Oct. 27, 1931. E. R. SWANSON RAILWAY CAR Filed May 27, 1929 Patented Oct. 27, 1931 UNITED STATES PATENT OFFICE EARL R. SWANSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO-CLEVELAND CAR ROOFING COMPANY, OF CHICAGO, ILLINOIS, A. CORPORATION OF DELAWARE RAILWAY GAR Application filed May 27, 1929. Serial No. 366,404.

My invention relates to railway cars and "more particularly toa load lifting device adapted to be associated withthe roof structure. A principal object of the invention for supportingly engaging the undersides of adjacent portions of neighboring roof sheets.

A further feature of the invention resides inconstructing a car roof, of the type involving carlines and roof sheets with a beam 7 member extending longitudinally of car, said carlines Y being 'oifset downwardly adjacent their central portions and being rigidly secured to said beam to support the latter in spaced relation to the roof sheets.

Other and more specific features ofthe invention residing in advantageous forms and sectional view of the car roof embodying the invention.

Figure 2 is a'fragmentary transverse sectional view of the roof construction illustrated in Figure 1. i I V Figure 3 is an enlarged detailed view of the portion of the roof construction adjacent "one'of the carlines' illustrated in Figure 1. V Figure 4 is'a fragmentary enlarged detailed view taken at right angles to Figure 3, the roof sheets and associated seam cap being omitted.

As the construction of the roof on opposite sides of its longitudinal center is identical the transverse sectional view illustrated in Figure 2 depicts only a little more than one-half of the roof structure.

Referring more particularly to the drawings 1 indicates one of the side plate members of the roof structure which is preferably of Z-shape having substantially vertical flanges 2 and 3 connected by a horizontal web portion 4. The end plates 5 of the roof which are, as is well known, rigidly connected to the side plates are also of Z-shape having oppositely projecting vertical flanges 6 and 7 and an intermediate web 8.

Extending continuously from one side of the car to the other are a plurality of carlines 9 which, at their opposite ends, are rigidly connected by brackets 10 to the adjoining side plates 1. Each of the carlines is preferably of inverted channel shape having a web 11 and downwardly projecting substantially vertical sides 12 which terminate in lateral base flanges 13. The roof sheets 14 also extend continuously from one side of the car to the other and respectively span the spaces between the carlines. The lateral edges of each of the roof sheets, with the exception of the outer edge of the end sheets, terminate in upwardly projecting flanges l5 spaced slightly from adjacent sides of the carlines. The outer edges of the end roof sheets are flanged downwardly as at 16 for attachment to the end plates. The eaves edges of the roof sheets are flanged inwardly as at 17 to cooperate with flashing strips 18 secured to side fascias 19 carried by the respective side plates.

The adjoining edges of the roof sheets are connected by seam caps 20 which respectively embrace the carlines. The sides of each of the seam caps are offset to form housings 21 for the upturned flanges of the roof sheets.

i The ends of the seam caps may advantageously be flanged downwardly as at 22 and are secured to the side plate by bolts 23. Intermediate their ends the seam capsare firmly secured to their -associated carlines by any suitable means. (not shown).

The load lifting device 24, illustrated in the present embodiment as an I-beam, extends lther'ebetween and be supportedbythe beam; It is, of course, to;beunderstood, as'clear-ly shown in Figure 2,.that the seam ca-ps'ar'e notfbent downwardly, adjacent their central longitudinally of the car substantially midway between the ends of the carlines in spaced relation to the roof sheets. The ends of the beam member arepreferably rigidly connected to the" top flange 6 of the end plates by brackets 25. To support the beam member.intermediate itsiends each of the 1 channel shape carlinesis oflsetor bent downwardly adjacent their central portions, the

amount of olfset being solely determined by the clearance desired between the beam member and roof sheets. The beam member 1s direct-1y securedto the carlines by rivets '26 i which respectively pass through the lateral flanges 13 ofthe-carlines and the top flange Q7 of t he'beam member.

'Byjsecuring the beam member directlyto I the offset portions .ot the carlines it will be perceived that the beam member is rigidly supported in spaced relation to the roof sheets ,SO that 'sufiici'ent clearance is provided b' tween it. and the sheets" to 7 permit any hoisting device suchas a rope,[o r chain to pass portions in a'manner similar to that of the carlines but extend uninterruptedly from one side of the roof to theothen- V To support the root sheetsadjacent the ,centralportion or ridge of the roof means is. preferably interposed between them and the carlines;- V Inthe. present embodiment of the invention this means comprisesja sub- 1 jaanaai y flalbar or strip of metal 28 which fprojects beyond opposite sides of thecarlines a sufiicient distance to adequately support the roofsheets; Eachof the roof sheet supporting membersxis offset treat 29 toembracingly engage the upperportion of its associated carline immediately above the point of attachment of the beam member,

ibeing rigidly connected to the web of the :car'hne by a rivet 30. Adjacent. their offset portionsthesbrackets may be conveniently intermediate the ridge and respective eaves oftheroof.

g-Fromfthe foregoing it readily be p'r'eciatedfthat in additionto providing the i oot str'ucture with .a rigid fhjoi'sting fdevice simpleland reliable means is..also provided ing roof sheets.

for supporting the sheets of the roof adjacent the ridgethereof.

I claim: I V v 1. In a root for railway cars, the combination with a plurality of carlines, of roof sheets respectively associated with and spanning the spaces between the carlines, a beam membersecuredto said carlines in spaced relation to the roof sheets, and means overlapping the tops of said carlines for supportinglyengaging the undersides of adjacent portions of neighboring roofsheets. 1
