1 Claim. (Cl. 189-86) My invention relates to panels for use in the building art.

Many types of bungalows and other dwellings have their outer walls finished with clapboard or feather edge which gives a pleasing appearance to the exterior of the building; However this type of outer wall, when constructed of wood, has its disadvantages, in that unless it is painted every few years, it soon begins to look shabby and the old paint weathers and scales off exposing the wood work to the vicissitudes of the elements, and deterioration or rot sets in.

The use of dressed wood is in the first instance, costly, and when it is considered that the lifetime of timber is relatively short being exposed to termites and other pests and the cost of periodic painting and labour involved is high, it was apparent to me that other and more permanent types of finishing could be used, which would have long life and durability and possess all the aesthetic features of known sidings and finishings.

Consequently I have come to the conclusion that metallic siding or an equivalent, such as Fiberglas or other synthetic materials, would lend itself to building construction, and to this end I have invented a metallic or equivalent panelling which may be used to constitute the outer Walls of a building and to give a useful and attractive finish thereto.

The panelling which I have invented is so constructed that insulating material can be positioned in the interior of the panel, so assuring a suitable temperature in a building all the year round.

Moreover the type of panel which I have invented can be used as an acoustical ceiling by merely providing a plurality of apertures in the outer wall of the panel and placing in the interior of the panel a pad of mineral wool or other acoustical material.

.The advantages of the use of metallic or equivalent panelling in building construction is obvious, and what I am particularly interested in is to construct the panels so that the abutting end walls. of the panels may be.

securely joined and locked in position.

One of the objects of my invention is to provide a building panel which while strong and durable, may be fabricated with pleasing lines, so adding to the aesthetic beauty of a building finished with such panels.

Another object is to retain the assembled panels in- Other objects will be made clear as the specification I develops.

So that the nature of my invention will be clearly understood, I have illustrated two embodiments of the same'which I shall describe in detail, but I wish it to be understood that I do not limit my invention to these specific forms, but reserve the right to modify the same within the scope of my appended claim.

Like characters of reference refer to like parts in the several figures.

Referring to Figures 1 to 8 inclusive of the drawings, A represents a part of a panel blank, the upper and lower ends of which are identical, so that the shape of one end will be described in detail, but the reference characters Will be applied to both ends wherever possible.

The length of the panels will be such as are required for the desired purpose, and the panels will be cut from strips of aluminium or other suitable material of the desired Width so that there will be a minimum of wastage in the cutting operations.

The end of each panel blank A is formed at its upper and lower edge with a rectangular projecting portion 10, the outer marginal portions of which are provided with orifices 11. The dotted lines 7 and 8 shown on the projecting rectangular portion 10 are for a purpose which will be referred to hereafter.

By reference to Figure 2 it will be seen that the left hand marginal portion 12 is cut away and angularly disposed as shown at 13 towards the rectangular projection 10, and that the part of this marginal portion adjacent the projecting rectangular portion 10 is provided with a 0 slit or cut 14 which extends to the root of the rectangular projection 10.

This marginal portion 12 of the blank A is shown,

with two dotted lines, 15 and 9, on which the marginal portion is partially folded to form a V-shaped flange 16 which constitutes a male member B of an interlocking joint between adjacent panels A.

The opposite or right hand marginal portion 17 of the panel blank A is formed with a portion of its upper edge 18 angularly disposed towards the rectangular portion 16, and is formed with a slit or cut 19 which extends to the root of the rectangular projection 10, the slit 19 being .of the same depth as the slit 14 on the left hand portion of the panel. From the lower outer end of the angular edge 18 an upper edge 20 of the marginal portion 17 extends outwardly at right angles to the vertical edge of the panel blank A, and adjacent the marginal portion of the blank a plurality of orifices 21 are provided.

The right hand marginal portion 17 of the panel A is shown with five dotted lines 22, 23, 24, 25 and 25a, and along these lines the right hand marginal portion 17 is folded to form a double bend which simulates the letter N, and constitutes a female member C of the interlocking joint between adjacent panels.

As previously stated the lower end of the panel blank A is similar in all respects to the upper end which is described in detail above.

When the rectangular blank, which for the purposes of description is formed of an aluminum sheet, is cut away or shaped as above described, then the marginal portion 12 on the left hand side of the blank is partially folded on the'line 9, and a further folding operation is performed in the opposite direction on the line 15, so forming a V-shaped locking portion =16 of the male joint B, and the V-shaped portion extends from the top to the bottom of the panel blank A.

That part of the upper edge 13 of the marginal portion 12 which is provided with the slit 14 now underlies the plane of the blank A and is folded inwardly beneath the blank to form a lug 26 as shown in Figure 3. The right hand marginal portion 17 of the panel blank A is now folded downwardly on the line 22 and a second folding operation is made on the dotted line 24 as clearly shown in Figure 6.

A third folding is made along the line 23 so that this fold underlies the lateral end wall of the panel A, whereupon a fourth folding operation is made on the line 25 to form the female part C of the joint and the marginal portion on the right hand of the panel blank A projects outwardly forming a lateral flange 27, which is broken upwardly on the line 25a to form the inclined side wall 27a of a water trough.

The portion bounded by the slit 19 and the inclined edge 18 of the marginal portion 17 underlies the plane of the plane blank A, and is folded inwardly thereunder to form a lug 28 as shown in Figure 3.

