Specification of Letters Patent.

Patented sept. 13, 1910.

Application led May 2, 1910. Serial No. 558,986.

To all whom 'fit may camera: y

Be it known that I, PETER -H. MURPHY, a citizen of the United States, and a resident of the city of Pittsburg, in the county of `Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Car-Roofs,of which the following isa specification,

This inventionrelates to car roofs and 'more-particularly* to the carlines for supporting thesame., It has for its principal objects tov secure a' sim le and inexpenslvc construction which is ight and rigid, to overcome the weavin motion of the ,roof structure,'and to attain certain'advantag'es hereinafter more fully appearing.

The invention consists in the arts and in 'the arrangements and combinations of parts hereinafter described and claimed. Y

In theA accompanying drawin s which form part of this specification .andV wherein like symbols refer to like parts wherever they occur;l Figure l is a'transverse section through lone of the side plates of a car showing a pocket casting secured thereto and an I- shaped l.metal carline with a wooden filler piece bolted thereto; Fig. Qis atop plan View; Fig. 3'is a fragmentary top plan view of one end portion ofthe carline; Fig. 4 is a top plan view of a pocket 4casting adapted to receive the counterpart end portions ofthe carline; Fig. 5 'is a section on the line 5-5 of4 Fig. 3; Fim 6 is a section on the line y6 6 'of Fig. 4; lilzig. 7 is a face view of the'pockt casting; and Fig. 8 is a transverse section through uthe I- shaped metal carline with the wooden filler piece thereon.

' As shown in Figs. 1 to4 8,- inclusive, the carline comprises an ordinary commercial I-beam 1 with itsweb portion dis osed horizontally. The opposite end portlons of the I-beam are splitfon opposite sides at the baseofthe flanges and the flange poltions 2 thus severed from the web are bent laterally and the end portions' of the web are turned l downwardly.

Secured to the inner faces of the side plates 4 are pocket members or castings 5 each comprising a plate portion having bosses 6 on its outer face near its ends. The bosses 6 are fitted in seats or mortises provided therefor inthe side plate. On the inner face of each of the castings 5 are a pair of oppositely disposed pockets 7 whose lower portions are counterparts of the latorally-turned flange portions 2 of the I- beam. These castings are securedby bolts 8 ywhich are passed through the side plates and bores in the bosses The downturned web port-ionsl 3 of the with a perforationlO. in the plate ortioni of the -castings. 5, and 'a securing olt 11' is passed through said perforations after the laterally-bent flange-portions 2 are seated in their `respective pockets 7. By` having -carline are perforated, as at 9, in register the pockets 7 y arranged to snugly lit lthe laterally-bent flange portions 2 and securing the web portions 3 and castings 5 to the side plates 4 of the ca 'r b the bolts l1, a rigid connection vis elfecte By reason of the vcastings 5t being secured to the Aside plates 4 at points av considerable distance ,on each side of the longitudinal center of the carline and the bosses 6 being sunk into 4the I side, plates 4', the substructure of the roof is materially stiflened; that is, the effect is substantially `the same as if beams of rel- .atively wide transverse ,sections had been used.

A wooden filler or nailing strip 12 is bolted to the top face of the horizontal web of the I-beam and its lower corners are preferably chamfered to correspond with the contour of the inner faces of the Aflanges of the beam.

Obviously, the device admits of considermy invention. Therefore, I do not wish to be limited to the specific construction andarran'gement shown.

What I claim is:

1. In a car roof, the combination with the side plates, of a carline comprising an I- beam whose web is parallel vwith the pitch of the roof, the ends of the web being slit parallel and close to the flanges and turned downwardly,- and the slit portions of the flanges being turned outwardly parallel with and secured tothe side plates. Y

2. In a car roof, the combination with the 'side plates, of pocket members secured to plates, said the inner 'faces of said side pocket members having a. pair o oppositely isposed pockets on their inner faces, and a strut comprising an I-beam whose web ortion is horizontally disposed and w ose opposite end ortionsv are split and turned laterally and tted in the respective pockets of said pocket members.

3. In a car roof, the combination with,

the side plates, of pocket members comprising plate portions which are bolted at their opposite ends to the inner faces of said side plates and having a pair of oppositely disposed pockets on their inner faces, and an I-beam whoseweb portion is horizontally disposed and whose opposite end portions l are split at the bases of its flanges, and the portions of said flanges which .are severed from the web being turned laterally and fitted inthe pockets on said pocket -mem-A bers.

4. ln a car roof, the combination with the- 'side plates, of pocket members comprising plate portions which are bolted at their opposite ends to the inner' faces of said side plates and having a pair of oppositely disposed pockets on their inner faces, and an I-beam whose web portion is horizontally disposed and whose opposite end, portions are split at the bases of its `flanges, and the severed portions of said flanges being turned laterally and fitted in the pockets of saidpocket members, and the web portion of the opposite ends of the beam being turned downwardly and bolted tol the adjoining side plate.

5. A metal carline comprising an I beam whose web portion is horizontally disposed and -whose opposite end portions are split parallel with the longitudinal axis of said beam at the bases of the flanges thereof, the

severed flange portions being turned-outwardly at right angles and the web por tipn at the ends of the beam being turned downwardly, and castings which are adapted to be secured' toy the side plates of the castin car, comprising plate portions having a pair of oppositely. disposed pockets on their inner faces which are counterparts of the laterally-turned flange portions of the beam, the end portions of said castings being perforated to receive securing bolts, and said downtnrned web portion of the beam having a perforation arranged to register with a perforation in the adjoining casting to receive -a securing b olt.-l

A metal carline comprising an I-beam whose opposite end portions are split parallel with the longitudinal axis thereof at the bases of the flanges, the portions of the flanges which are severed from the web being turned outwardly at-right angles and4 i ned at New Kensington, Pennsy1va nia, his 27th day of April, 1910.
