CARLINE.

meager.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed August 12, 1919. Serial No. 317,004.

To all whom it may/"concern:

Be it known that I, WILLIAM N. OEHM, a citizen of the'United States, and resident of Michigan City, county of Laporte, and State of Indiana, have invented certain new and useful Improvements in Cal-lines, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to carlines, and has for its object the provision of a carline which will be stronger for a given amount of metal than carlines now in use. A further object is the production of a carline which shall give the greatest possible strength while using as little head room in the car as possible.

In the accompanying drawings,

Figure 1 is a detail transverse sectional view of the upper portion of a car body, some portions being omitted;

Fig. 2 is a detail side view of the same;

Figs. 3 and 4 are detail sections on lines 3.3 and 44, respectively, of Fig. 1.

In the drawings 10 designates the carline as a whole. In the construction shown in Fig. 1, the carline is 'made up of flanges 11 and a central channel 12 which is deepest at the central portion 13, and, gradually becoming less, dies out near the plate of the car at 14. Flanges 11 merge into the flat plate end portions 15, which are shown as turned downwardly to lap over the car plates 16, where they may be attached as by means of rivets 17. The horizontal part of the end portions 15 being, as shown, longer than the.

width of the car plate 16 at each side of the car, the channel 12 will be located entirely between the car plates 16.

A reference to Fi s. 3 and 4 will disclose that the metal of which the carline is formed has its greatest thickness at the central portion as to both channel and flanges, and becomes thinner .toward the end portions. The channel of the carline is shown as dying out very closely adjacent to t e side plates, so that the stiffening effect 0 thechannel will be carried well out toward its ends.

The ridge pole of the car is illustrated in Fig. 1, at 26, and may be attached to the carline in a suitable manner, as by a bolt 27. The flanges 11 arm the upper'surface of the carline and serve as the portion of the carline coming in contact with the superposed roof structure;

It is believed that the mode of application of the carline will be apparent "from the above disclosure. lVhile a preferred form of construction is disclosed, various changes of detail may be made without departing from the scope of the invention.

I claim as my invention:

1. A carline for railway cars comprising a member channel-shaped in cross-section and having flanges adapted to contact with the car roof, the channel lying directly below the flanges and being deepest at the center of the carline and dying out near the end portions thereof, the flanges merging into said end portions.

2. A carline for railway cars comprising a member channel-shaped in cross-section, and

having flanges projecting horizontally from the upper edges of the sides of the channel adapted to contact with the car roof, the channel being deepest at the center of the carline and dying out near the end portions thereof, the flanges merging into said end portions, the metal of the carline being thickest at it longitudinal center and diminishing in thickness toward itsends.

3. A carline for railway cars comprising a member channel-shaped in cross-section having flanges projecting horizontally from the upper edges of the sides of the channel adapted to contact with the car roof and lying in the plane of the lower side of the roof, the channel being deepest at the center of the carline and dying out near the end portions thereof, the flanges merging into said end portions.

4. A car line for railway cars comprising a member channel-shaped in cross-section and having flanges projecting horizontally from the upper edges of the sides of the channel adapted to contact with the car roof, the channel being deepest at the center of the carline and dying out near the end portions thereof, the flanges merging into said end portions providing flat plate end portions of greater length than the width of the car platewhereby the channel will fall entirely etween the car plates.
