To all whom it may concern:

Be it knownthat we, WILLIAM A. BREWER, a citizen of the United States, and a resident. of the city of Pittsburgh, county of Alleghen andState of Pennsylvania, and GUs'rAvE A. GRUnNnnINo, a citizen of the United States, and a resident of the city of New Kensingtom county of Westmoreland, and State of Pennsylvania, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification. 1

This invention relates to outside metal car roofs of the type wherein there are a plurality of metal roof sheets. movably mounted on the substructure and extending from eaves to ridge on opposite sides of the ridge and loosely connected along'their side margins, and having their spaced ridge margins movably connected by means of ridge caps. a

One of the principal objects of the present invention is to hold the adjacent ridge corners of the roof sheets together without the use of the four-way corner caps heretofore used for this purpose. Another object is to close the eaves ends of the side seams and thereby eliminate the hood castings heretofore used for covering the open eaves ends of the side seams. Another ob,- ject is to improve the mounting of the endmost roof sheets so that these sheets will be free to shift on the car and accommodate themselves to distortions of the car substructure while in service. Other objects are to provide means for holding the adjacent ends of the ridge caps down on,

the car; to provide a weather-proof joint between the adjacent ends of the ridge caps and the running board saddles; to provide a desired degree of rigidity for the overhanging portions of the end sheets; and to provide for ease in assembling the roof on the car. i The invention consists principally in improved means for movably securing the ridge corners of the roof sheets to the roof substructure; in making the side seams with hooded end portions; and in making the end sheets with down-turned stiffening flangesat the outer side margins overhanging the car end- The invention further consists in the manner of securing the ends of the ridge Specification of Letters Patent.

The substructure of the roof shown in the drawing is of usual construction and comprises side and end sheathing 13 and 1-1;, side and end fascia boards 15 and 16, and roof sheathing 17 which is supported at the eaves on side plates 18, at the end of the car on end plates 19 and at the ridge by means of a ridge pole 20; Metal roof sheets 21 extend from eaves to ridge on opposite sides of the ridge in alinement crosswise of the car, and are each provided at one side margin with an upstanding flange 22, which is re-bent inwardly and downwardly at its top over the body portion of the roof sheet. The opposite side margin of the roof sheet is provided with an upstanding flange 23, which is bent outwardly and downwardly from its top at an inclination, and then re-bent or hooked upwardly and inwardly for a short distance. By this arrangement, the inwardly bent flange 22 at one side margin of the sheet can be telescoped into the adjacent. outwardly bent flange 23 of the adjacent side margin of the next sheet, thus forming an interlocking flexible seam connecting the side margins of the sheets. The lowermost or hooked portion of the outwardly bent flange 23 of one sheet clears the body portion of the adjacent sheet and is slightly lower than the lower edge of the inwardly bent flange 22 of the adjacent sheet, thus forming a neat sliding fit between these two interlocking flanges. The eaves end of the outer flange 23 of the side seams is provided with a hooded portion 24, which is open at the bottom and projects far enough beyond the eaves edge of the sheets to permit the escape of cinders, water or other matter which may enter the side seams. This hood portion also closes the end of the side seams and prevents water or cinders from blowing in the eaves endsof the seams.

The ridge margins of the sheets are provided with upstanding flanges 25, which are re-bent inwardly and downwardly from their tops over the body portions of the sheets in a manner similar to the side flange 22 of the sheets. The rebent or inclined portions of the flanges 22, 23 and 25 are cut away for a short distance from the ridge corners of the roof sheets, but the up-standing or vertical portions of the flanges 22, 23 and extend to the corners of the sheet, and the surplus metal at the corners is folded around as at 26, as shown and described in P. H. Murphy Patent No. 915,205 dated March 16, 1909. This arrangement produces solid corners and pre vents any leakage at the corners of the sheets.

