3 Claims. (Cl. 50-238) This invention relates to siding and rooing materials andpertains particularly to building boards covered with metal or other sheet material.

One object of the present invention Iis to provide new and improved building boards covered with metal or the like and having anges or lips, made o f the covering material, and arranged along edges of the board to close the joints between adjacent boards against the entry of wind, rain and the like.

A further object is to provide a new and improved covered building board of the foregoing character which is wellradapted for use as permanent siding or roofing.

Another object is to provide such new and improved covered boards in which at least some of the lips interlock with grooves formed in edges of the boards.

Another object is to provide the overlapping lower edge of the building board with a concealed and interlocked holding device in the upper part of the underlying board.

Another object is to permit concealed nailing of the underlying board and holding the lower part of the overlying board in place with a concealed and interlocked holding device.

Still another object is to provide such new and improved covered building boards which are low in cost and extremely easy to apply.

Further objects and advantages of the present invention will appear from the following description, taken with the accompanying drawings, in which:

Fig. l is a front elevational view of a covered building board to be described as an illustrative embodiment of the present invention.

Fig. 2 is a vertical section, taken generally along a line 2-2 in Fig. 1.

Fig. 3 is a horizontal section, taken generally along a line 3-3 in Fig. l.

Fig. 4 is a fragmentary horizontal section, somewhat similar to Fig. 3, but showing a vertical joint between two adjacent boards.

Fig. 5 is a fragmentary vertical section somewhat similar to Fig. 2, but showing a horizontal joint between two adjacent boards. y

Fig. 6 is a view similar to Fig. 5, but showing Ia modied construction.

As already indicated, Figs. 1-5 illustrate a siding or roofing board 10 which comprises a relatively thick sheet of building board 12 having its front surface substantially covered with a relatively thin covering sheet 14. Preferably, the sheet 14 is made of metal, but it may be made of plastics or other suitable materials. When made of metal, the sheet 14 is preferably made of a metal which is corrosion-resistant, such as aluminum, for example. For the sake of appearance, it is preferred that the metal cover sheet 14 be suitably coated, as with baked enamel, or the like.

A wide variety of materials may be employed for the building board 12 which serves as the base of the siding or rooting material 10. Any of the common or suitable 2,961,804 Patented Nov. 29, 1960 building boards may be employed. Thus, it is merely by way of example that the board 12 is illustrated as being made of insulating berboard, which may be coated or impregnated with a waterproofing material, such as asphalt.

The base board 12 is illustrated as being generally rectangular in shape, for convenient application as siding or roofing. Thus, the board 12 has upper and

lower side edges

16 and 18, and left and

right end edges

20 and 22. In this case, the

side edges

16 and 18 are longer than the

end edges

20 and 22 but, of course, this is a matter of convenience.

Along the upper and

lower side edges

16 and 18, the board 12 has half-

lap anges

24 and 26 which project upwardly and downwardly and extend for substantially the full length of the board. In this case, both half-

lap flanges

24 and 26 are at the front of the board 12. Grooves or

channels

28 and 30 are formed in the upper and

lower side edges

16 and 18, behind the half-

lap flanges

24 and 26.

Along the

end edges

20 and 22, the board 12 also has half-

lap anges

32 and 34. In this case, however, the half-lap flange 32 is at the rear of the board 12 while the flange 34 is at the front.

For a purpose to be described shortly, the

end edges

20 and 22 are formed with rearwardly facing bevels or chamfers 36 and 38. The bevel 36 is in front of the rear half-lap flange 32 and is formed as the front wall of a V-shaped groove 40 in the left hand edge 20. It will be seen that the right hand bevel 38 runs along the rear outer corner of the front half-lap ilange 34.

From Fig. 5 it will be seen that the lower half-lap llange 26 on each board is adapted to overlap the upper half-lap ange 24 on the board below, when the boards are applied as siding or rooting. This manner of application slants the boards slightly, as seen in vertical section, so asrto promote the shedding of rain and moisture.

As indicated in Fig. 4, the front half-lap flange 34 on each board is adapted to overlap the rear ange 32 on the adjacent board, Thus, at the vertical joints, the boards are substantially flush with each other.

As shown in Fig. 2, the cover sheet 14 has rearwardly folded portions 42 and 44 along the upper and

lower edges

16 and 18. These portions 42 and 44 are folded back around the half-

lap llanges

24 and 26, to assist in securing the cover sheet 14 to the board 12. It will be understood that asphalt or other cement may be applied between the cover sheet 14 and the front surface of the board 12 to make a firm, smooth bond.

The rearwardly folded portions 42 and 44 provide laterally projecting

lips

46 and 48, which are adapted to be received in the

grooves

28 or 30 in the adjacent boards, as shown to best advantage in Fig. 5. The interlocking engagement between the lips 46 and'48 and the

grooves

28 and 30 seals out wind and moisture to a large extent, and helps to hold the horizontal edges of adjacent boards together.

In the form shown in Figs. l-S, the lips 46 and 4S take the form of double-folded portions of the cover sheet 14, extending Ylaterally as flanges which are tlush with the front of the cover sheet. Thus, each

doublefolded lip

46 or 48 has a front portion 50 which is a continuation of the cover sheet 14, and a rear portion 52 which joins with the rearwardly folded portion 42 or 44.

Along the end edges 2t) and 22, the cover sheet 14 is also formed with rearwardly folded

portions

54 and 56. It will be seen that the left-hand portion 54 is folded into the groove 40 along the chamfer 36, as indicated at 58. Similarly, the right-hand portion 56 is folded around the chamfer 38 which extends along the right-hand ange 34, as indicated at 60. This arrangement also assists in securing the cover sheet 14 to the board 12.

From -Fig. 3, it will be-seen that the right-hand rearwardly folded portion 56 is also formed with a lip `or flange 62, which is illustrated as being double-folded, in the manner of the

lips

46 and 48. When the boards are applied as roofing or siding, the end lip 62 on each lboard is adapted to overlap the front of the adjacent board, as shown to best advan-tage in Fig. 4. The lip 62 will flex slightly, and will compress the underlying portion of the adjacent board, so that the boards will be substantially flush with each other along the vertical joints.

The underlying board is secured by concealed nails 66 which are driven through the upper half flange of the board; the nails are covered by the lower half flange of the overlying board. In addition to the concealed holding device of the lower part of the overlying board, a firm support for the overlapping 4board may be secured by furring strip 70 to be held by nails 68, which also spaces the lower edge of the board outwardly by giving the board a slight pitch.

As shown in Fig. 5, the upper lip 46 on each board is adapted to be received in the lower groove 30 in the board above. The lower lip 48 forms an efcient drip edge, adapted to shed moisture.

Fig. 6 illustrates the construction of a modified board 72 which is the same as the yboard 10, except that -the upper and

lower lips

46 and 48 are replaced with generally chisel-

edged lips

74 and 76. These

lips

74 and 76 are formed by folding the cover sheet 14a rearwardly around chisel-

shaped edge portions

78 and 80 on the half-

lap flanges

24a and 26a. The rearwardly folded portions of the cover sheet 14a are designated 42a and 44a. It will be seen that each chisel-

shaped edge portion

78 or 80 has a bevelled or angled outer end surface 82 which faces laterally and rearwardly.

The lip 74 at the upper edge of each board 72 is adapted to be engaged with the groove 30 at the lower edge of the board above. The lower lip 76 forms an efficient drip edge.

Thus, the illustrated boards effectively exclude rain and wind at `both the horizontal and vertical joints, without any need for joint strips or the like. The boards may be applied by simple nailing operations.

Accordingly, the boards provide low cost siding or roofing material which is extremely easy to apply. The applied product is highly serviceable and very attractive in appearance.

Various other modifications, alternative constructions and equivalents may be employed without departing from the true spirit and scope of the invention, as exemplified in the foregoing description, and defined in the following claims.
