ROOF STRUCTURE Filed July 28, 1937 2 Sheets-Sheet 2 I mn- I j v i. 0 FM 0 T0 F E'E I I I Patented Mar. 1, 1938 UNITED STATES PATENT OFFICE ROOF STRUCTURE corporation of Illinois Application July 28, 1937, Serial No. 156,052
This invention relates to roof structures and particularly to tile or slate roof structures.
In structures of this character it is customary to provide a base supported upon rafters, to cover this base with water proofing material, such as asphalt impregnated felt, to then place tile supporting strips in spaced relation upon the felt, and to then fasten the tile to these strips. The
strips, however, are nailed to the base through the felt covering, usually by toenailing, with the result that each nail perforates the felt and produces a source of leakage to the interiorof the building of any water or moisture which may get through or around the tile. Furthermore, in some roof structures the pan tile are fastened to the roof base by nails which also perforate the sealing felt, thereby affording further likelihood of leakage.
One of the primary purposes of my present invention is to provide a roof structure which will be leak proof and wholly impervious to the passage of water therethrough, irrespective of any leakage through or around the tile as the result of breakage or otherwise.
In the accomplishment of this result, my invention contemplates an impervious and imperforate covering over the roof base composed of the usual asphalt impregnated felt which, because of the employment of my invention, is not penetrated by nails in any portion of the roof area, thereby insuring that any water which may gain access to the space beneath the tiles will fiow over the surface of the covering material to the eaves without finding any opportunity of seeping through the material to the inside of the building.
More specifically my invention contemplates a novel manner of securing and holding the tile supporting strips in position without recourse to nailing through the covering felt and in this manner leaving an imperforate covering'surface which is wholly impervious to the entrance of water and moisture therethrough.
Other purposes and advantages of my invention will be further apparent as the same is better understood by reference to the following description when considered in connection with the accompanying drawings.
Referring to the drawings:
Fig. l is a fragmentary plan view of a partially assembled roof constructed in accordance with my invention;
Fig. 2 is a view partially in section and par-;
tially in elevation taken onthe line 2--2 of Fig. 1;
Fig. 3 is a fragmentary sectional view on the line 33 of Fig. 1;
Fig. 4 is a view similar to Fig. 1 showing a modified form of roof construction;
Fig. 5 is an end elevation looking upwardly toward Fig. 4;
Fig. 6 is a fragmentary view of a partially assembled slate shingled roof; and
Fig. '7 is a sectional view on the line l--'I of Fig. 6.
Referring now to the drawings more in detail and particularly to Figs. 1 to 3, inclusive, reference character 8 indicates the roof base formed of boards or sheathing supported upon suitable rafters, not shown. This base is covered by a layer of impervious material 9 such as asphalt impregnated felt which is laid in elongated sheets or strips nailed near their upper edges to the base B'by nails ll. The lower marginal edge of each succeeding sheet is lapped over the upper nailed margin of the previously laid sheet and. the overlapping margins are fixedly secured together and sealed against the entrance of mois ture therebetween by the employment of suitable plastic cement or the like.
After one sheet or strip of covering material has been laid and secured in position, a plurality of strip holding clips I2 are secured by nails l3 or otherwise to the roof base in spaced relation along the upper edge of the previously laid sheet 9 as indicated in Fig. 1. Each clip comprises a fiat base, the upper end of which is nailed to the roof base, as explained-and the other end is shaped to receive the tile supporting strips which are later positioned therein. While these clips -may be of various shapes and constructions,
those herein illustrated are made from a fiat piece of sheet metal which is cut intermediate its ends to permit the wings or flanges 14 to be upturned, as shown, for the accommodation therebetween of the tile supporting strips I5. I These clips are spaced apart across the roof in accordance with the center spacing of the cap tiles l6 and after each row of clips has been secured in position the succeeding sheet of covering material 9 is laid so that its lower edge overlaps the fiat base portionsof the clips and, when cemented down, provides an impervious and imperforate covering for the base which is not penetrated by the clips so as to permit the entrance access to the space beneath the tile.
positioned in the clips, as shown, and are secured against displacement by nails l1 driven through the clip wings into the strips. To assist in maintaining the strips against endwise movement, angle brackets l8 may be secured to the base along the eaves against which the lower ends of the strips l5 abut, thereby adding strength to the structure.
The pan tiles [9 are now laid in position between the strips l5 and are secured in position by nails 2! extending into the strips [5. The cap tiles l6 are then positioned over the strips l5 and secured thereto by nails 22, thereby completing the roof structure.
It will be obvious that in accordance with my invention the tile supporting strips are securely anchored to the roof base without driving any nails or fastening means of any kind through the layer of impervious covering material. The strip holding clips are anchored to the roof base beneath the covering material, while their strip holding ends project above the covering to support and retain the tile supporting strips. The fiat base portion of the clips which extends between the overlapping margins of the covering material does not interfere in any Way with the laying or cementing of the material, nor does it provide any opening through the material which might afford access to the entrance of water.
In the form of my invention shown in Figs. 4 and 5, the pan tile I9 instead of being laid directly upon the covering material of the roof is supported upon strips 23 located intermediate the cap supporting strips l5. In this instance the pan tile supporting strips 23 being about two inches high necessitate the cap tile supporting strips l5 being about six inches high. The total height of the roof therefore is about two inches higher than the height of the roof shown in Figs. 1 to 3 wherein the pan tile rest directly upon the sheets of covering material. I
In the form of the invention shown in Figs. 4 and 5, twice the number of clips l2 are employed as are necessary in the construction shown in Fig. 1 but their manner of attachment to the roof base and to the tile supporting strips is identical in each instance, the ultimate result being that the roof covering is imperforate and unbroken throughout its area, thereby obviating any possibility of leakage even though water might gain In the form shown in Figs. 6 and '7, the base 8, the seal 9, the clips l2 and the strips 24 are assembled substantially in the manner previously described except that in this instance instead of tile being supported by the strips, the strips are all only approximately two inches high and are crossed by similar strips 25 nailed. thereto and upon which the slate shingles 26 are supported and to which they are attached by nails 21. a
The leak proof character of this type of roof is identical with that of the two types previously explained because, as in the other instances, the sheet of covering material is imperforate throughout the area of the roof and no leakage therethrough is possible even though water gain access to the space above the seal.
It should beapparent from the foregoing that my invention provides a leak proof roof by affording an imperforate seal beneath the tile or shingles, as the case may be, which precludes any leakage of water therethrough irrespective of the water tightness f the overlying covering, whether it be of tile or shingles.
While I have shown and described those preferred embodiments of my invention which at present seem most desirable, it should be understood that the structural details are capable of considerable modification and variation without departing from the scope of the invention as defined in the following claims.