The eaves ends of the roof sheets are' loosely held down on the roof substructure by means of a. continuous angle flashing strip 27, which rests in a shallow rabbet formed in the eaves end of the roof sheathing below the ends of the roof sheets and is turned down over the side fascia 15 and nailed or otherwise secured in place. The inner mar gin 28 of the flashing strip 27 is bent back over the intermediate portion of the flashing strip and spaced far enough therefrom to accommodate the doubled-under flange 29 of the roof sheets, thus movab-ly securing the sheet to the. car substructure.

The sheets are held in position at the ridge by means of channel-shaped corner clips 30. These corner clips are located along the ridge line of the car between the ridge ends of the sheets and at the ridge corners thereof. The side walls of these clips are bent outwardly and downwardly at their tops to form inverted U-shaped flanges 31, which fit over the end portions of the ridge flanges 25 of the four adjacentsheets which corner on each other. The downwardly inclined portions of the U- shaped side flanges 31 of the corner clips 30 are curved upwardly midway between their ends, as at 32, to clear the ridge ends of the upstanding flanges 22 and 23 at the side margins of the roof sheets. The corner clips fit snugly over the side and ridge seams, thus holding the four sheets together at the corners,

The corner clips are held in position by means of vertical bolts 33, which pass through their center portions and are secured to the ridge pole. These bolts also secure the running board saddles 34, to which the running boards 35 are nailed or other wise secured. These running board saddles are provided on their under sides with V- shaped longitudinal grooves 36, which fit over the side seams of the roof sheets. These running board saddles are also channeled crosswise on their under sides at their middle to permit the saddles to straddle the corner clips 30 and the oppositely disposed ridge flanges 25 of the roof sheets. The space between the ridge ends of the sheets is covered by metal ridge caps 37 of semicircular section, which straddle the spaced ridge flanges of the roof sheets and are provided with foot flanges 37 at each side which bear on the sheets on opposite sides of the ridge. These ridge caps are of less length than the distance between the side seams of the roof sheets and are provided with semicircular flanges 38 at each end, which fit into saw-cuts or slots 39 formed in the under side of the running board saddles.

The endmost sheets project a short distance beyond the end fascia l6 and their body portions are flanged downwardly, as at 40, and thence inwardly and upwardly at an inclination, as at 41, forming a stiffening flange along their outer side margins, which is spaced away far enough from the The doubled-under flange aoaaee over the end of the car with the flange 40 and thus forms a solid corner at-the outside corner of the end sheets. vThe end out the endmost ridge cap is turned down, as at 42, over the spaced ridge flanges 25 of the end sheets, and the end of the end ridge cap is held in position by means of a running board saddle 43, which is attached to the running boards 35 and straddles the end ridge cap. Unlike the saddle 34, this saddle 43 is not secured to the roof substructure. With this arrangement, the end sheets are free from the car except at the eaves, where they are loosely held by eaves flashing, and at the ridge, where the weight of the running board saddle 43 tends to hold the sheets and the end ridge cap in position on the car.

In the modification shown in Fig. 12, a spring clip 44: is shown secured to the end fascia of the car. This clip extends upwardly at an inclinataion and has its upper end 45 hooked into the in-turned flange 41 of the end sheets and, if desired, be used for holding the sheets down between the eaves and ridge of the car.

By the arrangement described, the roof sheets are held together in their proper positions on the substructure by means of the corner clips 30, while their spaced ridge ends are covered by the ridge caps, which, in turn, bear on the roof sheets and are held firmly in position by means of the running board saddles 34 and 43. This arrangement at the ridge of the car results in a waterproof ridge construction and does away with the necessity for the four-way corner castings heretofore used for holding the sheets at the ridge. The hooded eaves ends of the side seams, which project out beyond the end of the roof sheets, permit water and cinders that may accumulate in the side seams to flow out beneath the overhanging hooded portions, while these hooded portions also close the ends of the seams and prevent Water and cinders from blowing into the ends of the'seams. This does away with the hood castings heretofore used for this purpose. The endmost sheets are free to shift on the car; and the turning down of their outer side margins together with the doubled-under eaves portions greatly stiflens the overhanging outer edge and also prevents water from being blown under the ends of the sheets and entering the car.

The invention is not restricted to the precise forms and arrangements shown inv the drawings.
