To all whomit may concern:

Be it known that I, THoMAs NATHAN'RUS SELL, a citizen of the United States, and a resident of Chicago, in the State of Illinois,

a have invented certain new and useful Improvements in v()arlines, of which the follow infi/iis a specification.

y present invention relates general to car construction and more particularly 1 to the bodies thereof and has special reference to improvements in the carlines used in framing car roofs, and'most specifically to end carlines or end plates.

The principal ob ects of my present invention are the provision in a body con struction involving the use of metallic members, of a carline wherein a given weight of metal is most advantageously employed in the production of a body of maximum. rigidity and strength, a minimum of weight, simplicity of manufacture, avoidance of waste of material, andlow cost; the pro" vision of an improved arrangement of corn hined end carline and filler block forming an end plate construction; the provision of an improved carline construction which is adaptable for employment as, a component part of a composite end plate construction; the provision of improved means for securing the end plate in turn to the other members of the car framing in order to secure the greatest strength and rigidity of the frame, and roof construction and attain the greatest resistance to all bending moments and other stresses, together with such other objects as may hereinafter appear.

In attaining the foregoing objects and certain additional advantages to be'below disclosed, I have provided the construction illustrated in the accompanying drawings,

wherein:

Figure 1 is a perspective view of the carline before the filler block is placed in position to form the composite end plate structure;

Figure 2 is a plan view of the composite end plate structure;

Figure 3 is a view of the blank from which the carline is manufactured;

Figuresd and 5 are transverse sectional views of the composite end plate structure taken on the lines fl-.4:'and 5--5 of Figure 2, each showing, however, a fragment of a roof purlin in position and supported by a flange of the end carline;

Figure 6 is a fragmentary view, partly in vertical section, of, a corner of a car body structure, illustrative of the method of attaching the composite end plate structure to such body;

Figure 7 is a sectional. view taken on the line 7-7 of Figure 6.

Referring first more particularly to Figures-1, 2 and 3 of the drawing, it will be observed that in manufacturing the carlines 20, embodying my present improve ments, I preferably employ a fiat rectangular piece, 30, (Figure 3) of sheet or plate metal, or similar suitable material, and press outwardly oppositely inclined flanged portions 31, 32, by bending the sheet along the longitudinal line indicated at 33 until the portions 31, 32,

named tension portions are formed by bending, the sheet along the line indicated at 36, and simultaneously giving the web 37 thus formed the markedly curved S section clearly to'be seen on viewing Figures at and 5, there being no sharp bonds at the points a and b. The carline 20 of said Figure l and the composite end plate 19 are of substantially the same construction, save that in the composite end plate the end carline support a filler-block indicated at 19".

By the employment of suitable dies, cutoutsmay be made as indicated at 39, 39, for the formation of brackets 40, 40 (see Fig" ures 1 and 3), adapted to bear against the side plates of the body framing, one indi cated at 17, Figure 6), when secured in position, as by bolts 41, bracing the composite end plate or end carline against horizontal or rocking movementrelatively to the'side plates 17, the formation of said brackets 40-.40 leaving outwardly projecting hangers 42-42 by means of which the carline may also be suspended from the plates 17,

bolts 43 (Figure 7) being conveniently employed for securing the carline in predetermined osition. 1

As will be'apparent on inspection of Figure 1, the formation of my improved composite end plate or carline by the method just described will provide oppositely inclined compression surfaces 31, 32, gradually increasing in width from the center of the carline 20, toward the ends thereof and thereby giving a. maximum width to the projecting hanger portions 42, 42,-whereby an additional bracing effect againstliorizontal strains may be attained, the method referred to further providing tension surfaces 34 and 35, thereby affording a maximum amount of, material for the formation of the brackets On viewing Figures 1, 6 and 7, it will be observed that for the purpose of bringing the ends of the roof sheathing directly down upon the ends of the carlines, that is, upon the hangers 42 thereof, and thereby when intermediate purlins 18 are employed, avoiding the necessity of using filler blocks at such ends, I provide the carlines with bends as in dicated at 441 44*, whereby the principal advantages of my present construction are all retained, but the roof construction is somewhat simplified.

On viewing Figures 4 and 5 it will be observed that the compression surfaces 32 and tension surfaces 35 are preferably extended in opposite directions relatively to the curved web 37, this affording a rest or support for the filler block 19 of the end plate 19 as is clearly to be seen from inspection of such figures.

Referring now more particularly to Figures 6 and 7, it will be observed that the end posts 21 as here shown are of I-beam construction, the outer ends of the web 44 being cut away from the flanges and bent at a right angle to the body of such web as indicated at 45, whereby they may be attached to the composite end plate structure 19.

' The improved structure of carline de scribed in the foregoing specification has certain marked features of advantage among which may be noted the,rearwardly extending flanged surface 3132 which supports the purlins 18 and is in turn supported and braced by and against the side plate 17 by the hangers 42 and brackets 40; the forwardly extending flanged surface 34-35 which supports the filler block 19 to which may be nailed the sheathing 53; the curved web 37 which is arranged at an angle to the perpendicular and is therefore more rigid and offers greater resistance to twisting strains than would be the case were the web position and tying to other portions of the body or roof structure, such features of construction, however, being claimed in mycopending application, Serial No. 814,519, filed January 26, 1914, of which this application is a division.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is the following:

1.. A carline having a compression surface and a tension surface of difi'erin contours, the latter having an outer edge ying in a single vertical plane and an obliquely arranged curved web therebetween the upper edge of which lies in a vertical plane parallel to said first-mentioned plane, said compression surface and said tension surface being disposed laterally in opposite directions from said web, and the sum of the width of the parts being substantially the same incross section throughout the carline.

2. A carline having a compression surface, a tension surface, a web therebetween, said web being obliquely'arranged, whereby the compression surface and tension surface lie in ,part one above the other, and a filler block supported by a projecting edge of one of said surfaces.

3. A carline having a compression surface, a tension surface, a curved web therebetween, said' web being obliquely arranged, whereby the compression surface and tension surface lie in part one above the other, and a filler block supported by a projecting {edge of one of said surfaces.

sion surface and an inclined web therebetween formed with connecting portions of large radius of curvature, said compression and tension surfaces being disposed laterally in opposite directions from said web and arranged to lie in part one above the other.

6. A carline having a compression surface, a tension surface, an obliquely arranged web therebetween, said compression surface and said tension surface bemg disposed laterally in opposite directions from said web and arranged to lie in part one above the other.

7. A. carline having a compression surface, a tension surface, a web therebetween, the two longitudinal halves of the web lying in planes intersecting in plan view at an angle adjacent the center of the carline.

8. A carline having a compression surface, having one edge lying in a singlevertical plane, a tension surface having one edge extending beyond said first mentioned edge and lying in a single vertical plane parallel to said first mentioned plane, said tension surface being arranged to lie in part below said compression surface, said tension surface increasing in width progressively towards the center of the carline, and an inclined web connecting said compression and tension surfaces.

9. An S-shaped carline having a curved web portion and a lower flange projecting beyond the curved part of the Web connecting the upper and lower edges of the carine.

10. A pressed-steel carline having a substantially Z-shaped cross-section and comprising a web extending longitudinally thereof, and an upper flange and a lower flange projecting horizontally from said web in opposite directions, said upper flange increasing in width from the middle of the carline toward the ends thereof, said lower flange decreasing in width from the middle of the carline towards the ends thereof. 1

In testimony whereof I have hereunto signed my name in the presence of the two subscribing witnesses.
