SECTIONAL ROOF.

Application filed October 27, 1922. Serial No. 597,299.

Roofs, of which the following is a 'speciiica-` tion.

My invention relates to sectional roofs and one object is to provide a root of interlocking sections which may be readily installed on a building without the aid of skilled help, and one which is leak and lire proof.

A further object is to provide a roof of this character whichcan` be readily removed from a building Without damaging any of the parts.

Other objects will hereinafter appear, and in order that the invention may be fully un deistood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a brokeny plan view of a portion of the root.

Fig. 2 is a longitudinal section on line II-II of Fig. l. Y f

Fig. 3 is a cross section on line III-III of Fig. 1.

Fig. 4 is a perspective view of one oit' the gutter slabs employed in carrying out the invention.

Fig. 5 is an inverted perspective view ofl the slab disclosed by Fig. 4.

Fig. 6 is an inverted plan view of one of the roof slabs.

Fig. 7 is a detail perspective view of a panel.

In carrying out the invention, I employ a plurality of gutter slabs 2, 2a, 2b and 2c. The body of each gutter slab 2 is provided at its upper portion with marginal longitudinal shoulders 4, a transverse lip 6 at one end, a recess 8 in one ot the shoulders 4, and oit sets 10 in the ends ot the shoulders 4 adjacent to the lip 6, see Fig. 4. The underside of each gutter slab 2 has a centrally-disposed longitudinal groove 12, a transverse groove 14 adjacent to the end opposite the, end containing the lip 6, a transverse shoulder 16 adjacent to the groove 14, and offsets 18 at the ends of the shoulder 16, see Fig. 5.

Each gutte-rslab 2a is similar to the gutter slab 2 as evidenced by corresponding reference numerals with exponents a excepting that the groove. 14, the shoulder 16 and the offsets 18 are dispensed with and instead the underside of the slab is beveled as indicated at 20 to rest squarely upon a rafter 30.

Each slab 2b is similar to the slabs 2a, eXcepting that each longitudinal shoulder 4b has a recesst8b and the groove 12a is dispensed with. Each slab 2C is similar to the slab 2,

excepting that the groove 12 is dispensed with and each longitudinal shoulder 4c has a recess 8.

24 and 24a designate roof slabs. The body of each roo-f slab 24 is provided at its underside with longitudinal grooves 26 and lugs 28 projecting into said grooves 26, see Fig. 6. Each roof slab 24a is similar to the roof slabs 24 as indicated by corresponding reference numerals with exponentsa, the chief difference being that in the present instance the longitudinal grooves 26a extend throughout the length of the slab 24a instead of terminating near one end there-ot1 as do the grooves 26. The` aforementioned diiiference is due to the fact that the lower ends of the roof slabs 24 project beyond the lower ends of the shoulders 4 and 4", while the lower ends of the root slabs 24a terminate at the ends of thev shoulders 4a and 4b.

The frame, work for supporting the gutter and the rootslabs above described may be made in any desired form. In the drawings, I have shown a plurality of rafters 30,

a number of which rest upon columns 32'V which in turn rest upon plates 34 which may correspond to the plates 34 shown in my copending application filed June 20, 1921, Serial No. 478,901. The rafters 30 are arranged at different heights, as shown by Fig. 2, to give the desired pitch to the roof and the intermediate rafters have offsets 31 to receive the upper ends otrthe associate gutter slabs.

In practice the root is laid by lirst placing the gutter slabs 2a in position and then the gutter slabs 2, the lower ends oit the slabs being arranged to overlap as shown in Figs. 1 and 2, so that rain cannot beat into the joints between the ends of said slabs. The transverse lips 6 and 6? on certain of the gutter slabs 2 and 2EL fit into the transverse grooves 14 ot the overlapping gutter slabs and further preclude the possibility of rain entering the joints between said slabs. The interlocking lips 6l and 63L and shoulders 16 lock the gutter slabs together from independent longitudinal inovenient, while the upper A,ends of the longitudinal shoulders of the gutter slab enter the oli'sets 18 of the overlapping gutter slab and thus prevent independentlateral movement of said gutter slabs. Any tendency of the gutter slabsl The spaces'betvveen the endmost gutter slabs and the plates 34 are closed by panels 40, Which are set in vertical grooves 4:2 and 44 in the rafters 30 andl the columns 32, re-

spectively, said panels being placed Ain position before the gutter slabs 2 and 2a, so that their upper margins `will bite into the grooves l2 and 12a and form a Watertight and fire-proof joint.

By Vthus overlapping and interlocking the gutter androofV slabs as shovvn and described, asubstantialleak-proof roof is obtained and shouldv it ever be desirable to enlarge the building itis only necessary to addother slabs to `cover such enlargement. The'. roof can also be readily taken apart should it be desirable to remove it for any purpose, Without damaging the diiferent slabs.k The slabs areV preferably made of reinforced concrete or other fire-.proof material to reduce the fire hazard when applied to garages, Warehouses, etc.

While I have shown the preferred construction of the invention, I reserve the right to make such other forms as properly fall Within the spirit and scope of the appended claims.

Having thus described my invention, what I claim'and desire to secure by Letters Patent, is:

l. In a roof structure, a gutter slab consisting of a body portion having a transverselip at its upper surface at one end and a longitudinal slot at its underside, a panel adapted to fit into said longitudinal slot, and a transverse shoulder at the under surface of said body portion at its end opposite the end containingsaid transverse lip.

2. In a roof structure, a plurality of gutter slabs consisting of body portions, longitudinal shoulders on said body portions having recesses at their sides, transverse interlockingv members at the ends of the body portions, roof slabs having longitudinal grooves, and lugs in said roof slabs extending into said longitudinal grooves and adapted to enter the recesses in the longitudinal shoulders of the gutter slabs.

In testimony whereof I affix my signature. in the presence of tivo Witnesses.
