' Application filed J une 27, 1918. Serial No. 242,275.

To all whom t may concern:

Be it known that I, WALTER P. MURPHY, a citizen of the United States, and a resident of the city of New York and State of New York, have invented a new and useful Improvement in Car-Roofs,. of which the following is a specification.

My invention relates to metal car roofs, and has for its principal objects to enable such roofs to accommodate the various distortions arising from the rackin and weaving of the car, and to provide ashings for the sides and ends of the car which will be capable of relative movement when the car goes out of square.

The invention consists in an end flashing strip whose ends loosely interlock with the eaves iashing strips. The invention further consists in the parts and combinations of parts hereinafter described and shown.

In the drawings, which form a part of this specication, and wherein like reference numbers indicate like parts in the several views:

Figure 1 is a lan view of the end portion of a car roof em odying my invention;

Fig.v2 is an end elevation of the upper portion of a car, showing the end sheet securing means;

Fig. 3 is a view similar to Fig. 1, the end sheet caps and a portion of one of the roof sheets being broken away.

Fig. 4 is an end elevation of the ridge portion of the car showing the weather-proofing means for the meeting ends of the end sheet caps;

Fig. 5 is a view similar to Fig. 4, the end sheet caps being removed and a portion of the end ashings being broken away;

Fig. 6 is a cross-sectional view on the line 6-6 of Fig. 4;

Fig. 7 is a cro-sectional view on the line 7-7 of Fig. 1;

Fig. 8 is a cross-sectional view on the line 8-8 of Fig. 1;

Fig. 9 is a cross-sectional view on the line 9-9 of Fig. 3;

Fig. 10 is a diagrammatic view showing the end flashing and the manner of connecting it with the eaves iashing;

Fig. 11 is a plan v1ew of an end portion of a car having steel end plates showing a modiied form of my invention applied thereto;

Fig. 12 is an end View of the roof shown in Fig. 11;

Fig. 13 is a plan view similar to Fig. 11, the end sheets-caps, fasteners and hood casting beinor removed;

Fig. 14 is a vertical cross-section through thev hood casting at the ridge of the car on the line 14-14 in Figs. 11 and 12; and

Fig. l5 is a vertical cross-section through the end portion of the car near the eaves on the line 15-15 in Figs. 11 and 12.

The roof shown in Figs. 1 to 10 of the drawings comprises metal sheets 16, extending transversely of the car from eaves to ridge, the sheets at one end of the car only being shown. The roof sheets 16 are shown as resting loosely on sheathing boards 17,

but the sheathing boards may be omitted.

The ridge ends of roof sheets are connected by standing seams 18. Theside margins of adjacent sheets are connected by similar seams 19.

Eaves fiashings 20 of angle. section are secured along the upper margins of the side fascia plates 21 of the car. The outer end portions of the sheathing boards 17 are rabbeted to receive the fiashings 20.` The inner margins 22 of the lashings 20 are bent back in a plane parallel to the body. of the ashing and substantially flush with the surface ofthe sheathing boards 17. The ends 23 of the roof sheets are bent under so as to interlock with the eaves flashings.

End lashings of angle section are secured to the upper margin of the ends of the car or to a fascia board 24 secured to the upper margin of the end of the car. Each of these iashings comprise a middle or ridge strip 25 and end strips 26. The end strips 26 extend the greater portion of the distance from the eaves to the ridge and have their outer end portions 27 turned under to interlock with the back turned portions 22 of the eaves iashings 20. The middle or ridge strip 25 is shaped to follow the contour of the ridge vportion of the car end. Its ends overlap the ends of the strips 426. vThe sheathing boards 17 adjacent to the car end are rabbeted to receive the end flashin strips. The inner margins 28 of the end ashing strips 25 and 26 are rebent. The outer margins of the end roof sheets proyect beyond the margins 28 of the Flashing strips. Sheet metal caps 29 of angle section are arranged on each side of the ridge seam and are nailed or otherwise secured to theends of the car. The inner margins of the caps 29 are bent under and bear against the roof sheets 16. The caps 29 have oorrugations 3Q at intervals to stiffen them. The corrugations 30 stop short of the inner bearing margins of the caps 29. Hood castings 31 are arranged over the adjacent ridge ends of the caps 29. The hood castings 31 are secured to the ends of the car by nails 32.

