can-Root.

Specification of Letters Patent. Patented June 1912,

Application filed August 10, 1910. Serial No. 576,546.

To all whom it may concmmq Be it known that I, WALTER P; MURPHY, a citizen of the United States, residing at Chicago, 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.

In certain car roofs comprising metallicthey hold the sheets down on the substructure. This tendency. of the sheets to slide longitudinally causes a strain 'upon the nails, clips on other fastening means in the direction in which their-resistance is least, as t-h'e cli'ps tend to-turn outwardly about their lower endsa-sfulcra. 1

One of the objects of any invent-ion is to eliminate the use of nails and of clips secured to the molding orside of the car to hold-the outer edge of the sheet down, except; at the searns-bet-weenlthe sheets.

Anotheri'object of my invention is to pre: vent 'pucl tering of thereof sheets. Still-anotherobject of my .invention is to permit" the end portion of. the sheet to Work up and downover' a fascia having an upper rounded corner; and with these and minor objects in view, my invention consists of theparts; and combination of parts as willbe hereinafter pointed out.

'In-thedrawing, Figure-1 is a side elevation ofa car, partsbeing broken away, with my invention embodied, Fig. 2 is a section on the line 2-9, 'Fig. 1; Fig.3 is a detail sectional viewiof a carat the eaves showing a modified form-of roof clip; Fig. 4 is a perspective view of the clip shownin Fig. 3;

Fig. 5 is a'detai1-sectiona1 view of a roofing sheet having the clip secured on its under face; Fig. 6 is a: detail sectional-view of a.

sheets. down over the caves of the car and secure the bent over portion to a fascia or to the side of the car by means of nails, clips, etc, but it has been found that this results in the tearing of the sheets" at the eaves, where they are bent over, inasmuch as the tendency of the sheets to slide longitudi nally is resisted, thus permitting water, snow, dust and cinders to work up under the roofing sheets thence into, the car. I overcome these objections and the faulty constructi'on by riveting or otherwise suitably securing to the. roofing sheet 2 clips 8, conforming to the bend of the sheet at the eaves as shown in Fig. 1 One arm of the clip is secured to the main body or portion of the sheet, while the other arm is secured to--the turned down portion 9 of the sheet.

10 is a roof 'seam clip provided with a hood 11 constructed to close the open. end of the seam 12 and cover a portion of the seam as shown in Fig. 1. The apron of the seam clip is wide enough to bridge the gap between the turned down portion of the sheets at the seam and is provided with wide spreading side wings 13, which project over the down turned portion 9 of the roof sheets, as shown, thereby assisting the clips 8 in holding the roof sheets in their bent position.

The wings or arms 13 are slightly thinner Y thanfthe apron of the seam clip as shown in Fig. 7, in order that the under face of the apron may be secured snugly against the fascia or side of the car, the extra thickness of the apron serving as a spacing block for the wings 13, thus spacing tl'iem from the fascia or side of the car to permit of the portion 9 of the roofing sheets occupying 13 is inserted in. the upper opening, the

body thereof passing between the side edges of adjacent sheets and above the down turned ends of the sheets which overhang the eaves of the car, whereby the clip is secured to the car at the eaves between the down-turned ends of the sheet. The bolt,

nail or screw 13 is passed through the lower fiopies of this patent niay be obtained for be secured to the under face of the roofing sheets as shown in Fig. 5; and it may be provided with a reinforcing rib 1 1 as shown in Figs. 3 and 4. The roofing sheets may be dohbled baek at the outer end and have sheets puckering, curling up or outwardly,

and further eliminate the liability of the root sheets tearing, as happens in the constructions where'th end of the sheet is nailed or otherwise rigidly secured to the fascia or side of the ear. I Another advantage of this construction is that the end portion of the sheet is free to work up and down over the rounded corner of the fascia. T he wings 18 ot' the roof seam clip hold the downwardly bent portion 9 from bending outwardly or curling at the side edges of the,

sheet. I

The fascia 15 extends outwardly far enough beyond the cliis and roof sheets to protect them against side scraping and is of such shape that water will readily run off of it free trourthe side of the car.

IV hat I claim is 1. A car roof comprising metal sheets 'flexiblv connected by interlocking flanges extending 'from the eaves to the ridge, the outer portion of each sheet being bent down over the eaves,and means secured to each sheet in the outer bent down portion to maintain the angular relation of the bent portion relative to the main body portion of the sheet.

2. A car root comprising meta-l sheets flexibly connected by interlocking flanges -extendingfrom the caves to the ridge, the outer portion of each sheetbeing rounded and bent down over the eaves, a fascia having a rounded upper corner braces secured in the rounded and bent down. portion of the sheets to maintain the shape of this porthe outer portion OfWlllCll is bent down to form an eaves bend at right angles to the main portion of the sheet, of brackets secured in said bend to stiffen the bent port-ion and maintain the angular-relation be-- tween said bent portion and the main portion of the sheet.

4.' In a car roof comprising roof sheets movably secured thereon having downturned ends overhan ing the eaves, eaves clips arranged at the oint between adjacent) roof sheets to overlie the same, said eaves clips comprising base portions and wing portions extending from the outer edges of the base portions and overlapping the down-turned ends of adjacent roof sheets, said base portions being of greater thickness than the wing port-ions, wherebythe wing portions are spaced from the roof'sheets and loosely secure the latter at the eaves corners thereof.

5. In a car roof comprising roof sheets movably secured thereon having downturned ends overhanging the eaves, eaves clips arranged at the joints between adjacent roof sheets to overlie the same, said WALTER P. MURPHY. Witnesses:
