lApplication led February 7, 192.4. Serial No. 691,261.

My invention relates to improvements in roof coverinffs and more particularly to those embodaying a flexible backing and shingles of 'slate or the like on the outer side of said backing.

The object ofthe invention is t'o provide a roof covering in which portions of the backing are exposed to view at certain edges of the shingles to give very pleasing ei'ects,

rfor instance, to give a thick appearance to the shingles when in reality they may be very thin, or to dis lay a color along certain edges of the shingles contrasting with the color ofh said shingles.

lVith the foregoing in view, the invention resides inthe novel subject matter hereinafter described and'claimed, the description being supplemented by the accompanying drawings.

Figures 1 and 2 are respectively an elevation and a sectional view showing one form of rooting vunit constructed in accordance with my'lnvention, Fig. 2 being cut on line 2-2 of Fig. 1. p

Figure 3 is a planview showing a numberfof the units laid upon a roof.

' "Figures 4, 5, 6 and 7 are plan views showing roofing units of different forms.

Fi re 8 is a sectional view on line 8-8 301 ofA Fig. 7.

In the form of construction shown Figs. 1 and 2, the numeral 1 designates a iexible backing sheet upon the lower portion of which, a shingle 2 of slate or other 85 desired material, is secured. The backing sheet 1.is -preferably covered with a coating 3 of. asphalt or other yieldable, adhesive material, and this material is utilized for securingy the shingle 2 in place.

The backing 1 and its coating 3 are shown -`projecting beyond one vertical edge of the shingle 2 as indicated at 4, and also project- -ing downwardly beyond the lower end of the shingle as disclosed at 5. By this ar- 475 rangement, when the roofing unitsl are laid upon a roof as shown in Fig. 3, the portions 4 and 5 will be visible and lwhen the roofv is viewed at distance, will give the appearance that the shingles 2 are rather thick, when in reality they ma be thin.

. In Fig. 4, shing es 2a are shown u on the lower end portions of a backing s eet 1,

one of said. shingles being inwardly spaced from `one vertical edge .of the sheet 1Il as 5l! indicated at 4. Also, theshingles are horiat 5a. When this form of roofing unit, with inv zontally spaced in order t@ expose the backing between them, as inicated at 4", and all shingles are upwardly spaced from the lower edge of the backing sheet as indicated io any desired number of shingles secured upon a backing of any suitable length, is laid upon a root', the effect is the same as in connection with the construction shown in Figs.l 1 and 2, but as more shingles are provided on each backing sheet, the roof m'ay be more rapidly laid.

l In Fig. 5, I have illustrated shingles 2b mountedupon a backing l" in the samemanner as shown in Fig. 4 with the exception *o that the lower edge of the backing sheet does not extend below the shingles. This same idea may of course be used when only one shingle is attached to each backing sheet, and when roofing units of this type are applied tothe root', they have some tendency to (present the appearance of thick shingles an a very attractive roof is produced.

Fig. 6 illustrates a backing sheet 1c and a shingle 2 thereon, with said backing sheet extending below the shingle as at 5, but not extending laterally from said shingle. l'Vhen units of this 'type are laid upon a roof, the vertical edges of the shingles 2" are of course in rather close relation with each other, but the projecting portions 5c of the backings 1c, give the appearance that the shingles arerather thick, even thou h they may not be. I-t desired, it will be o vious that a horizontally elongated strip' might be used in place of the backing sheet lc-and that a horizontal row of the shingles 2c could be applied to such a strip, in upwardly spaced vrelation with its lower edge.

Whenever desired, any of the exposed 95 portions ofthe backing sheet, ma be coated with granules and in Figs. 7 an 8, I have shown a construction identical with that 'illustrated in Fig. 4, with theexception 'that the portions 4, 5 and 4 and also the por- 100 tion of the coated backing along the upper ends of the shingle 2. are provided with a covering of granules, as indicated by the numeral 6. These granules are of contrastingcolor with respect to the shingle or shingles and hence `a very attractive roof is produced. The granules at the upper ends of the shingle or shingles, constitute a bolster to assist in supporting an overlapping rooting unit and. it will be seen that these 11G granules, may be uSed without any other granular coating and that -they need not necessarily be of a color contrasting -With the shingles, as they are obscured from view.

In the foregoing, I have described a number ofiforms of construction and haveillustrated such kforms in` the accompanying drawings, but it is to be understood that my invention may be embodied also in still further types of constructions.

I claim;

1. A roof covering unit comprising a onepiece flexible backing sheet,`rigid shingles of greater durability than the sheet secured in horizontally spaced relation to portions of said sheet and imparting rigidity to' said portions while exposing restricted interveiling portions of .the sheet, Said shingles being spaced upwardly from the lower edge of the sheet to expose a restricted horizontal portion ofthe latter, the upper ends of the shingles being adapted tov be overlapped by an overlying shingle-carrying sheet whose shingles span the first mentioned exposed portions of the sheet, granules secured upon the aforesaid exposed portions of the sheet to protect the same and to impart suicient rigidity thereto to prevent puckerin between the shingles or curling at the Iower ends thereof, said granules contrasting in 'parting rigi color with the shingles to give the appearance of thickness to the latter.

2. A rooting unit comprising a flexible backing sheet, and a rigid shingle of greater durability than said backing sheet secured upon the upier -side of the latter and imof the backing sheet projecting horizontally fromthe shingle to merely abut 'an edge of an adjacent backin sheet without underlying or overlyingte latter, the lower portion of said backing sheet projecting downwardly beyond the shingle, and Weather-resisting granules secured upon said projecting portions of the backing sheet to impart sucient rigidity thereto to prevent curling and to protect said projecting portions/y said granules being ot a color contrasting with the shingle to givethe appearance of thickness to the latter..

3. A structure as specified in claim 2; and additional granules disposed on the backing sheet along vthe upper edge of the shingle but terminating short of the upper end. of the backing sheet to form a bolster assisting in supporting an overlying roong unit.

In testlmony whereof I have hereunto affixed my signature.