In Figs. 11 to 15 the end flashing is shown applied to the end portion of a car having metal angle bar end plates 34. In this constructionthe. flashing and end sheet cap are held in position by means of angle clips 35 located between the ridge and eavesof the car and by ahood casting 36 at the ridge. The clips 35 and hood casting 36 are secured to the end plate 34 by bolts 37. These bolts extend downwardly through upstanding bosses 38 formed in the ridge strip 25 and end strips 26 of the flashing and thence through the roof sheathing and top horizontal leg of the end plate where they are secured by nuts. The downwardly depending flanges of the flashing strip and end sheet caps are not secured as in the construction shown in Figs. 1 to 10,' these flanges being held in shape by the downward extending portions 39 and 40 of the cllps and hood casting respectively. The bosses 38 of the end flashing prevent leakage around the bolt holes and prevent clamping of the sheets when the bolts are tightened. These bosses also raise the end sheet up to the necessary level, and prevent tilting of the same, thus keeping the edge of the cap lying on the roof sheet in close Contact therewith. Ii water or cinders get under the end sheet caps, they are prevented from entering the car by the end flashing construction, and will escape through the corrugations in the downturned portions of the end sheet caps. The end flashing construction makes it possible to have the flashing fit properly, even when the dimensions of the car vary slightly froml the dimensions specified. The arrangement at the eaves, whereby the ends of the end flashing strips and of the roof sheets coperate with the back turned margins of the eaves flashing strips 'accommodates the unavoidable relative movement as between the sheets and the substructure and between the sides and ends of the car, and at the same time keeps the roof weatherproof.

' It is evident that the flashing construction described may be used with other forms of roofs than the one shown and that' other changes may be made without-departing from the invention; and I do not wish to be limited to the construction shown, exceptv as defined by the claims.

What I claim is:

1. A metal car roof comprising roof sheetsl arranged transversely oi" the car and having rebent eaves portions, eaves flashings having rebent portions cooperating with the rebent eaves portions of the roof sheets, and an end flashing for said car, the eaves ends of said flashing being rebent so as to coperate with the rebent portions of the eaves flashings.

2. An end flashing for a car roof -comprising overlapping strips of angle section having their horizontal portions resting on the end portion of the car andhaving their vertical portions overhanging the end of the car, the portion of-said ashing resting on the car being provided with a series of upy standing bosses. 3. A metal car roof comprising roof sheets arranged transversely of the car and having rebent eaves portions, eaves flashings having rebent portions coperating With the rebent eaves portions of the roof sheets, and an end flashing for said car, said end flashing comprising end members and a middle member, the adjacent ends of the said lmembers overlapping.

4. A metal car roof comprising roof sheets arranged transversely of the car and having rebent eaves portions, eaves flashings having tions adapted to loosely engage the rebent ortions of the eaves liashings.

6. g metal car roof comprising roof sheets arranged transversely of the car and having rebent eaves portions, eaves iashings having rebent portions coperating with the rebent eaves portions of the roof sheets, and an end liashing for said car, said end yflashingcomprising overlapping strips of angle section, the endmost strips of said end flashing being connected to said eaves flashings.

A metal car roof comprising an end roof sheet, an end flashing arranged `beneath said sheet and having bosses formed thereon, an end cap for said end sheet and end Hashing, and mea-ns for securing said end liashing and cap to the car, said means extending through the end cap and bosses of the flashing for securing the same to the car.

8. A metal car roof comprising an end roof sheet, an end ashing arranged beneath land end sheet cap to the car, said end sheet cap being supported on the bosses formed in the sectional end ashing.

9. A metal car roof -comprising an end roof sheet terminating a short distance from the end of the car, an end fiashing member extending beneath the end portion of said sheet for supporting the same, said iashing member being turned down over the end of the car and having a series of., bosses formed thereon between the margin of the end sheet and the end of the car, and an end cap for said end sheet and flashing member, said cap overlapping the end portionsof the end sheet and being supported on the bosses formed in the flashing member whereby the cap is raised so as to prevent binding of the end sheet. v Signed at'Chicago, Illinois, this 20th day of June, 1918.
