CAR-RJOOF.

QPECIFIOATION forming' part of letters Patent N 0. 718,145, dated January 13, 1903.

Application filed May 19,1902. Serial No. 108,006. (No model.)

To add whom it may concern;

Be it knownthat 1, JAMES J. MCCARTHY, a citizen of the United States, residing at Ohicago, in the county of Cook-and State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to roofs,and has particularly to do with metallic roofs for cars and other structures.

One of the objects of my invention is to pro vide an improved construction of metallic roof, which will be well adapted for use in eX- .eled, as shown in Figs. 3 and 4, so that they posed situations-that is to say, where the metal roof is not covered by a wooden roof, as is usually the practice in car construction.

A further object is to provide an improved metallic roof which will be so constructed as not to be damaged by wrenching strains-of the car-body. V

I accomplish these objects as hereinafter described and as illustrated in the drawings.

What I regard as new is set forth .in the claims.

In the accompanying drawings, Figure l is a partial perspective viewillustrating my improved car-roof. Fig. 2is a cross-section of a roof embodying my improvements. Fig. 3 is an enlarged detail, being a cross-sectional view showing one of the eaves of the car, illustrating the manner of securing the side edges of the roofing-plates. Fig. 4 is an enlarged detail, being a sectional view through the eaves opposite the doorway. Fig. 5 is a sectional view of the roof at one of the ends of the car; and Figs. 6, 7, 8, and 9 are sectional details illustrating the manner of connecting adjacent roofing-plates, showing the different steps of theoperation.

Referring to the drawings, lOindicates the sides of the car, and 11 the ends thereof.

12 indicates the doorway.

lins.

15 indicates a board roof which is carried by the purlins in the usual way and is adapted to support the metal roof, as hereinafter described.

16 indicates the metal roof, and 17 the runhing-board.

13 indicates the carlines, and 14 the pur- 18 indicates the side plates, which are arranged in the usual way.

As best shown in Fig.2, the roof 15 projects a short distance beyond the sides of the car, and under such projecting portions 19 are placed facia-boards 20, which are placed a short distance from the sides of the car, as best shown in Figs. 3 and 4c. This arrange- 'ment is secured by placing blockszl between the facia-boards and the siding, thus forming recesses 22 between the upper portions of the facia-boards 20 and the siding of the car, as shown in Figs. 3 and 4E. The inner upper edges of the facia-boards 20 are bevdo not positively engage thee'nds of the roofing-plates, as would be the case if a square corner were formed and the ends of the roofing-plates were bent down over such square corners. The-beveling of the -facia-boards prevents a positive or relatively unyielding contactbetween the inner corners ofthe faciaboards and the ends of the roofing-plates. Consequently the movement of the faciaboards cannot possibly be transmitted to the roofing-plates, which are therefore relieved from any possible wrenching strains.

The construction above the doorway is shown on a larger scale in Fig. 4, from an inspection of which it will be seen thatowing to the necessity of making provision for the sliding door instead of using the thin blocks 21 I provide thicker blocks 23 at suitable points at opposite sides of the door-space, so that the faciaboards 20 are held at a greater distance from the sides of the car than at other points. (See Fig. 1.) The manner in which the facia-boards are secured in place is not essential, as all that is necessary is to so secure them as to provide recesses 22 to receive the ends of the roofing-plates.

