To all Iwhom t may concern:

Bc it known that I, PAUL M. BEARD, residing at St. Louis, Missouri, andLbe'ingsa citizen of the United States, have 'invented.-.1eertain new and useful Improvements in 4All- Steel Roofs, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference beingr had to the accompanying drawings, which illustrate the preferred `orm of the invention, though it is to be yunc erstood that the invention is not-limited'tothe exact details of construction vshown `and described, as it is obviousthat various modifications thereof will occur to persons-skilled intheart. n

In said drawings: p.

Fig. 3 is a transverse sectional view of a detail, the section being taken'on the line 3-3 of Fig. 1.

Fig. 4 is an enlarged fragmentary detail view representing in full and dotted lines the manner in which the carline hereinafter referred to, is cut out and the purlin or ridge pole interlocked therewith in one con` struction.

Fig. 5 is a fragmentary plan view, showing in enlarged detail, the manner of securing the carline and carline anchor in position.

Fig. 6 is an elevational view of the parts shown in Fig. `5.

Fig. 7 is a sectional view, the section being taken on line 7-7 of Fig. 5.

Fig. 8 is-an enlarged detail hereinafter referred to, and

Fig. 9 represents the relative location of the side-plate and roof sheets, hereinafter referred to, when the parts are assembled.

The invention consists of an all metal roof composed of roof sheets having a continuous upstanding Iiange on three sides, which flanges coperate to hold the roof sheets 1n position and a downturned iiange on the fourth side at the eaves overlapping the slde plate, but -is spaced from such side-plate a short distance to allow a limited movement of the sheets, which are free to move under torsional stresses due to service conditions, as the sheets longitudinally of the car are not riveted together,but are merely held together at the ridge over the purlin, or ridge pole, by means of U-shaped caps, shown 1n Figs. 3 and 8, which caps will be under the transverse cap or binding strip J, which latter is' riveted tothe carline, but, due to the contour of the carline, this transverse cap or binding strip has its longitudinal edges spaced from the carline a sufficient distance to allow the end of the roof sheet fiange to lie therebetween and be held loosely in position. i i

rlhe object of the invention is to provide a Hexible all metal roof formed of parts so shaped andcombined as to provide means -for Ventilating the interior of the car to which the roof is applied without the ad- Another object is to provide a roof comprising carlines, preferably formed pressed metal, extending entirely across the the roof from side-plate to side-plate and secured to such side-plates in such manner that the carlines, the carline-anchors securing the carlines in position, and the sideplates coperate to form conduits leading to the interior of the car for purposes of ventilation.

The carline 10, the sectional contour of which is best indicated in Fig. 7, is formed as an inverted channel comprising a ridge portion 11, vertical fianges 12, horizontal fianges 13 and oblique depressed seat. portions 14, on which seat portions rest the inturned edges 15 of the roof sheets 16, which roof sheets are flanged vertically upwardly, as indicated at 17, and are yieldingly locked 4in position by the binding strips J, before referred to, which are secured by the rivets 18 to the upper face of the carline.

.Due to the contour of the carline and the edge portions of the binding strips J, seats at Figs. 2, 4 and 8, and the ridge pole is likewise cut away, as indicated in Figs. 2 and 4, if desirable, and carlines and ridge pole are ,secured together by means of tie straps 21, riveted to the lower flanges 13 of the carlines and the lower flanges 22 of the ridge pole.

Fig. 8 is a section on line 8- 8 of Fi 7 and 1s si1nilar to Fig. 3, showing, in a dition, the ridgev pole cap 32 having flanges 31 lapping over the 4side flanges 1.1 on the roof sheets and; in turn, being overlapped b v the ebinding strips J.

The ridge pole cap `is reinforced by one or more corrugations 33.

The invention -alsocomprises a new carline-anchor, bestfshown in Figs. 2, 5 and 6, which is especially adapted for connection to a flanged metallic car-side-plate, which car-side-plate in the present construction is formed of a commercially rolled Z-section, though a 'flanged pressed section would answer, if desired.

Referring specifically to the carline-anchor in the figures noted, the bottom portion of such carline-anchor is of relatively box formation, comprising a bottom ledge 40` vertical wall 41, side walls 42, and an outstanding vertical wall 43, which latter is preferably provided with a short inwardly projecting ledge 44, on which rests the carline before referred to.

The carline-anchor preferably rests upon the outstanding flange 46 of the Z-shaped side-plate 47, and is riveted thereto through the ledge 40 by means of the rivet 48 and, if desired, additional rivets, as 49, may eX- tend through the vertical wall 41 yof' the car? line-anchor into the web 50 of the car-sideplate.

Connecting the outstanding wall 43 with the vertical walls 41 of the carline-anchor, are inwardly extending walls 51, which with said wall 43 form a U-shaped pocket adapted to telescope with and be secured to the outstanding or upwardly' projecting portions of the carlines.

To adapt the carlines for the connection above indicated, the horizontal flanges 13 thereof are cut through transversely of such flanges to the vertical web portions 12 in approximate vertical alinement with the outer face of the web 50 of said side-plate, and the partially severed fragments of such flanges at the ends of the carlines are bent vertically downwardly so as to extend parallel, or substantially parallel, with the Walls or flanges 51, before referred to, and the rivets 55, shown in Figs. 2, 5 and 6 secure the vertical flanges 12 and thedownturned portions ofthe flanges 13 to said walls 51, thereby firmly securing the carlines in position after which the roof sheets 16 are placed in position resting upon the outstanding flanges 13 of the carlines and being seated in the pockets 14, between the carline and the binding strips J, as before noted.

Lugs on the inwardly extending walls 51 of the carline anchor are indicated at 56. Their object being to provide a holding surface to preventfthe roof sheets from sliding outwardly. As shown in Fig. 5 these lugs bear against the ends of the side flanges on the roof sheets.

Due to the thickness of the flanges 13, which rest upon the inturned flanges 46a of the car-side plate, it will be noted that the roof sheets 16 are held in position above, but slightly removed from, the flanges 46a of said side-plate, thus providing clearance which will permit torsional movement of the roof sheets without undue friction against the side-plate.

The peculiar constructionpf the carline anchor, in conjunction with the carline of inverted channel shape, provides a ventilated car roof supporting carline, which is closed at its outer end by means of the wall 43 of the carline-anchor, and due to the fact that said wall 43 is positioned outwardly from the vertical wall 41, a clear passage is provided for ventilation above the side-plate through the carline-anchorl and outer end of the carline and into the interior of the car, as indicated by the arrows in` Fig. 2.

The wall 43 closes the outer open end of the carline to prevent ingress of water to the interior of the car and, due to the fact that such wall 43 extends downwardly below the upper face of the side-plate, the interior of the car is protected while leavingample opening through the conduit thus formed for the necessary ventilation.

What I claim is:

1. In a ventilated car roof, a side plate,

a carline anchor secured to the outer side thereof, projecting thereabove and provided With an outstanding wall, and a carline of inverted channel form passing overl said side plate and having an open end por* tion closed by said outstanding Wall and extending below the top of said side plate to be interlockingly retained between the same and said wall, said anchor and carline forming an air duct to a car interior.

2.
