ROOFING FASTENER Filed July 29, 1929 ATTORNEY Patented Oct. 1932 UNITED STATES am? JESSE FULENWIDER AND HARRY FULE NWIDER, OF SAVANNAH, GEORGIA, ASSIGNORS TO THE SOUTHERN STATES IRON ROOFING COMPANY, INC., OF SAVANNAH, GEORGIA ROOFING FASTENER- I Application filed July 29,

Our present invention has reference to fastening devices for sheet metal roofing, and particularly to that type of device which is used for holding in place the ends ofgal- '5 vanized sheet roofing arranged where one or more sheets must be used from comb of the roof to the cave of theroof, and also for holding in place or locking down the ends of the sheets of roofing on the bottom course,

19 where the ends of the sheets of roofing touch the caves of the roof.

The primary object of the invention is the provision of simple means for holding the ends of the sheets in place and provide for the expansion and contraction of the metal roofing sheets and to prevent water from blowing up under the ends of the metal roofing during hard hail and wind storms.

To the attainment of the foregoing and 20 other objects which will present themselves Figure 2 is a sectional View approximately on the line 2-2 of Figure 1.

Figure 3 is a perspective view of one of the fasteners.

W hile in the drawing we have illustrated our improvement in connection with metal roofing sheets 1 provided with central longitudinally extending substantially cross sec.- tional outstanding ribs and with similar ribs adjacent to the edges thereof, obviously the device may be employed with other types of roofing sheets. As is'well known the roofing sheets are arranged over the roof sheathing so that the ends thereof are overlapped from four to 12 inches over each other. Where these laps are made the sheets of roofing do not lie smooth. They have a decided tendency for the flat part of the end of the upper sheet to pucker up and buckle which leaves a gapping space or spaces where the end laps are made. In blowing rains it is an easy matter for water. to blow up under these open spaces and cause the roof to leak. Also these gappings and buckled places are unsightly tend to spoil theentire roof. Obviously the edges of the sheets at the lapping por the distortion and buckling of the ends of f the roofing sheets, but the nailing of the edges would notcompletely close up the irfregulari- Y ties between the sheets andbesides it has been found a very bad practice -to drive nailsfl throughthe fiat parts of galvanized metal roofing sheets for'the reason that when the nails are driven through such parts of the metal the heat from the sun and the shrinkage of thesheat hing lumber underneath, almost invariably causes the nails to loosen and rise up and the openings in the sheets closed by the nails provide passages for Water which obviously causes the leaking of the roof.

In carrying out our invention we employ comparatively narrow plates 2 which, when employed in connection with the form of roof disclosed by the drawing are centrally formed with upstanding ribs 3 by grooving or corrugating the said plates. Each plate 2 is provided with openings 4: for the recep-' will be seen that the plates 2 are arranged over and secured to oneof the roofing sheets 1, at a point below the edge thereof to be lapped by'the next roofing sheet. When-the next roofing sheet is arranged over the first mentioned roofingsheet and'is received in the cleats 5 and likewise has its central rib received in the rib 3 of the said sheet 2 the cleats 5are hammered over the overlapping roofing sheet it, of course, being understood that the plate 2; is nailed .to theunderlying sheet. f

We have found, however, that a more perfect joint can be obtained by forming the plates 2 with central longitudinally extending outwardly projected cross sectionally rounded ribs 7 over which the roofing sheets The are inserted prior to the hammering of the cleats 5 thereagainst. Such hammering of the cleats 5 will cause the sheets 1 to bend against the longitudinal ribs 7 and to be tightly contacted by at least the outer faces of the ribs and thereby afford a positivelocking joint. Also we preferably adhesively or otherwise secure to the under face'ofthe' plates 2 compressible strips 6 as disclosed by the drawing.

Having described the inventiion, we claim A roofing comprising metal sheets which have their edges disposed in lapping relation, a plate arranged transversely of and adjacent to the end of each metal'sheet, nailed to the sheets and to'the roofing, the

said plate having its outer edge formed with bendable cleats designed to receive therein and to be bent over the edge of the overlapl ing plate'and to be hammeredthereagainst,

and said 'plate being centrally formed with a longitudinally extending outwardly projecting cross sectionally rounded rib for contacting engagement withand for crimping the edgeof the plate arranged thereover, and

plate having an inner compressible I said facing. V In testimony whereof we aflix' our signatures.