The rectangular upper and lower portions of the panel blank A are folded downwardly on the dotted line 8 at right angles to the plane of the panel blank, and the outer margin of the rectangular projecting portion 10 is then folded outwardly on the dotted line '7 to form a flange 6 as shown in Figure 1. It will be clear that lugs 26 and 28 bridge the spaces between the lateral walls of the panel and the upper and lower end walls of the panel.

This folding of the marginal portions of the panel blank A forms a panel, the under or inner side of which is dished, and adapted to receive and retain therein, a pad of rock wool or other suitable insulating material. The flanges 27 and 6 lie in the same plane which is parallel to the outer face of the panel A.

A plurality of these panels may be used to complete or finish the outer walls of a dwelling or other building, and one panel is secured to the outer rough lumber siding of the building by nails which are driven through the orifices 11 and 21 into the woodwork.

The next panel is now positioned adjacent to the first fixed panel and inclined outwardly at an angle thereto so that the lip of the V-shaped groove 16 of the male 4 I portion B of the joint is inserted between the flange 27 and the folded female portion of the joint C.

The second panel is now rotated towards the Wall of the building on which the panels are being mounted, and this causes the male portion B of the joint to engage the groove of the female portion C of the joint, and the second panel is now in alignment with the first panel and is locked end to end in alignment therewith, whereupon the second panel is secured to the woodwork of the frame of the building by nails.

The assembly of the adjacent parts of the panels will be understood by reference to Figure 4 and it will be clear that the interlocking of adjacent panels is positive so that displacement of the panels is not possible and the panels are held in alignment. This operation is repeated with the assembly of each row of panels until the outer walls of the building are covered.

In the event of unexpected leakage of water taking place between the male and female portions B and C of the joint, such water would be caught in the trough formed by the flange 27 and the broken up inclined edge 27a, and the water drained oif.

Referring now to Figure 9, the upper portion of a panel blank A1 is illustrated, but it will be understood that the lower edge portion of the blank is of similar construction but oppositely disposed to the upper portion, and it is not thought necessary to illustrate the panel blank in full.

In Figures 9 to 12 the panel blank A1 is formed on its upper edge and similarly on its lower edge with a projecting rectangular portion 30, and the left hand marginal portion 31 of the blank has its upper and lower edges angularly disposed relatively to the adjacent lateral edge of the rectangular portion 30 as shown at 32.

A dotted line 33 is shown on the panel blank A1 in Figure 9 and the marginal portion 31 of the panel blank is partially folded on this line downwardly and angularly relatively to the face of the panel blank, and this folded portion 31 underlies the panel blank and constitutes the male member D of a joint between adjacent panels as shown in Figure 11.

The marginal portion 34 on the right hand side of the panel blank A1 is formed with upper and lower edges extending from the root of the rectangular projection 30 and at right angles to the lateral edge of the rectangular projection, and the edges 35 are each provided intermediate of their length with a V-shaped notch 36.

Dotted lines 37, 38, 39 and 40 are shown on the face of the panel blank A1, and the line 37 extends between the right hand lateral edge of the upper rectangular projection 30 to the right hand lateral edge on the corresponding projection on the lower end of the panel blank. The lines 38, 39 and 40 extend between the ends and center of the V-shaped notch 36 on the upper edge 35 to the corresponding V-shaped notch on the edge at the lower end of the panel blank.

The right hand marginal portion 34 of the panel blank A1 is now folded along the lines 37, 38, 39 and 40 to form a female member E and a projecting flange 41 of a joint between adjacent panels as shown in Figure 11.

The folds formed along the lines 37, .38 and 39 constitute a double fold, and simulate a letter N reversed, and the extreme marginal portion between the line 40 and the lateral edge of the panel blank A1 constitute the flange 41 which is provided with orifices 42.

The rectangular projecting portions 30 on the upper and lower ends of the panel blank A1 have two dotted lines 43 and 44, and the projecting portion 30 is folded downwardly at right angles to the plane of the outer face of the panel blank A1 along the line 43, and a second fold is made along the line 44 at right angles to the first fold, to constitute a flange 45 which is provided with orifices 46. The flanges 41 and .5 lie in the same plane which is parallel with the upper face of the panel blank In assembling these panels on the outer walls of a building, one of the panels A1 is located in the desired position, and nails are driven through the orifices 46 and 42 in the flanges 45 and 41 into the wooden siding of the building firmly securing this first panel in position.

-A second panel A1 is then positioned as shown in Figure 11, slightly spaced from the first panel A1, with the male member D in alignment with the female member E of the panel joint, and the second panel is pressed towards the wooden siding of the building so that the male member frictionally engages with, and is embraced by the female member E of the joint. In this position the flanges 45 and 41 of the second panel A1 engage the outer face of the wooden siding of the building to which the second panel A1 is secured by nails driven through the orifices 46 and 42 of the flanges 45 and 41 into the wooden siding. The two assembled panels are shown in Figure 12.

The above operation is repeated with other panels until the outer wall of the building is completely covered by the panels.

Insulating material in the desired form, such as pads, may be readily placed in the interior of each panel before assembly.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

I claim:

A rectangular building panel having upper and lower depending end walls, flanges extending outwardly from the lower edges of the end walls, a downwardly and outwardly inclined side wall having an upwardly and outwardly inclined portion forming the male member of a joint, a second side wall inclined downwardly and outwardly from the panel and reversely bent inwardly and upwardly and then downwardly to form a double fold with the folds in an inclined plane and spread apart constituting the female member of. the joint, the lower end of the second side wall terminating below the folds in an outwardly extending flange having its outer edge turned upwardly to form a trough.
