Figures 7, 8 and 9 relate to embodiments of the invention adapted to permit relative movements of the roofing and of the underrooing caused by expansion and contraction due to temperature variations.

Figure 7 illustrates an embodiment of my device as adapted for securing roofing on timber-work. v

Figure 7a shows a detail thereof.

Figure 8 shows a device ,adapted for-.securing i'oong onA metal framework.

Figure 9 illustrates a device adapted for securing roofing on battens or on any plane surfaces.

Figure 10 shows, partly in section, an im! plement for positioning the fastener illustrated by Figure 11 which is the same as the one shown by Figure 7 but on an enlarged scale.

Figure 10a is 'a 1010d of'Figure 10.

Figures 12, 13 and 14 relate-to a modification applicable preferably where the overlapping of broadly corrugated plates is desired to be reduced as much as possible. The device shown by Figure 12 is suitable for timberwork,.the one shown by Figure 13 for metal framing, and the one shown by Figure lfi'comprises an articulation or link analogous to the one shown by Figures 7 cross-section on line 8 and 9 while the attachment thereof can be effected by meansA of the implement repre-l sented in Figure 10.

In all the tiguresthe same reference letters denote the same parts.

The' securing or fastening device shown by Figures l, 2, and 3, is essentially constituted.

by a, metal hook A, preferably made of iron, the top portion B of vvl'iiclilisgthreaded, While its bottom portion C is bent or curved so as to offer a shape fitting the section of the framework beams or girders D (Figures 2 and 3).

On the stem of the hook 'A is sli-dably mounted a sleeve F provided at its lower end with a sheet-,metal member E shaped to fit the corrugations of the plates K that make up the roofing. .Above sleeve F is positioned a square disk G made of malleable metal, preferably of lead, upon which is superimposed a cap topped in its turn by a washer I, preferably made of lead. A nut J screws on threads B. Optionally an iron washer may be interposed between said nut and washer I.

I usethe above described device in the following inanner:

Having laid in alinement on the framing the corrugated or smooth plates K (Figures 2 and 3)' I mark the fastening points thereon by means of a chalk line, after which I pierce lsaid plates at the proper places through the tops of the corrugations, as usual, takingcare tlat the holes be of a diameter slightlyy larger than the diameter of 'hook A inorc er to allow the roofing suficient Aplay for expansion and contraction.

I lift up the plates at vthe points wherethey overlap` and-separate the stem of each hook'A from all the above described mov' able parts. )I then introduce between the plates the sleeved separating or .partition member E-F so that the sleeve thereof will pass through the hole in the upper plate and protrude above the roofing (Figures 2 and 3).v 1I. then introduce'tlie stem of the fastening member 'into sleeve- F, while hooking, by .means of portion C, themetal beam or girder'D.. I` then put on the leaden disk G. so' that yits diagonal willbe set exiactly in thedirection ofthe roofs slope; I next position the-closing cap I-I, the bases of which, preferably4 squarel andl slightly ably be rounded or recessed so as vto prevent' the hammering from damaging thethreads. I then lay the next plate by engaging/the` ^it also'will be` in the direction of the roofs slope. I then cover cap H with leaden washer I, and, if I so desire, with a sheetmetal or an iron washer, and I clamp and lock the whole together by tightening nut J.

Of course, the fastening'device for metal framework may' be made of the type illustrated by Figure 4. In this case, the hooked rod or bolt is analogous to the aforedescribcd one and the sheet-iron plates of the roofing are joined by means of two nuts J 1-J z com'- bined with two malleable metal washers` I1 I".

,The lower nut J 2 and its washer I2 are for the purpose of preventing the pressure exerted by the upper nut J from exert-ing harmful action on the conrugations of plates K.

For securing said plates, I first tighten the upper nut J so that said plates will rest truly on4 the frame work, and, then, I tighten jam-nut or check-nut J. e I will now describe, by reference to Fig'- ures 5 and 6, a fastener adapted to secure roofing on timber-work and battens.

In this case, the fastener is formed of a metal rod A1, threaded at its top portion B1, and' comprising, fixed at X by any suitable means, a convex metal separating or spacing member El analogous tothe one shown at E in Figures 1, 2 and 3.'

The lower end of rod A1 is tapered or pointed and provided with barbs or flukes L. f A leaden washer I (and, if desired, an

iron washer) is superimposed over the sheet? iron member E1 and a-nut J2' is screwedon the 'threadedportion B1.l Y'

This device is used as follows:

Having properly laid thesheetiron plates and completed their perforation, as hereinbefore explained, I' form holes in the rafters or such like so as to facilitate the vdriving in of rods A1. I then push back the first row of plates one plates width, and I secure the rst plate by means of rod A1,`prceed ing in such a way that member E1L will rest truly on the corrugationjofsaid plate. Head M of the fastening rod Vshould'preferlatters holes on the threaded portions of .v vthe cfastenings. I position the leaden washer I, and if any, the aforementioned iron washer, and I clamp the whole together by means of nut'J. l

Of course, the devices just described can be 'applied in the same way as above foi' securing smooth plates, but, in the latter case. thel members E-E1 should be flat in- `stead of convex.

