This invention relates to the roofs of portable buildings` and is a modification and simplication of the roof structure described in the specification to British Patent No.

c 129,777 and it has for its object a construction of conical roof for use with circular buildings such, for instance, as the mud huts used bythe natives of tropical countries,

which 'huts are at the present time roofed lo with various vegetable material which not only harbours vermin and is consequently eminently unsanitary but has a very transitory life. Y ccording to the present invention the 15 roof comprises a main roof ring ot substantially the diameter of the wall of the building, a secondary ring of equal diameter to, spaced apart from and disposed below said main roof ring, a central support compris- :1,1 ing two superimposed cone-shaped rings spaced at a suitable distance apart by stays or uprights, a plurality of sheets adapted to be grouped and arranged to form a ceiling, the upper ends of said sheets being sup- -v ported on and fixed to the lower of the coned rings forming part of the central support, their lower ends being supported on the secondary ring, and a plurality of sheets adapted to be grouped and arranged to form the l?" roof, the upper ends of said sheets being supported on and iXed to the upper of the coned rings forming part of the central support, their lower kends being supported by and Xed to the main roof ring. i5 In the accompanying drawings which illustrate this invention Figure l is a view of a hut iitted with the improved roof which is shown partly in section.

Figure 2 is a broken view in section on an c enlarged scale showing the method of positioning the lower ends of the roong and ceiling sheets, and Figure 3 isa similar view showing the attachment of the roofing and ceiling sheets and the cap or cowl to the central support.

Throughout the views similar parts are marked with like numerals of reference.

Theroof consists of a roof proper l and a D ceiling y2 each of which'is made up `of a pluywardly as shown in Figure 3, the cowl being rality of sheets of triangular form. At the edges of these sheets which may be of any suitable metal or other suitable material is aV single corrugation 3 so that when the adjacent sheets are in place and overlap the 55 corrugations form an interlock. The outer or lower ends of they rooiing sheets are supported by and fixed to a ring 4, the lengths f of said sheets being such as will allow of a substantial overhang from the wall 5 of the 60 hut, said ring being preferably formed in a plurality oi' sections for convenience in packing and storage. The uppery ends of the rooiing sheets are supported by and fixed by bolts 6 (Figure to acone-shaped ring 6 which Jforms the upper part of a central support. The upper ends of the ceiling sheets 2 are supported and tiXed to a cone-shaped ring 8 which forms the lower end of the central support. The lower ends of the ceiling sheets are supported on a secondary ring 9 spaced apart from the ring 4 by means of distance pieces 10.

rIhe upper and lower rings 7 and 8 of the central'support are spaced at a suitable disvtance apart as to provide the desired cavity between the ceiling and the roof and are positicned by means of a plurality of vertically disposed metal stays l1.

The apex of the roof is covered in by a cowl 12 and in order to provide an air outlet said cowl may be supported on the upper ends of the stays ll which for this purpose are continued beyond the ring 7 and bent over outsecured to said strips by the bolts 13.

The upper ends of the ceiling sheets 2 are preferably secured in position by an L-shaped ring 14- placed around the stays l1 to which it is secured by bolts 15, but if desired said ceilingsheets maybe secured to the ring 8 by lbolts or the like.,

i The lower ends of the roong sheets are secured to the main rootv ring 4 by means of clips 16 which" are adapted to engage the horizontal'rib of said ring and are secured to the sheets by means of bolts` or the like 17 as shown in Figure 2.

Tlieroofsforming the subject of this in- A vention are chieiy intended to be used in-coni the aperture at the base of the central support with line wire gauze, the ybuilding may e made mosquito prooi.

The internal diameter of the central sup-V port mustbe such as will provide ample room or a man to stand within it, in order to enable the roofing and ceiling sheets to be secured to their respective supporting rings.

lVhat I claim is 1. In a roof for circular buildings the conibination of a skelet-on framework comprising a plurality of vertically arranged bars, a ring secured to the lower ends of said bars, a second ring secured to the upper ends of said bars, a supplementary ring secured to said bars a short distance below the last named ring, a central support comprising two cone-shaped rings arranged one above the other, means for spacing said rings at a suitable distance apart comprising a plu rality of vertically disposed stays, a plurality of sheets of triangular form adapted to be grouped and arranged to form a ceiling the upper ends of said sheets being supported 'on the lower of the cone-shaped rings forniing the central support, means comprising a clamping ring for securing said sheets to the central support, their lower ends resting on the supplementary ring, a plurality of sheets of triangular form adapted to be grouped and arranged to form a roof the upper ends of said sheets being supported on and fixed to the upper of the cone-shaped rings forming the central support, their lower ends being supported by and liXed to the second named ring.

2. In a roof for circular buildings the combination of a skeleton framework comprising a plurality of vertically arranged bars, a ring secured to the lower ends of said bars, a second ring secured to the upper ends of said bars, a supplementary ring secured to said bars a short distance below the last named ring, a central support comprising two coneshaped rings arranged one above the other, means for spacing said rings at a suitable distance apart, a plurality of sheets adapted to be grouped andarranged to forni a ceiling the upper ends of said sheets being supported on the lower of the cone-shaped rings forming'the central support, means for securing said sheets to the central support, their lower ends resting on the supplementary ring, a plurality of sheets kadapted to be PETER NORMAN NISSEN.
