WILLIAM D. THOMPSON, OF DETROIT, MICHIGAN, ASSIGNOR TO HUTCI-IINS CAR ROOFING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

CAR-ROOF.

Application filed June 4, 1909.

To all whom it may concern:

Be it known that I, WILLIAM D. THOMP- son, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invente certain new and useful Improvements in Car-Roofs, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates particularly to freight car roofs, of the type known generally as inside metal roofs, consisting primarily of an upper and a lower framework of wood and an intermediate metallic covering, and the invention consists in the novel construction of a roof of this character wherein the metallic covering while properly held in place between the sub and superstructures is imperforate throughout, thus eliminating any liability of leakage.

The invention further consists in the peculiar arrangement and combination of the roof parts, and in various details of construction as will be more fully hereinafter set forth.

In the drawinges,-Figure 1 is a sectional perspective view, illustrating an embodiment of my invention; Fig. 2 is a similar view, enlarged, illustrating more particularly the spacing means for the fascia and retaining devices for the metallic covering; and Fig. 3 is a section taken on line aaw of Fig. 1.

In the drawings thus briefly described, A designates the substructure of the roof, con.- sisting of the usual carlines B, purlins C, and an inner ridge pole D. E represents the side plate, and F the sheathing constitut ing the car side.

The intermediate metallic lining or covering interposed between the framework is represented by the reference-letter G. This covering is composed of a plurality of metallic plates arranged one series upon each side of the ridge in the usual manner, with the adjoining sides of the plates united. The plates may be connected by any preferred type of joint that will produce a continuous covering, and I have here shown the joints as composed of overlapping angleshaped flanges a. Each plate at its lower end has a turned-down portion or flange b that bears against the car side, as plainly illustrated in Figs. 2 and 3.

Serial No. 500,182.

Mounted independently of and upon the metallic covering described is the superstructure H, composed of the usual subcarlines I, sub-purlins J, and an outer ridge pole K. The upper ends of the sub-carlines are adapted to be nailed to the inner ridge pole, as indicated in Fig. 1, while the sub purlins are nailed to the sub-carlines, the nails extending only into the carlines and not therethrough or through the sheet. In this manner, the metallic covering, while extending continuously over the sub-structure, is also imperforate, and any liabilitv of leakage is thus prevented.

To hold the superstructure in place and at the same time retain the metallic covering in its proper position upon the substructure, I

employ holding-down means at the eaves, consisting preferably of angle-shaped clips, as L. These clips are adapted to be inserted at their upper ends in recesses 0 formed in the upper faces of the lower ends of the subcarlines, and their depending portions 0? are of a length to extend downwardly below the flange 1) of the sheets, and contact therewith, and are retained at their lower ends to the car side preferably by lag-screws 0. These clips, as will be obvious from their construction and location, hold the substructure properly in position against longitudinal movement; hold the metallic sheets down upon the substructure, and at the same time constitute the spacing means for the usual fascia M, which is offset for the purpose of providing the usual drip opening or space extending longitudinally of the car.

0 represents the outer roof boards, which complete the superstructure, and P are the usual running boards.

The superstructure is designed to be supported entirely upon the metallic covering, and for the purpose of taking the wear off the metal sheets or plates, and of preventing their possible rusting by reason of their contacting with damp subcarlines, I preferably interpose between each subcarline and the metallic covering a strip of material Q, such as felt, of a length corresponding substantially to the length of the carline, as shown.

The usual provision is made by spacing the fascia for draining off from the sheet at its lower end any water that may leak through upon the metal. While the car is in motion, however, there is a tendency for such waterasfhas deposited u'pon -th'e' sheet to be thrown side'Wise' from carlin'e tocarline;

To arrest this movement of the Water and" prevent its contact with the Wooden subcarlines and thereby eventually rot the same, I preferably employ arresting strips, formed in this instance by extending the edge portions of the felt strips beyond each side of the Subcarline; as indicated. These project ing felt strips thus check theWater-andserve as guidesfor conducting the same down upon; the sheet to its lower endand independently of the car-line.

What I- claim as my invention is,-'

1. In a-car roof the combina'tion With the main framework, of an imperfora'te metallic covering; extending continuously thereover from-the ridge to theeaves,.a superstructure mounted independently of and supportedentirely upon the metal covering, afascia s aced to form a drip openin and angle clips at the eaves for holding down the superstructure and spacing the fascia.

2. The-- combination With a sub-structure, of a metallic covering independently mount ed thereon, a superstructure including carlines independently mounted on said metallic roofing and purlins mounted on said carlines, a spaced fascia, and angleclips at the eaves hayinga lateral portion positioned intermediate said carlines and said purlins, and a downwardly extendingv portion intermediate the fasciaaand' the car side;
