Specification of Letters latent.
Patented Aug.. 13, 1918.
To all 'whom t may concern:
Be it known that I, WALTER P. MURPHY, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.
In car roofs of the so-called outside metal type, there are metal roof sheets which rest upon a wooden sheathing. The roof boards constituting this sheathing are usually nailed to wooden purlins; and there is a tendency, due to the racking, and weaving of the car in service, for the nails to work upwardly and eventually work their way through the metal roof sheets. The purpose of the present invention is to protect the metal sheets against this action.
In the accompanying drawing, which forms a part of this specification, and wherein like symbols refer to like parts wherever they occur, i
Figure 1 is a plan view of a portion of an outside metal roof, with the metal sheets removed;
Fig. 2 is a crosssection on the line 2-2 of Fig. l, with the metal roof sheets in position;
Fig. 3 is an enlarged detail cross-sectional view through one of the purlins in the same plane as Fig. 2; and
Fig. l is a detail sectional view on the line 4-4 of Fig. 3.
The' construction illustrated in the accompanying drawing comprises a side plate l of the car, side sheathing 2, fascia 3, and metal carlines l, all of well-known construction and arrangement. The carlines l extend crosswise of the car from side plate to side plate and are provided with seats for purlins 5 and ridge pole 6 which extend longitudinally of the car and are secured thereto. The wooden sheathing or roof boards 7 are supported by and secured to the side plates, purlins and ridge pole. For this purpose, nails 8 are used. The nails which secure the roof boards to the purlins are long enough to project some distance through the purlins, and the projecting ends Copies of this patent may be obtained for the ridge pole is shallow enough, it is de-v sirable touse long enough nails at the ridge to admit of their being clenched also.
Located on top of the wooden sheathing ink position to cover the nails are metal strips 9. The metal strips 9 above the purlins and ridge pole are preferably secured in place by means of the bolts 10 which serve to secure the purlins and ridge pole to the carlines. At the eaves end of the car, the nails that secure the roof boards to the side plates are also covered with metal strips which are preferably formed into flashings or retainers 11 for weather-proofing and holding the eaves ends of the roof sheets 12.
By the arrangement described, the tendency for the nails to work up is overcome or checked; and even if the nails should work loose, the cover strips keep them from rubbing the metal sheets; so that instead of the rubbing being concentrated on very small areas, it is practically dissipated over the whole area of the cover strip.
What I claim is:
1. In an outside metal roof comprising wooden sheathing nailed to the substructure, metal roof sheets above said sheathing,v and cover strips located between the metal roof sheets and the wooden sheathing in position to cover the securing nails.
2. In an outside metal roof comprising wooden sheathing nailed to the substructure, metal roof sheets above said sheathing, and strips of metal located between the metal lroof sheets and the wooden sheathing in position to cover the securing nails.
3. In an outside metal roof comprising carlines, purlins and wooden sheathing nailed to the purlins and metal roof sheets, strips of metal interposed between the metal sheets and the wooden sheathing in position to cover the nails, and bolts extending through said strips, sheathing, purlins and carlines.`
Signed at Chicago, Ill., this 25th day of September, 1917.
