, Application filed May 10, 1915. Serial No. 27,244.

To ZZ whom it may concern Y Be it known that L CooPER S. HAMMOND, a citizen of the United States, residing at thecity of St. Louis andState ofMissouri,

have invented a new'and useful Roof, ofl

which the following is a specification. v

This invention relates to metallic roofing.'V An object of the invention is to provide an improved sheet-metal roof composedfof sections of sheet metal secured t' f the supporting roof structure bynails'or other fastening devices which are completely covered by overlapping portions .of the sections of sheet metal whereby corrosion of the fastening devices is prevented, a trough for-medy in the inner overlappedv portions of the sheetmetal sections for receiving and 'discharging the water which may pass underl the edges of4 the superimposed sections, thus preventing the-Water from reaching the fas! g tening devices or the Supporting portions of the roof, and improved fastening or .clamp-- Ving elements by which the overlapped-por# tions of the sheet metal are secured together without the necessity of Securing said lastsupporting named fastening devices to the portions of the roof.,

Another object is to provide an in uprovedv sheet metal roof comprising sectionsofsheet Ametal provided with raised overlapping portions with fastening devices for the under sections entering the roof vsupport and.

Wholly covered by the upper sections, non? corrosive fastening devices binding together.

the raised overlapping portions of the sheet' v metal'sections without engagement with the roof supporting structure, and troughs.- -formed in the underoverlapping portions.vv for receiving and discharging whatever moisture may 'pass between said. sections,

thus preventing the moisture from reaching the roof supporting structure orthefastene Aing devicesbinding the roofing thereon.;-

Another object is to provide an improve non-corrosive fastening device forfastenin together `the overlapping' portions of th porting structure. There are other objects and (advantages and which do not require lspecific mention Patented Apr. 1s, 191e. L .1

The oppositeedgs of each Y nabled to bear against theroof support and section of sheet metal is formed with a raised portion consisting of the two obliquely disposed walls 9 connected by a flat portion 10. ThusV a channel is forinedwhicli is 'adapted to receive the raised portion of an adjacent sheet metal section including the walls 2 and 2 and the trough or channel 3 formed therebetween.

In constructing the roof the sections 1 of the sheet metal are placed upon the supporting structure 6 and the lateral extensions at are secured to the roof by the nails 5 passing through vholes in said extensions and being driven `into the roof support. Duplicate sections are then placed inposi'- 'tion with the raised portions consisting of the'walls 2 and Q and the channel 3 of the first-laid sections received within the overlapping portions 9-10 of the super-imposed sections. Thus, the trough or channel of tlie'under sections are covered by the overlapping of the adjacentsections which bear against the flat surfaces of the fiat portions 7 and 8, and thus form close joints to prevent thevmoisture from passing farther between the overlapping portions of the sheetinetal. The nails 5 aregeiiipletely.covered-by the sheet metal, and itispraetically impossible for the moisture to reach the nails, so that they do not deteriorate by corrosion,fas occurs in rooting of ordinary construction, or of any construction in which the nails are exposedand are accessible to the moisture. j

For the purpose of securing together the overlapping:portions of the lateral adjacent sections I vhave provided fastening devices of novel construction. The Vclamp `Which I have devised, 'and which is adjustableA in; connection with the overlapping portions of the sheet metal sections effectively fto bind and secure them together withoutl engaging the roof supporting structure or sheathing, comprises a central head portion 11 provided with a. `flange 12 around its lower edge, and with integral extensions or -arins 13. The arms 13 are extended through holes in the overlapping portions of the sheet metal sections and are clamped against the inner surfaces of the subjaeent sections, thus securing the parts together. As. illustrated the clamp device is applied /to the overlapping raised portions by pressing the arms 13 through holes in the part 10 of the outer` section and through holes in the lat portion 8 of the'lower section. Thus thefastening devices kare supported. above the plane of the inain portion Vof the roofing so" that water isnot enabled to pass through the holes through which the fastening'elements extend. The arms 13 may be passed through the holes as the different sections of sheet metal are placed, and said larms may be spreadapart and clamped by any suitableV or known y'device applicable to suchy purpose. In connection with this clamping device I provide a non-corrosive protector or shield.' The head 11 is pi'ovided with an extended portion 16 adaptedk to be. folded upon the upper surface ofthel head, thus completely covering the central part of the fasteningdevice. The head 11 f is provided with a--hole 1T through which the tool may be passed for spreading and clamping the arms 13 as above explained. After the clamp has been securedin position the extended portion 16.' constituting a protecting shield is folded upon the head or body 11 of the clamp. thus closing the hole 17 and also protecting the outer lsurface of the clamp'.` n 7 j f In Figs. G to S) I have illustrated another form of clampv for securing together `the overlapping portionsof the sheet metal sections. "This alternative vform of clamp comprises a central head portion 111dk provided with integral extensions which may be folded against the central portion asindicated `at 12 in Fig.A '7 and bent to provide laterally extending portions or arins12 projected at right-angles from the central head portion 1l, This fornrof the clampA is secured to the overlapping portions of ythe sheet metal sections by passing the arms 13 i through holes in the sections and clamping the arms against the inner surfaces of the subjaeent sections, thus clamping the parts together. In connection with vthis clamping device I provide a separable non-'corrosive protector or shield ywhich consists of a flexible platellf, composed of lead ory other suitable non-corrosive material and having a hole 15n through which the arms 13ar are passed, so "that the plate is interposed be tween the head portion 11 lof the clamp device and the roofing. The plate lJfis provided with an extended portion 16a adapted f to be folded upon the upper surface of the head 11, thus covering the head of the clamp, and preventing it from deterioration by corrosion. The head 11u is provided with a hole 17 through which the clamping-tool may be passed for spreading and clamping the arms 13a inthe sainemanner that Jthe arms 13 of the previously described clamp are spread and clamped. After the clamp has been secured in position the extended v portion 1G, constituting a protecting shield,

is folded upon the head or body lla'of the clamp, thus closing lthe hole 17a` and also protecting the surface ofthe clamp.

The upper end of e'ach'of the sheet metal sections is folded to provide a transverse engaging portion 18'between the overlapf ping portions at Vthe sides of the section adapted to engageV` with' an under folded portion 19 formedat the lower end of the upwardly adjacent section. I prefer to form the folded extensions 19 somewhat longer than the extensions 18 in order to afford sufficient material and vspace for slight variiso ation in adjusting and placing the rooting sections.

lt will be understood that there may be variations in the construction and. arrangement of the part of the invention without departing from the principles thereof. I do not restrict myself to exact features of con struction, but

lVhat I claim and desire to secure by Letters Patent of the United States is:
