construction and more particularly to lies thereof and llas special reference levemente in tlie framing of suoli principal. objects of my present invenu re tiie provision of a body construction involving tile use ci' metallic members, wherein a given weight oli metal is most advantageously employed in the production of a body ci maximum rigidity and strength, a minimum of Weight, simplicity of manufacture, avoidance of waste of material, and

' low cost; the provision of an improved arrangement of end post construction; the pro-V vision et an improved carline construction which is' adaptable for employment asaconfl ponent part oi a composite and plate construction; the provision of improved means for securing the posts to the .end plate, and 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 liereinalter appear.

ln attaining the foregoing objects and certain additional advantages to be below disclosed, l have provided the construction illustrated in tbe accompanying drawings,

Referring irst more particularly to l or' the (lr-wings, it will be noted ti A have here shown a car ira-ming and body employing side sills lll-d., center sills li, ll, intermediate sills l2, lil, an end sill, lil, corner posts ll, ll, counter braces l5, l5, side posts i6, i6, side plates 17, l?, and purlins 18, 18, the construction tlius lar described vately by carlines 20,botl1iol specialconstrnction, which l will proceed to discuss more fully 1n connection with ljiigs. E2 and d to 8,

and said end plates being in turn supported y in part by the end posts 2l which l will pro ceed to discuss more fully in connection with, Figs. 2, 3, 9 and 10.

In manufacturing the carlines 20, cnn' bodying my present improvement, l preferably employ a flat rectangular piece, 3G, (Fig. '7) of sheet or plateA metal, or suitable material, and press outwardly oppositely inclined flanged portions Si, by l bending the sheet along the line indicated at 33 until the portions 3l, 32, assume a posi tion at substantially a right angle to e horizontal plane of the strip, tbe opposie` inclined anges 3l, 32, formi the purpose of convenience compression portion ci? the carline or plate, simultaneously pressing outwardly in the opposite direction 1from sucb. plane oppositely inclined tension portions, flanges 34 and 35 (which may be seen en inspection.

of Figs. 2, and 6 to 8), wbicli last named tension portions are formed by bending the sheet along tbe line indicated Aat 3.o, and si multaneously giving the web tiene termed.

` the reversely curved or section clearly te tension surfaces 35 are preferably Aextended outs may be made 'as indicated at 39, 39, for

the formation of brackets 40, 40 (see Figs. 1 and 2), adapted to bear against the inner side of the side plates 17, 17, and of hangers when secured in position, as by bolts 41, 41,

braeingthe end plates or carlines against horizontal or rocking movement relatively to the side plates 17, v17 the formation of said brackets 40-40 leaving outwardly projecting hangers 42-42 by means of which the earline 20 may be suspended from the plates 17, bolts 41 (Fig. 1) being conveniently employed for securing the earline in predetermined position.

As will be apparent on inspection of 2 and 6, the formation of my improved end -plate or earline by the method just described will provide oppositely inclined compression surfaces 31', 32,v gradually 'increasing in width from the center of the end plate 19 toward the ends thereof and thereby giving a maximum width to the projecting hanger portions 42, 42, whereby an additional bracing effect against horizontal strains may be attained, 'the method referred to further providing tensionl surfaces 34 and 35 which taper from the center of the carline toward the yend thereof, thereby affording a maximum amount of material for the formation of the brackets 40, 40;

0n viewing Fig. 2, it will be observed that for the purpose of bringing the ends of the roof sheathing directly down upon the ends of the cai-lines, that is, upon the hangers 42 thereof, and thereby when intermediate purlins 18 are employed, avoiding the necessity of using filler blocks at suchends, I provide the carlines with bends -as indicated at- 44a, 44a, whereby the principal advantages of my present construction areall retained,

` but the roof construction is somewhat simplilied.

On viewing Figs. 4 4and 5 it will be 0bserved that the compression surfaces 31 and in opposite directions relatively to the curved web 37, this affording a rest or support for the filler block 19a of the end plate 19 as, is clearly to ybe seen from inspection of such figures.

Referring now more particularly to Figs. 1 and 3, it will be observed that the end posts 21 are preferably of I-beam construction, the surfaces of the web 44 thereof being disposed in a plane parallel to the longitudinal axis of the car, instead of transverse thereof, as is the common practice, the outer ends of such web being cut away from the flanges and bent ata right angle to the naeaoes geous in the following respects, viz.: by the disposition of the web in the manner indicated a greater resistance to bending strains is attained than when the web is arranged transversely of the axis of the car. -Furthermore nailing blocks 50, 50, may be inset between the opposed flanges 46, 47, (see Fig.

3) and held in position by intermediate braces 51 51, nailed thereto as indicated at 52, 52, (see Fig. 2), such nailing blocks '50, 50, forming bases to which the outer sheathing 53 and inner sheathing 54 may be nailed asshown.

Further referring to Fig. 1 it will be observed that the opposite end plate structure 19 is secured by means of tie members 351435a to the roof earline 20 which is arranged immediately to the-rear of the end of the car. Such arrangement further serving to secure the end plate construction in place and prevent it from dislodgment therefrom in the event of severe shock.

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