Application filed December 21, 1911. Serial No. 667,069.

To all whom may concern Be it known that 1, JOHN L. Morton, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Car-Roof Construction, of which the following is a specification.

This invention relates to car roof construction, and more particularly to what are known as outside metallic roofs in which the metal roofing sheets are laid upon the outside of the roofing boards.

One of the objects of my present invention is to provide improved means for preventing leakage, and for carrying off drainage water from the edges of the roofing sheets, and for this purpose, drain troughs are provided at the side edges of the roofing sheets, and at the ridge.

Another object is to provide an improved running board saddle construction adapted to connect with the drainage troughs and hold in place the caps for the same.

Another object is to provide improved hood connections for covering the ends of the drain troughs at the ridge and at the caves of the car.

In the accompanying drawings: Figure l is a transverse section of aportion of a car roof embodying one form of my improvement; Fig. 2, a transverse section of the running board saddle connection taken on the line 2-2 of Fig. 1; Fig. 3, a similar transverse section taken at the center of the ridge, the upper part of the saddle being broken away; Fig. 4C, a transverse section of a carline with roofing boards, metal roof sheets, drain trough and caps, taken on the line 4.-i of Fig. 1; Fig. 5, a transverse section similar to Fig. 3, but showing a slightly modified means for fastening the running board saddle; 6, a horizontal section with the top portion of the running board saddle removed and showing the connection of the saddle with the drain troughs; Fig. 7 a corresponding side view with the ridge trough, ridge pole, and roofing boards shown in vertical section; Fig. 8, a transverse section of the car ridge at a point be tween carlines; Fig. 9, an end view of the car rides nd hood f r ove ing th r g rough an ars Fis- "a lons' tud r lseci r; of the s me; ta er oa h lin l l of Fig. 9; Figs. 11 and 1 2. transverse seci s similar to F s- 2, bu s c n dif eren forms of car-lines; Fig. 13, a transverse sec tion showing a modified form of running board saddle in which a wooden block is t'astened to the upper casting; Fig. let, a transverse section of the saddle taken at the ridge; F ig. 15, a plan of the lower casting of the saddle showing the connections with the drain troughs; and Fig. 16, a plan of the upper casting of the saddle shown in Figs. 13 and 14.

The frame of the car roof may be constructed in the usual way by means of carlines, 20, resting on the side plates, 21, and carrying the purlins, 24, and ridge pole, 25, on which may be laid roofing boards, 30. According to my improvement, the roof may then be covered with metal roof sheets, 23, laid in sections, each of a width about equal to the distance between carlines or of any other desirable width, and between the side edges of adjacent sheets are located the drain troughs, 32-, preferably for-med of pressed sheet metal, the edges of the roof sheets being turned up over and down into the troughs so that any water which passes over the edge of said sheets will fall into the trough and drain off at the discharge from the trough over the side plate at the caves of the car.

The drain troughs, 32, and the turned over edges of the roof sheets are covered by the caps, 22, the lower ends of which are covered and held in place by the hoods, 60, bolted to the side plate of the car. The upper edges of the roof sheets at the ridge are turned over into a ridge trough, 26, which is covered by the ridge cap, 33, and supported on the roofing boards.

The running board saddle is preferably formed in two or more parts, the lower or inside part having trough shaped projections, 27 and 28, at rightangles to each other and adapted to fit the ends of the re spective drain troughs, 32, and 26, as shown more particularly in Figs. 6 and 7, of the drawing, and thereby constitute a continuation of said troughs, whereby drainage from the ridge trough, 26, may pass through the portion, 27,'of the saddle and oil through the lateral drain troughs, 32. As shown in ,Sheets 1' and2 of the drawings, the upper pa es, i9, o the addle may be formed h heri utal fl n to which the oar r atta hedfand two ve tical flanges dap d, t fit ov r an he lted o as vertit e-1 web, 29 of t e lowe portion of th saddle, said flanges being flared or pressed outward at the lower edge to cover over the ends of the caps, 22, and also shaped to fit over the ridge caps, 33, as shown. In this way the flanges serve to hold in place both the lateral caps, 22, and the ridge caps, 33, and form a continuation of the same. The saddle may be supported on the roofing boards or may be, provided with a flange, 31., extending through an opening in the boards, and bolted to the carline, 20. Any suitable or preferred form. of carline may be employed such as the U shaped metal section shown in Figs. 2 and 3, or a Z bar metal section, as shown in Fig. 11, or an ordinary wooden carline, as indicated in Fig. 12. "Where the roofing sheets are of such a width that the saddles are located between carlines. the saddles may rest upon the roofing boards ii lld be bolted to the ridge pole as shown in Where it is desired to use a wooden block or saddle for supporting the running board, the castings may be made much shorter and the upper casting, 40, may be provided with two lugs or flanges between which the wooden block or saddle, e0 is mounted, as fully shown in Figs. 13, 14, 15, and 16 of the drawings. In this modification, the projections, 27, of the lower casting, 4-0, are quite short, but connect with the lateral drain troughs, 32, while the projections, 98, connect with the ridge trough, 26, in the same manner as before described, for draining the water from the ridge trough through the saddle casting into the lateral drain troughs. The flanges of the upper casting extend out to cover the ends of the cap members and hold the same in place, as before described. The wooden block or saddle, 40*, may be securely fastened to the castings by means of a bolt shown, and the whole then bolted or otherwise secured to the ridge pole or carline as desired. This makes a very simple and cheap saddle construction.

For protecting and holding in place the ridge trough and caps at the ends of the car, I provide the ridge hood, 66, which covers the end of the cap, 33, and ridge trough, 26, and is bolted to the end plate of the car, thereby securely holding these parts in position, as shown particularly in Figs. 9 and 10 of the drawing. Any water that collects at the end of the ridge trough will thus drain off through the hood and over the end of the car.

It will now be seen that my improved roof construction herein described has the advantage that it may be applied to existing woden roofs, as well as to new cars, and provides a durable and rain proof covering for keeping the interior of the car perfectly dry, while at the same time being sufiiciently flexible to allow for the twisting and. bending movements of the car.

Having now described my invention, What I claim as new, and desire to secure by Letters Patent, 1s:

1. In a car roof, the combination with inside roofing boards, of metal roof sheets on the outer surface of said boards, metal drain troughs also located upon the outer surface of the roofing boards at the edges of the roof sheets, caps covering said troughs, and hoods for fastening the caps and covering the open ends of the troughs at the eaves of the car.