As illustrated in Fig. 1, the metallic roof is composed of a number of roofing-plates 24, which extend from one side of the car to the other and are connected together so as to form water-tight joints. In order to secure satisfactory joints, I'em ploy the construction illustrated in Figs. 6 to 9, inclusive. From an inspection of Fig. 7 itwill be seen that the adjacent edges a b of the roofing-plates are bent upward, so as to lie parallel with each other and spaced a short distance apart. Between the adjacent edges a b ofeach pair of roofing-plates lies a thin intermediate plate 25, as best shown in Fig. 7, which plate has an edge bent at right angles, as shown at c in Figs. 6 to 9, inclusive, which edge is secured to the board roof by nails or screws 26 and lies under one of the metal roofing-plates. When the parts are assembled and before the joint is formed, they occupy the position shown in Fig. 7. When the parts are thus assembled, the upper portion of the plate 25 with the adjacent edge I) of one of the roofingplates is bent over the upper edge a of the other roofingplate in the manner shown in Fig. 8. The upwardly-projecting parts are then foldedagain, in the manner shown in Fig. 9, so that the upper portion of the edge a is bent over and lies outside of and incloses a portion of the edge I) and the upper edge of the plate 25. In order to compensate for the shortening of the plate 25 and edge 5 by bending in the mannerdescribed, the parts are made of different lengths-that is to say, the upturned edge I) is made longer than the upwardly-projecting portion of the plate 25, the latter in turn being longer than the upturned edge a. By this construction the adjacent edges of the roofing-plates are firmly locked together and are also firmly secured to the wooden roof through the plate 25. Furthermore, a very firm water-tight joint is thus secured.

At their lower ends the metal roofing-plates 24 are provided with projecting ends, which are bent over the side edges of the wooden roof, as shown in Figs. 3 and 4, and project into the recesses 22, lying in contact with the beveled portions of the facia-boards 20, as shown. The ends 26 of the roofing-plates lie loosely in the recesses 22, so that wrenching strains of the car-body are not com municated to them. The metallic plates at the ends of the roof are secured by bending their side edges down over the end facia-boards 27 andsecuring them thereto by nails or screws 28, as shown in Fig. 5.

By this construction I provide a very secure metallic roof, which is not only watertight, but is also so secured in place as to be capable of adapting itself readily to wrenching strains, and consequently is not readily damaged.

7 That which I claim as my invention, and desire to secure by Letters Patent, is

1. In a car-roof, the combination ofsupporting devices, roofingplates carried thereby, said roofing-plates having projecting ends, and facia-boards secured to the sides of the car below the supporting devices, the upper ends of said facia-boards being slightly removed from the sides of the car, thereby forming recesses adapted to receive the ends of the roofing-plates, substantially as described.

2. In a car-roof, the combination of supporting devices, roofing-plates carried thereby, said roofing-plates having projecting ends. and facia-boards secured to the sides of the car, the upper ends of said facia-boards being slightly removed from the sides of the car, thereby forming recesses adapted to receive the ends of the roofing-plates, the upper inner edges of said facia-boards being beveled, to prevent the wrenching strains of the carbody being imparted to the projecting ends of the roofing-plates, substantially as described.

3. In a car-roof, supporting devices having portions projecting over the sides of the car, roofing-plates resting thereupon, said plates suitably attached to the supporting devices and having ends extending over the projecting portions of the said supporting devices, and side facia-boa rds arranged below the projecting portions of the supporting devices and forming recesses at the eaves of the car, said ends of the roofing-plates extending within the recesses and between the projecting portions of the supporting devices and top of the facia-boards.

4. In acar-roof, supporting devices having portions projecting over the sides of the car, roofing-plates resting thereupon, said plates suitably attached to the supporting devices, and facia-boards beveled at their upper edges, said bevel extending inward and arranged below the projecting portions of the supporting devices and forming recesses, said ends of the roofing-plates extending within the recesses and between the projecting portions of the supporting devices and the beveled edges of the facia-boards.

5. In a car-roof, supporting devices having portions projecting over the sides of the car, roofing-plates resting thereupon, said plates suitably attached to the supporting devices, facia-boards beveled at their upper edges, said bevel extending inward and arranged below the projecting portions of the supporting devices and forming recesses, said ends of the roofing-plates extending within the recesses and between the projecting portions of the supporting devices and the beveled edges of the facia-boards, and means for securing said facia-boards in position.

6. In a car-roof, supporting devices having portions projecting over the sides of the car, facia-boards suitably connected to the car, and roofing-plates mounted upon the supporting devices and having projecting ends, said projecting ends extending around the projecting portions of the supporting devices and between the facial-boards and the sides of the car.
