This invention relates to car roofs of the all-steel, riveted-up typewherein the roong sheets extend from side plate to side plate and are rigidly secured thereto-and to each other tozform a rigid loadsustaining structure. The principalv object of the present invention is to provide astrong and durable Y waterproof roof of simple construction which can be cheaply manufactured and easily as- 10 sembled. Other objects are to provide the roof with insulating airsp'a-cesv and to 'provide an insulating lining for the underside of the roof.' The invention consists princi-y pally inincreasing the-strength andrigidity 15 of the roof by means of upperand lower sheets that are rigidly'secured/together and to'the'side plates; it'alsovcons-ists in shaping and arranging the lowerv sheets -to provide air insulating spaces therein it also consists 2b in securing an insulating` lining to the underside of theroof; and it alsoconsist'sin the construction and arrangements of partshereinafter described and claimed. In the accompanying drawings, wherein y 2'5 like symbols refer to like vparts wherever they occur, A j v Fig. 1 is a plan view vof-a portion ofthe car roof embodying my invention;v Fig. 2 isan enlarged cross-section through one-half of the roof on the line 2-2 in Fig; 1, y 1 f Fig. 3 `is a vertical `longitudinal vcrosssection through the roof on the line 3^-3 in Fig. 1, j

According to the present invention,I the metal roof comprises upper and lower roof sheets 1 and 2, respectively', which lare pitched or arched from side plate 3 to sidewplateV 3 and have their ends turnedrdown and rigidly secured together and to the outer faces of the upstanding inner flanges of said side plates 'flat sheets that are overlapped along their vertical transverse Vby rivets 5. The upper roof sheets 1 comprisev adjacent side marginal portions andrigidly secured together byrows of rivets 6.. The

The inbottoms ofthe filler strips l10 by meansof nails ,12.` The filler strips 10 are preferably Vdeta'ch'ablv `secured within'the hollow ribs or'seams 8 of thelower roof by means of carriage bolts13 that are suspended from straps or clips 14 located inside offsaid ribs or seams andv securedxto the top walls thereof by the securingrivets 6 therefor. These bolt holder clips 14 of the seams 8 are located adjacent to the ridge and vthe eaves with their ends v'which connect the lower roof sheets 2,together and tothe upper roof sheets 1, are

By the arrangement described, a considerable amount of metal is massed in the upper portion oi' the roof where it operates to increase the load carrying capacity of the roof. The roof is further stitlened and strengthened by the hollow box girders formed between the seams that connect together the lower series of roof sheets; and said box girders also form air insulating spaces between the upper and lower roof sheets. The hollow seams also serve to accommodate the nailing strips for the. wooden lining, which operates to further insulatetlie roofgand these nailing strips also serve to further increase the strength and rigidity of the roof.
Obviously, my invention admits of considerable modification in the design of hollow seams that connect the lower roof sheets, and I do not wish to be limited to the speciiic design illustrated. Y
