CARLINE AND PROCESS OF MAKING IT.

Patented J-uly 1917.

T0 all'whom it mag concern: 7

Be it known that I, FRED MATHEWS. a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Carlines and Processes of Making Them, of which the following is a specification.

This invention relates particularly to truss carlines such as are used for freight cars having pitch roofs; and the objectof the invention is to produce a light, strong carline from light commercial rolled shapes, such as I-beams and Z-bars.

The invention consists in a carline formed by splitting the web of a rolled metal shape in from each end nearly to the middle, and bending apart the split portions until the split portions at opposite ends of the original metal shape converge and meet at their extremities, where they are secured together, thereby forming a truss.

The invention further consists in the details of construction of the carlines shown in the accompanying drawings.

Further objects and details of the inven tion appear in connection with the following description of the two carlines shown in the drawings; and what the invention consists in is further defined in the appended claims.

In the drawings, wherein the same reference characters designate the same parts in the several views,

Figure 1 is a top plan view of a carline embodying the invention, showing it secured to the side plates of a car;

Fig. 2 is a side View of the same, the side plates being shown in cross-section;

Fig. 3 is a plan view similar to Fig. 1 showing another carline embodying the invention; and

Fig. 4 is aside view of the carline shown in Fig. 3.

The carline shown in Figs. 1 and 2 consists of top and bottom angle bars, integrally connected at the middle by a strut 12, and riveted together at their ends to form a truss. The bottom bars 13 are horizontal, and the top bars 14 are inclined up to their junction at the middle. The horizontal bars form the lower chord of the truss, and the inclined bars are arranged over the horizontal bars to form the ridge and downwardly sloping ends of the top chord of the truss. The top and bottom bars are angle-shaped, and are arranged with their horizontal flanges in contact at the ends and their vertical flanges up on the top bars and down on the bottom bars, projecting away from each: other. Alt the'middle, short angle bars 15 are riveted to the vertical flanges, one on the top and the'othcr on the bottom. The upper flange of the top angle bar formsa horizontal seat upon which the ridge pole of thecar may be supported and held by avertical bolt. The ends 16 of the horizontal flanges of the bottom bars 13 are bent downinside of the side plates 17; and the ends 18 of the horizontal flanges of the top bars are' bent over the side plates. The ends of the top bars rest on the side plates, and the downwardly bent ends of the flanges are bolted together through the side plates and secure the carlines to the side plates.

The carline shown in Figs. 1 and 2 is formed from an I-beam by slitting both of its ends along the mid-line of the web nearly to the middle of the member. The slit ends are bent apart until the two portions of each end extend in opposite directions, and converge with the two portions of the opposite ends. The flanges of the converging portions are pressed into contact at the ends, and are riveted together. The ends of the webs are cut out, and the ends 16 of the bottom flanges are bent straight at right angles to the webs to form brackets, and the ends 18 of the bottom flanges are bent straight out and down parallel to the ends 16 to form pockets for embracing the side plates.

In the carline 19 shown in Figs. 3 and 4, the top and bottom bars are formed from a Z-bar which is slit and bent at the middle as in the carline described above. The top and bottom flanges 20 of the Z-bar are on the upper and lower edges, and the vertical webs lap and are riveted together at the ends, in the carline shown in Figs. 3 and 4; but they may be so bent as to be next to each other, as in the carline shown in Figs. 1 and 2, and the flanges of the angle bars pressed in contact with each other at the ends and riveted together. The ends 21 of the flanges 20 are bent down to provide sockets for the side plates like those of the carline shown in Figs. 1 and 2.

The invention is not restricted to the shapes and forms of metal-bars shown in the drawings; nor to the precise manner of making the carlines described above.

I claim the following as my invention: 7

1. A carline formed by splitting the Web of a rolled metal member at each end, the splitting extending nearly to the middle of the member, bending apart the split endsto extend in opposite directions, said split ends converging at opposite ends of the carline, and securing said converging ends together near their extremities. I

2. A carline formed by splitting the Web of :1 rolled metal member at each end, the splitting extending nearly to the middle of the member, bending apart the split ends to extend in opposite directions, said split ends convergin at opposite ends of the carline,

and securing said converging ends together near their extremities, the extremities of said split ends being bent transversely t0 the carline for securing it to the side plates. 3. A one-piece truss member for a carline having a middle strut portion the ends of which diverge and form converging end chord members Whichare fastened together at their ends, the top and bottom chord members of said truss having horizontal flanges, the top flange being extended over the side plate and the bottom flange terminating at the inner face of the side plate.

4. A truss member for a carline having a middle strut portion and converging end chord members formed from a single piece of metal by splitting its ends, spreading them apart, and securing the extremities of one pair of spread ends to the other pair of spread ends.

5. A member for a carline having an upright middle strut portion and converging top and bottom end chord members spaced apart at the middle of the carline, said end chord members being integral with said middle strut and lapped and riveted together at their ends to form a truss.

Signed at Chicago, 111., this 10th day of October, 1916.

FRED MATHEWS.
