CAR-ROOF.

Application filed December 13, 1918.

To all whom 'it 'may concern Be it known that we, WILLIAM A. BREWER, a citizen of the United States, and a resident of the city of Pittsburgh, county of Alle gheny, and State of Pennsylvania, and En WARD F. HoPPEL, a citizen of the United States, and a resident of the city of New Kensington, county of IVestmoreland, and State of Pennsylvzuiia, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

This invention relates to flexible car roofs of the type shown in C. C. Murphy Patent No. 1,133,493 dated March 30, 1915 wherein the roof sheets are pivoted near their ridge ends to the roof sheathing and are connected along their side and ridge margins by flexible seams and it relates particularly to the ridge construction of roofs of this type. In roofs of said type, the running board saddles, which support the running boards, and

.the intermediate anchor saddles, which hold the roof sheets down on their respective pivv ots, are 'secured to the roof su'bstructure by ineens ot' bolts; and it is important that these saddlesbe kept tight at all times to secure a water tight roof. In actual practice, these wooden saddles sometimes become loose and permit leakage; and, among the conditions which contribute to this eiiect, are i the following: the rottingand wearing of the saddles around the bolt holes; the shrinking of the saddles. roof sheathing and ridge poles' and the loosening of the nuts on the saddle bolts during the service of the car. In roofs of said type, another practical disadvantage is that the wooden intermediate anchor saddles, which are recessed on their under sides to receive the bosses of the roof sheets, are liable to split in the region of the recesses and thereby permit the sheets to 'become disengaged from their pivots.

The principal objects of the present invention are: to improve the ridge construction of the car so as-to overcome the disadvantages hereinbefore mentioned; to eliminate the' intermediateV anchor saddles and ridge corner caps;` to improve the joints between adjacent ends of the ridge seam covers and the running board saddles; and to keep the verselylof the car, side by side, in two rows ridge seam covers in alinement. The invention consists in an anchor c lip for holding I the sheets in position at the rid e, and in the .improved joint between the ar )acent ridge Specification of Letters Patent.

Fig. 7 is a perspective view of one of the ridge cap connector plates;

Fig. 8 is a perspective view ofthe end portion of one of the ridge seam covers;

Fig. 9 is a perspective view of the ridge end portion of a transverse seam cover;

Fig. 10 is a vertical cross-section of the eaves portion of the roof, the section being takenthrough one of the transverse seam covers on the line 10v10 in Fig. l; and

Fig. 11 is a vertical cross-section of the eaves portion of the roof, the section being taken between transverse seams on the' line 11-11 in Fig. 1.

The roof illustrated in the accompanying drawings comprises roof sheathing boards 12 supported at the eaves by metal angle side plates 13, and at the ridge by means of a ridge pole 14:, all of any suitable construc-4 tion. T ev roof sheets 15 are arranged transon opposite sides of the ridge. The roof sheets are arranged in pairs on opposite sides of the ridge', the twosheets of apair' being disposed end to end in transverse alinement and spaced a art from the adj acent pairs along their side margins to permit mullions 16 to be laid between them. These mullions are arranged in alinement cross-wise of the car, extend transversely of the car from eaves to ridge on opposite sides of the ridge, and are of less width than the space between the side margins of the roof sheets.

