Application filed December 28, 1911, Serial No. 668,320. Renewed August 24, 1812. Serial No. 716,880.

To all whom it My concern Be it known that I, THoMAs R. HACK- woi'rrrr, a citizen of the United States, residing at Richard City, in the county of Marion and State of Tennessee, have invented a new and useful Roofing, of which the following is a specification.

The present invention aims to provide a roof covering of novel and improved form, the covering consisting of a series of tiles formed in place upon the roof, means being provided for holding the tiles upon the roof, which means constitutes a part of the molding structure in which the tiles are fashioned.

A further object of the invention is to provide a means for yielding'ly separating superposed layers of tiles in a roof, the said means consisting of a sheet of flexible mate rial. preferably water-proof, one end of the sheet being interposed between the overlapping ends of successive layers of tiles. the other end of the sheet overlapping the exposed ends of one layer of tiles, the construction being such that the last named end of the sheet of material constitutes a temporary covering for the tiles, which covering may be severed, after the tiles are in place.

With the foregoing'and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement-of'parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanving drawing,Figure 1 shows in top plan. a roof constructed in accordance with the present invention, parts being broken away; Fig. 2 is a section upon the line 2 -2 of Fig. 1; Fig. 3 is a perspective showing the primary and secondary bars and the separating plates; Fig. 4 is a perspective showing a 'modified form of separating plate; and Fig. 5 is a perspective showing a modified form of secondary bar.

In the accompanying drawings, the numeral 1 indicates the foundation which, ordinarily, is fashioned from the boards ofthe roof. in angle member 2 extends along the side edges of the roof. and another angle member 3 extends along the caves. The

flanges 4 of the angle members .2 and 3 are 1' attached to the foundation 1, the flanges 5 of the angle members 2 and 3 upstanding, to retain in place upon the roof, the covering structure hereinafter described.

Secured to the foundation 1, and preferably in parallel relation, and disposed ordinarily at right angles to the direction in which the roof slants, are a series of primary bars 6. The separating plates 7 are pro vided, the same being, as shown in Fig. 3, of tapered form. The narrower ends of the separating plates 7 are disposed in abutment with one of the primary bars 6, the wider ends of the separating plates 7 protruding beyond the next adjoining primary bar. The secondary bars 12 alternate with the primary bars 6, the bars 12 and 6 bein preferably disposed'in parallel relation. ach of the secondary bars 12 connects one set of separating plates 7. the bars resting upon the upper edges of the next adjoining set of separating plates 7 If desired, the separating plates 7 may be connected with the foundation 1 by means of securing elements 22. The wider ends of the separating plates 7 protrude beyond that secondary bar 12 whereby they are upheld, and interlocking elements are provided, for holding the separating plates 7 assembled with the secondary bar 12. These interlocking elements may consist of notches 14 in the lower edges of the wider ends of the separating plates 7, which notches 14 are adapted to interlock with notches 15,, formed in the upper edges of the secondary bars 12. The plastic material, preferably concrete or the like, denoted by the numeral 8, is interposed in the rectangles formed by the bars 6 and 12, and

by the separating plates 7 Noting particularly Fig. 2, it will be observed that each layer of plastic material 8, overlaps the next layer 9 below it, in the common and well known manner. Interposed between successive layers of plastic material is a layer of vieldable, waterroof material, which may be heavy paper,- flilt or the like, denoted specifically by the numeral 9. One end 10 of the layer 9 lies between successive layers 8 of plastic material, the other end 11 of each layer of flexible material protruding beyond one layer of plastic material and overhanging the next layer of plastic material, to serve as a covering therefor. After the plastic material 8 has set sutiiciently, its end 11 may be cut oil or severed otherwise The tiles which are formed by the plastic material, between the elements 12, 7 and 6, may be retained upon the foundation 1, by means of securing elements 21.. preferably spikes or the like. entering the foundation 1.

If desired, the secondary bars and the separating plates may be fashioned from metal. Under such circumstances, the secondary bars, denoted specifically by the numeral 16, may be equipped with key-hole slots 18. The separating plates are denoted by the numeral 17, and each separating plate terminates in 'a head 19, adapted to pass through the constricted portions of the slots 18, heads 19 being connected with the body portions of the plates 17, by reduced necks 90, adapted to rotate in the enlarged portion of the key-hole slot 18. The heads 19 may be inserted through the restricted portion of the slot 18, whereupon, if the late 17 be rotated, until the head 19 stans at right angles to the constricted portions of the slots 18. an effective lock will he formed, holding the separating plates 17 interengaged with the secondary bars 15. I

The primary bars 6 represent the thickness of the thinner ends of the tiles which are formed between the elements 7.. 16 and 12. The wider ends of separating plates 7 represent the extreme thickness of thethicker ends of the tiles.

Owing to the fact that the layer 9 of yieldable, water-proof material is em loyed, one layer of tiles will be prevente from cohering with the next layer of tiles, to form a monolithic structure. Owing to the water-proof nature of the material 9. the moisture will not be absorbed out of th tiles, it, of course, being understood that th e tiles are formed upon the roof, in plastic condition. The layer 9 of yieldable material constitutes a cushion between successive series of tiles. so that if the tiles are trodden upon, or strained, due to wind-stress, a breaking of the roof covering will be avoided.

It is to be noted that the separating plates 7 of one series, break joints with the se a- .rating plates of the next series, and t as leakage bet-ween adjoining tiles is reduced to a minimum. The layer 9 .of water-proof material covers the entire space between the bars 6 and 12, and by this means, leakage is further prevented.

That end 11.01? the layer 9 which protrudes beyond the bar 12, overhangs the exposed portions of the tiles, and serves to protect the tiles. from the sun, during the time that the'concrete is setting. The moisture is thereby retained in the tiles. and the tiles are prevented from injury, arising from any other source. This protruding end 11 may be cut away, after the'tiles have acquired a suflicient set.

It will be understood readily that the angle members 2 and 3 serve to define the margin of-roof covering, as clearly shown in Fig.1.

A roof comprisin a foundation; primary bars a plied to t e foundation; separate series 0 separating plates, the plates of each series abutting against one primary bar and extending across the next primary bar; separate sets of secondary bars alternating with the primary bars, the'secondary bars of each set connecting the plates of one series'and restin upon the plates of'the next series; and over apped layers of plastic material interposed between the bars and the plates.
