' Applicatibn iiled February a, m c. serial No. 745,821.

To all whom it may, concern Be it known that I, FRANK JAGER, a

citizen of the United States, and residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Metal Car-Roofs, of

which the followingis a specification.

My invention relates generally to roofing and has reference more particularly to im-- provements in metallic roofing plates in a railway freight car.

The principal object of my invention is to rovide a novel roofing construction for a reight car comprising a series of metallic plates adapted to be secured to car frame members in a manner more fully described hereinafter, whereby one or more of the series of plates may be readily removed for purposes of re air or replacement withoutinterference with or unfastening the other plates in the series. Another object of my invention is the provision of novel means in metallic roofing plates whereby the fastenings rovided to secure them to car members 0 not ass through outside sheets, and is thereby esigned to vided to pass through outside roof coverings and a, further object is to provide an improved metallic roofing comprising a series of sheets having-water tight jointsa't meeting edges, which at the same time are designed to permit sufiicient play of the platestherein to allow for twisting or weaving of through thermoof shown in Figure 1, and

Fi re 3 is a side elevation of Figure 2.

' 'gure 3 is a longitudinal section of a portion of the roof on a line adjacent to the ridge pole, and Figure 4 is a similar view but showin one of the plates given angular movement or'purposes of disengagement.

Figure 5 is a diagrammatic illustration of one of the' metal lanks which ultimately form one of the roofing plates A; and Figure 6 represents a view in perspective of one revent leakageof water around bolt hea s, ordinarily pro ing broken away to the of the plates. Figure 7 is a perspective of a portion of the plate taken from the left hand side of Figure 6.

Figure 8 is an enlarged sectional view illustrating the means for securing the saddle to the ridge pole.

In this class of car roofs, outer sheets of metal are usually employed and depended upon to make the roof water-tight. In fastening these sheets to car frame members, bolts or similar clamping elements are ordinarily used for urposes of attaching the sheets to the car frame members which support them, the bolts necessarily passing through the outer covering. Consequently as these bolts frequently Work loose, water collects around the bolt heads or nuts, and as a result leakage into the car occurs. To overcome this, numerous expedients have been devised involving the use of a number of detached or complicated parts which have many disadvantages incident to their use, among which may be. mentioned the tendency of such arts working loose and becoming lost, and also the great addition to the initial cost and subsequent maintenance of these roofs.

In maintaining these roofs, it is often necessary to remove a damaged or leaky sheet for the replacement of another. Carrying this out frequently. necessitates the removal "of the. entire series of roofing plates, by reason of the fact that some of these attaching parts cooperate with other parts of like character, or with other'p'lates, ,or with car frame members, so that one plate cannot be removed without removing others.

- With this in view, it is my purpose to provide a series of roofing plates having an inner depending flange formed integrally with the plates for-attachment to supporting frame members, and adapted to hold the joints forming the playroom at meeting edges of lates firmlyin place, any one or more of t e plates beingreadily removable without interference with other plates.

In describing my invention, the numeral 10 indicates the carlines, 11 the ridge pole, 12 the side plates,13 the car siding, and 14 the fascia, forming part of the car frame supporting the series of metallic roofing plates A runni from one of the eaves to ridge pole 1 and the series of metallic roofing-plates'B running to'the ridge pole from the other cave; their meeting side edges being" interlocked and meeting ends 40 ing web 50 plates overlapped at the ridge, substantially as shown in the drawings.

Each of the plates A is entirely formed I and pressed from a metal blank,'as shown in Figure 5 wherein the dotted lines indicate the line of bend, and is united to its adjacent sheets by a water-tight joint C comprising a broad rebent double fold 15 formed from the side edge of one sheet,

and a struck-up marginal flange 16 formed which receives the flange 16 ofthe adjacent sheet is of a breadth sufiicient to provide ample play therein for that sheet, and to permit its removal when given angular movement to a position substantially at rightalngles to the roof The web of each sheet is ressed short of its edge to form the double old 15, the marginal web being bent horizontally inward a short distance to provide an integral extension 17, which rests upon part of the upper surface of'a carline l0 bringing the joint C centrally thereof the web further continuing downwardly to form a do ending flange 18 provided with'slotted ho es 19 80 to receive bolts 20 for attachment to one of the sides of the carline '10. The plate A is preferably furnished with a downturned flange 21 overhanging but spaced it short distance away from the fascia to permit such transverse adjustment or play of the plates as afforded by the slotted holes 19. To prevent rain beating up into the open face of the joint at the cave, a dependinghood 22 is formed from a pro'ectortion of the blank and folded down as swam in the drawings to close the open face. At the end of the plate where it rests upon the ridge, I provide a rebent' margin 23 having pro ecting lugs 23 and 15 23 at its ends, which are bent inwardly to engage with the flange 16 and the double fold 15, thus aiding in retainin those members in position when. subjecte to pressure. 'The lates B have similar joints as the 3 iii, and (litter therefrom only in the struck up flan" e 24 at its meeting end which is adapted toie received within the rebent margin 23 of sheet A. It will be seen that I am. enabled by my invention to furnish a -001. of comparatively small cost as the separate metal plates of the roof can be cheaply made and readily assembled in position to form the car roof.

