of the car is also provided with a flange 18 along its righthand side which is rigidly clamped to the carline by means of strip, 12, and bolts, 14, while its other side edge 22 is bent down over the end plate, 6, of the car, and nailed thereto, The bearing strip. 12, at this left hand carline may be formed slightly different from the other strips for clamping this roofing sheet. The two end roofing sheets are, therefore, made alike, and are interchangeable. I
The running board. 2, may be supported on suitable brackets, 7, fastened to the carlines and carline caps.
When my improvement is employed in connection with an all metal roof in which heavy gage sheet metal is used for the root ing sheets, these may then be placed directly upon the purlins, 5, as shown in Fig. 5. and the sheathing boards, 8, need not be used. In this case also the binding strip, 11, may
be eliminated, and the flanges of the roofing sheet and the carline cap may be fastened directly to the carline by the bolts, 13.
In assembling the parts of the metal roof in position, the roofing sheets are first placed between the carlines, then the bolts, 13, are inserted through binding strips, 11, carline, 4:, and bracket, 15, and the nuts applied loosely to said bolts; bearing strip, 12, is then fastened to the brackets, 15, by bolts. 14, and the covering strip, 10, is then slid into position, as before described. The nuts on bolts, 13, which are accessible from beneath the carline caps, are then tightened and the roof is then complete. The running board bracket, 7, may thus be bolted or riveted to the carlines.
If it be desired to remove any one of the roofing sheets without disturbing the others, the running board brackets or saddles, 7, are first removed from the adjoining carlines, the nuts of bolts, 13, are then loosened from the under side of the roof, whereupon the two carline caps may be removed; the binding strips may then be detached, and the roofing sheet lifted from its position. It may then be replaced by a reversed order of operation, without disturbing the adjoining roofing sheets.
Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a car roof, the combination of the carlines, metal roofing sheets located between said carlines and each-having one of its side edges rigidly fastened to a carline and the other side edge free to slide. and carline caps covering the side edges of ad joining roofing sheets.