The eaves ends of the roof sheets are turned under, as at 17,parallel with the body portion of the sheet but spaced therefrom far enough to accommodate the rebent inner portion 18 of a continuous flashing strip 19. The ashing strip 19 lies in a rabbet formed in the eaves end of the roof sheathing and is turned down over the eaves ends of the sheathing and angle side plate 13. The flashing strip 19 and the eaves ends of the roof sheathing 12 are secured to the side plate by bolts 10 (see Fig. 10) or other suitable securing means, which are preferably located under the eaves ends of the mullions 16. The side and ridge margins of the roof sheets are provided with inwardly hooked upstanding flanges 20 and 21. The side margins of adjacent roof sheets are covered by transverse seam covers 22 which are supported on the mullions 16 arranged between the spaced side margins of the roof sheets. These transverse seam covers are of inverted channel shape in cross-section and their side walls have inturned flanges 23 at the bottom which incline upwardly and interlock with the inwardly hooked upstanding side flanges 2O of adjacent roof sheets. The transverse seam covers extend from ridge to eaves and are held down at the eaves ends by bending the eaves ends 24 of their top portions down over the ends of the mullions and then turning said portions under the rebent inner portion 18 of the flashing strip 19. The top portions of the ridge ends of the transverse seam covers have flat extensions 25 which lap at the ridge and are perforated to receive the saddle bolts 26 of the running board saddles 27. Running boards 27al are secured to the running board saddles 27, which rest on the transverse seam covers 22 and are supported by the mullions 16, thus leaving the sheets free to move under the transverse seam covers.

Each pair of oppositely disposed roof sheets 1s pivoted to the roof substructure at the middle portion near its ridge end by means of a sheet metal pivot saddle 28. The pivot saddles straddle the ridge portion of the car and are provided near their ends with inverted cup shaped pivot bosses 29 which lit into :counterpart upstanding bosses 30 formed in the middle portion of the sheets near their ridge ends. The bosses 30 of each pair of oppositely disposed roof sheets are held in' engagement with the pivot bosses 29 of the pivot saddle 28 by means of a channel shaped anchor clip 31 which has the upper portions of its side flanges bent outwardly and downwardly over the adjacent ridge flanges 21 of the oppositely disposed roof sheets. These anchor clips are located on top of the pivot plate 28, and both of these members arc secured in place by means of a bolt which extends down through the rootI sheathing and ridge pole.

A ridge cover 83 similar in cross-section to the transverse seam covers 22, but of greater width, straddles the spaced ridge margins of each pair of roof sheets, and the lower edges of its side walls rest on the roof sheet and are rebent inwardly, terminating in upwardly inclined flanges 34. The side walls of the ridge seam covers extend from transverse seam cover to transverse seam cover and at each end their top portions have extensions 35 which project over the lapped extension 25 of the transverse seam cover to within a short distance on each side of the saddle securingbolt 26. The extensions 35 at each end of the ridge seam covers have npstanding flanges 36 at their ends which project into vertical saw cuts or grooves 37 cut in the under side of the running board saddles 27. y

The adjacent ends of the ridge caps are held in alinement by means of ridge cover connector plates 38 which rest on the lapped extensions 25 of the transverse seam covers and project a short distance into the adjacent ends of the transverse seam cover be-y neath the top portions ofthe same. The margin of the portions of the connectoiil plates which project beneath the adjacent end of the ridge seam covers are rebeiit to form stiffening flanges 39. The connector plates are held in position by means of the saddle bolts 26 which pass through holes surrounded by upstanding bosses 40 located in the center of the connector plates. The bosses 40 of the connector plates are drawn into the under side of the running board saddle when the nut on the lower end of the saddle bolt is drawn up tight. The connector plates2 which serve to keep the ridge caps in alinement, will also carry off water that may be blown in under the running hoard saddles and over the upstanding flanges at the ends of the ridge seam covers, while the upstanding boss 40, which projects into the under side of the running board saddles, prevents this water from 'following the bolt and reaching the interior of the car. The sheets are held in position on their pivots at the ridge by the anchor clips 3l, thereby eliminating the intermediate running board saddles heretofore used for this purpose. The sheets are further held down along the ridge by the wide ridge seam covers, which bear on the roof sheets close to the bosses. The transverse seamcovers ridge seam covers 33 are held against move- `ment: lengthwise of the car by the upstamling llanges 36 at their ends which fit into the grooves or saw cuts 37 in the under side of the running board saddles 27. By the arrangement described, even though the ruiming board saddles become loose, the water proofing qualities of the joints along the ridge will not be impaired.

The invention is not restricted to the particular shapes and arrangements of parts shown in the drawings.
