Specification of Letters Patent.

Patented Nov. 22, 1910:

v Application filed Iay 12,191l). Serial No. 561,024. 1

To all whom it-may concern:

Beit known that I, Enson C. Cove'in', re-

siding at New Kensington, in the county of- West-moreland and State of Pennsylvania,

have invented a certain new and useful Im-" .proven 1ent 1n Metallic Carlines, of which the following is 'a full, clear, and exact description, reference being had to the accompany ing drawings, which form part of this specification.

This invention relates to metallic carlines for box and similar cars, and has for its primary object to, provide a construction which for the same weight of material will give greater -strength thanis present .inthis member as'heretofore constructed.

It also aims to provide other details of construction, as will be hereinafter more fully described. u y

I will now describe my invention, referring toi theaccompanying drawings, so that.

others skilledin the art to which it appertains' may understand and construct the same.

Figure 1 is a vertical section through a box car showing my improved carline applied thereto; Fig. 2 is a section of the carline taken on the line-22 of Fig. 1; Fig. 3 is a similar view taken on the line 33 of Fig. 1; and Fig. 4 isa side elevation of the end of the carline; showing modified end construction.

In the drawings the reference numeral 2 indicates the siding, 3 the side plates, t a carline, 5 the purlins and 6 the roofing of a box car.

My 'carline comprises the channel member 7 arranged so that the flanges 8 project up ward and is bowed to take the shape ,of the roof. The web portion 9, projecting beyond the flanges 8 at each end of the carline, is turned down, forming the flanges 10 by means of which the cal-line may be bolted or otherwise fastened to the side plates 3 of the car. To strengthen this channel shaped carline against deflection under operative stresses, I form in the web portion 9 thereof,

the substantially U -sh.aped depression orreinforcing flute 11, which projects preferably in a direction opposite'to that of the flanges 8',"-thus forming, in combination with these flanges, a trussed construction which effectually meets the stress conditions of me- A tallic carline's. This depression 11 may feather 01f at each'end as it approaches the respective ends of the carline, as shown in Fig. l, or may extend from end to end of'the body of the carline, as shown in Fig. 4, and

indicated by the numeral 11'; the two arrangements not affecting the strength of the truss but merely presenting differently shapedend ibolting flanges. At suitable intervals alongthe carline, the depression or flute 1-1' is square finished or bossed as indicated bythe; numeral 12, so as to-afiord appropriate seats for the head or nut of the fastening means 13 of the purlins 5. /A wood filler 14-, mounted between the flanges of the carline presents suitable fiat seats for the pui'lins. This wood filler, however, in

the absence of pu'rlins; also serves as a nailing strip for the roof boards or plates of the car. I

I prefer to construct my improved carline from a channel member of conventional cross section. The distribution of material in the ordinary commercial or conventional rolled channel section being such as to provide greaterthickness of metal in the flanged portions than in theweb, with the web portion reinforced as in my improved carline there is presented a light weight construction capable of meeting the maximum roof stresses. I find under test, that my invention increases the strength of the ordinary channel carline 300 per cent.

-The advantages of my invention will be appreciated by those skilled in the art.

It will be apparent that many changes may be made in the construction shown which would not be a departure from my invention, and I do not therefore desire to limit myself theretofi Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A metallic carline embodying a conven- 'tional rolled channel section having formed in the web portion thereof a. longitudinal corrugation.

' 2. A metallic carline embodying a conventional rolled channel section having a substantially U-shaped longitudinal corrugation formed in its web portion,' and projecting in a direction opposite to that of the 105 flanges. In testimony whereof, I have hereunto set my hand.
