ROOF-CARLINE.

Specification of Letters Patent. Patented Sept. 21, 1909. Application filed July 27, 1909. Serial No. 509,761.

To all whom it may camera:

Be it known that I, ALBERT G. ELVIN, of East Orange, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Roof-Carlines, of which improvement the following is a specification.

The object of my invention is to provide a metallic roof carline which shall embody the features of strength, lightness, and special adaptability for use in the framing of railroad cars.

The improvement fully set forth.

In the accompanying drawings: Figure 1 is an end view of a structural shape, (a T rail) adapted for use in the manufacture of a roof carline embodying my invention; Fig. 2, a side view, in elevation, of a portion of the same; Fig. 3, an end view of a T section shape produced by transversely severing the web of the shape shown in Fig. 1; Fig. 4, an end view of another structural shape (in claimed is hereafter this case an I beam) adapted for use in the manufacture of a roof carline embodyingmy invention; Fig. 5, a side view, in elevation,

of a portion of the same; Fi 6, end views of two T section shapes produced by transversely severing the web of the shape shown in Fig. 45; Fig. 7, a side View, in elevation, of slightly more than one half of the length of a roof carline produced from a T sectlon shape of Figs. 3 and 6, and embodying my invention; Fig. 8, a plan or top viewof the same; Fig. 9, a transverse section, on the line a a of Fig. 7 Fig. 10, an end view, in elevation; and, Fig. 11, a transverse section on the line b b of Fig. 7.

In the manufacture of a roof carline embodying my invention, I take a rolled shape which presents, in transverse section, a web and end lateral enlargements or flanges, .as, for example, a T rail, Figs. 1 and 2, or an I beam. Figs. 4 and 5, and, after having heated the rolled shape to a proper temperature, sever the web transversely at or about the middle of its depth, thereby producing two portions of T section, as shown in Figs. 4 and 6. In the case of a T rail, while both the resulting portions may be correctly said to be of T section, that which contains the head of the rail will, of course, have a narrower and heavier base than the other, while, in the case of an I beam, the portions will both be of strictly T section, and of substantially similar sectional form and area. The T sectionshape thus produced is then passed between suitably grooved rolls, which may be done either in the same or a subsequent heat, as may be found most desirable, and rolled into a roof carline, which, when finished, is of the form shown in Figs. 7 to 11 inclusive.

The body, 1, of the carline, is of channel section, its side flanges being turned upwardly, and is bent downwardly from its middle toward each of its ends, in accordance with the pitch or inclination of .the roof in which it is to be used. An integral central strengthening rib, 1, projects downwardly from the lower side of the body, 1, said rib being of maximum depth at, and for some distance on each sideof, the middle thereof, and thence gradually decreasing in depth toward the ends of the body, near which it terminates. The ends of the body are widened out and turned downwardly into transversely extending end flanges, 1 which are provided for attachment to the ordinary side plates of a carframe. The space between the. side flanges of the body may-be utilized for the reception of a wood filler.

The advantages of my invention in the economical utilization of worn or discarded rolled shapes of the character specified, for

the production of a roof carline which is I and decreasing in depth from the middle P01.

tion of the body toward each of the ends thereof.

As a new article of manufacture, .a

5 metal roof carline having a body of channel section, an integral central strengthening rib" projecting downwardly from the body, and

transversely extending end flanges turned downwardly on the body.
