CAR-ROOF.

Application filed March 20, 1911. Serial No. 615,732.

To all whom z't may concern:

Be itknown that I, HERMAN Pairs, a citizen of the United States, and resident of Michigan City, county of Laporte, and State of Indiana, have invrnted certain new and useful Improvements in Car Roofs, of which the following is a Specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to roofs for freightcars, its object being to provide a roof frame of great strength. i The invention consists in the .novel features of construction as hereinafter described, and as illustrated in the accompanying drawings, in which- Figure 1 is a transverse section throughthe frame of the car roof, Fig. 2 is a detail plan of the same; Fig. 3 IS a detail in perspective of one of the I-beams of which the carlines a're forn'ied, partially completed; Fig. i is a similar view showing the completed carline; 5 is a detail in perspective of the (:l'l'lllitfSl'lOWllig the end in incomplete form, and Fig. 6 is a sii'nilar view showing the end of the carline as completed.

'lheside plates of the roof frame are shown at 10, 11'. The car-lines 12, only one ofwhich is shown, are formed of metal I-be..ms preferably extending continuously from side to side of the car. These car-lines have their upper flangesdepressed to form seats for-the purlins l3 and the ridge-pole 14 These depressions are formed by first apcrturing the web 15 of the beam, as,

shown at 16, the upper side of the aperture.

preferably being a little lower than theun- (lei-face of the top flange 17 of the beam. This flange, together with the portion of the web above the aperture, is then forced downwardly into the aperture, 'as shown in Fig. 4, thereby forming a recess 18 for re ceiving the purlin or ridge-pole. This construction provides wide seats for the purlins and ridge-pole without materially weakening the carline. The purlins and ridge-pole may be of wood, as shown. The beam of which the carline is formed is originally of Specification of-Letters Patent.

greater length than required for. the completed structure. A portion of one Wing of its top and bottom flanges of its excessive length is cut away, as shown. at- 19 in Fig. 5. T he end portion ofthe beam is then folded laterally on a. line with the end of the cutaway flange 20, asplainly shown in Fig. 6, thereby providing a. flattened ,end 21 for abutting against the inner face of the

plate

10 or 11, and a top flange 2'2 for resting upon such plate. \Vhen, as shown in Fig. 1, the side plate is of greater depth than'the car-line, the lower flange 23 of the overfolded portion of the beam may also-lee cut away. Bolt-holes are formed inthe -,ov 3rfolded portion 21 of the beam, asshowyn, to permit the carlirie to be secured to-the side plate. By this construction the airline-is provided with an integral flange which rests upon theside plate of the roof frame and relieves the, securing bolts of shearing strains. While the inner flanges of the lateral end extension of the beam are shown as entirely ren'ioved, it is obvious that'as this is done merely for the purpose of facilitating the bending of the beam, the cutting away may be limited to the immediate proximity of the bend. The roof frame thus formed .is-sinn le of construction and of great rigidity and strength.

While the I form of beam is preferred for some reasons, flanged beams of other forms in cross section may be employed in practising the invention. 1

I claim as my invention- 1. In a air roof.fin con'ibination, a metal carline comprising an I-beam having its web apertured and its upper flange de- .pressed into the aperture to form a seat for the purlin.

2. In av car roof, in combination, an integral I-beam carline having a plurality of apertures in its web portion and having its upper flange depressed into such apertures to form purlin seats.
