CAR ROOF.

Application filed :une 21, 1926. serial No. 117,331. y

My invention relates principally to that type of flexible outside metal car roof Wherein light gage rooting sheets are loosely connected along their adjacent margins by seam covers that permit relative movement of said root sheets to a limited extent in accommodating themselves to the distortions of the car body.

rlhe principal object of the present invention is an improved seam construction that will permit a limited sliding movement of the root' sheets transversely of said seam cover and will secure a sluing or oscillatory movement of said sheets in all positions of their sliding movement. Other objeets'are simplicity and cheapness of construction7 compactness and economy of design and ease of assembly.

The invention consists principally in loosely connecting adjacent sheets by means of a seam cover having separate sliding and pivotal connections with said sheets. The invention further consists in the parts and in the combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing which :forms part of this specication and wherein like symbols refer to like parts Wherever they occur,

Fig. 1 is a plan View ot' a flexible outslde metal car roof embodying my invention;

Fig. 2 is a transverse section through one of the side seams on the line 2 2 in Fig. r1;

Fig. 3 is a transverse section through the roof at the eaves on the line 3-3 in Fig. 1;

Fig. 4t is a fragmentary plan View, showing the slidable and pivotal connections between the ridge seam cap and the roof sheets;

Fig. 5 is a. vertical cross section through the ridge seam onthe line 5-5 in Fig. 4; and

Fig. 6 is an enlarged detail section on the line 6 6 of Fig. 5.

Referring to the accompanying drawing', my invention is shown in connection with a car having wooden roof sheathing 7 supported on side plates 8 and a ridge pole 9. Metal roof sheets 10 are arranged on` the roof sheathing 7 side by side in two rows on opposite sides of the ridge, the two rows of roof sheets being spaced apart at the ridge and the sheets in each row being spaced apart at their sides. The roof sheets on op- .the car and rest on the said battens.

inwardly and downwardly over the body portions of the sheets to form upstanding hook-shaped side and ridge seam flanges 12 and 13. The eaves ends of the roof sheets are doubled under to form hook flangesll that loosely engage the doubled over hook iianges 15'al of angle flashing strips 15 secured to the eaves oi the car, such arrangement serving to loosely'retain the sheets von the car at the eaves. The adjacent side seam flanges 12 of the sheets, together with the mullions 11 located therebetween, are preferably covered by inverted channelshaped transverse or side seam covers or caps 16 that extend from eaves to ridge of The side seam covers 1.6 have inwardly and npwardly extending hook flanges 17 at their lower edges that interlock with the upstanding side seam flangesy 12 of adjacent sheets. The eaves ends of the side seam covers are loosely held in position by extensions 16l that are turned down over the eaves ends of the mullions 11 and are thence turned under the eaves corners of the roof sheets and hooked into the doubled back iianges 15a of the eaves flashing strips 15.

Pressed metalridge seam covers or caps 18 of substantially inverted channel-shaped section straddle the spaced ridge langesl?, of adjacent sheets and have outstanding base flanges 19 that rest on the body portions of said sheets inside theridge and side seam ianges thereof. The adjacent ends of the ridge seam covers 1S and the transverse seam covers 16 are held in position on the car by means of the usual pan-shaped .tour-way corner caps 2O that are secured in position by means of vertical bolts 21, which also secure the running board saddles (not shown) in position.

The base flanges 19 ofthe ridge seam covers 18 are pressed upward midway of their length to form downwardly opening grooves 22 that extend transversely of said base flanges from side to side thereof. The two grooves on the under sides of the two base flanges of each ridge cap are disposed in alinement transversely of the cap and are made wider at their ends than at their mid: die, preferably by bowing' or curving their opposing side walls away from each other from end to end of said grooves to form opposing convex surfaces in the sides thereof. he ridge end portions of the body portions of the sheets are provided midway of their side margins with upstanding ribs 24 that extend transversely of the seam covers and are straddled by the downwardly opening grooves 22 in the base flanges thereof.

The width of the narrow middle portions of the grooves in the base flanges of the seam `covers corresponds to the width of the upstanding ribs 24 on the roof sheets, whereby said ribs have a snug fit in the said grooves midway of their length and are normally spaced therefrom at their ends.

By the arrangement described, the ridge ends of the sheets are properly centered between adjacent roof mullions by the rib and groove connections between the body portions of the roof sheets and the base flanges of the ridge seam covers; and said sheets are adapted to accommodate themselves automatically to the distortions of the car body by sliding towards and away from each other along the transverse grooves in the base flanges of theridge seam covers and by rocking upon the convex ofsaid grooves.

An important advantage of the above arrangement is that it secures a sluing or pivotal movement of the sheets around points located in the region of the middle of their ridge ends in all positions of their sliding movement. @ther advantages of the present construction are the cheapness and simplicity of the construction of the roof sheets and ridge seam covers and the ease with which they may be assembled on the car.

The invention is not restricted to the precise shapes and arrangements of parts shown and described.

1What I claim is:

l. A flexible car roof comprising roof sheets arranged on the car side by side, a seam cover covering adjacent margins of said sheets, and means on the marginal portions of said seam covers cooperating with means on said roof sheets for permitting sliding movement of said roof sheets transversely of said seam covers and sluing movement of said roof sheets on said seam covers in substantially all positions of such sliding movement.

2. A flexible car roof comprising roof sheets arranged on the car side by side, a

seam cover covering adjacent margins of said sheets, and means on each sheet cooperating with means on the adjacent marginal portion of said seam cover for permitting independent sliding n'iovement of said roof sheets transversely of said seam cover and preventing bodily movement of said sheets longitudinally of said seam cover.

3. A flexiblel car roof comprising roofI sheets arranged on the car side by side, a seam cover covering adjacent margins of said sheets, and means on said sheets cooperating with means on the marginal portions of said seam cover for permitting independent sliding movement of said sheets transversely of said seam cover, said cooperating means permitting independent-sluing movement of said sheets around points located in the region of their adjacent marginsand preventing bodily movement of said sheets longitudinally of said seam cover.

4L. A ftexible car roof comprising roof sheets arranged on the car side by side, a seam cover covering adjacent margins of said sheets, and tongue and groove connections between the body port-ions of said sheets and the marginal portions of said seam covers, said connections permitting independent sliding movement of said sheets transversely of said seam cover.

5. A flexible car roof comprising .roof sheets arranged on the car side 'by side, a seam cover covering adjacent margins of said sheets, and tongue and groove connections between the body portions of said sheets and the marginal portions of said seam covers, said connections permitting independent sliding movement of said sheets transversely of said seam cover, said tongue and groove connections also permitting independent sluing movement of said sheets relative to said seam cover.