'Ilhe numeral 25 represents the saddles 50 which straddle and cover the joints C and rebent margins 23 at the points where they converge centrally of the ridge pole, this convergence allowing a clear opening at these points for passing the bolts 26 thro 5 the ridge pole and then through each sad. e;

tw en flange is uncoupled from within the car, the

saddle resting upon its double fold 1'5 and its section of running board is removed, then the sheet is given upward movement on an arc with the base of its flange 16 forming the axis of this movement until the sheet maybe slipped out. A portion of the rebent margin 23 of the plate A is cut away at the said. axial line, thus providing a clearance 31, designed to prevent possible binding on the struck up flange 24 of the adjacent sheet B. If a sheet B is to be taken outi there-- moval of the adjacent sheet A rea ily permits this to be done, without uncoupling additional saddles or sections as the axis of movement of both sheets A and i$.. .n the same axial line. To prevent any possibility of binding in the initlal movement of either of the'sheets, the side of thesaddle nearest the axial line maybe slightly beveled if desired as at 32.

From the foregoing, it will be apparent that the entire construction is simple and economical, comprising the plates, saddles and run boards, wherein the fastening means "are entirely inclosed and so arranged as to permit ready removal of such plates as may be required. Furthermore the joints between sheets are water-tight and .yet are loose enough to permit the necessary play of the sheets. Other advantages will readily appear to those skilled in the art.

Having' thus described my invention and illustrated its use what I claim as new and desire to secure by Letters Patent is the following 1. In a car roof, the combination with a carline, of a metallic roof sheet rovided at one side thereof with a depen ing perforated shect-attaching-flange formed to project into the car, a portion of said flange being bent inwardly against the body portion of the sheet to form a substantially' horizontal bearing surface adapted to bear upon the upper face of the carline, and fastening means engaging said perforated flange for detachably connecting the sheet to the carline.

2. In a car roof, the combination with a carline, of a alurality of metallic roof sheets side edge of one sheet and a double folded portion of inverted U shape on the side edge of the adjacent sheet, said double folded portion being adaptedto fit over the struck up flange of the other sheet and provided with an integral shee't-attaching-flange depending from the joint for attachment to the carline, substantially as described.

3. In a car roof, the combination with a carline, of a plurality of metallic roof sheets disposed in the same plane and adapted to be united together at their side edges by high-standing joints composed each of a struck up flange on the side edge of one sheet and a double folded portion of inverted U shape on the side edge of the adjacent sheet, said double folded portion being adapted to fit over the struck up flange of the other sheet, and having a de endin sheet-attachingflange bent inwar ly an downwardly away from the joint to rest up against the upper face and one side of the carline.

4. In a car roof, the combination with a carline, of a metallic roof sheet provided at one side thereof with a depending web portion formed with an elongated slot and adapted to project into the car adjacent the carline, and a bolt loosely engaging said slot for connecting the sheet to the carline, the bottom edge of said sheet being flanged down over the car siding and spaced away therefrom to constitute a clearance therebetween, all so constructed and arranged as to permit limited relative play of the sheet in a horizontal plane, substantially asdescribed.

5. In a car roof, the combination of a pair of adjacently positioned metallic roof sheets having their body portions disposed in the same plane, each having a struck up flange at one side edge and a bent folded portion at the other side edge adapted to fit over the struck up flange of the adjacent roof sheet to form a high-standing joint therewith,the bent folded portion of one of the sheets being provided with a depending its joint with the other of the plates, sub- 7 stantially as described.

6. As an article of manufacture, a metallic roof sheet formed from a single metal blank and composed ofa body portion having flanged top and bottom edges, and pro-.

vided at one side edge with a. struck up flange and at its other side edge with a double folded rebent portion, said-rebent portion having an attaching-flange bent inwardly and downwardly therefrom to depend from the body portion at one sidev of the said rebent portion.

7. In a car roof, the combination with a removable saddle and a run board section, of an uter roof covering comprising me-' tallic roof sheets arranged in series to ex-- tend between the ridge and the eaves, the sheets being adapted to be united together at their side edges by high standing joints composed each of a struck-upflange on theside edge of onesheet and a folded portion on the side edge ofthe adjacent sheet, the meeting ends of said sheets being lapped over at the ridge, a sheet-attaching flange formed integrally with the sheet and'projecting into the car, and means passing through said flange for .detachably connecting the sheet to the car, uncoupling of which permits the withdrawal of the sheet sidewise away from its joint with the adjacent plate on removal of the saddle and the run board section, substantially as described.
