MURPHY COMPANY, OF NEW KENSINGTON, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA CAR ROOF Application filed November 21, 1930. Serial No. 497,099.

This invention relates principallyto flexible car roofs of the kindwherein the metal roof sheets are connected by seam caps that extend from eaves to eaves of the car and consist of intermediate and end sections arranged end to end in overlapped relation so that said caps are applicable to cars of different width. It is the object of the present invention to prevent leakage between the ridge ends of the end sections of the seam caps. The invention consists in the sectional seam cap and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanyin drawings, which form part of this speciflcation and wherein like symbols refer to like parts wherever they occur,

Fig. 1 is aplan view of a portion of a flexible car roof provided with sectional seam caps embodying my invention,

Fig. 7 is a vertical transverse cross-section through said seam on the line 77 of Fig. 3,

Fig. 8 isa perspective View of the ridge end portion of one of the end sections of a seam cap; and i Fig. 9 is a sectional perspective view of a'portion of the ridge or intermediate section of a seam cap, the section being taken midway of the ends of said section.

Referring to the accompanying drawings, my invention is shown in connection with a l1 that bear 'flatwise on the upwardly incarline to carline and are bolted or other-' wise removably secured to the top flanges 2 of the side plates A. The roof sheets are supported between side plates by a ridge pole 4c and purlins 5 which extend longitudinally of the car beneath the carlines and are bolted to the base flanges 1 thereof. The roof sheets C have raised side marginal panels 6 that are inclined upwardly and terminate in upstanding side marginal seam flanges 7 that extend from end to end of said sheets. The roof sheets are also provided at their eaves ends with depending flanges 8 which overhang the webs of the side plates and terminate in inturned portions 9 that arespaced away from said webs.

Weatherprooflng members in the form of inverted channelshaped seam caps D straddie the carlines B and the side marginal flanges 7 of adjacent roof sheets with their webs bearing flatwise against the webs of the carlines and are rigidly secured thereto adjacent to the ridge andthe eaves by rivets 10. The channel-shaped seam caps D are provided with outstanding base flanges olined side marginal panels 6 of the roof sheets, thereby holding said sheets down on the car. 'The eaves end portions of the seam caps are provided with depending eaves flanges 12 which overhang and are. spaced.

from the ends of the carlines and the eaves corners of ad acent roof sheets and terminate in inturned portions 13 that are spaced away from the inturned ends 9 of the ver- 'tical webs of the side plates.

Running boards 14 extend longitudinally of the car at the ridge and are supported on the lateral top flanges of Z-bar running board saddles 15 whose lateral base flanges rest on the seam caps and are rigidly secured thereto by the rivets 10 that secure the ridge portions of said caps to the carlines.

The transverse seam caps D are made of a plurality of sections arranged end to end in overlapped relation so that said caps are applicable to cars of different widths. As shown in the drawings, said seam caps are preferably made in three sections: namely, duplicate end members or sections 16, which extend from eaves to points adjacent to the ridge, and a single intermediate or ridge section 17, which overlaps the ridge end portions of the two end sections. The ridge sections 17 of the seam caps D are preferably pressed outwardly adjacent to each end, as at 18, to provide a space between the overlapped portions of the ridge and end sections for strips of tar paper or other suitable material 19, which is dipped in paint before application. This arrangement provides a watertight joint between the overlapping ends of the cap sections.

In order to prevent leakage between the ridge ends of the end sections 16 of each seam cap D, the ridge end portions of the base flanges of said end sections are cut away or notched, as at 20, and the ridge or intermediate seam cap section 17 has its base flanges depressed, as at 21, to rest upon the side marginal roof sheet panels '6 within the notched ends of the base flanges of said end cap sections. By this arrangement, the base flanges of the ridge or intermediate cap section 17 of the seam cap bear flatwise upon the roof sheet panels 6 opposite the space between the end cap sections 16, thereby preventing water from entering the seam cap at points opposite the ridge ends of the end cap sections and being blown over the flange 7 of the roof sheets into the interior of the car. Although small spaces are left between the ends of depressed panels 21 and adjacent edges of the notches 20, it is noted that these openings are located opposite the end cap sections 16, instead of being located directly opposite the space between the ridge ends thereof, whereby said. end cap sections serve as baffles to prevent any water that enters these holes from reaching the roof sheet flanges and being forced thereover into the interior of the car.

The invention is not restricted to the precise forms and arrangements shown and described. 1

What is claimed is: V

1. A seam cap fora car roof, said cap com prising end and intermediate sections provided with outstanding base flanges, the adjacent ends of the base flanges of said end sections being provided with notches, the

base flanges of said intermediate cap section being provided with depressed portions adapted to seat within the notches in the base flanges of said end cap sections.

2. A transverse seam cap for a car roof, said cap comprising end sections and a ridge section overlapping the ridge ends of said end sections, said sections being of inverted channel-shaped cross-section with outstanding base flanges at the lower edges of their side Walls, the ridge ends of the base flanges of said end sections being provided with notches, and the base flanges of the ridge section being provided with depressed panel portions adapted to fit within the notches in the base flangesof said end sections.

3. A seam cap for a car roof comprising end sections and an intermediate section overlapping the adjacent ends of said end sections, said sections being provided with '1 outstanding base flanges, the adjacent ends of the base flanges of the end sections being provided with notches, and the base flanges of the intermediate section being provided with depressed panels adapted to cooperate with the notches in the base flanges of said end sections.

4. A seam cap for a car roof, said caps comprising end sections connected by an intermediate section adapted to overlap the adjacent ends of said end sections, said sections being provided with oustanding base flanges, the base flanges of the intermediate section being provided opposite the adjacent ends of said end sections with portions disposed in the plane of the base flanges-of the end sections beyond the outer edges thereof.

5. A car roof comprising roof sheets provided along their adjacent margins with upturned flanges, and seam caps straddling the flanges of adjacent sheets, each of said seam caps comprising end sections provided with outstanding base flanges that rest upon adjacent sheets, and an intermediate section overlapping the adjacent ends of said end sections and provided with outstanding base flanges overhanging the base flanges of said end sections, the adjacent ends of the base flanges 'of the end sections being provided with notches, and the base flanges-of said intermediate section being provided with depressed panels that fit within the notches in the base flanges of the end cap sections and bear upon adjacent roof sheets.

6. A car roof comprising roof sheets extending from eaves to eaves of the car and having upturned. flanges at their side edges,

and seam caps extending from eaves to eaves of the car and straddling the side marginal portions of adjacent sheets, each of said seam caps consisting -oil? end sections of inverted channel-shaped cross-section with outstanding base flanges that bear flatwise on the side marginal portions of adjacent sheets and are cutaway at the ridge ends of said sections, and a ridge section of inverted channel-shaped cross-section with onstanding base flanges, said ridge section overlapping the ridge ends of said end sections and having depressed panels in its base flanges that fit within the cutaway ridge ends of the base flanges of said end sections and bear upon the. side marginal portions of adjacent sheets.
