THOMAS NATHAN RUSSELL, OF CHICAGO, ILLINOIS, ASSIGLNOB. TO CHICAGO-CLEVELAND CAB. BOOFING CO., F CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS.

CAR-ROOF.

Application led August 19, 1915. Serial No. 46.287.

To all whom t may concern:

Be it known that I, THOMAS NATHAN Rossum., a citizen of the United States, residing in Chicago, in the county of- Cook and State of Illinois, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

The invention relates to outside car roofs, and more particularly to such roofs having a roof lining or insulation applied atthe under sides of the roof sheets. Under some climatic conditions and extremes of temperature change, and particular character of the load within the car, moisture withinA the car condenses and collects upon the under sides of the metallic roof sheets. This condition is commonly called sweating and it is the object of the present improvement to prevent such condition under any circumstances.

The invention comprises a structure of' the longitudinal members of the car roof frame, Vsuch as the ridge pole and purlins,

lwhereby said members are adapted t6 hold lines.

The invention further relates to all new features of-advantage, which are, broadly or specifically, inherent in my improved roof. i

The invention consists in the parts and combinations' thereof, hereinafter s et forth and claimed.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying of a portion of thereof on a larger sca1e.`

Fig. 4 is a similar section of the eaves portion kof the roof, on a still larger scale. Fig. 5 is a vertical section, of about full size, of a portion of the roof, taken longitudinally Specification of Letters Patent.

of the carA atl or near the ridge pole. Fig.'6 is a vertical sectional view taken longitudinallyof the car at or near'the ridge pole, showing aportionV of the roof at one end` Fig. 7 is a plan view of the carline. Fig. 8 is a side view of the same. Fig. 9 is an end view of the same. Fig. 10 is a plan view of one of the longitudinal members, such as the ridge pole or a purlin. Fig. 11 is a side view of the same; in Figs. 10 and 11-the middle portion of the member is broken away. Fig. 12 is a plan view of one of the roof sheets. Fig. 18 is' an which ar`e or ma)1 oe of what is known as Z cross section, having a vertical webr 1`, an inwardly extending top flange 2 and an outwardly extending bottom flange 3. The I side plates are united at the ends of tli'e frame by end plates 4 which may be arched to conform to the roof. The above described roof frame members are carried by Vposts or stakes and braces of struction.

5 is the side sheathing and 6 thee-nd sheathing.

7 indicates the cai-.lines arranged at suitable intervals along and vresting on the top flanges 2 of the side plates. The carline's are arched from side to side of' the car, and are formed with a bottom central web portion 8, from which extend upwardly side flanges 9. Each side flange terminates in a substantially semi-circular curved lip' or flange 10 having its concave side presented. downward.- At its ends the carline is.

formed with horizontal bottom seats 11 which are secured to the side plates'y by rivets or bolts 12.

At its ends the carline terminates in. vertical flanges 13 turned down over and at the under `sides of the side plates, each of said flanges 13 being perforated by a hole 14 for a rivet 15 which secures the carline to the side plate. `The flanges 9.and 10 terminate at the upper part of the flange 13, an! line with them the flange 13 conlines the adjacent ends of thedownturned eaves flanges 16 of thel roof sheetsf lagainst the side plate 1, said flange l() being re. cessed at 17 (Figs. 7 and 8) `to `fit foven and confine such eaves flanges. Between Ithe known conics carlines the flanges 16 are secured to the side plates by bolts 18.

19 is the ridge pole'v and 20 the purlins, belng longitudinal members of the roof frame, all of which members may be of the same construction, as seen in Figs. 10 and 11. They are shallow inverted channel irons having a middle web 21 riveted to the web 8 of the carlines at 22 and side flanges 23 located about a half inch below the web 21. The ends of these longitudinal members f are recessed at 24. to fit under the end plate flange 25 to which they are riveted (Fig. 6).

The roof sheets are shown at 26 and eX- tend from side plate to side plate, and are formed at their side edges with S-shaped flanges 27 which fit tightly Within the flanges or lips 10 of the carlines (Fig. 5).

28 is an insulation-supporting plate secured to the side plate, preferably by the rivets 12 and having. its inner edge spaced about one half of an inch from the under sides of the carlinles and roof sheets, the under sides of the latter being.v substantially flush` with each other as shown. The said insulation is shown at 29, being lpreferably in the form of tongued and grooved sheathing of about one half of an inch in thickness. This insulation extends substantially from side plate to side plate, arched to correspond with the arch of the roof (Fig. 3), but the same is not necessarily continuous.

As shown it is'made in two sections for each v side of the roof. The outer section is sup'- ported by i the inner sect1on being supported by the inner flange 23 of said purlin and the opposing flange 23 of the ridge pole; and the two sections at theA other side of the ridge are correspondingly supported.

30 is a {lashing having a hook flange on the top of the side plate and a vertical lange confined on the outer side of the side plate under the roof sheet flanges (Fig.- 4). The outer section of. the insulation abuts against the hook of the said flashing. In the absence of this flashing, and of the plate 29, the l outer edge of the insulation would rest on the top of the side plate. The insulation doesfnot necessarily sustain the roof. `It maystiffen it, but it is suspended at theunderside of the Water excluding members.

In the .construction illustrated the roof sheets are supported by the elevated m1ddle portions of the ridgepole and purlins, inde-v pendently of the insulation. But the inventiondoes not exclude a construction in which all portions of the longitudinal members are a. little (say one half inch) below the bottoms'd ofthe carlines, in whichcase the sheets would be supported'by the insulation, and the latter in' turn by the longitudinal members.

The parts of the insulation are preterably fitted .in place as the process of applythe plate 29 and the outer flange- 23 of the purlin,

ing the roof sheets in place proceeds. But` they mayA be sprung into place from below after the roof has been otherwise completed.

The said insulation is indirectly suspended from the carlines, and covers the under sides of the ro'oitl sheets and carlines, eXc'eptin where 1t is or may be interrupted by the lon g1tudinal members. i