The above described devices offer numerous advantages, to wlt:

In the -case of corrugated iron sheets or' plates the latters corrugations are reinforced at-the fastening points by the convex separating .member positioned between the plates so that the pressure of the nut can no longer have thel least detrimental iniuence. 1vVater, meeting' 4first of all the part of the cap which is lined with lead or other malleable metal, gets, therefore, but very little hold, and is divided by the cap and is immediately led into the troughs of the corrugations. If, however, water eventually manages to find its way under the base ofthe closing cap land of. theleaden disk, it would meet the convex separating member E and its sleeve F, which projects through'the roofing plates-'into the closing cap. Such water would then jagainbe led into vthe troughs of the corrugations and would drip on the `corrugated plate'next Since the convex separating members reinforce the plates, my. invention offers a better foothold 'on corrugated rooiigs, es-

peciallyif care is taken to walk as nearly as poss1ble along the lines of fastening points. Furthermore, the lf'aste1 1i11g:, devices protrude a good deal, thereby permitting rooflayers to use them as supports for any scafoldmgs, ladders, etc., .whereby the handling of roofingplates is greatly facilitated. In the .case of roofing to- 'be secured on timber-work or battens l the same advantages obtain as to watertightness,'with this difference,'howe ver, that any .wateifinding its way under the top washer irojllld'- meetr the member E1 which is fast on threaded rod A1. Q' l The fasteningrods are provided with barbs which hold them rmlly .'in'thetim'ber orA wood and they cannot fshakef themselves loose since they have to carry the-."weightof the roofing and are thereby kept secure. Indeed, even if they actually become loose, a practical impossibility, .no infiltration o'f water could occur'since "there: would a1- ways. remain: the separating member bolted los vIt should benoted-thfa cases, the 'i separating members, can be made more orvv less long. The Alonger'they are the more the roofing willv-'bereinforced and the 'better supported; so that it will become 1.20` orplates apply alsogto smooth metal sheets Another characteristic of said device relates to the peculiarrand special construction of the member that serves to lock the coniponenty parts of the device on the overlapping surfaces.

' The device shown by Figure 7 comprises a nietal rod A4, having top portion B threaded and its lower portion linked to a tapered rod A5 provided, for instance, at its free `end with barbs L.

be effected by means of,

The linking can n A3 or'by any other suitsay, two eyelets A2, able means. made disconnectible.

- Said articulated rod is combined with: a separating'member or partition E fitted at its upper portion with; a square disk G of malleable metal; a suitably shaped iron cap H; a cover Z, made of cast iron or of any other metal and formed internally with a depending hemispherical portion Y provided with a threaded hole X1. Said piece Z is locked'by means of a check nut or jam nut W screwed on the end of rod A4k which terminates in a point. A wedge Z1 (Fig. 7a) ma be provided and may be driven through a s ot B1 in the threaded-,part B ofsaid rod to prevent any loosening of the check nut.

'Ihe device illustrated by Figure Sis intended for securing roofings on metal beams fastening device of Figure or girders. It only differs from thatshown by Figure 7 by the` feature that rod A4 is provided with ahook A6 which is shaped to fit the section of the metal beam.

The device illustrated by Figure 9 is designed for the purpose on battens or plane surfaces and comprises at its lower parta small plate P wherein is an eye A".

Figure or implement the articulated 7, represented on an enlarged scale at Figure 11.

Said tool is composed of a metal tube T permitting rod A4 to be passed' through.

10 shows a tool which 'is used in applying l, The upper portion of this tube may be fitted v on the free end of rod inside with a wooden sheath Q, intended to.

protect the threading 4B of rod Af. In its lower portion, tube. T has suitably formed and sized recesses t0 permit the sliding of eyes A2 and A3.

The overlapping plates K are y laid on one another, as sho)wn by Figure 7 and are formed with holes at suitable places. Through these holes I run the tool ory implement above described, said tool holding the fastening member. I rest the lower end of tube T on the frame work and I strike blows until it is entirely As already stated,l it can beof securing roofing f rious elementsconstituting the fastening device in the same manner as afore explained.

'Ilie modification shown by .Figure 12 is adapted for timber-work. It permits, as h ereinbefore stated, to spare as much as possible the overlapping of broad-corrugated plates. This device is constituted by a rod A8, threaded at its top portion B, which is tapered andy terminates at its bottom in barbs L. In the case of metal girdersasaid barbs may be replaced by la hook A9 shaped to fit the girder section.

Said rod mayv` also have an articulation of any kind, as in the case of 4Figures 7, 8, 10 and 11. In all cases it'is combined with a socket or sleeve F2 providedl with an oval base-E2 shaped to conform to the section of the corrugation. The outside of said sleeve is threaded. A washer G2, made of lead or other malleable metal, an iron washer H2 and an outer socket or.,sleeve I2 complete the device. The lower part of socket I2 has itsinside threaded so as to screw on sleeve F2, and its upper part, also threaded on the inside,is adapted to be screwed on rod A8.

Said socket I2 a suitable spaniier. with four or six faces so as to be operated like an ordinary square oi` hexagonal nut.

For laying the roofing-.plates I proceed as follows: j

I perforate said plates at the required places. I then introducel sleeve F2 into a hole so made. I screw o n .the sleeve the leadeii washer G2 so that the sleeve will be properly held in the plate. I

It should be knoted that when laying roof-y ing plates on a'metal framing the fastening rods should be introduced from below.

If articulated rods are used for laying roofing on timber-work, they should, ofA course, be first secured on the rafters by means of the contrivance shown by Figure 10.

The above .described device will .do away with all danger of injury to the plate corcan be put on by means of Its outside may be made rugations either from the pressure ofthe clamping 'nut or from careless or excessive driving in of nails or fastening screws. vBy being screwed on the thread of rod Aa the Vfixing socket I2 engages the threads on sleeve F2'and, by'bearing on iron washer H2, draws support for the plate,

face of said washer.

prevent any infiltration of water that might oc'cur in case rod As should become loosened from the under-roofing, since the joint of the fastening point of the plate must al-v ways remain gripped between socket I2 and sleeve F2' which Aare screwed into one another. Y

Obviously, the latter device can be used not only for broad corrugated but also for ordinary corrugated iron roofing.

Having now particularly ascertained and described the nature of my said invention as well as the manner in which the same is to be performed I declare that what I claim is:
