12. Claims.

In order to facilitate the interchange of traffic, it is customary to haul freight cars of one railroad company over the tracks of other companies whose bridges and tunnels provide sufiicient clearance for such cars, and the American Asso-v ciation of Railways and its predecessors have established definite outlines that define the maximum vertical and transverse dimensions of freight cars that may be interchanged.

One of the objects of the present invention is to increase the height of the roof as closely as practicable to the established clearance line throughout the width of the car. Another object is to shorten the span of the roof sheets between its supports. Another object is to improve the design of metal side plate to obtain divers advantages hereinafter mentioned. The invention consists principally in the new design of side.

plate hereinafter described and claimed. It also consists in designing and locating the side plates so that they will incline upwardly and inwardly conformably to the clearance outline with their inner margins considerably inward of the side walls of the car and adapted to constitute seats for the roof cover. It also consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings wherein like reference numerals refer to like parts wherever they occur,

Fig. 1 is a plan view of the construction embodying my invention,

Fig. 2 is an enlarged vertical cross section thereof on the line 2-4 of Fig. 1,

Fig. 3 is a still more enlarged section of the eaves portion of the construction on the line 33 of Fig. 1

Figs. 4, 5, and 6 are views similar to Figs. 1, 2, and 3, respectively, showing a'modification of the invention, Fig. 5 being taken on the line 5-5 and Fig. 6 on the line B6 of Fig. 4, and

Fig. 7 is a longitudinal vertical section on the line 1-1 of Fig. 4.

Except for the design of the side plates, the sides of the present car are of well known construction; that is, the sides comprise framing members including posts I organized into atruss or side frame with sheathing 2 on the outer side of said side frame and a lining 3 inside thereof. The side frame has a top member 4, commonly called the side plate, upon which the roof proper 5 is supported.

According to the present invention, the side plate 4 shown in Figs. 1, 2, and 3 of the accompanying drawings is made of one or more lengths of rolled sections. Each side plate has a vertical flange 6 along one side margin which flange laps downwardly 'below and is riveted or otherwise suitably secured to the vertical or inclined struc tural members of the side frame. The body portion I of the side plate, being the portion next to said vertical flange 6 inclines upwardly and inwardly over and beyond the side frame of which it forms part. This body portion of the side plate inclines at approximately the same angle as the established clearance outline. The portion 8 of the side plate next inwardly from the main inclined portion 1 thereof extendsinwardly, preferably with a low upward inclination. At the inner margin of this last mentioned portion 8 of the side plate, there is an upstanding flange 9 to which the roof proper 5 is secured preferably by welds or by rivets 10 that extend horizontally through said flange and downturned flanges ll of the roof proper. Preferably the side plate is secured tothe inner portion of the side wall as well as to the outer face thereof. For this purpose, an anchor plate I2 is welded to'the inner surface of the main inclined portion 1 of the side plate above each side post and is connected by a plate l2a. to the top portion of such post.

In the type of roof illustrated in Figs. 1, 2, and 3, the roof sheets l3 extend from side plate to side plate and have end flanges II that are turned down beyond the upstanding flanges 9 of said side plates and are secured thereto by the rivets l0. In this type of construction, the side margins of adjacent sheets have upstanding flanges I5 which are straddled by inverted U- shaped seam caps Hi, all secured together by rivets 11 extending horizontally through the seam covers and sheet flanges, the ends H! of the seam caps being bent down over the upstanding flanges of the side plates and secured thereto by welds or rivets l9. A running board 20 is mounted along the ridge, as by securing it to angular brackets 2| which are secured to the seam constructions by rivets 22 extending horizontally therethrough. In this type of roof, the

inclined body portions of the side plates'and the eaves portions of the roof seam covers lie close to the established clearance outline A where the running board is close below the same.

The type of roof illustrated in Figs. 4 to 7 is of the neutral axis type wherein the sheets are shaped and secured together to form alternating ribs and channels. In the roof shown, the sheets I30. extend from side plate to side plate, and they have ribs 23 extending lengthwise thereof at a higher elevation than the side marginal parts,

and the side margins have upstanding flanges 24 that are secured together, preferably by welds 25. As shown in Fig. 5, the ridge portion 26 of the marginal panels of the sheet is substantially flat and horizontal; and from this flat ridge portion, the sheets incline downwardly at a small angle and have their ends resting fiatwise on the inner margins of the side plates to which they are secured preferably by longitudinal welds 27 along the edges thereof. In this design of roof, the side plate is of substantially uniform thickness throughout its width and is made of one or more lengths of thick metal plate bent into shape; and the upwardly and inwardly inclined body portion la of said side plate follows the clearance outline A closely almost to the height of the roof proper, and the inner marginal portion 8a of the side plate adjoining the main inclined portion extends inwardly and at substantially the same inclination as the end portions of the roof sheets so as to form a continuous seat for the roof sheets.

In this type of roof, the running board is secured to brackets 2la provided therefor in some of the roof seams. The upper surface of the running board must fall within the established clearance line. The position of the side plate seats for the roof sheets is determined by the position and pitch of the lower panels of the roof sheets, whose ends lie close to but within the established clearance outline A. Thus the side plates are considerably wider' than the side plates heretofore used and provide seats for the roof sheets at a higher level and much further inwardly from the side walls than side plates used heretofore.

The construction hereinbefore described has divers advantages. The side plate is light and easy to manufacture and to assemble in the car structure. By reason of the inclination of the. body portion of the side plate, the side frames of the car can be built somewhat higher than has heretofore been practicable; and on account of such inclination following the established clearance line, coupled with the increase in the width of. the side plate, the side plate seats for the roof proper are located higher than has heretofore been practicable where the roof sheets extend from side plate to side plate. Thus the distance between roof sheets is shortened, the stresses on the roof proper are decreased, lighter roof sheets may be used and the depth or thickness of the roof may be decreased accordingly. Besides, the entire side plate functions as a structural element of the side frame of the car and, at the same time, a considerable portion of said side plate functions to exclude the weather and thus reduces the space to be covered by the roof sheets proper.

What I claim is:

1.
