, r l This invention appertains to novel and useful improvements in devices for fastening sheet metal sections to a building or providing a roof thereon.

An object of this invention is to efficaciously clamp roof sections on a building structure in such a manner as to substantially obviate the sections becoming loose due to rain, wind and e the like.

Another object of this invention is to provide means for carrying out the above mentioned function.

Another purpose of this invention is to provide improved clamping means engageable with the flanges of sheet roofing which project to the interior of a building.

Another purpose of this invention is to provide a device of the nature to be described which is extremely simple, inexpensive and easily manufactured.

'Other objects and features of novelty will become apparent to those skilled in the art, in

"following the description of the illustrated pre- 'ferred embodiment of the present invention, illustrated in the accompanying drawings, wherein:

Figure 1 is a fragmentary perspective view of a roof utilizing the present invention;

' Figure 2 is a perspective view of the roof and building framing utilized beneath the roofing disclosed in Figure 1;

Figure 8 illustrates another use of the present invention;

2 Claims. (Cl. 10813) device for the purpose of eflicaciously scaling a barn, animal house, etc. from the weather. Heretofore metallic roof tops were applied to such structures by means of nails, driving the nails directly through the exposed surface of the roof sections and into the Wood structural members. The necessary consequence followed; wind entered the building and gradually lifted the roof a small amount until the roof sections rattled 10 and even blew off in times of storms.

It is well known that after a short time, the

roof sections which are secured to abuilding structure through the utility of nails, become loose to such an extent as to permit water to seep around the nails and undesirably enter the building structure.

Noting Figure 1 it is seen that no nails'are required in the attachment of.the sections to a building structure. More important, there are no nails extending through the upper surface of the roof sections whereby rain water and the like may penetrate the roof. It will be seen further that fastening means project from the upper surfaces of each roof section, to a point below predetermined structural members for anchoring purposes.

A building structure I0 is provided with a plurality of purlins l2 and M respectively which are secured to the truss members It and I8 respectively by any suitable conventional means. The

said strips l2 and M are spaced a fixed predetermined distance across for a purpose to be described hereinafter.

Sheets of metallic roofing 20 are provided with a flange 22 having a doubled back portion 24 operatively associated therewith. A

Of course, sheets of roofing material 20 are placed in side by side relation and a housing 26 is attached to a single sheet and the next adja- 40 cent sheet. The said housing is preferablysomewhat elliptical in cross sectional appearance and has a flange 28 on each inner portion thereof. The said flanges 28 are positioned in the above described flange 22 and the utility of the turned down portion 24 is now apparent.

It is to be noted at this point that there is disclosed a roof utilizing sheets of material having the general wavey configuration. However, this invention may be utilized in conjunction with many types of sheet roofing with equal effectiveness. The said housing 26 has bowed portions 30 therein which may serve the purpose of a I resilient clip when fixed to sheets of roof material. .The said housing 26 may be placed in. progressive rotation relative to each other for effecting greater length., A terminal portion of the housing 26 is undercut a, smallv amount, .re-

moving a portion of the bowed portion 30 and the flanges 22. The resulting tongue 3| on the upper part of the housing 26 then becomes somewhat resilient due to the inherent properties of the metal. The next adjacent housing may then be simply slipped under the tongue 3| as shown in Figure 10. This forms a'lap joint substantially weather resistant connection.

A specially designed clip is used in attaching the sheets of roofing to the building structure seen in Figure 2. A plate 32 having

slots

34 and 36 therein is provided with an externally threaded shank 38. An aperture is provided in the said shank 38 and a wing nut 40 with an associated washer 42 is adapted to be positioned on the said externally threaded shank. 'As is readily ap parent from an inspection of Figure 9 the plate- 32 is inserted between the purlins I2 and I4,

,.-thence-between the space. remaining between the adjacent roof sections 20. The slotsfi34 and.36

are engaged by the. flanges 22 of the said roof "of roofing having upwardly extending downtightening the said wing nut the roof may ef- .flcaciously be pulled toward the purlins thereby tightly locking the roof to the building structure. Of course, the aperture mentioned above may be utilized for the purpose of locking thewing nut -in place or may serve a second purpose to bedescribed subsequently.

-Go ing.now to Figure 4 there is disclosed an- }other embodiment of this invention, the dis- -tinguishing feature being only in the application,

of a clip 44 on the shank. Theaforementioned aperture is obviated in this embodiment. As is the like. An aperture is supplied in the clips and .the shank extends therethrough. -Of course, a

nut and associated washer may be used to hold the clip in place.

Noting now Figure 3 it is readily apparent that a slightly modified device is utilized in securing the terminal portions of the roof sections at the apex of the said roof structure 10. strip 48 is supplied adjacent th apex of the said A bracing building structure I 0. The plate 50 of. the'said fastening means is somewhat similar to the-plate '32described above. The slots 52 therein are supplied at an angle relative to the shank 54 of the :fastening means, as opposed to a substantially

parallel slot

34 and 36. Suitable securing means such as a nut 56 and an associated washer is supplied on the said shank. v Reference is now made to Figure 11 wherein there is disclosed the use of a modified form of "the crown securing means. In place of the bracing strip 48 there. is used a metallic anchor member 51 having properly inclined faces for firm seating and securing purposes.

It will be noted that the housing or crown portion 58 supplied on the said roofing sheets 20 is somewhat different from that housing utilized along the longitudinal axes of the said'plane of I the roof. The diiierence is quite evident in that the flanges are lacking. Going now to an embodiment of the invention disclosed in Figure 6, it will be noted that the plate 32 is supplied with the shank 38 accompanied by the aperture BIlmentioned :in conjunction with the embodiment of the invention '01 the invention.

4 shown in Figure 9. This aperture may be utilized for extending a cotter pin or the like therethrough or if desired, may be utilized for receiving a nail 62 extending therethrough. For this construction reference is made primarily to Figure 8.

While there has been described and illustrated but preferred embodiments of the present invention, it is apparent that variations may be made herein without departing from the spirit Accordingly, limitation is sought only in accordance with the scope of the following claims.

Having described the invention, what is claimed asnewis:

1. In a roof construction which includes sheets said sheets the improvement which comprises;
