CAR.

Specification of Letters Patent.

Application filed May 22, 1912. Serial No. 698,956.

To all whom it may concern Be it known that 1, JOHN J. TATUM, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improve ments in Cars, of which the following is a specification.

The object of my invention is to so construct a car roof that the individual roof sheets are-free to move relatively to each other without tearing under the strains and stresses to which a roof is subjected owing to the weaving of the car in transit, and

at the same time maintain water tight: joints between the sheets and between the sheets and the flashing at the eaves of the car.

A further object of my invention is to have the roof sheet-s extend over the eaves of the car onto the side thereof, but form a loose joint with the flashing along a line short of the caves of the car; and with these and minor objects in view, my invention consists of the parts and combination of parts as will be hereinafter pointed out.

In the drawing, Figure 1 is a perspective view of a car, broken away, er nbodying my invention; Fig. 2 is an enlarged detail sectional view, and Fig. 3 is a perspective View of a roof sheet constructed according to my invention.

The reference numeral 1 represents the side plate, 2 the side sheathing, 3 the carlinc, 4 the roof sheathing, 5 the fascia, and G the side post of a car which may beof any approved construction. I prefer that -the fascia be constructed with a lower thickened base as shown, because it 1s adapted to protect the fascia and the outer ends of the roof sheet from being damaged by cornering or side wiping but of course it will be understood that this particular construction of fascia is not necessary to the successful use of my present invention.

The flashing 7 is secured to the fascia or side wall of the car by nails or any other suitable fastening and extends onto the roof of the car back from the eaves, covering the joint between the side plate, the side sheathing and the fascia, and is rebent upwardly as at 8, the rebent portion being'spaced from the body portion of the flashing.

The roof sheets 9 are rebent under intermediate their ends along a line short of the caves of the carto form an open hook-like member 10 spaced from theunder face of the roof sheet, the outer end 11 of the sheet extending down over the eaves of the car and overlying the'flashing as shown to prevent water, snow and cinders entering between the portion 11 and the flashing. In the event 'of water being blown between the flashing and the portion 11 of the roof sheet, it will be prevented from passing under the main body of the roof sheet by coming into contact with the rebend 8 of the flashing which acts as a dam to prevent the water from further inward movement, and together with the pitch of the car roof will cause the water to run back over the eaves of the car. .The hook 10 of the roof sheet, the rebent portion 8 of the flashing and the main body of the roof sheet are spaced from each other as shown, to prevent water, etc, from creeping from one to the other, thus effectually preventing it from getting between the roof sheets and the roof sheathing 4 and entering the car and damaging the contents thereof.

The joint between the flashing and the roof sheets is a loose one, as will be seen Patented Feb. 17,1914.

from the drawing, which permits the sheets to move longitudinally of the car, but at the same time securely anchors them to the car along a line short of theeaves of the car. The side edges of adjacentroof sheets are joined'together by a loose joint short of the caves of the car as shown, whereby the sheets are free to move transversely of the car. As will be seen from the drawing, while I extend the ends of the roof sheets over the eaves of the car, they are secured by a loose joint to the car short of the eaves, so that in the event of the flashing becoming damaged, the end 11 of the roof sheet constitutes a waterproof covering over the joints between the side plate, side sheathing and the fascia. The portion 11 of the sheet being superimposed over the flashing will naturally receive snow, rain, etc, and in the event of a high wind, the snow, rain, etc.,

will be blown under the underbent portion of the sheet, but will be prevented from entering the car as the metal is continuous from one end of the sheetrto the other in cluding the under bent portion. Thus it will be seen that the loose joint between the roof sheets and the flashing is protected against the elements by the construction of the sheet. By formmgtheloose joint'between the flashing and the roof sheets short of the eaves of the car, it is more fully protected against rupture, than it would be if it were on the side of the car or at the eaves.

1. In a car, the combination with the roof sub-structure, of roof sheet having a return under bend short of its outer ends, said outer ends being bent down over the eaves of the car, and a flashing extending under the roof sheet and terminating at its inner end in an upper return bend constructed to, engage the return under bendot' the roof sheet and form a loose joint therewith.

2. A car roof comprising roof sheets, the outer end of each of which is rehent on the underside to form an inwardly opening pocket and thence rcbent outwardly and downwardly over the caves of the car, and a flashing mounted on the side of the car and bent over on top of the car with its inner end rebent on the upper side and interlocking with said pocket.

3. A car roof comprising roof sheets, the outer end of each of which is rebe nt under short of the caves of the car to 'form an open hook spaced from the under face of the roof'sheet, the end portion of the sheet hea hook spaced from the under face of the roof. sheet, said portion being rebent under the hook and extended across the top of the car wall and bent down on the side of said Wall, and a flashing secured to the side of the wall ,and extending under the roofing sheet and rebent at its inner end to form a hook interlocking with the hook on the sheet.

5. A car roof sheet bent. under and thence forwardly in the direction of length of the sheet, the outer edge of the sheet being bent downwardly and constructed tooverlie a flashing on the side of a car.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN J. TATUM.
